Summary
US spot Bitcoin ETFs experienced a significant two-day outflow cycle that partially unwound recent momentum, with investors redeeming $166.8 million across the first two trading sessions of a holiday-shortened week ending September 10, 2026. According to Farside Investors, Wednesday alone saw $120.2 million in net outflows, following $46.6 million in redemptions on Tuesday. This marked the funds' first consecutive negative flow days since a three-day outflow run concluded on August 14.
The withdrawal pattern was concentrated among the largest Bitcoin ETF issuers. ARK 21Shares Bitcoin ETF led the exodus with $78 million in Wednesday outflows, representing significant institutional repositioning. Grayscale's Bitcoin Trust ETF contributed $27.2 million in redemptions, while BlackRock's iShares Bitcoin Trust shed $19.5 million. Morgan Stanley's Bitcoin Trust was the sole fund bucking the trend, recording $4.5 million in inflows. Across the two-session period, Grayscale's fund accumulated the largest total redemption volume at $92.7 million, followed by ARK 21Shares with $69.9 million and BlackRock with $8.8 million.
The pullback erased approximately 4.4% of the $3.8 billion in net inflows generated during Bitcoin ETFs' strongest three-week run of 2026, indicating profit-taking after an extended accumulation phase. Despite the week's redemptions, Bitcoin ETFs have attracted approximately $55 billion in cumulative net inflows since their respective launches. However, 2026 year-to-date flows reflect broader institutional uncertainty, with the fund category recording net outflows of approximately $1.07 billion through early September.
In contrast to Bitcoin ETF weakness, cryptocurrency-adjacent products demonstrated mixed but improving momentum. US spot Ether ETFs reversed Tuesday's $24.3 million outflow, posting $34.7 million in inflows Wednesday, with BlackRock's ETHB leading the category at $22.9 million. Spot Solana ETFs similarly rebounded, attracting $11.2 million on Wednesday after a $700,000 outflow on Tuesday, with all inflows concentrated in Bitwise's BSOL fund. These secondary cryptocurrency ETF categories combined for $10.5 million in net inflows over the two-session period, suggesting selective institutional demand remained present despite broader Bitcoin fund redemptions.
