Lawmakers are flooding Capitol Hill with legislation aimed at curbing insider trading risks and controversial event contracts in prediction markets. Five separate bills introduced in recent months highlight the explosive growth of high-stakes trading activity. Legal analysts stress that congressional action alone fails to resolve deeper structural vulnerabilities in market oversight.
Rep. Gabe Amo, Sen. Chris Murphy, Rep. Greg Casar, and Rep. Yassamin Ansari lead a bicameral effort through the BETS OFF Act. This measure prohibits contracts tied to war, terrorism, assassination, or government actions in which participants exert influence over outcomes. The bill also strengthens enforcement against offshore platforms by amending gambling laws and targeting payment processors.
Surge in Legislative Proposals Exposes Growing Concerns Over Market Integrity
Industry specialists monitor the rapid accumulation of additional proposals. Rep. Adrian Smith and Rep. Nikki Budzinski introduce the PREDICT Act, which bars members of Congress, the president, vice president, and senior executive officials from trading contracts linked to political events or policy decisions. Sponsors insist the legislation safeguards public trust by eliminating any appearance of self-dealing.
Sens. Todd Young, Elissa Slotkin, John Curtis, and Adam Schiff advance the Public Integrity in Financial Prediction Markets Act. Their bill explicitly outlaws the use of material non-public information in trading while imposing strict conflict-of-interest rules and penalties. Platforms must now navigate these layered restrictions while preserving liquidity and broad user participation.
Sens. John Curtis and Adam Schiff introduce the Prediction Markets Are Gambling Act, which directly prohibits sports-style wagers on CFTC-registered exchanges. The sponsors emphasize that such contracts blur lines with traditional casino gaming and undermine the original intent of commodity futures law.
Key Prediction Market Reform Bills Introduced in 2026
| Bill Name | Primary Sponsors | Core Provisions | Status as of March 2026 |
|---|---|---|---|
| BETS OFF Act | Rep. Gabe Amo, Sen. Chris Murphy, Rep. Greg Casar | Bans contracts on war, terrorism, government actions; strengthens anti-gambling enforcement on offshore platforms | Introduced March 18 |
| PREDICT Act | Rep. Adrian Smith, Rep. Nikki Budzinski | Prohibits elected officials and senior executives from trading political and policy event contracts | Introduced March 25 |
| Public Integrity in Financial Prediction Markets Act | Sens. Todd Young, Elissa Slotkin, John Curtis, Adam Schiff | Bans use of material non-public information; restricts conflicts of interest for government personnel | Introduced March 26 |
| Prediction Markets Are Gambling Act | Sens. John Curtis, Adam Schiff | Prohibits sports and casino-style event contracts on regulated exchanges | Introduced March 23 |
These proposals signal a rare bipartisan consensus forming around the need for tighter controls. Democrats and Republicans voice alarm over well-timed trades that appear to capitalize on confidential details. Platforms respond by updating internal policies to stay ahead of potential federal mandates.
Polymarket Strengthens Rules as Congressional Pressure Mounts
In response, Polymarket rolled out enhanced market integrity measures across its DeFi platform and CFTC-regulated U.S. exchange on March 23. The updates explicitly prohibit trading on stolen confidential information, illegal tips, and positions in which users have authority to influence event outcomes. Company executives describe these changes as proactive steps that reinforce user protection and market quality.
Enforcement includes real-time surveillance, wallet bans, monetary penalties, and referrals to law enforcement when suspicious activity surfaces. Analysts praise the clarity these rules bring while noting that self-regulation still leaves gaps that federal statutes must address.
Platforms like Polymarket process billions in weekly volume amid geopolitical and economic uncertainty. Traders flock to contracts amid policy shifts and global developments, creating both opportunities and heightened regulatory scrutiny.

CFTC Advances Rulemaking While Congress Debates Broader Reforms
The Commodity Futures Trading Commission published an advance notice of proposed rulemaking on March 16, soliciting public input on event contract core principles and prohibited categories. Chair Michael Selig signals the agency’s commitment to real-time monitoring and the prevention of manipulation. This regulatory activity unfolds alongside the legislative flurry, creating a dual-track push for clarity.
Earlier enforcement advisories highlight cases involving the misuse of non-public information. The guidance underscores the agency’s existing authority under the Commodity Exchange Act to pursue fraud and manipulative schemes. Industry insiders view it as a warning that self-policing must improve or face stronger federal intervention.
Legal Experts Caution Congress Cannot Resolve Every Enforcement Hurdle
Policy specialists argue that several fundamental problems defy simple legislative solutions. Offshore operations evade direct CFTC jurisdiction even when U.S. users participate. Congress possesses limited tools to compel foreign entities to adopt identical compliance standards or share audit trails in real time.
Coinbase’s top lawyer contends that prediction markets differ fundamentally from gambling and predicts the Supreme Court will ultimately affirm their status under existing commodity law. This perspective fuels optimism among platform advocates who view over-regulation as a threat to informational efficiency and innovation.
Rep. Alexandria Ocasio-Cortez joins former Trump chief of staff Mick Mulvaney in calling for stronger insider trading safeguards. Their unusual alignment highlights the breadth of concern that well-placed individuals could profit from sensitive government knowledge.
Recent high-volume trades tied to sensitive geopolitical developments intensify the debate. Platforms implement new surveillance protocols, yet experts question whether these voluntary measures suffice without statutory backing and dedicated enforcement resources.

Bipartisan Momentum Builds as Platforms Adapt to Evolving Landscape
Sen. Adam Schiff and Rep. Greg Casar emphasize the moral imperative to prevent profiting from tragedy or classified operations. Their bills target contracts that could incentivize bad actors or compromise national security. Supporters insist these restrictions preserve the core value of prediction markets while eliminating exploitable loopholes.
Critics within the industry counter that overly broad bans could stifle the very price-discovery mechanism that makes these platforms valuable. They point to historical data showing how aggregated trader wisdom often outperforms traditional polls or expert forecasts. The tension between innovation and integrity animates every hearing and press release.
Analysts track trading volumes that continue setting records even as regulatory clouds gather. Users bet on Federal Reserve decisions, cryptocurrency thresholds, and emerging technology trends with growing sophistication. This sustained activity underscores the platforms’ resilience and the public’s appetite for event-driven financial instruments.
Core Categories of Prohibited Insider Trading Under Recent Polymarket Rules
| Prohibited Conduct | Description | Enforcement Measures |
|---|---|---|
| Trading on Stolen Confidential Information | Using non-public details that breach a duty of trust or confidence | Participation by individuals with the authority to affect the event |
| Trading on Illegal Tips | Acting on information passed by someone who violated their own duty | Real-time surveillance and account suspension |
| Trading by Influencers of Outcomes | Participation by individuals with authority to affect the event | Preemptive contract restrictions and audits |
These enhancements demonstrate platforms’ willingness to evolve ahead of legislation. Still, legal analysts maintain that self-imposed rules cannot substitute for uniform federal standards enforceable across borders. The coming months will test whether Congress can bridge that gap or whether platforms will continue operating in a regulatory gray zone.
The stakes extend far beyond individual profits. Accurate market signals inform policy debates, corporate strategy, and public discourse. When integrity falters, confidence erodes, and the informational benefits diminish. Lawmakers wrestle with this balance while platforms innovate under pressure.
Ultimately, the flurry of 2026 bills signals a turning point. The prediction market regulation Congress pursues today will shape how these powerful tools serve society tomorrow. Legal experts caution patience and precision. They remind everyone that hasty fixes risk unintended consequences, while ignoring persistent enforcement realities could invite greater abuse.
Stakeholders on all sides watch closely as committees schedule hearings and the CFTC digests public comments. The outcome will determine whether these markets mature into trusted institutions or remain shadowed by doubt.
