~10 hours or so before the announcement bets on her skyrocketed on Polymarket

Someone without any history whatsoever put 70k on her 5 hours before the announcement

Trump was never above 5-10% and out of nowhere she was the winner (see the 1 day market view) https://polymarket.com/event/nobel-peace-prize-winner-2025?t...

This isn't illegal but feels like it should be illegal. You don't see corporate officers trade their stocks right before a big announcement, because there are laws on it.

Other than the fact that polymarket is legally not a stock market, what really is the difference between insider trading on a stock market vs insider trading on polymarket? Does anyone have a good argument for why one should be illegal while the other is legal?

The argument goes, the purpose of prediction markets is not to be fair, it's to provide information. Allowing insider trading benefits that purpose. And I think that's fair - this is not a place to invest your retirement savings, it's essentially gambling.

I kind of feel like abusing the information asymmetry when doing insider trading in a betting market should be illegal regardless if the purpose is to provide information or not, or if it's considered gambling or not. Just like doing so with stocks is illegal today.

why? The purpose of the prediction market is not to be fair to market participants, it's to aggregate information regarding an event. There is a public benefit to allowing participants to bet on insider information. It could be even argued there is nothing unfair about it if everyone is free to do it/can anticipate others might have insider info. If we actually limited the market to participants who have insider information(not feasible because we can't verify), that'd be a great public utility. this is the next best thing for all those who don't participate in it. These are specialized markets and we shouldn't rush to 'protect' people who bet on very technical events happening.
