US spot Bitcoin ETFs logged $171 million in outflows on Thursday, their biggest day of redemptions since March 3, when they posted $348 million in outflows.
Which funds saw the most selling
BlackRock’s IBIT led the outflows with $41 million, followed by Fidelity’s FBTC at $32 million, ARK 21Shares’ ARKB at $30.5 million, and Grayscale’s GBTC at $24 million, according to Farside Investors data.
Despite Thursday’s selling, US Bitcoin ETFs had attracted $1.36 billion in monthly inflows so far in March and were on track for their first month of net accumulation since October 2025, when they clocked $3.42 billion in net inflows.
Bitcoin fell below $70,000 on Thursday, trading at $67,780 at the time of writing — down 4.7% over the past week.
ETFs showing ‘incredible fortitude’
Senior Bloomberg ETF analyst Eric Balchunas noted the funds are just “one good day away” from reversing their year-to-date outflows, praising their resilience through bitcoin’s 46% correction from its $126,198 all-time high set in October 2025.
Balchunas stated:
“For context, when gold fell 40% in a short time frame about 10 years ago, it saw 1/3 of its investors bail.”
Iran war fears drive the selloff
The outflows came after reports that the US Department of War is sending thousands of soldiers to the Middle East.
On Thursday, President Trump announced a 10-day extension to the ceasefire on Iranian energy infrastructure through April 6, citing ongoing negotiations.
Despite the extension, investors remained on edge. Kyle Rodda, senior financial analyst at Capital.com, told Cointelegraph:
“Amidst the headline risk and he-said, she-said games about whether negotiations between the US and Iran are taking place, the US is moving assets and personnel towards the Middle East to prepare for what looks like a limited ground invasion.”
Rodda added that investors were caught off guard by the initial US and Israeli strikes on Iran on Feb. 28, which occurred in the middle of what appeared to be constructive negotiations, leaving markets jittery about any repeat surprise.
