Prediction market provider Polymarket filed a self-certification with the Commodity Futures Trading Commission (CFTC) on Wednesday to list "combinatorial outcome contracts" — effectively parlays for sports event contracts. The filing describes these contracts as combining two or more underlying contracts, requiring all legs to be satisfied for a $1.00 payout; otherwise, the contract resolves to $0.00. Since the contract is self-certified, Polymarket is informing the CFTC of its intent to list the products no earlier than May 21, 2026, rather than seeking explicit permission. Separately, SEC Chairman Paul Atkins announced the agency is exploring exchange-traded funds (ETFs) around prediction markets, noting that novel products raise novel questions and that the staff will seek public input. Prediction markets have faced increasing scrutiny from Congress and courts, particularly regarding sports-related contracts, with state regulators and gambling firms arguing they infringe on states' rights to regulate gambling. The CFTC maintains its oversight authority under the Commodity Exchange Act, while the Supreme Court is expected to address the issue.
