Tesla Stock Forecast: Cybercab Scaling Doubted, Fleet Size Key to Robotaxi Valuation, $351 May Be Bull-Bear Line
On September 4 Eastern Time, Tesla shares fell over 6% as investors shifted focus from Cybercab's launch to its commercial scalability. Despite cost advantages and registered Texas vehicles, analysts noted a lack of clear deployment timelines, production targets, and financial guidance, prompting caution. Technically, the stock broke below key moving averages, entering consolidation. The 160-day moving average and the $349.13 Fibonacci level serve as critical near-term support. A failure to hold these levels could trigger a deeper correction toward $329.35, while a sustained recovery requires reclaiming moving averages above $356.72 to resume upward momentum.

TradingKey - On September 4 Eastern Time, Tesla (TSLA) shares fell more than 6%, giving back all of yesterday's gains. Market reaction shows that investor focus on Cybercab's official entry into the Robotaxi fleet has shifted from "whether it can be launched" to "whether it can achieve commercial operation at scale."
According to public registration records, as of the previous week, Tesla had registered approximately 420 autonomous vehicles in Texas, including 45 Cybercabs, with the remainder mainly being Robotaxi-version Model Ys. This data does not indicate that all vehicles have entered commercial operation; Goldman Sachs cautioned that some vehicles may still be in the testing phase or equipped with safety monitors.
Fleet Size Becomes Key to Tesla Robotaxi Valuation
Morgan Stanley outlined two scenarios ahead of the event: In a bull case, if Tesla can launch an unsupervised paid Cybercab service in Austin, Houston, and Dallas, and expand its Texas fleet to 25 to 50 vehicles within days or weeks, the market could view it as a signal of accelerating autonomous driving commercialization.
However, if the event is limited to product displays, rides in restricted areas, or a small vehicle deployment, it will remain difficult for the Robotaxi business to generate meaningful revenue validation in the short term, and Tesla's stock price could come under pressure. This stock pullback reflects the market's view that the event failed to provide a sufficiently clear deployment scale, production targets, and expansion timeline.
Barclays analyst Dan Levy stated that the event was broadly in line with expectations, but the company disclosed no new growth or financial targets, which may limit its short-term catalytic effect. Wells Fargo and Evercore ISI also noted that sparse event details and limited management communication prompted investors with high expectations to turn cautious.
Can Low-Cost Cybercab Change the Robotaxi Competitive Landscape?
Tesla's core advantage lies in its dedicated vehicle cost and technical approach. Barclays notes that as a low-cost, purpose-built driverless vehicle, if Cybercab's software capabilities mature, it can use a solution independent of high-definition maps to replicate faster into new operating regions.
Goldman Sachs pointed out that if Cybercab's per-vehicle cost can be kept between $20,000 and $30,000, significantly lower than the upfront vehicle investment of $50,000 to $100,000 for some competitors, Tesla may hold an operating cost advantage of $0.05 to $0.30 per mile.
However, vehicle manufacturing cost is not the sole determinant of the Robotaxi economic model. Goldman Sachs emphasized that in the near-to-medium term, what truly impacts unit economics is whether the software can support operations across broader regions and whether the system can be replicated at a lower marginal cost. In other words, Cybercab's commercial value still depends on whether autonomous driving software, regulatory approvals, remote operations, and fleet utilization can be delivered in sync.
Tesla Technical Analysis
Tesla's stock price rebounded from near $297.38, briefly testing above $380 before retreating rapidly. Currently, the price sits above the 0.382 Fibonacci retracement level ($349.13) and below the 0.5 Fibonacci retracement level ($365.12).

From the 2-hour structure perspective, the stock price failed to challenge the 0.618 Fibonacci retracement level ($381.10) yesterday, and pulled back rapidly today, re-entering a short-term consolidation phase.
The latest pullback sent the price below the 5-day moving average ($359.04), 20-day moving average ($360.67), 10-day moving average ($361.61), and 80-day moving average ($356.72), turning short-term moving averages from support into resistance. Currently, the 160-day moving average ($351.69) remains nearby below the price, serving as the final near-term dynamic support that bulls must defend.
If the stock price falls below the 160-day moving average ($351.69) and further loses the 0.382 Fibonacci retracement level ($349.13), the previous rebound initiated from near $297.38 will weaken significantly, potentially retreating toward the 0.236 Fibonacci retracement level ($329.35) later on.
If it can subsequently reclaim the 80-day moving average ($356.72) and further move back above the 5-day moving average ($359.04), 20-day moving average ($360.67), and 10-day moving average ($361.61), the stock will have a chance to retest the 0.5 Fibonacci retracement level ($365.12) in the short term. Only an effective breakout and consolidation above $365.12 will allow the rebound structure to develop again toward the 0.618 Fibonacci retracement level ($381.10).
