How this fits the existing thesis
Parent thesis: Megacap tech names are diverging sharply on AI monetization credibility: Meta was upgraded by Wall Street analysts while Microsoft is described as grossly undervalued relative to the tech sector, both benefiting from AI-driven revenue acceleration. Alphabet faces a $208 billion market cap loss in a single session as Apple reportedly reduces its reliance on Google search, threatening a core revenue stream. Amazon continues to leverage its AWS and logistics scale. The theme is not uniform bullishness but a high-stakes AI monetization race where winners and losers are beginning to separate.
