Hawaii Lawmakers Weigh Taxes On Kalshi Prediction Markets
Hawaii legislators are evaluating tax proposals and potential bans for federally regulated prediction market apps like Kalshi as tens of thousands of residents use the platform to wager on football and weather events. According to KHON2, the activity persists in Hawaii despite gambling remaining illegal in the state, drawing scrutiny from lawmakers who view the peer-to-peer trading model as a taxable loophole.
Prediction Markets Versus Traditional Casinos In Hawaii
Prediction market apps operate under a different legal framework than traditional state-licensed casinos or sportsbooks. Kalshi representatives told KHON2 that the platform functions similarly to a stock exchange rather than a house-banked casino, acting strictly as a middleman where users take contracts against other participants rather than wagering against the house. Because prediction markets are federally regulated, individual states receive zero tax revenue from transactions conducted within their borders. Users on prediction market apps must be at least 18 years old, whereas Hawaii casinos require individuals to be 21.
State lawmakers point out that this structure bypasses local prohibitions. Rep. Scot Matayoshi, D-Consumer Protection and Commerce Chair, described the platforms to KHON2 as a form of a loophole. Sen. Lynn DeCoite, D-Economic Development and Tourism Chair, stated that the apps are backdooring it and expressed that lawmakers are open to taxing the activity. Kalshi reported that it has 100,000 users in Hawaii, including 4,000 users who traded on weather contracts that businesses use as a hedge against weather disasters.
National Legal Pressure And State Legislative Plans
Hawaii lawmakers plan to examine legislation during the next session to either ban or regulate prediction market apps, according to KHON2. At least 14 other states are considering similar legislative measures.
Robert Denault, Kalshi Head of Enforcement and Legal Counsel, defended the model to KHON2, stating that the federal government recognizes peer-to-peer trading models as safer and better regulated at a nationwide level compared to traditional gambling operators. Kalshi representatives noted that the company is open to reasonable tax frameworks and will meet with state lawmakers later this year.
