Tesla Just Spent $4.73 Billion on Capex. Here's Where Every Dollar Went.

Tesla's Q3 capital expenditures reached $4.73 billion, more than double year-over-year, with the company revising its full-year capex forecast to $20 billion. Major investments are directed toward AI infrastructure for autonomous vehicles, Cybercab robotaxi manufacturing, Optimus humanoid robots, energy storage expansion, and semiconductor manufacturing. While these ventures present significant revenue potential—including an estimated $42.4 billion robotaxi market by 2030—success depends on regulatory approvals and market adoption.
