Nvidia's AI Dominance Fuels Record Revenue, But Is the Stock Still a Buy?
Nvidia (NASDAQ: NVDA) delivered another blockbuster earnings report last week, underscoring its seemingly unassailable position at the heart of the artificial intelligence revolution. The company's fiscal 2026 fourth-quarter results revealed revenue growth that continues to defy gravity, powered by relentless demand for its graphics processing units (GPUs) and an expanding ecosystem of AI solutions.
For the quarter, revenue surged 73% year-over-year to $68.1 billion, handily beating analyst estimates of $66.2 billion. Adjusted earnings per share jumped 82% to $1.62. The data center segment, the core of Nvidia's AI business, remained the primary engine, with revenue climbing 75% to $62.3 billion. Notably, networking revenue within this segment—driven by NVLink, InfiniBand, and Spectrum-X products—skyrocketed over 250% to $11 billion.
"We are now seeing accelerated adoption across both training and inference deployments," the company stated, highlighting broad-based strength. Cloud computing giants remain its largest customers, with Nvidia forecasting universal adoption of its upcoming Vera Rubin AI platform. The company also reported its sovereign AI business—serving nation-states building domestic capabilities—tripled revenue to $30 billion for the full fiscal year. Sales in China, however, were negligible despite recent approvals for modified H200 chips.
Other segments showed robust health: gaming revenue grew 47% to $3.7 billion, while professional visualization sales jumped 74%. Automotive revenue saw a more modest 2% quarterly increase. Financially, Nvidia generated a staggering $34.9 billion in free cash flow for the quarter, ending the year with a net cash position of over $54 billion.
The outlook remains bullish. Nvidia guided for fiscal Q1 revenue of approximately $78 billion, representing 77% growth, and stated it has secured supply chain capacity to meet demand through 2027. Analysts point to the company's transition from a GPU supplier to a provider of full-stack AI systems—encompassing hardware, its proprietary CUDA software, and networking—as a key moat.
Despite the stellar performance, valuation debates persist. The stock trades at a forward P/E ratio around 25, which many consider reasonable given its growth trajectory. "We are still in the early innings of global AI infrastructure build-out," said one Wall Street analyst. "Nvidia isn't just riding a wave; it's providing the essential tools to create it."
Investor Perspectives
Michael Chen, Portfolio Manager at Horizon Capital: "The numbers are undeniable. Nvidia has executed flawlessly, and its ecosystem lock-in is profound. The networking growth is particularly telling—it shows customers are buying entire systems, not just chips. At 25 times forward earnings, it's arguably still undervalued for a company with this growth profile and competitive advantage."
David Rivera, Retail Investor: "I've been holding since 2020, and every quarter feels like a victory lap. The cash flow is insane. They're not just a tech stock; they're the foundational pick-and-shovel play for the AI gold rush. I'm adding on any dip."
Sarah Fitzpatrick, Chief Analyst at Greenleaf Research: "The dependence on a handful of cloud providers is a glaring risk. What happens when their capex cycles slow? The China situation is also a sword of Damocles. This stock prices in perfection for the next decade. One stumble and the multiple will contract violently."
Rajesh Kapoor, Independent Tech Consultant: "It's a fantastic company, but the law of large numbers is real. Sustaining 70%+ growth on a $300B+ revenue base is a Herculean task. Competition from AMD, in-house silicon at cloud providers, and potential regulatory headwinds are being completely ignored by the market's euphoria. This is peak momentum, not a value buy."
