[Robin Hanson: Opposes Comprehensive Ban on Insider Trading by Kalshi and Polymarket] According to Fortune magazine, as Kalshi and Polymarket cooperate with the CFTC to crack down on insider trading, George Mason University economics professor Robin Hanson expressed opposition, stating that insider participation in trading is the core value of prediction markets. He believes insider trading can improve price accuracy and enhance the market's information discovery function, and a comprehensive ban would weaken the role of prediction markets. Previously, the U.S. Department of Justice prosecuted a U.S. soldier for using classified intelligence to illegally profit approximately $400,000 by betting on Venezuela raid operations on Polymarket. Robin Hanson suggested that if government employees are prohibited from participating in prediction market trading, they should also be barred from speaking with journalists.
