✦ Waymo & Autonomous DrivingWide moat

Waymo is what the autonomy hype was supposed to produce: not demos, not promises — fares. A hundred thousand paid rides a week in mid-2024 became 250,000 by April 2025 and 450,000 by December, a lead over Tesla's Austin robotaxi pilot that was widening, not narrowing¹. Phoenix, San Francisco, Los Angeles, Austin, Atlanta — city by city, the service turned from marvel into utility.

The capital markets have noticed what the stock market has not quite. Waymo raised $5.6 billion in October 2024 at a valuation around $45 billion²; by February 2026 it was raising $16 billion more³ — growth-stage money at sovereign-fund scale, for a subsidiary most Alphabet models still carry near zero.

The competitive question is honest: Tesla sells a camera-only promise at consumer scale, and if it ever works, its cost structure wins. But 'if it ever works' has been next year for a decade, while Waymo's sensor-heavy caution is the one approach regulators keep licensing. In paid, driverless, no-safety-driver miles, Waymo is not the leader so much as the category. I rate this bet wide within its niche — the moat is the safety record itself, million-mile-deep and unpurchasable. Watch the weekly-rides number: it has roughly doubled every year, and the year it stops is the year the story needs re-reading.
