CFTC-regulated prediction markets (event contracts) are available to Hawaii residents 18+ through federally regulated exchanges such as Kalshi and Polymarket. Because they’re regulated federally rather than by the state, they’re one of the few real-money options available even where sportsbooks and online casinos are not — covering politics, economics, sports and culture.
Sweepstakes casinos are available in Hawaii under the federal dual-currency (Gold Coins / Sweeps Coins) sweepstakes model — a free-to-play way to win redeemable prizes, with no purchase necessary to enter or win. You must be 18+ (some platforms require 21+).
Statewide mobile sports betting, real-money online casino (slots, table games) and online poker are not legal in Hawaii, and would require new state legislation to change. Be wary of offshore sites that claim to offer them — they are unlicensed, unregulated, and offer no consumer protection.
