US House Oversight Committee launches insider trading investigation into prediction markets!

The US House Oversight Committee has opened a formal investigation into insider trading on prediction markets, marking the first major congressional probe into an industry that has grown rapidly in political and financial relevance over the past two years.

Prediction markets — platforms where users bet on the outcomes of elections, policy decisions, and macro events — have attracted scrutiny for their potential to be exploited by participants with advance knowledge of non-public information. The concern is structural: unlike regulated securities exchanges, most prediction markets operate under lighter oversight frameworks, creating potential gaps that bad actors could exploit.

The investigation signals that Congress is no longer treating prediction markets as a niche curiosity.
