GMX fees & measured trading cost
GMX does not use a conventional order book: it settles futures trades against an oracle price. FeeFloor therefore doesn’t calculate order-book spread or slippage for it and reports the protocol cost components its current model supports. FeeFloor measures GMX's futures market on BTC, ETH, SOL and XRP, live against every venue we track, and a $100K BTC futures order currently reports $54.00 in those components. Funding, borrowing, price-impact and withdrawal costs sit outside that figure and aren’t included here.

Not calculated — this venue settles against an oracle, not an order book, so FeeFloor doesn’t compute book slippage here. Any price-impact term is part of the protocol model, not shown as slippage.
What our measurements show
GMX's rank moves with trade size: #3 of 49 at $10M, but #35 at $10K. Fees are flat — depth is not.
At $100K, GMX runs 12% above the median venue we track (5.40 bps vs 4.81 bps).
Pricing comes from an oracle rather than an order book, so FeeFloor reports the 5.40 bps protocol fee and doesn't compute book spread or slippage — the order-book components other venues carry don't apply here. Funding, borrowing and any price-impact terms are separate.
Signing up through our link takes 10% off the fee component — the discount is applied in every number above, and the struck-through figures show list price.
Cost by trade size
Fees are flat, but spread and slippage scale with size — so a venue that wins at $10K can be mid-pack at $10M. BTC futures, taker.

GMX: quick answers
What does a $100K BTC trade actually cost on GMX?
As of 2 August 2026, a $100K BTC futures market order on GMX costs $54.00 all-in (5.40 bps): 5.40 bps fee, 0.00 bps spread and 0.00 bps slippage. That ranks #29 of 49 venues we measure.
Is GMX better for small or large orders?
Right now, large orders: GMX ranks #35 at $10K and #3 at $10M. Fees are flat percentages, but slippage grows with size, so the answer shifts with the venue's live order-book depth.
Does GMX have hidden costs beyond the trading fee?
GMX does not use a conventional order book — it settles against an oracle price. FeeFloor therefore does not calculate order-book spread or slippage for it and reports the protocol cost components its current model exposes. Funding, borrowing, price-impact and withdrawal costs sit outside that figure.

How FeeFloor measures GMX
FeeFloor measures GMX on its futures market for BTC, ETH, SOL and XRP, pricing from an oracle (no conventional order book).
Because GMX settles against an oracle rather than a conventional order book, FeeFloor does not calculate order-book spread or slippage for it and reports the protocol cost components its current model exposes. Funding, borrowing, price-impact and withdrawal costs sit outside that figure.
Regulatory assessment is outside FeeFloor’s scope: we measure execution cost, not whether GMXis legally available to a given user. Legal-entity and regulatory data are not independently verified by us — see Sources & verification below.
