BlackRock’s Bitcoin ETF Nears $100 Billion After Outperforming 25-Year-Old S&P 500 Fund

• BlackRock’s IBIT hits $244.5 million annual revenue, nearing $100 billion assets faster than any ETF.
• Bitcoin ETFs saw $3.2 billion inflows last week, with IBIT taking $1.78 billion amid a price surge past $125,000.

BlackRock’s iShares Bitcoin Trust ETF (IBIT) has become the top-performing fund by annual revenue, reaching $244.5 million. The ETF has surpassed long-standing funds, including the Core S&P 500 ETF (IVV), which has been in operation for 25 years and holds nearly seven times more assets.

This outcome highlights the sharp rise in institutional demand for regulated Bitcoin exposure as the cryptocurrency continues to set new records. IBIT charges a 0.25% management fee on its total assets, which currently stand at $97.8 billion.

Bloomberg senior ETF analyst Eric Balchunas noted on X that BlackRock’s $IBIT is now its most profitable fund, nearing $100 billion in assets under management.

He shared a chart showing the fastest ETFs to reach that mark, pointing out that Vanguard’s $VOO holds the current record at 2,011 days, while IBIT is on track to do so in just 450 days. He said, 

Bitcoin ETF Growth Accelerates in October

The surge in IBIT’s growth comes during a record-breaking period for Bitcoin and related ETFs.  In the past week, Bitcoin ETFs brought in $3.2 billion in net inflows, the second-highest amount ever and the strongest week of 2025 so far. Of that total, $1.78 billion flowed directly into IBIT, showing its lead among spot Bitcoin products.

On October 6, the total net inflows in Bitcoin ETFs reached $1.19 billion, the biggest one-day increase this year. Data from SoSoValue shows that BlackRock’s fund accounted for $969.95 million of that amount,  further reinforcing its dominant position.

In the first six days of October, inflows rose to $2.29 billion, which is close to September’s full-month total of $3.53 billion. If this pace continues, this month could become one of the record-breaking months for Bitcoin ETFs.

BlackRock Eyes Bitcoin Income ETF Amid Market Rally

The rise in Bitcoin’s price has increased investors’ excitement. Over the weekend, the cryptocurrency crossed the $125,000 mark and even went above $126,000 for a short time. It has now settled at around $123,826, showing an 8.67% gain over the past week.

The broader pro-crypto stance in Washington has also played a role. The Trump administration openly aimed to make the United States the “crypto capital of the world.” This goal increased investors’ confidence and encouraged greater participation from traditional financial institutions.

At the same time, BlackRock has expanded its crypto strategy. The company recently filed in Delaware to launch a Bitcoin Premium Income ETF. This fund aims to generate income by selling option contracts on Bitcoin futures.This product would differ from IBIT, which directly tracks Bitcoin’s actual price.

Balchunas observed that the filing indicates BlackRock’s focus remains on Bitcoin- and Ethereum-related products, instead of branching into smaller altcoin ETFs.

However, progress on several pending crypto ETF applications has been delayed after the U.S. SEC paused its review process due to the ongoing federal government shutdown.
