BlackRock’s Bitcoin ETF Is About to Smash $100 Billion — And It’s Reshaping Wall Street

A Record-Breaking Rise

In just over a year, BlackRock’s iShares Bitcoin Trust (IBIT) has done what few thought possible: it’s on the brink of $100 billion in assets, a milestone reached by only a handful of ETFs in history.

As of Monday, IBIT managed $99.4 billion, putting it within inches of joining the ultra-exclusive $100B club. Since debuting on January 11, 2024, the fund has obliterated growth records — sprinting past $20B, $50B, and $80B in lightning succession to become the fastest-growing ETF ever launched.

For context: it took the Vanguard S&P 500 ETF (VOO) nearly eight years to achieve the same feat.

IBIT Rules the Crypto ETF Market

IBIT isn’t just growing — it’s dominating. The fund now holds about half of all assets across U.S. spot cryptocurrency ETFs. Its closest rivals, Fidelity’s Wise Origin Bitcoin Fund (FBTC) and Grayscale’s Bitcoin Trust (GBTC), sit far behind with $26.1 billion and $22.2 billion in AUM.

So far in 2025, the numbers tell a one-sided story:

- IBIT inflows: +$26.4B

- FBTC inflows: +$1.0B

- GBTC outflows: –$2.6B

Add in its sibling fund, the iShares Ethereum Trust (ETHA), and BlackRock’s crypto duo have absorbed nearly all $38 billion of new money flowing into the entire U.S. spot crypto ETF market this year.

In effect, IBIT has become the default gateway for mainstream investors seeking exposure to Bitcoin — simple, regulated, and traded just like any stock.

Riding Bitcoin’s Meteoric Rally

IBIT’s explosive growth is being powered by both inflows and the unrelenting strength of Bitcoin itself. The cryptocurrency recently surged above $125,000, climbing roughly 160% since IBIT’s launch.

About two-thirds of IBIT’s asset growth comes from new investor money, with the rest driven by price appreciation. At its current scale, the fund now represents around 4.2% of Bitcoin’s $2.4 trillion market cap, giving it enough heft to subtly sway price trends and liquidity dynamics across the crypto market.

In other words, IBIT isn’t just tracking Bitcoin — it’s shaping it.

How Big Could It Get?

IBIT’s ascent has prompted speculation about its future scale. If Bitcoin’s total market value climbed to $3 trillion and IBIT maintained a 10% share, its AUM would hit $300 billion.

In a more bullish case — say, a $5 trillion Bitcoin market with a 20% share — the ETF could reach a staggering $1 trillion in size.

Those figures remain hypothetical, but they underscore a shift that’s already real: crypto investing has gone mainstream, and ETFs are driving the transition.

Joining the ETF Elite

Crossing the $100 billion mark would place IBIT in rarefied air. Only 18 U.S.-listed ETFs currently sit above that line, nearly all of them tracking major stock indexes such as SPY and VOO.

What’s remarkable is the speed. In just 18 months, IBIT will have done what took legacy index giants almost a decade — a sign that digital assets are no longer a fringe play, but a full-fledged piece of Wall Street’s core portfolio.
