Polymarket US review
CFTC-regulated US event-contract exchange run by QCX LLC, USD only
In United States: QCX LLC publishes no list of eligible or excluded states. A Nevada court granted a preliminary injunction against QCX LLC d/b/a Polymarket US on 29 May 2026 (Nevada Gaming Control Board). Missouri's Attorney General has sent a cease-and-desist over sports contracts, and New York has announced a lawsuit; neither state is marked closed because the operator has not said it geoblocks them.
Our verdict
The US exchange that carries the Polymarket name — and a different company from polymarket.com. QCX LLC has been a CFTC-designated contract market since 9 July 2025 and clears through its own registered clearing house, so this is a dollar account with identity checks before the first deposit, not a crypto wallet.
The fee is a published formula that peaks at $1.74 per 100 contracts at 50¢, with a maker rebate. Two things to know before signing up: the operator publishes no list of eligible states, and a Nevada court enjoined it there on 29 May 2026. Scored provisionally from its documents on four of nine criteria — we have not traded on it.

Where is Polymarket US available?
Individual participants must be natural persons "at least 18 years of age, having attained the age of majority in your state" (Individual Participant and Clearing Member Agreement §II.1). The agreement also excludes residents of any jurisdiction where trading "is prohibited under Applicable Law or by PMUS policy", including OFAC-sanctioned and FATF-listed jurisdictions.
None of the operator documents we read (docs, participant agreement, rulebook, website terms) publishes a list of eligible or excluded US states. The iOS and Google Play listings claim "CFTC regulated in the United States — in all 50 states", yet a Nevada court has enjoined QCX LLC d/b/a Polymarket US in that state.
What fees does Polymarket US charge?
Taker fees follow a formula rather than a flat percentage: "Fee = Θ × C × p × (1 - p)", with a taker theta of 0.0695. The fee peaks at $1.74 per 100 contracts at a $0.50 price, which is about 3.5% of the $50 trade value, and falls toward zero near $0.01 or $0.99. Makers currently receive a rebate with a theta of -0.0125 (up to $0.31 per 100 contracts).
Takers who traded $250k to $999,999 the previous month get 10% back, $1M to $9.99M gets 25%, and $10M+ gets 50%. Combos (parlays) carry a higher taker curve that adds a 0.06 × (1-p)^4 term. The schedule reads "Effective exchange-wide from 10 AM ET, Thursday October 1, 2026" (docs.polymarket.us/fees, read 5 Oct 2026). Changes are pending.
From 7 Oct 2026 combo trades lose the maker rebate and the Table Tennis taker coefficient becomes 0.10, according to the same page.
CFTC 40.6(a) filings dated 2 Oct 2026 attach a fee schedule marked "Effective October 19, 2026": the flat maker rebate becomes tiered, at Θ −0.0035, −0.0070 or −0.0104 for makers with at least $10M, $50M or $200M of prior-month maker volume and none below $10M, and the taker rebate becomes 3%, 5%, 10%, 15% or 30% of fees paid from $250k, $1M, $10M, $25M and $50M of prior-month taker volume.
Withdrawals are described as free ("Withdraw your cash balance securely and for free"). No deposit fee is stated anywhere in the docs.
These are document checks, not a funded-account test. Access may depend on residence, physical location, account approval and the contract category. Check the operator’s current terms before depositing.

Polymarket US guides
- Is there a Polymarket waitlist? How to get access to Polymarket US
Polymarket.com is closed to US residents, so Americans use Polymarket US, a separate CFTC-regulated app. Its current sign-up has no waitlist step: you register, verify your identity and can trade once approved. What the sign-up asks for, the one place invite codes still come up, and who can join.
- How to withdraw from Polymarket and Polymarket US
On Polymarket.com you withdraw your balance as crypto to a wallet on the chain you choose, with no Polymarket fee. On Polymarket US you withdraw dollars to the card, bank or wallet you deposited from, usually within 3–4 business days. Step by step, with the rules that hold money back.
- Polymarket taxes: what Polymarket and Polymarket US report, and what the IRS says
Polymarket US collects your Social Security number and has you consent to receive IRS Form 1099-B electronically. Polymarket’s international site issues no tax forms that we could find, and puts tax entirely on you. The IRS has not said how event-contract gains are taxed. What is known, and what isn’t.
- Polymarket fees: what you pay on Polymarket and Polymarket US
Polymarket charges a fee only when you take liquidity, never when your order rests on the book, and the rate depends on the market’s category. Polymarket US, the separate app for US residents, has its own fee formula and volume tiers. Both, with worked examples.
- The Polymarket API: market data, trading and Polymarket US
Polymarket’s market data is free to read with no API key; trading through its API needs credentials derived from your wallet and is blocked from restricted countries, including the US. US traders use a separate Polymarket US API. What each part does and how to start.
- Is Polymarket legal in the US? Polymarket vs Polymarket US
Two exchanges carry the Polymarket name. Polymarket US is a CFTC-designated exchange open to US residents; polymarket.com, the international one, blocks them. Here is what each is, and where states have pushed back.
- Limit orders on Kalshi and Polymarket: how to use them and why they cost less
A limit order sets the price you are willing to pay or accept and waits on the order book until someone trades with it. It can save you the spread and, on Polymarket, the taker fee, at the risk of never filling. The order types each exchange offers, how fees treat them, and what happens to unfilled orders.
- How to short on Polymarket, and how to sell before a market resolves
There is no short button on Polymarket because there doesn’t need to be one: betting against an outcome means buying its NO shares, or selling YES on Polymarket US. You can also sell any position before the result at the current bid. How each works, what it costs, and how much you can lose.
