BlackRock trims 3,710 BTC, adds 196,340 ETH over 37 days

BlackRock Inc. (NYSE: BLK) has expanded the value of its cryptocurrency holdings by more than $3.7 billion since early July, as onchain data points to a potential shift in investor allocation from Bitcoin (BTC) to Ethereum (ETH). According to Arkham Intelligence, BlackRock's iShares Bitcoin Trust ETF (IBIT) reduced its Bitcoin position by 3,710 BTC over the period, moving from 743,190 BTC on July 1, 2026, to about 749,480 BTC as of August 6. In contrast, the iShares Ethereum Trust ETF (ETHA) increased its holdings by 196,340 ETH. ETHA's Ethereum balance rose from 2.77 million ETH on July 1 to roughly 2.97 million ETH at press time. With ETH trading at $1,868 on Thursday, BlackRock's Ethereum stash was valued at about $5.54 billion, an increase of $1.08 billion over the past 37 days. Over the same span, the value of the firm's Bitcoin holdings climbed by $2.67 billion to around $47.35 billion, supported by higher BTC prices despite a 0.5% decline in BTC holdings. BTC advanced by $3,909, or 6.5%, from $60,128 on July 1 to above $64,037 at the time of reporting. As investors stepped up Ethereum buying and trimmed Bitcoin exposure, the ETH/BTC pair emerged from a multimonth capitulation, as noted by Aksel Kibar. ETH/BTC is up more than 5% since early July and was trading at 0.02958 at press time. Kibar said that if the same pattern persists—accumulating Ethereum while selling Bitcoin—ETH/BTC could move toward 0.0312.
