What Maryland has done
Maryland is one of 7 states in active legal dispute with prediction-market operators over whether a federal CFTC designation displaces state gambling law. The Maryland Lottery and Gaming Control Agency has issued a cease-and-desist to prediction-market operators, and that dispute is now in litigation.
Maryland has issued a cease-and-desist to prediction-market operators and is one of the seven states in active legal dispute over federal pre-emption.
The state's argument is that offering event contracts on sporting and political outcomes to Maryland residents is gambling under state law, regardless of what the contracts are called federally. The operators' and the CFTC's argument is set out below.

The federal picture, briefly
Polymarket US lists event contracts on QCX LLC, a CFTC-designated contract market (DCM) with affiliated derivatives clearing organization (DCO). Polymarket acquired that licence by buying QCEX for $112 million in July 2025, reopened to US traders on 2 December 2025, and removed the iOS waitlist on 12 May 2026.
Operators and the CFTC argue the Commodity Exchange Act gives the CFTC exclusive jurisdiction over federally designated contract markets, pre-empting state gambling statutes. Several district courts have accepted that argument at the preliminary-injunction stage. No final appellate resolution as of August 2026.
Roughly roughly 43 of 50 states currently offer full-menu access to CFTC-regulated prediction markets.
Why this matters in Maryland
Maryland has legal online sportsbooks. Because the state already collects tax from licensed operators, it has a direct financial interest in how event contracts are treated — which is a large part of why the licensed-market states have been the most active on this issue.
Sports-betting status is included as background only. It is not legal advice, it changes, and it does not determine whether Polymarket US is available to you. Confirm with the Maryland Lottery and Gaming Control Agency and inside the app.
How access actually works
Two different venues, and the distinction matters more than anything else on this page:
- Polymarket US — the CFTC-regulated exchange. This is what US residents use. Available — no waitlist on iOS; Android is still rolling out behind a waitlist; there is no full web platform for US users yet. See app availability.
- The international exchange — non-custodial, settles in USDC on Polygon, and blocks US IP addresses. It is not an option from inside Maryland, with or without a workaround, and attempting one breaches its terms.
Not available to US residents — the international exchange geoblocks US IP addresses.
You appear to be in the US. Polymarket’s international exchange blocks US IP addresses — use Polymarket US, the CFTC-regulated exchange, instead. See what’s available in your state.
Maryland questions
Can I use Polymarket in Maryland right now?
Polymarket US operates nationally under its CFTC designation, so it is generally available in Maryland. However, the state disputes this, so availability can change — confirm in the app before funding. The international Polymarket exchange is a separate venue and blocks US IP addresses entirely.
Is trading on Polymarket a crime in Maryland?
We are not aware of any Maryland law that makes placing a trade on a CFTC-regulated event contract a criminal offence for an individual. State enforcement in this area has been aimed at operators, not customers. This is not legal advice; if the stakes matter to you, take advice locally.
Which regulator oversees this in Maryland?
Gambling in Maryland is overseen by the Maryland Lottery and Gaming Control Agency. Polymarket US, however, is regulated federally by the CFTC as a designated contract market — which is the source of the entire dispute: two regulators, two different classifications of the same product.
What are the alternatives in Maryland?
Kalshi is the other main CFTC-regulated venue and faces the same state-by-state disputes. PredictIt operates with a much narrower political-only market list. Maryland's licensed sportsbooks are regulated as gambling rather than as derivatives, which is a different legal product with different tax treatment. See our comparison of the alternatives.
