This analysis is part of Google’s AI Full-Stack Domination, a deep dive by The Business Engineer.

Google (Alphabet) exceeded $400 billion in revenue for the first time in its history. AI is the inflection point that made this happen.
What Google has quietly built over a decade is the only business model in tech that cuts through every layer of the AI stack simultaneously: from custom silicon at the bottom to consumer subscriptions at the top, with model infrastructure, advertising, content, and developer platforms filling every layer in between.
The Eight-Layer Stack
1. Silicon & Compute: TPU v7 Ironwood, Anthropic committed to 1M TPUs, 9/10 top AI labs on Google Cloud. 2. Foundation Models: Gemini 3 Family, 10B+ tokens/min, 400% Gen AI revenue growth. 3. Cloud & AI Platform: $70B+ ARR, margins 17.5% → 30.1%, $240B backlog. 4. Developer Ecosystem: 10B+ tokens/min API, 350 customers at 100B+ tokens/month. 5. Consumer AI Apps: Gemini App 750M MAUs, 500M Indian consumers trial. 6. Enterprise AI & Agents: 8M+ paid seats, 2,800+ companies in 4 months. 7. Ads & Agentic Commerce: Search $63.1B Q4 (+17%), UCP with 20+ partners. 8. Physical AI & Autonomous: Waymo $126B valuation, 20M+ trips.
The Bottom Line
Google is the only company with production-scale presence across all 8 layers. Every competitor excels at 1-2 layers but depends on external partners for the rest. The convergence is the moat—and the window for competitors to match it is closing fast.
