Quick Take
  • Wall Street’s crypto footprint has never been larger.
  • BlackRock alone reported nearly $150 billion in digital asset-linked AUM in its 2026 chairman’s letter.
  • Public companies hold over 1.1 million BTC on their balance sheets.
  • Institutions disclose more than 513,000 BTC through ETF wrappers.

What Happened

Despite a 23% price decline in Q4 2025, global Bitcoin ETF flows remained positive at $3.7 billion. Full-year professional ETF ownership grew 32% versus 18% for the broader ETF investor base.

Market Context

It starts with SEC 13F filings, moves through corporate balance sheets, follows the money into tokenized fund rails, traces the custodial chokepoints where keys concentrate, and ends where filings go dark, with on-chain OTC flows that reveal holders no quarterly report captures.

Not all of this is conviction capital. The basis trade, a strategy involving a long spot ETF position paired with a short CME futures position, has been a primary institutional strategy since ETF approval.

Cohort rotation, not capitulation, defined Q4. Millennium added 8,100 BTC. Abu Dhabi’s Mubadala added 2,300 BTC. Morgan Stanley added 1,900 BTC. Dartmouth became the fourth Ivy League endowment to enter.

The concentration is extreme. Strategy Inc, formerly MicroStrategy, held 762,000 BTC as of April 2, 2026. Other big names in the space include Twenty One Capital, MARA Holdings, Japan’s Metaplanet, and more.

BlackRock’s BUIDL fund, a tokenized US Treasury money market product, reached $2.85 billion in total assets ($2.17 billion at press time).

In February 2026, BlackRock began trading BUIDL on Uniswap’s decentralized exchange and purchased UNI governance tokens. That marked its first direct engagement with DeFi trading infrastructure.

The broader market is scaling fast. RWA.xyz data as of April 2026 shows $12.67 billion in on-chain US Treasury debt, representing roughly 46% of the total $27.59 billion in tokenized real-world assets.

Why It Matters

Wall Street’s crypto footprint has never been larger. BlackRock alone reported nearly $150 billion in digital asset-linked AUM in its 2026 chairman’s letter. Public companies hold over 1.1 million BTC on their balance sheets. Institutions disclose more than 513,000 BTC through ETF wrappers.

Yet aggregate numbers obscure the question that matters most. Who actually holds what, through which infrastructure, and why?

This article maps Wall Street’s crypto ownership across five layers.

SEC 13F Filings Reveal Secrets About Wall Street Crypto ETF Holdings

Institutions still held over 513,000 BTC through ETFs, though filer count declined from 2,173 to 1,867.

Hedge fund exposure declined nearly 10% in Q4, as leverage unwound and the basis spread narrowed.

On the other hand, Brevan Howard cut 17,700 BTC, Harvard trimmed roughly 20%, and Royal Bank of Canada fully exited, all of which are mentioned in the CoinShares Q4 2025 report.

Aggregate pension fund and endowment crypto holdings peaked at $1.48 billion in Q3 2025, then declined to $965 million in Q4.

However, ETFs only reveal who is buying the wrapper. For those who are holding the asset itself, the balance sheets tell a different story.

Corporate Treasuries Show Who Holds Bitcoin Directly on the Balance Sheet

Beyond ETFs, a growing number of public companies hold Bitcoin directly as a treasury reserve asset. As of March 31, 2026, publicly traded companies report a combined 1,134,324 BTC on their balance sheets.

New entrants are reshaping the picture. Trump Media (DJT) held 11,542 BTC before pledging 2,000 BTC as collateral under a hedge arrangement with rehypothecation rights, reducing on-balance-sheet holdings to 9,542 BTC. MARA sold 15,133 BTC in March 2026 at a loss to service debt.

Yet corporate treasuries only account for direct spot ownership. Wall Street’s largest players are building crypto exposure through an entirely different mechanism, one that does not require holding a single Bitcoin.

Tokenized Funds and RWA Holdings Show Where On-Chain Meets TradFi

Some of Wall Street’s largest firms now build crypto exposure without holding a single token. Instead, they put traditional assets on-chain through tokenization.

The firm’s 2026 chairman’s letter reported $65 billion in stablecoin reserves, $80 billion in digital-asset ETPs, and nearly $150 billion in total digital asset-linked AUM.
