Event contracts at a regulatory crossroads

An event contract pays a fixed amount if a defined outcome occurs. In the United States these contracts trade on designated contract markets registered with the Commodity Futures Trading Commission, which list them under rules that prohibit certain categories and give the agency authority to review others. On-chain prediction markets trade the same kinds of contract outside that framework. Both have grown quickly, and both sit in a regulatory position that is being contested in three places at once.

Rulemaking

The CFTC’s posture toward event contracts changed with a change in leadership in early 2025, from restrictive to permissive. Sidley Austin reported in February 2026 that the agency had signaled imminent rulemaking, and on 10 June 2026 the CFTC issued a proposed rule, published in the Federal Register as Prediction Markets; Public Interest Determinations, that would amend Rule 40.11 and establish a procedural framework for the agency’s authority to review contracts against the public interest. The Congressional Research Service has summarized the proposal and the policy questions it raises for Congress.

Enforcement

A permissive rulebook is not an absent one. In April 2026 the CFTC brought its first insider trading action concerning event contracts, and Kalshi announced disciplinary actions against participants who had traded on their own campaigns. The agency’s enforcement division has issued an advisory on prediction markets. For an institutional participant the message is that surveillance and conduct rules apply to event contracts as they do to any other derivative, and that trading on non-public information about an outcome is a violation, not an edge.

The states

Several states have challenged whether federal registration of a contract market pre-empts state gambling law, particularly for sports-related contracts, which by early 2026 made up the majority of volume on the largest US venue. The CFTC has argued in litigation that state actions intrude on an exclusive federal scheme, noting that a number of registered markets have collectively self-certified thousands of event contracts. Norton Rose Fulbright’s summary describes the market as at a crossroads between pre-emption, enforcement and rulemaking. The outcome will determine whether a contract listed on a federal venue can be traded by residents of every state.

• Federal: proposed rule on public-interest review of event contracts, comment and finalization pending
• Enforcement: first insider trading action in event contracts, venue-level discipline, an enforcement advisory
• States: litigation over pre-emption of state gambling law, with sports contracts the flashpoint
• On-chain: venues outside the federal framework, with their own enforcement history and access restrictions

What an institution can do

Treat venue eligibility as a legal determination rather than a trading one, made per venue and per fund vehicle and refreshed on every development. Confine activity to outcomes with objective, independent resolution sources, and to categories connected to the fund’s mandate, which excludes the sports contracts at the center of the state disputes. Assume that access to any venue or category can end before a position resolves, and size and document accordingly. The instruments are useful for hedging discrete event risk that price instruments cannot reach; the regulatory position is a reason to use them carefully, not a reason to ignore them.
