The Fortune 500, in its 70th year in 2024, ranks the biggest U.S. companies by revenue.

These innovative companies are laying the foundations for robust growth—and outsize returns for shareholders.

Founded in 2004, Arista became a leader in cloud networking at a time when bigger rivals were slow to seize that opportunity. Some investors have worried that the Santa Clara, Calif.–based company has been too dependent on a handful of huge clients (including Meta and Microsoft); Arista’s recent moves to diversify its client base and expand into data warehousing have eased those concerns somewhat. Analysts expect the company to generate $5.9 billion in revenue this year, up 34% from 2022. Arista has been led since 2008 by Jayshree Ullal, one of three female CEOs on this year’s Future 50.
