A rapidly growing tech stock just joined the world’s most widely followed stock market index. If previous additions to the S&P 500 are any indication, this could help drive substantial gains for the company’s shareholders going forward.
Many investors around the world view the S&P 500 as a bellwether of the U.S. economy, and gaining a spot among its constituents is typically seen as validation of a company’s scale and stability and investors’ perception of a stock as a prospective portfolio candidate.

Datadog (DDOG) , a leading cloud-native monitoring and analytics platform, officially became the latest member of the S&P 500 Index effective July 9, 2025.
The tech company replaced previous S&P 500 stock Juniper Networks, following the completion of its acquisition by Hewlett Packard Enterprise earlier this month.
Shares of Datadog surged nearly 15% on July 3 after S&P Global announced its impending addition to the S&P 500. The news sparked a fresh wave of investor interest, given the anticipation of increased near-term demand from both retail and institutional investors, especially among passive index funds, which will be forced to rebalance to reflect Datadog’s inclusion.
Previous S&P 500 additions have preceded significant gains for the companies’ respective shareholders; as of this writing, Palantir stock is up 275% since joining the index last September, DoorDash is up 25% since being added in March, and Coinbase shares have climbed 47% since joining the S&P 500 in May.
Shares of Datadog are up around 9% over the past year, slightly underperforming the S&P 500’s 11.5% gain over the same period.

Datadog’s inclusion in the S&P 500 highlights the growing role that data monitoring, security, and artificial intelligence tools play in today’s technology landscape. Tech companies comprise over a third of the S&P 500’s total value.
It also helps punctuate Datadog’s impressive growth story; founded in 2010 and public since 2019, Datadog now serves over 30,500 customers globally, including nearly half of the companies in the S&P 500. Datadog’s revenue for the trailing 12 months ending March 31, 2025, grew 26% year over year to $2.8 billion.
