BlackRock’s Bitcoin fund hits $70B faster than any ETF in history

• BlackRock’s IBIT became the fastest ETF to surpass $70 billion AUM in just 341 days.
• IBIT held 661,000+ BTC, making it the largest institutional Bitcoin holder globally.

BlackRock’s spot Bitcoin [BTC] ETF has made history by becoming the fastest exchange-traded fund to exceed $70 billion in assets under management.

The milestone reflects broader market confidence and positions BlackRock’s offering as a potential game-changer in the evolution of crypto investment products.

Analyst appreciates BlackRock’s IBIT growth

Remarking on the same, Eric Balchunas took to X (formerly Twitter) and noted, 

“IBIT just blew through $70B and is now the fastest ETF to ever hit that mark in only 341 days.”

Balchunas also highlighted that BlackRock’s IBIT is surpassing expectations, reaching $70 billion in assets under management nearly five times faster than SPDR Gold Shares (GLD)—the previous record-holder.

While GLD took over 1,600 trading days to achieve the milestone, BlackRock’s IBIT accomplished it in a fraction of the time, reinforcing its explosive market entry.

That being said, since its 2024 debut, the ETF has secured over $9 billion in inflows in 2025 alone, earning a spot among the top five U.S. ETFs.

This coincided with BlackRock recently acquiring 2,704 Bitcoins valued at roughly $283.9 million, along with 28,239 Ethereum [ETH] tokens worth an estimated $73.2 million.

Institutions jumping into IBIT

This rise in BlackRock’s prominence is also being reflected in the number of institutions joining the list of embracing IBIT.

For instance, the Moscow Stock Exchange has listed Bitcoin Futures tied to IBIT.

Additionally, JPMorgan has also planned to roll out ETF-backed loans, beginning with BlackRock’s flagship crypto fund, indicating growing confidence and utility in Bitcoin-focused investment products.

Hence, with over 661,000 BTC under management, BlackRock’s IBIT has officially become the largest institutional holder of Bitcoin, surpassing both Binance and Michael Saylor’s Strategy.

What’s more?

Currently valued at $71.9 billion, the ETF’s meteoric rise has also positioned it to potentially overtake even Satoshi Nakamoto’s estimated holdings by next summer, according to Bloomberg’s Eric Balchunas.

Therefore, as IBIT shares trade near $62 and Bitcoin crosses the $110,000 mark, the ETF continues to dominate its peers, securing nearly $49 billion in net inflows since its 2024 debut.

As expected, this trajectory paints IBIT as the most influential player among spot Bitcoin ETFs in the U.S. market.
