Read RSA 647:2 before assuming New Hampshire has nothing to say about Polymarket. The state's general gambling-offenses law defines “gambling” as risking something of value on a “future contingent event” for an agreed payout — a description that fits an event-contract trade closely enough that it reads like it was aimed at one, decades before Polymarket existed. Nobody in New Hampshire government has ever pointed it at Polymarket, but the words are sitting right there.

Is Polymarket Legal in New Hampshire? Start With RSA 647:2

New Hampshire has exactly one licensed gambling product built around a formal statute: sports betting under RSA 287-I, awarded as a sole-source monopoly to DraftKings through the New Hampshire Lottery Commission in 2019. That law defines an “authorized sports bettor” as 18 or older and physically present in the state, and voids any wager placed from outside New Hampshire under RSA 287-I:10, III. None of it mentions event contracts, because it was written for one company's sportsbook, not a category of product. The broader question lives in RSA 647:2 instead — Title LXII of the Criminal Code, the state's general gambling-offenses statute, which predates DraftKings, Kalshi, and Polymarket by decades and was never amended to carve any of them out.

The statute's own words: RSA 647:2 defines gambling as risking something of value “upon a future contingent event not under one's control or influence, upon an agreement or understanding that something of value will be received in the event of a certain outcome.” A class B felony attaches to a business that “accepts wagers exceeding $5,000 during any 30 day period on future contingent events.” Nobody has ever taken that language to court against Polymarket.

Which Polymarket? New Hampshire Still Splits Into Two Sites

Whatever RSA 647:2 might eventually mean, it applies differently depending which Polymarket a New Hampshire resident means. The international site, polymarket.com — USDC on Polygon, no KYC — has been geo-blocked for every US IP, New Hampshire included, since the 2022 CFTC settlement; that block is federal and has nothing to do with state law either way. Polymarket US, run by QCX LLC under CFTC designation and relaunched in December 2025, is the platform actually reachable from a New Hampshire address: KYC'd, dollar-funded, and unblocked by anything New Hampshire has done.

The Felony Clause Nobody Has Tested

A close read matters here. RSA 647:2's $5,000-per-30-days felony threshold targets a business that “conducts, finances, manages, supervises, directs, or owns” the gambling operation — the operator, not an individual trader placing contracts. A separate misdemeanor clause covers a person who simply “gambles,” which in theory could reach an individual user, though New Hampshire has no record of ever charging one for using a CFTC-regulated exchange. Polymarket's standing defense, identical to Kalshi's in every state fight this year, is that a federally designated derivatives contract isn't a state-law “wager” at all — a jurisdictional argument New Hampshire has simply never been forced to rule on, one way or the other.

What has and hasn't happened in New Hampshire:

  • No cease-and-desist letter to Polymarket or Kalshi
  • No Attorney General lawsuit or Lottery Commission action
  • No court ruling interpreting RSA 647:2 against an event-contract platform
  • New Hampshire did not sign the 44-state AG letter to the CFTC (July 2026) — one of only five holdouts
  • Polymarket US remains reachable from New Hampshire IPs as of this writing

Is Polymarket Legit and Safe in New Hampshire?

Legit: Polymarket US carries the same CFTC designation and KYC process in New Hampshire as everywhere else, and nothing in state records alleges a bad payout or fraud — the open question is jurisdictional, not whether the exchange honors a winning contract. Safe: mechanically, yes, an account opens today with no injunction in the way, but New Hampshire built its consumer protections — Lottery Commission oversight, self-exclusion, an 18-plus authorized-bettor age — around DraftKings specifically, and none of it extends to a platform the Commission has never reviewed.

A statute matching a product on paper isn't the same as a state enforcing it, and that gap could close the way it has in Massachusetts or New York. Trading event contracts can still lose the full stake regardless of how RSA 647:2 eventually gets read — it is not a way to make money. 21+ recommended; the National Problem Gambling Helpline, 1-800-522-4700, is free and confidential.
