Polymarket filed to list combinatorial outcome contracts (also known as parlays) in U.S. sports event contracts via a self-certification filing with the Commodity Futures Trading Commission. The proposed combinatorial outcome contracts would combine two or more distinct underlying contracts into a single position and settle only if all legs meet their specified outcomes. The filing states Polymarket intends to list these contracts no earlier than May 21, 2026, in U.S. sports event markets.
Polymarket’s proposed combinatorial outcome contracts combine two or more underlying contracts into a single position, with each contract consisting of multiple legs that reference individual event outcomes as defined in the filing. These contracts are structured to settle only if every leg resolves to the specified outcome, creating an all-or-nothing payoff where final settlement depends on the collective results of the component legs rather than on the outcome of any single leg.
The Contract resolves to $1.00 if and only if every leg is satisfied.
If any single leg is not satisfied, the Contract resolves to $0.00, regardless of the outcomes of any remaining unsettled legs.
Polymarket’s proposed combinatorial outcome contracts combine two or more underlying contracts into a single position that references multiple event-specific legs, with settlement dependent on the collective outcomes of those legs. The filing states that “Every outcome must be satisfied for the Contract to resolve to $1.00,” and specifies, “The Contract resolves to $1.00 if and only if every leg is satisfied.” The document further states the alternate resolution condition: “If any single leg is not satisfied, the Contract resolves to $0.00, regardless of the outcomes of any remaining unsettled legs.” The filing frames the contracts as contingent instruments that settle only on full satisfaction of all component legs.
Polymarket filed to list combinatorial outcome contracts with the Commodity Futures Trading Commission via self-certification, meaning the company does not seek explicit permission from the CFTC before listing. The filing states Polymarket intends to list these contracts “no earlier than May 21, 2026.” The submission also included a separate exhibit filed under a confidentiality request that Polymarket said contains possible trade secrets or other commercial information and related materials submitted.
Polymarket plans to list combinatorial outcome contracts and intends to offer them no earlier than May 21, 2026. Those plans come amid ongoing regulatory review and scrutiny of prediction markets by the SEC and the CFTC, along with examination by Congress, the courts, state regulators and gambling firms. The filing occurs while regulators consider the implications of novel products and possible ETF structures tied to event contracts.
