Waymo has acquired a 5,500-acre proving ground in Wittman, Arizona, for $220 million to expand its autonomous vehicle testing infrastructure. The site, previously owned by a shell company associated with Apple, includes a high-speed oval, a city course, and a freeway track. This purchase supports Waymo’s ongoing efforts to scale its fleet and refine its driverless technology.
The Details of the Arizona Acquisition
Waymo officially acquired the 5,500-acre testing facility on June 5, 2026, according to documents filed with Maricopa County. The property was held by Route 14 Investment Partners LLC, a Delaware-based entity linked to Apple. As reported by TechCrunch, the $220 million transaction provides Waymo with a massive, controlled environment for vehicle development.
The facility is significantly larger than Waymo’s existing test sites, such as the Castle Proving Ground in California and the Transportation Research Center in Ohio. The Arizona site features:
- A 115-acre city course for urban driving simulation.
- A 35-acre vehicle dynamics area.
- A four-mile oval track.
- A dedicated freeway course designed for high-speed autonomous testing.
Why Waymo Needs More Testing Space
A Waymo spokesperson confirmed to TechCrunch that the company will use the new location to conduct rider-only testing, motion control evaluations, and operational training. The expansion arrives as Waymo scales its commercial presence; as of March 2026, the company operates in 10 U.S. metropolitan areas with over 3,700 robotaxis in service, according to Wikipedia.
The acquisition also highlights the shift in the autonomous vehicle landscape. Apple previously used the site to test prototypes for “Project Titan,” an effort the tech giant abandoned in early 2024 after spending billions of dollars. Apple had purchased the land for $125 million in 2021 after years of leasing it.
Comparison of Testing Capabilities
The following table outlines how the new Arizona facility compares to the history of the site and Waymo’s broader operational needs:
| Feature | Apple (Project Titan Era) | Waymo (Current) |
|---|---|---|
| Ownership Status | Sold in 2026 | Purchased for $220M |
| Primary Use | Prototype development | Rider-only and motion control testing |
| Scale | 5,500 acres | 5,500 acres |
What Happens Next for Waymo?
Waymo continues to grow its reach and technical capability. In February 2026, the company raised $16 billion in funding, reaching a valuation of $126 billion. With the addition of the Wittman site, the company is better positioned to conduct the complex, repetitive testing required to support its goal of providing 500,000 paid rides per week. The new facility will allow Waymo to simulate diverse driving scenarios in a controlled, safe environment, ensuring the company maintains its current pace of expansion across the United States.
