Coinbase has achieved a milestone that is instantly recognizable on Wall Street: it has become the only full-service prime brokerage in the cryptocurrency sector. According to John D'Agostino, head of strategy at Coinbase Institutional, the definition of a prime broker involves a specific set of services, including trading, custody, financing, derivatives, and cross-margining, with an additional layer of staking in the context of crypto.
D'Agostino emphasized that if a company can provide all these services at scale, it qualifies as a prime broker. In traditional equities and fixed-income markets, only a select few firms, such as Goldman Sachs, Morgan Stanley, and Bank of America, meet the criteria for full-service prime brokers. Smaller brokers may support funds but lack the comprehensive range of services.
In the crypto space, until recently, the landscape was similarly fragmented, with funds patching together services from various providers. However, Coinbase is distinct in that it natively offers the full suite of services. As the largest U.S.-based cryptocurrency exchange and a major infrastructure provider for institutional investors, Coinbase offers trading, custody, and financing services through its Coinbase Institutional unit. The flagship platform, Coinbase Prime, integrates these functions into a single system, enabling hedge funds and asset managers to trade, store, and finance digital assets under one roof.
With over $350 billion in assets under custody, representing about 12% of the total crypto market capitalization, and serving as custodian for more than 80% of U.S. bitcoin and ether ETF assets, Coinbase Prime has become a pivotal bridge between traditional finance and crypto markets. The firm operates under a growing regulatory framework, including oversight from New York regulators. Crypto prime brokers like Coinbase Prime provide institutional clients with a bundled suite of services that mirror traditional offerings in markets like equities and FX, helping funds manage counterparty risk and access liquidity across fragmented venues.
The rollout of cross-margining between spot and derivatives positions in March marked the final piece of the puzzle, allowing market makers and institutional traders to reduce capital requirements by as much as 10% to 20%. This development has positioned Coinbase as a prime broker by any standard, with D'Agostino noting that the company can now substitute crypto for any asset class. The institutional platform processes roughly $236 billion in quarterly trading volume and supports more than 470 assets across 20-plus blockchains. Beyond trading and custody, Coinbase has a $1 billion lending book and what D'Agostino describes as the industry's largest listed derivatives footprint through its Deribit integration.
Its staking business spans 10 to 20 tokens at institutional scale, including dedicated products through Coinbase Asset Management. According to D'Agostino, while other firms excel in specific areas like custody, derivatives, or lending, none solve all these problems in one place. This gap persists partly due to crypto's relatively small size, at roughly 3% to 5% of global equities and fixed-income markets, making it too small for major banks to fully commit. Instead, D'Agostino expects banks and incumbents to partner, adopting a 'buy, build, or rent' approach, with renting being the cheaper and smarter option.
However, if crypto grows to 20% or 30% of global markets, the calculus could change, leading to full-scale competition. For now, the bigger threat to Coinbase comes from startups rather than established Wall Street players.
