Summary
BlackRock's iShares Bitcoin Trust (IBIT) recorded its largest daily net inflow in the past year, signaling resilient institutional demand for bitcoin despite macroeconomic pressures. According to data from SoSoValue, IBIT logged $665.16 million in net inflows on Monday, its biggest single-day inflow since Oct. 7, 2025. The inflows drove U.S. spot bitcoin ETFs to net inflows of $526.6 million for the day, even as outflows from Fidelity's and Grayscale's funds partially offset IBIT's gains.

The activity contrasted with the broader crypto ETF market. Spot ether ETFs saw another day of net outflows worth $103.3 million on Monday, extending their negative streak to four days.

Bitcoin remained confined to a tight $82,000 to $83,000 consolidation zone, as fears that further interest-rate hikes could weigh on broader risk assets kept price action choppy. Zeus Research analyst Dominick John told The Block that BlackRock's inflows signal resilient institutional demand despite macro headwinds, though persistent resistance suggests ETF buying is being absorbed by selling pressure.

Min Jung, associate researcher at Presto Research, said the exact driver of IBIT's inflows is unclear but noted investors could be positioning for a potential "catch-up trade" in bitcoin, which has lagged other risk assets trading near all-time highs amid a lack of crypto-specific catalysts. Jung cautioned that volatility is likely to persist while uncertainty around the Federal Reserve's rate decision dampens risk sentiment, and that a sustained breakout above the current range would require macro clarity and improved risk appetite. The Block's crypto Fear & Greed Index stood at 59, in the "greed" zone.

IBIT, launched in January 2024 by the world's largest asset manager, is the largest spot bitcoin ETF with $66.37 billion in net assets. On the same day, BlackRock filed for another bitcoin product, the proposed iShares Bitcoin Managed Protect ETF, which would offer investors downside protection alongside upside exposure to its flagship bitcoin ETF.
