On polymarket.com you create an account with Google, with your email and a 6-digit code, or by connecting a crypto wallet such as MetaMask, Rabby or Phantom; there is no ID check at sign-up, the Terms require you to be 18 or older, and the account gets a non-custodial wallet tied to the login you used. US residents can't deposit or trade on polymarket.com and instead sign up in the separate Polymarket US app with Google or Apple ID, followed by an identity check based on name, date of birth and address.
This guide goes through each polymarket.com sign-up method step by step, what the sign-up creates behind the scenes, the settings you can change afterwards, how to export your key, keep the account safe and delete it, and then the Polymarket US app's sign-up and identity check. Facts come from Polymarket's help center, developer docs and Terms, the Polymarket US docs and the official store listings; where they disagree or say nothing, we say so. Nothing here is an invitation to open an account.
US residents can't deposit or trade on polymarket.com; they use the separate Polymarket US app. Polymarket also blocks or limits trading in many other countries, and governments add blocks of their own. Check where Polymarket and Kalshi are available before you move any money.
Polymarket's Terms of Use prohibit using a VPN or similar tool to get around these restrictions, and doing so can also break local law. PolyKal doesn't help anyone get around them.
Polymarket's help center lists three ways to sign up. Each one creates an account tied to that particular login, so decide which one you'll keep using before you start. The button names below are the help center's; labels on screen may differ slightly.
On polymarket.com, click Sign Up, choose “Continue with Google”, then pick the Google account to connect and finish the prompts. From then on you log in with that same Google account.
Read every request your wallet shows before you confirm it. The help center describes the sign-up requests as message signatures, and none of its steps asks for your wallet's recovery phrase or private key: Polymarket says it will never ask for your private key.
Whichever method you pick becomes the thing you have to protect: your Google account, your email inbox, or your wallet and its recovery phrase. A different Google account, email address or wallet opens a different, empty account, not yours.
Your settings are at polymarket.com/settings, which on September 24, 2026 had six tabs: Profile, Account, Trading, Notifications, Relayer API keys and Builders.
The Profile tab has a profile picture (Upload), Username, Email (with an “Add email” option), Address and Bio (up to 200 characters), with Save changes and Cancel buttons. We couldn't confirm whether new users are asked to pick a username right after their first sign-in, or which of these fields other users can see, so don't put anything there you wouldn't want to be public.
Account deletion starts on the Account tab (see below). We couldn't see what the Account, Trading and Notifications tabs contain without signing in, and the help center doesn't document them, so we don't describe them. Relayer API keys are for developers using Polymarket's API for gasless operations; the docs don't make them part of a normal sign-up.
We found no Polymarket help center article on this. What its docs do say is that each account's wallet is tied to the login that created it, so on a new phone or computer, sign in with exactly the same method: the same Google account, the same email address with a new 6-digit code, or the same wallet address connected from that device. Any other login creates a new, empty account instead of opening yours.
Type polymarket.com into the browser yourself rather than following a link. If you see a “Network Error”, the help center suggests turning off VPNs, proxies and privacy extensions, checking that the device clock is correct, clearing the site's data, refreshing the page, and logging out and back in.
Because the account is non-custodial, the help center says you can export your private key at any time. Its steps are written for accounts created with email and go through Magic, a third-party wallet service:
The article dates from January 2026, before Deposit Wallets arrived on May 4, 2026, and it doesn't say whether the same steps work for Google sign-ups or newer accounts; if they don't work for you, ask Polymarket support through the channels below. If you signed up with a wallet such as MetaMask, Rabby or Phantom, the key is held in that wallet, not by Polymarket, so these steps don't apply.
Anyone who has the key controls the funds. The help center says: “DO NOT share your private key with other parties, platforms, or people. We will never ask for your private key.” Don't paste it into any website, bot, form or chat message.
Other incidents have been reported too, including a flaw at a third-party login provider that let attackers drain some email-login accounts in December 2025, and a malicious third-party script on Polymarket's own site in June 2026, after which Polymarket said it would refund affected users in full. The dated list is in our Polymarket app guide.
The help center's steps (updated June 25, 2026):
Afterwards, your profile and personal data are deleted in line with Polymarket's Privacy Policy, although some data may be kept where the law requires it, and your past transactions remain visible on the blockchain. For help, email [email protected] or use the chat on the site. These steps are for polymarket.com; a Polymarket US account is separate, so ask its support.
Polymarket US is the separate product for US residents, operated by QCX LLC d/b/a Polymarket US, a CFTC-regulated designated contract market. Its accounts aren't connected to polymarket.com, so it needs its own sign-up even if you already have a website account. According to news reports, the waitlist and invite codes were removed on May 12, 2026. Install the app only from the official App Store or Google Play listing; our Polymarket app guide shows how to check you have the right one.
The Polymarket US docs describe five steps; labels in the app may differ slightly:
Polymarket US says verification is required under “federal identity and anti-money-laundering (AML) rules”. Its retail sign-up page lists name, date of birth and residential address, plus an ID document and selfie for some users, and doesn't mention a Social Security number (SSN). However, its documentation for partner apps lists SSN, email, phone number and IP address among the verification data and names Socure as the verification provider. Whether the app itself asks for an SSN, and if so the full number or only the last four digits, isn't confirmed.
Enter your details exactly as they appear on your ID: information that doesn't match or is missing is the first reason Polymarket US gives for putting an account under review, and deposits later have to come from accounts in your own name.
Most users are verified automatically, according to the docs. If your account goes to manual review, the retail docs say it can take up to 3–5 business days, while the partner documentation gives 1–2 business days for its own flow. Business days exclude weekends and public holidays, so a 5-business-day review that starts on a Thursday can run until the following Thursday. You're told in the app and by email when the account becomes active.
Polymarket US lists three common reasons for a review: information that doesn't match or is missing, similar information found on another account, and additional identity checks for KYC or AML compliance. It says the review concludes automatically.
We found no official page on appealing or retrying a failed check. In the verification flow Polymarket US documents for partner apps, a rejected applicant “cannot trade on the platform” and no account is created. If you're stuck, contact support through the in-app chat under account settings or at [email protected], and never share a verification code, even with support.
Both store listings rate the app 18+, and the App Store listing adds: “18+ only. Restrictions and eligibility requirements apply.” Some news reports say you must be 21 in some states or generally; we found no official state-by-state age list, so go by what the app tells you.
The App Store listing describes the app as CFTC regulated “in all 50 states” but says trading is “currently unavailable in NV” (Nevada). News reports name several other states where new accounts are restricted, and they disagree with one another; we found no official list. About 20 states are reported to be in court disputes with Polymarket, so this can change: see where Polymarket and Kalshi are available.
After verification, deposits are by debit card, bank transfer (ACH) or wire from an account in your own name (wires have a $1,000 minimum), and withdrawals must go back to the same payment method. Details: deposits and withdrawals.
The US app's security rests on your Google account or Apple ID: Polymarket US tells users to keep them secure, to sign in only through the official app and to avoid fake Google or Apple login screens. In July 2026, about 500 Polymarket US accounts were compromised through a registration flaw that let attackers in with stolen personal data, according to a Wall Street Journal report cited by The Block.
| At a glance | polymarket.com | Polymarket US app |
|---|---|---|
| Who can use it | People outside the US, in countries Polymarket doesn't block or limit | US residents, except where the app is unavailable (Nevada, per the App Store listing) |
| Sign-in | Google, email with a 6-digit code, or a crypto wallet | Google or Apple ID |
| Identity check | None in the sign-up flow; the Terms allow requests for more information | Required: name, date of birth and address; sometimes a photo ID and a selfie |
| Minimum age | 18 (Terms of Use) | 18+ on both store listings; some reports say 21 in some states |
| Money in and out | Crypto from many networks, converted to pUSD on Polygon; card or bank payments through a third-party on-ramp | US dollars by debit card, bank transfer (ACH) or wire, from an account in your own name |
| What you hold | pUSD in a non-custodial wallet tied to your login | A US dollar cash balance; withdrawals go back to the payment method you deposited with |
The rest of the process is covered in separate guides: which app is official and how to spot fakes in the Polymarket app guide, moving money in deposits and withdrawals, placing an order in how to buy on Polymarket, and the whole process in the Polymarket tutorial.
On polymarket.com, click Sign Up and choose Google, email (you then enter a 6-digit code sent to your inbox) or a crypto wallet such as MetaMask, Rabby or Phantom. The account gets a non-custodial wallet tied to that login, so always sign in the same way. US residents can't deposit or trade on polymarket.com and sign up in the separate Polymarket US app instead.
Not on polymarket.com: the help center's sign-up steps have no ID check, although the Terms let Polymarket ask for more information, for example to confirm you aren't a Restricted Person. The Polymarket US app does require verification: name, date of birth and address, and for some users a government-issued ID and a selfie.
18. polymarket.com's Terms say the site is intended only for users 18 or older, and both US app store listings are rated 18+. Some news reports say the US app requires 21 in some states; we found no official list.
Not on polymarket.com: US residents can't deposit or trade there. They can sign up in the Polymarket US app, a separate CFTC-regulated product with its own account, identity check and US dollar payments. The App Store listing says trading is unavailable in Nevada, and news reports name other restricted states.
One possible cause is signing in with a different method from the one you signed up with. Each account's wallet is tied to its login, so another email address, Google account or wallet opens a separate, empty account; log out and sign in exactly as you did at sign-up. A polymarket.com account also doesn't appear in the US app, because the two aren't connected. If neither applies, email [email protected] for help.
Yes, polymarket.com is. The help center says “Polymarket is non-custodial, so you're in control of your funds”, and the Terms say Polymarket can't access your private key or the crypto in your wallet. That also means support can't restore lost login details or keys.
Sign in to polymarket.com, follow the link in the help article How Do I Export My Key? to Magic's key-reveal page, sign in there, export the key, store it where no one else can access it, and log out. The article covers email sign-ups; wallet sign-ups hold their key in their own wallet. Polymarket says it will never ask for your private key.
We found no 2FA setting or help article for polymarket.com. Your account is as secure as the email inbox, Google account or wallet you sign in with, so protect that; the US app relies on your Google account or Apple ID.
Most users are verified automatically. If a manual review is needed, the Polymarket US docs say it can take up to 3–5 business days, and you're notified in the app and by email when the account becomes active.
The retail sign-up page lists only name, date of birth and address, plus an ID and selfie for some users. Polymarket US's documentation for partner apps includes the SSN; whether the app itself asks for it, and if so all nine digits or only the last four, isn't confirmed.
Close all positions, withdraw all funds, then start the deletion at polymarket.com/settings?tab=account; the system blocks deletion while any positions or tokens remain. Personal data is deleted under the Privacy Policy except where the law requires keeping it, and your transaction history stays visible on the blockchain.
