Kalshi have spent a year beating state regulators in court. New York just ended the run.
US District Judge Analisa Torres, the same judge who decided the Ripple case, denied Kalshi's request to block New York from enforcing its gambling laws against their sports contracts.
Kalshi's core legal argument is that federal commodities law overrides state gambling law. One CFTC licence, valid in all 50 states, with no state gambling taxes.
Torres said no. There is a strong presumption against federal preemption in areas states have always policed, and gambling is one of them. She also weighed New York's interest in preventing addiction and protecting sports integrity 'heavily' over Kalshi's.
That preemption argument is the foundation the whole sector is built on. If it fails for sports contracts, every state gets a say, and the single-licence model starts to crack.
Kalshi filed an appeal to the Second Circuit within days and is separately fighting a push to halt their operations in Washington state entirely. With federal wins in Nevada and New Jersey pointing one way and New York now pointing the other, this is how questions reach the Supreme Court.

Goldman Sachs have banned employees from betting on prediction markets tied to finance: specific companies, elections, economic data and geopolitics. Morgan Stanley say their staff code of conduct already covers prediction-market betting, and Bank of America are restricting trades on company-specific, economic and financial-services events.
The fine print is very Goldman. Sports and entertainment bets are still allowed. Repeat offenders face dismissal, and improper gains above $200 can be clawed back or sent to charity.
In May, the CFTC and DOJ charged a Google employee with using inside knowledge of Google's 'Year in Search' rankings to win Polymarket bets, the first event-contract insider-trading case involving a private company. Governments are moving the same way: Chicago is advancing a ban on city staff trading on private information, Arizona barred state employees, and House Democrats want federal judges out of the markets altogether.
A market on whether a company beats earnings is a parallel equity market without an insider-trading statute. Prediction markets are now big enough that every compliance department in America has an opinion about them.

Polymarket want Americans to trade predictions with borrowed money.
On 3 July, they filed with the National Futures Association to register an affiliate as a futures commission merchant, the licence that allows customers to trade on margin. The CFTC still has to approve the rulebook changes.
Margin means putting down a fraction of a position's value instead of the whole thing.
For the platform, it multiplies volume per dollar of customer deposits. For traders, it multiplies both sides of the bet. Kalshi already offer it, and in a two-giant race, matching the rival's offerings is table stakes.

Prospect Markets have signed a letter of intent with OG Broker, a registered futures broker related to Crypto[dot]com, to offer sports event contracts to US customers.
The plan: list the contracts on Nadex, the CFTC-registered exchange behind OG Prediction Markets and Crypto[dot]com's US derivatives arm, with OG Broker handling the clearing.
The target launch is Q3 2026. Worth being clear: the letter of intent is non-binding, and definitive agreements and regulatory approvals still stand between here and live markets.
Crypto[dot]com just lost DraftKings as a tenant when DKeX went live this month.
Renting their licence and rails to smaller entrants is the answer: if you cannot keep the biggest client, become the landlord for everyone else. A US licence is the scarcest asset in this sector, and it is now available to rent.
