BlackRock, the world’s largest asset manager, saw the value of its on-chain cryptocurrency portfolio decline sharply in the first quarter of 2026, as falling prices offset continued Bitcoin (BTC) accumulation and ongoing Ethereum (ETH) outflows.
Between January 1 and March 31, 2026, the combined value of BlackRock’s Bitcoin and Ethereum holdings dropped from $78.36 billion to $57.89 billion, representing a $20.47 billion decrease, or a 26.12% decline, based on data calculated by Finbold from blockchain analytics platform Arkham.
The decline was driven primarily by market conditions rather than capital exiting the portfolio, with Bitcoin holdings increasing over the period while Ethereum exposure contracted.
Bitcoin accumulation continues despite $16 billion valuation drop
Bitcoin remained the dominant component of BlackRock’s crypto allocation, though its dollar value declined significantly due to price pressure.
Over the quarter, Bitcoin prices fell from $88,341 to $65,982, a 25.31% decline. As a result, the value of BlackRock’s BTC holdings dropped from $68.05 billion to $51.81 billion, representing a $16.24 billion decrease.
Despite the drawdown, BlackRock continued to accumulate Bitcoin. Holdings increased from approximately 770,290 BTC to 785,240 BTC, an addition of 14,950 BTC, or 1.94% growth during the quarter.
The divergence between rising holdings and falling value highlights that the decline was largely price-driven rather than the result of net selling.
Ethereum declines reflect both price pressure and net distribution
Ethereum experienced a more pronounced contraction, with both price declines and reduced holdings contributing to the drop in valuation.
ETH prices fell from $2,966 to $1,983, marking a 33.12% decline over the quarter. At the same time, BlackRock reduced its Ethereum holdings from approximately 3.47 million ETH to 3.06 million ETH, a decrease of 410,750 ETH, or 11.82%.
In dollar terms, Ethereum exposure declined from $10.31 billion to $6.08 billion, representing a $4.23 billion decrease. Unlike Bitcoin, Ethereum’s performance reflects a combination of market depreciation and active distribution, signaling a shift in positioning.
Losses moderate compared to Q4 2025 drawdown
While Q1 2026 marked a significant decline, the pace of losses slowed compared to the previous quarter.
In Q4 2025, BlackRock’s crypto portfolio fell from $103.8 billion to $77.35 billion, a $26.44 billion decrease. During that period, Bitcoin declined by $20.74 billion, while Ethereum fell by $5.71 billion, both driven largely by price corrections.
Quarter-over-quarter, the total decline improved by $5.97 billion, indicating that while market conditions remained weak, the rate of contraction eased entering 2026.
2025 comparison shows sharp deterioration in market conditions
Compared to the first quarter of 2025, the scale of losses has increased substantially. In Q1 2025, BlackRock’s crypto portfolio declined by $4.95 billion, with Bitcoin falling $3.54 billion and Ethereum decreasing by $1.41 billion.
At the time, both assets were still in an accumulation phase. Bitcoin holdings rose by 23,300 BTC, while Ethereum holdings increased by 120,350 ETH, reflecting continued inflows despite temporary price weakness.
By contrast, Q1 2026 shows a clear divergence: Bitcoin accumulation persists, but Ethereum has shifted from accumulation to net outflows, amplifying the overall decline in portfolio value.
Institutional positioning shifts as market dynamics evolve
The data underscores a changing institutional landscape within crypto markets. Bitcoin continues to function as the core strategic allocation, with steady accumulation even during periods of declining prices. This behavior suggests that institutional demand remains intact, with capital being deployed opportunistically during drawdowns.
Ethereum, however, appears to be undergoing a rebalancing phase, with reduced holdings indicating either profit-taking, risk management, or a shift in allocation preferences.
Price-driven drawdown not capital flight
Importantly, the Q1 2026 decline does not represent a traditional “outflow” event. Instead, it reflects a mark-to-market contraction driven primarily by falling asset prices.
The increase in Bitcoin holdings alongside a sharp decline in valuation highlights that capital has not exited the market at the same scale implied by the headline figures.
Rather, BlackRock’s crypto exposure continues to evolve beneath the surface, with accumulation in Bitcoin offsetting broader market weakness and selective reductions in Ethereum positioning.
Client-driven flows through ETFs
The Bitcoin and Ethereum tracked in this report reflect assets held in custody through BlackRock’s ETF platform, primarily the iShares Bitcoin Trust (IBIT) and iShares Ethereum Trust (ETHA).
These holdings are accumulated or reduced in response to investor demand for the ETFs, rather than representing proprietary crypto positions taken by BlackRock itself.
In that sense, BlackRock acts as the issuer and intermediary for regulated market access, while the underlying exposure is driven by client capital flowing into or out of its products.
