How ‘absurd’ momentum drives BlackRock’s Bitcoin ETF toward $100B

Key Takeaways 

Why is BlackRock’s $100B Bitcoin ETF target unique? 

IBIT is set to reach $100 billion AUM in under 450 days — faster than any ETF in history.

What’s the impact of BlackRock’s IBIT on BTC price? 

It has led to strong ETF inflows, fueling a spot-market demand that could further rally BTC. 

BlackRock’s iShares Bitcoin [BTC] Trust ETF (IBIT) has smashed records and is now on track to hit $100 billion assets under management (AUM) milestone.

It will become the fastest ETF to hit that target and currently the most profitable product across the BlackRock ETF lineup. 

With less than a two-year-old, IBIT’s explosive growth is “absurd”, according to Bloomberg ETF analyst Eric Balchunas. In fact, IBIT raked in $244 million in annual revenue based on the press time AUM of $97.8 billion.

$50B added to AUM in 2025

In 2024, IBIT closed the year with $51 billion in AUM. At the time, the average BTC price was approximately $93,000.

Although the Q1 2025 headwinds and tariff wars dragged AUM to $47 billion, it has rebounded to over $97 billion as of October. That’s about $50 billion added this year.

If this pace of ETF inflows continues for the rest of Q4, IBIT could cross the $100 billion mark by October. 

Reacting to IBIT’s growth, ETF Store founder Nate Geraci added that the leading ETF took five years to cross $100 billion.

“World’s largest ETF, Vanguard S&P 500 ETF, took 2,000+ days to hit that mark. IBIT is about to do it in < 450 days. Easily fastest ever.”

Bitcoin ETFs dominate inflows as Ethereum lags

That being said, the overall BTC ETFs inflows rebound in H2, led by IBIT, have surpassed collective Ethereum [ETH] ETF inflows. 

According to CryptoQuant, in the last 30 days, BTC ETFs absorbed $4.61 billion in inflows while ETH ETFs lagged behind with $1.05 billion.

CryptoQuant analyst JA Maartunn noted that the shift implied a likely rotation from ETH to BTC.

The shift could stall the ETH/BTC rally seen in Q3.

Meanwhile, the strong BTC ETFs and Spot market demand lifted BTC price to a new all-time high $126.1K. At press time, however, it had slipped slightly below $124K. 

With key liquidity pools at $118K, $120K, and above $127K to $130K, these could be key price targets to watch in the near term.
