BlackRock’s iShares franchise has crossed the $5 trillion mark in global assets under management, cementing its status as the world’s largest ETF issuer. That milestone means iShares alone accounts for about 29% of the $17.7 trillion global ETF market.

The firm projects that industrywide ETF assets could nearly double within five years. If iShares maintains its current market share, that would put the brand on track to manage more than $10 trillion in the coming years.

In announcing the milestone, BlackRock highlighted several growth areas. iShares’ bond ETF lineup now tops $1 trillion in assets, with an estimated 40% market share. Its cryptocurrency funds have gathered roughly $100 billion, led by the iShares Bitcoin Trust (IBIT) with $81 billion and the iShares Ethereum Trust (ETHA) with $16 billion.

The firm has also aggressively expanded into active ETFs, where assets now total $78 billion across more than 100 products worldwide. The largest include the iShares U.S. Equity Factor Rotation Active ETF (DYNF), at $22 billion, and the iShares Flexible Income Active ETF (BINC), at $11.6 billion.

Most of iShares’ assets reside in the U.S., where it manages $3.7 trillion, or about 30% of the $12.2 trillion U.S. ETF market. Its lineup includes some of the world’s largest funds, such as the $660 billion iShares Core S&P 500 ETF (IVV), the $149 billion iShares Core MSCI EAFE ETF (IEFA), and the $131 billion iShares Core U.S. Aggregate Bond ETF (AGG).

The largest iShares fund outside the U.S. is the iShares Core S&P 500 UCITS ETF (CSPX), which manages $125 billion and is listed in markets across Europe, Latin America, and the Middle East. The $116 billion iShares Core MSCI World UCITS ETF (SWDA) is the second-largest.

Vanguard remains the No.2 ETF issuer globally, with $3.9 trillion in assets, more than a trillion behind iShares.
