CoreWeave's Beat-and-Raise Quarter Lifts Software Stocks: Datadog and Cloudflare Rise 5%

Datadog stock jumped 5% to $187.79 in afternoon trading on November 11, leading a broad software rally sparked by CoreWeave's beat-and-raise quarter. The bounce starts from a deep hole: Datadog is still down 36% over the past month. But the direction changed, and it changed because of a report from a company Datadog doesn't compete with directly.

CoreWeave (NASDAQ: CRWV) reported its results after the close on November 10. The quarter beat expectations and the company raised its guidance. That single report eased two fears that had been weighing on the whole sector: that AI infrastructure spending might slow, and that the expansion might not get financed. Tech stocks rallied broadly on the news.

The gains spread across the software names tied to AI workloads. Fortinet (NASDAQ: FTNT) traded at $129.94, up 5%, though it remains down 33% over the past month. Cloudflare (NYSE: NET) reached $320.88, also up 5%. CrowdStrike Holdings (NASDAQ: CRWD) posted the smallest gain of the four, rising 4% to $235.17.

Why does one company's report move the whole group?

The answer lies in how intertwined these businesses have become. Datadog monitors cloud and AI applications. Cloudflare runs a global network that handles growing AI traffic. CrowdStrike and Fortinet secure the expanding infrastructure. Each company sits somewhere along the chain that connects AI compute to end users, and each depends on the same underlying force: continued, funded AI expansion.

That's why CoreWeave's quarter mattered beyond CoreWeave. When the market worried that AI infrastructure spending couldn't be financed, it repriced every company exposed to that spending. When those fears eased on November 10, the same companies rebounded together.

The rally also coincided with a hawkish signal from the Federal Reserve. Chicago Fed President Austan Goolsbee called the latest inflation report "borderline disturbing" while the central bank weighs more rate hikes. Higher rates typically weigh on growth-oriented software stocks, which makes the day's gains more notable — and more fragile.

What knocked Datadog down in the first place?

Datadog's slide traces back to its own Q3 2026 report, filed with the SEC and released on November 4. The headline numbers looked strong. Revenue rose 35% year over year to $1.2 billion. But management disclosed a wrinkle: several large customers, including AI customers, renewed their contracts early at lower pricing in exchange for bigger commitments.

The company's Q4 2026 guidance added to the caution. Datadog said it assumes revenue from its largest customer only at that customer's minimum commitment — even though the account actually spent above that level in Q3. That conservative read set the tone for a month of selling.

The early renewals reflect a longstanding strategy, not a new problem. CFO David Obstler described the approach on the earnings call: "Our motion is to increase the commitment of customers, broaden the platform, and extend the contract."

CEO Olivier Pomel offered a scale marker on the same call. Datadog now serves over 850 AI customers, he said — a number that shows how deeply the company has ridden the AI boom.

What do the peers' numbers say?

Momentum looks newer at Cloudflare than at Datadog. Cloudflare's Q3 revenue rose 39% to $782.5 million — its fastest growth in nearly four years. The company raised its full-year outlook on November 5 and guided Q4 revenue to $845 million to $846 million. CEO Matthew Prince didn't hold back: "Our engine is firing on all cylinders, and we've found an even higher gear for this next phase of growth."

Cloudflare's margins tell a more mixed story. GAAP gross margin slipped to 71.2% from 74% a year earlier, as network costs rose with AI traffic. Faster growth is arriving with a real cost attached.

Fortinet's situation is the inverse of Datadog's. The company raised its 2026 outlook after a strong Q3 report on October 28, which makes its month-long, 33% decline stand out against its own results. Fortinet's rebound on November 11 partially closes that gap between fundamentals and price.

Across the group, the pattern is consistent: Datadog leads the day's gains despite carrying the biggest recent losses, while CrowdStrike trails slightly at 4%.

How do these four businesses actually differ?

The four companies monetize AI infrastructure in different ways, and those differences shape how each absorbs an AI spending shift.

• Datadog sells subscriptions priced on committed amounts and usage. Revenue rises and falls with how heavily customers run their cloud and AI workloads. That design helped Datadog ride the AI boom — and it exposes the company when a large AI account cuts consumption.
• Cloudflare leans on a global network and a developer platform. Its Pool of Funds contracts let customers spread spending across security, networking and developer products.
• CrowdStrike sells modules of its Falcon platform by subscription, and Falcon Flex licensing lets customers add more modules over time.
• Fortinet is the most hardware-heavy of the group, pairing FortiGate firewall appliances built on its own FortiASIC chips with FortiGuard security subscriptions and FortiCare support.

The usage-based piece explains Datadog's volatility better than any macro narrative. When one large AI customer changes its spending pattern, the effect shows up directly in revenue.

Can Datadog's rebound outlast the reset?

The open question is whether AI customers that renewed early will expand usage again in coming quarters. The optimists have a concrete anchor. Pomel has said that AI workloads moving to production "drive more cloud consumption and more usage of the data platform," and platform adoption keeps broadening across Datadog's customer base.

The bears have their own case, and it's grounded in the company's own numbers. Datadog's Q4 guidance leans on a cautious read of its largest customer, and higher rates could weigh on growth-oriented software stocks if the Fed follows through. A sharp one-day bounce doesn't settle whether the month-long selloff has run its course.

The tracker to watch is spending from Datadog's largest customer in coming quarters. If that account climbs back above its minimum commitment, the reset reads as a timing quirk. If it doesn't, the usage-based model that powered the AI boom becomes the mechanism that transmits its slowdown — and one CoreWeave quarter won't be enough to lift the group twice.
