Note: Trading fees on Outcome are currently set to zero while HIP-4 is in testing. This page describes the fee structure that will apply after testing concludes.
When you pay
Opening. No fee. Opening trades don’t count toward your 14-day volume.
Closing. When you sell your tokens back, the fee depends on which side of the trade you’re on. Maker orders (those that rest on the book until matched) pay zero. Taker orders (those that match an existing order immediately) pay the standard taker fee.
Settlement. When the market resolves and your position settles automatically, a settlement fee is deducted from the payout.
Discounts
Outcome trading uses Hyperliquid’s protocol-wide fee tiers. Your taker rate decreases as your trailing 14-day volume across all Hyperliquid products grows and as your linked HYPE stake increases.
Because USDH is the quote currency for outcome markets, taker fees are 20% lower than the standard rate, and outcome volume counts 20% more toward your Hyperliquid fee tier.
Maker rebates
Outcome markets do not pay maker rebates. Maker orders pay zero fees, but unlike perpetuals or spot, they don’t earn a rebate either.
Bridging fees
When you deposit from another chain through Outcome’s built-in bridge, an Across bridging fee applies. This fee is set by Across and is separate from Outcome and Hyperliquid trading fees. The amount is shown in the deposit interface before you confirm the transfer.
For exact rates
The full fee schedule, including tier breakpoints, the USDH discount, and the settlement fee, is on Hyperliquid’s fees page.
