Alphabet, Samsung report weak earnings as investors question AI spending

Business Oct 29, 2026

Big tech had a rough Thursday: Alphabet and Samsung both reported weaker-than-expected earnings, even after pouring money into AI projects.

Investors weren't impressed: Alphabet's shares dropped 10% in after-hours trading, while Samsung's fell more than 5%, pulling down the Kospi Index by 2.9%.

The news has people questioning if all this spending on AI is really paying off.

Microsoft up 2.9%, Oracle up 11%

Not everyone was struggling, though. Microsoft saw its shares climb 2.9% thanks to strong cloud business, and Oracle jumped 11% on upbeat cash flow news.

Still, with global tensions and big economic decisions looming, the tech market feels pretty shaky right now.
