What This Means for Washington Traders
Because Kalshi is overseen by the Commodity Futures Trading Commission (CFTC) as a Designated Contract Market, its legality doesn't hinge on whether Washington has licensed sports wagering. Federal commodity regulation pre-empts the state-by-state patchwork for most of Kalshi's markets β but Washington has carved out sports event contracts, election and politics markets, and entertainment markets by court order in force since August 5, 2026, and that dispute is still in court.
On Kalshi you take a position by buying a contract priced between 1Β’ and 99Β’ β each cent represents one percentage point of implied probability. Contracts settle at $1 if the event happens and $0 if it doesn't, and you can exit early at the live market price. Profits are taxable income; Kalshi issues the relevant tax forms for Washington residents.
Sports-focused products like DraftKings Predict and FanDuel Predicts sports contracts aren't live in Washington yet. Which Kalshi market classes Washington residents can trade is set by the order described above. Polymarket's international book is closed to US persons; Polymarket US is a separate, narrower venue.
