GMX launched on Arbitrum in September 2021 and quickly became the most successful decentralized perpetual futures exchange before Hyperliquid’s rise. Created by a pseudonymous team led by “X,” GMX pioneered a model where liquidity providers earn real yield from trader losses — no token emissions needed.
The protocol’s GLP (GMX Liquidity Provider) pool was revolutionary. Instead of matching buyers and sellers, GLP acts as the counterparty to all trades. When traders lose money — and most do — those losses flow directly to GLP holders as real yield. During peak periods, GLP earned 30-50% APR from trader losses and fees alone.
This “traders lose, LPs win” model created a sustainable flywheel. Unlike other DeFi protocols that relied on inflationary token rewards, GMX’s yield came from genuine economic activity. The model proved so successful that dozens of “GMX forks” launched across multiple chains, creating an entire sub-category of DeFi.
GMX’s fee structure charges 0.1% to open and close positions, plus borrowing fees that vary with utilization. These fees — totaling hundreds of millions of dollars since launch — are split between GLP holders (70%) and GMX stakers (30%), creating demand for both tokens.
The V2 upgrade in 2023 introduced isolated markets with customizable parameters, allowing the protocol to list more volatile assets without endangering the entire liquidity pool. V2 also improved oracle design, reducing the manipulation vectors that had caused losses in V1.
Arbitrum became the natural home for GMX because of its low fees and fast confirmation times. The protocol accounted for a significant portion of Arbitrum’s total TVL and was the primary reason many users bridged to the L2. GMX’s success on Arbitrum demonstrated that “killer apps” drive L2 adoption more than technology alone.
By 2024, Hyperliquid had overtaken GMX in volume with its orderbook model. But GMX’s pool-based approach remained attractive for passive LPs who wanted DeFi yield without actively managing positions. The two models coexist, serving different user segments in the decentralized derivatives market.
