GOP bill targets Congress betting: prediction markets face regulatory squeeze
A new Republican bill, the “Stop Lawmakers From Predicting Act,” would stop members of Congress from betting on political outcomes through platforms such as Kalshi and Polymarket. Fair enough. My take: if anyone should stay out of markets tied to elections, agency decisions, or policy fights, it is the people closest to that information.
Representative Bryan Steil of Wisconsin, chair of the Committee on House Administration, described the bill as an ethics rule. “It is inappropriate for members of Congress to trade on the outcomes of elections or public policy,” he said. The bill applies to real-money wagers tied to government policy, official actions, elections, or other political outcomes. House members, their spouses, and dependent children could not place those bets. The ban is narrow. It covers political and policy markets, including anything a lawmaker learned through congressional work. It would still allow bets on unrelated events such as sports.
The penalties have teeth. A violator would pay at least $2,000 or 10% of the trade’s value, whichever is higher, and would lose any net profit from the bet. Lawmakers also could not use office funds or campaign money to pay the fine. That closes the loophole everyone would have spotted in about five seconds. The proposal has backing from House Speaker Mike Johnson and President Donald Trump. The Senate took a similar step earlier this year when it adopted a rule barring senators and staff from betting on prediction markets.
The bill comes as prediction markets are already getting serious attention in Washington. The House Oversight Committee has opened an inquiry into Polymarket and Kalshi, with insider trading protections at the center of the review. Why does this matter? Because this is no longer just a weird corner of election betting.
Representative James Comer, who chairs the committee, called the space a “wild west” with “no rules.” It is a blunt line, but it fits the mood. Still, the usual take is too simple: “prediction markets are gambling, so regulate them like gambling.” That is only half right. The CFTC’s pressure on prediction markets could reach beyond election betting. It probably will not move spot crypto markets by itself. But it could affect how regulators treat DeFi products that resemble speculative contracts. If the CFTC gains more authority over these markets, similar DeFi products, including synthetic assets and perpetual futures, may get closer scrutiny. We have seen this before. When the SEC pressured staking services, some platforms changed their products instead of waiting for a larger fight.
Kalshi is also fighting at the state level. The company has sued Minnesota to block what it calls the first US felony ban on prediction markets, arguing that its contracts are federally regulated derivatives under the CFTC’s exclusive authority. The money involved is not small anymore. Polymarket and Kalshi together cleared $25.7 billion in volume in April. I’ll be honest: that is a strange sentence to write about what used to feel like a niche crypto betting corner, but here we are. The scale makes Kalshi and Polymarket hard for regulators to ignore. For crypto traders, this is not just a Kalshi or Polymarket story. Regulatory pressure on one crypto-linked financial product can spread into the rest of the market. When investors start pricing in future restrictions, volatility usually follows. Bitcoin ETF delays showed the same pattern: regulatory uncertainty helped keep BTC near the $27,000 to $30,000 range for months before approval finally came through.
The worry behind Steil’s bill is simple. Members of Congress often know things the public does not know yet: whether a bill has the votes, when an agency may act, or when a policy fight is about to turn. That is the problem.
A liquid market that pays out on those outcomes creates an obvious temptation. It begins to look like the political version of insider trading in stocks, which lawmakers already face separate restrictions on. Counter to the usual advice, a narrow ban may not be easier to enforce than a broad one. By allowing sports and other unrelated bets, the bill tries to target the trades most open to abuse without banning prediction markets altogether. That line may be harder to police than it sounds, especially once spouses and adult family members enter the picture. The “Stop Lawmakers From Predicting Act” still has to get through committee and a floor vote, even with support from the speaker and the president.
What this means
Regulators are paying attention to prediction markets because the platforms got too big to stay odd and ignored. The crypto connection makes the fight even more charged. Is this overkill? For a market clearing $25.7 billion in April, no.
The $25.7 billion April volume matters because it shows how quickly these markets can move from novelty to real financial infrastructure. For crypto investors, the question is not only what happens to Kalshi or Polymarket. It is whether agencies use this fight to test arguments they may later apply to DeFi apps with similar payoff structures. Yes, this sounds broader than a congressional ethics bill. That is the point. If the CFTC comes out stronger here, DeFi protocols built around synthetic exposure, event contracts, or derivatives-style markets could face higher compliance costs. Some places could impose tighter limits or bans. Tokens tied to those ecosystems would probably take the first hit.
Watch the bill’s path through Congress, but do not expect it to move quickly. The more immediate story is the House Oversight probe into Polymarket and Kalshi. Findings from that investigation could push enforcement forward or give lawmakers wording for a broader bill. Kalshi’s Minnesota lawsuit also matters. A win could slow state bans and give federally regulated platforms more room to operate. A loss could invite other states to copy Minnesota’s approach. My read: traders should treat prediction market and DeFi derivatives tokens as headline-sensitive until this shakes out. CFTC statements are the ones I would watch most closely.
