Datadog 1Q26: Core Business Acceleration + AI-native Wins Validate Status Upgrade from Observability to AI

Core Thesis

Datadog delivered revenue growth acceleration to +32% YoY in 1Q26, well above consensus, and raised FY26 guidance by $240 million to imply +27% at the high end versus prior consensus of +20%. The narrative has shifted: AI is no longer a separate growth vector—it is invigorating the core business while simultaneously adding a hyper-growth AI-native customer cohort. We view Datadog’s status as elevating from observability leader to outright AI beneficiary, warranting a higher valuation multiple.

Market Mispricing: Core Strength and AI-native Gains Are Dual, Not Substitutive

The market may be underestimating two simultaneous growth engines. Core business (ex AI-natives) accelerated for a third consecutive quarter to mid-20% YoY, from +20% in 3Q25 and +23% in 4Q25. This is driven by AI initiatives fueling cloud migrations and digital transformation—not a separate AI-native segment. Meanwhile, AI-native customers continue ramping usage, including a large deal signed in 4Q25 that began contributing in Q1. The combination produced record net-new ARR and the strongest QoQ usage growth since 1Q22. The market may be pricing Datadog as an observability player trading at a premium to software, when the operating data suggests it now exhibits traits of an AI platform beneficiary.

Evidence Chain: Five Data Points Confirm Dual Acceleration

1. Top-line acceleration to +32% from +29% in 4Q25, approximately 5% above consensus. QoQ growth of +6% was the highest for a Q1 since 1Q22.

2. Record net-new ARR and record new-logo average deal size in the quarter, indicating both existing customer expansion and strong acquisition of high-value accounts.

3. Core business acceleration for three consecutive quarters: mid-20% in 1Q26, up from +23% in 4Q25 and +20% in 3Q25. This is the clearest signal that AI is stimulating broader cloud adoption, not just isolated AI-native workloads.

4. Two large AI research lab deals—one seven-figure and one eight-figure annualized—with AI research divisions at two of the world's largest technology companies. These did not materially contribute to 1Q results but will drive sequential dollar growth for the balance of 2026.

5. Guidance conservatism despite a $240 million FY26 raise. Management’s Q2 revenue guide of $1.07–$1.08 billion implies +29–31% YoY vs consensus of +20%, with QoQ growth of +6.9%—more than double the four-year average of +3.3%. FY26 guidance implies 2H26 growth slowing to +23% YoY, an assumption likely to prove conservative given core momentum, ramping AI-natives, and the new lab contracts.

Key Risks and Divergences

• Intensifying competition in observability and monitoring remains a structural risk. Crowded field includes Dynatrace, New Relic, and open-source alternatives. If large customers consolidate vendors or shift to cheaper alternatives, growth could decelerate faster than modeled.

• AI-native churn risk. Hyper-growth AI-native customers are inherently less predictable. If AI capex cycles moderate or OpenAI usage patterns change, the contribution from these customers could prove lumpy.

• Premium pricing pressure. Datadog’s pricing model could face pushback as customers seek to control observability costs. Any sign of weakening net revenue retention would challenge the premium valuation multiple.

• Guidance conservatism may mask underlying deceleration. While we view the 2H26 slowdown assumption as conservative, if macro headwinds or enterprise spending caution re-emerge, even the raised guidance could prove optimistic.

Valuation and Trading Implication

We raise the price target to $225 from $180, applying 53x CY28 free cash flow per share of $4.41 (2.2x growth-adjusted), discounted back one year. This implies 15x CY27 sales (0.6x growth-adjusted), a premium to the large-cap software median of 8x (0.4x growth-adjusted). We believe this premium is warranted given Datadog’s accelerating revenue, expanding margins (22.6% non-GAAP operating margin in 2026e, up from 22.4% in 2025), and status as an AI winner rather than an observability vendor. Our bull case of $300 assumes 28% revenue CAGR through CY28 with 27% operating margins, yielding $5.21 FCF per share.
