US House Launches Insider Trading Probe Into Kalshi and Polymarket — Here's What That Means for Prediction Markets

WHY IT MATTERS

Prediction markets are platforms where people can place bets on real-world outcomes — like who will win an election or whether interest rates will go up. Think of them like a stock market, but instead of buying shares in companies, you're buying shares in outcomes. The concern here is 'insider trading,' which means someone with secret, non-public information uses it to make profitable bets — the same thing that's illegal in the stock market. Congress is now investigating whether this has been happening on Kalshi and Polymarket. This matters because prediction markets have become one of the most popular use cases in crypto, and how regulators handle this could shape whether these platforms thrive or get shut down.
