Vanguard’s S&P 500 ETF, VOO, has become the first exchange-traded fund to surpass $1 trillion in assets under management, marking a significant milestone for the ETF industry and underscoring the continued growth of passive investing, according to Financial Times.
The fund crossed the $1 trillion threshold on June 3, having quadrupled in size since 2022. The achievement comes as investors continue to pour money into low-cost index-tracking products and seek exposure to large-cap U.S. stocks that have benefited from the artificial intelligence boom.
VOO has also overtaken State Street’s SPDR S&P 500 ETF Trust (SPY) as the largest ETF in the world. The fund’s rapid growth has been supported by strong market performance, substantial investor inflows, and Vanguard’s low-cost structure. VOO charges an expense ratio of 0.03%, making it one of the least expensive ways for investors to gain exposure to the S&P 500 Index.
The milestone reflects the broader expansion of the global ETF market. Exchange-traded funds worldwide held nearly $22 trillion in assets as of the end of April, more than tripling from approximately $6.4 trillion at the beginning of 2020. The industry has also experienced more than six consecutive years of monthly net inflows.
The rise of large index-tracking ETFs has been fueled by investor migration away from actively managed funds and toward passive investment strategies. Many investors have embraced low-cost index funds as a way to participate in long-term market growth while avoiding higher management fees.
The growing scale of ETFs could also have implications for upcoming public offerings. With major companies such as SpaceX, Anthropic, and OpenAI reportedly considering or preparing for public market debuts, index funds and ETFs tracking major benchmarks could become significant buyers of newly listed shares once those companies qualify for inclusion in major indexes.
Industry observers note that recent discussions among index providers regarding faster index inclusion rules could further accelerate demand for shares of newly public companies. If adopted, proposed changes could reduce the waiting period before a stock becomes eligible for inclusion in the S&P 500, increasing the speed at which passive investment vehicles allocate capital to new entrants.
VOO’s success also underscores the importance of costs in investor decision-making. While competing S&P 500 ETFs offer similar exposure, Vanguard’s combination of scale, liquidity, and low fees has helped attract tens of billions of dollars in new assets.
The ETF is part of Vanguard’s unique structure that allows ETF and mutual fund share classes to operate within the same underlying fund. Together, the ETF and its companion mutual fund share class now hold approximately $1.6 trillion in assets, making it one of the largest investment vehicles in the world.
The milestone further cements Vanguard’s position as a leader in passive investing and demonstrates the growing influence of ETFs on global capital markets.
