Kalshi Wins Federal Court Ruling in Sports Betting Fight
A US federal appeals court ruled in Kalshi's favour last week, blocking New Jersey from enforcing state gambling laws against the crypto-linked prediction market platform. The Third Circuit decision creates a direct conflict with a separate federal court that heard opposing arguments about the same legal question — a split that analysts expect will require the US Supreme Court to settle whether crypto prediction markets are financial derivatives or unlicensed gambling operations, likely by 2027.
What This Means for Crypto Casino Players
Canadian players who access prediction market platforms are watching this US legal battle for signals about how regulators elsewhere may respond. While Kalshi and Polymarket are US-focused platforms operating under CFTC oversight, Canadian crypto sports bettors use international platforms that accept wagers in Bitcoin, Ethereum, XRP, and other digital assets. A Supreme Court ruling classifying prediction contracts as financial derivatives could accelerate similar arguments in Canada, where federal and provincial authorities both claim jurisdiction over gambling products.

The commercial stakes show why this case is attracting attention beyond US borders. Kalshi reported C$34 million in fees from a single four-day March Madness window, with analysts projecting C$274 billion in total wagers across the platform this year. Sports contracts represent more than 85% of all bets placed on Kalshi, making the gambling classification question central to the company's entire operation.
The Federal vs. State Divide
The central question is whether prediction market contracts — where users wager crypto on sports outcomes, economic data releases, and other verifiable events — are federally regulated commodity swaps under the Commodity Futures Trading Commission, or whether US states can enforce their own gambling laws against the same products. The CFTC has backed Kalshi, arguing that prediction contracts are financial derivatives governed exclusively by federal statute, and the Department of Justice filed in support of that position.
States take the opposite view. Arizona filed criminal charges against Kalshi. Nevada's Gaming Control Board won a temporary court order halting the platform's sports contracts earlier this year. Washington State joined the opposition with a lawsuit in March 2026. Connecticut, Illinois, and New Jersey have also moved against the company. One dissenting judge wrote that “if it looks like gambling, talks like gambling, and calls itself gambling, it's gambling.”
The Ninth Circuit — which covers Arizona — heard arguments this week and is widely expected to rule against Kalshi, creating the appellate split that typically triggers Supreme Court review. Kalshi's current valuation stands at approximately C$30 billion; Polymarket, the competing platform, is valued at around C$27 billion. Both companies built their business models on the legal premise now under simultaneous challenge in multiple US federal courts.
What to Watch
The Ninth Circuit verdict is the immediate next marker. A ruling against Kalshi makes a Supreme Court case near-certain given the circuit conflict. A bipartisan congressional bill introduced in March would classify crypto prediction bets as gambling regardless of how courts decide, adding a parallel legislative track. Canadian players should monitor whether the US outcome prompts discussions at the Alcohol and Gaming Commission of Ontario or other provincial regulators, as similar classification questions around crypto prediction markets have not yet been formally addressed in Canada. With the NHL playoffs underway, crypto sports bettors are particularly active this month and should ensure their chosen platforms remain accessible in their jurisdiction.
