Polymarket Nevada: The State That Sued It, Not Just Kalshi

Read enough of these state pages and a pattern sets in: Kalshi gets the lawsuit, Polymarket gets a footnote. Nevada breaks that pattern on purpose. A Carson City judge named QCX LLC — the company behind Polymarket US — in its own preliminary injunction, making Nevada one of the only states where Polymarket isn't riding along on someone else's court case.

Is Polymarket Legal in Nevada? Judge Woodbury Said No, By Name

Nevada has regulated sports betting longer than any other state, and its rules leave less room for a workaround than most. Under NRS Chapter 463, the Nevada Gaming Control Board (NGCB) and Nevada Gaming Commission require every mobile or online sportsbook to be tied to a licensed, physical casino — there is no such thing as a standalone online betting license here. That structure is why Nevada moved first: the NGCB sent Kalshi a cease-and-desist notice on March 4, 2025, more than a year before most other states opened a file. Kalshi sued, won a temporary reprieve in federal court, then lost it when the Ninth Circuit rejected its preemption argument in February 2026. On April 3, 2026, Carson City District Judge Jason Woodbury granted the NGCB a preliminary injunction against Kalshi, comparing an event contract on a baseball game to a $100 bet on the Dodgers and calling the two "indistinguishable."

Nevada Has Now Gone After Four Companies

Kalshi and Polymarket aren't the only names in Nevada's enforcement file. Robinhood, which offered Kalshi-linked sports contracts through its own app, was sued by the NGCB and agreed in November 2025 to stop operating in the state while litigation continued. Coinbase launched its own prediction-market product and drew a Nevada cease-and-desist letter and lawsuit in February 2026. Reporting on the Polymarket ruling in June 2026 called it the third such injunction Nevada regulators had secured in a matter of months. Four different companies, one state gaming board, the same core argument each time: a wager on a game outcome is a wager on a game outcome, whatever a federal agency calls the wrapper.

Why the Casino-Only Rule Matters Here

In states without Nevada's licensing structure, the argument over prediction markets is mostly about federal preemption — whether a CFTC designation shields a company from a state gambling statute that was written with sportsbooks like DraftKings and FanDuel in mind. Nevada's statute doesn't leave that much daylight. Every legal sportsbook here operates under a casino's license, full stop, and neither Kalshi nor Polymarket is tied to a Nevada casino at all. That gap is a big part of why Judge Woodbury ruled the way he did twice in two months.

Is Polymarket Legit and Safe in Nevada?

Legit, as a company: Polymarket US (QCX LLC) is a CFTC-designated exchange running KYC accounts and dollar settlement, and nothing in Nevada's case accuses it of shorting a payout — this fight is about licensing, not fraud. Safe, in Nevada specifically: no, and not in the vague sense other states use that word. There is an active court order with QCX LLC's name on it, issued by the same judge who already ruled against Kalshi, in a state that has now pursued four different prediction-market and crypto operators through its courts. Kalshi's parallel Ninth Circuit appeal remains open, and Nevada's congressional delegation has moved to push the underlying question to Congress instead of waiting on state-by-state rulings — but none of that changes what the injunction says today.
