Polymarket Vows Insider Trading Crackdown as Traders Bet $12M on CLARITY Act

Polymarket is stepping up efforts to combat insider trading and other suspicious activity on its platform as political prediction markets attract significant investment. The company has allocated resources to enhance its surveillance systems, which will be particularly important as the US midterm elections approach. Currently, traders are wagering nearly $12 million on whether the CLARITY Act will become law in 2026, with only a 15% likelihood assigned to this outcome.

Polymarket's new investigations chief, a former FBI investigator, assured that the company has the necessary tools to detect abnormal trading patterns ahead of the midterms. The CLARITY Act's low probability reflects the challenges of predicting legislative outcomes, as insiders may possess confidential information that the broader market is unaware of.

Polymarket has referred over 100 cases to law enforcement, including one involving a US soldier who allegedly used a trading account connected to the capture of Venezuelan leader Nicolás Maduro. The company faced scrutiny for allowing Americans to access its platform in the past, settling the matter by obtaining the required registration and establishing a separate US-based exchange.

As Polymarket remains vigilant in maintaining the integrity of its markets, the organization continues to monitor politically sensitive prediction contracts and cooperate with regulatory authorities.
