Datadog's Slowing Outlook Weighs on Stock Despite Strong AI Demand

Strong Earnings Meet Cautious Growth Expectations

Datadog (DDOG) shares fell approximately 14% Wednesday after the cloud-monitoring and security company issued a fourth-quarter outlook that disappointed investors despite reporting stronger-than-expected third-quarter results.

Revenue increased 35% year over year, supported by continued adoption of cloud and artificial intelligence services. However, the company's largest customer is reducing its usage, raising concerns about near-term growth and the sustainability of its recent momentum.

Key Points

• Strong quarterly performance: Third-quarter revenue rose 35% to approximately $1.2 billion, while adjusted earnings of $0.81 per share exceeded Wall Street expectations.
• Slower growth ahead: Fourth-quarter revenue guidance of $1.19 billion to $1.20 billion implies little sequential growth, partly reflecting reduced usage from Datadog's largest customer.
• Margins face pressure: Management expects fourth-quarter adjusted operating margin to decline to approximately 24% from 28% in the third quarter, despite continued growth in large customers and AI adoption.

Strong Third-Quarter Results Fail to Support Datadog Stock

Datadog delivered third-quarter revenue of approximately $1.2 billion, exceeding Wall Street expectations of roughly $1.14 billion. Adjusted earnings reached $0.81 per share, compared with analysts' estimates of $0.64. Adjusted operating income increased to $334 million, representing a 28% operating margin, up from 23% a year earlier.

Customer expansion also remained healthy. Datadog ended the quarter with approximately 4,860 customers generating at least $100,000 in annual recurring revenue, an increase of 20% from the previous year. The company generated $251 million in free cash flow, although its free cash flow margin declined to 21% from 24% a year earlier. Management also raised its full-year revenue outlook to approximately $4.52 billion, implying annual growth of roughly 32%.

Despite these results, investors focused on the company's weaker near-term guidance rather than its quarterly earnings performance.

Why Did Datadog Stock Fall After Beating Expectations?

The primary concern was Datadog's fourth-quarter revenue forecast of $1.19 billion to $1.20 billion, essentially unchanged from the third quarter. Although that outlook still represents approximately 25% to 26% year-over-year growth, it signals a meaningful slowdown from the third quarter's 35% increase.

Management attributed part of the pressure to reduced consumption from its largest customer, an undisclosed artificial intelligence company. Chief Financial Officer David Obstler said the fourth-quarter forecast assumes that customer will reduce its usage to its minimum contractual commitment. The slowdown is particularly significant because Datadog has benefited from expanding AI workloads and increasing demand for infrastructure monitoring.

The company also expects fourth-quarter adjusted operating income of $280 million to $290 million, below the third quarter's $334 million. That implies an operating margin of approximately 24%, compared with 28% in the previous quarter.

The market reaction also reflected elevated expectations. Datadog shares had risen approximately 62% during 2026 through Tuesday's close, leaving investors focused on whether the company could sustain its rapid growth into 2027. Morgan Stanley analysts identified continued revenue growth of approximately 30%, excluding Datadog's largest customer, as a central question for the company's longer-term outlook.

AI Adoption and Customer Expansion Remain Important Growth Drivers

Despite the slowdown associated with its largest customer, Datadog reported continued strength across its broader customer base. Revenue growth from non-AI customers accelerated for the fifth consecutive quarter, while its AI customer base continued expanding and diversifying. CEO Olivier Pomel said customers are increasingly adopting Datadog's platform as they expand their digital operations and deploy more AI-powered applications. The company is also developing specialized AI models intended to help businesses manage increasingly complex technology environments and automate operational tasks.

Still, the fourth-quarter outlook has raised questions about whether it reflects a broader slowdown in cloud spending or a more concentrated customer issue. Competitor Dynatrace (DT) reported 17% revenue growth in its latest quarter and provided a higher sequential revenue forecast for the following period. Cloudflare (NET), another company exposed to cloud infrastructure demand, is scheduled to report earnings Thursday. Those results could provide additional context for cloud and AI-related spending trends, although Datadog's customer-specific challenges do not establish a broader industry slowdown.

What It Means for Investors

Datadog's earnings reaction highlights the distinction between strong current performance and expectations for future growth. The company continues to report substantial revenue expansion and healthy demand for its monitoring platform, but reduced consumption from its largest customer introduces uncertainty into its near-term outlook, and the projected decline in operating margin raises questions about how efficiently it can sustain growth as its business expands.

Investors will be watching whether fourth-quarter revenue exceeds management's guidance, whether consumption trends stabilize, and whether growth outside the largest customer remains strong. The company's eventual 2027 outlook will also be important in assessing whether its recent growth rates can be sustained.

Conclusion

Datadog's cautious fourth-quarter outlook and anticipated margin compression overshadowed a strong third quarter, contributing to a sharp decline in the stock. Reduced usage from a major AI customer remains the most immediate challenge, even as broader demand for cloud monitoring and AI infrastructure continues to support the business. The next earnings report will help clarify whether the slowdown is temporary and customer-specific or signals a more persistent moderation in growth.
