New York Prediction Markets Lawsuit Targets Coinbase and Gemini

The New York prediction markets lawsuit landed hard on Tuesday. State Attorney General Letitia James accused Coinbase and Gemini of running what she called illegal gambling operations dressed up as financial contracts, escalating a fight that has already pulled in regulators from at least four other states. The suits, filed April 21, 2026, argue that the event contracts offered on both crypto exchanges are bets under New York law. Not swaps. Not securities. Bets.

What the New York Prediction Markets Lawsuit Actually Alleges?

The short answer: James’s office says the platforms are bookmakers, and she has the screenshots to prove it. Filings from New York Attorney General Letitia James describe users as bettors, describe each contract as a bet, and lean on the companies’ own marketing language to argue that these products are gambling by any honest reading.

The suit against Coinbase pulls no punches. It calls the offering “quintessentially gambling” and says it lets a user “stake or risk money upon the outcome of a contest of chance or a future contingent event not under the bettor’s control or influence.” That is the state gambling statute, almost word for word.

There is also the age issue, and it is ugly for both companies. New York bars anyone under 21 from gambling on mobile apps. The complaints say both platforms accepted wagers from users as young as 18. Three years of eligible customers, in other words, who should never have been in the funnel.

Gambling by another name is still gambling, and it is not exempt from regulation under our state laws and Constitution.

What the Coinbase Prediction Markets Complaint Actually Says

The Coinbase prediction markets complaint reads less like a financial regulator’s filing and more like a gaming commission brief. It walks through how the exchange advertised sports, entertainment, and election contracts, how it framed the platform to new users, and how that framing crossed into bookmaking territory.

Coinbase is not backing down. Chief Legal Officer Paul Grewal fired back on X within hours, writing that “prediction markets are federally regulated national exchanges” and that the company would fight for federal oversight. In other words, Coinbase’s defense is the preemption argument. If the Commodity Futures Trading Commission has jurisdiction, then New York does not, and the whole suit collapses on a constitutional question before any judge looks at gambling law.

That is the defense. Whether it survives contact with a New York courtroom is a different question. State judges have been unpredictable on this issue, and at least one federal panel has signaled skepticism about the preemption theory when the underlying contracts look exactly like sportsbook action.

Gemini Prediction Markets and the Silence from Winklevoss

Gemini prediction markets rolled out as a newer product line for the Winklevoss-led exchange, and on Tuesday the company declined to comment when asked about the suit. The silence is telling. Coinbase’s legal chief had a statement up before the ink was dry on the filing. Gemini chose to say nothing.

Part of that may be strategic. Gemini is still rebuilding trust with state regulators after years of enforcement headaches tied to its Earn product and its now-resolved fight with the SEC. Picking a high-profile fight with the New York AG on day one of a new lawsuit is the kind of move that plays badly with every other regulator watching.

The filings against Gemini mirror the Coinbase complaint almost point for point. Same age-gap allegations. Same argument that the contracts are bets. Same demand that the products be shut down in New York. The only real difference is tone, and that is mostly because Coinbase talked back and Gemini did not.

• Both complaints allege the platforms accepted users aged 18 to 20, below the state’s 21 minimum for mobile gambling.
• Both complaints cite the platforms’ own marketing copy, which described contracts in betting language.
• Both suits seek injunctions, restitution, and penalties under New York’s gambling and consumer protection statutes.
• Neither complaint names any individual executives as defendants, though that can change with amended filings.

The CFTC Is Already Fighting This Battle

Here is where the story gets larger than Coinbase and Gemini. CFTC Chairman Mike Selig has argued that prediction markets, sports contracts included, fall under his agency’s CFTC exclusive jurisdiction over prediction markets. That is not a throwaway talking point. The agency has gone to court to back it up.

The CFTC sued Arizona, Connecticut, and Illinois to stop those states from bringing cases against prediction market operators. It also joined a case out of Nevada on the side of the industry. New York, as of Tuesday afternoon, was not yet on that list, but the math is obvious. If the CFTC intervenes here too, the venue becomes federal, the questions become constitutional, and the gambling-law framing that James is leaning on gets a lot harder to sustain.

Multiple appeals courts are already chewing on versions of this question. Practitioners expect at least one of them to land at the U.S. Supreme Court before the end of 2027, which would finally settle whether event contracts are swaps under the Commodity Exchange Act or just bookmaking with a trading-screen skin on it.

Prediction markets are federally regulated national exchanges, and we will fight for federal oversight.

Why Kalshi Is Not on the Defendant List

Look closely at Tuesday’s filings and there is a name missing. Kalshi New York Gaming Commission lawsuit records show the company sued New York’s gaming regulator last fall, asking a federal court in the Southern District of New York to rule that state gambling laws do not reach its platform. That case is still pending.

Kalshi got there first. By filing its own suit before the state could file one, the company parked the fight in federal court on its preferred terms, with its preferred framing. That is why James went after Coinbase and Gemini on Tuesday and not Kalshi. Kalshi had already ring-fenced itself.

The lesson is not subtle. If you run a prediction market platform and you have not yet been sued by a state AG, filing a declaratory judgment action first may be the single smartest legal move on the board. Coinbase and Gemini did not do that. They are now playing defense instead of choosing the field.

What Happens Next for Traders and the Industry?

For users in New York, the immediate question is whether Coinbase and Gemini will voluntarily geofence the products while the suits play out. Neither company said they would on Tuesday, but that kind of operational change tends to happen quietly, in the app, without a press release. Check your contract positions.

For the industry, the bigger question is what the cumulative pressure from Nevada, Washington, New York, and the other states does to the economics of running these platforms. Sports contracts are where the volume is. If half the country’s population gets walled off, the business case for the product thins out fast, federal preemption or not.

And for the CFTC, this is the fight that defines the agency’s relevance in the crypto era. Selig has planted a flag. He either defends it in court across multiple jurisdictions over the next eighteen months, or he watches states quietly rewrite the rules on event contracts without his input. There is no middle path.
