Revenue Roughly Flat, but Profit Slumps
Tesla's third-quarter automotive revenue fell 3% year-over-year to $20.560 billion. Deliveries during the period fell 2% to 486,532 vehicles, while production rose 4% to 464,391 vehicles.

Services and other revenue grew 33% to $4.605 billion, with gross profit reaching a record $734 million.
Profit pressure came mainly from operating expenses below the gross profit line. Third-quarter operating expenses rose 39%, driven primarily by R&D spending, which climbed from $1.63 billion a year earlier to $2.76 billion.
In addition, regulatory credit revenue fell about 73% year-over-year, further weighing on the company's profitability.
GAAP net income attributable to common stockholders was $787 million, including a $142 million pre-tax unrealized loss on Tesla's equity investment in SpaceX and a $288 million pre-tax unrealized gain from digital assets.
Cash Flow and Capital Expenditure
Tesla's third-quarter operating cash flow was $6.263 billion, capital expenditure was $4.732 billion, and free cash flow reached $1.531 billion.
Cash, cash equivalents and investments increased by $1.9 billion during the quarter, bringing the total to $45.447 billion.
On the earnings call, CFO Vaibhav Taneja said Tesla now expects 2026 capital expenditure of about $20 billion, below its previous guidance of more than $25 billion.
He said the company plans to fund the related spending primarily through operating cash flow.
Robotaxi, Optimus and Future Development
Cybercab began carrying passengers in Austin on September 3. Tesla said cumulative miles driven by its unsupervised Robotaxi fleet grew eightfold quarter-over-quarter, approaching 2 million miles.
Optimus has started production on a high-volume line in Fremont, and a dedicated Optimus production facility in Texas is under construction.
CEO Elon Musk said on the earnings call that it will take at least another year, and possibly longer, for Optimus to reach a production rate of 20,000 units per week.
Tesla Semi has begun scaled production in Nevada, and the company also plans to boost AI training compute to 400 MW by the end of the year.
Tesla said it is currently focused on raising factory capacity utilization, but battery supply remains one of the factors limiting vehicle production.
