Fees
Backd charges a flat 1% of the stake on every order that fills. Polymarket collects it through the Builders Program; there is no Backd fee contract and nothing else to pay Backd.
What you pay
| Stake | Backd fee (1%) | Goes to the market |
|---|---|---|
| $5 | $0.05 | $4.95 |
| $10 | $0.10 | $9.90 |
| $50 | $0.50 | $49.50 |
| $100 | $1.00 | $99.00 |
| $500 | $5.00 | $495.00 |
When it's charged
- On a filled order to back a call, taken from the stake.
- On a filled order to sell early, taken from the proceeds.
- Not on orders that don't fill, on redemptions when a market settles, on deposits, or on withdrawals. Network costs on Polygon are a fraction of a cent and are covered.
What's free
Everything else: following, copying, crews, challenges, leaderboards, receipts, Wrapped, the API. Copying a call costs the same fee as any other call, because it is one.
Polymarket may charge its own fees on some markets (for example fast crypto rounds). Those are Polymarket's, shown in the call panel when they apply, and go to Polymarket, not Backd.
