Kalshi Wins Federal Court Ruling in Sports Betting Fight

What This Means for Crypto Casino Players

For South African players, these proceedings are unfolding entirely within US jurisdiction and South African bettors are not directly subject to US state gambling law. The outcome will nonetheless be watched by regulators across emerging markets, including South Africa's National Gambling Board. Prediction market platforms including Polymarket already accept South African users, and a Supreme Court ruling classifying these contracts as financial instruments rather than gambling could influence how similar products are treated elsewhere. All crypto sports betting platforms available to South African players operate under international licences — typically Curaçao — and are not regulated by any South African authority.

The scale of the dispute makes clear why the case is attracting global attention. Kalshi collected R460 million in fees during just four days of March Madness wagering, with analysts forecasting the platform will handle R3.7 trillion in total wagers across 2026. Sports contracts make up more than 85% of all bets placed on Kalshi, so the legal classification of those contracts is not a peripheral question but the foundation of the company's entire commercial model.

The Federal vs. State Legal Divide

The dispute centres on whether prediction market wagers — where users stake crypto on the outcomes of sporting events, economic data releases, and other verifiable outcomes — are financial products regulated by the US Commodity Futures Trading Commission, or whether US states retain authority to classify and enforce them as gambling. The CFTC has openly backed Kalshi's position, creating the unusual circumstance of a federal regulator supporting a company being prosecuted by multiple state governments at the same time.

The Third Circuit court found that federal law overrides New Jersey's attempt to apply its betting statutes to Kalshi. The Ninth Circuit — whose jurisdiction covers Arizona, which has filed criminal charges against the platform — heard arguments this week and is broadly expected to rule against the company. Nevada, Washington State, Connecticut, and Illinois have also taken legal action against Kalshi. A dissenting judge in the Third Circuit wrote that “if it looks like gambling, talks like gambling, and calls itself gambling, it's gambling.”

A split between two federal circuit courts would ordinarily lead directly to Supreme Court review. Kalshi carries a current valuation of approximately R400 billion; its closest competitor, Polymarket, is valued at around R365 billion. Both platforms were built on the operating assumption that prediction contracts are regulated financial instruments — an assumption the Supreme Court will now be under pressure to confirm or reject.

What to Watch

The Ninth Circuit ruling is the next key development and will clarify whether a Supreme Court case is imminent. A separate legislative track is also advancing — US Congress members introduced a bipartisan bill in March that would reclassify crypto prediction bets as gambling regardless of how courts rule. South African players should note that any eventual US restrictions would apply only to US-domiciled platforms; internationally-licensed operators available to South African bettors would not be directly affected. With PSL football and the Springboks' domestic programme continuing through April, access to reliable crypto sports platforms remains a live concern for South African bettors this month.
