BlackRock crypto ETF portfolio falls $4.77 billion in early November

What happened

Coinpedia reported on November 10 that BlackRock's cryptocurrency portfolio had fallen by $4.77 billion so far in November 2026, citing Arkham Intelligence. The portfolio was $66.39 billion at the time of the report, compared with $71.17 billion at the start of the month.

The decline was concentrated in BlackRock's spot crypto ETFs. Coinpedia said the iShares Bitcoin Trust, or IBIT, lost $3.89 billion, or about 6.09%, leaving it with $59.96 billion in net assets, down from $63.85 billion. The iShares Ethereum Trust ETF, ETHA, fell by $883.29 million, or 12.06%, to $6.44 billion over nine days.

The report also tracked token holdings. IBIT's Bitcoin position dropped to 796,705 BTC from 815,657 BTC, a reduction of 18,942 BTC or 2.32%. ETHA's Ethereum holdings fell by 199,957 ETH to 3.02 million ETH, a 6.21% decline. Coinpedia said Bitcoin and Ether had fallen 5.21% and 10.36%, respectively, over the prior seven days.

Separately, The Crypto Basic's November 9 daily edition rounded up other crypto developments. It reported that Coinbase completed the approval process for Coinbase National Trust Company, that PNC and Coinbase announced a USDC payment pilot for eligible corporate and institutional customers, and that Strategy and Bitmine disclosed additional Bitcoin and Ether purchases.

Why it matters

BlackRock is one of the largest issuers of spot crypto ETFs, so changes in IBIT and ETHA are closely watched as a gauge of how institutional exposure is moving. Coinpedia's figures show the ETF-linked portion of BlackRock's crypto holdings shrank alongside a weak period for Bitcoin and Ether.

The figures describe holdings and asset values over a specific window; they do not establish why investors acted or what will happen next. The TCB roundup shows that ETF and trust structures are not the only institutional channels: banks, public companies and tokenized-securities venues are also developing crypto-related products.

What the data shows

Coinpedia, citing Arkham Intelligence, reported BlackRock's crypto portfolio at $66.39 billion, down $4.77 billion from $71.17 billion. IBIT stood at $59.96 billion, down $3.89 billion or 6.09% from $63.85 billion. ETHA stood at $6.44 billion, down $883.29 million or 12.06%. IBIT held 796,705 BTC, down 18,942 BTC or 2.32% from 815,657 BTC. ETHA held 3.02 million ETH after a 199,957 ETH decline, a 6.21% reduction. Over seven days, BTC fell 5.21% and ETH fell 10.36%.

Background

BlackRock's IBIT and ETHA are spot ETFs that hold Bitcoin and Ether. Coinpedia used Arkham Intelligence data to compare holdings at the start of November with levels at the time of publication. The Crypto Basic's daily edition, meanwhile, reported on Coinbase National Trust Company's charter effective November 6 after preliminary approval in April, the PNC-Coinbase USDC pilot, Strategy's purchase of 1,036 BTC between November 2 and November 8 at an average cost of $79,012 including expenses, and Bitmine's acquisition of 9,587 ETH, bringing its holdings to 6,070,092 ETH as of November 8. It also covered Sharplink's third-quarter results, Formation Securities' SEC notice for a Solana-based tokenized securities venue planned for early 2027, and Ava Labs' role providing the settlement ledger for a tokenized securities platform affiliated with NYSE.

What to watch

Future updates to Arkham data or issuer disclosures will show whether the November decline in IBIT and ETHA holdings continues. The Crypto Basic reported that the NYSE-affiliated tokenized securities platform and Formation Securities' Solana venue are subject to regulatory approvals or expected launch timing, so their progress is separate from the ETF holdings story but relevant to how crypto market infrastructure develops.
