Microsoft's Stock Soars 17% in Biggest One-Day Gain Since 2008, Adding $483 Billion in Market Value

Microsoft's stock prices skyrocketed on Thursday, surging by a staggering 17% to above $455, marking the company's largest single-day gain in nearly two decades. This extraordinary rally added a whopping $483 billion in market value, sending shockwaves throughout the tech industry and beyond.

Background & Context

Microsoft's stock had been experiencing a slump in recent months, depressed by investor concerns over the company's massive investment in the AI sector. The tech giant's stock had plummeted by nearly 30% from its October 2025 high of $555, prompting fears that the company's strategy for converting estimated $190 billion in AI spending into revenue growth was faltering. However, the company's fourth-quarter results, released on Wednesday, appear to have finally convinced investors that CEO Satya Nadella's strategy is bearing fruit.

The AI sector has been a major focus for Microsoft in recent years, with the company investing heavily in the development of its cloud computing platform, Azure. The company's decision to invest in OpenAI, a leading AI research organization, has also been a key factor in its growth strategy. While the lack of clarity surrounding OpenAI's revenue-sharing deal with Microsoft has raised concerns among analysts and investors, the company's latest results suggest that its strategy is paying off.

Key Details

Microsoft's fourth-quarter results exceeded analyst expectations across nearly every metric, with quarterly revenue hitting a record $90 billion, up $13.6 billion (17.7%) from a year ago. Earnings per share came in at $4.74, above the consensus estimate of $4.24, amid total quarterly net income of $35.8 billion. The company's cloud computing platform, Azure, took center stage during the earnings call, with CEO Satya Nadella unveiling the platform's revenue figures for the first time.

Azure's revenue growth was a key highlight of the earnings call, with the platform's revenue crossing the $100 billion mark for the first time during the 2026 fiscal year. Analysts had estimated Azure's revenue at $29.9 billion for the fourth quarter, up from $20.9 billion a year ago, but the company's actual revenue exceeded this estimate, sailing past the company's guidance of 39% to 40% growth. Hood guided 45% Azure growth for the next quarter, which ends in September, above the 41% analysts had expected.

OpenAI's contribution to Microsoft's revenue was also a notable highlight of the earnings call, with the AI research organization accounting for $24.1 billion in fiscal 2026 revenue. While OpenAI still owes Microsoft $6 billion in accounts receivable, the company's revenue-sharing deal with Microsoft has been a major factor in its growth strategy. The deal has raised concerns among analysts and investors, but Microsoft's latest results suggest that the company's strategy is paying off.

What Experts Say

Analysts have welcomed Microsoft's latest results, with William Blair analyst Jason Ader estimating Azure's revenue at $104 billion for the full 2026 fiscal year, up from $75 billion last year. The company's strong revenue growth and forward guidance have been hailed as a major positive for the company, with many analysts upgrading their price targets for the stock. While concerns remain over the company's dependence on OpenAI, Microsoft's latest results suggest that the company's strategy is paying off.
