"Gambling by another name is still gambling, and it is not exempt from regulation under our state laws and Constitution." — Letitia James, Attorney General of New York
New York filed lawsuits on April 21, 2026 seeking a combined $3.4 billion in damages from Coinbase Financial Markets and Gemini Titan, alleging their prediction market platforms constitute unlicensed gambling operations under state law. The suits land in the middle of an escalating federal-state jurisdiction war over a prediction market industry that reached $21 billion in monthly trading volume in January 2026 — up 1,650% year-over-year — and now directly threatens the $17 billion licensed U.S. sports betting sector.
The core dispute is definitional. The Commodity Futures Trading Commission classifies prediction market contracts as federally regulated swaps. States classify them as gambling. A 2-1 Third Circuit ruling on April 6 sided with the CFTC. The Ninth Circuit appears poised to rule the opposite way. A circuit split would place the question before the Supreme Court as early as 2027. The outcome will determine whether a $37 billion-and-growing industry operates under federal derivatives law or state gaming commissions — and who captures the tax revenue.
For an industry that still derives 85-90% of its total value flows from subsidies rather than self-sustaining fee revenue, according to webthreepedia's foundational economic analysis, the prediction market sector is a rare case where genuine user demand is generating real transaction volume. Whether that volume represents legitimate derivatives trading or unregulated gambling is now a question for the courts.
Attorney General Letitia James filed two separate lawsuits on April 21, 2026, seeking minimum damages of $2.2 billion from Coinbase Financial Markets, Inc. and $1.2 billion from Gemini Titan LLC. The suits allege both companies operate unlicensed gambling platforms through their prediction market offerings, in violation of New York gambling statutes and the state Constitution.
The complaints cite specific contracts. Coinbase allegedly offered wagers on whether the New York Knicks would win by over 6.5 points, who would win Super Bowl LX on February 8, 2026, and outcomes of college basketball games including a February 14 matchup between St. John's University and Providence College. Both platforms allow users aged 18-20 to participate — a direct violation of New York's requirement that mobile gambling participants be 21 or older.
New York's disgorgement laws are particularly aggressive. The state can recover revenues deemed illegal not just from New York operations, but nationwide, potentially maximizing financial recoveries well beyond typical state enforcement actions. The AG seeks court-ordered fines, forfeiture of illegal profits, treble damages, and restitution to consumers.
Both companies launched their prediction market products in December 2025. Gemini Titan received its Designated Contract Market (DCM) license from the CFTC prior to launch. Coinbase Financial Markets operates under a separate regulatory structure. Both platforms are currently available across all 50 states.
Coinbase Chief Legal Officer Paul Grewal responded on X: "Prediction markets are federally regulated national exchanges," and stated the company would fight for federal oversight. Gemini declined to comment.
Notably absent from the lawsuits: Kalshi, the largest prediction market platform by U.S. market share, which preemptively sued the New York Gaming Commission in federal court in October 2025 after receiving a cease-and-desist order. That case remains pending in the Southern District of New York.
The prediction market sector's growth is difficult to overstate in raw terms. Monthly trading volume rose from approximately $1.2 billion in early 2025 to $21 billion in January 2026, according to TRM Labs — a 1,650% year-over-year increase. Monthly active wallets reached 840,000 unique participants by February 2026, tripling over the preceding six months.
Polymarket set a single-day volume record of $425 million on February 28, 2026. Prediction market transactions surpassed 192 million in March 2026, an all-time record.
Two platforms dominate. Kalshi holds approximately 52.6% U.S. market share with roughly $6 billion in 30-day volume as of mid-March 2026. Polymarket trails with approximately $9.7 billion in 30-day volume globally but a smaller U.S. footprint. Together, the two platforms accounted for 85-90% of total volume in 2025, per TRM Labs data.
Valuations reflect this growth. Kalshi's most recent valuation stands at $22 billion, up from an $8 billion valuation following a strategic investment by ICE/NYSE in October 2025. Polymarket is raising at a $15 billion valuation, a 43x increase from its $350 million valuation two years prior.
Sports contracts dominate the mix. Over 85% of all Kalshi bets are sports-related, according to Fortune. The Super Bowl 2026 generated over $1 billion in prediction market trading volume. A March Madness winner contract attracted over $100 million. During a four-day stretch of the NCAA tournament, Kalshi generated $25 million in platform fees alone.
User segmentation data from TRM Labs shows a maturing market: mid-frequency traders (11-1,000 trades) account for 44.7% of all trades and $869 million in volume. High-frequency market makers (10,000+ trades) contribute 35.2% of trades and $774 million in volume. Single-trade participants represent less than 0.2% of activity.
The legal battle is now being fought on multiple fronts simultaneously.
CFTC vs. States. On April 2, 2026, the CFTC filed lawsuits against Arizona, Connecticut, and Illinois, seeking declaratory judgments that federal law grants the CFTC exclusive regulatory authority over event contracts listed on registered designated contract markets. On April 10, the U.S. District Court for the District of Arizona granted a temporary restraining order barring the state from pursuing criminal charges against DCMs.
Third Circuit (Kalshi v. New Jersey). On April 6, 2026, a divided 2-1 panel of the Third Circuit held that the CFTC has exclusive jurisdiction over sports-related event contracts. The majority determined that Kalshi's sports contracts qualify as "swaps" under the Commodity Exchange Act because sports outcomes carry "potential financial, economic, or commercial consequence" for "sponsors, advertisers, television networks, franchises, and local and national communities." The ruling held that the CEA preempts New Jersey's gambling statutes through both field and conflict preemption.
Judge Jane R. Roth dissented, writing that the presumption against preemption applies strongly to historically state-regulated gambling activities. Roth argued that if a product "looks like gambling, talks like gambling...it's gambling."
Ninth Circuit (pending). Oral arguments suggest the panel favors the states' position, according to Fortune. An adverse ruling for prediction markets would create a direct circuit split with the Third Circuit.
State actions. Maryland and Massachusetts courts have ruled against prediction market platforms. Nevada, Washington, and multiple other states have filed similar suits. Prediction market companies have filed lawsuits against 11 states in total.
New York's separate path. The AG's April 21 lawsuits against Coinbase and Gemini were filed in state court, not federal court, potentially avoiding the federal preemption framework entirely. CFTC Chairman Mike Selig has argued prediction markets fall under his agency's "exclusive jurisdiction," but whether that argument holds in state court proceedings remains untested.
Congress is also engaged. On March 23, 2026, Senators John Curtis (R-UT) and Adam Schiff (D-CA) introduced the Prediction Markets Are Gambling Act (S.4160), the first bipartisan Senate bill seeking to restrict prediction markets. The legislation would amend the Commodity Exchange Act to prohibit CFTC-registered entities from listing contracts that resemble sports bets or casino-style games.
The bill's sponsors point to specific market dynamics. Prediction market sports contracts are listed in all 50 states, including states with restrictions or outright prohibitions on sports betting. These contracts generate no state tax revenue, evade state and tribal consumer protections, and undermine sovereign tribal regulatory regimes that were negotiated through decades of compact agreements.
The bill targets an asymmetry: licensed sportsbooks in 38 states and Washington, D.C. pay state taxes and comply with consumer protection requirements. Prediction market platforms operating under CFTC oversight do neither. The sponsors claim bipartisan support sufficient to clear both chambers, though no vote has been scheduled.
On the opposing side, the CFTC under Chairman Selig has signaled an expansion of federal rulemaking authority over prediction markets, including insider trading restrictions and enhanced market surveillance requirements.
The regulated sports betting industry has a direct financial stake in the outcome. U.S. sportsbooks generated $16.96 billion in revenue in 2025, according to the American Gaming Association, with more than $165 billion wagered across 35 states — an 11% increase in handle and 24% increase in revenue year-over-year.
New York alone accounted for nearly 16% of total U.S. handle, with $26 billion wagered in 2025. Illinois ranked second at $15.5 billion, New Jersey third at $12.2 billion.
Prediction markets now directly compete for the same customers. When Kalshi lists a contract on the Knicks covering a 6.5-point spread, the product is functionally identical to a spread bet at DraftKings or FanDuel — but offered without a state gambling license, without age-21 verification, and without state tax obligations.
The revenue projection gap is significant. The U.S. sports betting market is projected to reach $26.04 billion by 2030, growing at 7.07% CAGR. Prediction markets, if allowed to continue operating as federally regulated instruments, could capture a meaningful share of that growth without contributing to state tax bases that currently fund public services and problem gambling mitigation.
Flutter Entertainment (parent of FanDuel) saw its shares rise following introduction of the Curtis-Schiff bill, a market signal that traditional sportsbook operators view federal legislation restricting prediction markets as a positive catalyst.
From an economic value perspective, the prediction market sector exhibits characteristics distinct from most of the crypto ecosystem. The industry generates substantial fee revenue from actual user demand for a specific financial product.
Kalshi's $25 million in fees during a four-day March Madness stretch represents real revenue from real trading activity. Coinbase's consumer trading volumes of approximately $35 billion in Q1 2026 — though declining from $66 billion in January to $54 billion in March — reflect genuine transaction throughput.
The valuation question is whether these economics are sustainable under regulatory uncertainty. At a combined $37 billion valuation (Kalshi plus Polymarket), the sector trades at a premium that assumes continued access to sports markets across all 50 states. If state-level gambling regulation prevails, platforms would need to obtain licenses in each jurisdiction, comply with age and consumer protection requirements, and pay state taxes — a fundamentally different cost structure.
Polymarket faces an additional valuation overhang. Analysts have flagged that its volume figures may be inflated by airdrop farming in anticipation of a token launch. As one analyst noted: "Polymarket's volume is being read as pure product demand. Airdrop farming is why that read is misleading."
The transparency gap persists. Neither Kalshi nor Polymarket publishes audited financial statements. Revenue, cost structures, and profitability remain opaque — consistent with the broader crypto industry pattern of limited financial disclosure.
The prediction market industry has built genuine economic activity — $21 billion in monthly volume, 840,000 active participants, and real fee revenue — atop a regulatory classification that may not survive judicial review. The question is not whether these platforms process real transactions. They do. The question is whether contracts on Knicks point spreads and March Madness brackets are federally regulated swaps or state-regulated gambling.
The economic stakes extend beyond the platforms themselves. If prediction markets are gambling, states gain tax revenue, licensing fees, and consumer protection authority over a rapidly growing sector. If they are derivatives, the CFTC retains oversight of a product that happens to look identical to a sports bet, offered to 18-year-olds in states that require bettors to be 21.
The Third Circuit and Ninth Circuit appear headed toward opposite conclusions. Congress is split. The CFTC is suing states. States are suing platforms. New York is seeking $3.4 billion. The Supreme Court may ultimately decide. Until it does, a $37 billion industry operates in a jurisdictional gray zone — generating real volume, real fees, and real legal liability, with no certainty about which set of rules will ultimately apply.
