Tesla officially unveiled Cybercab on September 3rd and disclosed that its Robotaxi fleet has accumulated over 1 million miles. Goldman Sachs and Barclays analysts believe that Cybercab offers a clear cost advantage, but the presentation did not address the two core issues of Tesla's Robotaxi business: its current small fleet size and slow expansion rate, thus not significantly raising expectations for the business.

Goldman Sachs estimates that if Cybercab's scaled cost can be controlled between $20,000 and $30,000, it would create a cost advantage of approximately $0.05 to $0.30 per mile compared to competitors' upfront vehicle costs of $50,000 to $100,000. However, the firm notes that in the near to medium term, the key determinant of Robotaxi's economics remains whether autonomous driving software can support cross-regional expansion. Barclays emphasized that prior to the Cybercab launch, Tesla's Robotaxi fleet in Austin was still under 100 vehicles, and the presentation did not provide new growth or financial targets. Both investment banks believe that while lower vehicle costs can improve the economics per vehicle, if the fleet cannot expand rapidly, the cost advantage will be difficult to translate into revenue and profit.
