The world’s largest asset manager, BlackRock, made a bold statement in the digital asset space during the first half of 2025—adding nearly $24 billion to its cryptocurrency portfolio. This strategic expansion underscores a growing institutional embrace of blockchain-based assets, with Bitcoin and Ethereum leading the charge.
According to data from Finbold’s H1 2025 Crypto Market Report, BlackRock’s total crypto holdings surged from $54.77 billion** on January 1 to **$78.67 billion by June 30—a remarkable increase of 30.38% in just six months. The surge was primarily driven by inflows into its newly launched spot Bitcoin and Ethereum ETFs, which began trading early in the year.
Bitcoin Dominates Growth
Bitcoin remains the cornerstone of BlackRock’s digital asset strategy. The firm’s BTC holdings skyrocketed from $51.16 billion** to **$74.47 billion, representing an addition of $23.3 billion—a 31.3% rise. This aggressive accumulation reflects strong investor demand for regulated exposure to Bitcoin through exchange-traded products.
BlackRock has been actively purchasing Bitcoin on-chain to back its spot Bitcoin ETF, ensuring full asset backing and transparency. These verifiable transactions have contributed to increased market confidence and put further pressure on competitors to match the pace of institutional adoption.

Ethereum’s Steady Rise
While Bitcoin dominates in scale, Ethereum also played a crucial supporting role in BlackRock’s portfolio growth. ETH holdings increased from $3.53 billion** to **$4.21 billion, a gain of $678.95 million (up 16.15%). This growth aligns with the launch of BlackRock’s spot Ethereum ETF, which has attracted steady capital inflows amid growing interest in smart contract platforms and decentralized applications.
The firm's dual focus on both leading cryptocurrencies highlights a balanced approach: leveraging Bitcoin as a digital store of value while recognizing Ethereum’s foundational role in the broader Web3 and decentralized finance (DeFi) ecosystems.
Q1 to Q2: A Period of Rapid Expansion
At the close of the first quarter of 2025, BlackRock held approximately:
- 575,860 BTC
- 1.17 million ETH
With a total crypto portfolio valued at $49.85 billion, the momentum picked up significantly in Q2. By June 30, the portfolio had ballooned to:
- $74.47 billion in BTC
- $4.21 billion in ETH
This brought the combined total to $78.67 billion**, marking a staggering **$28.82 billion increase between Q1 and Q2 alone.
The $23.91 billion net gain across H1 2025 is largely traceable through public blockchain data, offering rare transparency into institutional crypto activity. However, experts caution that these figures likely represent only part of the full picture.
Beyond On-Chain Data: The Hidden Depth of Exposure
While on-chain wallets linked to ETF custody provide verifiable insights, they don’t capture BlackRock’s complete crypto footprint. The firm may also hold digital assets through:
- Over-the-counter (OTC) trading desks
- Private custody arrangements
- Indirect exposures via derivatives or fund-of-funds structures
As such, analysts believe BlackRock’s true cryptocurrency exposure could be even higher than reported figures suggest. This layered approach allows flexibility in managing risk, optimizing tax efficiency, and responding to regulatory nuances across jurisdictions.

Institutional Adoption Reaches Inflection Point
BlackRock’s aggressive expansion signals a pivotal moment in the maturation of the crypto market. Once viewed with skepticism by traditional finance, digital assets are now integral to mainstream investment strategies.
The success of BlackRock’s spot ETFs has not only driven asset inflows but also legitimized crypto as a viable asset class for pension funds, endowments, and retail investors alike. Regulatory clarity, improved custody solutions, and growing macroeconomic uncertainty have all contributed to this shift.
Moreover, BlackRock’s entry has catalyzed competition. Firms like Fidelity, ARK Invest, and VanEck have accelerated their own crypto ETF launches, creating a robust ecosystem of regulated investment vehicles.
