Is Polymarket Legal in the US? Here's the Truth

The answer to whether Polymarket is legal in the US has changed significantly in late 2025 — and the short answer now is yes, with caveats. After three years of blocking US users following a 2022 CFTC enforcement action, Polymarket received regulatory approval to relaunch in the United States in November 2025. The platform acquired QCEX, a CFTC-licensed derivatives exchange, for $112 million, received an Amended Order of Designation from the CFTC, and began onboarding US users again in December 2025. This is a major development that changes the legal picture entirely for American participants.

That said, the regulatory history here matters, and the situation is still evolving. Polymarket spent years blocked from the US market, and its return comes with ongoing legal scrutiny, state-level challenges that mirror what its competitor Kalshi is facing, and a new operational structure that's different from how the platform worked before. Our full Polymarket review covers the platform in depth, but this guide is specifically for anyone trying to understand the legal landscape — where things stood, where they are now, and what to watch going forward.

If you were about to reach for a VPN to access Polymarket, you can put that away. The relevant question for US users in 2026 is no longer whether you can participate, but how the new regulatory structure works and what state-level complications may affect you depending on where you live.

What Happened in 2022: The CFTC Settlement

To understand where things stand today, you need to understand what happened three years ago. In January 2022, the CFTC settled an enforcement action against Polymarket — then operating as Blockratize Inc. — for running an unregistered facility for event-based binary options contracts. The core violation was straightforward: Polymarket had been offering prediction market contracts to US users since approximately 2020 without being registered as either a Designated Contract Market (DCM) or a Swap Execution Facility (SEF), as required under the Commodity Exchange Act.

The settlement required Polymarket to pay a $1.4 million civil monetary penalty, wind down non-compliant markets, and block US persons from participating going forward. The fine was reduced from a higher potential amount due to Polymarket's substantial cooperation with the investigation. Importantly, the settlement didn't shut Polymarket down globally — it simply drew a hard line around the American market and required the company to restructure its compliance posture.

From early 2022 through late 2025, Polymarket operated as a global platform explicitly unavailable to US users. The platform implemented IP-based geo-blocking, and its terms of service prohibited US participation. During this period, Kalshi was the primary CFTC-regulated option for US-based prediction market participants.

Polymarket Returns to the US: What Changed in 2025

The regulatory environment shifted significantly under the new administration in 2025. In July 2025, the DOJ and CFTC formally ended their investigations into Polymarket without bringing additional charges. That same month, Polymarket announced the acquisition of QCEX, a CFTC-licensed derivatives exchange and clearinghouse, for $112 million. The acquisition gave Polymarket the regulatory infrastructure it needed to operate legally in the United States.

In November 2025, the CFTC issued an Amended Order of Designation for Polymarket through QCEX, permitting it to operate as an intermediated trading platform subject to the requirements applicable to federally regulated US exchanges. Polymarket began onboarding US users through this new structure in December 2025. As of 2026, US residents can legally create accounts and participate in Polymarket's prediction markets — a complete reversal from the situation that existed for the previous three years.

This new structure differs from the old one. Polymarket now operates through a CFTC-licensed intermediary, must comply with reporting, surveillance, and customer protection requirements, and allows trading through Futures Commission Merchants. It's a more regulated model than the original decentralized setup, though the on-chain settlement mechanics and USDC-based trading remain core to the platform.

State-Level Complications: Not Fully Resolved

Federal CFTC approval doesn't automatically resolve every legal question for US participants. Just as Kalshi has faced state-level challenges over its sports event contracts, Polymarket has encountered similar resistance from state gaming regulators. Nevada has specifically banned Polymarket from offering sports, entertainment, and election contracts to its residents, alongside Kalshi, Robinhood, and Crypto.com. Other states including Ohio, Michigan, Arizona, Maryland, and Massachusetts have also moved against prediction market platforms on gaming law grounds.

The core dispute is whether CFTC oversight under the Commodity Exchange Act preempts state gambling laws — a question that federal courts have answered inconsistently across different jurisdictions. New Jersey and Tennessee have sided with prediction market platforms; Nevada, Ohio, Maryland, and several others have sided with state regulators. This litigation is actively ongoing as of April 2026, with the 9th Circuit scheduled to hear the Nevada case and the 4th Circuit set to hear Maryland's case later in 2026.

The practical implication for US users: your ability to participate in certain Polymarket contracts — particularly sports and entertainment markets — may depend on what state you're in. Political and economic markets are generally less contested. If you're in Nevada specifically, access to sports-related markets has been blocked by court order. If you're in the other states where litigation is ongoing, the situation is fluid. Users in states without active enforcement actions can generally participate fully.

Polymarket vs. Kalshi for US Users in 2026

With Polymarket back in the US market, American participants now have a genuine choice between two platforms rather than a single regulated option. Kalshi holds a DCM license it has had since 2020 and operates entirely in US dollars with standard bank deposit options. Polymarket operates through its QCEX structure with USDC on the Polygon blockchain, which still requires crypto wallet familiarity. Kalshi has stronger coverage of US economic and political markets; Polymarket has deeper global liquidity on major events and a broader international market catalog.

Both platforms face the same state-level headwinds on sports contracts, and both are navigating the ongoing federal-versus-state legal battle that will ultimately be resolved by appellate courts over the next year or two. If you prefer fiat deposits and a fully US-centric experience, Kalshi remains the more accessible entry point. If you're comfortable with crypto and want access to Polymarket's global liquidity and market depth, the platform is now a legal option for most US residents.

Is Polymarket Legal in the US? The 2026 Verdict

Yes — as of late 2025, Polymarket is legally accessible to US residents through its QCEX subsidiary, which holds a CFTC Amended Order of Designation. This represents a complete reversal from the 2022 enforcement action that blocked US participation for three years. The platform now operates under federal regulatory oversight, with reporting and compliance requirements that apply to regulated US exchanges.

The remaining complications are state-level, not federal. Nevada has court-ordered restrictions on sports and entertainment contracts. A dozen other states have active litigation against prediction market platforms broadly. These restrictions are sport/entertainment-specific in most cases and don't affect access to political, economic, or other non-sports markets. If you're a US resident outside of Nevada and want to participate in Polymarket's prediction markets, the legal path is now clear at the federal level — but worth monitoring at the state level depending on where you live and what markets you're interested in.
