Coinbase has achieved a milestone that is instantly recognizable on Wall Street: it has become, in its own words, the only full-service prime broker in the cryptocurrency space. According to John D'Agostino, the head of strategy at Coinbase Institutional, a prime broker is defined by its ability to provide trading, custody, financing, derivatives, and cross-margining services. In the context of crypto, staking is an additional crucial component.
'If you can deliver all of these services at scale, then you qualify as a prime broker,' he explained. In the traditional equities and fixed-income markets, only a select few firms, including Goldman Sachs, Morgan Stanley, and Bank of America, meet the criteria for full-service prime brokers.
Smaller brokerage firms may support funds, but they lack the comprehensive suite of services. 'A hedge fund with $100 million in assets won't receive full-service treatment from a top-tier firm; instead, they'll have to piece together services from various providers,' D'Agostino noted.
'The major prime brokers, on the other hand, offer the complete package.' The cryptocurrency market, until recently, operated in a similar manner, albeit with greater fragmentation. Funds would typically obtain custody services from one provider, derivatives from another, and financing from yet another source. 'You can replicate the services of a prime broker by combining different providers, but Coinbase is the only one that offers all of these services natively,' D'Agostino said. 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 division.
The flagship platform, Coinbase Prime, integrates these functions into a single system, allowing hedge funds and asset managers to trade, store, and finance digital assets under one roof. With over $350 billion in assets under custody, representing approximately 12% of the total cryptocurrency market capitalization, Prime serves as the custodian for more than 80% of U.S. bitcoin and ether exchange-traded fund assets.
The firm has established itself as a vital bridge between traditional finance and cryptocurrency markets, serving as the custodian for a substantial portion of U.S. bitcoin and ether exchange-traded fund assets, and operating under an expanding regulatory framework that includes oversight from New York regulators. Crypto prime brokers provide institutional clients with a bundled suite of services designed to mirror traditional offerings in markets such as equities and foreign exchange.
These services enable funds to 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 piece of the puzzle 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 component we needed to become a full-service prime broker,' D'Agostino said.
'Now, by any standard, we qualify as a prime broker, regardless of the asset class.' The institutional platform of Coinbase processes approximately $236 billion in quarterly trading volume and supports more than 470 assets across over 20 blockchains. Beyond trading and custody, Coinbase operates a $1 billion lending book and boasts the largest listed derivatives footprint in the industry through its integration with Deribit.
The company's staking business spans 10 to 20 tokens at institutional scale, including dedicated products offered through Coinbase Asset Management. 'Those are the core components of a prime broker,' D'Agostino said. 'There are firms that excel in custody, others in derivatives, and others in lending, but no one else is providing all of these services in one place.' This gap in the market has persisted in part due to the relatively small size of the cryptocurrency market, which accounts for only 3% to 5% of the global equities and fixed-income markets, making it too small for major banks to fully commit.
D'Agostino anticipates that banks and established players will instead opt to partner with existing firms. 'The options are to buy, build, or rent,' he said. 'Banks will choose to rent, as it is more cost-effective and smarter to partner with the best brand rather than building a mediocre version.' However, this calculus could change if the cryptocurrency market grows to 20% or 30% of the global market, at which point full-scale competition is likely to emerge. 'But that's years away,' D'Agostino said.
For now, the more significant threat to Coinbase comes not from Wall Street, but from startups. 'I'm less concerned about JPMorgan than I am about the next Brian Armstrong,' he added.
