Rep. Bryan Steil bill would bar Congress families from policy bets on Kalshi and Polymarket
The Stop Lawmakers from Predicting Act sets a $2,000-or-10% civil penalty and excludes White House officials.
Wisconsin Rep. Bryan Steil introduced the Stop Lawmakers from Predicting Act to restrict members of Congress and immediate family from trading policy- and politics-linked event contracts on prediction markets. The proposal sets a civil penalty for violations, starts a 180-day clock after enactment, and does not apply to White House officials.
Key Takeaways
- A new House proposal would restrict members of Congress, spouses, and dependent children from trading policy-aligned event contracts on prediction markets.
- The bill targets wagers tied to government actions and “political outcomes,” while leaving general platform use and sports betting outside its stated scope.
- Violations would trigger a civil penalty set at $2,000 or 10% of the prohibited bet value.
- The restriction would not cover White House officials, and would take effect 180 days after enactment if it becomes law.
Steil’s bill targets Congress family accounts on Kalshi and Polymarket
Wisconsin Representative Bryan Steil, chair of the House subcommittee on digital assets, introduced legislation aimed at limiting how lawmakers and their households interact with prediction markets.
The proposal, titled the Stop Lawmakers from Predicting Act, would bar “members of Congress, their spouses, and dependent children” from using policy-aligned event contracts on platforms including Kalshi and Polymarket.
For traders, the immediate signal is what the bill does not do. It is constructed as a conflict-of-interest restriction on Congress-linked accounts, not a broad attempt to shut down prediction markets as a product category. That keeps the wider market structure intact while putting compliance pressure on a specific, politically sensitive user segment.
What the ban covers: policy actions, government decisions, and political outcomes
The bill’s prohibited activity is framed as “wagering on public policy issues and political outcomes,” with the scope described as wagers on specific government policies, government actions, and “political outcomes,” a category that would presumably include election results.
At the same time, the proposal does not specifically bar lawmakers from using prediction market platforms generally, and it does not prohibit sports bets. That distinction matters because it narrows the restriction to contracts most exposed to insider-information narratives rather than treating all event contracts as the same risk.
The most notable carve-out is institutional, not product-based. The restriction does not extend to White House officials, explicitly including President Donald Trump and Vice President JD Vance. That creates an uneven compliance perimeter that could become a negotiation point if the bill moves forward, or a reason it stalls if lawmakers push to broaden coverage.
Penalty math and the 180-day clock if the bill becomes law
The enforcement design is civil and formula-based. Elected officials found in violation would face a penalty of $2,000 or 10% of the value of the prohibited bets.
If Congress passes the bill and the president signs it, the restrictions would take effect 180 days after enactment. Practically, that back-loads any real compliance impact even under a fast legislative timeline, giving platforms time to adjust KYC and account-screening policies if they choose to proactively align.
The bill lands amid heightened sensitivity around insider-profit concerns tied to event contracts. Public attention was linked to an incident in which a soldier allegedly made more than $400,000 betting on the removal of Venezuela President Nicolás Maduro after he was ousted by US forces in January 2026.
Signals to Watch for US bill targets prediction markets policy
The first tell will be whether the Stop Lawmakers from Predicting Act attracts co-sponsors or gets scheduled for subcommittee or committee consideration in the House. Without that, it is headline risk more than executable policy.
Next is amendment risk. Any move to expand coverage beyond Congress to include White House officials, or to redefine what qualifies as “policy-aligned event contracts,” would change the compliance surface area for platforms and the access risk traders price in.
Regulatory backdrop remains live. Under President Trump, the Commodity Futures Trading Commission and chair Michael Selig have asserted “exclusive jurisdiction” over prediction markets, and the agency has filed multiple lawsuits against state-level authorities restricting or banning the platforms. The CFTC’s argument is that event contracts can be regulated as “swaps” under the Commodity Exchange Act rather than treated as bets. Some experts have suggested the fight could reach the Supreme Court, though no timeline was provided.
If the bill advances all the way to enactment, the start of the 180-day countdown becomes the practical deadline that matters for platform policy changes and user eligibility checks.
Why this matters for prediction-market access and compliance narratives
I read this as a targeted conflict-of-interest patch, not a product ban. The bill is narrow by design, and that usually means the political goal is to neutralize an optics problem without detonating a market that is already being pulled into federal jurisdiction debates.
The threshold that matters is whether the carve-out for White House officials survives. If it holds, the setup starts to look structural rather than narrative-driven, because it hard-codes an uneven compliance perimeter that platforms and traders will have to route around, and that is when “access risk” becomes a real input instead of a talking point.
