Microsoft Faces Regulatory Scrutiny Amid Historic Growth

Microsoft's summer of 2026 is shaping up to be less about celebration and more about navigation. The company just posted one of the most explosive single-day gains in stock market history, but it finds itself juggling a historic share-price surge, a looming class-action deadline, an active antitrust complaint, and a regulatory probe across the Atlantic.

The raw figures from Microsoft's fiscal fourth quarter were nothing short of spectacular: revenue hit $90.0 billion, up 18 percent year over year, while Azure and other cloud services grew at a blistering 43 percent clip. Net income climbed to $35.8 billion, and Microsoft 365 Copilot now counts 30 million paying users.

Despite the historic pop, the shares closed Friday at €432.35, still nearly 10 percent below their all-time high of €478.10 from October. Look back twelve months and the stock is actually down 3.10 percent.
