What Happened
Representative Bryan Steil, chair of the House Subcommittee on Digital Assets, introduced the Stop Lawmakers from Predicting Act on Thursday. The bill aims to block members of Congress, their spouses, and dependent children from betting on political outcomes via prediction markets like Polymarket and Kalshi.
The proposed legislation specifically targets event contracts tied to government policies, actions, and election results. It does not extend the prohibition to White House officials, a notable carve-out given President Trump’s son Donald Trump Jr.’s advisory roles with both platforms.
If enacted, the law would take effect 180 days after signing, closing a loophole that critics say allows lawmakers to profit from insider knowledge of legislative and regulatory moves.
The Numbers
The bill prescribes a penalty of $2,000 or 10% of the bet value—whichever is higher—for violations. By explicitly excluding executive branch officials, the legislation sidesteps potential conflicts with the Trump family, who have direct financial ties to prediction markets.
Prediction market volume has surged in recent years, with platforms like Polymarket facilitating billions in wagers on political events. The bill comes amid a broader CFTC push to assert exclusive jurisdiction over these contracts, with several lawsuits challenging state-level bans.
Why It Happened
Steil’s bill responds to growing unease over lawmakers potentially using non-public information to gain an edge on prediction markets. A recent incident involving a soldier who allegedly earned over $400,000 betting on the removal of Venezuela’s president underscored the risks of insider trading on these platforms.
The legislation also reflects the uneasy regulatory landscape. Federal and state regulators are locked in a tug-of-war over whether event contracts constitute illegal gambling or legitimate commodities trading under the Commodity Exchange Act, a fight that could soon land at the Supreme Court.
Broader Impact
The bill’s narrow focus on Congress—and its exclusion of the White House—raises conflict-of-interest concerns. With Trump Jr. actively promoting Kalshi and Polymarket, the carve-out may fuel public perception of regulatory capture.
For the prediction market industry, the measure signals that Washington is taking notice of their rapid growth. Even if Steil’s bill stalls, it adds momentum to the push for clearer federal guardrails, which could reshape the market’s legal foundation.
What to Watch Next
- Legislative Progress: Track whether the bill gains co-sponsors or passes through committee in the coming weeks.
- CFTC Lawsuits: Monitor ongoing legal battles as the commission seeks to override state restrictions on prediction markets.
- Supreme Court Potential: A circuit split on prediction market regulation could tee up a high-stakes Supreme Court case.
