Yes — as of June 2026, Polymarket is legal for US residents, but only through a specific product: Polymarket US, operated by QCX LLC, a CFTC-regulated Designated Contract Market that launched in December 2025. That regulated venue is the one Americans can lawfully use. The separate global, crypto-native Polymarket that most people know from the 2024 election remains geoblocked for US users. The distinction is the whole answer, and getting it wrong is how people end up confused about whether Polymarket is "banned" or not.

This guide walks through exactly how Polymarket became legal again, how the US version differs from the global one, the state-level friction that's still playing out in 2026, and what all of it means for you as a trader. Every legal claim below is sourced to a primary document — the CFTC, official company announcements, or court filings — because this is a question where secondhand summaries get it wrong constantly.

This is not legal advice. Regulation of prediction markets is changing fast and varies by state. Verify your own jurisdiction before funding any account, and consult a qualified attorney for advice specific to your situation.

The Short Answer

• Federally legal. Polymarket US operates as QCX LLC d/b/a Polymarket US, a CFTC-regulated Designated Contract Market (DCM). The CFTC issued an amended order of designation, signed November 24, 2025, and the US platform launched in December 2025.
• It got here by acquisition. After exiting the US in 2022, Polymarket acquired QCEX — a CFTC-licensed exchange and clearinghouse — for $112 million in July 2025, inheriting the regulatory credentials it needed to re-enter.
• Two separate venues. Polymarket US is the regulated, US-facing platform. The global Polymarket (on-chain, stablecoin-settled) is a distinct, crypto-native venue that stays geoblocked for US IP addresses.
• State friction is real. Even with federal approval, several state regulators have challenged prediction markets in 2026 — and the CFTC has sued several states in response, arguing federal law preempts them.
• For context, Kalshi has been a CFTC-regulated DCM since November 2020; the comparison is in Polymarket vs Kalshi.

If you're a US resident, the practical version is: you can legally trade on Polymarket US, subject to identity verification and your state's availability. New to the platform itself? Start with what Polymarket is.

A Short History: Ban → Acquisition → Relaunch

Understanding today's status requires three steps.

2022 — the exit. Polymarket settled with the CFTC and agreed to block US users. For roughly three years, the platform was unavailable to Americans, operating as a global, on-chain venue that geoblocked US IP addresses as a condition of that settlement.

July 2025 — the acquisition. Polymarket announced on July 21, 2025 that it had acquired QCEX — a CFTC-licensed derivatives exchange (QCX, LLC) and clearinghouse (QC Clearing LLC) — for $112 million. The strategic logic, per the company's own announcement, was that QCEX's existing CFTC registration would "fast track" Polymarket's return to the US without spending years navigating the approval process from scratch.

December 2025 — the relaunch. Following an amended order of designation from the CFTC, signed November 24, 2025, Polymarket US launched as a regulated DCM in December 2025. (Public sources differ on the exact launch day, so we cite the month rather than a specific date.) This is the regulated venue US residents can use today.

How Polymarket US Differs From Global Polymarket

This is where most confusion lives. There are two Polymarkets, and only one is for US users.

Polymarket US (QCX LLC) is the CFTC-regulated DCM. As a federally regulated derivatives exchange, it operates under the same broad framework as Kalshi — meaning identity verification is part of the deal. Reporting on the US launch indicates Polymarket US requires full KYC, including a government-issued ID, Social Security number, and proof of US residency, consistent with the federal anti-money-laundering rules that apply to a regulated exchange. This is the venue you should expect to use as an American.

Global Polymarket is the on-chain, crypto-native platform: it settles in a USD-pegged stablecoin on Polygon, lists thousands of global event contracts, and resolves through the UMA decentralized oracle. This is the version that went viral during the 2024 US election — and it remains geoblocked for US IP addresses as a condition of the 2022 settlement. US residents are not meant to access it.

The mechanics of how a regulated, USD-settled prediction market works versus an on-chain one are the same mechanics that distinguish Kalshi from global Polymarket — we break them down side by side in Polymarket vs Kalshi.

State-Level Friction (As of June 2026)

Federal approval settled the federal question. It did not end the fight at the state level, and this is the part of the answer that's still moving.

Even after the CFTC designation, several state regulators moved against prediction-market platforms — arguing the event contracts amount to unlicensed gambling under state law. Reported state actions in 2026 include cease-and-desist letters to Polymarket from regulators in Tennessee (the first state-level cease-and-desist, reported weeks after the US relaunch) and Illinois, among others, and a wave of similar challenges across multiple states. Coverage as of mid-2026 indicates that officials in roughly a dozen states have issued cease-and-desist orders or filed suit against prediction-market operators, with at least one state pursuing an outright ban.

The federal government pushed back hard. On April 2, 2026, the CFTC sued Connecticut, Arizona, and Illinois — a move the agency itself described as reaffirming "its exclusive jurisdiction over prediction markets" — challenging those states' attempts to regulate CFTC-registered prediction-market operators, including the cease-and-desist letters issued over the prior year. The CFTC's position is that event contracts on a federally designated exchange fall under the Commodity Exchange Act, and that federal law preempts state gambling rules. Weeks later it extended the campaign with a similar suit against Wisconsin.

The bottom line for 2026: there's an active, unresolved conflict between federal preemption (the CFTC's stance) and state gambling authority. Several states have challenged availability, the courts are now involved, and the picture can change. Check your specific state before you fund an account — the federally legal answer doesn't guarantee the platform is available, or uncontested, where you live.

What This Means for You as a Trader

Strip away the legal noise and here's the practical reality for a US resident in June 2026:

• You can legally trade on Polymarket US. It's a CFTC-regulated exchange, so trading prediction-market contracts on it is lawful at the federal level.
• Expect to verify your identity. As a regulated venue, Polymarket US applies KYC — government ID, SSN, proof of residency. The anonymous, wallet-only experience belongs to the global platform you can't use.
• Your state matters. Availability and the legal climate vary by state, and several states are actively contesting it. Confirm your jurisdiction first.
• Don't try to route around the geoblock. The global Polymarket is geoblocked for US users by design; using a VPN to access it puts you outside the regulated venue meant for you.

Whichever regulated venue you choose, the trade itself settles on that platform's own infrastructure. If you want to compare Polymarket against the other major CFTC-regulated venue before deciding where to fund, read Polymarket vs Kalshi, and if you're brand new to the concept, what Polymarket is covers the basics.

Frequently Asked Questions

Is Polymarket legal in the US in 2026?

Yes. As of June 2026, US residents can legally trade on Polymarket US, operated by QCX LLC — a CFTC-regulated Designated Contract Market that launched in December 2025 following the CFTC's amended order of designation signed November 24, 2025. The separate global Polymarket platform remains geoblocked for US users. Availability and the legal climate vary by state, so check your jurisdiction. This is not legal advice.

Why was Polymarket banned in the US?

Polymarket settled with the CFTC in 2022 and agreed to block US users, operating as a global, on-chain venue afterward. It re-entered the US legally by acquiring QCEX — a CFTC-licensed exchange and clearinghouse — for $112 million in July 2025, then launching the regulated Polymarket US in December 2025.

What is the difference between Polymarket US and global Polymarket?

Polymarket US (QCX LLC) is the CFTC-regulated, US-facing exchange with identity verification (KYC). Global Polymarket is the on-chain, crypto-native platform that settles in a USD-pegged stablecoin on Polygon and resolves via the UMA oracle — and it stays geoblocked for US IP addresses. US residents should use Polymarket US, not the global venue.

Do I need to verify my identity to use Polymarket US?

Yes. As a federally regulated exchange, Polymarket US applies KYC. Reporting on the US launch indicates it requires a government-issued ID, Social Security number, and proof of US residency, consistent with the anti-money-laundering rules that apply to a regulated derivatives venue. The anonymous, wallet-only flow belongs to the global platform US users can't access.

Is Polymarket legal in every US state?

No. Federal CFTC approval makes Polymarket US legal at the federal level, but availability varies by state, and several state regulators have challenged prediction markets in 2026 — issuing cease-and-desist letters and lawsuits. The CFTC sued Connecticut, Arizona, and Illinois on April 2, 2026 (and Wisconsin weeks later), arguing federal law preempts the states. The conflict is unresolved, so verify your specific state before funding an account.

Is Polymarket the same as Kalshi legally?

Both are CFTC-regulated Designated Contract Markets in 2026. Kalshi has held DCM status since November 2020; Polymarket re-entered the US as a CFTC-regulated DCM (via QCX LLC) in December 2025. Both face state-level challenges, and the CFTC's April 2026 suit defends both. The practical differences — funding, fees, markets — are covered in Polymarket vs Kalshi.

Is it safe to use a VPN to access global Polymarket from the US?

The global Polymarket is geoblocked for US users by design, as a condition of the 2022 CFTC settlement. Using a VPN to bypass that puts you outside the regulated venue intended for US residents. The lawful path for Americans is Polymarket US. This is not legal advice — consult an attorney about your specific situation.
