Nvidia has solidified its position as the primary engine of the global artificial intelligence boom, reporting record-breaking financial results for the fourth quarter of fiscal 2026. The company reached a quarterly revenue peak of $68.1 billion, representing a 73% increase from the previous year. This performance was largely propelled by the Data Center division, which saw revenue surge 75% to $62.3 billion, effectively quieting concerns regarding a potential slowdown in infrastructure spending. The chipmaker’s profitability remains exceptional, with gross margins holding steady at 75.2%. For the full fiscal year 2026, Nvidia generated $215.9 billion in total revenue, a 65% jump from 2025. Following these results, the stock price rose approximately 2% in extended trading, bringing the company’s market capitalization to a staggering $4.66 trillion. Investor focus has shifted toward the upcoming first quarter of fiscal 2027, where Nvidia has issued bullish guidance. The company expects revenue to reach $78.0 billion, significantly exceeding market expectations of $72.8 billion. This optimistic outlook is supported by a massive $700 billion projected capital expenditure from major hyperscalers—including Google, Amazon, and Meta—who continue to prioritize AI infrastructure. Product cycles are a major catalyst for 2026. Demand for the current Blackwell architecture remains "exceptional," while the newly announced Vera Rubin platform is expected to enter production in the second half of the year. This next-generation series is designed for "AI factories" and agentic workflows, promising a fivefold increase in inference performance. Despite the financial triumphs, the regulatory landscape in China remains a significant headwind. While a recent agreement eased some export restrictions, U.S. officials confirmed this week that zero H200 chips have been sold to Chinese end-users thus far as licensing details are finalized. Nvidia has prudently excluded all China-related Data Center revenue from its next-quarter guidance. Competition is also intensifying as the market enters the "Inference Era." While Nvidia maintains an estimated 80% to 90% share of the accelerator market, AMD has secured high-profile deals with OpenAI for its MI-series chips. Simultaneously, hyperscalers like Google are increasingly deploying internal Tensor Processing Units (TPUs) to optimize costs, challenging Nvidia’s dominance in specific AI workloads. Nvidia’s current market position reflects a transition from providing standalone chips to delivering full-stack AI supercomputing ecosystems. With a remaining share repurchase authorization of $58.5 billion, the company is signaling confidence in its ability to navigate geopolitical friction and rising competition while maintaining its lead in the global AI race.
