CFTC Advances Proposed Rulemaking on Event Contracts for Prediction Markets

The U.S. Commodity Futures Trading Commission under the Trump administration issued a proposed rulemaking on June 10, 2026 that sets out a structured framework for reviewing event contracts traded on prediction market platforms including Kalshi and Polymarket, and the measure targets specific categories while allowing others to proceed when they align with public interest standards.

Details of the June 2026 Proposal

Under the new framework the CFTC would evaluate event contracts through a public interest lens that prohibits or subjects to heightened scrutiny markets tied to war, assassination, terrorism, and certain illegal activities along with high-risk sports propositions such as player injury outcomes, officiating decisions, or niche baseball markets like first-pitch results, yet the rules leave room for most conventional sports-related contracts and other event contracts that regulators determine do not run counter to broader societal protections.

Observers note that this approach builds on existing CFTC authority under the Commodity Exchange Act while responding to the rapid expansion of prediction market activity in recent years, and the proposal document outlines criteria that platforms must meet when listing new contracts to maintain market integrity and prevent misuse of these instruments for purposes outside their intended scope.

Scope of Prohibited and Permitted Markets

The rulemaking identifies clear boundaries around contracts involving national security events or criminal conduct because those areas carry elevated risks of manipulation or conflict with federal statutes, and it extends similar review processes to sports prop bets that could influence game fairness or participant welfare such as injury timing or referee calls, whereas standard game outcomes, seasonal standings, and player performance statistics without direct ties to prohibited elements remain eligible for approval when they satisfy the public interest test.

Researchers tracking prediction market trends point out that platforms like Kalshi and Polymarket have already listed thousands of contracts across politics, economics, and entertainment, yet the new guidelines focus scrutiny on a narrow subset that could expose participants to undue harm or legal exposure, and this targeted method aims to preserve innovation in areas where contracts have demonstrated utility for price discovery and risk management.

Regulatory Objectives and Market Context

The proposal states three primary goals that include delivering clearer regulatory expectations for operators, safeguarding the integrity of event contract trading venues, and enabling responsible growth in a sector that has seen increased participation amid advances in digital trading technology, and CFTC staff developed the framework after reviewing public comments and market data collected over preceding months.

Those familiar with prior CFTC actions on event contracts recall earlier guidance from 2021 and 2023 that addressed similar concerns around election-related and politically sensitive markets, but the June 2026 version expands the review process to encompass a wider range of sports and current-event contracts while incorporating lessons from enforcement cases involving unregistered platforms, and the measure aligns with broader administration priorities on financial market oversight during the Trump term.

According to the Prediction Markets; Public Interest Determinations (Notice of Proposed Rulemaking) published shortly after the announcement, the CFTC will accept public comments for a 60-day period following the June 12, 2026 Federal Register posting, after which staff will consider revisions before any final rule takes effect, and this timeline allows market participants and academic analysts to submit data on how the proposed restrictions might affect liquidity in permitted categories.

Implications for Platforms and Participants

Kalshi and Polymarket would need to adjust their contract submission procedures to include detailed analyses demonstrating that new offerings avoid the prohibited categories, and compliance teams at these firms have already begun mapping existing listings against the draft criteria to identify any that require modification or removal, while most sports markets centered on team victories or championship results would continue without interruption under the outlined standards.

Market data compiled by independent analytics groups shows prediction market volumes reached record levels in the first half of 2026, driven largely by interest in U.S. political events and major sports leagues, yet the CFTC proposal signals that future growth in this space will occur within defined guardrails designed to reduce systemic and reputational risks, and platform operators have indicated they plan to maintain open dialogue with regulators throughout the comment period.

Conclusion

The June 10, 2026 proposed rulemaking represents a significant step toward formalizing oversight of event contracts on U.S.-accessible prediction markets, and it balances the need for regulatory clarity with support for contracts that deliver informational value without crossing into restricted territory, while the coming comment period will shape the final contours of these rules before implementation.
