Record Q4 revenue of $90 billion and 43% Azure growth drove Microsoft’s biggest-ever one-day market-cap gain, while investors weighed AI spending, Apple’s after-hours drop and broader tech-market volatility.
Microsoft reported record fourth-quarter results, including $90 billion in revenue and 43% Azure growth, helping ease investor concerns that heavy AI-related capital spending would outweigh near-term returns. The stock jumped 15% in its best day since 2008, adding nearly $450 billion in market value in the largest single-day gain ever recorded by a company. Apple, by contrast, fell in after-hours trading after its results, putting roughly $350 billion of market value at risk. CNBC also reported that hedge fund Situational Awareness suffered steep losses tied to AI infrastructure and software positions, prompting a scramble for cash to meet margin requirements and an agreement by Citadel to buy its publicly traded assets.
