Microsoft Corp. (NASDAQ: MSFT) ended Thursday’s session higher and is seeing only modest movement in extended trading—an important signal that, as of late Thursday, investors are mostly reacting to macro and AI-theme developments rather than a single company-specific shock headline.

As of around 4:29 p.m. ET, MSFT was $482.90 in after-hours trading, down about 0.2% from its regular-session close of $483.98.

Below is what mattered for Microsoft stock after the bell on Dec. 18, 2025, and what to keep on your radar before the market opens Friday, Dec. 19, 2025—including a heavy slate of inflation and consumer data that can move bond yields (and, by extension, mega-cap tech valuations).
