Spot Bitcoin ETFs Rake in $921M This Week—Wall Street Finally Wakes Up

Bitcoin ETFs just vacuumed up nearly a billion dollars in seven days—turns out even institutional investors FOMO when the price pumps. Who knew?

Behind the numbers: The SEC’s grudging approval of spot BTC ETFs earlier this year opened the floodgates for lazy capital. Now wealth managers can check their ’crypto exposure’ box without the hassle of actual custody—just in time for the halving rally.

The punchline? These same firms spent years calling Bitcoin a scam. Now they’re collecting 2% fees to hold it for boomers. Classic finance.

While BlackRock’s iShares Bitcoin Trust (IBIT) continues to dominate with a 19-day inflow streak that added more than $5 billion to its assets, Fidelity’s FBTC and ARK21Shares’ ARKB also clocked in huge numbers. This data comes from SoSoValue. 

Several macroeconomic and geopolitical factors have contributed to this inflow streak. The US struck a trade agreement with the UK and China, reducing global economic uncertainty and boosting investor confidence. Bitcoin broke above the $100,000 mark again, reaching around $104,000 and coming within 4.5% of its all-time high from January 2025.

However, in February 2025, BlackRock’s IBIT experienced its largest single-day outflow to date, with investors pulling out 5,000 BTC, equivalent to $420 million—on February 26. This surpassed the $332 million withdrawal recorded on 2 January 2025.

Speaking at the Token2049 Dubai on 30 April, Robert Mitchnick, Head of Digital Assets at BlackRock, had said, “The flows are back in a big way.” He further stated that seeing who was buying Bitcoin ETFs over the last 16 months was interesting. “At the outset, it certainly was predominantly retail. But then you also have the two other segments that are really important here, which is wealth advisory and institutional,” he explained.

Are Ethereum ETFs Nearing All Time Highs?

Inflows to ethereum ETFs were not as impressive as Bitcoin, but overall inflows are on an upward trajectory. ETH ETFs posted $1.5 million inflows, with AUM edging up to $12 billion.

Word on the street is that BlackRock is slowly shifting its focus towards Ethereum now. Notably, so far, BlackRock has only filed for 2 crypto ETFs, Bitcoin and Ethereum.
