- Bitcoin ETFs saw $3.2 billion in net inflows during October 2025.

In under two years, BlackRock’s iShares Bitcoin Trust ETF (IBIT) has become the company’s most profitable exchange-traded fund (ETF), surpassing the 25-year-old Core S&P 500 ETF (IVV) in annual revenue. This rapid success comes as demand for regulated cryptocurrency products, particularly Bitcoin exposure, grows amid Bitcoin’s record-breaking price rally. With nearly $100 billion in assets under management, IBIT’s swift growth has set new standards for the industry.
Rapid Growth of IBIT
The iShares Bitcoin Trust ETF, launched less than two years ago, has already earned $244.5 million in annual revenue. This performance surpasses even long-standing and much larger ETFs, including BlackRock’s Core S&P 500 ETF, which manages assets significantly larger than IBIT. BlackRock charges a 0.25% management fee on IBIT’s assets under management (AUM), which currently stands at $97.8 billion, putting the fund on track to reach $100 billion in the near future.
Comparing IBIT’s rapid growth to other large ETFs demonstrates its impressive performance. The Vanguard S&P 500 ETF (VOO), for instance, took over 2,000 days to reach $100 billion in AUM, whereas IBIT is expected to accomplish this milestone in fewer than 450 days. This difference in growth rates highlights the growing interest in Bitcoin ETFs and the role IBIT plays in this trend.
Bitcoin ETF Surge Amid Record Price Rallies
IBIT’s growth is closely linked to Bitcoin’s performance in the market. Bitcoin has experienced significant price rallies, including reaching new all-time highs, which have contributed to the surge in demand for Bitcoin ETFs. During what has been referred to as “Uptober,” Bitcoin ETFs saw $3.2 billion in net inflows, with IBIT accounting for a significant portion of this total, attracting $1.78 billion.
October 6 marked a record day for Bitcoin ETFs, with $1.19 billion in net inflows recorded in a single day. BlackRock’s IBIT captured nearly $970 million of that total, further solidifying its dominance in the sector. The overall strong performance of Bitcoin, trading at approximately $124,569, up nearly 9% in just a week, continues to drive institutional interest and inflows into Bitcoin-related financial products.
Comparing IBIT with Other Major ETFs
IBIT’s rapid rise in profitability and assets has sparked comparisons with other prominent ETFs. As mentioned, IBIT reached near $100 billion in AUM in under two years, a milestone that took much longer for other ETFs, such as the Vanguard S&P 500 ETF. The S&P 500 ETF, which has been active since 1993, took over five years longer to reach the $100 billion mark.
Nate Geraci, a well-known ETF expert, pointed out that IBIT is on track to reach this milestone in less than 450 days. He noted that IBIT’s growth is not only faster but is also a sign of the broader shift toward cryptocurrency products, which are gaining increasing mainstream acceptance.
Institutional Interest and Record Inflows
The Bitcoin ETF market continues to see substantial institutional interest. Bitcoin ETFs collectively saw record inflows, driven by both strong market momentum and the broader appeal of digital assets. BlackRock’s IBIT, with its focus on regulated crypto exposure, has become a key player in this market.
IBIT’s dominance is further illustrated by its share of Bitcoin ETF inflows. The $3.2 billion in net inflows recorded recently marked the largest weekly inflow of 2025, with IBIT capturing the majority of it. As Bitcoin’s price continues to soar, more investors are turning to regulated investment vehicles like IBIT to gain exposure to Bitcoin’s price movements while mitigating some of the risks associated with direct ownership of the cryptocurrency.
BlackRock’s ability to quickly capitalize on the growing demand for Bitcoin ETFs and surpass long-standing funds in profitability highlights the changing dynamics of the ETF market.
