What currency does Polymarket use?
Last updated July 2026 · The Cent Signals desk
The short answer
Polymarket denominates every trade on its original market in USDC, a US dollar-pegged stablecoin issued by Circle and settled on the Polygon blockchain. Since 2026 your balance is held as pUSD, an on-chain wrapper representing a one-for-one claim on that USDC. The separate regulated Polymarket US venue cash-settles in ordinary US dollars instead. Cent Signals is a free, independent desk that tracks Polymarket activity and explains how prediction markets price probability, not trading advice.
USDC is the settlement currency
On the original on-chain market, prices, deposits, balances, and payouts are all measured in USDC. USDC is a stablecoin: a token issued by the regulated firm Circle that is meant to hold a value of about one US dollar, backed by reserves of cash and short-term US Treasuries. Because one USDC tracks one dollar, a share that costs forty cents costs forty cents of USDC, and the dollar figures you see on a market page are real quantities of that stablecoin rather than a rough conversion.
Polymarket's own help center explains the choice plainly: USDC is pegged one-to-one to the dollar, which shields a balance from the volatility of other cryptocurrencies; it is backed by reserved assets and issued under regulatory standards; and every transaction is recorded publicly on-chain. That last property is the one this desk relies on. The activity we read, from large-wallet trades to the prices on our markets index, is public precisely because it settles in a token on a public blockchain.
pUSD, the collateral layer under your balance
As of 2026 there is a second name to know. Polymarket's technical documentation describes pUSD, or Polymarket USD, as the collateral token used for all trading on the platform. It is a standard ERC-20 token on Polygon that acts as a wrapper around USDC: the documentation calls it a wrapper that represents a USDC claim, with the underlying USDC settled natively and the wrapping and unwrapping enforced on-chain by two contracts named CollateralOnramp and CollateralOfframp.
The distinction matters for accuracy but not for the day-to-day experience. Polymarket states there is no algorithmic peg and no fractional reserve behind pUSD; its one-for-one relationship to USDC is enforced by the contracts themselves, and a holder can unwrap back to USDC. In the documentation's words, day to day nothing changes: you load funds, see a balance, trade, and withdraw, with pUSD sitting underneath as the settlement layer. So when a reader asks what currency Polymarket uses, the honest answer is USDC, now routed through the pUSD collateral wrapper.
Whichever asset and chain the money arrives on, the bridge converts it to pUSD on Polygon, and each chain carries its own dollar floor before a deposit will credit. Those thresholds, and the separate share-count floor the order book applies, are measured in what is the minimum deposit on Polymarket.
USDC, pUSD, and US dollars, side by side
Three money forms turn up in conversations about Polymarket, and they are easy to blur together. The table describes what each one is and where it applies. Rows that depend on the current setup are marked as of 2026.
| Attribute | USDC | pUSD | US dollars |
|---|---|---|---|
| What it is | Dollar-pegged stablecoin (Circle) | On-chain wrapper for a USDC claim | Ordinary fiat US dollars |
| Where it applies (as of 2026) | On-chain market on Polygon | On-chain balance and collateral | Regulated Polymarket US venue |
| Value vs the dollar | About 1:1, market-priced | 1:1, enforced on-chain | Exactly the dollar |
| Backing | Cash and short-term Treasuries | The underlying USDC it wraps | The banking system |
| Is it crypto | Yes, an ERC-20 token | Yes, an ERC-20 token | No |
| Bank or SIPC insured | No | No | Per the venue's arrangements |
The regulated Polymarket US exchange, which relaunched on December 2, 2025, sits in the third column: it takes and settles actual US dollars rather than a stablecoin, so a user there never touches USDC or pUSD. For how that venue differs in structure and access, see is Polymarket legal in the US.
Why the currency is measured in cents
Because the settlement asset holds a value of about one dollar, every Polymarket share is priced between zero and one dollar, and that price reads directly as an implied probability. A YES share at eight cents of USDC corresponds to roughly an eight percent implied chance the market assigns the outcome; a NO share on the other side of the same market fills out the rest. You can see this on a live market such as the market on a 25 basis point Fed rate cut after the July 2026 meeting, where the cent price is the crowd's implied chance as of the latest snapshot. For the full walk-through of the price-as-probability idea, see how to read implied probability on Polymarket.
The stablecoin denomination is also why costs on the platform are quoted the way they are. The category-based taker fee and the bid-ask spread are both taken out of that same USDC, not a separate credit system; for the detail, see Polymarket fees explained. And because the money sits in a wallet you control rather than a house account, it is worth understanding the Polymarket proxy wallet that holds your USDC and outcome tokens.
What the currency choice does and does not guarantee
A dollar-pegged stablecoin removes the price swings of a volatile cryptocurrency, but it is not the same as a bank balance. USDC is not an FDIC-insured deposit and a market position is not SIPC-protected; the peg depends on Circle's reserves holding, and the funds live on a blockchain rather than in a chartered bank. Those are ordinary facts about a stablecoin, described here so the picture is complete rather than to steer anyone toward or away from anything.

Frequently asked questions
What currency does Polymarket use?
The original on-chain market denominates every trade in USDC, a US dollar-pegged stablecoin issued by Circle and settled on the Polygon blockchain. Since 2026 the balance you see is held as pUSD, an on-chain wrapper that represents a one-for-one claim on that USDC. The separate CFTC-regulated Polymarket US venue instead cash-settles in ordinary US dollars. No national currency changes hands on the on-chain market itself.
Is Polymarket real money?
USDC is real money in the sense that each unit is meant to be backed one-for-one by cash and short-term US Treasuries held in reserve by Circle, a regulated issuer, and can be redeemed for dollars. It is not, however, a bank deposit or fiat in an account; it is a stablecoin recorded on a public blockchain. A position priced at forty cents describes forty cents of that stablecoin at risk per share.
What is pUSD on Polymarket?
pUSD, or Polymarket USD, is the collateral token used for trading on the on-chain platform as of 2026. Polymarket's documentation describes it as a standard ERC-20 wrapper that represents a USDC claim, with wrapping and unwrapping enforced on-chain by its CollateralOnramp and CollateralOfframp contracts and no algorithmic peg or fractional reserve. Day to day the experience is unchanged: you load funds, see a dollar balance, and withdraw.
Do you need cryptocurrency to use Polymarket?
On the on-chain market, funds are held and settled as USDC on Polygon, so value moves as crypto even when a card on-ramp converts dollars for you at deposit. Polymarket's help center states the platform uses USDC because it is pegged to the dollar, backed by reserved assets, and recorded publicly on-chain. The regulated Polymarket US venue takes and settles ordinary US dollars, so no stablecoin is required there.
Does Polymarket use USD or USDC?
Both, depending on the venue. The original on-chain market prices and settles in USDC, held under the hood as pUSD, and shows you a dollar-denominated balance because USDC tracks the dollar one-for-one. The CFTC-regulated Polymarket US exchange, which relaunched on December 2, 2025, deals in actual US dollars. The prices look the same because a share still ranges between zero and one dollar in either case.
