Datadog's (DDOG) is officially stepping into the major leagues.
On July 9, the cloud observability and security software firm will join the S&P 500, replacing Juniper Networks following its acquisition by Hewlett Packard Enterprise. The move caps a major milestone in Datadog's relatively young public life—and investors wasted no time cheering the news.
DDOG Joins the Big League
Shares of Datadog surged nearly 12% following the S&P Dow Jones Indices announcement. The company’s inclusion in the index not only enhances its visibility but also triggers a wave of buying from index-tracking funds and ETFs that collectively manage trillions of dollars. For a stock already riding the momentum of a strong earnings beat in May, this catalyst offers fresh validation of its long-term positioning.
Founded in 2010 and public since 2019, Datadog provides a unified dashboard for monitoring servers, applications, databases, and cloud infrastructure. With a market capitalization now exceeding $50 billion, Datadog's S&P 500 debut underscores the broader transition from legacy IT hardware toward cloud-native, SaaS-based models in enterprise computing.
Passive Inflows and Market Validation Drive Stock Higher
The index shakeup comes after Hewlett Packard Enterprise (HPE) completed its $14 billion acquisition of Juniper Networks (JNPR), freeing up a spot in the S&P 500. While other candidates, including Robinhood, had been floated as possible replacements, Datadog's profitability, scale, and growth trajectory sealed its selection.

Inclusion in the S&P 500 carries tangible financial implications. Passive funds such as the SPDR S&P 500 ETF (SPY), which oversees more than $630 billion in assets, must now buy DDOG shares. Historically, index inclusions spark price bumps of 5% to 15% in the short term due to this mechanical demand. For Datadog, the move has already reversed a year-to-date decline and brought it into positive territory for 2025.
Strong Financials and Strategic Positioning Cement Growth Outlook
Datadog isn’t just riding the passive investment wave—it’s earning its place. The company’s first-quarter revenue jumped 25% year-over-year to $761.6 million, beating expectations, while non-GAAP earnings per share also topped forecasts. The company now serves around 30,500 customers, with nearly 3,800 generating over $100,000 in annual recurring revenue—a 13% increase in high-value clients.
Enterprise adoption remains strong, with half of the Fortune 500 using Datadog’s services. Its suite of observability tools continues to expand through acquisitions and AI integrations, bolstering its appeal amid rising demand for cloud-native performance and security solutions.
Despite its premium valuation—trading at roughly 13 times sales versus an S&P 500 average of 3—investors appear willing to pay for profitable growth in a high-margin, expanding market. Analysts’ consensus price targets range broadly, but most see meaningful upside, with some estimates implying gains north of 30%.
Conclusion
Datadog's ascension to the S&P 500 is more than a ceremonial nod—it’s a clear signal that cloud-native software is no longer the future; it’s the now. As legacy players exit and next-gen leaders enter, DDOG stands at the forefront of this transformation. With solid financials, strong enterprise demand, and newfound index legitimacy, Datadog's trajectory points firmly upward..
