BlackRock’s iShares Bitcoin Trust (IBIT) experienced $65.4 million in net outflows on October 12, 2026, a figure that accounted for the entirety of the US spot Bitcoin ETF market’s outflows that day, according to data from SoSoValue.
IBIT Leads Market Outflows
Notably, all other spot Bitcoin ETFs saw no inflows or outflows, leaving IBIT as the sole fund with significant trading activity. This redemption occurred just days after a more substantial outflow event. On October 7, US spot Bitcoin ETFs collectively recorded their peak single-day outflow for the month, totaling $484.9 million. IBIT was responsible for $207.7 million of that total, representing just under half of the day’s withdrawals. The October 12 outflow was approximately one-third the size of IBIT’s redemption on October 7.
Context of Outflows
IBIT’s cumulative net inflows to date stand at approximately $65.67 billion. Against this substantial figure, the recent $65.4 million exit represents about one-tenth of a percent. Collectively, US spot Bitcoin ETFs manage around $106 billion in assets, which equates to roughly 6.35% of Bitcoin’s total market capitalization.
During this period, Bitcoin has been trading in the low to mid-$80,000 range. Market pressures appear to be stemming from outside the cryptocurrency sector, with rising Treasury yields and a shift in risk sentiment impacting assets often categorized as speculative.
IBIT’s Dominance and Investor Behavior
IBIT maintains its leading position among Bitcoin ETFs in terms of both assets under management and historical inflows. Spot Bitcoin ETFs have emerged as a primary avenue for traditional investors seeking exposure to Bitcoin, with wealth managers, advisors, and institutions frequently opting for the familiar structure of a fund over direct coin ownership.
The isolated nature of the October 12 outflow is particularly noteworthy. With no other funds experiencing movement, the redemptions suggest decisions made specifically by IBIT holders rather than a widespread exit from the market. However, the data does indicate a reduction in the scale of selling compared to the October 7 spike, with a $65.4 million outflow significantly smaller than the $484.9 million recorded on that earlier date. Given that spot Bitcoin ETFs now represent approximately 6.35% of Bitcoin’s market capitalization, these flows carry considerable influence.
