Q: Datadog just posted four consecutive quarters of accelerating growth. Is this the best-run company in software right now?

A: By most operating measures, yes. First-quarter revenue grew 32% year over year to just over $1 billion, up from 25% a year earlier, while free cash flow held a 29% margin and annual recurring revenue crossed $4 billion. The acceleration was not limited to AI-native customers: revenue excluding that cohort grew in the mid-20% range, up from 19% a year earlier, evidence this is a broad adoption cycle rather than a handful of frontier-lab contracts.

Q: So why isn’t this a straightforward Buy?

A: Price. The shares have compounded 134% since the March low and now trade at 19.5 times guided 2026 revenue and roughly 70 times estimated free cash flow. Every intrinsic valuation method, including a ten-year discounted cash flow model, lands between $145 and $202. Only relative multiples support today’s $246.86 — the signature of a re-rating driven by the multiple rather than the cash flow. A scenario-weighted fair value lands near $239, about 3% below the current price.

Q: What’s the single biggest risk?

A: Concentration in one account. A single customer, widely believed to be OpenAI, represented roughly 10 to 12% of revenue. Datadog builds extra conservatism into guidance around this account, which is good discipline but also a tell. The business also bills on usage, so a cost-optimization push across customers can shrink revenue immediately without a renewal event, as happened in 2023 when net revenue retention fell to around 111%.

Q: Is the growth durable, or borrowed from AI hype?

A: Genuinely durable in large part. Roughly 85% of revenue is still non-AI, gross retention sits in the mid-to-high 90s, and 20% of customers now use eight or more of Datadog’s 26 products, up from 13% a year ago. The moat is real, built on workflow lock-in rather than raw technology.

Q: What would change the call to Buy?

A: A pullback into the $185-215 range, or confirmation in the August 6 earnings report that the largest customer renewed with growth while non-AI-native growth holds in the mid-20s%.

Q: So what’s the verdict?

A: Watchlist, not Buy. This is a wonderful business trading at a price that already assumes nearly everything goes right. Existing holders have reason to hold and trim into strength; new buyers are better served waiting for the accumulation zone.
