Coinbase Moves New York Prediction Markets Fight to Federal Court

The Coinbase federal court prediction markets standoff with New York just got a new venue. Chief legal officer Paul Grewal said Wednesday the company removed New York Attorney General Letitia James’ lawsuit from state court to federal court, a procedural move that reframes the whole dispute around one question: who actually regulates event contracts, Washington or Albany?

Why Did Coinbase Yank the New York Case Out of State Court?

Short answer: because state court is hostile terrain and federal court is not. Grewal said on X that New York’s claims raise disputed and substantial questions of federal law and are subject to complete preemption, which is the legal trapdoor that lets defendants escape state venue when a federal statute fully occupies the field.

That is the polite version. The blunter read is that Coinbase does not want a New York judge applying New York gambling law to a product the company insists is already supervised by the Commodity Futures Trading Commission. Grewal has been consistent on this point, calling prediction markets federally regulated national exchanges under the CFTC and pledging to fight for the oversight Congress intended.

The removal does not kill the case. It relocates it. And relocation, in federal litigation, is half the war. The same legal chief laid out the strategy in Coinbase’s own launch announcement tied to the company’s nationwide rollout earlier this year, where Coinbase framed event contracts as financial instruments rather than bets.

We have removed this action to federal court. New York’s claims raise disputed and substantial questions of federal law and are subject to complete preemption.

What Letitia James Actually Filed

On Tuesday the New York AG dropped a complaint against Coinbase Financial Markets and Gemini Titan alleging that their prediction market offerings violate state gambling law. The hook for the AG is the user base. Her office says the two platforms allowed New Yorkers, including users between the ages of 18 and 20, to wager on sports, entertainment and elections without anyone securing a state gaming license first.

The remedies James is chasing are not symbolic. The complaint seeks fines, forfeiture of what she calls illegal profits, restitution for customers, and an injunction barring the companies from offering similar products in New York unless they comply with state licensing rules. You can read the petition filed against both exchanges on the AG’s public docket.

For context on how we got here, see our earlier coverage of the original complaint against the two exchanges. The filing this week is the state-court piece Coinbase just removed.

• Fines against Coinbase Financial Markets and Gemini Titan
• Forfeiture of profits the AG calls illegal
• Restitution for New York customers
• Injunction halting further prediction market offerings in the state

This Is Not a One-State Problem

Eleven states have now taken legal action against prediction market platforms, which tells you everything about how the map looks heading into the back half of 2026. State regulators want jurisdiction. Federal regulators say they already have it. Somebody is going to lose, and the loser will lose loudly.

The clearest federal counterpunch so far came on April 2, when the CFTC filed three separate complaints against state gaming regulators in Illinois, Connecticut and Arizona. The agency’s argument is direct: states cannot apply gambling laws or licensing regimes to event contracts that sit on CFTC-designated platforms. Period.

Six days later, on April 8, the CFTC teamed up with the Department of Justice and asked a federal court to block Arizona from enforcing its gambling law against Kalshi’s event contracts. That joint filing is the tell. When the DOJ walks into court alongside the CFTC, it is no longer a civil turf war between agencies and states. It is Washington drawing a line.

Prediction markets are federally regulated national exchanges, and we will continue to fight for the federal oversight of these markets that Congress intended.

What This Means for Coinbase, Gemini and Everyone Else

Coinbase launched prediction markets across all 50 US states on Jan. 28, including New York, offering trades on what it called any real-world outcomes spanning sports, politics and culture. That rollout was always going to attract this exact fight. Gemini’s Titan product landed in the same crosshairs almost immediately.

For Kalshi and Polymarket, the stakes are slightly different but pointed in the same direction. Both platforms are already dealing with trading halts in Nevada following court rulings, and Polymarket in particular has spent the last year trying to normalize event contracts with US regulators rather than go around them. If the Coinbase removal holds and the federal court agrees that preemption applies, it becomes the cleanest precedent the industry has.

The bigger question is whether Congress wants to settle this through legislation or let the courts draw the map first. The answer matters for more than prediction markets, as we covered in the broader regulatory fight over the Clarity Act, which runs on a parallel track with the same preemption themes.

Here is the uncomfortable truth that nobody in the industry wants to say out loud. A product that lets 18-year-olds bet on who wins the Super Bowl, framed as a commodity derivative, is not going to survive in every state regardless of which regulator signs the permission slip. The removal to federal court buys time and changes the judge. It does not change the politics.

What Happens Next

The first real test is whether the federal court agrees the case belongs on its docket. If it does, expect months of briefing on preemption, CFTC exclusivity and the definition of an event contract. If it remands the case back to New York state court, Coinbase is suddenly playing defense in a venue where New York gambling statutes are home turf.

Watch the CFTC’s Arizona case as the leading indicator. A win for the CFTC and DOJ there signals the federal preemption theory has legs. A loss, or a narrow ruling, and every state AG in the country starts drafting their own complaint by the end of the quarter.

Grewal says Coinbase will keep fighting. James says New York law applies. Somewhere between those two sentences is a billion-dollar product category waiting for a judge to pick a side.
