Vanguard’s S&P 500 ETF (VOO) has made history by becoming the first exchange-traded fund to surpass $1 trillion in assets, a milestone that highlights the relentless growth of passive investing and the powerful influence of the artificial intelligence rally. The fund crossed the threshold on Wednesday after quadrupling in size since 2022, as investors poured record sums into low-cost vehicles offering broad exposure to US equities.
The AI boom has been a primary catalyst. “As investors chase the AI boom, ETFs have become an ultimate vehicle for US equity exposure,” said Todd Rosenbluth, head of research at TMX VettaFi. VOO charges an annual fee of just 0.03%, matching BlackRock’s IVV, while State Street’s SPY costs 0.0945% – a difference that has driven massive inflows into Vanguard’s fund. VOO attracted more than $60 billion in new money this year alone, underscoring how even tiny fee differences sway institutional and model portfolio allocations.
The achievement also spotlights the looming wave of mega IPOs expected to further bloat passive vehicles. SpaceX is preparing to list on Nasdaq under ticker SPCX, aiming to raise $75 billion at a $1.77 trillion valuation. Anthropic and OpenAI are also eyeing public debuts with trillion-dollar-plus valuations. Proposed “fast entry” rules by S&P Dow Jones Indices would cut the waiting period for index inclusion from 12 to six months, compelling passive funds to buy shares at potentially inflated post-IPO prices. As Rob Arnott of Research Affiliates noted, “The narrative is: buy the IPO price, no matter what, and sell after the S&P adds it.”
Globally, ETFs now hold $21.9 trillion in assets, up from $6.4 trillion in early 2020, and have recorded 83 consecutive months of net inflows. The passive investing juggernaut shows no signs of slowing, with BlackRock’s IVV seen as the only credible challenger to VOO’s dominance. For the crypto market, the relentless appetite for risk assets and technology themes could spill over positively, reinforcing the correlation between equity and digital asset sentiment.
