Court history for Hawaii
The rulings and actions shaping Kalshi's status in Hawaii, oldest first.
- April 2026. The Third Circuit rules 2-1 for Kalshi in New Jersey: sports contracts are swaps under federal law, and federal law overrides state gambling law.
- August 28, 2026. The Ninth Circuit rules 3-0 for Nevada: Kalshi's sports contracts are gambling under state law, not federally regulated swaps. The ruling binds federal courts across the Ninth Circuit.
- September 2, 2026. New Jersey asks the US Supreme Court to review the Third Circuit ruling. The two circuits now disagree, the kind of split the Supreme Court exists to settle.
- September 25, 2026. The Sixth Circuit holds that Ohio and Tennessee can regulate Kalshi's sports contracts, joining the Ninth Circuit against Kalshi.
Why states fight Kalshi
Kalshi holds a federal license from the CFTC. Several states say Kalshi's sports contracts are gambling, and gambling belongs to the states. Federal appeals courts split on the question:
- For Kalshi: the Third Circuit, for New Jersey, in April 2026.
- Against Kalshi: the Ninth Circuit for Nevada on August 28, 2026, and the Sixth Circuit for Ohio and Tennessee on September 25, 2026.
- Pending: the Fourth Circuit for Maryland, argued May 7, 2026, and New Jersey's petition to the Supreme Court, filed September 2, 2026.
A split between circuits is the classic path to the Supreme Court. Until then, your access depends on where you live and on any court order in your state.
