Polymarket US: The American Arm of a Global Brand
Polymarket built its name as an offshore, crypto-settled prediction market. Polymarket US is something different: a dollar-only exchange licensed by the Commodity Futures Trading Commission and open to American residents.
The operating company is QCX LLC, which does business as Polymarket US. The CFTC designated QCX as a contract market on July 9, 2025, and its records note that the exchange now operates under the Polymarket US name. Polymarket US’s documentation describes it as both a designated contract market (DCM) and a derivatives clearing organization (DCO), so it lists and clears its own contracts. The iPhone app is published by Blockratize Inc.
The American business has grown quickly. According to Pew Research Center, using data from The Block, Polymarket’s combined global and U.S. volume was about $8.8 billion in May 2026, $14.7 billion in June and $12.9 billion in July. The U.S. exchange’s share of that total climbed from 4% in January to 39% in July. Those are notional figures that count contracts at face value. The company’s claim of “over 30 million users globally” covers the whole brand, not just the U.S. exchange.
When we checked the site on October 29, 2026, the homepage carried a notice that Polymarket US was “undergoing a planned systems upgrade.”
The $25 Polymarket US Deposit Credit
Polymarket US runs a published new-user incentive. Under Campaign A of its Deposit Incentive Program, which began on October 16, 2026, a first deposit of at least $10 made within the program’s seven-day window earns a $25 trading credit. The credit arrives within 24 hours, and the offer is limited to one per person.
| Offer detail | Polymarket US |

| New customer offer | $25 trading credit |
| Qualifying action | First deposit of $10 or more within 7 days |

The credit is not cash. Polymarket US’s help pages say promotional credits cannot be withdrawn, and that cash in an account is used before credits when placing trades.
The referral program works on a username basis. A newcomer who enters an existing member’s username as the referral code, then deposits at least $10, triggers a $25 credit for both people, paid within seven days.
Getting Started: Sign-Up and First Deposit
Registration starts with a Google or Apple ID. Polymarket US then asks for a date of birth, phone number, legal name, home address and Social Security number to complete its identity checks.
