Overdog charges a small fee on each trade to cover the service. All fees are taken from your trade amount before the order is sent to the market.
Fee schedule
| Fee type | Rate | When charged |
|---|
| Trading fee | 1% | Every buy and every sell |
| Copy trading fee | 0.5% | Every trade executed via copy trading |
| Withdrawal (same chain) | $0 | Polygon USDC withdrawal |
| Withdrawal (cross-chain) | Network gas (varies) | Tron and Solana withdrawals |
Polymarket itself does not charge additional fees for market orders. The Overdog trading fee covers the full cost of the service — there are no hidden charges on top.
How the trading fee is applied
The fee is deducted from your input amount before the order is placed. You always see the exact net amount in the confirmation screen before you confirm.
Buy example
| Amount |
|---|
| You enter | $100.00 |
| Overdog fee (1%) | −$1.00 |
| Net invested | $99.00 |
| Amount |
|---|
| Shares sold at $0.50 each → gross proceeds | $50.00 |
| Overdog fee (1%) | −$0.50 |
| You receive | $49.50 |
Copy trading fee
When you copy another trader, each mirrored trade is charged at 0.5% — half the standard rate. The fee is applied the same way: deducted from the trade amount before execution.
Withdrawal fees
Withdrawals to Polygon USDC are free — no bridge or gas fee is charged.
Withdrawals to other networks go through a bridge and are subject to network gas costs:
- Tron USDT (TRC-20) — bridge fee typically around 3.5 USDT, deducted from the amount you receive.
- Solana USDC — bridge fee varies with network conditions.
You will always see an estimated fee and the amount you will receive on the confirmation screen before you type CONFIRM. If a quote cannot be fetched, the withdrawal will not proceed until an estimate is available.
