US-based spot Bitcoin exchange-traded funds (ETFs) have seen an impressive $4.26 billion in capital flows, recording 10 consecutive days of net inflows as of May 28. BlackRock’s iShares Bitcoin Trust (IBIT) is leading the rally. BlackRock’s IBIT Fund Sees Huge Interest: 10-Day Bitcoin ETF Inflows Surpass $4.2 Billion On Wednesday alone, Bitcoin ETFs saw $432.7 million in inflows, with nearly all of that coming from the IBIT fund alone, which attracted $481 million in inflows. On the other hand, Ark Invest's ARKB fund had a net outflow of $34.3 million, while Fidelity's FBTC fund had a net outflow of $14 million. There was no movement in the remaining funds. Of the net inflows in the 10-day period, 96% ($4.09 billion) were in the IBIT fund alone, with a total inflow of $45.6 billion across all funds since the launch of spot Bitcoin ETFs in January 2024. In comparison, IBIT has seen $49 billion in inflows since its launch, more than offsetting the $23.1 billion outflows in the high-fee Grayscale GBTC fund. IBIT has maintained its 33-day record of uninterrupted net inflows since April 9. During that time, only three days have closed with zero inflows. During those 33 days, the fund attracted $9.31 billion in inflows, bringing its assets under management to $72 billion. Nate Geraci, President of The ETF Store, said, “There were inflows in 30 of the last 31 days. $9.5 billion in new capital… IBIT announced that it will be among the top 5 inflow-receiving ETFs in 2025. Bloomberg ETF Analyst Eric Balchunas noted, “IBIT is currently the 23rd largest ETF at $72 billion. This fund is only 1 year old, while the other youngest ETF in the top 25 is 12 years old.” Spot Bitcoin ETF trading volumes also remain at their peak. With Bitcoin reaching an all-time high of $112,000 last week, weekly volume in ETFs has surpassed $25 billion. On Wednesday, May 28, ETFs traded a total of $3.4 billion. $2.6 billion of that came from the IBIT fund, which has a market share of nearly 80% in this metric. Meanwhile, spot Ethereum ETFs closed positive for the eighth consecutive day with net inflows of $84.9 million. BlackRock’s ETHA fund received $52.7 million, Fidelity’s FETH fund $25.7 million, Grayscale ETH $4.9 million, and Invesco QETH $1.6 million. The total trading volume of Ethereum ETFs was $446.9 million. The eight-day net inflow total reached $394.1 million. BlackRock’s IBIT fund is showing strong signs of continued institutional investor interest as it becomes a star not only in the Bitcoin ETF market but also in the general ETF league. *This is not investment advice.
