CFTC Releases 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 process for evaluating event contracts traded on platforms such as Kalshi and Polymarket, and this step comes as trading volumes in these venues continue to expand rapidly. The notice outlines categories of contracts that would face prohibition or heightened review, while leaving room for many others that align with existing public interest standards.
Scope of the Proposed Framework
Event contracts allow participants to take positions on the occurrence or non-occurrence of specific future events, and the CFTC proposal establishes criteria for determining whether such contracts should be permitted on CFTC-regulated exchanges. Under the new approach the agency would examine contracts that reference war, assassination, terrorism, or certain illegal activities, along with particular sports prop bets involving player injuries, officiating decisions, or outcomes like baseball first-pitch results. Most other sports-related markets would remain available provided they do not trigger the listed concerns.
Categories Facing Prohibition or Scrutiny
Contracts tied directly to acts of war or terrorism would receive automatic prohibition because they involve events that regulators view as incompatible with market integrity, and similar treatment would apply to assassination references or markets on specified illegal activities. High-risk sports props such as injury outcomes or officiating calls fall into a review category where platforms must demonstrate that the contracts serve a legitimate hedging or price-discovery purpose rather than functioning primarily as entertainment vehicles. The proposal lists these areas explicitly so that exchanges receive clear guidance before listing new products.
Permitted Markets and Public Interest Test
Platforms could continue to offer the majority of sports event contracts and other event-based products that do not fall into the prohibited or scrutinized buckets, and the CFTC would apply a public interest determination to any contract that raises questions. This determination considers factors including whether the contract could be used for hedging commercial risks, whether it might create incentives for harmful behavior, and whether trading would undermine broader regulatory objectives. Data from recent years shows increasing participation in these markets, which prompted the agency to develop standardized review procedures rather than handling each contract through ad-hoc no-action letters.
The notice of proposed rulemaking appears in the Federal Register and invites public comment for a period that typically spans sixty days, after which the CFTC would consider revisions before issuing a final rule. Prediction Markets; Public Interest Determinations (Notice of Proposed Rulemaking) provides the full text and explains how the framework aligns with the Commodity Exchange Act provisions that authorize the agency to review novel contract types.
Objectives Behind the Rulemaking
Agency officials state that the proposal seeks to deliver regulatory clarity for market participants while protecting the integrity of CFTC-regulated venues, and the same document notes support for responsible innovation in a sector that has attracted significant capital inflows. By defining upfront which contracts will face barriers, the CFTC aims to reduce uncertainty that previously led some platforms to delay product launches or seek informal guidance. The rulemaking also addresses concerns that certain event contracts could conflict with federal or state laws, thereby exposing exchanges and traders to enforcement actions outside the CFTC's direct oversight.
Impact on Kalshi and Polymarket Operations
Kalshi and Polymarket would need to adjust their contract submission processes to include additional documentation when a proposed market touches any of the flagged categories, and existing contracts in those areas might require delisting or modification once a final rule takes effect. Most routine sports markets and election-related or economic indicator contracts would proceed under the current streamlined review, provided they avoid the enumerated high-risk features. Observers note that the distinction between permitted and restricted contracts creates a clearer operational roadmap for compliance teams at both exchanges.
Timeline and Next Steps
The proposal carries a publication date of June 10, 2026, with comments due later in the summer, and agency staff have indicated that final rules could be adopted before the end of the calendar year if the comment record supports swift action. During the interim period platforms may continue to list contracts under existing no-action relief, yet they receive advance notice of the standards that will govern future decisions. This sequencing allows market participants time to prepare systems and policies without an immediate disruption to trading activity.
Conclusion
The CFTC's June 2026 proposal introduces a defined review process for event contracts on prediction market platforms, specifies categories subject to prohibition or extra scrutiny, and preserves access to the broader range of markets that meet public interest criteria. Implementation of the final rule will determine how Kalshi, Polymarket, and similar venues structure their offerings going forward, while the comment period offers stakeholders an opportunity to provide input on the precise boundaries of the framework.
