I mentioned this on a different post - the biggest problem with prediction markets is not the gambling or dumb people losing money. Its the fact that it gives very powerful people a vehicle to make lobsided bets on outcomes they control.
A small example of this would be NFL / NBA Refs fixing playoff games with a bad call or two. This actually happened 20 years ago, an NBA ref went to prison over being bribed just $2000 per game.
The much worse example is the fact that you can make 100-1 odds on whether the US airstrikes Iran today... or How many times Pam Bondi says the word "China" in a press conference.
This gets into a philosophical point about what a prediction market actually is. If it's a device for anonymously aggregating fragmented group information into a coherent accurate prediction, the lopsided bets are a feature; the only point of the market is the price signal, and the lopsided bets true up the price.
But most of us understand that prediction markets aren't that, no matter what Robin Hansen said when he was helping invent the modern incarnation of things like Polymarket and Kalshi. They're gambling venues, and we have "Nevada Gaming Commission"-style concerns about fairness. To me, the next logical step is to say that they should be heavily regulated, but in the era of DraftKings, that seems off the table.

A classic example is the color of the Queen's hat at Royal Ascot.

> Power's odds on brown went from 12-1, to 2-1, to even and finally to 8-11 before he yanked the bet at 11:30 a.m., 2½ hours before the Queen was due to show.
> "Someone must have been in the know. We laid 50 pounds at 20-1 and 200 pounds at 10-1 and some smaller bets," David Hood, spokesman for rival betting chain William Hill (search), told the Daily Telegraph.

That's the actual point. Everyone else is there to make money gambling, but the whole premise is to incentivize people with secret information to share it anonymously with the public, and take a reward for doing it.
All without traceability or secret drops or whatever.

I'm sceptical that prediction markets uniquely enable this. Like, if you want to bet on U.S. airstrikes in the short term, you could always buy oil options (or short exposed companies). If you're in for the long term, you're buying something that benefits from cheaper gas, e.g. an additives company.
A lot of these issues mostly disappear if you use play money.
It turns out that play money prediction markets are just as good as the real money ones.
+1
if you're not the person-in-complete-power, your bet is really likely to be 'rigged' against you
I'd rather play dice or buy lotteries
Plenty of more fun dynamics. For example, in some cases it becomes a way for voting for decisions one otherwise wouldn't control. If a person in position to make a decision doesn't really care about any choice in particular, seeing the prediction market lean one way would incentivize them to choose the opposite, making a short sale immediately before.
It also makes sense for the people voting: by betting against the outcome they want, they end up either a) paying for getting things their way, or b) getting consolation payoff if the decision makers pick the undesired choice.

This is quickly becoming the point of them, at least insofar as they are enjoying an extremely favorable regulatory environment courtesy of the Trump crew.
well, at least for really odd ones - like the china example - the liquidity is (probably) going to be really low. you need people buying both sides to make money.
But for big events/talked about stuff/etc ofc this is not true.
> Its the fact that it gives very powerful people a vehicle to make lobsided bets on outcomes they control.
OK, and? The market is just paying them to make information about their decisions public.
I think the war ones are the only real concern.
In the context of legislating prediction markets or not, sports is not a concern at all.
Whether it's a net positive or negative for important shit like war and corruption, we'll see, but if it helps in the important stuff, but damages sports, sorry bud.
It's a national security issue too.
Somebody poor grunt who chose to earn a living by laboring (which has proven to be much less effective than being born with money) will be putting fuel in the bombers and thinking "I could just make an anonymous bet..."
It's a national security issue.
We saw this with the Venezuela attack. A flurry of trading and someone made $400,000 for placing a bet mere hours before the "surprise" attack. https://www.pbs.org/newshour/nation/a-400000-payout-after-ma...
