- Google's own AI Overviews reducing clicks-per-query
- Advertiser experimentation with alternative placement channels
Management disclosed AI Overviews is live across 1B+ queries monthly as of early 2026. Click-through rate impact monitoring is the key evidence gate.

Cloud operating margin trajectory: loss → breakeven → low-single-digit → now approaching mid-single-digit EBIT margin. This materially changes the consolidated earnings model.
