Tesla shares experienced volatility on January 21, 2026, dropping about 4% initially before rebounding nearly 3%, following CEO Elon Musk's comments on the slow start to production for the Cybercab robotaxi and Optimus humanoid robot. Musk described the early ramp-up as 'agonizingly slow' due to the novelty of the technologies. Investors await the company's Q4 earnings report on January 28 for more details on timelines and regulatory hurdles.
On January 20, 2026, Elon Musk posted on X, cautioning that initial production for Tesla's Cybercab and Optimus would be 'agonizingly slow.' He explained, 'With the important caveat that initial production is always very slow and follows an S-curve. The speed of the production ramp is inversely proportionate to how many new parts and steps there are. For Cybercab and Optimus, almost everything is new, so the early production…'
The Cybercab is a fully autonomous two-seater vehicle without a steering wheel or pedals, targeted for volume production in 2026. Tesla plans to test robotaxi services in Austin using its Full Self-Driving software. Optimus, the humanoid robot, is slated for limited production toward the end of 2025.
Tesla's stock (TSLA) reacted sharply on January 21. Shares fell 4.2% to $419.25 in early trading amid concerns over delays and regulatory challenges, including federal exemptions for driverless operations and a U.S. auto safety probe with a response deadline of February 23. The drop mirrored broader market unease from President Donald Trump's tariff threats. However, the stock later rebounded, climbing about 1% to $423.32 and fluctuating between $417.53 and $424.21, with a nearly 3% gain by session's end, driven by optimism around robotaxi timing, energy storage deliveries, and AI chip developments.
Tesla reported delivering over 418,000 vehicles and 14.2 gigawatt-hours of energy storage in Q4. The company also cut about 1,700 jobs at its Berlin gigafactory, bringing employment there to 10,703. Investors are focusing on the January 28 earnings release and Q&A webcast at 5:30 p.m. Eastern for insights into automotive margins, spending, autonomy timelines, and capacity figures.
Regulatory approvals remain a key variable, with experts noting that even technologically ready projects face delays. A market strategist said, 'The early-stage outputs are expected to be extremely limited… It’s a clear signal that investors should expect a gradual ramp-up rather than immediate volume.' Morgan Stanley projects 1.6 million vehicle deliveries in 2026 but warns of a potential $1.5 billion free cash flow burn due to higher capital expenditures.
Tesla's push into autonomy and robotics positions it against competitors like Alphabet's Waymo, emphasizing revenue from software subscriptions and fleets over traditional vehicle sales.
