Coinbase has achieved a milestone in the crypto space by becoming the only full-service prime broker, offering a comprehensive suite of services including trading, custody, financing, derivatives, and cross-margining. According to John D'Agostino, head of strategy at Coinbase Institutional, this combination of services is what defines a prime broker in traditional finance. In the crypto industry, an additional layer of staking is also required.

D'Agostino noted that only a handful of firms in equities and fixed income, such as Goldman Sachs and Morgan Stanley, qualify as full-service prime brokers, and that smaller brokers often lack the full range of services. In crypto, until recently, funds had to piece together services from multiple providers, but Coinbase is now the only platform to offer all of these services natively. The company's flagship platform, Coinbase Prime, bundles 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 and serving as custodian for more than 80% of U.S. bitcoin and ether ETF assets, Coinbase has become a key bridge between traditional finance and crypto markets. The firm has also become a significant player in the crypto prime brokerage space, alongside other prominent players such as Galaxy Digital, FalconX, and Anchorage Digital.

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. Coinbase's 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 also runs a $1 billion lending book and has the industry's largest listed derivatives footprint through its Deribit integration. D'Agostino expects that banks and incumbents will partner with Coinbase rather than trying to build their own crypto prime brokerage capabilities, at least in the near term. However, he notes that the bigger threat to Coinbase's position is likely to come from startups rather than established players.
