Liquidation mechanics on Polymarket Perps
Polymarket Perps uses an isolated margin model by default for perpetual futures. When your equity in an isolated position falls below the maintenance margin requirement, Polymarket Perps's risk engine triggers liquidation, forcibly closing the position to prevent a negative balance.
The maintenance margin rate on Polymarket Perps is typically 0.5% for major pairs (BTC, ETH). For a long position, liquidation price ≈ entryPrice × (1 − 1/leverage + 0.005). At 20× maximum leverage this means even a tiny adverse move can trigger liquidation, which is why most experienced traders use 5–20× rather than the maximum.
Polymarket Perps also has an "auto-deleveraging" (ADL) system for extreme scenarios where the insurance fund is insufficient. In practice, staying well above your liquidation price eliminates ADL risk entirely.
Polymarket Perps fee structure
Polymarket Perps charges maker fee 0.0125% and taker fee 0.04% on perpetual futures. Maximum available leverage is 20×. This calculator pre-fills these defaults so you get accurate results without needing to look up the fee schedule. If you are on a VIP tier with discounted fees, adjust the fee fields accordingly.
Maker orders (limit orders that add liquidity) cost less than taker orders (market orders that remove liquidity). On Polymarket Perps, using limit orders for both entry and exit can reduce your total fee cost significantly compared to market orders.
