BlackRock’s IBIT Bitcoin ETF Climbs to Fourth in 2025 ETF Inflows

BlackRock’s spot Bitcoin ETF, known as IBIT, has soared to become the fourth-largest ETF in the U.S. for year-to-date inflows in 2025, according to Bloomberg analyst Eric Balchunas. This is a significant leap from just three months ago when the fund was ranked 47th. Now, IBIT has surpassed well-established ETFs like the SPDR Portfolio S&P 500 ETF (SPLG), and it’s closing in on major names such as the Vanguard Total Stock Market ETF (VTI) and the iShares 0-3 Month Treasury Bond ETF (SGOV).

As of now, IBIT has attracted approximately $13.7 billion in new capital this year. It trails SGOV at $19.7 billion, VTI at $19.3 billion, and remains far behind the leading Vanguard S&P 500 ETF (VOO), which has seen a massive $82 billion in 2025 inflows.

Balchunas noted on X (formerly Twitter), “$IBIT has moved into 4th place on the YTD ETF inflow leaderboard, overtaking $SPLG. Even more remarkable is that it now ranks 5th in 3-year inflows, despite existing for just 1.5 years.”

The ETF has also recorded nine consecutive days of inflows—more than any other Bitcoin ETF during the same period. On June 17 alone, IBIT saw a single-day inflow of $639.2 million. That week ended with a net gain of $46.9 million.

Between June 4 and June 20, IBIT added over $2.6 billion, according to Farside Investors. Other notable inflow days included $336.7 million on June 10, $288.3 million on June 12, and $278.9 million on June 18. These consistent gains enabled IBIT to outperform competitors such as Fidelity’s FBTC and Ark Invest’s ARKB, both of which experienced net outflows during several of those days.

Data from Arkham Intelligence shows that BlackRock’s crypto ETFs have now exceeded $72 billion in total assets under management. Since launching its Bitcoin (IBIT) and Ethereum (ETHA) ETFs, BlackRock has led the industry in crypto ETF inflows.
