Tesla‘s robotaxi service is doubling its active fleet size roughly every month, according to the company’s latest operational update, as the autonomous ride-hailing network expands beyond its initial launch markets to additional cities across the United States.

The service launched in limited form in Austin, Texas earlier this year, with fully driverless Model Y vehicles picking up passengers through Tesla’s app. The company reported strong early demand, with wait times dropping as the fleet grew and the software handled increasingly complex driving scenarios without intervention.

Tesla says the fleet expansion is constrained primarily by regulatory approvals and not by vehicle supply or software capability. Each new city requires a period of supervised operation before full driverless deployment is permitted, and the company is working through that process with transport authorities in several states simultaneously.

The pace of fleet growth is notable in the context of the broader autonomous vehicle industry. Waymo, which operates the largest commercial robotaxi fleet in the United States, expanded more gradually over several years of supervised testing. Tesla’s approach — training its system using data from millions of consumer vehicles before deploying it commercially — has produced a faster ramp, though critics have noted that the statistical difficulty of edge cases means the comparison is not straightforward.

Tesla’s Full Self-Driving system, which powers the robotaxi service, is now on version 13, a significant update released earlier this year that the company says dramatically improved handling of complex intersections, pedestrian behaviour, and adverse weather conditions. Internal metrics shared with investors show a substantial decline in intervention rates compared to earlier versions.

Elon Musk has repeatedly cited the robotaxi network as Tesla’s most significant near-term revenue opportunity, arguing that converting the existing fleet of consumer Teslas into income-generating autonomous vehicles could unlock value many times greater than the car sales business alone.

Pricing for the robotaxi service is competitive with traditional ride-hailing, and Tesla has said it expects margins to improve substantially as fleet density increases and per-mile costs fall.

The company has not disclosed a specific timeline for reaching profitability on the autonomous side of the business, but analysts tracking the fleet growth numbers say the trajectory suggests a meaningful revenue contribution within the next 12 months.
