Kalshi CEO: Insider trading easier to spot in prediction markets than stocks

Mansour elaborated that while a piece of information about a product release might lead someone to buy stock in the broad market, in prediction markets, the same information would be used to bet on specific event contracts, making the connection more direct and less ambiguous. He acknowledged that "fraudsters exist in any system" but emphasized Kalshi's rapid efforts to catch them.

The CEO's comments come as former New York Representative George Santos faces investigation by the Justice Department and the Commodity Futures Trading Commission for alleged insider trading on Kalshi. The platform flagged unusual trades linked to Santos's attendance at the State of the Union address.

To combat fears of insider trading, Kalshi has implemented measures including requiring traders to verify their employment and providing easy channels for whistleblowers to report suspicious activity. Despite these efforts, lawmakers have expressed skepticism, with several proposing bills to ban or restrict prediction markets. Minnesota Governor Tim Walz recently signed a statewide ban on such markets.
