House Administration Committee Chairman Bryan Steil introduced a bill this week that would bar members of Congress, their spouses, and dependents from wagering on political or public policy outcomes. The Stop Lawmakers from Predicting Act comes as prediction markets gain traction in both financial and political circles — and as Washington takes a harder look at how elected officials could profit from inside knowledge.
What the bill would do
The legislation would make it illegal for lawmakers and their immediate family members to place bets on political events, such as election results or the passage of specific legislation. Violations carry civil penalties of up to $2,000. The proposal does not restrict retail users from trading prediction markets — only those with direct policy knowledge.
Steil framed the bill as an ethics measure. The idea: if a lawmaker knows a bill is dead before it's public, they shouldn't be able to bet on that outcome. The ban extends the existing conflict-of-interest debate beyond stock trading into the newer world of event contracts, where political decisions become tradeable assets.
Why prediction markets are in the crosshairs
Prediction markets have drawn political scrutiny as they become more visible. Platforms like Polymarket and Kalshi let users trade on everything from Federal Reserve rate moves to who will win the next presidential election. That visibility has caught the attention of regulators and lawmakers alike.
For crypto-linked prediction markets, the bill sends a clear signal: event contracts are on Washington's radar. Even if this particular proposal doesn't become law, it suggests formal rules and restrictions could be coming. The line between a market and a gambling contract is blurry, and Congress is starting to draw its own boundaries.
The bill is still a proposal. It would need to pass both the House and Senate, then be signed by the president to take effect. That's a long road, and no committee markup or vote has been scheduled yet.
Still, the introduction itself matters. It marks the first time a sitting lawmaker has explicitly tried to wall off political prediction markets from the people who make the policies being traded on. Whether the bill moves forward or stalls, the conversation around who gets to bet on politics — and who shouldn't — is just getting started.
