IBIT added $665.16 million on Monday, the most since Oct. 7, 2025, per SoSoValue. The fund launched in January 2024 and has grown to $66.37 billion in net assets, the largest spot bitcoin ETF.
Across the category, U.S. spot bitcoin ETFs still tallied $526.6 million of net inflows that day, even with Fidelity and Grayscale seeing redemptions that chipped away at IBIT's strength. Ether told the opposite story, with spot ether ETFs recording $103.3 million in net outflows, the fourth straight day of withdrawals.
The surge arrived while bitcoin hovered between 82,000 and 83,000 dollars, a narrow band shaped by worries that more interest rate hikes could pressure risk assets. "BlackRock's inflows signal resilient institutional demand despite macro headwinds and bitcoin's choppy price action," Zeus Research Analyst Dominick John told The Block. He added, "Persistent resistance suggests ETF buying is being absorbed by selling pressure, while rate-hike fears weigh on broader risk appetite."
Min Jung at Presto Research said the inflow driver is not obvious, but investors may be leaning into positioning for a catch-up move in bitcoin. Jung contrasted this with other risk assets near record highs, noting that bitcoin has been stuck in a range with few crypto-specific catalysts, which can make current levels appear attractive. The backdrop is still volatile as the Federal Reserve's rate decision remains unclear.
Jung said a durable move out of the current range likely needs macro clarity and better risk appetite. The Block's crypto Fear and Greed Index sits at 59, firmly in greed.

Flows can lead prices, but they do not guarantee momentum. IBIT's haul shows demand is there while spot ether ETFs leak assets, and BlackRock is already seeking another product, the iShares Bitcoin Managed Protect ETF, designed to provide downside protection while linking gains to its primary bitcoin ETF. The bottom line: the bid is resilient, the range is stubborn, and macro still sets the ceiling.
