Hawaii Gambling Ban Challenged: 100,000 Users Trading on Prediction App Kalshi

A sharp political wind is currently blowing in Hawaii, directly impacting the growing prediction market industry. While all forms of gambling are strictly prohibited in the Aloha State, apps like Kalshi have built a massive user base. Around 100,000 Hawaii residents are already active on the platform, causing significant unrest in the Honolulu Capitol given the strict local laws. The debate centers primarily on whether these digital marketplaces, where users bet on election outcomes, weather, or pop culture events, should be classified as illegal gambling or modern financial trading.

The situation is particularly volatile because Hawaii, along with Utah, is one of the few US states without any legal gambling offerings. No casinos, no lottery, no legal sports betting. Nevertheless, business is booming on citizens' smartphones. Especially during the football season, where over $35 billion is legally wagered nationwide, people in Hawaii are turning to alternatives. Providers cleverly argue based on their structure, which differs fundamentally from traditional bookmakers.

Numbers and facts

The dimensions are impressive. Kalshi reports 100,000 active users in Hawaii alone. Of these, about 4,000 users have specifically bet on weather contracts. An interesting example of the financial impact was provided by a speech by Governor Josh Green in January. When he used terms like "homeless" or "tourism," online bettors raked in about $450,000. Political figures are also highly sought after. Users are currently betting on whether the embattled Lieutenant Governor Sylvia Luke will step down before September 1.

A significant difference from casinos is the minimum age. While US casinos usually require one to be 21, Kalshi allows access starting at 18. The company does not see itself as a gambling provider, but as a middleman. Robert Denault, Head of Enforcement and Legal Counsel at Kalshi, emphasizes the safety of the model:

"The federal government has recognized for a long time that these peer-to-peer trading models are safer and better when they’re regulated at the nationwide level and much different than state-licensed casinos or gambling operators who really exist just to take user profits." - Robert Denault, Head of Enforcement/Legal Counsel at Kalshi

Background

The core of the dispute lies in the legal classification. Traditional sports bets are placed against the house. Kalshi, on the other hand, acts like an exchange where contracts are traded between private individuals. The company itself has no financial interest in the outcome of the bets, merely collecting fees. This structure means the platforms are regulated at the federal level and provide no tax revenue to individual states. This is a thorn in the side of Hawaii lawmakers.

Representative Scot Matayoshi called the situation a kind of loophole. Senator Lynn DeCoite clearly demanded that these activities be taxed. She argues that without revenue, the state has no funds to help people with gambling addiction problems or to conduct prevention work. Kalshi has already signaled a willingness to talk and plans to meet with lawmakers at the end of the year to discuss a reasonable tax framework. At the same time, 14 other US states are considering similar laws to curb the growth of prediction markets.

Why it matters for German players

For German players, the situation in Hawaii serves as a warning about unregulated gray markets. In Germany, the legal situation is very clear through the State Treaty on Gambling 2021 (GlüStV 2021). Anyone wishing to bet or play safely in this country should strictly look for the whitelist of the Joint Gambling Authority of the States (GGL). In contrast to the USA, where prediction markets often operate in a legal gray area, strict player protection rules are active in Germany. These include the cross-provider deposit limit of 1,000 euros per month and monitoring by the LUGAS system.

Betting on the outcome of political elections or social events, as is booming with Kalshi in Hawaii, is not permitted in German online casinos with a GGL license. Here, the focus is clearly on virtual slot games, poker, and sports betting under strict conditions, such as the 1-euro limit per spin for slots. German users should stay away from offers without a GGL license, as neither payment security nor data protection according to German standards is guaranteed there.

What it means for GGL-licensed casinos

The development shows that interest in alternative betting markets is rising. GGL-licensed casinos in Germany must continue to focus on their core offering and comply with strict regulatory requirements. While taxes for such peer-to-peer models are now being discussed in the USA, German providers already pay high taxes and invest heavily in player protection. The Hawaii case illustrates that authorities worldwide are trying to better control the digital space to avoid tax losses and strengthen consumer protection. For licensed providers, this means long-term greater legal certainty against illegal competitors.
