Vanguard Market Share Slips as BlackRock and Fidelity Gain
Vanguard’s market share in U.S. mutual funds and ETFs is declining after nearly five decades of steady growth. Bloomberg ETF analyst Eric Balchunas said Vanguard’s share has plateaued at about 27%, while Morningstar reported that its share among the 150 largest fund families fell by roughly one percentage point in 2025.
Vanguard held about 28% of total U.S. fund assets at the end of 2024. Vanguard, BlackRock and Fidelity still controlled around 50% of the market, highlighting the industry’s concentration. Morningstar said part of Vanguard’s decline resulted from assets moving from traditional funds into collective investment trusts, rather than investors leaving the firm outright.
The shift reflects the long-term “Vanguard Effect”. Vanguard’s low-cost index funds pushed competitors to reduce fees and helped make passive investing mainstream. The firm now reports an asset-weighted average expense ratio of 0.06% and manages more than $11 trillion in U.S.-domiciled mutual funds and ETFs. It controls about 44% of passive fund assets. Its VOO ETF recently surpassed $1 trillion in assets.
BlackRock has expanded through its iShares ETF business and model portfolios, while Fidelity has gained through active funds, retirement accounts and money-market products. The data suggest that Vanguard remains a dominant passive-investing provider, but competitors are capturing growth through broader product ranges and investment services.
Neutral
The market impact is neutral because the article concerns competition and asset flows in traditional U.S. funds, not a direct change in cryptocurrency demand, regulation or liquidity. Vanguard’s declining market share could attract attention from traders because the firm remains a major institutional investor and its fee reductions reinforce the broader shift toward low-cost passive products. However, there is no evidence that the change will materially alter Bitcoin or other digital-asset flows in the short term.
For traditional markets, the news may support continued competition among ETF providers and pressure expense ratios lower. It could also benefit BlackRock and Fidelity if investors favor their broader product ranges. Short-term crypto trading reactions are likely to be limited and driven mainly by broader risk sentiment, interest-rate expectations and ETF-flow data. Over the long term, the expansion of low-cost ETFs and institutional investment platforms could improve familiarity with exchange-traded products, potentially supporting digital-asset adoption if crypto products are included in those platforms. Similar historical developments, such as fee wars among index-fund providers, have generally produced gradual structural changes rather than sharp market moves.
