New York AG Sues Coinbase and Gemini Over Prediction Markets, Seeks $3.4 Billion in Damages
New York Attorney General Letitia James filed separate lawsuits in Manhattan state court on April 21 against Coinbase Financial Markets, Inc. and Gemini Titan LLC, alleging both companies ran illegal, unlicensed gambling operations through their prediction market products.
The suits target two recently launched products: Coinbase "Predict," which went live in January 2026 through a partnership with event-contract exchange Kalshi, and Gemini Predictions, offered by Gemini Titan LLC after the firm secured a federal Designated Contract Market license from the Commodity Futures Trading Commission in December 2025, making Gemini the first crypto-native exchange to receive that designation. Both platforms allow users to place bets on outcomes ranging from election results and sports scores to economic indicators and entertainment events. Coinbase Predict sets a minimum bet of $1, a threshold the AG's office argues makes the product accessible to the broad retail market.
The AG's office is seeking a minimum of $2.2 billion from Coinbase and at least $1.2 billion from Gemini. Both suits also demand forfeiture of illegal profits, consumer restitution, and civil fines calculated at three times each company's earnings from the products. A court order banning either company from marketing prediction markets to college students is also requested.
What New York Says They Did Wrong
The lawsuits center on three specific allegations. First, neither company obtained a license from the New York State Gaming Commission, which the AG argues is required to offer gambling products and deprived the state of tax revenue that funds public schools, youth sports programs, and problem gambling services. Second, both platforms allowed users between 18 and 20 years old to participate; New York law sets the minimum gambling age at 21. Third, both companies allegedly accepted wagers on games involving New York college teams, which state sports betting law explicitly prohibits.
In framing the public interest stakes, the AG's office cited an NIH study linking early gambling exposure to increased rates of depression, anxiety, and financial stress, as well as an APA study finding that 32% of gambling disorder sufferers experience suicidal ideation. Both citations form part of the AG's official legal argument, underpinning the state's case that these products cause measurable harm to consumers.
AG James framed the action in direct terms: "Gambling by another name is still gambling, and it is not exempt from regulation under our state laws and Constitution."
Coinbase pushed back immediately. Chief Legal Officer Paul Grewal said the company intends to fight the suit, arguing that prediction markets operate under federal jurisdiction: "Prediction markets are federally regulated national exchanges registered with the CFTC. Coinbase will continue to fight for the federal oversight of these markets that Congress intended." Gemini did not respond to requests for comment.
A Federal-State Standoff With No Clear Resolution
The lawsuit lands in the middle of an active jurisdictional fight that has already produced conflicting signals from the courts. On April 6, 2026, the U.S. Third Circuit Court of Appeals ruled in Kalshi's favor, finding that the Commodity Exchange Act preempts New Jersey's state gambling law and that prediction market contracts qualify as federally regulated "swaps." That ruling was the first federal appellate decision on the question.
However, the Ninth Circuit has not yet ruled on Nevada's competing case, and legal analysts say the absence of a consistent ruling across circuits may require the U.S. Supreme Court to issue a definitive answer. New York, meanwhile, is not waiting. Its disgorgement laws allow the state to claw back revenues earned nationwide, not just within its own borders, which legal observers say makes this suit potentially more damaging than similar actions filed by Nevada, Washington, Illinois, Connecticut, Michigan, Massachusetts, Arizona, Tennessee, and other states over the past several months.
Market Numbers and Investor Reaction
The prediction market sector has grown sharply over the past year. Monthly trading volume across the industry reached $25.7 billion in March 2026, up from under $1 billion in mid-2025. Kalshi holds roughly 89% of the U.S. market by volume, according to Bank of America estimates, at approximately $13.1 billion per month. Polymarket, the blockchain-native platform that operates largely outside U.S. regulatory reach, accounts for roughly $10.6 billion. The remaining approximately $2 billion in monthly volume is distributed across other platforms, including Coinbase Predict and Gemini Predictions.
Coinbase Global (NASDAQ: COIN) shares fell approximately 6% following the announcement. The stock was already down around 18% for the year before the news broke. The company reports first-quarter earnings on May 7.
What This Means for Users in South Asia and Africa
For users outside the United States, the regulatory battle carries practical weight. Prediction markets have gained significant traction in South Asia and Sub-Saharan Africa, two of the fastest-growing regions for crypto adoption globally. India is Polymarket's most active non-U.S. English-speaking market, with contracts covering everything from RBI rate decisions to IPL outcomes. South Asia recorded roughly $300 billion in crypto transaction volume between January and July 2025, representing 80% year-over-year growth.
In Africa, Nigeria ranked sixth and Ethiopia ranked twelfth in the 2025 Global Crypto Adoption Index. Sub-Saharan Africa received more than $205 billion in on-chain value in the 12 months ending June 2025. Neither region has a formal regulatory framework for prediction markets, though broader regulatory momentum is building. Kenya signed its VASP Bill into law in October 2025, and Nigeria's Investment and Securities Act 2025 formally recognized digital assets as securities. Both developments signal active regulatory infrastructure construction in these markets, but neither addresses prediction markets specifically.
If the New York suits succeed and force Coinbase or Gemini to restrict access to their prediction market features, global liquidity on those platforms could be affected. Blockchain-native alternatives like Polymarket, which runs on Polygon and settles in USDC, would likely absorb displaced users seeking permissionless access. More broadly, the core legal question being litigated in U.S. courts (whether prediction markets are financial instruments or gambling products) is the same question that regulators in Nairobi, Lagos, Accra, and Karachi will eventually have to answer.
What Comes Next
The two cases will proceed through New York state courts while federal litigation continues in parallel across multiple circuits. Legal analysts tracking the issue widely anticipate that a U.S. Supreme Court resolution may be needed to settle the question definitively. For Coinbase, the timing is difficult: the lawsuit adds regulatory pressure ahead of its May 7 earnings call, at a moment when the stock is already under significant pressure. How courts draw the line between a financial derivative and an illegal bet will shape not only which platforms survive in the United States, but which regulatory templates the rest of the world borrows from.
