Decentralized exchanges now account for roughly a quarter of all spot trading volume handled by their centralized counterparts. The DEX-to-CEX spot volume ratio hit 24.14% in July 2026, the highest level since tracking began in 2019.
Here’s the thing: this milestone arrived during what was actually a slow month for DEX trading. Absolute spot volume on decentralized platforms fell about 26% month-over-month to approximately $130.77B, marking its lowest point in nearly two years. DEXs are grabbing a bigger slice of a shrinking pie, which makes the ratio even more telling.
The numbers behind the shift
For most of 2024, DEX volume hovered below 10% of CEX volume. Then 2025 happened. The ratio started climbing steadily, reaching 13-14% and occasionally spiking as high as 25% during peak periods. July 2026’s 24.14% reading isn’t a one-off spike. It’s the continuation of a trend that’s been building for over a year.
Leading DEX protocols driving this volume include familiar names like Uniswap and PancakeSwap, alongside Aerodrome and newer entrants like Hyperliquid.
