Alphabet subsidiary operating 500K+ paid robotaxi rides/week across 10 US cities; raised $16B at $126B valuation in Feb 2026; expanding to 20+ new cities and London
Waymo is Alphabet's autonomous vehicle subsidiary and the world's most operationally advanced robotaxi company, with roots in Google's self-driving car project that began in 2009. Spun out as an independent Alphabet subsidiary, Waymo has spent over 15 years accumulating real-world driving data, refining its sensor suite (combining lidar, radar, and cameras), and developing the Waymo Driver — the AI stack that enables fully driverless operation across diverse urban environments.\n\nWaymo One, its commercial robotaxi service, operates in San Francisco, Phoenix, Los Angeles, Austin, and additional US cities, completing over 500,000 paid rides per week as of early 2026. Unlike competitors that rely on remote safety operators, Waymo vehicles operate fully autonomously on public roads. The company is also developing Waymo Via for autonomous trucking and expanding its geographic footprint through partnerships with ride-hailing platforms and automotive OEMs.\n\nWaymo raised $16B at a $126B valuation in February 2026, reflecting investor confidence in its lead position in a winner-take-most autonomous mobility market. With expansion to 20+ new cities planned, the company is transitioning from proving the technology works to demonstrating unit economics at scale. As the robotaxi market accelerates, Waymo's decade-plus operational head start, unmatched safety record, and Alphabet's resources give it a structural advantage that rivals are struggling to close.
Sidewalk autonomous delivery robot company spun out of Uber Eats; publicly traded with Nvidia backing and a 2,000-robot Uber Eats deployment deal.
Serve Robotics Inc. is an American autonomous sidewalk delivery robot company headquartered in Redwood City, California, and listed on the NASDAQ. Originally spun out of Uber Eats' robotics division in 2021, the company makes Level 4 autonomous delivery robots that navigate urban sidewalks to deliver food, groceries, and packages directly to consumers. Serve Robotics is backed by NVIDIA, which has invested in and supplies the company with Jetson-based AI computing platforms.\n\nServe Robotics has an exclusive commercial agreement with Uber Eats to deploy up to 2,000 autonomous delivery robots across multiple US markets, representing one of the largest autonomous delivery robot deployment commitments globally. The robots operate on sidewalks at pedestrian speed, equipped with cameras, lidar, and AI to avoid obstacles and interact safely with pedestrians. Deliveries are offered at a cost comparable to or lower than traditional courier delivery, with the model targeting positive unit economics at scale.\n\nAs of 2025, Serve Robotics has been scaling operations in Los Angeles and expanding to additional cities, building operational data and refining its autonomy stack. The company's differentiated positioning — Level 4 sidewalk autonomy rather than road-based delivery — insulates it from the heaviest vehicle regulatory burden while opening a large last-mile delivery market. Serve Robotics represents the convergence of robotics, AI, and the gig economy model pioneered by Uber Eats.
