In recent crypto news, Blackrock Bitcoin ETF has become the highest grossing instrument for the world’s largest asset manager.
The fund, iShares Bitcoin Trust (IBIT), launched in January 2024, and in less than two years, it grew faster than any ETF in history.
IBIT reached $70 billion in assets in just 341 days. Even after Bitcoin’s price fell, it stayed strong. IBIT is now BlackRock’s most profitable product. Wall Street has quickly embraced cryptocurrency.
Blackrock IBIT Goes From Zero to $70 Billion in Record Time
IBIT started small but grew fast. In its first week, it held $1 billion. By the end of 2024, it reached $70 billion. That was the fastest any ETF had ever grown.
By July 2025, IBIT managed $75 billion. In October, it crossed $98 billion and briefly touched $100 billion. At its peak, it held more than 700,000 bitcoins.
Then Bitcoin’s price fell from $125,000 to $91,000. IBIT’s assets dropped to $70.8 billion. Even so, no ETF in history has grown this quickly.
Why Blackrock IBIT Earns More Than Older Giants
BlackRock runs more than 1,400 ETFs. It’s famous iShares Core S&P 500 ETF (IVV) manages $624 billion, but it charges only 0.03% in fees. That brings in about $187 million a year.
IBIT, by contrast, charges 0.25%, eight times higher. At $98 billion in assets, that fee generated around $245 million annually.
That’s more than IVV, more than the Russell 1000 Growth ETF, and more than any other BlackRock fund.
Together with BlackRock’s Ethereum ETF, crypto funds now bring in about $260 million a year.
Analysts say the combination of Bitcoin’s high price and strong demand makes the simple fee structure extremely powerful.
What Happens Next After the Recent Drop
November 2025 was a tough month for financial markets. Bitcoin lost more than 25% from its all-time high, and investors pulled $2.34 billion out of IBIT in just a few weeks.
BlackRock executive Cristiano Castro said this is normal for liquid ETFs, which allow investors to move money quickly.
Despite the outflows, big institutions are still buying. For instance, Harvard University’s endowment owns $443 million worth of IBIT.
BlackRock’s own bond funds added 14% more shares in the last quarter. Many experts believe money will return quickly if Bitcoin climbs again.
Many analysts predict that IBIT could become a multi-billion-dollar revenue machine if Bitcoin reaches $200,000 or more.
For BlackRock, the bet on Bitcoin has already changed the company forever. A product that did not exist two years ago is now its top profit center.
That shows how fast Wall Street has embraced cryptocurrency. Even after a sharp price drop, IBIT remains the most profitable ETF BlackRock has ever launched.
Its rise from zero to $100 billion in record time is a milestone not just for the company, but for the entire ETF industry.
Crypto has gone from the edges of finance to the heart of Wall Street. And BlackRock’s Bitcoin ETF is leading the way.
