BlackRock’s iShares Bitcoin Trust (IBIT), a spot Bitcoin exchange-traded fund (ETF), has reached a new milestone—holding over 700,000 BTC, equivalent to approximately $75.5 billion in assets under management (AUM). This follows a $164.6 million inflow recorded on Monday.
According to Apollo co-founder Thomas Fahrer, IBIT now holds 700,307 BTC, marking a steady increase from the 698,919 BTC reported on BlackRock’s iShares website as of 3rd July. This suggests the fund acquired another 1,388 BTC across just two trading sessions.
BlackRock Dominating the U.S. Spot Bitcoin ETF Landscape
IBIT now accounts for more than 55% of all Bitcoin held within U.S. spot Bitcoin ETFs, based on data from Bitbo. Since its launch in January 2024, the fund has produced a total return of 82.67%, signaling strong investor confidence in the product.
Notably, recent reports suggest IBIT is generating more revenue than BlackRock’s flagship S&P 500 ETF, the iShares Core S&P 500 (IVV). This marks a significant shift in BlackRock’s earnings structure, highlighting growing demand for crypto-linked investment products.
Institutional Demand Surpasses Bitcoin Miner Supply
A new analysis from Galaxy Research shows that U.S. Bitcoin ETFs—alongside Michael Saylor’s MicroStrategy—have collectively purchased more Bitcoin than miners have issued nearly every month in 2025. In total, these entities have invested $28.22 billion in Bitcoin this year.
By contrast, Bitcoin miners’ net new issuance in the same period amounts to $7.85 billion. The only exception so far was February, when the combined cohort sold $842 million in Bitcoin.
With institutional appetite soaring and spot ETF inflows continuing to climb, BlackRock’s IBIT appears poised to further bolster its market position—both among ETFs and within the broader crypto ecosystem.
