Tesla Q3 Net Income Plunges 43% as AI R&D Costs Surge; Musk Admits Optimus Mass Production Delayed
Tesla's Q3 profits dropped sharply due to increased spending on AI and robotics, while CEO Elon Musk acknowledged that reaching targeted Optimus production rates will take at least a year.
U.S. electric vehicle maker Tesla reported its third-quarter 2026 financial results, showing a roughly 43% year-over-year decline in GAAP net income attributable to common stockholders, falling to $787 million. While revenue remained stable at $28.05 billion, a sharp increase in operating expenses significantly compressed margins. Research and development costs surged to $2.76 billion from $1.63 billion in the same period last year, an increase of over 69%. Tesla attributed this rise to spending on "Super Intelligence" projects, other development initiatives, and higher stock-based compensation.
CEO Elon Musk used the analyst call to highlight the company's humanoid robot, Optimus. He claimed that early production has begun at the Fremont factory, with most equipment installed to support a nominal capacity of one million robots per year. However, Musk admitted that reaching the target rate of 20,000 units per week would "probably take at least a year, maybe a little longer." He cited changing hand designs, supply chain construction, and robot reliability as key bottlenecks. Tesla did not disclose current weekly production numbers, external customers, or unit costs for Optimus.
Operating margin fell from 5.8% to 2.6%. Non-operating factors distorted the bottom line: unrealized gains of $288 million from Bitcoin holdings were offset by $142 million in unrealized losses from SpaceX equity. Excluding these items and stock-based compensation, Tesla reported an adjusted profit of $1.70 billion, a 4% decline. Free cash flow halved to $3.3 billion over the past twelve months, while capital expenditures rose from $8.9 billion to $15.4 billion, reflecting heavy investment in autonomous driving and robotics without immediate returns.
