Spot Bitcoin ETFs roared back with $2.71 billion in weekly inflows from October 6-10. This move reversed the previous week’s $902.50 million outflows and is the second-largest weekly total for October.

Bitcoin ETFs Reverse Course with $2.71B Weekly Surge

Bitcoin ETF products recorded $2.71 billion in weekly net inflows from October 6 to 10. This represents a major reversal from the $902.50 million in outflows recorded during the week of September 26.

The strong performance is the second-largest weekly inflow for October, trailing only the $3.24 billion figure for the week of October 3. Total Bitcoin ETF assets under management reached $158.96 billion by the end of the week.

Weekly trading volume reached $34.56 billion, indicating heightened activity as Bitcoin recovered from tariff-driven lows around $104,000 to trade above $114,000. Cumulative total net inflows reached $62.77 billion across all Bitcoin ETF products since launch.

The weekly performance follows a volatile September that saw alternating periods of strong inflows and outflows. The week of September 19 posted $886.65 million in inflows, while the week of September 12 recorded $2.34 billion. The week of September 26 represented the largest single-week redemption since the launch.

October 10 daily flows showed modest $4.50 million in net outflows. This shows profit-taking after the week’s strong accumulation.

The week ending October 3 reported $3.24 billion in inflows, bringing the two-week total to $5.95 billion.

IBIT’s cumulative inflows reached $65.26 billion, accounting for over 100% of total category inflows when considering Grayscale GBTC’s historical outflows.

The fund’s consistent performance throughout the week drove the majority of the $2.71 billion weekly total.

Grayscale’s GBTC continued to face redemption pressure, with $19.21 million in daily outflows on October 10. The legacy fund reported 164.50 Bitcoin in daily redemptions, maintaining a cumulative net flow deficit of $24.20 billion since converting from a trust structure to an ETF.
