Nvidia's Growth Engine Hits a Supply-Side Speed Bump

Nvidia's Q2 revenue surged 106% to $96.2B, but Q3 margin guidance of 74% and supply constraints triggered a 4.1% stock drop.

The arithmetic of Nvidia's latest earnings report is striking: revenue up 106 percent to $96.2 billion, data center sales climbing 117 percent to $89 billion, and adjusted earnings per share jumping 111 percent to $2.22 — all comfortably ahead of Wall Street's consensus estimates. Yet the market's response on Friday was anything but celebratory. The stock shed 4.1 percent to close at €187.78, a pullback that leaves the shares 7.3 percent below their 52-week high of €202.50, even as they maintain a 3.6 percent premium to the 50-day moving average of €181.21.

The Margin Story Behind the Headlines

Investors didn't need to dig deep to find the source of their unease. Management's guidance for the third quarter calls for gross margin of 74 percent, stepping down to 71.5 percent in the fourth quarter — a visible erosion from the current 75.0 percent level. The culprit: rising costs for high-bandwidth memory components, the same supply constraint that CFO Colette Kress flagged as a limiting factor on growth. Adding to the downbeat tone, restrictive comments from Federal Reserve Governor Christopher Waller weighed on sentiment, turning what should have been a straightforward beat-and-raise moment into a session of profit-taking.

The margin trajectory matters because it complicates the otherwise bullish narrative. Nvidia's guidance of $108 billion in third-quarter revenue, plus or minus 2 percent, came with an important caveat: it assumes zero data center revenue from China. The company also offered a preliminary expectation of roughly 70 percent revenue growth for fiscal 2028 — ambitious, but explicitly conditional on resolving the very supply constraints now squeezing margins.

A Customer Base Voting With Its Wallet

Demand signals, at least, remain unambiguous. Amazon Web Services has tripled its Nvidia GPU order to 2 million units, marking the first deployment of Nvidia's new Vera CPU across its infrastructure. The deal, which Reuters and CNBC both identified as a key driver of the post-earnings stock reaction, provides rare visibility into future deliveries. When the shares initially dipped after the report before reversing higher during the earnings call, it underscored just how closely investors are parsing every supply-side detail.

The broader ecosystem is mobilizing as well. AI cloud provider Lambda secured roughly $1 billion in short-term private debt — with Nvidia's backing — to purchase chips for a Microsoft collaboration. SpaceXAI has committed to Nvidia's Vera CPU for large-scale agentic AI workloads. And Nvidia itself has earmarked $18 billion in equity investments for the remainder of the fiscal year, with its private company stakes already reaching $47.9 billion by end of July. The $500 billion in financing commitments from six major US financial institutions, organized with Nvidia's involvement, suggests capital for AI infrastructure buildout will not be the bottleneck.

The Rising Cost of Commitment

But Nvidia's deepening entanglements carry their own risks. Long-term supply obligations have more than doubled in a single quarter to $279 billion — a figure that cuts both ways. In today's tight market, it secures component access; if memory prices soften, it becomes a liability for inventory valuation. Reuters also reported that Nvidia has committed to guaranteeing up to $105 billion for a 20-year data center lease for OpenAI in Ohio, a pledge that ties up capital and increases dependence on individual customers' financial health.

Insider activity adds another layer of scrutiny. Regulatory filings show $410.44 million in insider sales over the past three months. Ajay K. Puri, Executive Vice President of Worldwide Field Operations, departed on August 24 and is no longer subject to Section 16 reporting requirements. Neither development is necessarily bearish on its own, but in a stock trading at these levels, they invite questions.

What to Watch Next

The near-term calendar offers concrete markers. Nvidia pays its next quarterly dividend of $0.25 per share on October 1, with a September 10 record date. Third-quarter results are expected November 18. Between now and then, the market will be watching whether the memory supply situation improves, whether hyperscaler orders convert into actual deliveries, and whether the margin guidance for the fourth quarter proves conservative or accurate.

The bull case rests on a simple proposition: with demand seemingly secured through deals like AWS's expanded order, the constraint is purely operational. If Nvidia can resolve its memory supply issues, the $108 billion guidance could prove a floor rather than a ceiling, and the stock's path toward its 52-week high becomes a question of when, not if. The bear case is equally straightforward — the $279 billion in supply commitments and the OpenAI guarantee create a chain of obligations that could strain the balance sheet if any link weakens. With 30-day volatility running at 45 percent, the market is clearly pricing in the possibility of sharp moves in either direction.
