Musk says Optimus and Cybercab will be 'the vast majority' of Tesla's value days before Q3 earnings

Elon Musk said in a late-night post on X this weekend that Tesla's Optimus humanoid robot and its Cybercab robotaxi "will be the vast majority of Tesla's value". The comment frames TSLA as a robotics and AI company rather than a carmaker days before it reports.

Tesla reports third-quarter results after the close on Wednesday, October 21, with a call at 5:30 p.m. ET. Consensus EPS is about $0.45, per SentiSense's earnings calendar. FXEmpire put expected revenue at $28.11 billion, with EPS down 10.0% from a year earlier, while LSEG estimates cited by CNBC show earnings down 14.5% on revenue roughly 1% lower. Third-quarter deliveries were 486,532 vehicles, down 2% from a year earlier but ahead of estimates.

Tesla is part of a heavy week for the AI trade: META also reports after the close on Wednesday and NFLX reports on Tuesday, October 20, while chip stocks have just come off a sharp selloff.

What to watch: any concrete Optimus production or Cybercab deployment figures, whether management quantifies the robotaxi business at all, and how auto margins hold up with deliveries lower year on year. Musk's valuation claim is his own forecast and comes with no revenue figures, so the call is where investors will look for numbers.
