What Is Polymarket USD (pUSD)?
pUSD is Polymarket’s dollar-pegged native trading collateral on the V2 order book—a stablecoin-style token backed by USDC—not a volatile crypto you trade for price swings. Below: what stablecoins are, how funding relates to USDC and pUSD, then 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 the collateral token for all trading on Polymarket: a standard ERC-20 on Polygon (6 decimals), backed by USDC with backing enforced by the contracts that enable withdrawals—not algorithmic or fractional reserve. Polymarket describes pUSD as an ERC-20 wrapper representing a USDC claim; CollateralOnramp and CollateralOfframp enforce wrapping and unwrapping on-chain (their docs walk through USDC.e → pUSD for the wrap path). Protocol trading settles against native USDC while you interact in pUSD; day to day you load funds, see a balance, trade, and withdraw—the same experience with pUSD 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 the in-platform ERC-20 collateral token; Polymarket documents wrapping from USDC.e via CollateralOnramp and unwrapping back through CollateralOfframp. Cross-chain deposits can auto-wrap to pUSD per their bridge docs. See Polymarket: Polymarket USD for contract-level detail.
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. On Polymarket, pUSD is the collateral token used for trading on the V2 CLOB: an ERC-20 on Polygon backed by USDC with backing enforced on-chain (not an algorithmic or fractional-reserve design—see Polymarket’s documentation). You typically fund via Polymarket’s flows; balances used for the order book are in pUSD.
What is Polymarket USD (pUSD)?
Per Polymarket’s documentation, pUSD (Polymarket USD) is the collateral token used for all trading—standard ERC-20 on Polygon (6 decimals), backed by USDC with the contracts enforcing backing (no algorithmic peg, no fractional reserve). It is a USDC claim wrapper: wrap and unwrap paths use on-chain CollateralOnramp and CollateralOfframp flows (e.g. USDC.e → pUSD for wrapping in their examples). The protocol describes settling trading activity against native USDC while you interact in pUSD day to day: load funds, see a balance, trade, withdraw. It is platform plumbing, not a separate investment asset. Official reference: docs.polymarket.com/concepts/pusd.
Is pUSD the same as the POLY token?
No. pUSD is collateral for trading and settlement. A separate governance token (often discussed as "POLY") has been mentioned publicly by the Polymarket team but has not launched as of April 2026. See our independent Polymarket token & airdrop tracker at https://polycopy.app/polymarket-token for everything that is verified vs speculated about a future token. 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 positions pUSD as part of moving to native USDC-aligned settlement and a more consistent collateral layer—alongside the V2 CLOB—with wrapping/unwrapping enforced on-chain for transparency. Their docs describe pUSD as capital-efficient infrastructure you mostly never think about. Third-party reporting (e.g. CoinDesk) covers the broader exchange upgrade 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.
