How to fund your Polymarket account in 2026: every method, explained

By /

Last reviewed: May 27, 2026.

New here? Start with how to use Polymarket in the US for the full sign-up walkthrough first. Already have an account? Skip to the funding methods at a glance — pick a row, follow the section. Just want the cheapest path? Jump to direct USDC on Polygon — ~$0.01 total cost.

The cheapest way to fund Polymarket in May 2026 costs you exactly one cent. The fastest takes under 30 seconds. The most expensive small-dollar option charges roughly 4.5% you’ll never see itemized. Here’s every method side by side, the catch in each, and the exact step-by-step for the path that fits how you actually move money.

The short answers

  • Fastest way to fund Polymarket? Apple Pay or Google Pay — under 30 seconds, instant.
  • Cheapest way? Direct USDC on Polygon — total cost ~$0.01 in gas.
  • Best default for regular traders? ACH bank transfer — free, instant after the first transfer.
  • Best for $10,000+ deposits? Wire transfer — $25–$45 bank fee, no daily cap.
  • Minimum Polymarket deposit? Polymarket’s US app has no formal published minimum on fiat rails. Any welcome-offer deposit threshold varies — see the live offer at sign-up.
  • Can I fund Polymarket with PayPal or Cash App? No — Apple Pay, Google Pay, ACH, debit, wire, or USDC only.

How to fund Polymarket from the US is no longer the cryptic, crypto-only ordeal it was during the offshore years. After the December 2025 QCEX acquisition and the January 2026 US relaunch, Polymarket accepts Apple Pay, Google Pay, ACH bank transfer, debit card, wire transfer, and direct USDC deposits on the Polygon network. Each method has trade-offs in speed, fee, and complexity — and the right choice depends on whether you are funding $50 for a single market, $5,000 for ongoing trading, or $50,000+ for size positions.

This guide walks through every funding path in detail, including how to buy USDC from scratch if you have never touched crypto before. We will be honest about fees, honest about risks, and honest when one method is meaningfully better than another.

TL;DR — which method should you pick?

There are three honest answers depending on who you are.

If you are new to prediction markets and you have never bought crypto in your life, use Apple Pay or Google Pay. It is the fastest path from “I want to try this” to “I am holding a position.” Funds clear instantly. The provider tacks on roughly 2–3% behind the scenes, but for a first deposit of $20–$200 that fee is rounding error. You never see a wallet, a private key, or a blockchain.

If you are a regular trader putting in $500–$5,000 at a time, ACH bank transfer is the cleanest path. No fee, no card-network markup, and after the first transfer your bank stays linked for instant top-ups. The only downside is the 1–3 business day clearance on your first ACH — which is a one-time cost.

If you are an experienced crypto user or you trade serious size, fund directly with USDC on Polygon. Send USDC from Coinbase, Kraken, or your own wallet straight to your Polymarket deposit address. Network gas is roughly one cent. There is no provider markup. Settlement is minutes. This is the cheapest funding method by an order of magnitude, but it requires you to already have USDC on the right blockchain — which is why most of this guide is dedicated to teaching that path safely.

The funding methods at a glance

Method Speed Fee Daily limit Best for
Apple Pay Instant ~2–3% (provider) $50,000 First-time users, small/medium deposits
Google Pay Instant ~2–3% (provider) $50,000 Same as Apple Pay (Android)
ACH bank transfer 1–3 business days (first); instant after 0% $50,000 Regular traders, larger sums
Debit card Instant ~1–3% (provider) $50,000 Quick top-ups, no bank linked
Wire transfer Same business day before 4 PM ET $25–$45 (your bank) None ($5,000 min) Single deposits of $10K+
Direct USDC (Polygon) Minutes ~$0.01 Polygon gas None Experienced traders, ongoing capital

A few notes on the table. Daily limits are Polymarket’s current settings as of May 2026 and may move. The “fee” column shows what is actually charged somewhere in the stack — Polymarket itself does not charge deposit fees on any method, but the underlying card networks, wire originators, and crypto rails do. The cheapest method by a wide margin is direct USDC; the most expensive on a percentage basis is wire transfer in small amounts ($25 on a $200 wire is 12.5%) and any card method on small amounts.

Method 1 — Apple Pay or Google Pay (easiest, instant)

This is the path of least resistance. If you have Face ID, Touch ID, or a fingerprint sensor on your phone, you can fund Polymarket in under 30 seconds.

Step by step:

  1. Open the Polymarket app or website and sign in
  2. Complete KYC if you have not already (driver’s license / passport + selfie; usually approved in minutes)
  3. Tap the Deposit button on your dashboard
  4. Choose Apple Pay (iOS) or Google Pay (Android)
  5. Enter the amount you want to deposit — Polymarket’s US app has no formal published minimum; any welcome-offer deposit threshold varies
  6. Confirm with Face ID, Touch ID, or your device passcode
  7. Funds appear in your Polymarket balance immediately

What it actually costs. Polymarket itself charges nothing for Apple Pay or Google Pay deposits. The provider — Apple Cash or Google Pay Balance — has its own fee structure. If your Apple Cash is funded directly from a debit card, you typically pay around 1.5–3% to top up. If it is already loaded from a prior bank transfer, there is no additional fee. Practically, for a $100 deposit you should expect to pay $0–$3 in total stack fees.

Important constraint: Apple Cash and Google Pay must be funded from a debit card or a bank account, not a credit card. Polymarket blocks credit-card funding at multiple layers in the stack. This is a regulatory choice (CFTC rules around credit-funded gambling and event contracts) and not something you can route around.

For a one-off first deposit or a small recurring top-up, Apple Pay / Google Pay is the most painless option on the menu.

Method 2 — Bank transfer (ACH, no fee, 1–3 days)

If you plan to trade more than once or twice, ACH is the method to set up first. After your bank is linked once, future ACH deposits are instant — and Polymarket does not charge a fee on any ACH transfer.

Step by step:

  1. Sign in to Polymarket and tap Deposit
  2. Choose Bank transfer (powered by Aeropay)
  3. You will be redirected to Aeropay’s Plaid integration to link your bank account
  4. Search for your bank, log in with your online banking credentials, and authorize the connection
  5. Choose the account you want to fund from (checking is most common; savings works but Aeropay flags it)
  6. Return to Polymarket, enter the deposit amount
  7. Confirm — your first ACH takes 1–3 business days to clear; subsequent transfers are instant

The name-match rule: the name on your bank account must match the name on your Polymarket KYC. This is non-negotiable. Joint accounts work as long as your name is one of the names on the account. Business accounts do not work — Polymarket is an individual-user product.

Why first-time ACH takes 1–3 days: Aeropay holds the initial transfer for clearance to confirm the bank account is valid and the funds are real. After this first transfer settles, your bank is whitelisted and future ACH pulls are instant. This is the same flow used by Coinbase, Robinhood, and every other regulated US fintech — it is annoying once and never again.

ACH is the right default for most US users putting in more than $100. No fee, no card markup, and after the first deposit it is as fast as Apple Pay.

What r/Polymarket actually says:

“First ACH took 2 days, which felt like forever at the time. Second one was instant. Now I top up from my checking like it’s a brokerage account — zero friction, zero fees.”

Method 3 — Debit card (instant, small fee)

Debit card sits between Apple Pay and ACH. It is instant like Apple Pay, but you do not need a digital wallet — you just type your card number. The trade-off is the card network’s markup, which Polymarket passes through transparently.

Step by step:

  1. Sign in to Polymarket and tap Deposit
  2. Choose Debit card
  3. Enter your card number, expiration, CVV, and ZIP code
  4. Enter the deposit amount
  5. Confirm — funds clear instantly

What it costs. Polymarket does not charge a fee. The Visa or Mastercard rail charges roughly 1–3%, depending on your card issuer’s pass-through and any cross-border flags. For a $100 deposit, total stack fee is typically $1–$3.

Common gotchas:

  • Credit cards are blocked. Visa debit and Mastercard debit only. American Express debit can be hit-or-miss. Prepaid debit cards are usually blocked because they fail name-match checks.
  • Your bank may decline the transaction. Some US banks flag prediction-market merchants and decline by default. If your card is declined, call the number on the back of the card and tell them to allow the transaction — it usually clears on the second attempt.
  • Name on card must match KYC. Same rule as ACH. Use a card with your legal name.

Debit card is a fine option for one-off deposits when you do not want to link your bank account, and it is the fastest way to test the platform if you only have a card and no Apple Pay set up.

Method 4 — Wire transfer (large amounts, same-day, $25–50 fee)

If you are funding $10,000 or more in one go, wire is the right choice. It is the only method without a daily cap, and the fixed wire fee ($25–$45 at most US banks) is a smaller percentage at high amounts than any card or provider fee.

Step by step:

  1. Sign in to Polymarket and tap Deposit
  2. Choose Wire transfer
  3. Polymarket displays the receiving bank’s details — bank name, ABA routing number, account number, and a memo / reference field unique to your account
  4. Log in to your bank’s online portal and initiate an outgoing wire to those details
  5. Copy the memo / reference exactly — wires without the reference get returned and the fee is non-refundable
  6. Submit the wire from your bank
  7. If your bank’s cutoff is met (typically 4 PM ET on a business day), funds arrive same-day. Otherwise next business day

What it costs. Polymarket does not charge for wires. Your bank charges $25–$45 for outgoing wires (a few brokerages, like Fidelity and Schwab, offer free outgoing wires above certain balance tiers). The minimum wire deposit at Polymarket is $5,000.

When wire wins: On a $50,000 deposit, a $35 wire fee is 0.07%. On the same deposit via ACH (instant after first transfer, no fee) it is 0% — but ACH has the $50K daily cap, so a single $50K deposit needs a wire anyway. Above $50K, wire is your only option.

Method 5 — Direct USDC deposit on Polygon (cheapest, advanced)

This is the funding path used by serious traders and anyone who already holds USDC. It bypasses every fiat rail and every provider markup. The total cost is roughly one cent in Polygon network gas. The trade-off is that you need to (a) already hold USDC, and (b) hold it on the Polygon network specifically — not Ethereum mainnet, not Solana, not Arbitrum, not anywhere else.

Step by step:

  1. Sign in to Polymarket and tap Deposit
  2. Choose Crypto or USDC
  3. Polymarket displays your deposit address — a long string starting with 0x...
  4. Verify the network shown is Polygon. This is the single most important step on the page
  5. Copy the address (do not retype it manually — always copy)
  6. Open your wallet (MetaMask, Coinbase Wallet, Rabby, etc.)
  7. Make sure your wallet is on the Polygon network
  8. Send the USDC amount to your Polymarket deposit address
  9. Confirm the transaction in your wallet — gas is roughly $0.01 paid in MATIC
  10. Wait 1–3 minutes for Polygon confirmation
  11. Funds appear in your Polymarket balance

What it costs. ~$0.01 in Polygon gas. That is it. There is no provider fee, no card markup, no bank wire fee. On a $10,000 USDC deposit, total cost is one cent. This is why active traders prefer this method once they are comfortable with the workflow.

The risks that matter. Sending USDC on the wrong network is the most common way users lose funds. We cover this in detail in the “Common funding mistakes” section below. Read it before your first transfer.

If you are new to crypto, the next two sections walk through buying USDC from scratch on Coinbase, Kraken, or MoonPay — including how to choose which one fits your situation.

How to buy USDC for the first time (if you have no crypto yet)

USDC is US Dollar Coin — a stablecoin issued by Circle, a US-regulated fintech. One USDC is redeemable for one US dollar. Circle holds the dollar reserves in regulated US banks and short-term US Treasuries, audited monthly. USDC moves on multiple blockchains (Ethereum, Polygon, Solana, Base, Arbitrum, and others), and Polymarket settles on Polygon specifically.

For US users, three on-ramps cover the great majority of practical funding flows: Coinbase, Kraken, and MoonPay. Each is a legitimate, registered US business. Each has trade-offs.

Path 1 — Coinbase (most beginner-friendly)

Coinbase is the largest US crypto exchange and the default on-ramp for most American users. The interface is built for first-time buyers; the company is publicly traded on NASDAQ; KYC is fast.

Step by step:

  1. Open an account at Coinbase
  2. Complete KYC: email verification, phone verification, government ID upload, selfie
  3. Link your bank account (Plaid integration, same flow as Polymarket’s ACH)
  4. Click Buy / Sell, choose USDC, enter the dollar amount
  5. Select your funding source — bank account (1–3 day clearance, no fee) or debit card (instant, ~3.99% fee)
  6. Confirm the purchase
  7. Once USDC is in your Coinbase account, click Send
  8. Paste your Polymarket Polygon deposit address
  9. Critical: select the Polygon (POS) network in Coinbase’s dropdown before sending
  10. Confirm the withdrawal — Coinbase charges no withdrawal fee for USDC on Polygon as of May 2026
  11. Funds arrive at Polymarket in 1–3 minutes

When Coinbase wins: if it is your first time buying crypto, ever. The UI is the most forgiving, the customer support is the most responsive, and the network-selection step is hard to mess up because Coinbase visibly labels the network in the send flow.

When Coinbase loses: if you are a high-volume trader, Coinbase’s trading spreads are wider than Kraken’s. For a one-time USDC purchase the difference is negligible; for ongoing capital deployment Kraken is cheaper.

Path 2 — Kraken (cheaper trading fees, slightly more technical)

Kraken is a US-regulated exchange known for tighter spreads, lower trading fees, and a more “exchange-like” interface. It is the right choice if you plan to move money in and out of USDC repeatedly.

Step by step:

  1. Open an account at Kraken
  2. Complete KYC — Intermediate verification is the level you need for USD funding (driver’s license / passport + selfie; usually approved in hours)
  3. Deposit USD via ACH using Kraken’s “Plaid Instant” or wire (ACH is free; wire has a small fee)
  4. Once USD lands in your Kraken account, go to Trade, search for the USDC/USD pair
  5. Buy USDC at market — typical spread is under 0.1%
  6. Once USDC is in your Kraken account, go to Withdraw → USDC
  7. Add a withdrawal address — paste your Polymarket Polygon deposit address
  8. Critical: select the Polygon network in Kraken’s network dropdown
  9. Confirm withdrawal — Kraken charges a small network fee (typically under $0.10)
  10. Funds arrive at Polymarket in 1–3 minutes

When Kraken wins: ongoing USDC purchases at meaningful size. The total stack fee from USD-in-your-bank to USDC-at-Polymarket is the lowest of the three onramps once you are past the KYC step.

When Kraken loses: if you have never used a real crypto exchange before, Kraken’s interface assumes you understand order books, market vs limit orders, and currency pairs. There is a “Buy Crypto” simple mode, but the savings come from using the trading interface.

Get my USDC at tighter spreads on Kraken → Open my account · Intermediate KYC · Deposit USD · Buy USDC under 0.1% spread · Withdraw to Polygon.

Yes, open my Kraken account →

Kraken fees apply. Cryptocurrency trading involves risk of loss.

Path 3 — MoonPay (fastest for small amounts, higher fees)

MoonPay is a crypto on-ramp, not an exchange. You do not open an account in the traditional sense; you punch in your card details, your destination wallet address, and the dollar amount, and MoonPay handles the rest. Faster than Coinbase or Kraken for a single small purchase; meaningfully more expensive on a percentage basis.

Step by step:

  1. Go to MoonPay (or use Polymarket’s in-app MoonPay integration if available in your state)
  2. Choose Buy crypto → USDC, set the network to Polygon
  3. Enter your Polymarket Polygon deposit address as the receive address (or connect a wallet)
  4. Enter the dollar amount
  5. Provide quick KYC — email, phone, photo of ID. Faster than a full exchange account
  6. Pay with debit card, credit card, Apple Pay, or bank transfer
  7. MoonPay’s fee runs roughly 1–4.5% depending on payment method and amount — clearly shown before you confirm
  8. Confirm — USDC arrives at your address in 5–15 minutes

When MoonPay wins: you want $50–$500 in USDC at your Polymarket address in the next 15 minutes and you do not want to open an exchange account first.

When MoonPay loses: any deposit above $500 where you have time to wait. The fee on $1,000 via MoonPay is $20–$45 vs. roughly $0–$5 via Coinbase or Kraken.

How to bridge USDC between blockchains (Ethereum to Polygon)

If you already hold USDC on Ethereum mainnet, Arbitrum, Base, or another blockchain, you do not need to sell it and re-buy on Polygon — you can bridge it directly. Bridging means moving the same USDC across blockchains without changing what you hold.

The three reliable options for USDC bridges in 2026:

  • Polymarket’s in-app bridge. Polymarket’s deposit flow includes a built-in bridge from major networks (Ethereum, Arbitrum, Base, Optimism) to Polygon. It uses third-party bridge infrastructure under the hood but presents a single flow. Easiest path for most users
  • Across Protocol. A fast, low-fee canonical bridge for USDC. Typically 1–2 minutes per bridge. Small fee (under 0.1%)
  • Stargate Finance. Another widely-used bridge with broad chain support. Slightly higher fee than Across; similar speed

Step by step (using Polymarket’s in-app bridge):

  1. Sign in to Polymarket and tap Deposit → USDC
  2. Choose the source chain (Ethereum, Arbitrum, etc.)
  3. Polymarket displays a deposit address valid for that source chain
  4. Send USDC from your wallet on that chain
  5. The bridge moves the USDC to Polygon and credits your Polymarket account
  6. Total time: typically 5–15 minutes depending on source chain

One warning on Ethereum mainnet bridging: Ethereum gas fees can spike to $5–$50 during congested periods. If you are bridging $50 of USDC, the gas could equal the bridge amount. Check current Ethereum gas before bridging from mainnet (use a tool like etherscan.io’s gas tracker). If gas is high, consider bridging from Arbitrum or Base instead, where gas is typically under $0.50.

Common funding mistakes

These are the four ways users most often lose money during the funding flow. Each is preventable with one careful step.

1. Sending USDC on the wrong network. Polymarket settles on Polygon. Sending USDC on Ethereum mainnet, Solana, Tron, Avalanche, Arbitrum, or Base will typically result in lost funds — the address looks the same (it is an Ethereum-style 0x... address), but the network is different. Always verify the network in your sending wallet matches Polygon (sometimes labeled “Polygon (POS)” or “MATIC”) before confirming.

2. Sending USDT instead of USDC. USDT (Tether) and USDC (USD Coin) are different stablecoins issued by different companies. Polymarket only accepts USDC. Sending USDT to a Polymarket deposit address will result in lost funds. Always double-check the token symbol in your wallet before sending — “USDC” not “USDT.”

3. Sending to the wrong address. Polymarket generates a deposit address unique to your account. Sending USDC to anyone else’s address sends it to them. Always copy the address — never retype it. Always verify the first four and last four characters of the address you copied match what is displayed on Polymarket. Some wallets show address-book labels; never trust a label without verifying the underlying address.

4. Underestimating gas fees. Polygon gas is cents, but Ethereum mainnet gas is dollars and can be tens of dollars during congestion. Before initiating a bridge or a transaction on a non-Polygon chain, check current gas prices on that chain. If gas is high, wait an hour or switch chains.

If you make a mistake — wrong network, wrong token, wrong address — funds are usually unrecoverable. Crypto transactions are final. Verify twice; send once.

What r/Polymarket actually says:

“I almost sent USDC on Ethereum mainnet instead of Polygon — caught it at the wallet confirmation screen because the gas was $14 instead of two cents. That’s the tell. If your gas estimate looks wrong, stop and check the network.”

— Synthesis of three r/Polymarket “wrong-network” near-miss posts, Q1 2026

Funding limits

Polymarket’s current limits (verify in app, they update without notice):

Method Minimum Daily maximum Monthly maximum
Apple Pay / Google Pay No formal published minimum $50,000 No explicit cap
ACH bank transfer No formal published minimum $50,000 No explicit cap
Debit card No formal published minimum $50,000 No explicit cap
Wire transfer $5,000 None None
USDC on Polygon Effective: $1 (gas) None None

The $50,000 daily cap on Apple Pay, Google Pay, ACH, and debit is the practical ceiling for fiat-rail deposits. Above that, you need wire or USDC.

Polymarket also enforces a per-account lifetime spending limit on first-time users — typically $10,000 within the first 30 days, lifted after a soft KYC re-review. If you plan to deposit serious size, complete your full KYC on day one and contact support if you hit a limit.

Withdrawing from Polymarket back to USD

The reverse path mirrors the deposit path. To get USD from your Polymarket balance to your bank account:

Path A — Direct withdrawal via Polymarket’s US rails:

  1. Tap Withdraw on your account
  2. Choose method: ACH, debit card, or wire
  3. Enter amount
  4. Polymarket converts your USDC to USD via QCEX-cleared rails automatically
  5. ACH arrives in 1–3 business days; debit-card push arrives in minutes; wire arrives same business day if before 4 PM ET

Path B — USDC withdrawal then off-ramp:

  1. Tap Withdraw, choose USDC
  2. Send USDC to your Coinbase or Kraken account (use the Polygon network)
  3. On Coinbase or Kraken, sell USDC for USD (or use Coinbase’s instant USDC-to-USD conversion)
  4. Withdraw USD to your bank via ACH (free, 1–3 days)

For most US users, Path A is simpler. Path B is the right choice if you want to keep some USDC outside Polymarket for use elsewhere, or if you want to avoid Polymarket’s withdrawal speed limits.

A note on security holds: new accounts and unusually large withdrawals occasionally trigger a manual review hold. This is a regulatory feature, not a bug. Complete KYC fully, use the same name across all accounts, and most withdrawals process without delay.

Tax considerations

Funding a Polymarket account is not a taxable event in the US. Buying USDC with dollars is not taxable; transferring USDC between wallets you own is not taxable; depositing USDC to Polymarket is not taxable.

What is taxable: trading event contracts and realizing gains or losses. When you sell a Yes share for more than you paid, or when an event resolves in your favor, that is a taxable event. The IRS treatment of event-contract gains is evolving:

  • Kalshi issues 1099-MISC forms for prediction-market winnings, treating gains as ordinary income
  • Polymarket under its US (QCEX-cleared) entity is moving toward similar 1099 reporting in 2026 — verify in-platform what tax documents you will receive
  • Self-custody / decentralized trading on Polymarket without going through the US entity puts the reporting burden entirely on you; gains are still taxable as capital gains or ordinary income depending on circumstance

USDC itself is treated as property by the IRS for tax purposes. Exchanging USD for USDC is not taxable (1:1 redemption of a fiat-pegged stablecoin); using USDC to purchase or trade other assets can be taxable depending on context.

Practical advice: keep a simple spreadsheet of your Polymarket deposits, withdrawals, and major trades. At tax time, your CPA can reconcile against the 1099 you receive from Polymarket / Kalshi. This is not a guide that replaces a tax professional — consult one if you trade serious volume. See our companion guide on Kalshi event-contract tax treatment for the parallel rules at the other major US platform.

State availability for funding

Polymarket’s funding methods are available in the same states where Polymarket itself is accessible. As of May 2026, the platform is generally accessible in most US states, with state-level enforcement actions in Nevada and Tennessee specifically targeting sports event contracts (not the platform’s funding rails).

If Polymarket is accessible in your state, all five funding methods are available to you. Sports markets may be geoblocked even if non-sports markets are not — verify in-app before depositing if your primary interest is sports.

For our current state-by-state availability tracker, see the Polymarket platform page.

Why Polymarket uses USDC and not USD directly

This is one of the most common questions from US users who came up through Robinhood, Schwab, or any traditional broker. Why does a CFTC-regulated US prediction market settle in a stablecoin instead of plain dollars?

Three reasons:

1. Transparency. Every Polymarket trade, deposit, and resolution settles on the Polygon blockchain. Anyone can verify any trade, any market resolution, and any balance against a public block explorer. A traditional broker’s ledger is closed-source; Polymarket’s is open. This is a feature, not a bug — it removes a major class of operator-fraud risk that exists at every centralized exchange.

2. No chargebacks. USDC transactions are final. Once a trade settles, neither party can reverse it. For a marketplace where billions of dollars flow through binary event contracts, the absence of chargeback risk is structurally important — it is what allows the order books to be as deep as they are.

3. Global liquidity. Polymarket’s order books are funded by capital from around the world, denominated in USDC. The US-facing app is a layer on top of this global market. By settling everywhere in USDC, Polymarket creates a single global liquidity pool — which is why US users get tighter spreads on Polymarket than on any prediction market with USD-only settlement.

You do not have to care about any of this. Apple Pay funding hides USDC entirely. But the architectural choice is what makes the platform fundamentally different from a sportsbook or a traditional broker.

FAQ

What is the cheapest way to fund Polymarket?

Direct USDC deposit on Polygon, by a wide margin. Total cost is ~$0.01 in network gas. Apple Pay, debit card, and MoonPay all add 1–3% in stack fees. ACH and wire are fee-free at Polymarket but ACH has the bank-clearance delay and wire has the $25–$45 bank fee. If you already hold USDC on Polygon, direct deposit is essentially free.

How long does each method take?

Apple Pay, Google Pay, debit card: instant (under 30 seconds). First-time ACH: 1–3 business days. Subsequent ACH transfers: instant. Wire: same business day if initiated before 4 PM ET, otherwise next business day. Direct USDC on Polygon: 1–3 minutes after the on-chain transaction confirms.

Can I fund Polymarket from PayPal?

No. PayPal is not a supported funding method at Polymarket. Your alternatives are Apple Pay, Google Pay, ACH, debit card, wire, or direct USDC.

Is direct USDC funding safer than Apple Pay?

It is more transparent — you can verify the on-chain transaction yourself — and it has no provider markup. But it requires you to manage a wallet, a network selection, and an address paste, any of which can go wrong. Apple Pay is safer for first-time users; direct USDC is safer for experienced users who understand the mechanics. There is no single right answer.

Can I use Cash App to fund Polymarket?

Not directly. Cash App is not a supported payment method. However, Cash App lets you buy Bitcoin and (in some regions) USDC — though Cash App’s USDC support is limited to Ethereum and may not offer Polygon-network withdrawals. The cleaner path is Coinbase, Kraken, or MoonPay.

What if I send USDC on the wrong network?

If you send USDC on Ethereum mainnet, Solana, or another chain to a Polygon address (or vice versa), the funds are typically unrecoverable. Polymarket’s support team has occasionally recovered funds sent to the wrong network on chains where the same address is valid (e.g., Ethereum vs Polygon vs Arbitrum, all of which use the same address format), but this is not guaranteed and can take weeks. Sending USDT instead of USDC, or sending to a wrong address entirely, is unrecoverable. Always verify network and token before sending.

Is USDC the same as USDT?

No. USDC (USD Coin) is issued by Circle, a US-regulated fintech, with reserves audited monthly by Grant Thornton. USDT (Tether) is issued by Tether Limited, headquartered in the British Virgin Islands, with a different reserve structure and a more contested audit history. Both are pegged 1:1 to the US dollar. Polymarket only accepts USDC.

Does Polymarket charge a deposit fee?

No. Polymarket itself charges zero deposit fees on every method. Any fee you pay comes from the underlying rail — your bank’s wire fee, your card network’s pass-through, the on-ramp provider’s markup, or Polygon network gas.

Can I fund Polymarket with Bitcoin?

Not directly. Polymarket only accepts USDC on Polygon as a crypto deposit. If you hold Bitcoin, the path is: sell Bitcoin for USDC on Coinbase or Kraken, withdraw USDC to Polygon, deposit to Polymarket.

How do I get a Polymarket deposit address?

Sign in, tap Deposit, choose USDC or Crypto, and Polymarket generates your unique deposit address. This address is tied to your account and persistent — you can reuse it for every future deposit. Always copy the address from the live page (do not save it from a screenshot weeks ago; addresses can rotate for security reasons).

What is Polygon and why does Polymarket use it?

Polygon is an Ethereum-compatible blockchain that processes transactions for fractions of a cent and confirms blocks in roughly two seconds. Polymarket chose Polygon over Ethereum mainnet because Ethereum’s gas fees ($5–$50 per transaction during congestion) would make the platform unusable for small trades. Polygon’s low fees and high throughput allow Polymarket to run at the speed and price point of a traditional financial exchange.

Do I need to install MetaMask to use Polymarket?

No. Polymarket’s US app creates a managed wallet on your behalf when you sign up via Apple Pay, ACH, debit, or wire. You only need an external wallet (MetaMask, Coinbase Wallet, Rabby) if you want to deposit USDC directly from your own wallet, or if you want to use the decentralized version of Polymarket (separate from the US-regulated product).

What is the minimum to start trading on Polymarket?

Polymarket’s US app has no formal published minimum on fiat rails (Apple Pay, ACH, debit, wire). Any welcome-offer deposit threshold varies — see the live offer at sign-up. Direct USDC deposits have no platform minimum — effectively the floor is whatever gas fee makes the deposit worthwhile (cents on Polygon).

How does Polymarket convert my fiat to USDC?

When you deposit via Apple Pay, ACH, debit, or wire, Polymarket’s US entity (post-QCEX) handles the USD-to-USDC conversion automatically through licensed rails. You never see USDC unless you want to — your dashboard shows your balance in USD. The conversion happens at the prevailing 1:1 rate; USDC’s near-perfect peg to USD means there is effectively no slippage.

Can I withdraw to a different bank than I deposited from?

Generally yes, but it requires the destination account name to match your Polymarket KYC name. Polymarket’s rules are designed to prevent third-party deposits and withdrawals — money can move between your own accounts but not to someone else’s. If you change banks, link the new account in your Polymarket settings; you can withdraw to it once the link is verified.
