Fee Schedule
Polyburg charges two things: a flat membership, and a per-share fee on trades. There is no performance fee, no AUM fee, and nothing on deposits, withdrawals or winning claims. Every figure below is shown in-app before you confirm.
Membership
$10/month billed yearly ($120), or $30 month-to-month. One flat fee unlocks trading, copy rules and Presets. Your first month is free with an invite from an existing member.
Membership gates entering positions only. Selling, exiting a Preset, withdrawing funds and claiming winnings are never locked behind it — if you let membership lapse, your money and positions remain fully yours to close out.
Per-Trade Fee
Every buy and sell pays the same per-share fee — whether you traded manually, a Copy Rule fired, or a Preset traded on your behalf. It is charged per share, not per dollar, so favourites are the cheapest trades and long shots carry a higher rate against a far larger payoff.
p = fill price (between 0 and 1)
fee_per_share = 0.056 × p × (1 − p), minimum $0.0024
# Charged on each leg, priced off its own fill.
# As a share of your stake: ~0.3% on heavy favourites,
# rising as the potential payout rises.
Worked Examples
| Fill price | If it settles your way | Polyburg fee | Notes |
|---|---|---|---|
| $0.95 | +5% | 0.28% | Heavy favourite — the cheapest trade on Polyburg. |
| $0.75 | +33% | 1.40% | |
| $0.50 | +100% | 2.80% | |
| $0.25 | +300% | 4.20% | |
| $0.05 | +1,900% | 5.32% | Long shot — ~0.3% of the payout you are chasing. |
If someone referred you, their reward comes out of Polyburg's cut — you pay exactly the same either way.
Presets
Investing in a Preset and adding to it are free of any extra Polyburg charge — your copied trades pay the standard per-share fee above. Exiting a Preset carries a 0.2% exit fee on the amount coming back, covering the cost of liquidating your slice across every open position.
What Polymarket Charges Separately
Polymarket applies its own fee when an order fills. It goes to Polymarket, not Polyburg, and stacks on top of ours. Their headline rate depends on the market category (0% on geopolitics up to 7% on crypto) and is scaled by fill price — highest near 50¢, falling toward the extremes. The exact figures live in Polymarket's fee docs.
What You Don't Pay For
- •Winning claims and redemptions: no fee — settled payouts arrive whole.
- •Deposits: no Polyburg fee. The bridge converting your incoming token may take a small conversion cut, shown before you confirm.
- •Withdrawals: no Polyburg fee — we cover the Polygon network cost, so you never need to hold POL.
- •Performance: we never take a percentage of your profits or your balance.
