01.Free the capital first
Open positions are contracts, not cash. To get money out you either sell the position into the order book at the current price, or wait for the market to resolve and redeem the winning contracts. Selling is immediate but subject to whatever depth exists; waiting is certain but ties up capital until the event settles.
- Sell into the book for immediate liquidity, at whatever price depth allows.
- Or hold to resolution, where winners redeem at a dollar and losers at nothing.
- On thin markets, selling a large position can cost more than the wait would have.
02.Sending it out
Once the USDC is unencumbered, moving it is an ordinary transfer from your wallet. The two things to get right are the same as on the way in: the destination address and the network. If you are sending to an exchange, confirm that exchange accepts USDC on Polygon before you send anything.
- Confirm the receiving exchange supports USDC on the network you are sending from.
- Send a small test first when using a destination for the first time.
- You need a little gas token to send, same as any other transaction.
03.Nobody can stop you
This is the structural difference from a brokerage or a sportsbook. Because no operator holds the funds, no operator can delay a withdrawal, impose a verification hold, or close your account with a balance in it. That protection is the same design that makes losing your key unrecoverable — you cannot have one without the other.
- No withdrawal approvals, holds, or account closures with funds inside.
- The same design means no recovery if you lose access.
- Consistent winners cannot be limited, which is not true of bookmakers.
04.Cashing out to fiat
Converting USDC to your bank currency happens off Polymarket entirely, through an exchange or on-ramp service that supports it. That step is where identity verification and conventional banking rules apply, and where the requirements vary by where you live — check your chosen provider directly rather than assuming.
- The USDC-to-fiat step happens on an exchange, not on Polymarket.
- Identity verification applies at that stage, not before.
- Requirements and availability vary by jurisdiction and provider.
