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 its own definition. John D'Agostino, the head of strategy at Coinbase Institutional, explained that the traditional definition of a prime broker encompasses trading, custody, financing, derivatives, and cross-margining, with staking being an additional layer in the crypto space. 'If you can provide all of these services at scale, then you're a prime broker,' he stated.
In the equities and fixed income markets, only a select few firms, including Goldman Sachs, Morgan Stanley, and Bank of America, qualify as full-service prime brokers. Smaller brokers may support funds but lack the comprehensive range of services. 'A $100 million hedge fund won't receive the full suite of services from a top-tier firm; instead, they'll have to piece it together,' D'Agostino said.
'The major prime brokers offer everything.' The cryptocurrency sector, until recently, operated in a similar manner but was more fragmented. Funds had to combine custody services from one provider, derivatives from another, and financing from yet another. 'You can artificially replicate a prime broker by stitching together various services,' D'Agostino said.
'However, Coinbase is the only firm that provides all of these services natively.' As the largest U.S.-based cryptocurrency exchange and a key 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. Prime holds over $350 billion in assets under custody, accounting for approximately 12% of the total cryptocurrency market capitalization, and serves as custodian for more than 80% of U.S. bitcoin and ether ETF assets.
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 ETF 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. They 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 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,' D'Agostino said. 'Now we're a prime broker by any standard, regardless of the asset class.' Coinbase's institutional platform 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 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. 'Those are the core components,' he said.
'There are firms that excel in custody, others in derivatives, and others in lending. However, no one is addressing all of these issues in a single location.' This gap has persisted in part 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. 'Buy, build, or rent,' he said.
'Banks will opt to rent, as it's more cost-effective and smarter to rent the best brand rather than build a mediocre version.' In the long term, this calculation 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.
'However, that's years away.' For now, the bigger threat isn't Wall Street, but rather startups. 'I'm less concerned about JPMorgan than I am about the next Brian Armstrong,' he added.
