A split between federal appeals courts has put the legality of prediction market sports bets in the hands of the U.S. Supreme Court, with New Jersey challenging the CFTC's authority over platforms like Kalshi
The battle over who controls the future of crypto-powered sports betting in the U.S. has reached a critical juncture. New Jersey is asking the Supreme Court to decide whether states or federal regulators get the final say on prediction market contracts tied to sporting events-a move that could reshape the legal landscape for platforms like Kalshi and their users nationwide.
Conflicting Court Rulings
At the heart of the dispute is a direct clash between two federal appeals courts. In April 2026, the Third Circuit ruled that the Commodity Exchange Act, enforced by the Commodity Futures Trading Commission (CFTC), overrides New Jersey's gambling laws when it comes to sports contracts on federally registered prediction markets. But just days before New Jersey's Supreme Court petition, the Ninth Circuit reached the opposite conclusion, finding that Nevada's state authority over sports betting is not preempted by the same federal law. This circuit split has created legal uncertainty for prediction market operators and state regulators alike.
New Jersey's 332-page petition, filed by Attorney General Jennifer Davenport and gaming enforcement interim director Mary Jo Flaherty, argues that the Dodd-Frank Act does not strip states of their power to regulate sports betting-even when those bets are offered on CFTC-registered platforms. The state contends that classifying sports bets as "swaps" under federal law does not give the CFTC exclusive jurisdiction, especially when states have established their own frameworks to address compulsive gambling, underage betting, and market integrity.
Kalshi's Nationwide Ambitions
Kalshi, a federally registered prediction market, has positioned itself as a nationwide financial exchange subject to CFTC oversight. The company has pushed back against New Jersey's legal campaign, stating that it cannot operate under 50 different state regimes and remains confident in the lower court's ruling. Kalshi's business model relies on offering contracts that let users bet on the outcomes of real-world events, including sports games, with the company arguing that federal regulation should suffice for legal operation across the U.S.
New Jersey, however, points to enforcement actions by at least 20 state gaming authorities against similar platforms, arguing that companies like Kalshi are sidestepping state laws and consumer protections. The state's petition claims that dozens of states, regardless of political leaning, have opposed the idea that prediction markets can bypass local gambling rules simply by registering with the CFTC.
Regulatory Stakes and Industry Impact
The Supreme Court's decision on whether to hear the case could have sweeping consequences for the crypto betting industry, state regulators, and users. If the Court sides with the Third Circuit, federally registered prediction markets could gain a green light to offer sports contracts nationwide, potentially undermining state-level gambling restrictions. If the Court upholds the Ninth Circuit's view, states would retain broad authority to regulate or ban such products within their borders, forcing platforms to navigate a patchwork of local laws.
The CFTC, led by Chair Michael Selig, has continued to assert exclusive jurisdiction over prediction markets, even suing several states and proposing a formal regulatory framework for the sector. Yet the agency itself acknowledged that the circuit split now "calls out for resolution" by the Supreme Court. The justices are not required to take the case, and may wait for more lower court decisions before intervening, but the current legal uncertainty is already affecting how platforms, users, and regulators approach prediction market sports betting.
Market Data and Enforcement Trends
According to public enforcement records, at least 20 U.S. states have initiated civil actions against prediction market operators for alleged violations of state gambling laws since 2024. The CFTC's own regulatory proposals for prediction markets remain in draft form as of June 2026, with no final rules adopted. Meanwhile, the volume of sports-related contracts traded on federally registered prediction markets has grown steadily, but remains a small fraction of the broader U.S. sports betting market, which exceeded $100 billion in legal wagers in 2025 based on American Gaming Association data.
Prediction markets operate at the intersection of financial regulation and gambling law, creating unique challenges for both companies and regulators. Unlike traditional sportsbooks, prediction markets often frame their contracts as financial instruments rather than pure wagers, seeking federal oversight to avoid state-by-state licensing. This legal ambiguity has made the sector a flashpoint for regulatory conflict, with the outcome of the Supreme Court petition likely to set a precedent for how crypto-powered betting platforms are treated across the country.
While the Supreme Court's involvement is not guaranteed, the current standoff exposes the limits of federal preemption in the face of entrenched state interests. The CFTC's aggressive assertion of authority, combined with Kalshi's push for nationwide access, has forced a reckoning over who truly controls the rules for crypto-enabled sports betting. For users, operators, and regulators, the next move from the Supreme Court will determine whether prediction markets become a federally sanctioned alternative to state-licensed sportsbooks-or remain mired in legal limbo.
