What This Means for California Traders
Because Kalshi is overseen by the Commodity Futures Trading Commission (CFTC) as a Designated Contract Market, its legality doesn't hinge on whether California has licensed sports wagering. Federal commodity regulation pre-empts the state-by-state patchwork, and California is contesting that pre-emption in court over sports event contracts β access is unchanged unless a ruling says otherwise.
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 California residents.
Sports-focused products like DraftKings Predict and FanDuel Predicts sports contracts aren't live in California yet. Kalshi remains the widest regulated market set for politics, economics, and weather contracts. Polymarket's international book is closed to US persons; Polymarket US is a separate, narrower venue.
