Bitcoin ETF bleeds $170 million in a single day, reaching a three-week high! Ark has also reduced its holdings in its own ETF.

On March 26, the U.S. spot Bitcoin ETF experienced the largest outflow of funds in the past three weeks, with a net capital outflow of over $170 million in a single day. Even Ark Invest, which has traditionally supported cryptocurrencies, significantly reduced its holdings in the Bitcoin ETF jointly issued with 21Shares on the same day, selling nearly 500,000 shares worth about $11.2 million.
According to SoSoValue statistics, the U.S. Bitcoin spot ETF recorded a net outflow of $171.2 million on Thursday, marking the highest single-day loss since March 6. Notably, BlackRock’s IBIT led the outflows with $41.9 million, while Fidelity, Bitwise, and Ark’s funds also saw outflows exceeding $30 million each.
Analyst: Short-term profit-taking, not long-term confidence wavers
LVRG Research Director Nick Ruck analyzed that this wave of capital outflow reflects short-term profit-taking, hedging operations under overall economic uncertainty, and capital rotation during market turbulence, rather than a significant shift in long-term investment confidence.
Nick Ruck pointed out that institutional investors remain cautiously optimistic about cryptocurrencies, with sustained interest in Bitcoin and a gradual acceptance of tokenized traditional assets. He explained that institutional sentiment is mainly influenced by macroeconomic factors, including the U.S.-Iran war and the resulting global oil shortage.
On the other hand, the Ethereum spot ETF also recorded a net outflow of $92.5 million on Thursday, marking the seventh consecutive trading day of outflows, setting the longest loss record since December 2025.
Ark reduces holdings in its Bitcoin ETF
As institutional funds reposition, Ark Invest, led by Cathie Wood, reduced its holdings in the ARK 21Shares Bitcoin ETF (ARKB) by a total of 495,000 shares, worth approximately $11.2 million.
On the same day, Ark also reduced its holdings in several cryptocurrency-related stocks, including selling $6.7 million of Bullish shares and about $5.1 million of Block shares. These actions coincided with the general selling pressure in tech stocks that day, including reductions in holdings of Alphabet, NVIDIA, and Meta.
