How Does a Market Maker Estimate the Future Slippage Cost for a Hedge?

Market makers estimate future slippage cost by analyzing historical market data, specifically the depth and elasticity of the order book for the underlying asset. They use models that factor in the expected size of the hedge (derived from the option's Delta and the RFQ size) and the asset's typical market impact profile to project the likely execution price difference.
