BlackRock Bitcoin ETF Now 23rd Among Largest ETFs, Balchunas Says Next Youngest ETF in Top 25 is 12yrs Old

The BlackRock Bitcoin ETF has emerged as one of the most aggressively growing ETFs in the market, registering billions in net inflows over the past month. 

This achievement has pushed BlackRock’s iShares Bitcoin Trust (IBIT) to the 23rd position among the largest ETFs globally, with its total assets under management (AUM) now standing at $72.4 billion. 

BlackRock Bitcoin ETF Secures $9B in a Month

Nate Geraci, president of the ETF Store, brought attention to this impressive development, noting that IBIT has recorded inflows on 29 of the past 30 trading days, along with a 32-day streak without any outflows. Within this period, the product saw $9 billion in netflows.

Geraci mentioned how the ETF’s momentum has far exceeded early expectations. At the time of its launch, some industry watchers believed the entire spot Bitcoin ETF category might not exceed $10 billion in AUM. Yet, IBIT alone has now nearly matched that initial cap in net inflows in just one month.

Notably, data from Sosovalue confirms that IBIT’s consistent inflows began on April 14, when it attracted $36.72 million in net investments. Since then, it has experienced daily net inflows except May 13, when it recorded zero flows. 

Several significant intraday netflow surges contributed to the $9 billion milestone during this period. Specifically, on April 23, IBIT brought in $643.16 million in a single day. Five days later, on April 28, the ETF witnessed its highest single-day inflow of the year at $970.93 million. 

Interestingly, Bitcoin’s price on April 28 only showed a modest increase of 1.36%, closing at $95,000, indicating that institutional appetite for exposure to Bitcoin via the BlackRock Bitcoin ETF remained strong irrespective of the price action.

Meanwhile, the momentum continued into May. On May 2, the ETF drew in another $674.91 million. Later in the month, on May 22, it recorded an inflow of $877.18 million, outpacing VOO, the largest ETF by AUM. Most recently, on May 27, IBIT attracted an additional $409.26 million in net inflows, leading to the $72.4 billion in total assets.

IBIT Now 23rd Among Largest ETFs

Reacting to the impressive performance, Bloomberg senior ETF analyst Eric Balchunas spotlighted IBIT’s stunning rise. He highlighted that IBIT’s current AUM of $72 billion places it among the top 25 largest ETFs in the world, specifically at the 23rd position. 

$IBIT on fire lately, now has $72b in assets, which ranks it 23rd overall, absolutely bonkers for a one year old. The next youngest ETF in the Top 25 is 12yrs old! https://t.co/i62HDtbyxJ

He also pointed out the extraordinary nature of this achievement given that the BlackRock Bitcoin ETF is only a year old. The next youngest ETF within the top 25 is the iShares Core MSCI Emerging Markets ETF (IEMG), which launched back in October 2012. 

With its current AUM, the BlackRock Bitcoin ETF has now surpassed the Invesco S&P 500 Equal Weight ETF (RSP), which holds $72.1 billion in assets. 

However, IBIT still has significant ground to cover to break into the top 10 ETFs. To reach that milestone, it would need to exceed the Vanguard Total Bond Market ETF (BND), which currently ranks 10th with $126.8 billion in AUM. This means IBIT would require an additional $54.6 billion in net assets to secure a top-10 position.
