These - especially Polymarket - should be illegal globally, as they incentivize people with power to manipulate the real world in horribly destructive ways to win a bet.

I would not be surprised if people are murdered at some point to reap the payout of some related bet.

imglorp2 days ago
Very close already. Death threats went to this journalist; seems someone bet on missile hits. https://factkeepers.com/polymarket-gamblers-vow-to-kill-jour...

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.

Oh man, I thought from the headline that it was going to be about a new prediction wager on the site about whether the manipulator had used a hair dryer or lighter.

Whoever did that deserves a few years in prison. Normally I'm not too much of a friend of draconian BS - but accurate reports of temperature, air pressure and wind speed are incredibly important for the safety of air travel.

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 -.-

It also substantially changes the definition of who's an insider. Polymarket has bets for random things like a particular word being used by an announcer. Suddenly the announcer is an insider on that bet.

I don't understand why people would want to bet on such an easily gamed outcome. I can understand that some people are compulsive gamblers, but it seems such a foolish thing to bet on. To me, it'd be like betting with someone about how many fingers they're going to hold up.

People sometimes do drastic things when they experience large gambling losses. They might embezzle, rob, scam, be unable to pay rent or debts. It has a significant effect on people who are not directly involved in gambling.

Yeah. 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. For obvious reasons. But buying an event contract that pays if someone dies or someone's house burns down is fine?
chollida12 days ago
being pedantic here but

> 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.

compiler-guy2 days ago
The technical term is that you must have an “insurable interest” in what you insure. Both of your examples are people protecting their insurable interest. Ownership is the most common insurable interest, but there are many other ways to have one.

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.

mschild2 days ago
To perhaps be a bit more pendantic.

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.

SilasX1 day ago
Yeah, you are being pedantic. The clear meaning is that you're not just allowed to insure arbitrary properties.

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.

loeg1 day ago
Some of the prediction markets explicitly forbid payouts based on death. E.g., Kalshi refused to pay out "leaves office" when Khamenei was killed.
gpm1 day ago
> Kalshi refused to pay out

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.

There are a lot of things short of death that we don't want to encourage either. There is a huge grey zone here that I frankly don't want to entrust to private entities.

Well, you are privately allowed to bet on whatever you like with another individual. That is indeed legally fine, though potentially distasteful.

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.

jubilanti2 days ago
Nope. "We're just an intermediary between people" is a 100+ year old yarn that casinos and bookies have been trying to spin. If you're presenting a point of entry to a betting line and taking a cut, congrats, you're the house. Doesn't matter if you adjust the betting line manually based on intuition or algorithmically based on betting volume. Sometimes it doesn't get enforced because of corruption, but if this was the case, then why aren't there tons of independent unregulated poker casinos where players just play against each other? If you facilitate and take a cut, you're the house.
CPLX2 days ago
What the hell are you talking about? You are absolutely not allowed to bet on whatever you'd like with another individual. Depending on what you're betting on (for example, the price of a stock or the throw of a card), it falls under varying different regimes. This is highly regulated and has been for most of the whole of human history.

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.

> as they incentivize people with power to manipulate the real world

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.

jubilanti2 days ago

No, but a low paid frontline worker with the ability to throw a last minute wrench into the gears absolutely would.

WarmWash1 day ago
They can already do this easily with the stock market.

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.

They can take any position they want and do whatever they want, the point is that these oddball markets are very thin so there just isn't much money there to harvest. You can only bet $50M at your chosen risk if you can find enough people to take the other side, and these markets simply don't have many participants betting much money.

FabHK2 days ago
You raise a good point: There's nothing intrinsically good about betting and trading venues, and the sane default option might well be to prohibit it. We allow stock and bond trading as it fulfils important functions [1].

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.

At least the stock market is supposed to have a purpose besides gambling, to raise investment for companies. (Whether it's actually successful at that is a separate matter.) And anyways, your scenario would probably be considered insider trading, and that's already banned.

This is very naive. Many people have incentives to manipulate the financial markets, also with real world consequences. Should we ban financial markets as a result?

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.

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.

pimterry2 days ago
> Let's not pretend that Spain of all places is caring about horribly destructive psuedo-gambling.

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?

jmorenoamor2 days ago
Ludopaths often try to put on the same level national lotteries with sports betting and other means of information based betting.

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'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.

XorNot1 day ago
Its just stochastic terrorism is the thing. Betting markets on a a negative outcome are ginning up a big "you could make money if the bad thing actually happens" and over enough scale you'll get that idea into the head of someone who concludes they should try and make it happen.

This is the same reason it is generally illegal to make public statements lamenting that someone hasn't killed a person.

https://en.wikipedia.org/wiki/Will_no_one_rid_me_of_this_tur...

bluGill1 day ago
The problem is if you are a criminal you need to cover your tracks and your client tracks. Someone can meet with an assassin to kill so and so on a street corner. However how do you get a large amount of cash to the assassin if they pull the murder off. Large amounts of cash are too often tracked, and most other electronic payments are as well. Bitcoin has a public ledger that is not as anonymous as advocates like to claim (and the police are presumably getting better at understanding it)

I don't know if a contract is a good way, but it gives some deniability.

jmyeet2 days ago
I would go further than this: all forms of online gambling should be banned, globally. It's probably sufficient to remove them from app stores and to remove their access to the international financial system, which is very doable.

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.

iamalizard1 day ago
I strongly disagree and think all forms of gambling should be legal.

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.

Pushing it to black markets takes away the possibility of heavy regulation (which absolutely should be in place), and stigmatises victims (gamblers), making it harder to come clean to friends and family. I agree with your assesment that no one should even start to gamble, I just doubt that declaring it illegal will achieve that.

AirBnb and Uber both had the same approach of basically saying "Oops we didn't know" until the law (and others) cracked down on them, I'm sure someone could find older examples too, and surely tons of examples outside of Spain too.

What? Maybe you visited a particularly casino-heavy area, but in general there aren't many casinos in Spain. In many regions (e.g. mine) they're restricted to one per province. My city (250K population in the core, metropolitan area about 500K) has one. Madrid (6M metropolitan area) has four, Barcelona (5M) has one.

Sports betting places on the other hand have multiplied like fungi in the last two decades, unfortunately.

All of these "politican out" markets will resolve to true if the politician dies: https://polymarket.com/predictions/out.

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.

the entire point of the argument is that they're the same people. Military bets appear to have significantly higher rates of insider trading than baseline[1], which implies two things, both catastrophic. One is that the markets leak classified information (which is the entire point of the market and it should be a national security no brainer to close it for that reason alone) but the even worse scenario is causality in the other direction, that a bet leads someone to take a military decision.

The utility is a fairly robust signal about the probability of certain events occurring. It's pretty helpful for grounding your beliefs about the world (in certain domains).

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_gipsyabout 23 hours ago
There is nothing undemocratic about this.

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.

jimnotgymabout 23 hours ago
Agree, the ministry just applied the existing law. Simple.
torceteabout 2 hours ago
Again, assuming separation of powers: In a democracy, ministries are part of the executive branch. Their role is to follow and implement the law, not to judge violations.

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.

It has been crazy seeing the explosion of Polymarket and Kalshi in comparison to Betfair.

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.

Equities are underlying collateral. Prediction markets are literally just betting on an outcome, no underlying asset exists.

Prediction Markets act the same way as Gambling Exchange - the assets are denominated as both sides of the book minus the spread.

What collateral is underlying the massive, state-sponsored, Spanish lottery ticket and scratch off racket?

I don't think you'd find anyone arguing that the lottery isn't gambling, so I'm not sure what argument you're trying to make here.

A casino is by definition a house that takes rake and is not the government or one of its subsidiaries ...

Collateral is not uncommon in gambling (e.g. pink slips). That does not seem to distinguish gambling from speculating.

That's not collateral, that's the thing being wagered.

Even if it was the same --I think it's not-- you'll need a "SIBE operator license", and cannot do it solo, you have to be an employee of an authorized firm (bank, broker or dealer).

It seems redundant to have two different regulatory systems for slightly different kinds of speculation.

I think it's fine. Here renting (or teaching) light sails (light catamaran) needs a different license than renting (or teaching) any sail cruiser, including catamarans, despite being basically the same object (boats with sails). Feels that the small differences are enough to justify a different regime.

There are all sorts of different regulatory systems for all sorts of slightly different kinds of things.

It's not like equities markets are unregulated, be serious.

Right they require a brokerage license instead because it's a different industry. Not sure what your comment is trying to say here.

Your comment explains long queues to lottery ticket offices every time I visit Spain:)

It's not cut and dry to differentiate between the act and the wager.

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.

It's a roulette that you can actually manipulate. that 's why it's worse.
