Crypto custodians, once dismissed as boring infrastructure providers, are now central to Wall Street's transformation. These firms, which secure more than $500 billion in digital assets, are rapidly expanding beyond their traditional role of simply keeping crypto safe. They are now offering trading services, stablecoin issuance, derivatives, settlement networks, and AI infrastructure to banks and asset managers seeking digital-asset exposure without building the machinery themselves.

Why Are Custodians Suddenly So Powerful?

The shift began with a simple problem. When Bitcoin launched, there was no safe way for institutions to hold it. Mike Belshe, cofounder and CEO of BitGo, the first dedicated crypto custodian, explained the original challenge: "I never wanted to build a custody service. It's just something we had to do because nobody else had built it." BitGo's innovation was multisig technology, short for multi-signature, which requires more than one key to approve a transaction, dramatically reducing the risk of theft or insider fraud.

That simple security solution attracted a tidal wave of institutional interest. Today, BitGo secures more than $80 billion in crypto for approximately 5,500 clients across dozens of blockchains. The company went public in January 2026 through a $2.6 billion initial public offering (IPO), becoming the first publicly traded crypto custodian.

But custody itself is not a high-margin business. Clients typically pay 20 basis points, or two-tenths of a penny, for each dollar of crypto they store. However, those tiny fractions add up significantly. BitGo's revenues reached $16.2 billion in 2025, up nearly 425 percent from 2024.

How Are Custodians Expanding Their Business Beyond Safekeeping?

Recognizing that pure custody offers limited profit margins, the largest custodians are moving aggressively up the value chain. They are adding services that generate wider margins and deeper relationships with institutional clients:

• Trading Services: BitGo now offers institutional clients access to multiple exchanges, including OKX and Deribit, without requiring them to move assets out of custody. This broker-style model seeks the best prices across venues, a significant advantage over single-exchange trading.
• Stablecoin Infrastructure: Anchorage Digital, which holds $56 billion in digital assets, has partnerships with roughly 20 stablecoin issuers, including Tether, Ethena, and Western Union. BitGo's stablecoin-as-a-service business generated $66.7 million from clients including World Liberty Financial and SoFi.
• Derivatives and Settlement Networks: BitGo added derivatives trading in the first quarter of 2026, generating roughly $3 billion in notional trading volume. Anchorage expanded its Atlas settlement and collateral-management network fourfold to nearly 600 institutions.
• AI and Agentic Banking: In May 2026, Anchorage added agentic banking capabilities, allowing enterprises to fund and control artificial intelligence agents that operate on their behalf.

Nathan McCauley, cofounder and CEO of Anchorage Digital, one of the four largest crypto custodians, emphasized the scope of this transformation: "Custody is almost a misnomer at this point for this category." Anchorage became the first federally chartered crypto bank in 2021 and now serves more than 1,000 institutional clients. The company has doubled revenue every year for the past three years, with derivatives and stablecoin issuance as its fastest-growing businesses.

What Is Driving This Institutional Shift?

The move toward on-chain financial infrastructure is being driven by concrete economic incentives. Over the past decade, failed trades and delayed clearing have cost the financial industry an estimated nearly $1 trillion. When the United States reduced equity settlement from two business days to one, the clearing fund at the Depository Trust and Clearing Corporation (DTCC) dropped $3 billion in just three months, freeing up trapped capital immediately.

Global stablecoin transaction values reached $33 trillion in 2025, signaling massive institutional adoption. This shift is accelerating because tokenized assets generate structured, immutable transaction data that traditional financial networks cannot provide. When trading algorithms operate in milliseconds, waiting two business days for a trade to settle creates mispriced collateral and counterparty risks. Moving to on-chain settlement reduces these inefficiencies while generating the clean data required to train advanced artificial intelligence models.

Regulatory clarity has also catalyzed adoption. The passage of the GENIUS Act in July 2025 established a federal regulatory framework for stablecoins. The impact was immediate: over 1,500 U.S. banks integrated stablecoin capabilities into their operations. Visa and Mastercard began supporting USDC settlement directly on their card-payment networks. A consortium including Citi and Wells Fargo started exploring a joint stablecoin initiative to facilitate instant cross-border transfers.

"Once the GENIUS Act passes, every single bank in the country is going to want to partner with a crypto bank, with us, in order to enable its crypto offerings," said Nathan McCauley.

Major financial institutions are now moving beyond pilot programs. JPMorgan recently introduced a tokenized money market fund on Ethereum, allowing qualified investors to access U.S. dollar yields while holding tokens directly in their registered wallets. Nasdaq secured Securities and Exchange Commission (SEC) approval to permit the tokenized trading of highly liquid securities, including Russell 1000 equities and major exchange-traded funds (ETFs).

What Does This Mean for the Future of Finance?

The scale of this transformation is staggering. Grand View Research estimates that the global digital-asset custody market was $683 billion in 2024 and projects it will reach $4.4 trillion by 2033. Multiple forecasters project the tokenized asset market will reach between $2 trillion and $16 trillion by 2030, depending on adoption rates.

Despite near-term headwinds, custodians are positioning themselves as the essential infrastructure layer for this transition. BitGo's stock has declined 65 percent from its IPO price of $18 to $6.35, partly due to bitcoin's price decline from $90,000 to $65,000, which reduced asset-based revenues. However, Belshe remains confident in the company's growth trajectory, pointing to trading as the next major expansion opportunity.

The real value, according to industry observers, lies not just in custody fees but in the data and relationships custodians control. Institutions that properly structure tokenized transaction data can package automated audit trails into regulatory technology products, transforming compliance from a cost center into a revenue-generating service. As more traditional banks recognize the cost and complexity of building their own crypto infrastructure, they will increasingly turn to custodians as partners, making these firms central to the future of financial plumbing.
