Facebook, Inc. (FB) has established itself as the leading social media giant. In 2020, Facebook generated more than $85.90 billion in revenue and $29.20 billion in net income or profit.

When Facebook issued its initial public offering (IPO) on May 18, 2012, many mutual funds had already snapped up shares on the private market. A mutual fund is an investment vehicle that contains a basket of securities or stocks.

Although Facebook's stock price has gone on a roller-coaster ride, the mutual funds that held the stock benefited from its high growth rate. It is important to note that these funds have ownership of the Facebook Class A shares and not the Class B shares, which carry heavier voting rights.

For investors looking for exposure to Facebook through the company's equity shares, below are the top mutual holders of Facebook's stock.

1. The Vanguard Total Stock Market Index Fund Admiral Shares (VTSAX)

Facebook's largest mutual fund holder is the Vanguard Total Stock Market Index Fund Admiral Shares (VTSAX), which has approximately $1.2 trillion in assets under management. Vanguard's VTSAX owns nearly 68 million shares of Facebook with a market value of more than $22 billion as of April 30, 2021.

The VTSAX is designed to offer broad exposure to the total U.S. stock market and has an expense ratio of 0.04% and a five-year annualized return of 17.67% as of April 30, 2021. The fund has a $3,000 minimum investment requirement.

For those who are unable to meet the $3,000 initial investment, Vanguard offers an exchange traded fund (ETF) called the Vanguard Total Stock Market ETF (VTI). The ETF is similar to the VTSAX but has a lower initial investment requirement, which is the price of one share.

2. The Vanguard 500 Index Fund Admiral Shares (VFIAX)

Facebook's second-largest mutual fund holder is the Vanguard 500 Index Fund Admiral Shares (VFIAX), which owns nearly 49.50 million shares of the social media giant with a market value of approximately $16.10 billion as of April 30, 2021.
