Coinbase has reached a milestone that is instantly recognizable on Wall Street: it has become the only full-service prime brokerage in the cryptocurrency sector, as defined by the company itself. According to John D'Agostino, the head of strategy at Coinbase Institutional, the definition of a prime broker is still based on a familiar checklist used in traditional finance, which includes trading, custody, financing, derivatives, and cross-margining, with the added element of staking in the context of crypto. 'If you can perform all these functions at scale, you qualify as a prime broker,' he explained. In the 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. 'A hedge fund with $100 million in assets won't get everything from a top-tier firm; instead, they'll piece together services from various providers,' D'Agostino said.
'The major prime brokers offer the full suite of services.' The cryptocurrency market, until recently, operated in a similar manner, albeit with greater fragmentation. Funds would assemble services from multiple providers, with custody from one, derivatives from another, and financing from yet another. 'You can replicate a prime broker by combining services, but Coinbase is the only one doing all of it natively,' D'Agostino noted.
As the largest U.S.-based cryptocurrency exchange and a significant provider of infrastructure 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, which accounts for approximately 12% of the total cryptocurrency market capitalization, and serving as custodian for more than 80% of U.S. bitcoin and ether exchange-traded fund assets, Prime has established itself as a key player.
The firm has become a crucial bridge between traditional finance and cryptocurrency markets, serving as custodian for a significant portion of U.S. bitcoin and ether exchange-traded fund assets and operating under an expanding regulatory framework, including oversight from New York regulators. Crypto prime brokers provide institutional clients with a bundled suite of services designed to mirror traditional offerings in markets like equities and foreign exchange. These services help funds manage counterparty risk and access liquidity across fragmented venues.
Prominent players in this space include Coinbase Prime, Galaxy Digital, FalconX, and Anchorage Digital. The final component fell into place in March with the introduction of cross-margining between spot and derivatives positions, allowing market makers and institutional traders to reduce capital requirements by as much as 10% to 20%. 'That was the last piece of the puzzle,' D'Agostino said.
'Now we meet the standards of a prime broker, regardless of the asset class.' Coinbase's institutional platform processes approximately $236 billion in quarterly trading volume and supports over 470 assets across more than 20 blockchains. Beyond trading and custody, Coinbase operates a $1 billion lending book and what D'Agostino describes as the industry's largest listed derivatives footprint through its Deribit integration. The company's staking business spans 10 to 20 tokens at institutional scale, including dedicated products through Coinbase Asset Management. 'Those are the core components,' he said.
'There are firms that excel in custody, others in derivatives, and others in lending. No one is addressing all these issues in one place.' This gap has persisted partly due to the relatively small size of the cryptocurrency market, which accounts for roughly 3% to 5% of global equities and fixed income markets, making it too small for major banks to fully commit. D'Agostino expects banks and incumbents to partner instead. 'The options are to buy, build, or rent,' he said.
'Banks will opt to rent, as it's cheaper and smarter to partner with the best brand rather than building a mediocre version.' In the long term, this calculus could change if the cryptocurrency market grows to 20% or 30% of global markets. 'At that point, you'll see full-scale competition,' D'Agostino said.
'But that's years away.' For now, the greater threat comes from startups rather than traditional financial institutions. 'I'm less concerned about JPMorgan than I am about the next Brian Armstrong,' he added.
