Datadog Shares Slide on Muted Revenue Outlook
The cloud monitoring company's fourth-quarter forecast matched expectations, but investors had hoped for a beat.
Updated on Nov. 4, 2026 in Economic Indicators
Datadog shares fell more than 17% in premarket trading after the company forecast fourth-quarter revenue of $1.19 billion to $1.2 billion. The shares had already dropped 21% in the five days before the report.
Why it matters
The sell-off came after a forecast that landed in line with analyst expectations rather than above them, showing how sharply the stock reacts when growth guidance fails to surprise. For U.S. investors holding cloud software stocks, the reaction highlights how much valuation depends on exceeding forecasts.
Datadog's third-quarter revenue reached $1.197 billion, up 35% from a year earlier, and the company counted 4,860 customers with annual recurring revenue of $100,000 or more, adding 140 since the second quarter. The forecast implies only about $3 million in growth from the third quarter at the high end, and it remains unclear how much of the slowdown reflects weaker usage among large customers.
The players
Datadog
Datadog is a cloud monitoring and security company whose software tracks the performance of applications and infrastructure running in cloud environments.
Amazon Web Services
Amazon Web Services is the cloud computing arm of Amazon and one of the largest cloud infrastructure providers, which both partners with and competes against Datadog.
The details
Datadog reported third-quarter revenue well above the high end of its forecast, yet the fourth-quarter outlook of $1.19 billion to $1.2 billion was only in line with analyst expectations. Shares had already fallen 21% in the five days before the report, and the in-line guidance was enough to push them down further in premarket trading.
Timeline
Five days before the report: Datadog shares fell 21%.

Market Dynamics
Datadog's reaction follows a pattern in which cloud software stocks priced for strong growth sell off when guidance only meets expectations. The move shows how the Federal Reserve-era rate environment and investor focus on growth durability continue to amplify swings in technology shares around earnings.
Investors holding Datadog or other cloud software shares face sharper price swings when guidance merely matches expectations, which can erode the value of positions bought on growth assumptions. Those tracking retirement accounts with technology exposure may see larger short-term fluctuations around earnings dates.
The takeaway
A forecast that meets expectations can still send a high-valuation stock lower when investors were hoping for upside. Watching whether revenue guidance beats or merely matches consensus helps explain many of the sharpest moves in growth stocks around earnings.
What happens next
Datadog's full fourth-quarter results and its earnings call commentary on core business growth and large-customer usage are the next key moments for investors to watch.
