Shares of Datadog (DDOG Quick QuoteDDOG - Free Report) have surged 64.6% year to date, outperforming the broader Zacks Computer and Technology sector's growth of 15.5%, as the AI-powered observability and security platform continues to convert enterprise AI adoption into accelerating revenues.

Yet even after this sharp climb, the investment case for Datadog is not about chasing momentum. It rests on a set of fundamental drivers — expanding large-customer relationships, deepening AI-native product adoption, and a raised full-year outlook — that suggest the stock is best treated as a hold for existing shareholders rather than a fresh buy or a name to exit.

Investors already positioned in DDOG have good reason to stay put, while those still on the sidelines may be better served waiting for a more attractive entry point, given how much of the good news is already reflected in the price.

AI Product Momentum Is Broadening the Platform

Datadog advanced its AI roadmap with the general availability of Bits Code, Bits Chat and Bits Agent Builder, extending its Bits AI suite toward fully autonomous incident detection, investigation and remediation. It also introduced AI Guard, a capability built to protect AI agents from prompt injection and data-poisoning attacks, addressing a security gap opening up as enterprises push more agentic workloads into production. Datadog additionally completed its acquisition of Adaptive ML, a frontier AI reinforcement-learning specialist, and was named a Leader in the Gartner Magic Quadrant for Observability Platforms for the sixth consecutive year. Together, these moves reinforce a widening platform rather than a single-product story, supporting the hold thesis even as the stock digests its year-to-date gains.

Customer Growth Remains Broad-Based, Not AI-Only

Datadog's own disclosures point to genuinely durable demand across its full customer base rather than a narrow, AI-only bump. Management has highlighted that revenue growth among non-AI-native customers also accelerated meaningfully in the most recent quarter, indicating that core cloud-migration and modernization spend remains healthy alongside AI workloads. On the client-win front, the company reported roughly 4,720 customers with annual recurring revenues of $100,000 or more as of quarter-end, up 23% year over year, alongside a record sequential revenue increase of $115 million. That breadth across large accounts and everyday cloud customers reduces reliance on any single buyer cohort.

Raised Guidance Signals Management Confidence

Datadog's own forward guidance, issued alongside its second-quarter 2026 results on Aug. 6, 2026, offers a more grounded, fundamentals-based read on near-term prospects than the stock chart alone does. For the third quarter of 2026, the company guided revenues to a range of $1.135 billion to $1.145 billion and non-GAAP operating income of $260 million to $270 million. For the full year, management raised its outlook to revenues of $4.45 billion to $4.47 billion, non-GAAP operating income of $1.01 billion to $1.03 billion, and non-GAAP earnings per share of $2.50 to $2.54. Notably, this guidance was raised even after factoring in a usage reduction from the company's largest customer, a sign that demand elsewhere in the customer base is more than offsetting that single account's pullback.

The Zacks Consensus Estimate for DDOG's 2026 earnings currently stands at $2.52 per share, up 4.6% over the past 30 days, compared with earnings of $2.05 per share reported in 2025. That said, the customer-concentration episode is a useful reminder that usage-based revenues can still swing with individual account behavior, a nuance that argues for patience rather than aggressive buying at current price levels.

Valuation and Competitive Landscape

From a valuation perspective, DDOG appears overvalued, trading at a forward price-to-sales ratio of 15.73, well above the Zacks Internet – Software industry average of 3.98, and the company carries a Value Score of F.

Datadog competes against a mix of legacy technology giants and specialized observability players, including International Business Machines (IBM Quick QuoteIBM - Free Report) , Cisco Systems (CSCO Quick QuoteCSCO - Free Report) and Dynatrace Software (DT Quick QuoteDT - Free Report) . IBM brings scale and deep enterprise relationships, Cisco leverages its networking footprint, and Dynatrace competes directly on AI-driven automation. Against IBM's and Cisco's broader portfolios and Dynatrace's narrower observability focus, Datadog's platform breadth remains a differentiator, even as IBM, Cisco and Dynatrace intensify AI-native monitoring investment.

Investors may still hold despite the premium valuation because accelerating large-customer growth and raised full-year guidance suggest fundamentals are catching up to the multiple. Holding through the run is reasonable too, since the gains largely reflect improving operating leverage and cash-flow growth rather than sentiment.

Conclusion

Datadog's fundamentals, broadening AI product adoption, resilient large-customer growth and an upwardly revised full-year outlook paint a picture of a durable, expanding platform rather than a stock riding a temporary wave. At the same time, a stretched valuation, a soft Value Score and lingering customer-concentration risk argue against adding aggressively after such a steep run. For current shareholders, the balance of evidence favors holding and letting the underlying business continue to compound its growth through disciplined execution; for prospective buyers watching from the sidelines, waiting patiently for a calmer, more attractive entry point remains the more prudent near-term path forward. Datadog stock currently carries a Zacks Rank #3 (Hold). You can see the complete list of today’s Zacks #1 Rank (Strong Buy) stocks here.
