Perp DEX Open Interest Surges from 3.6% to 13.5% as Binance and OKX Still Dominate Centralized Market

CoinGecko's 2026 Crypto Perpetuals Report paints a market in structural transition: Binance and OKX still command 33% and 15% of perpetual futures market share respectively through the first four months of 2026, but the real story is happening at the edges.

Perp DEXs have grown their share of open interest from 3.6% at the start of 2025 to 13.5% — nearly a fourfold increase in roughly 16 months. That pace of share capture is the kind of trajectory that forces centralized venues to respond, either by improving UX and fee structures or by launching their own on-chain products.

BingX is the standout mover on the CEX side, with market share climbing more than 66% — from 3% to 5% — to rank seventh globally. It's a reminder that the mid-tier CEX race is far from settled, even as the top two incumbents hold their ground.
