BlackRock's iShares Bitcoin Trust (IBIT) led a massive influx of capital into U.S. spot Bitcoin ETFs, attracting approximately $350.3 million in net inflows on Tuesday, September 22. This was part of a broader $714.7 million inflow day for all similar ETFs, marking the fourth consecutive day of positive flows. The total for this four-day streak has now surpassed $2.3 billion.
The substantial demand for IBIT and other Bitcoin ETFs has coincided with a significant rally in Bitcoin's price, which has pushed above $86,000 and briefly topped $87,000. The inflows on Tuesday followed a near $1 billion surge on Monday, which was the largest single-day intake for these funds in approximately 11 months, underscoring strong renewed institutional interest.
