Event derivatives are contracts that allow market participants to speculate on, or hedge against, the outcome of a discrete event, such as an election, a sports match, an economic data release, or whether an underlying futures contract settles above or below a specified price threshold.

History

Event derivatives, also referred to in U.S. regulatory parlance as event contracts, are typically structured as binary instruments whose payoff can be expressed as a fixed amount if a specified condition is satisfied at expiration and zero otherwise. The CFTC describes an event contract, also called a prediction or information contract, as a derivative whose payoff is based on a specified event, occurrence, or value, such as a macroeconomic indicator, corporate earnings, level of snowfall, or dollar value of damages caused by a hurricane. While the CFTC's definition is broad enough to cover continuous-valued or damage-based measures, many event derivatives listed on regulated markets are structured as cash-settled binary options in which a fixed settlement amount is paid if a contract expires in the money and zero if it expires out of the money.

Event derivatives differ from conventional options and futures in that their payoff does not scale with the magnitude of a price move or the severity of an event. A standard option's payoff depends on how far the underlying price moves beyond a strike, while an event derivative pays a fixed sum regardless of whether the triggering condition is crossed by a small or large margin. This all-or-nothing characteristic makes event derivatives useful for expressing discrete probabilistic views, for hedging binary exposures, or for aggregating information as a form of prediction market, in which the contract price is interpreted as an implied probability of the referenced outcome.

From Over-the-Counter Origins to Exchange Listing

Event derivatives were historically associated with bilateral, over-the-counter arrangements, such as customized wagers on election outcomes or sporting events. Regulated exchange listings have substantially supplemented that structure. CME Group (CME) lists Chapter 23 "Event Contracts" on its CME, COMEX and NYMEX designated contract markets, structuring them as cash-settled, European-style options on futures that are traded on the CME Globex electronic trading platform and subject to the general rules of the exchanges and the Commodity Exchange Act. KalshiEX LLC was designated a contract market by the CFTC on November 3, 2020, and lists CFTC-regulated event contracts for trading as swaps on its exchange. These developments indicate that a substantial portion of the modern event derivatives market operates within regulated exchange infrastructure rather than purely bilateral arrangements.

Regulatory Framework

Event contracts in the United States are governed by the Commodity Exchange Act (CEA) and CFTC regulations. Regulation 40.11 prohibits event contracts that reference terrorism, assassination, war, gaming, or any activity unlawful under state or federal law, or any activity the CFTC determines by rule to be contrary to the public interest. This provision applies to event contracts listed on designated contract markets and covers both futures and options contracts, as well as swaps listed on such markets. Listing an event derivative on a designated contract market also subjects it to the CEA's core principles, which require that a market not be readily susceptible to manipulation and that it maintain adequate financial resources and surveillance systems.

Product Development at CME Group

CME Group's Chapter 23 Event Contracts span multiple asset classes. CME lists Event Contracts on E-mini Standard & Poor's 500 index futures, E-mini Nasdaq-100 futures, E-mini Russell 2000 futures, Euro/U.S. Dollar foreign exchange futures, and Bitcoin futures, while COMEX lists Event Contracts on gold, silver and copper futures, and NYMEX lists Event Contracts on light sweet crude oil futures. CME certified the initial listing of Event Contracts on Bitcoin futures for trading on CME Globex effective March 13, 2023, describing them as daily-expiring, cash-settled, European-style options on futures with a fixed payout of $20 if a contract expires in the money and $0 otherwise. A similar filing in 2022 introduced Event Contracts on E-mini S&P 500 futures with the same $20 fixed-payout structure. In November 2025, CME, CBOT, NYMEX and COMEX announced Hourly Event Contracts tied to E-mini S&P 500 futures at fixed times during the trading day, effective December 8, 2025, on CME Globex.

Kalshi and the Expansion of Regulated Event Swaps

KalshiEX LLC's designation as a contract market in November 2020 followed CFTC review of the exchange's application and a technical evaluation of its operational capabilities against the core principles of Section 5(d) of the CEA. On January 17, 2025, the CFTC granted Kalshi's petition to modify its designation order to permit intermediated futures trading, broadening its product scope beyond event contract swaps. On September 22, 2023, the CFTC issued an order disapproving congressional-control political event contracts self-certified by Kalshi, which had proposed cash-settled binary contracts based on which political party would control a chamber of Congress; the CFTC found the contracts involved gaming and activity unlawful under state law and were contrary to the public interest.

Usage & Key Users

Exchange-traded event derivatives at CME Group are structured as cash-settled, European-style, premium-style options on futures that expire at the daily settlement price of the principal contract month of an underlying futures contract. A call contract pays its fixed settlement value if the underlying futures settle strictly above the strike price, and a put contract pays its fixed settlement value if the underlying futures settle at or below the strike price; otherwise, the contract expires worthless. Settlement values vary by product: CME's equity index and foreign exchange Event Contracts are quoted from $0 to $1.00 with a $1.00 in-the-money settlement value, COMEX and NYMEX Event Contracts are quoted from $0 to $100 with a $100 settlement value, and CME's E-mini S&P 500 and Bitcoin Event Contracts carry a $20 fixed payout under their respective rule filings. Long positions pay the full premium upfront and their maximum loss is limited to that premium, while short positions receive the premium and bear a maximum loss equal to the fixed settlement value minus the premium received.

CME also maintains a separate Chapter 22, "Event Contract Swaps," for binary contracts referencing discrete external events, such as macroeconomic data releases or central bank decisions, rather than the settlement price of an existing futures contract. CME's event contract specifications describe contingency procedures for delayed or rescheduled data releases, including extended trading windows and rules for resolving strikes to "no" if an event does not occur by a contingency expiration date. Trading of Hourly Event Contracts and daily Event Contracts on CME Globex uses a first-in, first-out matching algorithm, and event-based contracts on CME Globex are supported on a near-continuous schedule that includes weekends and holidays for certain products.

Underlying futures liquidity provides context for event contracts referencing cryptocurrency prices. CME's Bitcoin futures had an average daily volume of 11,200 contracts in 2023, up 4 percent from 2022, and average open interest of 16,500 contracts, up 28 percent, with large open interest holders averaging 112, up 22 percent from 2022. In the fourth quarter of 2023, Bitcoin futures average daily volume rose to 12,900 contracts, up 27 percent versus the prior quarter, with open interest averaging 20,400 contracts. These figures pertain to the underlying futures contracts rather than to the Event Contracts themselves, but they illustrate the liquidity base supporting cryptocurrency-linked event derivatives.

Participants in exchange-listed event derivatives markets include proprietary trading firms, institutional investors, asset managers, and retail speculators seeking small-notional, short-term exposure to daily or intraday price thresholds without the capital commitment of a full futures position. KalshiEX LLC lists CFTC-regulated event contracts for trading as swaps on its designated contract market, and the CFTC has stated it holds exclusive jurisdiction over such contracts traded on Kalshi's exchange.

Risk Management

Settlement of exchange-listed event derivatives is tied to objectively determined reference values, typically the daily settlement price of an underlying futures contract's principal contract month, which is intended to reduce susceptibility to manipulation at expiration. If a market disruption prevents the exchange from establishing a reliable daily settlement price on an expiration date, final settlement of the affected Event Contracts is deferred until a settlement price can be determined, even though trading in the contracts ceases at the originally scheduled expiration. Designated contract markets listing event derivatives must also satisfy the CEA's core principles, including requirements that contracts not be readily susceptible to manipulation and that the exchange maintain surveillance procedures to detect abusive trading practices.

Controversies

CFTC Regulation 40.11 categorically prohibits event contracts referencing terrorism, assassination, war, gaming, or activity unlawful under state or federal law, reflecting concern that certain event derivatives could be economically equivalent to gambling products regulated at the state level. The CFTC applied this provision on September 22, 2023, when it disapproved congressional-control political event contracts self-certified by Kalshi, finding that the proposed contracts involved gaming and activity unlawful under state law and were contrary to the public interest. The decision established that binary contracts referencing election outcomes are not automatically permissible on regulated exchanges, even when structured as swaps listed on a designated contract market.

A separate controversy involves jurisdictional conflict between state and federal regulators. On August 11, 2026, the CFTC issued an emergency order after Kalshi reported a market emergency arising from a pending motion by the State of New York for a temporary restraining order that would have prohibited Kalshi from offering event contracts from its principal place of business in New York. The CFTC asserted that the CEA confers exclusive federal jurisdiction over swaps traded on designated contract markets and directed Kalshi to continue operating in accordance with its normal practices and the CEA's core principles pending resolution of the state action. Public records reviewed for this article do not describe specific enforcement cases involving manipulation of settled event derivative prices; available coverage centers on the Regulation 40.11 disapproval and the state-federal jurisdictional dispute described above.
