These Are the 3 Most Widely Owned Exchange-Traded Funds (ETFs) by Retail Investors - And Why They’re Dominating Portfolios in 2025
Retail investors are flocking to these three ETF giants—betting big on market trends while Wall Street still tries to figure out what 'democratized finance' actually means.
The Top Contenders
Three funds stand out from the crowd, capturing the majority of retail investment flows. Their dominance isn't accidental—each taps into specific market sentiments that resonate with everyday traders.
Why These ETFs?
Accessibility meets strategy. These products offer instant diversification without the headache of picking individual stocks—perfect for investors who want exposure without the PhD in financial analysis.
The Retail Revolution
Main Street isn't waiting for permission anymore. While traditional finance debates fee structures, retail investors are voting with their dollars—and the results are shaking up the entire industry.
Just remember: when everyone piles into the same three funds, someone's definitely left holding the bag when the music stops.

Retail investors are gravitating to ETFs
Based on a study ("The Retail Investor Report") published by the University of Missouri – Kansas City School of Law from five authors, retail investors were responsible for almost 25% of equities trading volume on Wall Street in 2021, which nearly doubled where things stood a decade prior. Online brokers have taken note of this and are catering their platforms to court everyday investors.
The broker that's arguably had the most success luring retail investors is(HOOD -0.76%). Robinhood's platform offers commission-free trades for stocks on major U.S. exchanges, as well as the ability to purchase fractional shares of stock.
What's also noteworthy about Robinhood is its public "100 Most Popular" leaderboard, which displays the 100 most-held securities across its platform. Though retail investors undeniably favor high-profile companies and the occasional meme stock, you'd be surprised at how popular exchange-traded funds (ETFs) are.
ETF's typically hold a basket of securities and allow investors to diversify or concentrate their portfolios with the click of a button based on a laundry list of factors, which can include company size, growth versus value, or industry, to name a few. In exchange for this convenience, investors pay a fee, known as the net expense ratio, which represents the cumulative fees paid by investors that cover management/marketing expenses.
Three of the 10 most held securities on Robinhood by retail investors are ETFs, as of Sept. 9.
No.'s 1 and No. 2: Vanguard S&P 500 ETF and SPDR S&P 500 ETF Trust
The sixth and ninth most held securities by everyday investors on Robinhood are, respectively, the(VOO 0.32%) and(SPY 0.32%). These are both index funds that attempt to mirror the performance of the benchmark(^GSPC 0.30%).
Every year, the analysts at Crestmont Research refresh a data set that calculates the 20-year rolling total returns, including dividends, of the S&P 500 since the start of the 20th century. Even though the S&P wasn't officially incepted until 1923, researchers were able to track the total return of its components in other major indexes from 1900 to 1923.
What Crestmont's analysis showed is that all 106 rolling 20-year periods it examined (1900-1919, 1901-1920, and so on, through 2005-2024) generated a positive annualized total return. Hypothetically speaking, because the first S&P 500 tracking fund didn't exist until 1993, if an investor had purchased an S&P 500 index fund at any point between 1900 and 2005 and held for 20 years, they WOULD have generated a hearty profit every time. This is the closest thing you'll get to a guarantee on Wall Street -- and retail investors know it!
Although the Vanguard S&P 500 ETF and SPDR S&P 500 ETF Trust serve the same purpose, there is one noticeable difference between the two: their net expense ratios.
Index funds usually sport relatively low net expense ratios, and these two are no exception. However, the Vanguard S&P 500 ETF's net expense ratio of 0.03% is a third of the SPDR S&P 500 ETF Trust's 0.09%. A difference of six hundredths might not sound like much, but over multiple decades, or when dealing with a large investment, it can add up quickly. Only $0.30 of every $1,000 invested goes toward fees with the Vanguard S&P 500 ETF.

No. 3 Vanguard FTSE Developed Markets ETF
The third ETF that lands among the 10 most held securities on Robinhood by retail investors is the(VEA 0.07%). It's the 10th most-popular holding, right behind the SPDR S&P 500 ETF Trust.
The Vanguard FTSE Developed Markets ETF attempts to track the performance of the. In simpler terms, it's an investment vehicle that gives buyers exposure to large-, mid-, and small-cap companies located in Europe, Canada, and the Pacific region, not including the United States. It's delivered a nearly 4% annualized return since its inception in July 2007 (i.e., just before the Great Recession).
To keep with the theme, its net expense ratio is absolutely a lure. The Vanguard FTSE Developed Markets ETF matches the Vanguard S&P 500 ETF with a net expense ratio of just 0.03%. Investors are giving up very little of their capital for the convenience of closely mirroring the performance of this fund's underlying index. In comparison, similar funds have average expense ratios of 0.86%.
Another attractive aspect of the Vanguard FTSE Developed Markets ETF is its relative valuation compared to U.S. stocks. The S&P 500's Shiller price-to-earnings (P/E) Ratio shows this is the third-priciest stock market when back-tested over 150 years.
In comparison, the P/E ratio of the more than 3,800 companies that comprise the Vanguard FTSE Developed Markets ETF was a more reasonable 16.3 on July 31. If you expect international stocks to outperform U.S. stocks for the foreseeable future, this is a smart ETF to consider buying.
