What Is Polymarket USD (pUSD)?
pUSD is Polymarket’s dollar-pegged in-platform balance—a stablecoin-style token backed by USDC—not a volatile crypto you trade for price swings. Below: what stablecoins are, how that relates to USDC and pUSD, then funding and Polycopy.
Stablecoins: what they are and how they work
What is a stablecoin?
Most cryptocurrencies trade on supply and demand, so their price moves around. A stablecoin is different: it is issued and designed so that one token ≈ one unit of fiat—almost always one U.S. dollar. That makes it practical to deposit $100, risk $20 on a market, and know your account still reads in “dollars” without your balance jumping because the coin itself pumped or dumped. Issuers hold reserves or use other mechanisms; each design has tradeoffs and risks, which is why serious platforms name the exact asset (e.g. USDC) and publish how redemption works.
How does USDC fit in?
USDC (USD Coin) is a widely used dollar stablecoin issued by Circle. In self-custody flows you often buy or receive USDC on an exchange, then send it on a specific network—on Polymarket, that is commonly Polygon—so the platform can credit your account. You still “think” in dollars; USDC is the token that represents those dollars on-chain. Polymarket’s deposit help covers methods, networks, and limits.
So what is pUSD?
pUSD (Polymarket USD) is Polymarket’s own dollar-pegged collateral token on Polygon—stablecoin-like in purpose (track $1), but specific to Polymarket’s contracts. Polymarket states that when you deposit USDC, your in-platform trading balance is represented as pUSD, and that it is 1:1 backed by USDC with backing enforced by smart contracts (not an algorithmic “undercollateralized” stablecoin model). You swap back toward USDC when you withdraw. Day to day they describe it as invisible: you load funds, see a balance, trade, withdraw—pUSD is the technical layer underneath.

What this means for Polycopy
Polycopy is a copy-trading layer on top of Polymarket. Your capital and settlement still happen on Polymarket; we do not replace their wallet or custody model.
Fund Polymarket first
Add USDC (or supported methods) through Polymarket’s deposit flow. Your tradable balance may show as pUSD inside Polymarket after the upgrade.
Then use Polycopy
Follow traders, review the feed, and copy manually or with premium execution—same product workflow, independent of whether the label says USDC or pUSD under the hood.
We do not hold funds
Polycopy does not take custody of your trading balance. Risk controls and execution depend on your Polymarket account, wallet linking, and plan settings.

USDC.e vs pUSD (high level)
Both are ways to keep value pegged to the dollar on-chain; the shift is which token Polymarket uses inside its contracts to represent your collateral—not whether you are “betting in dollars.”
Polymarket previously relied on bridged USDC (often referred to as USDC.e on Polygon) for collateral. Bridge paths can add friction and edge cases when networks or approvals differ.
pUSD is described as Polymarket’s own 1:1 USDC-backed collateral token, settled with updated contracts as part of their exchange upgrade—aimed at reliability and clearer fee behavior. Details evolve; follow Polymarket’s official posts and docs for migration timing and one-click steps.
Polycopy is independent of Polymarket. We summarize public information to help our users; we are not the issuer of pUSD and do not control Polymarket’s contracts or fees.
Fees and minimums
Trading and deposit fees depend on Polymarket (and any third-party on-ramp you use). Polymarket documents fee schedules and deposit minimums in their help center—worth reading before your first transfer. Polycopy subscription pricing is separate; see Pricing.
Frequently asked questions
What is a stablecoin?
A stablecoin is a crypto token designed to track a stable reference—usually one U.S. dollar per token. Instead of prices swinging like Bitcoin or Ethereum, each unit is meant to stay near $1 so you can size trades, settle markets, and withdraw without constantly converting in and out of traditional bank rails. Common dollar stablecoins include USDC and USDT; venues like Polymarket pick one (here, USDC) as the economic unit of account, then may use an internal token (pUSD) to represent that value inside their contracts.
What is Polymarket USD (pUSD)?
pUSD is Polymarket’s USD-pegged collateral token on Polygon: a stablecoin-style balance inside the platform, backed 1:1 by USDC according to Polymarket’s public description. You deposit USDC; Polymarket represents your tradable collateral as pUSD for trading and settlement; you can swap back toward USDC when you withdraw. It is not meant to be a separate “investment” asset—you think in dollars, and pUSD is the plumbing that keeps those dollars consistent across trades and resolution.
Is pUSD the same as the POLY token?
No. pUSD is collateral for trading and settlement. A separate POLY governance token has been discussed publicly but is not the same product as pUSD. Always follow Polymarket’s official announcements for token launches and timelines.
How do I deposit or fund my Polymarket account?
Open Polymarket, use their deposit flow (card, bank where supported, or crypto transfer), and send supported assets on the correct network—typically USDC on Polygon for self-custody transfers. Polymarket’s help center has step-by-step deposit instructions. Polycopy does not hold your funds; you fund Polymarket first, then connect Polycopy for copy trading.
Does Polycopy hold my USDC or pUSD?
No. Your trading balance lives on Polymarket. Polycopy helps you discover traders and execute or mirror trades according to your plan and permissions. You still fund and withdraw through Polymarket.
Why did Polymarket introduce pUSD?
Polymarket describes pUSD as part of a broader exchange upgrade: native USDC-aligned settlement, updated contracts, and reliability improvements such as fewer failed trades and clearer fee handling at match time. Third-party reporting (e.g. CoinDesk) covers the announcement in more depth.
My deposit is not showing on Polymarket—what should I check?
Confirm you used the correct network (often Polygon for USDC), the asset Polymarket supports for that path, and that any required activation or bridge step completed. Use Polymarket’s official recovery or support resources if funds were sent on the wrong chain.
