Prediction markets

Event contracts are regulated federally by the CFTC rather than state by state, so a CFTC-designated exchange can be available where no state sportsbook licence exists. Availability still varies: individual exchanges apply their own geofences, and pending litigation has changed access in several states at short notice.

Kalshi is not currently accessible from Washington in our coverage. Polymarket, ProphetX, OG Markets are; availability is subject to change, so verify before signing up.
