Law banning sports prediction markets enacted in 2026?

This market will resolve to "Yes" if any bill with the effect of banning CFTC-regulated prediction markets from offering sports betting contracts is signed into law by December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No". Any bill that prohibits federally regulated prediction markets from offering sports betting contracts, or otherwise places such activities under state-level gambling regulation rather than federal regulatory oversight, will qualify for a “Yes” resolution. Qualifying legislation may include joint resolutions and must pass both the House and the Senate, and must be signed by the President, become law without signature while Congress remains in session, or become law through veto override. Presidential pocket vetoes that expire resolve to "No". The primary resolution source for this market will be official information from the US federal government and the Commodity Futures Trading Commission (CFTC); however, a consensus of credible reporting will also be used.

How trading works

Polymarket uses a central limit order book (CLOB) model — you can buy or sell shares of any outcome at the current market price, or place limit orders at your target price. All positions are settled in USDC when the market resolves.

Resolution

Markets resolve through UMA's Optimistic Oracle. After the market closes, a proposer submits a resolution, followed by a 2-hour dispute window. If no dispute is raised, the resolution is accepted. Disputed markets go to UMA token holder vote.
