Funding a Polymarket account requires depositing cryptocurrency or fiat currency into the platform, with the exact method depending on whether you are using Polymarket’s international exchange or its regulated US platform.
The international version accepts crypto deposits across 22 tokens and 13 blockchain networks, while Polymarket US accepts debit cards, ACH bank transfers, wire transfers, and Apple Pay.
As of May 2026, the deposit process looks different than it did even a few months ago. Polymarket completed a major infrastructure upgrade on April 28, 2026, migrating its trading collateral from USDC.e to a new platform-native stablecoin called pUSD, backed 1:1 by USDC.
The user-facing experience remains dollar-denominated, but the technical layer underneath has changed, and existing users needed a one-time conversion prompt when they logged back in.
A first-time depositor sending $100 from Coinbase to Polymarket International will pay under $0.01 in network fees and see the balance appear in roughly two minutes.
The same $100 deposited via debit card on Polymarket US arrives instantly with zero platform fees but may carry a processing fee from the card issuer. The right method depends on which version of Polymarket you can access, what payment rails you already have, and how much you care about fees.
Key Takeaways
Here is what matters most before your first deposit.
- Polymarket International and Polymarket US are separate platforms with completely different funding methods.
- The cheapest way to fund the international platform is a direct USDC transfer on the Polygon network, costing under $0.01.
- Polymarket US accepts fiat deposits via debit card, ACH, wire transfer, and Apple Pay with no Polymarket-charged fees.
- All balances on the international exchange now settle in pUSD, Polymarket’s new collateral token, after the April 2026 V2 upgrade.
- Sending funds on the wrong blockchain network or to the wrong address results in permanent loss with no recourse.
Two platforms, two funding paths
Polymarket now operates two distinct platforms, and confusing them is the most common mistake new users make. Polymarket International is the original crypto-native exchange that settles trades on the Polygon blockchain.
It is accessible in most countries outside the United States. Polymarket US is a separate, CFTC-regulated platform that launched after Polymarket received an Amended Order of Designation from the CFTC in November 2025, enabling intermediated access through futures commission merchants (FCMs) and brokerages.
The funding flows for each platform share almost nothing in common. International users deposit crypto to a wallet address. US users deposit fiat through traditional payment rails. If you are using Polymarket in the US, the experience resembles a standard brokerage deposit rather than a crypto transaction.
How to fund Polymarket International
The international platform accepts deposits in 22 different tokens across 13 blockchain networks. Whatever you send, whether it is USDC, USDT, ETH, BTC, SOL, or one of the other supported assets, gets automatically converted to pUSD on arrival. Day to day, your balance still reads in dollars, priced from $0.01 to $0.99 per share.
There are three primary ways to get funds onto the international platform.
Crypto wallet transfer
This is the cheapest method. Log into Polymarket, click “Deposit,” and copy your unique deposit address (a string starting with “0x”). Then go to your crypto wallet or exchange, select “Send” or “Withdraw,” paste the Polymarket address, and choose the Polygon network. Gas fees on Polygon typically run under $0.01, and the transfer confirms in under a minute.
MetaMask, Rabby, Trust Wallet, and Phantom all work. If you are sending from an exchange like Coinbase, Kraken, or Binance, make sure the exchange supports Polygon withdrawals for your chosen token. If it does not, you will need to bridge from Ethereum, which adds cost and time. For a full walkthrough on wallet options, see our guide to setting up a non-custodial Web3 wallet for Polymarket.
Coinbase Connect
Polymarket offers a direct Coinbase integration through a secure third party called Fun.xyz. In the deposit modal, tap “Connect Exchange,” authorize through Coinbase with two-factor authentication, choose your amount, and confirm.
Funds arrive in roughly two minutes with low fees. Your Coinbase credentials are never stored by Polymarket. Binance, Kraken, Gemini, and Gate integrations have been announced but are not yet live as of May 2026.
Credit or debit card (on-ramp)
If you do not hold any crypto, Polymarket integrates with on-ramp providers like MoonPay and Transak that convert your card payment directly into your Polymarket balance.
In the deposit modal, click the “Use Cash” tab, select your card, enter the dollar amount, and complete payment. Processing fees run 2% to 4% depending on the provider, card type, and country. Deposits typically arrive within 5 to 15 minutes.
US-based users cannot use the card on-ramp on the international platform due to compliance restrictions. This method is designed for international users who want to skip the crypto setup entirely.
How to fund Polymarket US
Polymarket US works more like a traditional exchange account. After completing mandatory KYC verification (government ID, Social Security Number, proof of residency), you can fund your account with standard payment methods.
Polymarket US does not charge any deposit fees, though your bank or card issuer may apply their own processing charges.
The supported deposit methods and their current limits are listed below.
| Deposit Method | Processing Time | Daily Limit | Polymarket Fee |
|---|---|---|---|
| Debit card | Instant | $50,000 | $0 |
| Bank transfer (ACH) | Instant | $50,000 | $0 |
| Wire transfer | Instant | No listed limit | $0 |
| Apple Pay | Instant | $50,000 | $0 |
All deposits must come from accounts in your own name and may be subject to verification checks. One important detail: even though deposits show as instant buying power, withdrawals are only available after the deposit has fully cleared, which typically takes 3 to 4 business days.

What the pUSD migration means for deposits
On April 28, 2026, Polymarket rolled out its largest infrastructure upgrade since launch. The platform migrated from USDC.e to pUSD as its collateral token and replaced the original trading system with CTF Exchange V2, a rebuilt central limit order book. The new smart contracts were audited by Cantina and Quantstamp before going live.
For depositors, the practical change is minimal. When you deposit USDC or any other supported token, it still converts automatically into your trading balance at a 1:1 dollar rate. The difference is that the underlying collateral is now pUSD rather than USDC.e.
Existing users who logged in after the upgrade saw a one-time prompt to convert their balance and approve the new exchange contracts. Settlement still happens in native USDC when you withdraw.
One quirk worth knowing: if you deposit “Native USDC” (Circle’s newer version on Polygon) rather than the older Bridged USDC, you may see an “Activate Funds” button in your wallet. Clicking it performs a gasless swap into the trading collateral. This is a one-time step and costs nothing.
Common deposit mistakes and how to avoid them
The most expensive errors on Polymarket are deposit errors, because blockchain transactions cannot be reversed. Three mistakes account for nearly every lost deposit.
- Wrong network. Sending USDC on Ethereum mainnet to a Polygon deposit address (or vice versa) means your funds land on the wrong chain. Polymarket’s cross-chain deposit support has improved in 2026, but always verify the network selection before confirming.
- Wrong token on older wallets. Some wallets still default to tokens that Polymarket does not accept on certain chains. Double-check that the token you are sending is in the supported list before initiating the transfer.
- Manual address entry. Always use the copy button in the Polymarket interface to grab your deposit address. Typing even one character wrong sends your funds to a nonexistent or unrecoverable address.
If a deposit does not appear after the expected confirmation time, check your transaction on a block explorer like Polygonscan before contacting support. In most cases, slow deposits are caused by network congestion rather than lost funds.
Before your first deposit
The cheapest path for most international users is buying USDC on Coinbase (free via ACH), withdrawing to Polygon, and sending it to Polymarket, a process that costs under $0.01 in total fees. US users have it simpler: a debit card or Apple Pay deposit on Polymarket US costs nothing on the platform side and arrives instantly.
Either way, start small. Many experienced traders recommend funding with $50 to $100 initially while you learn how markets move.
Keep in mind that Polymarket’s fee structure varies by market category, and maker orders (limit orders) pay zero taker fees and earn daily rebates. Understanding deposit costs in isolation is useful, but the real cost picture includes trading fees, withdrawal timelines, and the spread on the order book.
Funding the account is the first step; managing what happens after the money arrives is what separates profitable traders from the rest.
