On 31 July 2026 New York Attorney General Letitia James and Governor Kathy Hochul filed a civil suit in New York County Supreme Court against KalshiEX, LLC — a CFTC-licensed prediction-market platform — seeking at least $36 billion in damages, triple restitution of illegal gains, a $100,000 fine per unauthorised wager offer and a full shutdown of Kalshi's activity in the state as an unlicensed gambling operation. Kalshi denies the state's jurisdiction and invokes federal preemption under the Commodity Exchange Act.
Prediction markets — platforms where users trade event contracts such as «candidate X will win» or «team Y will win the match» — have boomed since 2024, when they outperformed traditional polls in forecasting the US presidential election. Kalshi presents itself as a derivatives exchange licensed by the federal Commodity Futures Trading Commission (CFTC), not a gambling platform. States counter that when a user stakes money on an uncertain outcome, it is a wager. With Friday's filing New York becomes the fifth state to formally challenge Kalshi's status, following Nevada, New Jersey, Massachusetts and Maryland.
We see the $36 billion demand not as a routine regulatory action but as an escalation designed to set precedent. The headline number combines three components: triple restitution of Kalshi's New York profits, a $100,000 penalty per single unauthorised wager offer, and consumer restitution. Whether or not the court awards the full sum, calculating the exposure at that scale means the AG's office is treating every contract on every election and every sporting event as a separate violation of New York's gambling law.
The second axis is age. Under the complaint, Kalshi accepted wagers from users aged 18–20, while the minimum gambling age in New York is 21 — the same threshold licensed sportsbooks are fined for breaching. Kalshi also listed markets on New York college teams, which state law explicitly bars for all licensed bookmakers. The combination of «underage users + college markets» gives the AG the most straightforward factual hook and connects the case directly to the broader logic behind the tighter KYC flow at casinos and betting platforms.
The third front is constitutional. Kalshi invokes federal preemption: if the CFTC certified it as a Designated Contract Market under the Commodity Exchange Act, states arguably cannot regulate the same contracts as gambling. States reply that a derivative contract on «will the NY Giants win Sunday?» carries none of the hallmarks of a commodity future — it is a wager dressed up as a contract. This is the case that will most likely end up at the US Supreme Court and settle the fate of the whole prediction-market sector.
For European and Ukrainian players the key question is not who wins in US courts but what precedent this sets for the next wave of blocking orders. In July 2026 ANJ in France and ADM in Italy already blocked Polymarket; other jurisdictions — Germany's GGL, Sweden's Spelinspektionen, the Dutch KSA — are watching the US cases closely, and the parallel EU AMLA consultation on AML obligations for gambling is heading in the same direction. Ukraine's PlayCity blocked Polymarket back in January 2026; an equivalent decision on Kalshi is a question of timing rather than precedent, particularly against the backdrop of the broader UKGC money-laundering risk assessment.
What exactly did New York file against Kalshi on 31 July 2026?
On 31 July 2026 the New York Attorney General's Office filed a civil suit in New York County Supreme Court against KalshiEX, LLC, asking the court to enjoin its operations, order at least $36 billion in damages — including triple profits, a $100,000 fine per unauthorised wager offer and full disclosure of customer data — and force full restitution. The suit was filed in coordination with Governor Kathy Hochul. New York becomes the fifth state to formally challenge Kalshi's prediction-market status, after Nevada, New Jersey, Massachusetts and Maryland.
Why is Kalshi classified as illegal gambling in New York State?
Under the complaint Kalshi offers wagers on uncertain future events — from sports matches to presidential elections and cultural events — and charges a commission that depends on the outcome. That fits the definition of gambling in §225.00 of the New York Penal Code. Kalshi never obtained a state gambling licence and never paid gambling taxes. On top of that, the platform accepted wagers from users aged 18–20 (New York's minimum age is 21) and listed markets on state college teams, both of which are explicitly barred for licensed bookmakers.
Who regulates prediction markets — the states or the US federal government?
This is the constitutional conflict that makes the case landmark. Kalshi holds a CFTC (Commodity Futures Trading Commission) authorisation as a Designated Contract Market for derivatives trading and invokes federal preemption under the Commodity Exchange Act. States reply that a bet on the winner of an election or a football game is not a commodity future, and that the Tenth Amendment leaves gambling regulation to the states. The dispute is likely to reach the US Supreme Court, and its ruling will define the future of the entire prediction-market sector in the US.
What does this mean for players in Europe and Ukraine?
There is no direct legal impact on European or Ukrainian players — Kalshi is officially unavailable in most EU jurisdictions and Ukraine's PlayCity blocked the platform back in January 2026. The precedent, however, matters: if US courts rule that prediction markets are gambling, that will strengthen European regulators' hand in their own cases against Polymarket and similar platforms and will likely shape upcoming decisions from the GGL, KSA and Spelinspektionen. Players who use VPNs to sign up for unlicensed prediction markets risk having withdrawals blocked and losing all consumer protections.
As of 4 August 2026, the only lawful route into prediction markets for players in Ukraine, the EU and the UK is a platform licensed by your own jurisdiction's regulator. In the UK, several UKGC-licensed bookmakers accept political-event markets; in Italy, France and Germany online political-event contracts are prohibited; in Ukraine oversight sits with PlayCity. Do not use a VPN to register at Kalshi or Polymarket from a European IP — the platform can freeze your account and funds once it detects a geolocation mismatch, and the same rules of thumb from choosing a reliable licensed casino apply to prediction markets.
We expect the New York v. Kalshi case to run for 12–24 months, with a probable appellate cycle through the federal courts and, ultimately, the US Supreme Court. Whatever the final ruling, the 2026 trend is already clear: regulators in both the US and the EU are hardening the «prediction market equals gambling» position and demanding either a licence or an outright block. Online casino play, sports betting and prediction markets are for adults (18+) and are not a way to earn income; if you feel the gambling budget slipping out of control, use GAMSTOP (UK), Cruks (NL), OASIS (DE), RUA (IT), Spelpaus (SE), the ANJ register (FR), autoexclusão SPA (Brazil) or your national helpline.
