Tesla Q3 profit falls 43% as capital spending rises

Tesla released its third-quarter results on October 21, 2026.[1] Revenue was $28.046 billion, essentially unchanged from a year earlier, while GAAP net income fell 43% to $787 million.[2] Operating income declined 56% to $718 million.[2] The results show a gap between stable top-line revenue and weaker earnings, even as Tesla’s GAAP gross margin rose 160 basis points year over year to 19.6%.[2] For readers assessing the quarter, the different directions of revenue, operating income and gross margin matter more than any single headline figure.

Tesla’s Q3 capital expenditures were $4.732 billion, 110% higher than a year earlier.[2] Separately, Bloomberg reported that Tesla lowered its capital-expenditure plan for the year to about $20 billion after previously raising its target to more than $25 billion.[3] The quarterly increase and the revised annual plan describe different time frames; the evidence does not identify the spending as AI-chip investment. Tesla reported $45.447 billion in cash, cash equivalents and short-term investments at quarter-end, up 9% year over year.[2] The company said it continued investing across its businesses through R&D and Capex.[2]

Tesla said it began providing Robotaxi rides using Cybercabs in Austin on September 3, and that cumulative unsupervised Robotaxi miles grew eightfold quarter over quarter.[2] It also said Optimus production began on high-volume lines in Fremont, with the first production-quality robots coming off the line.[2] The company said its Texas Megafactory began production with planned capacity of 50 GWh, and that volume production of the Class 8 Tesla Semi began.[2] Tesla also said it ended Q3 with its largest passenger-vehicle backlog in four years.[2] These are company-reported milestones; the results provided here do not establish their future financial contribution.

CNBC reported adjusted Q3 earnings per share of 48 cents, above analysts’ 43-cent estimate, and revenue of $28.05 billion, above the $27.9 billion estimate.[4] Tesla shares nevertheless fell more than 3% in extended trading after the earnings report.[4] CNBC also reported that the shares were down 14% for the year and lagging other megacap technology stocks.[4] These figures offer context for the immediate market response, but they do not explain why investors traded the shares lower. The reported estimate comparisons use adjusted earnings per share, while the $787 million net-income figure is GAAP.[2][4]
