BlackRock Inc. (NYSE: BLK) has seen its cryptocurrency portfolio rocket by nearly $30 billion during the third quarter (Q3) of 2026.
BlackRock’s crypto trove soared by $29.54 billion over the past three months, starting from July 1 , according to data Finbold fetched from Arkham Intelligence on September 30, 2026.
At the time of writing, BlackRock held about $77.1 billion in crypto assets, having gained from $47.56 billion at the start of this quarter.
As a result, the firm’s cryptocurrency portfolio has grown by roughly 62.11% over the past three months. This significant gain in Q3 was catalyzed by crypto’s uptrend amid its aggressive accumulation.
As of press time, Bitcoin (BTC) price had risen by over 42% in Q3 2026, up from $58,564 on July 1 to nearly $84,000 on Wednesday. On the other hand, Ethereum (ETH) price has rallied by more than 70% during the same period, up from $1,570 at the beginning of the quarter to $2,667 at press time.
BlackRock’s crypto holdings change for Q3 2026
At the beginning of Q3 2026, the iShares Bitcoin Trust (IBIT) held about 738,200 BTC, valued at around $43.23 billion. However, IBIT has accrued 63,070 BTC, representing an 8.54% gain, and holds 801,270 coins at the time of publication.
On the other hand, BlackRock’s two ETH spot exchange-traded funds (ETFs): iShares Ethereum Trust ETF (ETHA) and iShares Staked Ethereum Trust ETF (ETHB) opened the quarter with 2.75 million ETH. During the past three months, this fund manager purchased over 1 million ETH, representing a 36.49% uptick.
Consequently, BlackRock held 3.76 million ETH at the time of reporting. As such, BlackRock’s investors leaned more heavily on Ethereum than Bitcoin during the third quarter of 2026, despite BTC accounting for 80.57% of its crypto portfolio gains.
