Microsoft's market capitalization jumped by $450 billion in a single day, increasing its total value by more than Apple's market cap, after reporting strong earnings that surpassed analyst expectations. This surge propelled the company's valuation past $4 trillion, making it the second publicly traded company after Nvidia to reach this milestone. Investors reacted positively to Microsoft's substantial investments in artificial intelligence, which are beginning to show significant returns.
The company announced booming sales in its Azure cloud computing business and reported that its Copilot AI tools now have more than 100 million monthly active users. This performance underscored the effectiveness of its AI strategy and its leading position in enterprise AI, despite heavy capital expenditures. Microsoft forecast a record $30 billion in capital spending for the first quarter of the current fiscal year to meet the soaring demand for AI infrastructure.
Analysts praised Microsoft's transformation into a profitable and cash-generative cloud infrastructure and enterprise AI leader. KeyBanc upgraded Microsoft to "overweight" from "sector weight," citing surging Azure growth as resolving previous concerns. Scotiabank also raised its price target for MSFT to $650 from $500. Microsoft's shares rose by as much as 8%, closing up 4.5% on the day.
This stock performance aligns with a broader trend where heavyweight AI players like Nvidia, Microsoft, Amazon, Alphabet, and Meta Platforms now collectively account for a quarter of the S&P 500. Microsoft's multi-billion dollar bet on OpenAI, which powers its Office Suite and Azure offerings, has been a significant catalyst, more than doubling its stock value since ChatGPT's debut in late 2022. Nvidia, another AI bellwether, had reached the $4 trillion milestone on July 9 and subsequently climbed to a record $4.4 trillion market capitalization.
