Polymarket.com runs on crypto: you deposit from a supported network, the funds are converted to pUSD on Polygon, and a withdrawal sends them out as crypto to an address you choose. Polymarket itself charges no deposit or withdrawal fee, but network, bridge and card on-ramp costs can apply, and the US app is a separate product funded by bank transfer, debit card or wire.
This guide covers both directions for both Polymarket products: the international site polymarket.com, which runs on the Polygon blockchain, and the Polymarket US app, a CFTC-regulated exchange with separate accounts. Every step and number below comes from Polymarket's own documentation and help center, and where those sources disagree we say so. It explains how things work; it is not 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.
Since an exchange upgrade on April 28, 2026, balances on polymarket.com are held in pUSD (Polymarket USD), a token on Polygon backed 1:1 by USDC. When you deposit USDC, it is wrapped into pUSD with no Polymarket fee; other tokens are swapped first and then wrapped. Winning shares redeem for $1.00 pUSD each.
pUSD isn't listed on outside exchanges, and Polymarket says there are no current plans to list it. That matters when you withdraw: see withdrawing to an exchange below.
The Help Center describes the same short flow for every crypto deposit:
Supported networks include Ethereum, Polygon, Arbitrum, Base, Optimism, BNB Smart Chain, Solana, Bitcoin and Tron, among others, with stablecoins such as USDC and USDT plus many other tokens on the main networks. The list changes, and Polymarket's own pages don't fully agree, so treat the deposit screen as the current list. Polymarket's advice is to test with a small amount before sending a large one.
Minimums are small, a few dollars on most networks and higher on Ethereum and Bitcoin, but Polymarket's own sources give different figures. For Ethereum, the Help Center says $20, the developer docs say $7, and the live deposit system showed $3 on September 24, 2026. Go by the minimum shown on the deposit screen.
Don't send less than the minimum. The Help Center says a smaller deposit stays pending until your deposits add up to the minimum, while the docs say it won't be processed.
Paying by card or bank goes through a third-party on-ramp that buys the crypto for you. Polymarket integrated MoonPay in 2024 for debit and credit cards, Apple Pay, Google Pay, bank transfer and, in some regions, PayPal; the options shown on the deposit screen may differ from this list.
The on-ramp charges its own fees under its own terms. MoonPay's published European pricing, for example, lists processing fees of up to 4.5% for cards and PayPal and up to 1% for bank transfers, with a minimum fee of €3.99, plus a network fee. Card deposits can therefore cost noticeably more than sending crypto you already hold.
Polymarket's docs are explicit: there are no Polymarket fees to deposit or withdraw. The costs you can still meet come from elsewhere:
Trading fees are separate: see Polymarket fees explained and the fee calculator.
Withdrawing sends pUSD out of Polymarket as crypto to an address you control. The Help Center's steps:
You can withdraw to EVM networks such as Ethereum, Arbitrum, Base and Optimism, and to Solana, Bitcoin and Tron; the tokens on offer depend on the network. Polymarket's docs call withdrawals instant and free: Polymarket takes no withdrawal fee, though the conversion out of pUSD is priced through a trading pool and network costs can apply. No minimum withdrawal is published.
Only your available balance can be withdrawn. Money in open positions comes free when you sell the shares, or when the market resolves and you redeem winning shares.
For large amounts, the docs note that the conversion pool can run short. If a withdrawal fails, try smaller amounts or wait for the pool to rebalance; for more than $50,000, Polymarket suggests splitting the withdrawal or using a third-party bridge.
Many people withdraw to a crypto exchange account. Transfers sent to the wrong network or address can't be reversed, so check three things first:
These are general crypto transfer practices rather than Polymarket's own wording. The exchange's own rules, minimums and any identity checks also apply.
Polymarket's support team can be reached at [email protected] or through the chat on polymarket.com. Only use Polymarket's official addresses, and be wary of links posted in comments or messages that lead to look-alike login pages.
The US app is a different product with separate accounts, run by a CFTC-regulated exchange, and it uses US dollars and bank rails instead of crypto. You must pass identity verification before depositing: name, date of birth and address, and in some cases a photo ID and selfie, with manual reviews taking up to 3–5 business days.
Deposits: debit card, bank transfer (ACH via Aeropay) or wire, always from an account in your own name. Card and ACH deposits are limited to $25,000 per transaction, $50,000 per day and $2,000,000 per rolling 60 days; part of the amount is available to trade right away, and the full deposit clears in 3–4 business days. Wires have a $1,000 minimum and are usually processed within 1 business day of being received. The docs don't list deposit fees; your bank may charge its own.
Withdrawals: free, to debit card, ACH or wire. They must go back to the same method you deposited with, are processed in the order your deposits were made, and can't include deposits that haven't cleared. Card and ACH withdrawals take 3–4 business days, and wires take 1 business day; all withdrawals go through an anti-money-laundering review that can slow them down.
If a US deposit is still pending after 5 business days, Polymarket US asks you to contact support at [email protected] or through in-app chat.
We found no Polymarket page explaining which tax forms either product issues. Don't assume winnings are tax-free because they were paid in crypto or never left the platform. Keeping your own record of deposits, withdrawals and trades makes any filing easier.
Kalshi runs on US bank rails, much like the Polymarket US app: ACH transfers carry no Kalshi fee, and money comes back to your bank. Polymarket.com runs on crypto, so moving money means choosing networks and addresses rather than bank accounts. See how to withdraw from Kalshi and our side-by-side comparison.
On polymarket.com, open Deposit, choose a method, pick the token and network, copy your deposit address and send at least the minimum; the funds are converted to pUSD on Polygon, usually within minutes. You can also pay by card or bank through a third-party on-ramp, which charges its own fees. US residents use the separate Polymarket US app, funded by debit card, ACH or wire.
No. Polymarket's docs say it charges no fees to deposit or withdraw. Network fees, bridge or conversion costs and card on-ramp fees can still apply, and trading fees are separate.
A few dollars on most networks and more on Ethereum and Bitcoin, but Polymarket's own sources disagree: for Ethereum the Help Center says $20, the docs say $7, and the live system showed $3 on September 24, 2026. Use the minimum shown on the deposit screen, and don't send less.
On polymarket.com, Polymarket's docs describe withdrawals as instant, though network conditions can add time and large amounts may need to be split. On the US app, card and ACH withdrawals take 3–4 business days and wires take 1 business day.
Yes, by sending a token the exchange accepts, such as USDC, on a network both sides support, to the exchange's deposit address for that exact token and network. Don't send pUSD, which isn't listed on exchanges. Send a small test first, because transfers to the wrong network or address can't be reversed.
Sometimes. Polymarket's recovery tool handles some tokens sent on Ethereum and Polygon, and support can look at cases on Base, Arbitrum, Optimism and BNB Smart Chain, though not every case can be recovered. Funds sent on other networks can't currently be recovered.
Polymarket's help center describes no ID step for signing up or moving funds on polymarket.com, but its terms let Polymarket request information, for example to confirm you aren't a restricted person, and card on-ramps apply their own terms. The US app requires identity verification before you deposit.
It depends on the restriction, according to Polymarket's help center. In close-only countries, users can close existing positions but can't open new ones; in Germany, existing positions must be held until the market resolves, after which funds can be withdrawn. Using a VPN to get around restrictions is prohibited by Polymarket's terms.
