BlackRock Bitcoin ETF Allocation Expands as Digital Assets AUM Rebounds 63 Percent in Q3

On October 14, 2026, BlackRock released its Q3 2026 earnings for the period ended September 30, showing digital assets assets under management rebounded 63 percent to approximately $79.6-80 billion from $48.8 billion at the end of Q2. The increase stemmed primarily from the iShares Bitcoin Trust spot Bitcoin ETF amid broader market recovery.

IBIT Holdings and Market Position

IBIT held between 801,000 and 806,000 BTC valued at roughly $67-68 billion, accounting for 60-62 percent of the 1.29 million BTC held across all U.S. spot Bitcoin ETFs. Holdings rose from about 734,000 BTC at the close of Q2. The fund maintained its position as the dominant vehicle in the category with more than 60 percent of spot Bitcoin ETF AUM.

Net inflows into digital assets reached $7.9 billion during the quarter, the strongest figure since Q3 2025. Market appreciation added another $22.9 billion as Bitcoin prices increased more than 42 percent. These inflows reversed the $2.2 billion in net outflows recorded during the first half of the year. Despite the rebound, digital assets AUM remained 23 percent below the September 2025 peak of approximately $104 billion.

BlackRock’s total AUM reached a record $15.5 trillion after $205 billion in net inflows during Q3. Daily ETF flows have stayed volatile through mid-October, with on-chain data indicating minor ongoing adjustments to IBIT’s Bitcoin holdings.

13F Filings and Institutional Context

BlackRock’s Q2 2026 13F filing submitted in August showed increased proprietary holdings in IBIT, including roughly 15 million shares. Q3 2026 13F reports covering positions as of September 30 are due around November 16. Early filings from other managers have indicated continued or higher exposure to IBIT, though BlackRock’s own Q3 13F has not yet been released.

IBIT launched in early 2024 after the SEC approved spot Bitcoin ETFs. BlackRock positioned the product as a core institutional offering with a lower fee structure that supported sustained inflows compared with competing funds. The latest earnings release provides the most recent verified snapshot of scale and flows ahead of the next round of institutional ownership disclosures.

Subsequent quarterly updates from BlackRock and ongoing ETF flow reports will supply additional data on allocation trends. Investors tracking 13F filings can compare proprietary positions against the broader AUM and inflow figures already disclosed.
