Datadog delivered strong 36% revenue growth and a sharp improvement in profitability in Q2 FY2026, but its largest customer reducing usage and rising infrastructure costs pose challenges ahead.
Key risk: Reduction in Usage from Largest Customer
The company's largest customer, which is part of an AI-native cohort that contributed high single-digit percentage points to overall year-over-year revenue growth, began reducing usage starting Q3 FY2026. This could significantly decelerate revenue growth and harm financial performance if the trend continues or if other large customers follow suit.
