Another problem is, people may actually want to bet on random outcomes, because of money laundering or simply because this is how gambling essentially works. That huge account could be an insider or a billionaire with a few hundreds k to burn. Or maybe they want to orient people’s opinions towards a certain outcome.

Claiming that price movement in a prediction market reveals some amount of truth implicitly assumes that:

- people bet on something they believe to be true, and not to sway other people’s opinions or simply to burn money,

- people bet on something they believe to be true because they have specific private information (e.g. I bet on the Red Sox not because I think they’re good but because I know things other don’t about their opponents, their physical conditions and so on).

- their belief is actually correct (eg if I’m in the CIA and I know that the Soviets are about to launch a nuclear missile I can bet on it… but I don’t know that an officer down the line will refuse to do that).

Even if this was true, there is an issue of timing and consequences. Example: imagine it’s 2011 and some CIA or DoD officer makes huge, sudden bets on the fact that Bin Laden will be caught. Some AQ people get wind of this and move Bin Laden somewhere else. Congrats, your price movement signaled non public information to the market!

Another issue is that these bets tend to rely on public sources, news reports and so on. A journalist in Israel was threatened to change his news reports so that certain people didn’t have to lose on a prediction market. This could become more and more common, and with the advent of AI generated pictures who are you going to believe? Are you losing money because you bet on the wrong outcome or simply because someone with enough resources ensured that your outcome was never going to be reported?

> Congrats, your price movement signaled non public information to the market!

so from bin laden's perspective, this would've been a good outcome isnt it?

Can't say what a good outcome is without saying who.

What if enemies of the USA had corrupt generals who also make bets on anti-US actions to profit personally, and inadvertently reveal information to the CIA/NSA, who then prevent such anti-US actions? Would that not have been a good outcome as well?

Information is information - and one cannot say if it's good or not. However, i am a believer that more information generally do good than bad - assuming the consumer of said information is smart.

> Are you losing money because you bet on the wrong outcome ...

It doesnt matter, because you chose to bet. You do not need to bet in order to make use of the information being revealed by those who are betting.

However, i am a believer that more information generally do good than bad - assuming the consumer of said information is smart Smart doesn’t always equal good. The consumer can be smart and use the information to benefit themselves (and possibly harming others), but this doesn’t necessarily justify releasing information. In fact, even Snowden, who famously released a lot of information, didn’t release everything. He applied his judgment and avoided publishing some stuff. Was his judgment correct? I don’t know. The question is - at some point, is information release always neutral? > Are you losing money because you bet on the wrong outcome ... It doesnt matter, because you chose to bet. You do not need to bet in order to make use of the information being revealed by those who are betting. What I’m saying is, if I bet on event X and X happens, I would expect to be paid. Instead I may not get paid simply because someone else who bet against X has the power to suppress any proof of X happening (via threats, money,…). This doesn’t happen with regular sport bets because sport events inherently have a lot of witnesses (physically present at the place where things are happening), there are referees, the teams themselves advertise the results, there is a professional league keeping scores and so on. If you bet on someone getting killed abroad by some military abroad, or military skirmish happening in a remote place, or other plausible but hard to verify event, faking something with AI or a friendly reporter is easier. And because people use cryptocurrencies in this platform, how can you prove active manipulation vs bona fide in some video some reporter published? “Hey, I just saw this video, who knew it was wrong?”. The argument that you can lose money simply because it’s a bet, even when you should have won, is not convincing. Ok, I can lose but if I win shouldn’t I get the money?
