Tesla says Cybercab production has begun, as its capital spending more than doubles
Tesla says it began building the Cybercab in Texas and spent $5.8 billion on capital projects in the quarter, up 142%, leaving free cash flow negative.
On 22 July 2026 Tesla reported second-quarter revenue of $28.2 billion, up 26%, and said Cybercab, its self-driving vehicle, began production at Gigafactory Texas. Capital spending was $5.789 billion, up 142%, and free cash flow was negative $1.092 billion. Tesla is also installing first-generation Optimus robot lines at Fremont, with first builds used for training data (Tesla results filed with the SEC, 22 July 2026).
Why we file it. Tesla is putting real money into self-driving cars and robots.
How we read it. Tesla's own figures: capex also covers batteries, solar and chips. Tesla says negative free cash flow was driven by a $3.3 billion rise in capex from the prior quarter.
Why it matters to you: self-driving cars and robots are moving toward factory production, and the bill is large.
What this doesn't prove
Tesla's own figures: installed Cybercab capacity of more than 125,000 a year is not the current production rate. Capex also covers non-AI builds. First Optimus builds are for internal training data.
