Dell and Palantir both saw their shares jump about 7% in after-hours trading on Friday following the announcement from S&P Global that they will be added to the S&P 500 index. Palantir will replace American Airlines, while Dell will take the place of Etsy in the benchmark index.
This move marks Dell’s return to the S&P 500, having been a member from 1996 to 2013 before going private and rejoining the public market in 2018. For Palantir, which went public in 2020 after over 15 years as a venture-backed startup, this inclusion highlights its recent profitability and growing revenue. The company reported a net income of $135.6 million for the second quarter, a significant increase from the previous year.
The inclusion of these companies reflects their high market capitalizations—Palantir’s exceeds $67 billion, while Dell’s is over $72 billion—matching the median market cap of S&P 500 companies at approximately $33.5 billion. The addition often leads to a rally in stock prices as index-tracking funds adjust their portfolios to include the new members.
Dell’s stock had already surged 90% in 2023, driven by strong demand for AI servers. Meanwhile, Palantir, known for its data analytics and work with government and military agencies, has seen accelerated revenue growth and posted its first profits in late 2022.
The S&P 500 additions are intended to better represent U.S. stocks with high market caps. The inclusion of these companies follows recent changes, such as the addition of cybersecurity firm CrowdStrike in June. Shares of software maker Workday fell 2% in after-hours trading, despite earlier speculation about its potential inclusion in the index.
