AI Civil War: Amazon Wins as Microsoft's Empire Cracks

MarketBeat argues a potential rift between Microsoft and OpenAI — with OpenAI reportedly exploring Amazon Web Services — is reshaping the AI cloud landscape and investor positioning. The news undermines Microsoft’s exclusive-AI narrative, coinciding with about a 20% year-to-date drop in MSFT shares and prompting a $60 billion buyback. Conversely, Amazon is portrayed as the beneficiary: AWS’s open-ecosystem strength and enterprise credentials support a steady 7% YTD gain in AMZN and robust revenue growth. The piece frames this as a clear performance divergence that should influence allocations to cloud/AI exposure ahead of upcoming earnings, favoring Amazon as the cleaner AI-infrastructure play.
