Microsoft (NASDAQ:MSFT), the cloud and software giant, unveiled Maia 300 as it pushes to run more AI services on its own silicon. Shares traded at $540.54 at 10.50am EST on October 12, up about 1.07%. The ambition is big: according to Reuters, Microsoft could deploy more than one million chips next year. Investors now need to see whether that scale translates into better margins.

Power efficiency is the selling point. Microsoft expects Maia 300 to deliver 40% more tokens per megawatt than leading GPU systems, with production deployment and expansion to multi-gigawatt scale beginning in 2027. But the comparison leaves questions open. The company has not named the competing systems or detailed the workloads behind that headline figure. More output from the same power budget could matter enormously. The benchmark still needs context.
Building chips is only half the battle. Manufacturing yields, software efficiency and depreciation will determine how much money Microsoft actually saves. The valuation picture puts shares 8.72% below the $592.20 GF Value estimate, suggesting a modest discount rather than a huge cushion. That estimate is no guarantee of upside. The real test is simple: can Microsoft serve more useful AI responses at a lower cost without sacrificing performance?
