BlackRock’s iShares Bitcoin Trust (IBIT) acquired $195.6 million worth of Bitcoin on Tuesday, according to on-chain data from Arkham. This purchase brings the fund’s total Bitcoin holdings over the past month to $1.57 billion.
Flow data indicates that IBIT experienced net inflows of $195.57 million during the trading session, surpassing any other fund’s contribution that day.
Collectively, the group of U.S. spot Bitcoin exchange-traded funds (ETFs) recorded net inflows of $102.67 million for the day, a figure that fell short of IBIT’s individual intake. This suggests that while the overall category saw positive inflows, other ETFs experienced net outflows, effectively making them net sellers during that session.
This positive performance marked a reversal from the previous trading day, when spot Bitcoin ETFs collectively saw outflows of approximately $149 million. IBIT’s substantial buying activity helped to turn the overall tally positive again.
Looking at a broader 30-day perspective, the spot Bitcoin ETF category has attracted about $2.99 billion in net inflows, with IBIT consistently leading as the top recipient. BlackRock’s fund accounts for more than half of this monthly net inflow, with its $1.57 billion in purchases against the category’s $2.99 billion total.
During the trading session in question, Bitcoin’s price traded above $86,000.
How IBIT Drives Bitcoin Demand
IBIT operates through authorized participants, which are large trading firms responsible for creating new ETF shares when investor demand increases and redeeming them when demand wanes.
When investor demand for IBIT shares outstrips the available supply, new shares are created. To maintain a 1:1 backing of each share with actual Bitcoin, the fund must purchase the corresponding amount of the cryptocurrency. This direct link between ETF flows and Bitcoin purchases is why IBIT’s activity is closely monitored, as it translates brokerage account demand directly into buying pressure on the underlying asset.
IBIT’s Dominance in the Spot Bitcoin ETF Market
Launched in January 2024, following the U.S. Securities and Exchange Commission’s approval of spot Bitcoin ETFs, IBIT has rapidly become the largest U.S. spot Bitcoin ETF by assets under management. Its assets under management (AUM) reached $109.34 billion following the latest reporting.
IBIT charges a management fee of 0.25%. BlackRock’s extensive distribution network, which reaches financial advisors, wealth platforms, and institutions, provides a significant advantage over smaller issuers.
The increasing demand for Bitcoin from institutional investors appears to be increasingly channeled through regulated products like IBIT, rather than through direct ownership of the digital currency.
The shift in the ETF category from an outflow of approximately $149 million to an inflow of $102.67 million in consecutive sessions highlights a significant trend. The sustained buying activity of $1.57 billion by IBIT over the past month suggests a consistent trend rather than a short-term fluctuation.
With $109.34 billion in AUM, IBIT has already established itself as the benchmark against which the performance of the broader spot Bitcoin ETF market is measured.
