GMX Review 2026: The Pool-Model Perp DEX Explained

Fees verified against GMX's official documentation on 2026-07-16; all other details verified 2026-07-17.

GMX is a decentralized perpetual exchange operating on Arbitrum and Avalanche. It has no order book. Instead of matching a buyer's order against a seller's order, every trade on GMX is filled directly against a liquidity pool, which acts as the counterparty. Understanding that one structural fact — pool as counterparty, not order-matching — explains almost everything else about how GMX behaves for traders and for liquidity providers.

What GMX Is: The Pool Model Explained

GMX's liquidity is organized into GM (GMX Market) pools. Each GM pool backs a single perp market and holds two assets: a long token and a short token, priced against an index price feed. The ETH/USD market, for example, pairs WETH as the long-side asset with USDC as the short-side asset. When a trader opens a long ETH position, the ETH/USD GM pool is the other side of that trade — its composition of WETH and USDC shifts to reflect the exposure it has taken on.

Sitting above individual GM pools are GLV (GMX Liquidity Vault) pools. A GLV pool is an automated vault that spans several supported GM markets at once, shifting liquidity between them according to utilization rather than requiring a depositor to pick a single market.

This is a fundamentally different design from an order-book perp DEX, where traders are matched against other traders and liquidity providers don't sit on the opposite side of every position by default. That contrast — and what it means for fees, slippage, and LP risk — is worth reading in full in our Hyperliquid vs. GMX comparison.

Trading Costs Summary

GMX charges a position fee on every open, close, increase, or partial decrease: 0.04% of position size when the trade reduces the long/short open-interest imbalance in a market, and 0.06% when it increases that imbalance. Separately, the side of the market with the larger open interest pays a borrow fee, calculated with a kink model that typically runs 45–55% annualized at the model's 75% utilization optimum. Trades also carry price impact, which is capped — on major markets, negative price impact is capped at 0.5%. Funding accrues continuously, per second, and can work as either a cost or a credit depending on which side of the market a position sits on. Full mechanics and current parameters are on our dedicated GMX fees page.

The LP Side: GM and GLV Pools

Liquidity providers are paid the majority of what GMX collects: 63% of protocol fees on both Arbitrum and Avalanche, sourced from trading fees, liquidations, borrow fees, and swap fees. That revenue flows directly into the value of the GM or GLV pool tokens an LP holds — there's no separate claim or harvest step.

The part worth stating plainly: the pool is the counterparty to every trade it backs. When traders as a group are profitable, that profit is paid out of pool value — it comes directly out of LP holdings. When traders as a group lose, that loss accrues to the pool, and LP value benefits. Providing liquidity to a GM or GLV pool is not a passive, market-neutral position; it is taking the other side of GMX's open interest. Withdrawal is also not always immediate — availability depends on how many of the pool's tokens are currently reserved against open positions. See our broader risk disclosure for how this compares to other DeFi liquidity models.

GMX Token

Staking GMX earns a share of protocol fees. Separately, a DAO-approved 27% of protocol fees is used to buy back GMX on the open market. Holding GMX also carries governance voting power over protocol parameters. One detail worth stating honestly rather than glossing over: per GMX's own documentation, distribution of the bought-back GMX to stakers is currently suspended. We're not covering token price or price targets here — that's outside what this page verifies.

Referral Program

GMX runs a tiered, on-chain referral program. At tier 1, traders who sign up through a referral code receive a 5% discount on trading fees, with the referrer earning a share in return. Tier structure and current rates are covered on our GMX referral page.

FAQ

Is GMX an order-book exchange?

No. GMX has no order book. Every trade fills against a GM or GLV liquidity pool, which acts as the direct counterparty to the trade.

What do liquidity providers earn on GMX?

LPs earn 63% of protocol fees on Arbitrum and Avalanche, flowing directly into the value of their pool tokens with no separate claim step. That return comes with real counterparty risk: the pool pays out trader profits from its own value, so LP returns are tied to how traders as a group perform against the pool.

Do I need KYC to use GMX?

In the wallet-connect flow we verified, there is no identity or KYC step. We have not verified GMX's geographic or jurisdictional access policy — check GMX's own terms before connecting a wallet.
