A bipartisan group of U.S. lawmakers has introduced legislation that would prohibit the president, vice president, and all members of Congress from participating in prediction markets, citing concerns that federal officials could exploit insider knowledge of policy outcomes for financial gain.
The bill, known as the PREDICT Act, arrives as prediction market platforms have surged in popularity and trading volume, drawing scrutiny over whether elected officials with access to non-public information hold an unfair edge over retail participants.

What the PREDICT Act Would Prohibit
The legislation was introduced in the Senate by Senators John Curtis (R-UT) and Adam Schiff (D-CA), with companion legislation in the House led by Representatives Adrian Smith (R-NE) and Nikki Budzinski (D-IL). The bipartisan structure signals that concerns about officials trading on prediction markets cut across party lines.
The bill would bar the sitting president, vice president, and all 535 members of Congress from trading on prediction market platforms. That scope covers both regulated venues like Kalshi and crypto-native platforms like Polymarket, which operates on the Polygon blockchain.
Officials Subject to the Proposed Ban

Federal officials, including the President, Vice President, and all 535 members of Congress, who would be prohibited from participating in prediction markets under the proposed legislation.
Representative Seth Moulton (D-MA) has also been involved in parallel efforts targeting prediction market participation by lawmakers, reinforcing the growing bipartisan consensus that current ethics rules do not adequately address the unique risks these platforms create for officeholders.
The bill explicitly names prediction markets as the target rather than applying a broader financial trading restriction, distinguishing it from previous efforts like the STOCK Act, which focused on traditional securities. This specificity matters for crypto readers: the legislation treats prediction market contracts as a distinct asset class requiring its own prohibition for federal officials.
Why Lawmakers See a Conflict of Interest
The core rationale is straightforward. Members of Congress vote on legislation, receive classified briefings, and have advance knowledge of regulatory actions. Prediction markets allow participants to wager on the outcomes of political events, from election results to policy decisions.
When the people making those decisions can also bet on them, the conflict of interest is structural. A senator who knows a trade deal is about to collapse could profit by betting against market sentiment on that outcome. A president with advance knowledge of an executive order could position trades before public announcement.
This concern is not hypothetical. Congress has wrestled with similar issues around stock trading for over a decade. The STOCK Act, signed in 2012, was designed to prohibit insider trading by members of Congress and their staff based on non-public information gained through their official positions.
But the STOCK Act was written for traditional securities markets. Prediction markets, which allow bets on event outcomes rather than asset prices, fall outside its scope. The PREDICT Act is designed to close that gap, applying a similar ethical standard to a new category of financial instrument that has grown rapidly since 2024.
The timing also reflects growing public frustration with federal officials’ financial activities. Congressional stock trading disclosures have repeatedly generated controversy, and the rise of high-volume prediction markets on platforms like Polymarket has created a new avenue for potential abuse that existing law does not address.
What This Means for Crypto Prediction Market Platforms
For Polymarket, the dominant crypto-native prediction market, this bill adds a new layer to an already complicated U.S. regulatory picture. Polymarket settled with the Commodity Futures Trading Commission (CFTC) in 2022, paying a $1.4 million fine and agreeing to wind down its U.S.-facing operations. American users are currently barred from the platform under that settlement.
The PREDICT Act targets a different problem. Rather than restricting which users can access prediction markets (the CFTC’s approach), it restricts which individuals are prohibited from participating regardless of platform. If enacted, it would apply whether an official used Kalshi, a CFTC-regulated exchange, or found a way to access a decentralized protocol like Polymarket.
The enforcement question is where things get complicated for decentralized trading platforms. Regulated, centralized prediction markets like Kalshi can implement identity verification to screen out prohibited users. Decentralized protocols operating on-chain have no built-in mechanism to verify whether a wallet belongs to a member of Congress.
If the bill includes enforcement provisions requiring platforms to screen users, it could increase pressure on decentralized prediction market protocols to implement know-your-customer (KYC) measures. That would represent a significant shift for DeFi platforms that have historically resisted identity-based access controls.
However, the bill’s primary enforcement mechanism is more likely to target the officials themselves rather than the platforms. Similar to how the STOCK Act imposes penalties on the traders rather than the exchanges, the PREDICT Act would likely make it a violation for the official to participate, not for the platform to fail to block them.
The broader signal matters as much as the specific provision. Congressional attention to prediction markets, even when focused narrowly on official conduct, increases the regulatory surface area for the entire sector. Platforms building in the prediction market space, including those exploring tokenized financial instruments, should view this as an indicator that legislators are paying closer attention to how these markets function.
Legislative Path and What to Watch
The bill has been introduced in both chambers simultaneously, which gives it a procedural advantage over single-chamber proposals. Companion bills in the House and Senate can advance through committee in parallel, accelerating the timeline if there is sufficient political will.
Bipartisan sponsorship also improves the bill’s chances. With both Republican and Democratic sponsors in each chamber, the legislation is positioned as an ethics measure rather than a partisan initiative. That framing makes it harder for leadership in either party to ignore.
That said, many crypto-related and financial ethics bills have been introduced in recent congressional sessions without advancing to a vote. The STOCK Act itself took years of public pressure and media coverage of congressional trading scandals before it was finally passed. Prediction market regulation does not yet carry the same level of public salience.
Key milestones to watch include committee assignment and whether hearings are scheduled. If the bill is referred to the Senate Banking Committee or the House Financial Services Committee, it will compete with a crowded agenda of broader crypto regulatory proposals already under consideration in the 2025-2026 session.
The political dynamics around prediction markets are also evolving rapidly. Multiple congressional proposals targeting prediction markets have surfaced in recent months, suggesting that even if this specific bill stalls, the issue is unlikely to disappear from the legislative agenda.
FAQ
Does this bill affect regular retail users of prediction markets?
No. The proposed ban is narrowly targeted at the president, vice president, and members of Congress. Retail users who participate in prediction markets on platforms like Kalshi or Polymarket (where legally available) would not be affected by this legislation.
Are prediction markets already regulated in the United States?
Yes. The CFTC has jurisdiction over prediction markets as event contracts. Kalshi operates as a CFTC-regulated designated contract market. Polymarket settled with the CFTC in 2022 and is currently unavailable to U.S. users. The PREDICT Act would add a new restriction on top of this existing framework, specifically targeting federal officials.
Could this bill force decentralized prediction market protocols to implement identity verification?
It is unlikely that the bill’s primary enforcement mechanism would target platforms directly. The more probable approach is to impose penalties on the officials themselves for participating, similar to how the STOCK Act works. However, if regulators interpret the bill broadly, it could create indirect pressure on decentralized protocols to adopt KYC measures, though enforcement against truly decentralized, non-custodial protocols remains a legally unresolved challenge.
