U.S. Bitcoin ETFs See $1B Inflows Again, Historically a Signal of Local Market Peaks

7/10/2025 – BlackRock’s Bitcoin ETF Tops Revenue Charts as U.S. Flows Hit $1.2B

BlackRock’s iShares Bitcoin Trust (IBIT) has emerged as the firm’s most profitable ETF, generating an estimated $244.5 million in annual revenue while managing nearly $100 billion in assets.

On Monday, U.S. Bitcoin ETFs collectively saw a $1.2 billion net inflow, marking the seventh time inflows have surpassed $1 billion, according to Farside data. The lion’s share of Monday’s inflows—$970 million—went into BlackRock’s IBIT.

Historically, when inflows hit the $1 billion mark, they have often coincided with short-term tops in Bitcoin’s price.

March 12, 2024: Inflows preceded a Bitcoin peak near $74,000 on March 14.
November 2024: Two $1B inflows appeared just before Bitcoin climbed past $100,000, with the rally topping in December.
January 17, 2025: A $1B inflow preceded a local peak near $109,000 on January 20.
July 10–11, 2025: Consecutive $1B inflows came ahead of a short-term high of $123,000 on July 14.

Bitcoin briefly surged above $126,000 on Monday and is trading near $124,000, leaving market watchers to see whether a new peak forms in the coming days.

Revenue and Growth Highlights
Senior Bloomberg ETF Analyst Eric Balchunas noted that IBIT is now BlackRock’s top revenue-generating ETF, surpassing the iShares Russell 1000 Growth ETF. The fund has amassed nearly $100 billion in assets under management (AUM) in just 435 days, a record pace compared to the Vanguard S&P 500 ETF (VOO), which reached the milestone in 2,011 days.

The combination of massive inflows and rapid AUM growth underscores IBIT’s position as a cornerstone of both BlackRock’s ETF lineup and the broader institutional adoption of Bitcoin ETFs.
