[Polymarket Applies to List Parlay Trading for Sports Event Contracts in the U.S.] According to CoinDesk, prediction market provider Polymarket submitted a self-certification filing to the U.S. Commodity Futures Trading Commission (CFTC) on Wednesday, seeking approval to list parlay trading for sports event contracts in the U.S. (i.e., multi-condition combination prediction contracts). Polymarket describes this product as a combination of two or more underlying sports event contracts, where the contract can only settle at $1 if all predetermined sub-event outcomes are met; otherwise, it settles at zero. By adopting the self-certification approach, Polymarket is notifying the CFTC of its listing plans rather than seeking permission. The filing indicates that the listing will not occur before May 21, 2026. Another document reveals that Polymarket has requested the CFTC to keep related exhibits confidential due to commercial secrets.
