Are prediction markets legal in the US?
Yes, under federal law, on exchanges the CFTC has designated — Kalshi, Polymarket US, Novig, ProphetX and others. But states are fighting sports contracts in court, and orders in Nevada, Washington and Michigan already block some. Offshore sites such as polymarket.com exclude US residents altogether.

Novig review
A sports-only exchange that became a CFTC-designated contract market on 16 June 2026 (Ludlow Exchange, LLC, d/b/a Novig) and went nationwide on 4 August 2026, after two years as a state-licensed and then sweepstakes product. The fee model is the draw: makers pay nothing, pre-game straight trades are free for both sides, and takers pay a price-based fee only on live trades, futures and parlays. You must be 21 or older and physically in an eligible state; Novig says it does not operate in Arizona, Michigan or Nevada. Scored provisionally from its documents on four of nine criteria — we have not traded on it.

Polymarket US review
The US exchange that carries the Polymarket name — and a different company from polymarket.com. QCX LLC has been a CFTC-designated contract market since 9 July 2025 and clears through its own registered clearing house, so this is a dollar account with identity checks before the first deposit, not a crypto wallet. The fee is a published formula that peaks at $1.74 per 100 contracts at 50¢, with a maker rebate. Two things to know before signing up: the operator publishes no list of eligible states, and a Nevada court enjoined it there on 29 May 2026. Scored provisionally from its documents on four of nine criteria — we have not traded on it.

ProphetX review
A sports-first exchange designated by the CFTC on 11 June 2026 and live from 18 June, which also runs its own clearing house — traders face the exchange directly, with no broker in between. It charges 2% of net gains per market on straight trades rather than a per-contract fee, with rebates for high-volume makers. It says it is available nationwide but publishes no excluded-state list, and state regulators including Connecticut have reportedly ordered sports-contract operators to stop serving their residents. Political contracts were self-certified in September 2026. Scored provisionally from its documents on five of nine criteria — we have not traded on it.

Why a prediction market’s headline price is not your execution price

What a 23-platform prediction market documentation audit can tell you

Before comparing prediction market odds, compare the contract rules
Two contracts can have similar headlines and still settle differently. Use a five-part checklist before treating their prices as comparable.
