“Missing Forest-for-the-Trees”: Datadog Sinks 17% in a Week as Its Biggest AI Customer Cuts Back
Datadog (DDOG) stock fell 17% in a week after reporting 35% Q3 revenue growth to $1.2B but guiding Q4 revenue to $1.19-1.2B, roughly flat. The decline was driven by its largest AI customer reducing usage, though growth outside this customer is accelerating. Cloudflare (NET) reported strong Q3 results and a rising Q4 outlook, suggesting the slowdown may be isolated. Datadog trades at 60x forward earnings, below its usual multiple.
