#Polymarket预测市场 Polymarket's insider trading incident this time is truly incredible. A new account bet $32,500 on Maduro's resignation and made over $400,000 in less than 24 hours, with a return of over 1200%. The most outrageous part is that the price increase happened several hours before Trump's official announcement, which is clearly insider trading.

Now, U.S. lawmakers are directly proposing legislation to ban it, prohibiting government officials from trading related prediction market contracts when they possess significant non-public information. It has also been revealed that the trader's funding source may be linked to a wealthy individual, and on-chain data can easily reveal this.

To be honest, the logic of prediction markets itself isn't problematic, but once they become tools for those with an information advantage to harvest profits, it's over. After this incident was exposed, regulatory scrutiny of prediction markets is likely to become increasingly strict. Major platforms are also eager to distance themselves, claiming their rules have long prohibited such behavior. Anyway, let's wait and see how they handle the follow-up.
