AMD's data center business is now too big to dismiss as a side story

AMD reported third-quarter results after the close that blew past Wall Street's expectations, with its data center division nearly doubling and CEO Lisa Su saying the company can keep up with accelerating demand for AI chips.

When data center alone accounts for nearly two-thirds of its total revenue and the next quarter is guided to 66% growth, this is no longer a company riding the AI wave on the side — it has become the wave.

Apple's margin warning signals that building AI into hardware is expensive in ways investors underestimated

Apple posted record quarterly revenue with iPhone sales surging, but the stock fell after management guided its profit margin sharply lower, citing soaring memory costs and AI-related expenses, with the new CEO also flagging supply problems pushing its latest iPhone model to late January.
