The linked article is pretty interesting:

> found a pattern of [Polymarket] sharing false and misleading information

https://www.nytimes.com/2026/03/20/technology/polymarket-soc...

They don't have much to say about Kalshi other than "unlike real mainstream journalism, there’s no accountability". Which isn't saying much, because nobody is claiming prediction markets are a type of journalism.

Journalism is one particular way of trying to learn about the world. Academics are another, the scientific method is a third, and so on.

Claiming that something is a better way to learn about the world is NOT the same as claiming it is using a specific method, or part of a specific tradition.

I’m open to being convinced, but if you’re claiming mainstream media has no accountability, I think you need to substantiate that.

I realize there are information bubbles on the internet where this is accepted as truth, but unexamined. Nonsense is everywhere on the internet. I’d be curious how you’d substantiate this.

Insider trading is legal in commodities markets. If I am engaged in a hedging transaction I am doing so because I know about risks that I want to offload, and the buyer does also. You don't come to commodities markets without information.
gavinsyanceyabout 3 hours ago
Hedging is not insider trading. Insider trading is trading based on material non-public information in breach of a duty or obtained through fraud. In that sense, it's more of a principal-agent problem.

Also -- hedging is generally not done based on material non-public information, but rather to guard against known risks. Joe the farmer sells a bunch of wheat futures when he plants his wheat, not because he thinks the price will go down, but rather because if it does he goes bankrupt and he'd prefer to accept a known rate-of-return now.

Note that's a US definition — Europe is stricter and draws the line at non-public information [0], aside from certain carveouts and safe harbors. Matt Levine describes this as "theft" (misappropriating nonpublic information) vs. "fairness" (using nonpublic information at all) — iirc if you're on a flight and overhear a passenger in business class talking about an upcoming merger they're working on, that's legal to trade on in the US but illegal in Europe. At least that's what I generally remember about "parity-of-information" theory.

If you and the buyer know about the risks then you’re not making a trade based on material non public information, are you?

If you make a hedging trade while having material knowledge that you withhold from the counterparty… well, that sounds like it could be edging towards fraud. Like taking out life insurance while hiding a medical condition.

But sure, it’s not against the law to do business with a sucker, so there’s degrees here.

CPLXabout 3 hours ago
Just for context that’s not quite accurate. There certainly is a distinction in the rule versus securities markets, which I know is what you mean.

But it’s more accurate to say participants can trade on lawfully obtained material nonpublic information absent some independent duty not to use it, which is much narrower than saying insider trading is generally legal.

Exactly. Pit mine sees who's buying what and is worried copper will go down. Datacenter people see who's inking deals and are worried it's gonna go up. They both need to get big fancy loans from their bankers to execute their upcoming projects. The bankers won't like to see unbounded risk on their balance sheets. A futures contract exists to solve this problem.

Not that this excuses some of the absurd stuff that goes on on the online betting platforms...

I hate prediction markets but simultaneously find this a little rich.

I think most people have experienced what Michael Chrichton called Gel Mann Amnesia - the idea that newspapers feel accurate except about topics you know about.

Whenever I read about topics I know about: such as my employer, a political topic I am particular familiar with, etc - the reporting is usually off in what MC called a "wet streets cause rain" kind of way.

I haven't seen any accountability for this kind of reporting. If a newspaper wrote that someone was born in 1980 but it was actually 1985 they may correct that but the broader theme of articles being inherently misleading to reality is rampant and I suspect significantly worse than when MC conceptualized this problem.

That's to say I am not sure there's a practical standard to which a random times writer is held that kalshi isn't to. If anything I think kalshi is more clearly presented as "a bet" vs "the truth" so I don't understand the meat of the grievance.

A great irony here is that Kalshi and media generally are competitors. When I make important decisions (e.g. understanding politics, where to travel and setup companies), I always value betting markets over hearsay (aka media). The former has real money at stake, whereas the latter often has no skin in the game (as well as a other issues; like herd mentality, sensationalism, incentive to tell people what they want to hear rather than what's true).

kevinwangabout 1 hour ago
obviously and definitely true in their current form. But it's maybe worth clarifying that before this last year or two, when Kalshi became an obvious regulatory dodge (including adding sports and really leaning into the gambling demographic), many were interested in prediction markets not just for that purpose: e.g. the rationalist community seems to have had a longstanding interest in the idea, manifold didn't have real money, and predictit (which is like a decade old) had academic origins.

As a tangent, it reminds me a bit of cryptocurrency: in the earliest days the interested parties have a mix of intellectual (can it be done? How can it be done?) and some idealistic (this technology will have utility, like reducing spam or libertarianism for crypto, or giving us a more accurate and precise understanding of the world for prediction markets) values. Of course, as both are directly financial, the third value is that one stands to get rich off of the technology. This third value might be adequately communally suppressed in the beginning, but the force of money gradually makes this third value the only one that matters, and both technologies become net-negatives on humanity.

The stock market isn't fundamentally a gamble. Spending money to buy a share of a company's future dividends is a sound way to invest money and earn a return on it.

The problem with the stock market is when there aren't enough new companies going public to soak up the spigot of all the capital that people want to invest, leading average P/E ratios to increase over time. There is too much money chasing too few earnings. When the underlying fundamentals don't match up, then all that investors are doing is speculating that someone else will be the bigger fool and buy from them at an even more unreasonable price - and that is a gamble.

In 2018, the US Supreme Court said the federal law preventing it was illegal.

https://en.wikipedia.org/wiki/Murphy_v._National_Collegiate_...

It was banned by the federal government in 1992 by an act of Congress (with bipartisan consensus and signed into law by a Republican president). The supreme court vote overturning it was also 7-2, with 2 of those 7 appointed by a Democrat president.

orangecat34 minutes ago
It was banned by the federal government

Not exactly. The law was weird, and that's why it was overturned. It didn't make sports betting illegal federally, instead it prevented states from "authorizing" it, which the petitioners argued was an unconstitutional intrusion into the lawmaking ability of states in that it prevented them from repealing laws against sports betting that they had previously passed.

The full ruling is at https://www.supremecourt.gov/opinions/17pdf/16-476_dbfi.pdf, and the last paragraph sums it up: "Congress can regulate sports gambling directly, but if it elects not to do so, each State is free to act on its own".

The SCOTUS ruling didn't legalize sports betting; states chose to do that themselves once they were no longer prevented from doing so. Congress could ban it nationwide today, and probably they should.

Unfortunately, this shows how much facts and reality have been turned into nothing more than a loyalty test by both sides of our political debate.

> A partnership between The Times (for The Athletic) and Kalshi would also provide validation that their prediction market data should be taken seriously as an indicator of the future. Facts prove otherwise.

They could have objected to the partnership on any number of valid grounds, like the fact that predicting the outcome of sporting events provides no valid benefit and can only ever be gambling, or that the integration is probably going to be pretty lame and provide no benefit to the reader.

Instead, they felt compelled to make a trivially false claim, the claim that prediction markets do not accurately predict the future. It's trivial to prove that this claim is false, because if it were true, it would be very easy for anyone to make a huge amount of money on prediction markets.

It's even more telling why they made this claim, to avoid "providing validation". Not because of any harms caused by sports gambling addiction, but because it could provide a tiny piece of political ammunition to a product that has been slotted into the opposing political tribe. Reading this statement, one gets the impression that they would be completely OK with sports gambling on The Athletic, as long as it was provided by a more traditional casino-style bookie operation.

I'm guessing that anyone in the room when this statement was written who even brought up the question of the facts could be safely sidelined and ostracized by the union as being insufficiently loyal to their political position.

I'm not intimately familiar with prediction markets (I avoid gambling), but can you explain how this is the case? If the market unpredictably incorrect, then shouldn't it be difficult / impossible to predict precisely which bets will be wrong in a way that would allow you to profit from them?

Ultimately isn't it the case that all they're doing (at least from a prediction point of view) is aggregating (better or worse informed) guesses? Excepting outright corruption / insider trading of course. This might tell you a great deal about what the set of users of a given prediction market expect as an outcome for a given prediction, but it doesn't tell you anything about the future itself. Any more than the stock market (fails to) tell us to pull out money out the day before a crash.

I think a good toy example here could be a market on a coinflip. Let's say heads pays out $1 and tails pays out $0, and people can buy and sell contracts that resolve this way. Naively, people might think that this is a 50/50 outcome, so if anyone wanted to buy or sell this contract for some reason, they'd likely be able to find someone to trade with them around the price of 50 cents.

Now, say that you somehow knew that this coin wasn't a fair coin, and instead was weighted 55% to fall on heads, 45% tails. Then, you would be happy buying these contracts for 50 cents -- given the contract pays out $1 if the coin lands on heads, and you know there's a 55% chance of heads, the expected price for the contract is 55 cents, and you make 5 cents in expectancy.

So, if you had information about the "fair value" of this contract, telling you that the price should be 55 cents, you'd be incentivized to buy the contract at prices below 55 cents. If the contract was trading at any price other than 55 cents, then, from your perspective, the price would be incorrect. And if the price is incorrect, then you'd be able to make money trading: buying for prices below 55 cents and selling at prices above 55 cents. And finally, as a result of your trading, you'd provide one-sided demand to the market, pushing the price closer to the actual correct price.

From this simple mechanism, wherein everyone who has information is incentivized to make money on their information by trading, prices start getting pushed to accurately reflect the aggregate of the information that everyone possesses! So in markets, there is a profit incentive to provide information, and this makes prices more accurate.

Finally, I think a common misconception is that prediction markets are sometimes wrong, as events priced at low probabilities sometimes happen. For example, in the 2024 election, Trump was trading at probabilities below 50%, but he still won! However, this is conflating present information about the future with future results. Given the earlier example about the biased 55% coin -- before we flip the coin, the best thing we can possibly say about the future really just is that there's a 55% chance of heads and 45% chance of tails. If we then flip the coin and it lands on tails, that doesn't mean we were incorrect -- it was just the best statement about the future that we could have possibly made.

Prediction markets -- or really any price system -- aggregate the best available information about the future. If you can confidently state that they are wrong -- that their best available information about the future is inaccurate -- then you should be trading and making money.

Does that clear things up a bit for you? It's a longer response, but I think it might address some of the confusion that you (or anyone else) might have regarding what people actually mean when they say that these prices predict the future.

Christ, just say you are conservative and don't like unions and their political stances. 'Accuracy' doesn't matter at all when it comes to assessing harm, but the existence of a market signal itself can change outcomes, and then much vaunted 'accuracy' becomes a mechanism for fraud in a new and different way.

Even taking your nitpick a little bit seriously, behold:

> Retail prediction market traders pick winners 51.3% of the time yet lose money; automated traders achieve coin-flip accuracy yet earn $133 million.

The entire enterprise exists to move money from gamblers to companies. The externalities (suicide, social degradation) of this transaction is bourne by society.
