Waymo Debuts Custom Chip as California Approves Expansion

A New Brain for Waymo's Robotaxis

Alphabet's self-driving unit Waymo has unveiled a custom-built chip designed to power the next generation of its autonomous vehicles, a move the company says will boost performance while reducing its reliance on outside chipmakers 15. Described as the "brain" behind Waymo's driving system, the silicon is meant to handle the immense computational load required to process sensor data, make split-second driving decisions, and run increasingly sophisticated machine-learning models in real time 5. By developing its own chip rather than depending solely on third-party suppliers, Waymo is following a path already taken by other tech giants seeking tighter control over the hardware that underpins their most strategically important software 1.

Scaling Up the Fleet

The chip announcement lands alongside a broader push to make Waymo's vehicles cheaper and more widely available. The company's next-generation robotaxi, internally referred to as the Waymo Ojai, is being positioned as central to its effort to reach mass scale and, eventually, profitability, and has now opened to all riders in three cities 3. Coverage of early rides in the Ojai suggests the vehicle represents a meaningful step toward lowering the cost per ride, a critical factor if robotaxis are to compete with traditional rideshare economics 23. One analysis also points to the rise of Chinese-made robotaxis entering the U.S. market, framing Waymo's cost and technology improvements as part of a broader competitive race in autonomous vehicle economics 2.

Regulatory Green Light in California

On the regulatory front, Waymo has secured approval from California's Public Utilities Commission to expand its ride-hailing service across 18 counties, a decision that clears the way for gradual rollouts into dozens of new cities 4. The approval extends Waymo's footprint across both Northern and Southern California, with Sacramento and San Diego named as new markets alongside continued growth in the Bay Area and Los Angeles 89. While the approval marks a major regulatory milestone, reports note that the exact timing of service launches in these new areas remains unclear, with rollouts expected to happen gradually rather than all at once 9.

Denver on the Horizon

Beyond California, Waymo is preparing to launch public rides in Denver, where the company has been testing vehicles on city streets since the previous year 6. Executives have indicated a public launch could come "at some point later this year," though no firm date has been set 7. Local reporting describes the testing phase as advanced enough that public pickups are expected "soon," signaling Denver could become one of the next major markets outside California 67.

Why It Matters

Taken together, the custom chip, cost reductions from the new vehicle platform, and simultaneous regulatory wins in California suggest Waymo is trying to solve the twin challenges facing autonomous vehicles: technical scalability and government approval. As competition intensifies, including from lower-cost entrants abroad, Waymo's ability to cut costs while expanding its regulatory footprint will likely determine how quickly robotaxis move from a novelty in select cities to a mainstream transportation option.
