Of that, an impressive $2.83 billion flowed into BlackRock’s IBIT in just six trading days, indicating the fund’s role as the main driver of institutional demand. Notably, the BlackRock ETF continues to follow the pattern of consistent buying even as competitors hesitate.

Arkham Intelligence said that on one recent trading day, BlackRock reported nearly $900 million in inflows, while other ETFs, apart from Valkyrie, recorded little to no purchases, and Grayscale’s GBTC actually saw net selling.

Why BlackRock Buys When Others Sell

As per Arkham, BlackRock’s brand reputation inspires confidence among institutional investors seeking a regulated and trusted vehicle for Bitcoin exposure.

1 – BlackRock’s brand image and reputation attracts flows for Bitcoin, which has accelerated their IBIT ETF to almost $100B AUM.

Secondly, its low management fee of 0.25%, compared to GBTC’s 1.5%, has triggered a steady migration of assets from older products into IBIT.

Third, differences in reporting schedules may occasionally make BlackRock’s inflows appear higher, as it could be reporting activity on a T+1 basis, a day later than its peers.

IBIT Becomes BlackRock’s Fastest-Growing ETF

Less than two years after launch, IBIT has accumulated nearly $98 billion in assets under management, making it one of BlackRock’s fastest-growing and most profitable ETFs.

Bloomberg’s senior ETF analyst Eric Balchunas reported that IBIT now generates around $244.5 million in annual revenue, surpassing several of BlackRock’s flagship products such as the iShares Russell 1000 Growth ETF (IWF) and the iShares MSCI EAFE ETF (EFA). Both of these long-established funds earn roughly $219 million annually.

If IBIT maintains its current trajectory, it could become the fastest ETF in history to surpass $100 billion AUM, leaving behind the growth pace of the Vanguard S&P 500 ETF (VOO), which took over five years to reach that mark.
