Polymarket processed roughly $7 billion in trading volume in February 2026, and almost none of it came from US-based traders using their real identity. That's not a coincidence. Polymarket has been formally barred from serving US persons since October 2022, when it settled with the Commodity Futures Trading Commission for $1.4 million over operating an unregistered event contract exchange. The platform never rescinded that restriction — it just built better tools to enforce it.
That leaves a strange gap in the market. Polymarket is arguably the most liquid, most accurate prediction market in the world, with Brier scores around 0.09 and open interest near $400 million, yet the country most obsessed with its election odds and Fed rate calls can't legally trade there. Meanwhile Kalshi, a CFTC-regulated exchange, operates openly in 40+ states and pulled in roughly $9.8 billion in the same February 2026 window — more than Polymarket, largely because it's the only major platform Americans can use without a workaround.
This article breaks down exactly where Polymarket is legal, where it's gray-market accessible, why the US restriction exists, and what Polymarket's $112 million acquisition of QCEX means for a possible US relaunch in 2026 or 2027.
Is Polymarket Legal in the United States Right Now
No. Polymarket does not permit US persons — citizens, residents, or anyone accessing from a US IP address — to trade on its primary platform. This isn't a soft suggestion buried in the terms of service. Polymarket enforces it with IP geoblocking, KYC verification checkpoints, and increasingly aggressive VPN detection that flags mismatched location signals.
The restriction traces back to the 2022 CFTC settlement, which required Polymarket to shut down its offering to US persons entirely. For years the platform's enforcement was porous — plenty of Americans traded through VPNs during the 2024 election cycle without much friction. That's changed. Polymarket's compliance stack now cross-references IP geolocation, device fingerprinting, and deposit patterns, and accounts flagged as US-based get frozen pending identity verification that most VPN users can't pass.

Where Polymarket Is Actually Legal
Outside the United States, Polymarket operates in most of the world without a specific license requirement, because it structures itself as a decentralized, non-custodial exchange settled in USDC on Polygon rather than a regulated financial product. Traders in the UK, Canada, most of the EU, Australia, Japan, and the majority of Latin America and Southeast Asia can access the platform, complete KYC, and trade freely.
The exceptions matter. Polymarket blocks access from OFAC-sanctioned jurisdictions — North Korea, Iran, Syria, and similarly restricted countries — as a standard compliance measure any crypto platform follows. Some individual EU member states have also pushed back on specific market categories, particularly election-related contracts, treating them closer to regulated financial derivatives than the platform's own classification. If you're outside the US and considering Polymarket, check the platform's own restricted-jurisdictions list before depositing, since it updates as local regulators weigh in.
| Region | Status | Notes |
|---|---|---|
| United States | Blocked | CFTC settlement bars US persons since 2022 |
| United Kingdom | Legal | Full access with KYC |
| European Union | Mostly legal | Some states restrict election markets |
| Canada | Legal | Full access with KYC |
| Australia | Legal | Full access with KYC |
| OFAC-sanctioned states | Blocked | North Korea, Iran, Syria, others |
Why the US Ban Exists and Why It's Lasted This Long
The CFTC's core argument in 2022 was straightforward: Polymarket's event contracts functioned as unregistered swaps, and the platform never sought a Designated Contract Market (DCM) license before offering them to Americans. Kalshi took the opposite path — it built its entire business as a CFTC-regulated DCM from day one, which is exactly why it can operate legally in 40-plus states today while Polymarket cannot.
The gap between the two platforms isn't about product quality. It's about licensing. Polymarket's peer-to-peer, crypto-settled model was built for speed and global reach, not US regulatory compliance, and retrofitting that structure takes years. That's the entire logic behind Polymarket's acquisition of QCEX, a CFTC-registered derivatives exchange, for $112 million in late 2025. Buying an existing license is faster than building one from scratch, and it's the clearest signal yet that Polymarket wants back into the US market on legitimate terms.
If you want the mechanics of how Polymarket differs from Kalshi on fees, settlement, and regulatory status, our Polymarket vs Kalshi comparison breaks down every category head-to-head.
The QCEX Acquisition and What a US Relaunch Would Look Like
QCEX gives Polymarket a regulatory shell it didn't have before: a functioning CFTC license as a Designated Contract Market. ICE, the parent company of the New York Stock Exchange, has invested up to $2 billion in Polymarket, and the company is reportedly seeking a valuation near $20 billion — numbers that only make sense if US market access is part of the plan.
A relaunch under the QCEX license wouldn't look like the Polymarket US traders remember from 2024. Expect a separate, compliant product — likely USD-settled rather than USDC, with mandatory KYC, position limits, and reporting requirements that mirror Kalshi's current structure. The crypto-native, wallet-based version of Polymarket that international users trade today probably stays international. If you're tracking this migration, our Polymarket review covers the platform's current fee structure and mechanics, which will likely serve as the baseline for whatever the CFTC-regulated version becomes.
Industry and Regulatory Response
CFTC Chairman Selig has publicly supported federal preemption of state-level prediction market restrictions, which would clear a more direct path for platforms like Polymarket and Kalshi to operate nationally under one federal framework instead of fighting state-by-state battles. That stance matters because state regulators haven't been unified. Tennessee ruled in favor of Kalshi's right to operate; Nevada, Massachusetts, Maryland, and Ohio ruled against it, treating event contracts as unlicensed gambling products under state law.
Arizona escalated further, filing criminal charges against Kalshi on March 18, 2026 — a move that signals states aren't waiting for federal clarity before acting. Congress has entered the fight too. The Schiff-Curtis "Prediction Markets Are Gambling Act," introduced March 23, 2026, would reclassify event contracts as gambling products subject to state licensing, which would undercut the CFTC's exclusive jurisdiction claim and complicate any Polymarket US relaunch significantly. Eleven states introduced their own prediction market legislation in 2026, and none of it has landed in the same place.

What This Means for US Traders Right Now
If you're in the US today, Polymarket is not a legal option, and using a VPN to access it violates the platform's terms of service — accounts get frozen, and funds can get stuck in a compliance review that has no guaranteed resolution timeline. That's a real risk, not a theoretical one. Polymarket has tightened enforcement specifically because it needs a clean compliance record while pursuing its CFTC license through QCEX, and every VPN workaround it catches undermines that case.
Your legal alternative right now is Kalshi, which offers similar sports and political event contracts under full CFTC regulation in 40-plus states. Robinhood's prediction hub runs on Kalshi's infrastructure too, so if you already have a brokerage account there, you have legal access without opening a new platform. Our best prediction market apps guide ranks every legally accessible option for US traders, and apps like Polymarket covers alternatives if you specifically want Polymarket's market selection and pricing style.
One more thing worth knowing before you trade anywhere: profits are taxable regardless of which platform you use or whether it's technically legal in your state. Kalshi issues a 1099-MISC; Polymarket issues nothing, which doesn't mean the income is exempt. The IRS has issued zero formal guidance on how to classify prediction market winnings, and our prediction market tax guide walks through the three competing treatments — ordinary income, gambling, and the more aggressive Section 1256 approach — plus the 90% gambling loss cap starting tax year 2026 under OBBBA.

What Happens Next
Watch the CFTC's handling of the QCEX license application closely — approval would be the single clearest signal that a compliant US version of Polymarket is coming, likely with a separate product structure and mandatory KYC that mirrors Kalshi's current setup. Congressional movement on the Schiff-Curtis bill is the other variable that matters. If it advances, it reclassifies event contracts as gambling products under state jurisdiction, which would complicate federal preemption arguments and could delay any Polymarket US relaunch by years rather than months.
State-level litigation is also unresolved. With Tennessee siding with Kalshi and four other states ruling against it, expect appeals and possibly a circuit split that pushes the question toward the Supreme Court or forces Congress to act decisively one way or the other. Until one of these threads resolves, Polymarket's US legal status stays exactly where it is now: blocked, with a plausible but unconfirmed path back through QCEX.
Frequently Asked Questions
Is Polymarket legal in the US in 2026?
No. Polymarket has barred US persons from its platform since a 2022 CFTC settlement, and it enforces that ban with IP geoblocking, KYC checks, and VPN detection. See our full breakdown of US prediction market legality for the broader regulatory context.
Can I use a VPN to access Polymarket from the US?
You can attempt it, but it violates Polymarket's terms of service and risks account freezes with no guaranteed path to recovering funds. Polymarket has tightened detection specifically because it's pursuing a CFTC license through its QCEX acquisition, and it needs a clean compliance record to get there.
What countries can legally use Polymarket?
Most countries outside the US, including the UK, Canada, Australia, and the majority of the EU, allow full access with standard KYC verification. OFAC-sanctioned states like North Korea, Iran, and Syria are blocked, along with any jurisdiction under active sanctions.
Will Polymarket become legal in the US?
Possibly. Polymarket's $112 million acquisition of QCEX, a CFTC-registered exchange, is a direct move toward relaunching a compliant US product, and ICE's up to $2 billion investment suggests real confidence in that path. No confirmed launch date exists yet, and pending legislation like the Schiff-Curtis bill could complicate the timeline.
What's the legal alternative to Polymarket for US traders?
Kalshi is the primary legal option, operating as a CFTC-regulated exchange in 40-plus states with similar sports and political contracts. Robinhood's prediction hub also runs on Kalshi's infrastructure. Compare both directly in our Polymarket vs Kalshi guide.
Does the CFTC settlement mean Polymarket is untrustworthy?
No — the settlement was about unregistered licensing in the US, not platform integrity or solvency. Polymarket's Brier scores around 0.09 indicate strong market accuracy, and our Polymarket legitimacy review covers the evidence in detail.
Do I owe taxes on Polymarket winnings if it's not legal in my state?
Yes. Tax obligations are separate from state-level legality, and the IRS expects reported income regardless of which platform generated it or whether that platform operated legally in your jurisdiction. Read our prediction market tax guide for how to report it correctly.
How is Kalshi different from Polymarket legally?
Kalshi built its business as a CFTC-regulated Designated Contract Market from the start, which is why it operates legally across most US states today. Polymarket operated without that license until its 2022 settlement, and it's now trying to acquire equivalent status through the QCEX purchase.
