Bitcoin ETFs post $526.6M day as BlackRock IBIT leads
Bitcoin ETFs logged $526.6 million in net inflows on Monday, the strongest daily total in nearly a month, led entirely by BlackRock’s iShares Bitcoin Trust (IBIT). The burst of demand matters because it erased last week’s $228.5 million in withdrawals, even as funds remain about $90.5 million negative for October.
Bitcoin ETFs recorded $526.6 million in net inflows on Monday, the largest single-day total in nearly a month, powered entirely by BlackRock’s iShares Bitcoin Trust (IBIT) with a $665.2 million haul. The surge eclipsed last week’s $228.5 million in outflows and narrows October’s deficit to roughly $90.5 million.
The concentration of demand was stark. Fidelity’s FBTC posted $83.6 million in net redemptions and Grayscale’s GBTC shed $54.9 million, while the remaining U.S. spot bitcoin funds reported no net flows. The last time aggregate inflows were larger was September 22, when the cohort added $714.7 million.
Why did BlackRock dominate Monday’s ETF flows?
BlackRock’s IBIT accounted for all net inflows because its $665.2 million intake outpaced redemptions at other funds, leaving the category with a $526.6 million positive day. No other U.S. spot bitcoin ETF reported net buying, and two major products saw outflows, underscoring how concentrated the session’s demand was.
IBIT’s intake was its biggest since October 7 of last year, highlighting persistent investor preference for the fund even as peers saw withdrawals. The divergence was pronounced: Fidelity’s FBTC lost $83.6 million and Grayscale’s GBTC shed $54.9 million, while every other spot product was flat on the day. The resulting gap left IBIT as the sole engine of category-level growth.

How do the latest inflows stack up against recent weeks?
Monday’s $526.6 million intake was the category’s strongest in nearly a month and trailed only the $714.7 million added on September 22 over that span. The single day of buying also more than offset the prior week’s $228.5 million of withdrawals, trimming October’s cumulative net outflow to about $90.5 million.
That reversal highlights a sharp, one-session swing in demand after a stretch of choppier activity. It also marks IBIT’s return to peak daily intake territory, with its $665.2 million print the largest for the fund since October 7 of last year. By contrast, the day’s redemptions at FBTC and GBTC—$83.6 million and $54.9 million, respectively—show continued divergence within the segment.
What does this concentration mean for Bitcoin ETF market share?
The day’s flows indicate market share gains for IBIT, as all net buying accrued to the fund while competitors either saw redemptions or were flat. With no other spot bitcoin ETF posting net inflows, the session’s leadership sat exclusively with BlackRock’s vehicle.
The split also underscores investor selectivity within the spot ETF lineup. While the category registered its biggest daily net addition in nearly a month, the flow pattern was far from uniform. Two marquee products—FBTC and GBTC—registered outflows, and every other product recorded zero net flows, leaving the cohort’s positive print to rest solely on IBIT’s intake.
What should investors watch next?
The key question is whether IBIT’s $665.2 million day proves repeatable and if it can swing October’s cumulative flows positive from the current roughly $90.5 million deficit. Sustained intake would build on Monday’s reversal, while renewed redemptions at peers could keep aggregate figures volatile.
Another marker is whether the category can top the September 22 high-water mark of $714.7 million in a single day. For now, the latest session establishes IBIT’s dominance with its biggest daily intake since October 7 last year, even as several rivals saw net outflows or flat prints.
Flows remain the clearest read on positioning across spot bitcoin ETFs. Monday’s burst erased last week’s net redemptions and delivered the strongest daily tally in weeks, but the month-to-date picture is still slightly negative. Follow-through will determine whether this snapshot becomes a trend.
