# Trading Fees

PredictEX operates on a trading fee model based on notional trading volume. This means that fees are calculated based on the total value of the positions taken by users, similar to traditional exchanges. There are two types of trading fees, which are used to finance the platform's operations.

#### Platform fee

The Platform Fee is a flat fee of 0.2% on notional trading volume and remains constant across all phases of protocol operation. This fee funds the ongoing operational costs of the PredictEX platform.

#### Platform Stability Adjustment

The Platform Stability Adjustment is a dynamic fee charged only on leveraged positions (Boost greater than 1x). Its size depends on the contract's current price, selected leverage, time remaining, score, league, and other market conditions — the more uncertain the outcome, the higher the adjustment.

This fee compensates for the structural risk of offering leverage on binary contracts, where prices can jump discontinuously at settlement or on new information. Proceeds flow back into the liquidity pool to absorb the volatility leveraged positions introduce, keeping the platform solvent across all market conditions.

The adjustment is partly charged upfront when a leveraged position is opened and is built into the Max Payout shown before you place a bet — it is not displayed as a separate line item. Because some of this adjustment is taken at entry, your cash-out value can potentially start  below your cost basis; your Max Payout already accounts for it. \[[Learn more →](/docs/risk-management.md)]
