I would not be surprised if people are murdered at some point to reap the payout of some related bet.
It also incentivizes leaks from insiders, sometimes endangering others. A soldier was charged for betting on a military operation. https://www.justice.gov/opa/pr/us-soldier-charged-using-clas...
And of course throwing pro sports, but that's been happening for ages. Sports has always been crooked: eg the Eupolus Scandal from 388 BCE.
‘Hairdryer or lighter?’: French police look at claim of sensor tampering to win weather bets

That would have been perfect.
It's bad enough when such systems fail due to whatever sort of issue, but the last thing aviation needs is people intentionally blowing holes into the swiss cheese security model -.-
> You aren't allowed to set up a life insurance policy on someone else's life, or a fire insurance policy on someone else's home
This isn't really true. Lots of people take out life insurance on others as a hedge for many reasons, small business partner is one. Same fire insurance, we had a case where someone pledged a building as collateral and we took out separate fire insurance on the building so we'd get paid out immediately.
I'm not sure where this false premise started but alot of people believe it.
This is done because the insurance company wants you to prefer that the covered event doesn’t happen, which avoids some conflicts of interest.
These prediction market events don’t have the usual insurance interests involved.
You're not allowed to take out life insurance on someone you don't know or have a relationship (business or otherwise) with.
Life insurance on a business partner works. Life insurance on your spouse as well.
Life insurance on the leader of a random country? Unlikely
It being the driving plot behind Double Indemnity probably started it. I always thought it was true until your comment, too.
If you wanted to correct a misconception, you should provide a better, more complete understanding, not just express frustration about a misconception that doesn't even exist outside of an uncharitable reading.
In this case, that means refining the point to the more accurate model, that you need an insurable interest -- i.e. reason you don't want the event to happen, even knowing you'd get a payout[1]. Your counterexamples only work as such because that exists![2] If you want to fix all the people who don't have your superior understanding, that would have been a great way to help them out.
>I'm not sure where this false premise started but alot of people believe it.
It exists because it's approximately true: you can't get insurance on 99.99999% of buildings in the world because you have no insurable interest in them. And any time someone could correct that false premise, they probably just complain rather than providing the complete understanding -- exactly the choice you just made here.
[1] IMO, this is the natural dividing line between gambling and insurance https://news.ycombinator.com/item?id=13916088
[2] Edit: And in your building collateral example, the policy would prevent you from double dipping -- getting both the building and the full payout.
To be clear they had explicitly written in the contract from the start that death didn't count. And they paid out the full amount - just not to the same betters they would have if he had left office alive.
You can sell your life insurance policy to somebody else. It's a way of getting money to sick people to use while thy are still alive.
Polymarket is facilitating bets between people, not bets with the house. Gambling and insurance are both bets with the house.
What jurisdiction are we painting with that broad brush? This is far from universally true, even in the US.
Yes, there are de minimis exceptions. Your office NCAA pool, for example, is often legal, but it has nothing to do with what we're talking about and is also irrelevant to a business facilitating it via 18 U.S.C. § 1955.
A bet is a bet, whether it's against the house or other people it's a bet.
Any bum defending these contracts is to me either a shill or way too dumb to understand the concept of incentives.
Oh and there was an Israeli journalist that got life threats because he reported that an Iranian missile struck some place in Israel, and apparently there was a huge bet on it on polymarket.
I would argue that the ratio between "power" and "money to be won" is too big (at least right now) for this to materially matter. No fortune 500 CEO is going to postpone a product launch so they can win $5,000 on polymarket. But some random guy will get his hair dryer to win a socially meaningless weather bet.
It's not discussed often, but the liquidity of these markets is often awful, and you can only win as much as people are willing to take the other side. Which is harder when people know it's easy for insiders (or the outcome decider themselves) to play the other side.
Basically the more socially consequential the outcome you control, the less likely you care about a betting market, and the less the betting market cares about you.
The real winners are people with little or no power to effect outcome, but with insider knowledge. And athletes.
No, but a low paid frontline worker with the ability to throw a last minute wrench into the gears absolutely would.
Usually though people's pay/power directly correlates with how badly they can screw the company if they go (legally) rogue.
But anyone can get a job at XYZ, buy puts, and go and set the factory on fire the next day. Betting markets don't change the fact that you'll be arrested, except that you'll be arrested for a few thousand dollars rather than whatever you can squeeze out of options.
You're basically arguing that there aren't enough fools to go around, when we're talking about gambling enterprises.
Welcome to the grift economy, take a number.

If I find out my friends placed bets on whether I'll say X tomorrow, I'm not obligated to act as if I didn't know.
They would win a lot more than a trivial amount by taking adverse positions, no? Seems like you're making up your own hypothetical
Think of it like kids betting pennies what subject the teacher will open with the next day. The teacher doesn't care about winning $0.89, but the kids do.
There's plenty of people able to influence events to whom these barely liquid bets can still amount to huge pay offs.
That includes many CEOs whose compensation is tied to stock performance.
Single moms historically don't have tons of extra money, and Trump was ostensibly a billionaire.

Its a small step from betting on ships sinking to making sure they go down.
In 2017 someone tried to bomb the bus of the BVB soccer club, after he bought puts options on the BVB stock.

What you describe (profiting from creating havoc by some "short" bet) is indeed problematic and is regulated.
This is also one more reason why trading should not be unconditionally anonymous. Another reason: proper trading venues have rules against "squeezing", namely that no entity may hold more than some threshold ratio of the open interest. That's obviously impossible to enforce with anonymous markets.
[1] Tradings allows individuals to time-shift consumption, it funds productive enterprises, it incentivises convergence of market price with fundamental value, which in turn is what enables efficient investment allocation, and it allows the emergence of an economy-wide equilibrium of savings and investments. Note though that all of these functions might well be fulfilled by having, say, one minute of trading a day.
This happens on the stock market on a scale 100x larger than Polymarket.
c.f. manipulated earnings reports, taco trades, strait of hummus nonsense
How does the same line of argument not also suggest that stock markets be prohibited?
Do you really think that there are no people, who have bet on the price of something in one direction or the other, who enact real world consequences on people or other entities in order to ensure their bet? This is par for the course.
Legislation by who is willing to "donate" the most; law of the jungle capitalism.
Thanks, stranger!
Let's not pretend that Spain of all places is caring about horribly destructive psuedo-gambling.
Banning "unregulated gambling" is just pressure to make sure that the Spanish gambling racket stays intact for the bookies already at the top.
Is this intended to imply that Spain has particularly high levels of sports betting, or issues with gambling? All the stats I can see suggest the opposite, and there's already plenty of tight restrictions on local gambling businesses (sports sponsorship ban, welcome bonus ban, almost no public advertising, etc). At a quick google, it looks like the 'Spanish gambling racket' for sports is tiny, gambling problem stats far lower than UK/France/Italy, and most gambling that does happen is the lotteries etc instead, which has its sins, but is a very different beast.
Is there something specific you're getting at?
Not a fan of lottery myself, but at least it's just some random numbers drawn from a drum. There is hardly any dark pattern or illegal incentive there. It is just you against Thomas Bayes.
La Quiniela, a lottery based on soccer matches' results. Every middle aged man filled some weekly forms (win for locals/draw/win for foreigners) as if it was a religion. If you matched 14 from 15 results (much better with 15), you could get a big prize. Also, Jai Alai matches on the North of Spain had huge bets on results too.
Younger millenials and Gen-Zers will just play on RETA which is kinda the same as La Quiniela but online.
I would replace them with https://manifold.markets/ or maybe heavily regulate them. they do have practical utility in forecasting
> Play money means it's much easier for anyone anywhere in the world to get started and try out forecasting without any risk. It also means there's more freedom to create and bet on any type of question.
Their investors/lawyers probably did not want to back the risk using real currency adds.
And don't forget about the kids and what possibly could happen maybe someday!
Polymarket is quite tame in comparison, in my opinion.
You can also follow people. Tax fraud is how a lot of criminals are caught - we don't know what you did but we can prove you didn't get the money legally and that is enough.
These markets decentralise that information asymmetry.
How do I cause someone to die using Kalshi or Polymarket, specifically, also without being caught? Didn't they catch someone that had pre-knowledge of the Venezuela campaign?
(I'm not asking because I want to do this, I'm asking because it's not clear to me how this is realistically possible.) Also, given that you can't just create a market on either platform, it's not like I can just say "XXX has 3 months to live".
If a criminal wants to make money on crime, they have better ways to do it than put 10k of their own money to make 50k by killing someone.
I just don't get this whole argument. If you're a contract killer, why put yourself and the contractee up in the feds sights?
Assuming you get away with the murder, guessing that's not the part you're asking about, a concrete example: https://polymarket.com/event/next-french-presidential-electi..., bunch of people on that list, surely many of them are like the typical European politician, mostly without assassination protection most of the time. Place a "No" bet on one of them, then hire someone to assassinate, and Polymarket indirectly drove someone to murder another person, as they could profit from it.
As a contract killer, I don't think you'd put yourself or your client more up in the fed sights than without Polymarket, it'd just look like another bet.
This is the same reason it is generally illegal to make public statements lamenting that someone hasn't killed a person.

I don't know if a contract is a good way, but it gives some deniability.
The astute observer might say "ah but what about crypto gambling sites like Stake?". This problem isn't as intractable as crypto bros might have you believe. You simply issue arrest warrants for people who allow your citizens to gamble in violation of your local laws and you threaten any bank, brokerage or financial institution that allows them to convert their crypto in fiat currency. This is fairly easily covered by KYC/AML regimes alreaqdy. It won't be perfect. It doesn't have to be. As soon as someone can't be an open billionaire by selling crypto gambling without fear of being extradited to the US if they travel internationally, the shine disappears real quick.
Sadly, from my point of view, you're right that right now going after the on/off crypto ramps would be enough to dissuade most people from using crypto gambling sites. I hope for a more educated populace that can bypass these laws and engage in whatever consensual activities they want to, as long as they're not directly harming anyone.
- incentivize harmful acts - create manipulation risks - are "contrary to the public interest"
So, all these contracts on the topics of US attacks, sports, whether California will burn due to fires, openly violate it.
But CFTC's head has publicly stated that they won't act on them.
Do you think regulation of all possible categories of people who could behave adversely to influence prediction markets would be preferable to just regulating the market itself?
Sports betting places on the other hand have multiplied like fungi in the last two decades, unfortunately.
Allowing prediction markets to overlap with criminal incentives is a platform TOS and moderation problem; not a prediction market or betting exchange problem.
What in the fuck are you talking about? This is a public policy problem and has been literally for 3,000 years.
It's one of the oldest and most pervasive public policy problems that has spanned nearly every culture that's existed since there was culture.
The language is usually "This market will resolve to “Yes” if <politician> ceases to be <Prime Minister/President/whatever>".
Or for another example: https://polymarket.com/event/will-neymar-play-in-the-2026-fi.... Will Neymar play in the world cup? Not if he's dead. Any kind of "will celebrity appear in X in the future" can be reduced to an assassination market.

Not sure if Polymarket does the same. Also not sure if I really trust these people to be the arbiter of morality and adhere to their own rules when it doesn't benefit them.
In other words the money spent on bets that involve killing directly foments more killing.

It's not at all obvious that leaks of classified information are per se detrimental to _actual_ national security.
We experimented with extending this to non-esports topics during the election, which led to a bunch of Trump-based predicting. Then Jan 6 happen and the whole site went to hell. I pivoted the product because I just didn't want to deal with running a site like that.
Seeing what is happening with these sites makes me feel good about my choices. If I were in charge of a product that enabled this I wouldn't sleep at night.
There are the people from the kill command who bet on what they are ordered to do.
There could even be a bet by someone with direct influence on the government who convinces them to do it to make some money.
Fortunately we have big beautiful crypto that separates us.
Just naming things differently does not work in other countries.
If it quacks like a duck, swims like a duck, and looks like a duck, then it probably is a duck.
Now they encourage users to bet as part of the commentary.
I see the percentage of advertising devoted to gambling to be a similar bellwether to the decline of my whole country. And it’s getting worse all the time. I can’t turn on the tv, look at billboards on the freeway, watch a sporting event, or even walk down a supermarket checkout without getting constantly reminded of how far we’ve fallen.
https://closingline.substack.com/p/the-takeaway-kalshi-non-s...
gambling happens, tax comes in, crime goes up, police get hired, politicians get the police vote
Kalshi and Polymarket require you to provide your SSN.
It doesn’t make sense that if I bet on the outcome of a football match then it’s gambling but if I bet on the outcome of the Ukraine war then it’s I-can’t-believe-it’s-not-gambling.
What is the defense in the US for example that these are not gambling, "bets are placed on uncertain outcomes", it's that close to, if not the definition of gambling ?
So where is the line drawn? In the US there has been a tremendous amount of money spent on lobbying to keep prediction markets on the not gambling side.
I'm sure you need a license to become an insurance broker, stock broker, commodoties broker.
Gambling license is all they need to get.

Prediction markets are also regulated by the CFTC as they're futures contracts technically.
Not really how it works in practice here, some Cloudflare IPs are unavailable for a few hours, everything mostly keeps working as it always is.
Spanish congress approved recently a way to stop such a thing.
It's like calling the casino a probability market.
(Which of course doesn't make it any better or less of a casino, this is just to say that the word market didn't come from nowhere)
I think you might be mistaken about how Polymarket works. They are indeed only a platform operator; all trades are directly between participants.
For example, I had a lot of people ask me about the Hantavirus and if it was worth worrying about. I didn't have to do any research other than look at the various prediction markets and see them all at 5-10% to determine it was probably a nothingburger. Much quicker than having to parse a bunch of fearmongering news reports and such.
Why a ministry has the authority to do so? What I don't like about my country, and the whole UE, is the lack of democracy. And this is a good example.
A democracy needs to have real separations of powers. The legislative body creates a law, and the judiciary, based on that law, will decide on banning or not the online gambling site.
A ministry belongs to the executive branch of the Estate. It is not up to them to decide whether something is illegal or not.
The law was already there, a minister in Spain does not only propose or vote on laws, but has quite some executive influence. This has always been so and is nothing unusual.
You can't really operate this stuff in a vacuum, otherwise it would take years to take any actions against illegal gambling, way too late.
If a law is violated, then a judge, and not a ministry, should be the one to enforce it.
When an administrative body blocks access to a service without prior judicial oversight, it blurs the line between the executive and the judiciary. And since separation of powers is a key component of any democracy, this raises legitimate concerns about the quality of democratic checks and balances.
Just to be clear: I’m not arguing that unlicensed online gambling sites should remain accessible. The issue is how the restriction is carried out, and whether it respects democratic principles and institutional roles.
I could be pretty neutral on the market maker, really. The point of a prediction market is to put information to use.
There may be some line to be drawn on such markets, but that line really isn't drawn. There are just vague gestures that it is both gambling and not gambling due to insider information.
If you wanted to regulate it, legislate which markets can be made. Require notification that it is not gambling and is all about the trading of insider information and that gamblers have less than "fair" odds.
I can't make this argument work at all. Gambling with some cheating is still gambling.
Complete shamelessness all around.
Imagine your neighbour the alcoholic gambling addict having to learn to use cryptocurrency and VPNs and then having to file taxes in case any substantial winnings (from illegal gambling)...
It's important to remember that ~80% of activity Polymarket and ~90% of Kalshi, by volume, are sports. These are effectively sports betting websites with prediction markets on the side.
I mean Spain blocked these markets for now, to investigate how to deal with them, I don't think it's for sure they'll be classified as gambling and allowed, might very well be outlawed. Probably parent got confused you said "The whole world will eventually do the same" (about blocking/banning) but then seemingly you thought these were "classified as gambling" already.
It not until recently ISPs got asked to do blocks by IP, as Cloudflare wasn't responding to legal takedown requests, hence we currently seem to experience both types of blocking, but the IP-based blocking happens a few hours per week, the other ones are permanent.
Betfair doesn't present itself as anything other than what it is: a gambling exchange where the punters make the book. In my 10+ years time of using it they despite some occasionally shoddily worded markets they have only properly screwed up a market twice (The Australian Open in 2022 when Djokovic was denied entry to Australia and Betfair basically forgot the winners market was cross matched when they went to remove him and the 2020 Presidential election where they suspended the market when Trump went to hospital with Covid despite the fact the market rules said that the market would still settle if any participant died and obviously most people had been taking into account that both candidates being mega ancient whilst a global pandemic was happening might be a factor). Betfair is boring, staid and reliable.
Compare that to Kalshi and Polymarket who do everything they can to pretend they are not gambling platforms. It's kind of gross.

I think that self fulfilling prophecy attempts by deep pockets trying to sway markets by bucking trends generally transfers money from more to less foolish bettors.
Why are the sports odds useful? Word mention market and sports market are the majority of bets after all. Seems like >90% of wagers are useless noise.
Name 7 recent useful ones you actioned based on, one for each day of the last week. I’m very curious what those may be that you use it daily.
When I looked a the site and checked out a few non sport/word wagers, the actual bets were pretty unhelpful because while their summary sounded potentially informative the actual fine print showed that a weirdly constrained timeline of a specific thing was the actual deciding factor, making them useless.

One issue is that prediction markets provide financial incentives to perform actions in the real world. For example, if I want a head of state murdered, I can wager lots of money that they won't be murdered. If somebody wants to earn that money, they can simply bet against me and then murder them.
It's not an dispassionate wager like betting on roulette, it's a wager that directly influences the real world, at least a bit.
Of course you could directly hire an assassin, but that doesn't come with plausible deniability.
