New York put a number on Kalshi on Friday, and the number is $36,000,000,000.00. That is the compensatory damages line in the state's verified petition, written out to the cent, followed by the phrase "at minimum pending accounting." Attorney General Letitia James filed it in New York County Supreme Court. Kalshi has spent the past six weeks telling investors the company is worth $40 billion.
Those two figures sit within 10% of each other. One is a fundraising target reported in June. The other is what a single state says it is owed.
New York's claim outruns the on-chain market beside it
Chainalysis published its World Cup report this week and the headline travelled everywhere: $20 billion in prediction market volume tied to the tournament, measured from January 2026 through the final. Roughly 400,000 wallets took part. Every outlet ran it.
New York's petition asks for almost twice that, from one company.
The comparison is not apples to apples, and nobody should sell it as one. Chainalysis measures on-chain flows, which means Polymarket and its neighbours, settled in stablecoins. Kalshi is a CFTC-designated contract market and its order book does not live on a public chain, so that $20 billion leaves Kalshi out entirely. What the juxtaposition does show is scale. A state attorney general has asked for a sum that exceeds the entire measurable on-chain wagering market for the largest sporting event on earth, and she wants Kalshi to pay it.
Kalshi's own numbers give the demand some footing. The platform cleared roughly $31 billion in trading volume in June alone, with sports contracts making up about 87% of its annual volume. Three million users signed up during the World Cup. Disgorgement of gains at that run rate, calculated across a national customer base rather than New York residents alone, stops being a rounding error very quickly, and the petition asks for exactly that.
Where the $36 billion is built from
The petition does not present one lump. It stacks four demands against Kalshi, and the largest runs open-ended by design.
| What New York asks for | Amount |
|---|---|
| Compensatory damages, stated in the petition | $36,000,000,000.00, minimum, pending accounting |
| Penalty per unlicensed sports wagering offer or attempt | $100,000 |
| Multiplier on alleged gains under New York Penal Law 80.10 | Three times |
| Minimum age Kalshi permitted | 18 |
| New York minimum for mobile sports wagering | 21 |
Watch the $100,000 line. It attaches per offer rather than per user or per settled contract, and on a venue that lists thousands of sports markets and refreshes them through a tournament season, the multiplication does the work against Kalshi. The state also wants an accounting of customer bets, customer losses and company gains. That is how "at minimum" ends up in a damages line.
James put the legal theory in one sentence. "No matter what they call themselves, prediction markets like Kalshi are gambling platforms, plain and simple." The petition adds that Kalshi accepted users aged 18 to 20 in a state that sets 21 as the floor for mobile sports wagering, and that it listed markets on New York college teams, which licensed sportsbooks are barred from touching.
CFTC lawyers reached the courthouse first
The federal regulator did not wait for an invitation. The CFTC filed an emergency motion for a temporary restraining order against New York's enforcement before the state's petition landed, and outlets put the gap anywhere from thirty-six minutes to a full day. Chairman Michael Selig framed it as a procedural objection. New York, he said, chose to "force an unprecedented sudden shutdown" instead of seeking answers from the courts, and the agency "has already sued to stop this."
The argument underneath is the Commodity Exchange Act. The CFTC holds that its jurisdiction over registered exchanges is exclusive and that state gambling statutes give way where a designated contract market is concerned. The agency made the same case in an amicus brief in a separate Ohio proceeding. Kalshi moved the New York matter to federal court, the Southern District of New York. Head of communications Elisabeth Diana said states "can't just shut down a federally licensed exchange," warning that the shutdown would push New Yorkers offshore.
That claim has already been tested once this month and lost. A federal judge denied Kalshi's attempt to block New York's regulators on July 7, three weeks before the petition. The state's Gaming Commission had already sent Kalshi a cease-and-desist in October. Michigan, Nevada, Washington and Massachusetts have active actions of their own, and a New York win would give all four a template. This is the same federal-versus-state collision we covered in April when Washington moved against state gambling regulators, only now the sums have a comma count that changes the calculation for everyone involved.
The report the industry cited all week cuts both ways
Prediction market advocates spent the week pointing at the Chainalysis figures as proof of a maturing asset class. Read past the headline and the same report hands New York its evidence.
Of the $20 billion, only $5.7 billion changed hands during the five-week tournament itself. Traders built the rest as positioning over the preceding months. World Cup markets accounted for around 63% of all prediction market volume while the tournament ran, meaning the category's record quarter was mostly one football competition. Daily volume climbed from roughly $50 million before the opening match to about $250 million in the first week and past $300 million for the Spain versus Argentina final.
Then there is the market that keeps getting quoted in the trade press: $49 million riding on whether Cristiano Ronaldo would cry when Portugal went out. He did. The yes side collected. It is difficult to describe that contract as price discovery on a real-world risk, and it is exactly the listing a gaming regulator reaches for when it calls the information-market framing a costume.
The participant data is less flattering still. Chainalysis found 55% of bettors finished the tournament in profit, and 79% of those winners were experienced traders. Retail money sat on the other side of that trade, and Kalshi is not the venue Chainalysis measured, though its sports mix looks much the same. Roughly 3,700 wallets, under 1% of the total, carried illicit transaction histories, and at least $5.4 million reached betting wallets from Huobi and HTX, which the United Kingdom sanctioned in May. Those are small percentages of a large number, which is the sort of statistic that reads as clean compliance in a research post and as a finding in a complaint.
Worth remembering that the on-chain side settles in stablecoins, and June set a record for stablecoin volume partly on the back of this activity. The 400,000 wallets Chainalysis counted are a narrow slice of the population who actually hold crypto in 2026, which makes the concentration of winnings among practised traders more legible.
Kalshi went out for the $40 billion round in June, weeks after closing $1 billion, nearly doubling the price in under two months. Whether that price survives a docket in the Southern District of New York is the question the next few weeks answer. The removal fight comes first, then the preemption argument, then whichever of the four other states moves next.
