Vanguard Overtakes iShares as Largest ETF Provider

The ETF industry has reached a historic turning point. Vanguard has officially surpassed BlackRock’s iShares to become the largest ETF provider in the U.S. The milestone underscores a broader structural shift among investors prioritizing low-cost investments in portfolio allocations.

Key Takeaways

• Vanguard has overtaken BlackRock’s iShares as the leading ETF issuer, driven by monumental differences in recent asset flows.
• The shift follows the Vanguard S&P 500 ETF (VOO) becoming the first ETF to cross the $1 trillion assets under management milestone.
• Vanguard’s relentless fee cuts, including reductions across 53 funds earlier this year, continue to attract capital.

iShares and Vanguard ETF Inflow Disparities Drive the Switch

BlackRock recorded a healthy $131 billion in year-to-date inflows and $418 billion over the past year; however, it was not enough to keep pace with Vanguard. Vanguard captured a staggering $278 billion in year-to-date net inflows and $546 billion over the past 12 months, according to VettaFi data.

“Vanguard has long been known for creating low-cost, diversified strategies with broad appeal across investor types,” Roxanna Islam, head of sector and industry research at VettaFi, said. “Many retail investors, in particular, use these products as long-term core portfolio holdings, which helps support steady asset growth over time.”

The Road to $1 Trillion

This historic industry flip follows a key milestone last year when the Vanguard S&P 500 ETF (VOO) surpassed the State Street SPDR S&P 500 ETF Trust (SPY) as the largest ETF. VOO recently made history as the first ETF to cross $1 trillion in assets under management. Currently, VOO sits at $1 trillion in total assets, comfortably ahead of the iShares Core S&P 500 ETF (IVV) at $818 billion and SPY at $777 billion.

Vanguard’s ETF market footprint is massive. The issuer now commands six of the top 10 largest ETFs in the industry:

 

Leading the firm’s charge this year are VOO with $101 billion in year-to-date inflows, VTI with $28 billion, the Vanguard Total International Stock ETF (VXUS) with $16 billion, and BND with $13.4 billion.

Unrelenting Fee Reductions Pay Off

Vanguard has built a legacy of making investing more accessible, affordable, and efficient for investors over the past five decades. Earlier this year, Vanguard slashed fees on 53 different funds, delivering an estimated $250 million in savings for 2026 alone. This brought the firm’s two-year total savings to approximately $600 million, the largest two-year combined cost reduction in its five-decade history.

100% of Vanguard’s active fixed-income funds and 89% of its fixed-income ETFs were priced in the lowest cost decile of their respective categories as of February. 

Furthermore, low costs have translated to reliable performance, with 84% of Vanguard funds outperforming peer group averages over the past decade as of February. This outperformance rises to 88% within the active fixed-income suite when measured against benchmarks.

Looking ahead, Vanguard is continuing to expand its ecosystem. The firm bolstered its fixed-income lineup this month with the launch of the Vanguard U.S. High-Yield Corporate Bond Index ETF (VCHY), offering advisors an ultra-low-cost vehicle to target below-investment-grade corporate debt.
