In most states. Sports event contracts on federally designated markets such as Kalshi are offered under federal commodities law, but several states dispute this in court. Whether states can regulate sports event contracts is contested: at the preliminary-injunction stage the Third Circuit sided with Kalshi (April 6, 2026), while the Ninth (August 28, 2026) and Sixth (September 25, 2026) Circuits ruled Kalshi is unlikely to show federal law blocks state gambling laws. Three Supreme Court petitions are filed (Nos. 26-299, 26-338 and 26-344); none granted yet.
Each contract settles at $1 if the outcome happens and $0 if it does not, so a price of 38c is the market's read on a 38% chance. You can sell before settlement at the prevailing price.
