Polymarket guide
How to deposit on Polymarket
Polymarket runs on crypto: you fund with USDC, a dollar-pegged stablecoin, on the Polygon network. There are a few more steps than a dollar platform, but once you’re set up it’s quick. Here’s the path.
The key thing to understand is that Polymarket uses self-custody — your funds stay in a crypto wallet you control rather than in a platform account. That’s a feature for crypto users, and the main hurdle for everyone else. If this is your first time with a wallet, our Polymarket review sets the context, and a dollar-funded option like Kalshi is a gentler starting point.
Set up or connect a crypto wallet
You’ll need a compatible crypto wallet. Polymarket guides you through connecting one during onboarding, including options that make wallet creation straightforward for newcomers.
Get some USDC
USDC is a stablecoin designed to hold a value of one US dollar. You can buy it on a crypto exchange or through an on-ramp service, then move it to your wallet. Acquire a little more than you plan to trade to cover small network fees.
Make sure your USDC is on Polygon
Polymarket operates on the Polygon network, so your USDC needs to be on Polygon (not another chain). If it’s elsewhere, bridge it across — many wallets and exchanges support this directly. This step trips up first-timers, so double-check the network.
Deposit into Polymarket
With USDC in your wallet on Polygon, connect the wallet to Polymarket and deposit. Your balance becomes available to trade.

Sending USDC on the wrong network is the most common mistake. Always confirm both the token (USDC) and the network (Polygon) before sending.
