Datadog has a big-customer problem after a strong quarter
Datadog (DDOG) reported 35% revenue growth to $1.20 billion in Q3, but expects flat Q4 revenue due to reduced spending by a large AI customer. Morgan Stanley cut its price target to $270 from $300, citing volatility from AI-native customers. The company's forecast assumes the largest customer will pay the minimum contract amount, impacting growth estimates.
