Is there a maximum bet?
No cap is documented. Polymarket's account limits are about speed and order count, not amount. What limits you is the other side of the trade: if your order is bigger than the resting orders near the current price, the rest fills at worse prices.
How deep the markets are
| Open market | Traded volume | Liquidity in the book |
|---|---|---|
| Will the U.S. invade Iran before 2027? | $80.2M | $0.47M |
| Will LeBron James win the 2028 US Presidential Election? | $55.2M | $2.21M |
| Will Oprah Winfrey win the 2028 Democratic nomination? | $54.7M | $2.73M |
Volume shows how much has traded over the market's life. Liquidity shows what is resting in the book now. A single market order far above the liquidity figure will move the price against you.

Fees at size: use limit orders
| Order type / category | Rate | Fee on a $1,000,000 stake at $0.50 |
|---|---|---|
| Limit order that rests (maker), any category | 0 | $0, plus a 15–25% maker rebate |
| Market order (taker), geopolitics | 0 | $0 |
| Market order (taker), politics, finance, tech | 0.04 | $20,000 |
| Market order (taker), sports, economics, general | 0.05 | $25,000 |
| Market order (taker), crypto | 0.07 | $35,000 |
The taker fee is shares × rate × price × (1 − price). On $1,000,000 at $0.50 that is 2% on politics and 3.5% on crypto. A resting limit order pays nothing and earns a rebate, so build size with limit orders in several tranches.
Moving a large amount in
- Deposit → Transfer Crypto; USDC is the simplest asset because trading collateral (pUSD) is backed by USDC.
- Send a small test first, confirm it is credited, then send the rest on the same network.
- If you buy USDC with AED, check the exchange's licence on the VARA public register.
Details: deposit from the UAE, AED to USDC and back.
Protecting a large balance
- Sign up with a wallet you control rather than a shared email.
- Never share the 6-digit login code: support says it cannot recover funds lost that way.
- Read the Withdrawal Allowlist article in the Polymarket Help Center before moving size out.
Cashing out
Withdraw from Portfolio → Withdraw: enter the address, token, amount and network, then confirm (Help Center, 12 Jan 2026). Polymarket charges no fee to withdraw USDC. Converting to AED happens at an exchange, outside Polymarket. Polymarket is not licensed by GCGRA, so treat it as a legal grey zone. Full route: withdrawals.
