BlackRock's iShares Bitcoin Trust, known by its ticker IBIT, attracted a net $665.2 million on October 19, according to Farside Investors' daily U.S. spot bitcoin exchange-traded fund table. The wider group gained a smaller $526.7 million because outflows from Fidelity and Grayscale products offset part of IBIT's intake. The contrast makes the session notable: money returned to the category, but the positive result was concentrated in one fund rather than spread across issuers.

One large inflow, two offsets

Farside's figures, reported in millions of dollars, show an $83.6 million net withdrawal from Fidelity's bitcoin fund and a $54.9 million withdrawal from Grayscale's original Bitcoin Trust on the same date. The other funds in its table showed zero net flow for the session. Adding those two withdrawals to IBIT's $665.2 million produces the group's $526.7 million net gain, allowing for the table's rounding. The Block separately reported a $665.16 million IBIT figure from another data provider and roughly $526.6 million across the category; the small differences reflect reporting precision rather than a different direction of flows.

The swing followed a weaker end to the previous week. Farside recorded $82.4 million in net withdrawals from the group on October 16, including $71.8 million from IBIT. Earlier October sessions also alternated between inflows and outflows. That sequence is a reason to avoid reading Monday's print as a durable reversal. Daily creations and redemptions measure changes in fund shares and cash flows; they do not, by themselves, show whether the same investors are building a long-term position.

Why the concentration matters

IBIT's size gives its daily activity an outsized effect on the aggregate. BlackRock listed about $65.7 billion in net assets for the trust as of October 19. It describes the product as an exchange-traded vehicle designed to reflect bitcoin's price while leaving custody and operational handling to the fund structure. For investors and market observers, the distinction between IBIT's gross inflow and the category's smaller net gain matters because a headline focused on one fund can conceal selling elsewhere in the same market.

This flow report is separate from BlackRock's October 19 filing for a proposed bitcoin fund with a managed-protection strategy. IBIT is an existing product, while that new proposal remains a filing rather than an approved or trading fund. The October 19 flow figures describe trading in existing U.S. spot bitcoin funds; they should not be attributed to the proposed product. Nor do they prove that ETF buying caused any particular move in bitcoin's price, which is influenced by activity across many spot and derivatives venues.

What the next reports can establish

The next daily tables will show whether demand continues, broadens beyond IBIT or gives way to renewed redemptions. Fund-flow estimates can also be revised, so figures should be read with their date and provider attached. Monday's evidence supports a narrow conclusion: U.S. spot bitcoin ETFs had a positive October 19 session, led by one BlackRock fund, while two rivals recorded outflows. It does not identify the buyers, their motives or the direction of the market ahead.
