Microsoft is back in the $4 trillion market cap club, and Yahoo Finance's Dan Howley breaks down the Maia 300, the company's latest in-house AI chip, due to roll out in 2027. Microsoft says the chip beats widely available GPU-based systems in certain applications and plans multiple gigawatt-scale deployments, part of a push already seen at Google and Amazon to reduce dependence on Nvidia and AMD. Howley explains why Microsoft will keep buying third-party chips, how its multi-silicon approach mirrors the multi-cloud era, and what owning the stack from silicon to models to agents could mean for its own software.
