Trading activity on decentralized perpetual exchanges has fallen to its lowest level of 2025, with monthly volume dropping to $355.78 billion in July, down sharply from a peak of $1.19 trillion in October. The decline suggests traders are gravitating back toward centralized platforms after a period of strong DEX momentum.
The broader perpetual futures market has also contracted, with combined volume across venues falling from roughly $1.65 trillion to $356.5 billion. Within that shrinking pie, decentralized exchanges are capturing a noticeably smaller slice than they were just months earlier.
CEXs Reclaim Market Share
The ratio of DEX-to-CEX futures volume has fallen to 11.49%, down from 21.6% in November, meaning centralized exchanges now account for roughly 96.03% of total derivatives trades. That marks a reversal from earlier in the cycle, when decentralized perpetual platforms were steadily closing the gap with their centralized counterparts.
The shift comes even as some decentralized venues continue to post strong numbers in specific niches. HIP-3 markets covering commodities and equities, for instance, hit a record open interest of $3.96 billion on July 30 before easing to $3.59 billion, with trading volume in the S&P 500 market alone reaching $741.04 million. Overall HIP-3 volume peaked near $9.19 billion on July 29 before cooling to roughly $6.99 billion by July 31.
A Cautious Broader Market
The pullback in DEX perpetual activity has coincided with softer sentiment across crypto markets more broadly. Bitcoin ETFs recorded a $265 million outflow on Friday alone, contributing to a weekly net outflow of $61.53 million for the period ending July 31, a sign that even traditional investment vehicles are seeing reduced risk appetite.
Taken together, the data points to a market where capital is consolidating around centralized venues for now, even as niche decentralized products built around commodities and equities continue to find pockets of demand. Whether the shift back toward CEXs proves durable or is simply a temporary pause in DEX growth remains an open question heading into the rest of the year.
