In the latest crypto news, BlackRock, the global asset management leader, acquired $620 million in Bitcoin and Ethereum on September 16, 2025.
The firm added 2,270 Bitcoin valued at $262.7 million and 78,922 Ethereum worth $357.4 million in one day.
This move pushed its total Bitcoin holdings above 757,000 coins, worth $87.23 billion, and Ethereum to 3.68 million tokens, valued at $16.95 billion.
Analyst Thomas Fahrer noted that BlackRock now controls 762,000 Bitcoin through its iShares Bitcoin Trust. This latest crypto news underscores the firm’s growing commitment to digital assets.
BlackRock executed the purchase on September 16, 2025. The Bitcoin addition totaled 2,270 coins at $262.7 million. Ethereum saw an influx of 78,922 tokens for $357.4 million.
These figures come from on-chain data tracked by Arkham Intelligence. The transaction aligns with broader inflows into BlackRock’s spot ETFs.
iShares Bitcoin Trust recorded $261.8 million in net inflows that day, equivalent to about 2,270 Bitcoin.
Ethereum Trust inflows hit $363.2 million, close to the reported Ethereum buy. In the world of crypto news, such large-scale buys by institutions like BlackRock often signal market confidence.
Fahrer shared the Bitcoin update on X, stating BlackRock bought 2,270 Bitcoin and now holds 762,000 through IBIT. His post, dated September 16, 2025, included a chart showing rapid accumulation.
Other reports confirmed the dual purchase, with one source noting $262.8 million in Bitcoin and $175.6 million in Ethereum, though token counts varied slightly due to price fluctuations.
Crypto news outlets have been quick to cover these details, highlighting the speed of BlackRock’s accumulation.
BlackRock’s Bitcoin stash has grown steadily. From early 2024 to mid-September 2025, IBIT holdings rose from under 100,000 Bitcoin to more than 751,000.
This makes it one of history’s largest accumulators. Fahrer’s analysis, posted on September 16, 2025, highlights this surge via inflow charts.
As crypto news continues to evolve, BlackRock’s trajectory stands out among institutional players.
Ethereum holdings stand at 3.68 million tokens as of September 16, 2025, valued at $16.95 billion. However, on-chain data shows a net drop of nearly 100,000 Ethereum tokens in the prior week, even as dollar value increased.
This reflects trading volatility. Arkham data confirms the overall portfolio value. Recent crypto news has focused on how such fluctuations affect perceptions of institutional strategies.
Recent weeks show consistent inflows. On September 13, 2025, Bitcoin ETFs added $642 million, with BlackRock’s IBIT contributing $265 million. Ethereum ETFs gained $406 million that day.
Earlier, on September 10, 2025, Bitcoin ETFs saw $757 million in inflows, led by Fidelity at $299 million and BlackRock at $211 million.
Ethereum added $171.5 million. These patterns dominate current crypto news discussions around ETF performance.
BlackRock’s total crypto portfolio reached $104.18 billion on September 16, 2025, up from $99.88 billion on September 9.
This $4.31 billion increase stemmed mainly from price gains. Bitcoin rose $4,000, or 3.59%, adding $3.66 billion to holdings.
Ethereum climbed $292, or 6.78%, contributing $645 million. Arkham Intelligence tracked these changes. In crypto news circles, this surge ties directly to broader market recoveries.
The firm hit $100 billion in crypto assets earlier in September 2025, including 750,000 Bitcoin worth $84.6 billion and 3.7 million Ethereum at $16.1 billion.
By mid-month, assets under management in crypto neared 1% of BlackRock’s total $12.53 trillion. Crypto news analysts point to this as evidence of mainstream integration.
Ethereum’s token count fell by about 100,000 from September 9 to 16, 2025, despite value growth. This points to active trading.
Arkham data reveals such patterns in institutional wallets. Earlier in the month, BlackRock sold Ethereum to buy Bitcoin.
On September 3, 2025, it offloaded 72,142 Ethereum for $311.6 million and acquired equivalent Bitcoin.
Another move on September 5 saw $151 million Ethereum sold for $290 million Bitcoin. Such rebalancing features prominently in ongoing crypto news about portfolio management.
These shifts highlight strategic rebalancing. On September 9, 2025, BlackRock added 1,510 Bitcoin and 10,270 Ethereum. By September 15, over $1 billion in Bitcoin flowed in weekly.
BlackRock’s actions fit Wall Street’s push into digital assets. Bitcoin and Ethereum remain top by market value.
Inflows persisted through September 2025. For the week ending September 13, Bitcoin ETFs saw $2.3 billion inflows, with BlackRock and Fidelity leading. Ethereum added $406 million.
