While Bitcoin’s price has recently rebounded, the enthusiasm for spot ETFs appears to be cooling. Weekly inflows into U.S. Bitcoin ETFs have dropped sharply, signaling a pause in aggressive institutional accumulation.
For the week ending May 8, total net inflows fell to just $599 million, down from $1.81 billion the previous week and well below the late-April surge of $3 billion. This marks the weakest inflow since mid-April, despite Bitcoin hovering around its highs.
Yet the pullback hasn’t dented overall fund growth. Thanks to price appreciation, total assets held across all Bitcoin ETFs have now reached $121.2 billion—up nearly $8 billion in just one week. BlackRock’s IBIT remains dominant, accounting for more than half that figure with $64.4 billion in assets and leading daily inflows with $356 million on May 9.
Other notable players include Fidelity’s FBTC at $20.5 billion and Grayscale’s GBTC at $19.4 billion, though GBTC continues to see outflows. Meanwhile, cumulative ETF inflows since launch have reached $41 billion, suggesting new capital still makes up a sizable chunk of the total.
Trading activity also cooled last week. Weekly turnover dropped to $9.27 billion, down from $13.2 billion, indicating reduced short-term positioning. Still, daily flows remained strong, with $2.67 billion in volume on May 9 alone.
Despite the slowdown in weekly inflows, the overall trend remains upward. With price gains pushing ETF valuations higher and new money continuing to trickle in, the institutional presence in Bitcoin remains firmly intact.
