U.S. Bitcoin ETFs Maintain Five-Week Inflow Streak
Bitcoin exchange-traded funds in the U.S. continue to attract investor attention, registering over $600 million in inflows across the past week.
Despite a rocky start to Q2, these crypto investment vehicles have now notched five straight weeks of net capital inflow — a sign that institutional appetite for BTC exposure remains resilient, even as the pace of inflows begins to cool.
Data from Farside Investors reveals that Friday, May 16, was the strongest day of the week, with spot Bitcoin ETFs pulling in $260 million in a single session. That marked the third consecutive day of gains after mid-week withdrawals temporarily disrupted the flow.
Leading the charge was BlackRock’s iShares Bitcoin Trust (IBIT), which alone absorbed nearly $130 million. Fidelity’s Wise Origin Bitcoin Fund (FBTC) followed with almost $68 million, while ARK and 21Shares’ jointly managed fund (ARKB) saw just under $58 million. Grayscale’s newer offering, the Bitcoin Mini Trust, added $4.6 million.
Although the total inflow for the week remained positive, it was noticeably lower than the boom seen in April, when ETFs posted more than $3 billion in just five days. The last time U.S. Bitcoin ETFs crossed the $1 billion weekly mark was at the end of April, with $1.8 billion pouring in.
The sustained but tapering interest suggests that while enthusiasm hasn’t vanished, investors may be growing more cautious after several weeks of aggressive accumulation.

It started in 2016 with Bitcoin. Like most people at the time, he didn't fully understand it - so he kept digging. Blockchain, tokenomics, the projects, the cycles. That curiosity never stopped, and eventually pulled him into traditional markets too: equities, commodities, macro. Not because he left crypto behind, but because you can't properly understand one without the other. What drives him is straightforward: he wants to know why something is happening, not just that it's happening. Most market coverage stops at the headline - price up, price down, here's a chart. Alex finds that kind of reporting actively unhelpful. If you walk away from an article without understanding the mechanism behind the move, what did you actually learn? He holds a degree in Tourism from New Bulgarian University - not the most obvious path into financial markets, but markets have a way of pulling in people who are simply too curious to stay out. He has authored over 200 in-depth analyses and more than 10,000 articles across crypto and traditional finance. He still thinks every day in markets teaches him something new. That's probably why he hasn't stopped.
