Is Kalshi legal in New York?

Yes, for now. Kalshi, Polymarket US and Novig all operate in New York, sports included, and Novig is the official prediction market partner of the Mets. But New York is the state with the most moving parts: the attorney general put out an industry alert on January 30, 2026, the CFTC responded by suing the state pre-emptively, a proposed class action against Kalshi is pending in Manhattan federal court, and a bill called the ORACLE Act would tighten oversight. None of it has changed what you can trade yet. Status as of October 15, 2026.

The legal picture

New York legalised online sports betting in 2022 and taxes it at 51% of revenue, the highest rate in the country. Prediction markets offer the same games at 18+ with a small exchange fee and no state tax, which is why the state and its licensed operators care. The sequence so far:

  • November 2025: a proposed class action is filed in the Southern District of New York alleging Kalshi runs unlicensed sports betting.
  • January 30, 2026: the attorney general issues an industry alert on prediction markets.
  • Following that: the CFTC sues New York pre-emptively to defend federal jurisdiction over event contracts.
  • 2026 session: the ORACLE Act is proposed in the legislature to tighten oversight and potentially prohibit some contract types.

No court has ordered any platform to geofence New York. The federal pre-emption question that decides all of this is now in front of the Supreme Court via New Jersey's petition, filed September 2, 2026, with Kalshi's response due in November.

What to do

  • Trade on any of the three platforms today.
  • If you're 18–20, Kalshi and Polymarket are your only regulated options for sports in New York; sportsbooks and Novig are 21+.
  • Watch the CFTC v. New York case and the ORACLE Act; we'll update the page on any order or enactment.

Questions people ask

Is Polymarket legal in New York?

The Polymarket US app is available in New York. Some trackers call the state a grey area because of the attorney general's position, but there is no order blocking the app as of October 2026.

Why is New York different from Texas or Florida?

New York already has a licensed, heavily taxed online sports betting market, so prediction markets compete with it rather than fill a gap. That gives the state and its licensed operators a reason to push back, and the AG has.

What is the ORACLE Act?

A proposed state bill that would tighten oversight of prediction markets and could ban certain contracts. It's a proposal, not law, as of October 2026.

What's the class action?

A proposed class action filed in the Southern District of New York in November 2025 alleging Kalshi offers unlicensed sports betting. It's pending; it doesn't affect availability unless and until a court orders something.
