Alphabet and Microsoft are standing out as AI winners because they're converting AI spending into real revenue and profits, rather than just chasing hype.

What happened

Alphabet's Google Search revenue grew 19% year-over-year to $60.4 billion（約9.7兆円） in Q1 fiscal 2026, while Google Cloud revenue jumped 63% year-over-year to $20 billion（約3.2兆円） with a backlog that nearly doubled sequentially to $462 billion（約74兆円）. Microsoft's AI business exited Q3 fiscal 2026 with an annual revenue run rate of $37 billion（約5.9兆円）, up 123% year-over-year, and Microsoft 365 Copilot paid seats crossed 20 million with seat additions up 250% year-over-year.

What to watch

Alphabet's Google Cloud backlog of $462 billion（約74兆円） is expected to be recognized as revenue over the next two years, and 75% of Cloud customers are already using Google's AI products. Microsoft's remaining performance obligation rose 99% year-over-year to $627 billion（約100兆円）, indicating strong revenue visibility. Both companies combine near-term monetization with long-term opportunities—Alphabet in autonomous driving (which surpassed 500,000 fully autonomous rides per week at the end of Q1) and Microsoft in enterprise software embedding.
