Nvidia Holds $5.5 Trillion Crown as Alphabet Cloud Surge Narrows Gap
With Alphabet’s market capitalisation reaching $4.8 trillion and Apple close behind at $4.4 trillion, the race for global corporate dominance is intensifying, yet analysts remain confident in Nvidia’s sustained lead.
As of May 2026, Nvidia stands as the world’s largest corporation with a market capitalisation of $5.5 trillion, a valuation achieved by only one company in history. Alphabet ranks second at $4.8 trillion, having significantly outperformed Nvidia over the past year. Apple sits in third place with a market capitalisation of $4.4 trillion. While the gap between the top two is narrowing, analysts suggest Nvidia is likely to retain its position as the largest company by the end of 2026 due to sustained demand for artificial intelligence computing power.
Alphabet reported a 22% year-on-year revenue increase to $109.9 billion in the first quarter, a figure driven largely by a 63% surge in cloud sales. The company’s cloud operating income climbed 203% year-on-year to $6.6 billion, while total operating income grew by 30% to $39.7 billion. The cloud backlog almost doubled quarter-on-quarter to $460 billion, prompting plans to increase capital expenditure in 2027 to meet rising demand for cloud-related services.
Nvidia’s CEO, Jensen Huang, has projected $1 trillion in purchase orders for its AI platforms, specifically the Blackwell and Vera Rubin systems, through 2027. The Vera Rubin platform is scheduled to become broadly available in the second half of the year, yet customers appear to be lining up for the technology well in advance. This guidance underscores the scale of demand for the chipmaker’s hardware, which remains the market leader in AI infrastructure.
Despite the intense competition, Nvidia’s valuation metrics suggest room for growth. The company’s forward price-to-earnings ratio is 26.5, a figure not substantially higher than the 24.4 average for information technology stocks. Given the continued rapid adoption of AI services and the growing demand for computing power to run inference models, analysts view Nvidia as capable of matching the performance of its peers to maintain its corporate crown.
The competitive landscape highlights the diverging strategies of the tech giants. Alphabet’s advertising segment remains its largest revenue source, yet its cloud division is the fastest-growing. Meanwhile, Nvidia continues to benefit from Alphabet’s increased capex spending, as the cloud provider’s expansion directly translates into demand for Nvidia’s AI chips. Both companies are recognised for their wide economic moats and strong innovative capabilities, though Nvidia’s current lead appears difficult to overturn within the year.
Interestingly, The Motley Fool’s Stock Advisor team recently identified 10 best stocks to buy, notably excluding Nvidia from the current list despite its market leadership. The investment firm noted that Nvidia was included in their "10 best stocks" list in April 2005, a recommendation that would have yielded significant returns for early investors. This historical context underscores the long-term potential of both companies, even as their immediate market positions shift.
