WASHINGTON, D.C. — Six members of Congress introduced competing bills between January and March 2026 to tighten regulation of prediction markets through restrictions on public officials and certain types of wagers. The proposed legislation would ban federal officials from trading on prediction markets and prohibit bets on sensitive events including terrorism, assassination, and sports.

Rep. Ritchie Torres introduced the Public Integrity in Financial Prediction Markets Act in January. The legislation would ban federal elected officials, political appointees, executive branch staffers, and congressional staff from betting on outcomes when they have nonpublic information related to the transaction or might be able to obtain such information through their official duties.

Kalshi has expressed support for the Public Integrity in Financial Prediction Markets Act and emphasized that its rules already forbid insider trading. "I see my bill not as a ceiling, but as a floor for prediction market regulation," Torres said.

Sens. Jeff Merkley of Oregon and Amy Klobuchar of Minnesota introduced the End Prediction Market Corruption Act in March. The bill would ban the president, the vice president, and members of Congress from trading on prediction market platforms. The legislation would prevent senior executive branch officials from trading on outcomes in which they are involved or have influence through their official duties. "When public officials use non-public information to win a bet, you have the perfect recipe to undermine the public's belief that government officials are working for the public good, not for their own personal profits," Merkley said.

Sen. Chris Murphy of Connecticut and Rep. Greg Casar of Texas introduced the Banning Event Trading on Sensitive Operations and Federal Functions Act in March. The bill would ban prediction market trading on non-financial government actions, terrorism, assassination, war, and any event where individuals know or can control the outcome. The legislation would ban prediction market trading on events such as the Oscars and the Super Bowl halftime show. "When people get on their phone and see these prediction markets, they expect that there are rules to make sure the game isn't rigged against them. I think that voters would clearly stand with us, saying we want to make sure that you aren't betting on a rigged poker game," Casar said in an interview.

Sen. Richard Blumenthal of Connecticut introduced the Prediction Markets Security and Integrity Act in March. The legislation includes an explicit ban on insider trading and age verification to prevent people under 21 from using prediction market platforms. The bill restricts the use of artificial intelligence to target gamblers and would reverse the Trump administration's move to assert jurisdiction over prediction markets and would open the platforms to state laws.

Rep. Dina Titus of Nevada introduced the Fair Markets and Sports Integrity Act in February. The legislation would ban sports trades and casino-style games from prediction markets.

Rep. Blake Moore of Utah and Rep. Salud Carbajal of California introduced the Event Contract Enforcement Act in March. The bill would ban trading on terrorism, assassination, war, sports and athletic competitions, and any illegal activities in prediction markets.
