PHow to Buy Polymarket USD (PUSD)
Every exchange we track that lists PUSD, what the buy costs, and what it costs to take PUSD with you afterwards.
PUSD is thin on the ground: exactly one exchange we track lists it, Bitunix. With a single venue there is nothing to compare on price, so the thing worth checking is whether withdrawals are open before you buy. The cheapest place to place the order is Bitunix at $1.00 on a $1,000 market buy. Every exchange sends PUSD over Polygon, so there is no network to get wrong.

Where to buy PUSD
All-in cost is the trading fee on a $1,000 market buy plus the cheapest fee that exchange charges to withdraw PUSD. It is the number the exchange’s own “how to buy” page never shows you, and it reorders the table more often than not. The coins column is how many assets each exchange lists in total, from our own sync — not the figure CoinMarketCap prints.

Buying PUSD step by step
- Pick a venue from the table. For a coin this size the choice is usually short — 1 exchange lists PUSD at all, and the table already shows what you will pay to leave as well as to buy.
- Fund the account. 1 of those exchanges takes fiat, 0 of them by card. Card is fastest and dearest; a bank transfer costs a fraction of it. Depositing a stablecoin you already hold is free on almost every exchange here.
- Place the order. A market order pays the taker fee in the table; a limit order that rests on the book pays the lower maker fee. On a thinly traded coin the spread costs more than either, so a limit order is worth the wait.
- Decide whether to move it. Leaving PUSD on the exchange is free but custodial. Moving it to a wallet that supports it costs one withdrawal fee — send a small test amount first, and match the network on both sides.
How to buy PUSD — FAQ
Where can I buy Polymarket USD (PUSD)?
On 1 exchange we track: Bitunix. The table above has its trading fee, the payment methods it takes and what it charges to withdraw PUSD.
What is the cheapest way to buy PUSD?
We cannot rank the exchanges on cost for PUSD yet: the venues that list it have not published enough of their fee schedule for a like-for-like comparison. The withdrawal fees in the table are still exact.
Can I buy PUSD with a credit card?
None of the exchanges listing PUSD takes a card for it directly. The usual route is to buy USDT with a card on an exchange that does, withdraw it, and trade it for PUSD on one of the venues above. Budget for the card charge, the USDT withdrawal fee and the trade.
Do I have to pay a fee to withdraw PUSD?
Every exchange charges one, as a flat amount of PUSD per network rather than a percentage. We do not have a priced figure for all of the venues listing PUSD yet — the PUSD withdrawal fee page has whatever each exchange publishes.
Is it safe to leave PUSD on the exchange?
It is a custody choice, not a safety switch. While the coin sits there the exchange holds the keys: convenient, recoverable if you lose your password, and dependent on the exchange staying solvent and keeping withdrawals open. Moving it to a wallet you control removes that dependency and costs one withdrawal fee. For a trading balance, staying put is reasonable; for a long hold, most people move.
Exchange coverage for PUSD comes from each exchange’s own deposit and withdrawal endpoints (last sync 2026-08-29 00:53 UTC); trading fees are the published base tier, no volume discount applied (verified 2026-08-28). Exchanges we have a referral arrangement with appear first and are tagged as such — it changes no number in any row. Nothing here is investment advice; see our methodology.
