Revenue at Facebook owner Meta Platforms surged 24% in the December quarter, benefiting from online ad targeting bolstered by artificial intelligence. "Meta's headline numbers are a really interesting reflection ‌of the market’s attitude toward spending in AI space," said John Belton, portfolio manager at Gabelli Funds. "All else equal, the market would typically be concerned, but they have a big revenue guide for the first quarter." Microsoft reported growth in its Azure cloud-computing business that was only slightly above expectations, also far lagging record quarterly spending. It predicted Azure growth to stay stable in the period from January to March, after slowing in the last ​three months of 2025, which it partially blamed on AI chip capacity constraints.
