iShares Bitcoin Trust Soars to $62B AUM on Record-Setting Quarterly Inflows
iShares Bitcoin Trust (IBIT) has continued its dominance in the spot Bitcoin ETF market, attracting $3.7 billion in net inflows this quarter and pushing its total assets under management to $62.6 billion.
This represents a significant increase from the end of June 2026, when IBIT's AUM sat at around $43.4 billion. The fund added approximately $19 billion in total value over the span of a single quarter, a combination of fresh investor capital and Bitcoin price movement.
The quarterly haul underscores a widening gap between IBIT and every other spot Bitcoin ETF on the market. While BlackRock's product hoovers up billions, many of its competitors have been watching capital walk out the door.
The current inflow streak is notable partly because it represents a sharp turnaround from earlier periods of net outflows in 2026. The distinction between inflow-driven and price-driven AUM growth matters here. While Bitcoin's own price movements have contributed to IBIT's ballooning asset base, the $3.7 billion in quarterly net inflows represents genuine new capital entering the fund.
The dominance of IBIT is reshaping how capital flows into Bitcoin. The fund has effectively become the primary gateway for institutional Bitcoin exposure in the US. Sustained ETF inflows create consistent buying pressure for Bitcoin itself, translating to billions of dollars in demand that wouldn't otherwise exist in the spot market.
This structural demand floor didn't exist before January 2024, when IBIT launched. Cumulative net inflows into IBIT since its launch now exceed $63.9 billion, surpassing 100% of total net inflows across the entire US spot Bitcoin ETF category.
