Tesla shares rose 0.3% in overnight trading before Monday's session as investors focused on reports of unsupervised Cybercabs operating in Austin and Elon Musk's broader autonomy, robotics and energy ambitions. Cathie Wood of ARK Invest endorsed footage amplified by Tesla AI and Autopilot lead Ashok Elluswamy, while Musk confirmed Tesla was preparing to flood Austin with Cybercabs. Tesla plans an invite-only "Exclusive Access: Cybercab" event on Sept. 3, with a public livestream. The two-seat vehicle lacks a steering wheel and pedals and is expected to join Tesla's existing Robotaxi service using the Full Self-Driving software stack deployed in its Model Y fleet. Musk also said Tesla and SpaceX were each building 100 gigawatts a year of solar production capacity, while Terafab AI's Texas semiconductor project secured a tax-value limitation agreement and is scheduled to begin construction in December 2028. The project carries an initial $16.8 billion investment and at least 3,000 jobs, with a May filing outlining a possible $55 billion first stage and up to $119 billion across later phases. ARK Invest estimated eventual capital needs could reach $1 trillion. Musk additionally clarified that SpaceX, rather than he personally, acquired mobile-power provider APR Energy for $1 billion. Skeptics, including Future Fund managing partner Gary Black, questioned robotaxi economics and Tesla's ability to fund rising capital expenditures. Visible Alpha projections show cash outflows from 2026 through 2028 before free cash flow returns in 2029 as robotaxi and Optimus revenue begins to materialize. S&P Global Market Intelligence estimates Tesla will end 2026 with $23 billion in net cash. TSLA is up 12% this month but down 4% last week and 22% year to date, while SpaceX shares under the ticker SPCX have gained 22% over the past month but lost 12% this year.
