BlackRock clients net purchase $273M in Bitcoin this week

BlackRock’s iShares Bitcoin Trust is back in accumulation mode. After weeks of institutional investors heading for the exits, IBIT pulled in roughly $319 million in inflows between July 20 and 22 alone, making it the dominant force behind a $499 million weekly haul across all US spot Bitcoin ETFs.

The recent buying spree recovers only about 15% of the damage done during June’s sell-off, and total Bitcoin ETF flows for 2026 are still sitting at negative $4.76 billion.

From panic selling to cautious buying

During the week of June 22 to 26, IBIT accounted for approximately 73% of total Bitcoin ETF outflows, bleeding roughly $1.30 billion in a single week.

On July 6, IBIT recorded $209.4 million in inflows as part of a broader $265.7 million daily total across Bitcoin ETFs. The week before that saw approximately $204 million flow into the fund. And now, the latest weekly figures show the buying pressure accelerating further.

As of July 30, IBIT held approximately 739,066 BTC, valued at around $47.67 billion in net assets. That’s roughly 3.5% of all Bitcoin that will ever exist, locked up in a single ETF wrapper.

The institutional sentiment barometer

IBIT has consistently led the pack among US spot Bitcoin ETFs in both directions, attracting the lion’s share of inflows during bullish periods and absorbing the brunt of outflows during downturns. Its dominance in the current recovery is consistent with that pattern.

A $319 million weekly inflow sounds impressive until you remember it’s following $1.3 billion in outflows from a single week in June.

What this means for investors

The $4.76 billion net negative flow figure for 2026 represents real capital that left the Bitcoin ETF ecosystem and hasn’t come back. For sustained price appreciation, Bitcoin needs not just a return to positive weekly flows but enough cumulative buying to offset the hole created earlier this year.

IBIT’s outsized role in both inflows and outflows means BlackRock’s client base is effectively setting the tone for the entire Bitcoin ETF market. That concentration of influence in a single product creates both opportunity and fragility.

The pattern worth monitoring is whether weekly inflows can consistently stay above the $200 million threshold. Two consecutive weeks above that level would be the most bullish signal Bitcoin ETFs have produced since the early months of 2026.
