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

U.S. spot Bitcoin ETFs saw the largest divestment over the past three weeks on March 26, with net outflows of more than $170 million in a single day. Even Ark Invest—an investment firm that has long supported cryptocurrencies—also substantially reduced its holdings of the Bitcoin ETF it co-issues with 21Shares on the same day, selling nearly 500,000 shares worth about $11.2 million.

According to SoSoValue data, U.S. spot Bitcoin ETFs recorded net outflows of $171.2 million on Thursday, the highest single-day outflow since March 6. BlackRock’s IBIT led with $41.9 million in outflows, while funds from Fidelity, Bitwise, and Ark also saw outflows of more than $30 million each.

Analyst: Taking profits in the short term, not a shift in long-term confidence Nick Ruck, director of research at LVRG, analyzed that this wave of capital outflows reflects short-term profit-taking, risk-averse moves amid macroeconomic uncertainty, and capital rotation when the market is choppy—not a major change in long-term investment confidence.

Nick Ruck noted that institutional investors still maintain a cautious but optimistic stance toward crypto. On one hand, interest in Bitcoin remains strongly on the rise; on the other hand, institutions are gradually accepting tokenized traditional assets. He explained that institutional sentiment is mainly driven by macroeconomic factors, including the U.S.-Iran conflict and the ensuing global oil supply shortage.

Meanwhile, Ethereum spot ETFs also recorded net outflows of $92.5 million on Thursday, marking the seventh consecutive trading day of withdrawals and the longest period of net outflows since December 2025.

Ark cuts its own Bitcoin ETF holdings As institutional capital repositions, Ark Invest—led by Cathie Wood—cut its holdings in its ARK 21Shares Bitcoin ETF (ARKB) by 495,000 shares on Thursday, worth about $11.2 million.

On the same day, Ark also trimmed multiple crypto-related stocks, including selling $6.7 million worth of Bullish stock and about $5.1 million worth of Block stock. These moves were in line with the broader sell pressure across technology stocks that day, including Alphabet, Nvidia (NVIDIA), and Meta, all of which were also reduced.
