U.S. House Committee Approves Bill Banning Lawmakers from Prediction Markets
0xBroomberg
The U.S. House Administration Committee voted 5–4 to approve a bill banning members of Congress from betting on political prediction markets, marking the first time this regulatory gap has entered a formal legislative track — but a party-line split on how far the ban should reach will shape its chances on the House floor.
What does this bill actually ban?
It bars members of Congress and their spouses and dependent children from placing bets on prediction markets tied to government decisions or political actions.
The bill was pushed by committee chair Bryan Steil, a Wisconsin Republican, and cleared committee on a 5–4 vote.
This means → the bill has passed its committee hurdle and is now headed to a full House floor vote.
Why did Democrats vote against it?
All four "no" votes came from Democrats — the result split almost perfectly along party lines.
Top committee Democrat Joe Morelle (New York) called the bill too weak: it does not require lawmakers to sell existing stock holdings, nor does it ban them from trading on non-political prediction markets.
Morelle proposed an amendment to extend the ban to congressional staff, political candidates, and their families, and to explicitly name platforms like Polymarket and Kalshi — but the amendment was voted down 4–5.
What is the core divide between the two parties?
The Republican-led version targets only politically related prediction markets; Democrats want to cover all prediction-market platforms and a broader set of associated individuals.
In plain terms = Republicans want to regulate "bets linked to policy"; Democrats want to regulate "all prediction-market bets, period."
This divide will directly determine whether the bill can secure enough votes on the House floor.
How does this relate to the stock-trading ban?
Steil plans to bundle the prediction-market ban with a congressional stock-trading ban and bring both to a full House vote this summer.
The push to ban lawmakers from trading stocks has been going on for years; momentum has picked up this session with bipartisan leadership support and Trump's public endorsement.
This means → the prediction-market ban is not a standalone issue — it is riding a larger legislative vehicle aimed at lawmaker conflict-of-interest reform.
How far is this from becoming law?
The U.S. Senate has already unanimously adopted an internal rule banning senators and their staff from prediction-market trading — but that is a chamber rule, not a law.
Even if the House version passes a floor vote, the Senate must approve it in statutory form before it becomes binding law.
In plain terms = the Senate has already "policed its own members," but turning that into a law that binds everyone requires both chambers to complete the full legislative process.
