Hawaii’s position

Hawaii bans all forms of gambling and has no legal sports betting. But, as Civil Beat reports, its gambling law carves out bona fide business transactions such as futures contracts, which Civil Beat calls the “loophole” prediction markets rely on.

In 2026, HB 2198 would have added prediction markets to Hawaii’s definition of gambling. Per Civil Beat it passed the House but never got a Senate hearing, and its sponsor plans to try again. Attorney General Anne Lopez signed the October 2026 states’ brief asking the US Supreme Court to take up a Kalshi case. See is Kalshi legal?
