For the record, Minnesota currently has a complete ban on sports betting.

We've seen a couple other states that allow sports betting go after prediction markets. Personally, I feel that any state that allows sports betting is going to struggle to argue a case to ban prediction markets because you're essentially arguing over implementation details. Even arguments that certain prediction markets are ripe for insider trading or morally wrong fall a bit flat when you realize that traditional sportsbooks let you bet on things like college basketball player props and the little league world series.

I'm still not sure Minnesota will win their case, but it feels like that detail gives them a lot better chance of winning compared to many other states.

mayneackabout 22 hours ago
Arguing over implementation details is a pretty common thing for laws to do. Maybe it would weaken the logical consistency of their laws, but that's not really a thing that matters.

Why do states allow hunting some animals and not others? Why do states distinguish between different forms of income to tax? It's all implementation details.

superfrankabout 21 hours ago
I wasn't saying we shouldn't debate the implementation details. I just think they should be separate arguments.

It's like if someone killed my dog with 3d printed gun and so everyone started talking about banning or regulating 3d printers. It's like, yes, debating 3d printer regulation is probably a worthwhile debate to have, but regardless of where we end up on that it doesn't change the fact that that person killed my dog.

We should be having a debate as to whether there are certain things that are off limits to bet on, but regardless of where that debate goes, if a state has banned sports betting, it should be banned regardless of the platform.

This is both one of my pet peeves and a thing that legislators seem to love: Somebody does a thing that is already illegal, but in a slightly novel way. Perfectly valid statute exists to prosecute, but legislators want to be seen as doing something, so they pass another law to make the already criminal action more specifically criminal.

Arguably bans on cellphone use while driving are a good example. It's not that it isn't bad, it's that distracted driving already carries a hefty fine without being specific as to the mode of distraction. So does causing an accident, which presumably is the harm we're actually trying to avoid.

I think their point was that your "going to struggle to argue a case" belief does not logically follow from a need to argue "over implementation details"

jeltzabout 22 hours ago
I don't see why it even would weaken the logical consistency. Just because a state allows gambling does not mean they need to allow anyone to open a casino or betting site. You still need to apply for a licence and follow local regulations. If the prediction markets make sure to follow the regulations they should obviously be granted a licence to operate.

I think you could make a case in separating the two, of course opening further discussion, but because sports betting takes place in a comparatively very controlled environment I think the risk profile is pretty different versus, idk, betting that the temperate will be at or above a certain point and then someone sticks a hair dryer on the thermostat[1]. Cheating can happen in sports of course, but the risk profile and real-world impact I think is quite a bit different. Worth discussing, but I think that's an important distinction.

Separately, I believe over time that prediction markets will become the source of real world truth. Why? Because money is at stake and so validity and verification matter. It'll be interesting to see how, if this comes to fruition, how laws in states like Minnesota affect news reporting and journalism. It seems likely to me that at a certain point prediction markets will buy traditional media and news outlets to hire out the fact-finding and reporting teams to ensure ground truth, and of course to use journalism as the gateway to the market. So you read an article "China disappears random person" and then at the end you click a button and bet whether that person is alive or dead or whatever.

Congratulations, you just created a murder market. Create “Is person X dead?”, and put a large limit order buying No. Anyone with means can capitalise on it by fulfilling the physical obligation of the market and buying up the limit order. Don’t create the murder market.

It would be a stupid thing to do given the trail, bit it gives the person ordering it sort of plausible deniability.

The state can make it unprofitable to murder. Meaning that the existence of such a market is not a source of potential profit.

That's kind of the point I was getting that. That's not really an argument about prediction markets, it's about what things should we be allowed to bet on.

I'm looking at FanDuel right now and I can bet on 1v1 eSports games of FIFA. The bets aren't even just who will win, but it's things like how many goals will a team score or who will score first. During the last Superbowl books were offering bets on things like what color tie the announcers would wear. I get that there's maybe a slight difference between that and betting on what words a sports announcer will say during the broadcast, but IMO, you're splitting hairs. They're both very easily to manipulate and very open to insider trading.

I think you probably agree with this, but IMO, there needs to be two separate conversations. One, are prediction markets sportsbooks by another name? Two, are there certain markets that we should not allow betting on?

Personally, I think the answer to both of those is yes, but I think if you smush them together into one conversation it makes things really messy.

cameldrvabout 22 hours ago
The environments of various bets have varying degrees of "control" from insider trading. I wouldn't say that sports is more controlled than most other environments. Point shaving scandals are certainly as old as college sports.

The real question is what the purpose of prediction markets are. For sports, there isn't really much of a purpose to the markets except entertainment for the bettors, and harvesting cash for the bookies. There are also various advantage bettors (who may be involved in corruption or not), who attempt to harvest cash from some combination of the bookies and the bettors. Generally IMO these are bad due to simple human frailty though. We figured out a long time ago that for the most part, making gambling available to the general public was a net negative to society, because it mostly transfers money from addicts to big corporations, destroying lives.

For major world events, one purpose of prediction markets is just to generate a price. It's potentially useful for people to know that, in an adversarial market, what the aggregate probability of an event is. It can also be useful theoretically to hedge risks. Whether it's practical to do that depends on the depth of the market though, and with the current markets, it's not. Even more traditional "prediction" markets like commodity futures aren't deep enough to usefully hedge most risks. For example, you might think that major oil companies might hedge future pricing risks, e.g. they want to drill an oil field with a high production cost, but they're worried that the price might go down before they finish production on the wells. Generally though, the markets aren't deep enough for them to be able to do this, so they just won't drill fields that have a production cost more than roughly the lowest price in the past 20-30 years, depending on the age of the executives in charge of the decision.

There's this other purpose of prediction markets though, which is money/information laundering. People may have secret information where their employer has a strong interest in it remaining private, however the person with the information isn't that well compensated, so they monetize the information on prediction markets. On the darker side, you can have wildly illegal markets like "assassination futures" where people bet on when someone will die, and you can bet on a particular outcome, and then make it come true. There are lots of markets somewhere in the middle where someone can take an action in the context of them being a trusted agent of an organization, but instead of following their duty as an agent, they do what is profitable based on their bets in the prediction market.

Overall, IMO there are some good uses for prediction markets that allow people to hedge risk on both sides and enable useful economic activity, but most of the uses I've seen in practice are a net negative.

Terr_about 20 hours ago
I think the argument for hedging is further weakened by how large actors have other (better?) ways to hedge, such as with futures contracts or insurance policies.

Those may have the added benefit of protecting you from price changes. If I need widgets and I'm worried a geopolitical event will disrupt supply, the money from a "won" bet might be minimal compared to the new costs as everyone raises the price of widgets.

I think sports betting is a lot less harmful than prediction markets. With sports betting if someone throws a game to get a pay day, for instance, the only real consequence is on the reputation of the sport. In prediction markets, people can do all sorts of awful things to make money as insiders..

Most available data suggests that sports betting is much worse for the people making the bets, as it better targets people with poor impulse control. Bad bets in political markets aren't causing measurable increases in bankruptcy and domestic violence rates (https://thezvi.substack.com/p/the-online-sports-gambling-exp...).
RajT88about 20 hours ago
I live in IL, and digital slots have taken over so many spaces. Online sports betting is bad enough, but more than that is going on.

Not just bars, but restaurants. Places you might take a date for nice Italian food have little corners with digital slots. Gas stations, Taco joints, sometimes an entire business in a strip mall dedicated to digital slots.

It's insane. The only place like it I'd seen prior to a some years back was Nevada. Businesses must be making crazy money off of them to be so prolific in putting them in, and that money comes from somewhere (i.e. not likely to be casual players).

strikingabout 20 hours ago
I don't think that article supports your claim that bad bets in political markets aren't causing measurable increases in bankruptcy and domestic violence rates. It only tells us about online sportsbetting, and it was written in 2024 before prediction markets really took off. If anything, it provides evidence weakly in favor of the argument that bad bets in political markets would negatively affect the bettors.

Likely because this type of betting is still niche. Give it some time.

There's a pretty decent counter-argument though: Prediction markets are just a market for users to counterparty each-other. Which means, technically, for every trade there is a winner and a loser, and both the winner and the loser are generally just normal people (or market makers). Polymarket/Kalshi just take X% on the top as a fee. Versus, with sports betting, the counterparty is the casino. Its the difference of trying to outsmart a massive casino, versus a more peer-to-peer system; the potential for ROI is (probably) higher in prediction markets.

I am still very, very anti prediction market, to be clear. But that is one reason why I would agree with a soft statement like "prediction markets are less harmful than sports betting" (in much the same way that a handgun is less harmful than a fully automatic rifle).

potatototoo99about 16 hours ago
The counterparty in prediction markets are whales though, and those are the few players making money off it. The ROI is also less negative in casinos and sports betting than prediction markets.
doolsabout 22 hours ago
Yeah, prediction markets are like if you could bet on arbitrary decisions a coach or manager might make. Like starting lineup or different trades of players between teams or the size of a players contract in dollars, rather than events that happen during gameplay. There are people who know the facts already but the public does not.
superfrankabout 23 hours ago
First, over 90% of the wagers on Polymarket and Kalshi are already on sports (quoting John Oliver's Last Week Tonight on that one). Despite the headlines, Kalshi and Polymarket are mainly just sportsbooks.

Second, while yes, some of the markets available on prediction markets can push people to do awful things, there are plenty that are harmless. I'm cherry picking to make an extreme point, but I would so much rather have someone betting on what the temperature in Los Angeles is going to be tomorrow on Kalshi than betting on who will win the little league world series on DraftKings.

I support regulation saying certain things should not be allowed to be bet on, but allowing bets on morally questionable things isn't a quality unique to prediction markets.

jeltzabout 21 hours ago
Technically they are betting exchanges. But they also probably have contracts with some of the big sportsbooks to provide liquidity too making them also kinda a sportsbook. I used to work at a betting exchange and we did have liquidity partners that made sure to increase the liquidity on our exchange.

>Kalshi and Polymarket are mainly just sportsbooks.

How? They sell contracts between two users. One side each. Completely different from a sportsbook where users are betting that the lines they set are not correct.

antasvaraabout 7 hours ago
I think the case is pretty clear regardless: gambling is supposed to be a state-regulated activity, and Kalshi is gambling but is regulated by the CFTC at the federal level. So I think the argument is "we want to be the ones to regulate sports gambling in our state," whoch is independent of whether or not it's currently legal in the state.

Or maybe I'm wrong, and "we don't want sports gambling" is different legally from "we want to be the regulator of gambling." But it seems like they're just variations of the same question, which is: do states have the power to regulate this?

dragonwriterabout 16 hours ago
> Personally, I feel that any state that allows sports betting is going to struggle to argue a case to ban prediction markets because you're essentially arguing over implementation details.

This seems to be based on the false assumption that state legislation on distinct but related topics must generally be based on a coherent, consistent rationale. This is, very much, not the case under any law that binds US states, nor is it a rule that, despite not existing in binding law, is in practice imposed as a constraint on state governments by the actions of the voters.

(Conversely, even if such a rule was imposed, in law or otherwise, any state that has rules regulating the offering of insurance contracts, including who could buy insurance against what events—which, as it turns out, every state does—would have exactly the basis they need to apply the same kinds of rules to prediction markets.)

My guess would be that either A) that's tribal land and there's an exemption for that in the current laws or B) they have a casino, but don't offer sports betting or C) they only allow sports betting on the property by either requiring all bets to be placed in person or the app they offer is for sportsbetting is geo-fenced to their property (which is how states like WA do it)

robvirenabout 10 hours ago
Long story short it is a compromise between the Mdewakanton Sioux, the state, and Canterbury to keep gambling exclusive to Mystic Lake Casino and Caterbury. The State flirted with the idea of expanding gambling and started moving in that direction, but Mystic basically now props up Canterbury, lets them have some amount of gambling on site, and the State did not expand gambling and generally is protective of Mystic. It's like a pressure release valve on gambling with some small kickbacks to the nearby legacy horse racing track. It's a strange local arrangement. Grew up in Prior Lake and had a few tribe members in school so this is just my bias on the arrangement.

The CFTC uses the following argument in their press release: [1]

> This Minnesota law turns lawful operators and participants in prediction markets into felons overnight,” said CFTC Chairman Michael S. Selig. “Minnesota farmers have relied on critical hedging products on weather and crop-related events for decades to mitigate their risks. Governor Walz chose to put special interests first and American farmers and innovators last.

Its an interesting angle; how do you draw the line between "a prediction market about what the temperature will be" and a futures contract that's used as a legitimate hedge? Minnesota's law is EXTREMELY broad in its definition: [2]

(e) "Prediction market" means a system that allows consumers to place a wager on the future outcome of a specified event that is not determined or affected by the performance of the parties to the contract, including but not limited to: (1) an athletic event or game of skill, or portions thereof or individual performance statistics therein; (2) any game played with cards, dice, equipment, or any mechanical or electronic device or machine; (3) war, state or national emergencies, natural or human-made disasters, mass shootings, acts of terrorism, or public health crises, or the ancillary effects thereof; (4) any event or events happening to a natural person or group of people;(5) a federal, state, or local election, or the actions or conduct of the federal, state, or local government and the government's agencies, employees, and officers; (6) legal actions, including but not limited to a civil or criminal suit, grand jury action, jury trial, settlement, plea, or conviction; (7) the death, assassination, or attempted killing of a person or group of persons, or mass casualty events; (8) short-term weather events or conditions; (9) events in popular culture, including but not limited to awards and the date a piece of entertainment will be released; and (10) whether a person will make a particular statement.

There's a bunch of exceptions that reference prior laws, which I haven't gone through, though they'd likely have to exempt, you know, Chase Bank, because if not that definition would clearly disallow Stocks.

I mean, that's exactly why a state has the right to regulate this, historically it has been an extremely regulated activity. You can personally feel however you want, but the fact that a state does allow sports betting does not diminish this even slightly.

This has been banned for generations. It's called gambling. Of course, we all have to sit through another round of Silicon Valley pretending they've discovered some new exciting business model that's just vice.

If you don't actually sell someone something illegal, but take them to buy illegal things using the safety of your car so they avoid detection - are you innocent?

Drinking and driving exists and is illegal, but going to the grocery store isn't. Should we do an all or nothing sort of ban, either allowing drunk driving or banning cars altogether? No one would do this - some uses are illegal, most aren't.

A law that allows legal uses of your car but disallows illegal activity isn't all that unheard of.

While it's obviously sports betting, the fact is that federal law gives the CFTC the power to determine what is and isn't a future and expressly preempts state intervention in futures markets. And, the case as to why futures markets generally should be subject only to federal oversight is quite strong IMO. So, the case can quickly become whether or not the CFTC should consider sports betting to be a future, and judges typically defer to the executive branch when it's not obvious (and in this case I don't think it is, the bar owner in Philly hedging an Eagles loss is an entirely plausible, albeit unlikely and uncommon, situation).

While I am partial to the argument that the CFTC is actually taking away the states' 10th Amendment police power right, that is a somewhat tenuous case in comparison to the enumerated right of the federal government to provide sole jurisdiction to the executive branch to enforce a law (and not to mention a law that impacts interstate commerce).

I imagine Minnesota loses this case and what's far more likely is either a more liberal congress changes what is a future by law or a more liberal executive branch reduces the protections for Kalshi et al.

yieldcrvabout 21 hours ago
90% agree, the CFTC doesn't consider these futures contracts, it regulates them under its "contract market" authority, that Congress designated and updated periodically over time

This is the authority on the CFTC's own website on prediction markets "For more information" section

https://www.cftc.gov/LearnandProtect/PredictionMarkets

https://uscode.house.gov/view.xhtml?hl=false&edition=prelim&...

And yes, both the Supremacy clause and the Interstate commerce clause neutralize any 10th amendment claim, unless the Federal government or any of its agencies was completely mum on the activity. But since the Federal government has exerted authority over that industry, via the interstate commerce clause, states can pound sand.

I could imagine cases where prediction markets could offer some actual insight, but in practice they seem few and far between. Most markets I've seen devolve into one or more of: betting on unimportant events (e.g. sports games), insider trading, or poorly written ambiguous resolution criteria. It's just hard for me to imagine that, on net, these markets will offer more societal good than the harm we've seen from sports betting.

I could imagine that there's very little insight to be gained when some 23 year old has so little hope for his financial future that he's spending some of what he earned last night delivering food for uber eats on making a completely uninformed bet on a geopolitical situation involving a country he couldn't even find on a map just in case it pays out well enough that he can afford some of the needed medical care he's been putting off. That's the type of user I imagine most people participating in prediction markets are. It's telling that the vast majority of the people making bets lose their money. Are their predictions really valuable data?

It's telling that only recently the CFTC has discovered such authority. No previous leadership of the CFTC read the act to mean what the current leadership thinks it means.

Have you heard of Betfair? A UK company which has done "prediction markets" since 2000. In the Europe it is called a betting exchange and regulated like sports betting. And betting pools is another form of betting which is way older than that and there are no house in them either.

And by your argument poker or backgammon would not be gambling either.

> there seems to be no upside whatsoever

There's the same upside as pretty much all other forms of gambling. Plenty of people enjoy it and it can be used to generate tax revenue for the state.

Don't get me wrong, there's tons of harm that can come from it, but the arguments to allow them are essentially the same arguments for allowing sports betting.

kube-systemabout 23 hours ago
This is true, however many of those arguments are weaker when applied to things for which the outcome is more consequential than the outcome of a sporting game.
superfrankabout 23 hours ago
Sure, but that's not really an argument to ban prediction markets, it's an argument to regulate what the public can or cannot bet on.

Most major online sportsbooks have taken bets on the US presidential election for well over a decade. I can't imagine anyone really arguing that it's okay for DraftKings to offer that market, but not okay for Polymarket to offer it.

I put it somewhere else in this thread, but there are actually two different questions that need to be answered separately. Are prediction markets just sportsbooks by another name and are there certain things that we should not allow people to gamble on.

The argument around prediction markets always seems to squish those two into one which I think does people who want regulation a disservice. I think to most people, the answer to first question (are prediction markets just sportsbooks by another name) is a pretty resounding yes. The second question has a lot more room for debate though. Even if people agree that there should be things we don't allow people to bet on, there's still plenty to argue over where we draw the line. The problem is that as long as we mush these two together, people will use the disagreement over the second question to prevent action from being taken on the first.

Commodities futures markets on which what are traded are contracts for future delivery of goods do that.

Prediction markets—forums for gambling on the outcome of a platform-provided referee as to how a proposition about the future will be resolved—do not do that at all.

Now, the legal definition of commodities markets for regulatory purposes in some jurisdictions may be broad enough that prediction markets are legally a subtype of commodities market despite doing a very different thing than traditional commodities markets, but that’s an artifact of a legal definition being drawn in a very broad way at a time when it didn’t matter because nothing like prediction markets existed.

Those markets create pressure to ensure that real physical goods and useful services are priced accurately. Prediction “markets“ are in my estimation no different than roulette.

If you cross your eyes hard enough, you could claim that roulette gambling provides economic pressure to ensure that roulette wheels are balanced evenly. But when the roulette wheel is Vanah White’s dress color, what does that mean? Charitably, it’s a fun pass time. Through a dystopian lens, prediction markets pressure all public figures to play a kind of Keynsian Beauty Contest with their own behavior. Like social cooling for the celebrity/owning class.

kibwenabout 24 hours ago
No, this doesn't work. Predictions markets can only resolve to things that are publicly verifiable, so any leaked information is information that was destined to become public anyway. Furthermore, the leaker is disincentivized to leak in such a way that the act of leaking could compromise their insider knowlege; the structure of the markets means that leakers don't want you to have this information in any way that opponents could usefully invalidate.

They're just gambling. I'm not trying to argue for or against gambling here, but please stop trying to delude yourselves into thinking these gambling sites are anything other than gambling.

Information aggregation is the theoretical upside of prediction markets. Granted, their effectiveness in that role is an empirical question. For gambling in general, the upside is that people obviously enjoy it, not to mention the right/freedom to make choices about how one spends time and money as a responsible adult.

If harm to the consumer and societal burden are the downsides you're concerned about, you could justify banning smoking, alcohol, and junk food for the same reasons. We don't generally do that because we recognize that where there's demand there will be a market, whether it's legal or illegal. So you also need to weigh the potential harms of a black market against those of a legal and regulated market.

I think in 10 years we'll see the rise of online sports betting, including in prediction markets form, as a new opioids epidemic.

For some amount of people they use it recreationally to blow off some steam, but theres a segment of the population that ruins their lives on it.

In some sense it may be worse than opioids because a husband (its always the guy) can ruin their families finances in secret before the wife's credit card gets declines & she pulls on the threads to find six figures of hidden debt from it and realize they are about to lose their home.

In some ways, historically having gambling located in specific geographic areas that were not within most peoples daily travel routine ensured safer use.

One of the biggest commodity trading companies is in Minnesota (Cargill), where I would think that commodities are a prediction market too: They predict the harvest and relate that to a future price.

No, a stock is a share of ownership in a company.

Now yes, people bet on the derivative value of those ownership shares... but that also happens to basically every asset. If a stock is a prediction market, then so is corn, and gold, and your home.

michaelscottabout 23 hours ago
Yes, they are. Accurate prediction is rewarded in every market, for every asset or asset class. There are adjacent order benefits (I live in my home, I eat corn, I have a say in how a company is run) but these are never divorced from the impact of prediction and prediction in aggregate is just a crowdsourced leading indicator of value; oil spikes the moment a missile hits Iran not because the 2 are explicitly linked, but because the market has predicted the effect on the flow of that oil over some subsequent timeframe and priced itself accordingly
kube-systemabout 22 hours ago
Yes, but all of these things have underlying assets that are not themselves predictions. You can buy and sell corn commodities, but at the end of the contract, actual corn is delivered. Predictions markets are different in that they betting on the prediction itself and have no associated asset.

The difference in my mind is that prediction markets and gambling are betting on outcomes, not long term behaviors. You could make the argument that they are the same, in the sense that buying a stock is "betting" on a company to do well, but I think you'd be making a silly argument. Stocks are intangible these days, but they were traditionally a physical thing that one would trade. If you're betting on prediction markets, there's nothing to trade after the event happens, just payouts.
SoftTalkerabout 24 hours ago

abustamamabout 16 hours ago
The stock market by itself has similar outcomes to the prediction markets (you buy X hoping it'll go up so you can earn $Y), but there's actual value being purchased. If I buy an apple stock, I own 0.001% or whatever of the company. If the company goes up to $10T in value, my little share is a percentage of that. I can sell it and be happy.

If the company goes to $0 then I own a portion of nothing, and so does everyone else who owns a share.

With prediction markets you don't own anything, and regardless of the outcome, someone can still win if they "bet right"

That said, futures and derivatives seem similar to prediction markets but I don't know enough about them to say more.

I don't watch Twitch, so I was blown away that they allow that kind of thing on their platform. The cherry on top is that he runs some kind of fake gambling extension in his chat while he's streaming, where viewers bet on how much money he'll win or lose and they'll win or lose Twitch chat points alongside him.

Remember in the late 2010s when the hack Ajit Pai, then fCC Chair, said that the FCC couldn't or shouldn't enforce Obama-era Title 8 net neutrality? Remember how states like California then said "OK, it's not a federal issue so we'll do it at the state level"? Then remember how the DoJ, at the FCC's direction, sued California [1]?

Well, which is it? Was net neutrality a state or federal issue? The answer is it's, as always, a Schrodinger's STate's rights issue. That is, it's a "state's rights" issue when it suits them, a federal issue when it suits them and it's neither when it suits them. Lack of any kind of regulation is the goal. This isn't some libertarian pipe dream. It's just naked pro-company and pro-billionaire gutting of government to boost profits.

Fast forward to prediction markets. The CFTC regulates this (arguably). Another deregulation hack is in charge. And again, states like Minnesota who already ban sports betting are being sued. "State's rights" btw. We're seeing the exact same pattern.

This on the same day that the president who sued the IRS, which was defended by the president's DoJ and the recess appointee Attorney-General settled a $10 billion lawsuit right as a federal judge tosses it because the case lacked adversity [2].

Besides the J6 slush fund, part of this settlement is that the IRS is barred from ever investigating Trump, his family or the Trump Organization for tax fraud.

The level of corruption and kleptocracy here is beyond belief and what's really frightening is that a good 35-40% of the population not only don't care but actively support something they will never benefit from and there hasn't been (and won't be) any political price paid for any of it. The president's endorsement still carries weight and just today, we've had the most expensive Congressional primary in history (~$35 million) where Trump unseated a sitting Congressmen for daring to push for releasing the Epstein files.

But that's highly contingent on that thing being something people are willing to violate the law over, and on the convenience of that thing not being significantly impacted by prohibition. Neither of which are true for prediction betting (it's almost identical to sports betting in that regard, imo.) The only reason these markets proliferate is precisely because they are legal.
