Custodians consolidate $152.9B custody

CoinGlass’s Q1 2026 exchange report found Binance held an average $152.9 billion in user assets, far more than any other centralized crypto venue. (coinglass.com) That figure represented about 73.5% of user asset reserves tracked across major centralized exchanges in the quarter. CoinGlass said OKX, the second-ranked venue by reserves, was at roughly $15.9 billion. (coinglass.com) The same report showed Binance leading on trading activity too, with about $4.90 trillion in derivatives volume in Q1 and an average daily open interest of $23.9 billion. (coinglass.com) Custody in crypto means an exchange is holding customer coins and collateral. When more of that money sits on one platform, operational trouble at that platform can hit more traders at once. (coinglass.com) (binance.com) Q1 was a cooling quarter for the broader exchange market. TokenInsight said total exchange trading volume fell 32% quarter over quarter to $17.9 trillion, with both spot and derivatives volumes hitting multi-quarter lows. (tokeninsight.com) Even in that slowdown, derivatives remained the center of activity. CoinGlass put Q1 spot volume at about $1.94 trillion versus $18.63 trillion in derivatives, a ratio of roughly 9.6 to 1. (coinglass.com) TokenInsight described the quarter as a “structural recalibration,” with the top five exchanges controlling 72.17% of total volume. In derivatives alone, Binance, OKX and Bybit accounted for about 59% of volume. (tokeninsight.com) That helps explain why the $152.9 billion number matters: it was not a market-wide custody total, but Binance’s average daily reserve balance inside a market that was already concentrating around a few large venues. (coinglass.com) (tokeninsight.com) Large exchanges argue that scale supports liquidity, hedging and deeper collateral pools. Binance’s April proof-of-reserves update said key assets including Bitcoin, Ether and Tether remained backed above 100% of user balances. (binance.com) But concentration also leaves more of the market exposed to one venue’s maintenance windows or service interruptions. Binance’s support page shows repeated wallet maintenance notices across major networks in April 2026 alone. (binance.com) The quarter’s headline, then, is less “crypto custody hit $152.9 billion” than “Binance did.” In Q1 2026, the market shrank, derivatives dominated, and more customer assets stayed in one place.
