Polymarket is now two different products wearing one name. The original crypto-native international exchange still runs the way it always has, while a newer, CFTC-regulated US exchange operates under an entirely separate rulebook. Which one you can use, how you fund it, and what protections come with it depend entirely on which side of that split you land on.
Confusing the two is easy and consequential, since they differ on nearly everything that matters. Smart Bet Insider tracks prediction markets and how they actually work. The sections below explain how Polymarket split in two, what each venue offers, the key differences between them, and which one applies to you.
How Polymarket Split in Two
Polymarket launched in 2020 as a single global platform, but a regulatory clash forced the divide. In 2022, the CFTC fined the platform $1.4 million for operating an unregistered derivatives exchange and ordered it to block US users, leaving Americans locked out for nearly four years.
The path back ran through an acquisition. In July 2025, Polymarket bought QCEX, a CFTC-licensed exchange and clearinghouse, for $112 million, and after a federal green light it launched a separate US product in December 2025. The result is two venues operating side by side under different rules.
The Two Venues
Polymarket International
The international exchange at polymarket.com is the original crypto-native platform, running on the Polygon blockchain and settling in USDC stablecoin. Access is through a self-custody wallet with minimal identity verification, and it carries the widest range of markets, from politics and crypto to geopolitics and culture, along with the deepest liquidity. It sits outside CFTC oversight and remains geoblocked for US IP addresses, now in close-only mode for Americans.
Polymarket US
Polymarket US, operated through the acquired QCX entity, is a CFTC-regulated Designated Contract Market. It settles in US dollars with no crypto layer, requires full KYC including a government ID, and is funded by debit card, bank transfer, or wire. In exchange for that regulated structure, its market menu is narrower and shaped by CFTC review, and availability can vary by state.
Two Very Different Rulebooks
The starkest difference is regulation. The international venue is two separate venues removed from US oversight, a decentralized crypto product, while Polymarket US operates within the same federal framework as regulated derivatives exchanges, with customer protections attached to your funds.
Funding and onboarding follow from that split. The international platform uses self-custodial crypto wallets and light verification, whereas Polymarket US uses dollar deposits through regulated intermediaries and mandatory identity checks. The trade-off is real: the international book offers more markets and liquidity, but the US venue can restrict, suspend, or close accounts under its rulebook in ways a self-custody platform cannot.
Which One Applies to You
For US residents, the answer is simple: Polymarket US is the only version you can lawfully use, and the international exchange is closed to you except to wind down existing positions. Trying to reach the international platform through a VPN means using a product that is geoblocked from the US and unregulated for your protection.
For users outside the US, the international exchange remains the fuller product, with broader markets and deeper liquidity, though it comes without the regulatory backstop American users now get. In both cases, knowing which venue you are actually on is the first step, since the rules governing your money are entirely different.
One Name, Two Products
The bottom line is that Polymarket is no longer a single thing, and the venue you use determines your rules, your funding, and your safeguards. The US exchange trades market variety for regulation and customer protection, while the international platform trades those protections for reach and flexibility.
Smart Bet Insider tracks prediction markets and how they work as the landscape keeps shifting. Confirm which venue you are eligible for before depositing, and treat the regulated and unregulated versions as the genuinely different products they are. None of this is legal or financial advice, and anyone trading should use only the platform lawfully available to them and stay within a budget they can afford to lose.

Frequently Asked Questions
What is the difference between Polymarket US and Polymarket International?
Polymarket International is the original crypto-native exchange, running on the Polygon blockchain, settling in USDC, and accessed through a self-custody wallet with minimal verification, but it is unregulated and geoblocked for US users. Polymarket US is a CFTC-regulated exchange that settles in dollars, requires full identity verification, and offers customer protections. They operate under entirely separate rules.
Can US residents use Polymarket?
Yes, but only through Polymarket US, the CFTC-regulated exchange launched in December 2025. The international platform has been geoblocked for US IP addresses since a 2022 CFTC settlement and is now close-only for Americans, meaning they can close existing positions but not open new ones. Polymarket US requires full KYC and dollar funding.
Why is Polymarket International blocked in the US?
In 2022, the CFTC fined Polymarket $1.4 million for operating an unregistered derivatives exchange and required it to block US users. That restriction still applies to the international crypto platform. Polymarket regained US access only by acquiring a licensed exchange and launching a separate, regulated US product.
How do you fund each Polymarket version?
The international exchange is funded with cryptocurrency, primarily USDC held in a self-custody wallet on the Polygon blockchain. Polymarket US is funded with US dollars through a debit card, bank transfer, or wire, with no crypto required. The US version handles money through regulated financial intermediaries.
Which Polymarket has more markets?
The international platform offers a wider range of markets and deeper liquidity, including categories a regulated exchange cannot list. Polymarket US has a narrower menu shaped by CFTC review, focused on areas like sports, economics, and elections, with availability that can vary by state. The trade-off is regulation and protection versus variety.
