New York Just Sued Coinbase and Gemini for Running Illegal Sports Betting Markets — What It Means for Bettors

On April 21, 2026, New York Attorney General Letitia James filed separate lawsuits against Coinbase Financial Markets and Gemini Titan, alleging that both companies operated illegal gambling platforms under New York state law. The complaints were filed in Manhattan state court and represent the first major state-level enforcement action targeting prediction markets offered by major cryptocurrency exchanges.

The core of the AG’s argument is straightforward: these platforms let users bet on the outcomes of sporting events and other real-world happenings, outcomes that are determined by chance or factors beyond the user’s control. Under New York law, that is gambling. It does not matter, James argued, what the companies call their products. “Gambling by another name is still gambling, and it is not exempt from regulation under our state laws and constitution,” she said in a statement.

What Coinbase and Gemini Were Offering

According to the lawsuits, Coinbase’s prediction market platform allowed users to wager on outcomes like whether the New York Knicks would win a basketball game by more than 6.5 points, who would win the February 8, 2026 Super Bowl, and results of college basketball games including a February 14 matchup between St. John’s University and Providence College. Gemini offered similar contracts — including wagers on whether the New York Mets would win by more than 1.5 runs and who would win the Super Bowl.

Neither Coinbase nor Gemini holds a license from the New York State Gaming Commission. That is the central legal problem. Every licensed sportsbook operating in New York — and there are several — went through a rigorous licensing process, pays taxes on revenues, and operates under state oversight. These platforms, the AG contends, were doing the same thing without any of that accountability.

The Under-21 Problem and Triple Damages

The lawsuits also allege that both platforms allowed users between 18 and 20 years old to access their markets. New York law sets the minimum age for mobile sports betting at 21. This is not a technicality — it is a specific violation that carries its own legal weight and adds to the case for consumer harm.

James is seeking recovery of the platforms’ illegal profits, civil fines equal to three times those profits, and full restitution for affected customers. She also wants a court order prohibiting both companies from accepting wagers from anyone under 21 and banning them from marketing their platforms on college campuses. The potential financial exposure, given the triple-damages structure, is significant.

Coinbase pushed back immediately. A spokesperson said the company’s prediction market is a federally regulated national exchange registered with the Commodity Futures Trading Commission, and that the issue is already proceeding in New York federal court. “Coinbase will continue to fight for the federal oversight of these markets that Congress intended,” the spokesperson said. Gemini had not publicly commented at the time of the filings.

Is It Safe to Keep Using These Platforms?

This is the practical question for anyone who has been trading on Coinbase or Gemini’s prediction market products. The honest answer is that the legal picture is genuinely murky right now. The state is saying these are illegal gambling operations. The companies are saying they are federally regulated exchanges operating under CFTC oversight. Both things can be true simultaneously — the federal-versus-state jurisdictional question is legitimately unresolved and is now heading toward the courts.

What is clear is that operating in New York specifically carries the highest legal risk at this moment, given the active lawsuits and the AG’s stated intent to pursue enforcement. The under-21 age issue also means that some users may have claims for restitution under the lawsuit’s terms.

For bettors who want certainty — state-regulated platforms, licensed operators, and clear consumer protections — the existing licensed sportsbooks in New York are the straightforward alternative. They operate under the New York State Gaming Commission, pay state taxes, and have established responsible gambling programs in place. The prediction market products from crypto exchanges were always operating in a legal gray zone. That zone just got a lot more hostile in New York.

The Bigger Picture

This lawsuit does not exist in isolation. Separately, a bipartisan Senate bill introduced in March 2026 — the Prediction Markets Are Gambling Act — seeks to amend federal law to prohibit prediction contracts tied to sports and casino-style games on CFTC-regulated platforms. Multiple state attorneys general have signaled interest in similar enforcement approaches. The New York action is the first to actually land in court, which makes it the most concrete test of how these legal arguments will hold up.

The outcome of the Coinbase and Gemini cases will likely set significant precedent — either confirming that state gambling regulators have authority over prediction markets or establishing that federal CFTC oversight preempts state action. Either way, anyone with money on these platforms or who has been using them for sports wagering should be watching this case closely.
