Alphabet approaches Nvidia in the race to become the world's most valuable company following strong Q1 earnings in cloud, search, and AI.

      TL;DR: Alphabet's market capitalization exceeded $4.6 trillion following a 10% increase in stock price after Q1 2026 earnings surpassed expectations in all areas, with Google Cloud seeing a 63% growth to surpass $20 billion and search queries hitting record levels. The gap with Nvidia, which saw a 6% drop due to reports of OpenAI not meeting growth targets, has narrowed to about $200 billion, with options traders estimating a 53% chance that Alphabet will surpass Nvidia as the world's most valuable company before mid-May.

      On Thursday, Alphabet's share price jumped nearly 10% after the company announced first-quarter revenues of $109.9 billion, representing a 22% year-over-year increase that exceeded analyst projections by nearly $3 billion. Google Cloud reached quarterly revenue of over $20 billion for the first time, growing at a rate of 63%. The cloud backlog nearly doubled quarter over quarter to more than $460 billion. Earnings per share increased by 81%, and search queries reached an all-time high. The stock closed at $381.94, raising Alphabet’s market capitalization above $4.6 trillion. Nvidia closed that day at $198.61, with a market capitalization of around $4.8 trillion, having fallen more than 6% over the prior two sessions after the Wall Street Journal reported that OpenAI had not met its internal user and revenue targets.

      The disparity between the two companies now stands at roughly $200 billion. Options traders estimate there is about a 53% chance that Alphabet will reach $5 trillion by May 15. If this happens, and Nvidia does not rally before its earnings release on May 20, Alphabet will become the world’s most valuable company. The last time it held this position was for two days in February 2016 when it briefly surpassed Apple.

      The earnings figures that influenced the market were not only significant but also represented a fundamental shift compared to Alphabet’s reported figures from a year earlier. Google Cloud’s growth rate increased from 48% in the previous quarter, becoming the fastest-growing division among the three leading cloud platforms; AWS grew by 17% and Microsoft Azure by 33%. Although Google retains third place in market share, it is expanding at nearly double the rate of Azure and almost quadruple that of AWS. CEO Sundar Pichai informed analysts that the company is currently compute-constrained, indicating that cloud revenue would have been higher if capacity had met demand. Revenue from products based on generative AI models rose nearly 800% year over year. Additionally, YouTube advertising revenue reached $9.9 billion, an 11% increase, and Alphabet now boasts 350 million paid subscriptions across YouTube Premium, YouTube Music, and Google One.

      The capital expenditure guidance reveals the other side of the story. Alphabet raised its 2026 capex estimate to between $180 billion and $190 billion, up from an earlier forecast of $175 billion to $185 billion in February. The combined capex commitment for 2026 across the five major hyperscalers is set to exceed $650 billion, a sum larger than the GDP of many European nations. Alphabet's substantial spending indicates that the returns on AI infrastructure investments are materializing faster than the market had anticipated. The $460 billion backlog is not revenue but rather a pipeline of contracted demand expected to convert into revenue over multiple years, confirming that Alphabet’s cloud operations are not speculative, as customers have made commitments.

      Nvidia’s recent drop was not due to its own fundamentals; the company reported $68.1 billion in revenue for its latest quarter, with data center revenue rising by 75%. Its upcoming earnings report on May 20 is anticipated to show revenue around $78 billion, reflecting a 78% year-over-year increase. Nvidia continues to be the leading supplier of GPUs for major AI training and inference workloads globally. However, the narrative shifted concerning Nvidia's largest customers. OpenAI, valued at $852 billion, has faced scrutiny as its growth metrics slowed, and reports of missing internal revenue and user targets negatively affected Nvidia, hinting that demand for AI chips may not be infinite. AMD fell 6%, Arm declined 8%, and Broadcom decreased by 5%, as the entire semiconductor sector experienced sell-offs over concerns that the largest buyer of AI chips was not expanding at the pace that its valuation implied.

      The distinction between Alphabet and Nvidia raises a deeper question about where value is generated in the AI economy. While Nvidia sells the tools, Alphabet utilizes those tools to build services and sell the resultant products. Google Cloud’s $20 billion revenue was derived from providing AI infrastructure and services to businesses. The record search query volumes on Google are driven by AI Overviews, which employ generative models to answer questions directly on the search page, while YouTube’s advertising revenues are bolstered by AI-driven recommendations and content moderation. Alphabet is not merely purchasing AI chips; it is transforming those chips
