Is Polymarket Legal in the US? All 50 States (Oct 2026)

Is Polymarket legal in the US? Yes — through Polymarket US, a separate CFTC-regulated exchange that is legal at the federal level. It is open to US residents on iOS, Android and the web with full KYC, after the waitlist was dropped in May 2026. The international exchange at polymarket.com remains close-only for US IP addresses: existing positions can be closed, but no new trades can be opened.

The United States has the most complex Polymarket situation of any country. The international exchange is close-only for US users — positions can be closed, but no new trades opened — while a separate CFTC-regulated US exchange launched in December 2025, and is now caught in a fierce battle between federal regulators, state gambling commissions, and the courts.

Quick status — last updated October 2026:

• International exchange (polymarket.com): Close-only for US IP addresses — no new orders, though existing positions can be closed. No US signups.
• Polymarket US exchange: Waitlist removed in May 2026 — now open to US users on iOS, Android and the web (web still in beta). CFTC-regulated, full KYC required.
• Your state matters: Polymarket says trading is unavailable in Nevada, where a court order is in force. Minnesota’s ban is enjoined and not in force. Nine states have sent cease-and-desist letters or sued, without a court order against Polymarket so far — see the state table.
• Also available: Kalshi (CFTC-regulated) — a longer-established US venue with fiat funding.

Is Polymarket Legal in My State? (All 50 States)

Federal CFTC approval makes Polymarket US legal nationally, but it has not settled the question at the state level. Nevada is the only state where Polymarket itself says trading is unavailable (its App Store listing: “Trading currently unavailable in NV”), and Nevada is also the only state with a court order in force against Polymarket. Polymarket doesn’t publish any other restricted-state list.

Several states have sent Polymarket cease-and-desist letters or sued it, mostly over sports event contracts. As of October 2026 none of those actions has produced a court order against Polymarket outside Nevada, and Minnesota’s outright ban has been enjoined by a federal court, so it is not in force.

How to read this table (checked October 24, 2026): “Available” means Polymarket’s own listings don’t exclude the state. The app checks your location and can switch off individual market categories state by state (sports most often), so a state marked Available may still hide some markets. You must be 18, or your state’s age of majority where it is higher: 19 in Alabama and Nebraska, 21 in Mississippi. State actions come from regulators’ releases, court records and news reports.

The legal picture is unusually fluid: states argue prediction markets are unlicensed gambling, while the CFTC is suing states (Arizona, Connecticut, Illinois, Kentucky, Minnesota, New York and Wisconsin) on the grounds that federal law preempts them. Courts have reached conflicting conclusions, and New Jersey’s case is now before the Supreme Court.

Current Status: Close-Only International, Open US Exchange

The international Polymarket exchange — the one with deep liquidity, no KYC, and wide market variety — is close-only for US IP addresses: existing positions can be closed, but no new trades can be opened. This has been the case since Polymarket’s 2022 CFTC settlement.

A separate Polymarket US exchange launched on December 2, 2025 with CFTC approval. After six months of invite-only access, Polymarket removed the waitlist in May 2026 — the app is now open to US users without an invite code, live on iOS and Android with the web version in beta.

The Regulatory Timeline

Polymarket’s US journey has been a rollercoaster:

2022: The CFTC Settlement

In January 2022, the CFTC ordered Polymarket (Blockratize, Inc.) to pay a $1.4 million penalty for operating an unregistered facility for event-based binary options. Polymarket was required to wind down non-compliant markets and cease US operations. The CFTC noted Polymarket’s “substantial cooperation” in reducing the penalty.

2024: The FBI Raid

On November 13, 2024, the FBI raided CEO Shayne Coplan’s New York apartment, seizing his phone and electronic devices. The DOJ was investigating whether Polymarket was allowing US users to trade on the international platform in violation of the 2022 settlement.

2025: DOJ Declines, QCEX Acquired, CFTC Approval

• July 2025: DOJ and CFTC formally ended their investigations without bringing charges. Polymarket received declination notices from both agencies.
• July 2025: Polymarket acquired QCEX (a CFTC-licensed derivatives exchange and clearinghouse) for $112 million, providing the regulatory foundation for a legal US return.
• October 2025: Intercontinental Exchange (ICE), the parent company of the NYSE, invested up to $2 billion in Polymarket at an ~$15 billion valuation.
• November 2025: The CFTC granted Polymarket an Amended Order of Designation, allowing it to operate as a fully regulated US platform.
• December 2025: The Polymarket US app launched — invite-only.

2026: State-Level Legal Challenges

While Polymarket won at the federal level, state gambling regulators are fighting back:

• Nevada: The Gaming Control Board sued in January 2026. A preliminary injunction on May 29, 2026 bars Polymarket from offering sports, election and entertainment contracts in Nevada.
• Tennessee: The Sports Wagering Council sent cease-and-desist letters to Polymarket, Kalshi and Crypto.com in January 2026. On September 25, 2026 the Sixth Circuit vacated Kalshi’s injunction against the state.
• Massachusetts: A judge barred Kalshi’s sports contracts in January 2026. Polymarket then sued Massachusetts pre-emptively (February 2026), arguing the CFTC has exclusive jurisdiction; that case is stayed.
• Connecticut: Sent cease-and-desist orders to Kalshi, Robinhood and Crypto.com in December 2025, and to Polymarket and eight other platforms on September 10, 2026.
• Illinois: Sent Polymarket a cease-and-desist on January 27, 2026, calling its activity illegal gambling.
• Arizona: Filed 20 criminal counts against Kalshi (not Polymarket) for illegal gambling.
• Later in 2026: Wisconsin (April), Rhode Island (May), Kentucky (June) and New York (September) sued Polymarket; Missouri (September) and Ohio (October) sent cease-and-desist letters, and Polymarket sued Ohio in response.

Outside Nevada, none of these actions has yet produced a court order against Polymarket. Courts have reached conflicting conclusions on whether federal CFTC approval preempts state gambling laws — this will likely need to be resolved by higher courts.

2026: MLB Deal and CFTC Rulemaking

• MLB named Polymarket as its exclusive prediction market exchange partner in a multi-year deal with access to official data feeds.
• The CFTC issued an Advanced Notice of Proposed Rulemaking soliciting public input on new prediction market rules.
• A bipartisan Senate bill — the “Prediction Markets Are Gambling Act” — was introduced to ban sports event contracts on CFTC-regulated platforms.
• April 2026: In a notable role reversal, the federal government (CFTC) sued Connecticut, Arizona, and Illinois, arguing that prediction markets fall under exclusive federal jurisdiction and that the states’ cease-and-desist actions are preempted.

2026: Waitlist Dropped and Minnesota’s Ban

• Polymarket removed its US waitlist around mid-May 2026, roughly six months after launch, opening the app to US users without an invite code. It has since expanded to iOS, Android and the web.
• Minnesota became the first state to pass an outright ban on prediction markets. Governor Tim Walz signed a law that was to take effect August 1, 2026, potentially exposing operators to felony charges, and the CFTC immediately sued Minnesota, seeking a preliminary injunction to block the ban, with the agency arguing the law “turns lawful operators and participants in prediction markets into felons overnight.” A federal court granted that injunction on July 27, 2026 (US v. Minnesota, No. 0:26-cv-02661) — the ban is not in force. Kalshi filed its own suit against the state.

How the Polymarket US Exchange Works

The Polymarket US exchange is fundamentally different from the international platform. Settlement is in US dollars (traditional fiat), and the pUSD stablecoin from the international exchange is not part of the US product. Accounts are funded by debit card, bank transfer (ACH), Apple Pay, PayPal, Venmo or wire transfer (wires have a $5,000 minimum), with USDC deposits on iPhone where available, and all deposits must come from accounts in your own name.

How to Use Polymarket in the US

Americans use Polymarket US, not polymarket.com:

1. Get the app. Download Polymarket from the App Store or Google Play, or use the web version at polymarket.us (still in beta).
2. Sign up and verify. Enter your name, date of birth and address, your SSN, and a phone number confirmed by SMS. Most accounts are verified automatically in seconds.
3. Fund your account by debit card, ACH, Apple Pay, PayPal, Venmo or wire, or with USDC on iPhone where available.
4. Trade. Pick a market and buy Yes or No shares. Which markets you see depends on your state: the app checks your location and can hide categories, most often sports.

Does Polymarket Need Your SSN? (KYC for Polymarket US)

Yes — the Polymarket US exchange asks for your Social Security Number as part of full identity verification (a CFTC requirement). To sign up you provide your full name, date of birth and residential address, plus:

• Social Security Number (SSN)
• A phone number, confirmed by SMS code
• A government-issued photo ID and a live selfie check (conditional — most users are verified automatically in seconds; manual review can take 3–5 business days)

Verification is carried out by Socure, Polymarket’s KYC provider. This is the opposite of the international exchange, which has no KYC — you can sign up with just an email or Google account.

Is There Still a Polymarket US Waitlist?

No — the waitlist was removed in mid-May 2026. For its first six months (December 2025 to May 2026), the Polymarket US exchange was invite-only, and reported waits ranged from 1–2 weeks for the earliest December signups to 6–12 weeks for early-2026 signups. That waitlist has now been dissolved: the app is open to US users without an invite code, live on iOS and Android with the web version in beta.

The remaining gap is liquidity: the US exchange is still significantly lower-liquidity than the international platform. State actions like Minnesota’s ban (enjoined on July 27, 2026, so not in force) could also restrict access in specific states.

What About the International Exchange?

The international Polymarket exchange — the one this site primarily covers — is close-only for US IP addresses (Polymarket’s own geoblock). Polymarket uses a dedicated geoblock API that checks IPs against restricted countries before allowing any order submission.

The restriction is based solely on IP address — there is no KYC or identity verification on the international platform. Some users in restricted regions access international platforms by routing their internet connection through a different geographic location. This is a common practice for accessing global financial and information services.

Polymarket vs Kalshi: The US Prediction Market Battle

Kalshi is Polymarket’s main US competitor. Here’s how they compare:

Both platforms face the same state-level legal challenges and are both subject to the proposed Senate bill to ban sports event contracts.

The Bottom Line for US Residents

1. The international exchange is close-only. Access is restricted by IP address for US users — existing positions can be closed, but no new trades can be opened.
2. The US exchange is now open on iOS, Android and the web. The waitlist was removed in May 2026 — you can sign up directly with full KYC, with the web build still in beta.
3. State laws are a mess. Even with federal approval, your state may be trying to block prediction markets — Minnesota has passed an outright ban, though a federal court has enjoined it, so it is not in force. Check whether your state has taken action.
4. Kalshi is also available as a longer-established, fiat-funded US venue.
5. This is all evolving rapidly. The regulatory landscape is shifting month to month — the CFTC is now suing states to keep prediction markets open. We’ll keep this page updated.
