Spot Bitcoin ETFs saw record trading activity in March 2026, with four of their highest-volume days occurring during the month. The total net assets for these ETFs approached $91 billion, representing approximately 6.4% of Bitcoin’s total market value. Despite the high trading volumes, recent data indicates a mixed sentiment with notable daily net outflows.
Spot Bitcoin exchange-traded funds had some of their busiest trading days ever in March 2026. Data shared by market intelligence firm Santiment revealed that March 2 recorded the highest volume at $31.6 billion. February 23 saw $23.2 billion, while March 18 and March 19 recorded $21.4 billion and $21.1 billion respectively.
Flow data suggests sentiment is mixed despite the surge in trading activity. Figures show Bitcoin spot ETFs saw a daily net outflow of about $90 million on March 19, part of a short-term pullback after earlier inflows. Total net assets are close to $91 billion, which is about 6.4% of Bitcoin’s market value.
BlackRock‘s IBIT and Fidelity‘s FBTC recorded the largest daily outflows recently, with about 544 BTC and 370 BTC exiting. The divergence suggests investors are repositioning rather than adding exposure, even though participation is high. Analyst Axel Adler Jr. pointed out that Bitcoin ETF holders are currently underwater, with their realized price standing at just under $80,000.
Adler stated that the profit gap could influence investor behavior if prices get near the $80,000 level. Despite the situation, the total number of ETF holdings increased by more than 26,000 BTC in the last few weeks after February outflows. Bitcoin briefly dipped below $70,000 for the first time in a week recently but had bounced back slightly.
It is down about 1.6% over seven days but gained around 4% in the past month. Bitcoin’s dominance moved up slightly from yesterday’s 56.3% to about 56.5% as it asserts itself over altcoins. Santiment analysts believe ETF trading volumes may stay high as investors adjust positions in response to macro and crypto-specific changes.
