A new market report revealed that BlackRock, the world’s largest asset manager, aggressively expanded its crypto portfolio in the third quarter of 2025, adding a staggering $22.46 billion in digital assets, Coinidol.com reports.
This massive influx of capital boosted the firm’s total cryptocurrency holdings to over $102 billion, solidifying its position as the largest institutional holder of digital assets globally.
BlackRock’s ETH inflows
The most compelling detail of the report, however, was the change in internal portfolio dynamics. For the first time in the firm’s history, Ethereum (ETH) inflows outpaced Bitcoin (BTC) in quarterly growth. While Bitcoin contributed $10.99 billion in gains, Ethereum posted a more dramatic move, soaring by $11.46 billion, representing a colossal 262% increase in BlackRock’s ETH exposure for the quarter, as Economic Times reported.
This significant change suggests a maturation of institutional appetite beyond just Bitcoin as a store of value. It indicates that large, regulated financial players are increasingly recognizing Ethereum’s utility, smart contract ecosystem, and staking potential as critical components for portfolio diversification.
A signal of the crypto market changes
Furthermore, the momentum has continued into the start of the fourth quarter. Data up to October 8 showed BlackRock’s portfolio expanding by another $10.43 billion in the first eight days of the month, averaging over $1 billion in fresh value per day. This sustained activity underscores a fierce institutional rush into the market, suggesting that the “crypto winter” is a firmly distant memory, replaced by what analysts are calling a structural bull market driven by traditional finance giants.
As of October 8, BlackRock’s total Ethereum holdings were valued at $18.26 billion, up from $15.91 billion just one week prior, signaling a high-conviction bet on the altcoin’s future.
