Tesla Operating Income Plunges 56% as AI Spending Outpaces Profit

Tesla reported a 56% drop in operating income for the third quarter, a figure that underscores the financial strain of the company's rapid expansion into artificial intelligence and robotics. The automaker posted $718 million in operating income for the period, a steep decline from $1.63 billion a year earlier. This came as research and development costs surged 69% to $2.76 billion, driven by investments in what the company calls “Super Intelligence,” its Optimus humanoid robot, and the Cybercab.

For the quarter ended September 30, 2026, Tesla's revenue was $28.05 billion, effectively flat compared to $28.1 billion in the third quarter of 2025. The figure was in line with Wall Street's consensus estimate of $28.06 billion. On a non-GAAP basis, earnings per share were $0.48, beating the $0.45 analyst forecast but down 4% from $0.50 a year ago. Under Generally Accepted Accounting Principles (GAAP), net income fell 43% to $787 million, or $0.22 per share.

While the top-line numbers were stable, the report revealed mixed results in other areas. Total gross margin improved to 19.6%, up from 18.0% in the prior-year quarter, and automotive gross margin excluding regulatory credits rose to 18.1% from 16.3% in Q2. However, total operating expenses climbed 39% to $4.78 billion, and capital spending more than doubled to $4.73 billion. The company's financial statements also reflected a $288 million unrealized gain on its bitcoin holdings, which was partially offset by a $142 million unrealized loss on its equity stake in SpaceX.

The results follow a second quarter in which operating margin compressed to 1.4% and earnings per share missed expectations by 20 cents. The focus for analysts heading into Wednesday's report was whether the company could arrest that decline in profitability. The current quarter's results show that while margins have stabilized, the company's spending on future technologies continues to weigh on its operating results, a trend that has persisted throughout the year.

Tesla's capital expenditures for the first nine months of 2026 stand at $13.01 billion, approximately half of the company's full-year guidance for more than $25 billion. To meet that target, Tesla would need to spend about $12 billion in the fourth quarter, a figure more than double its highest-spending quarter so far. The shareholder letter did not update this guidance, and capital spending actually declined sequentially from $5.79 billion in the second quarter.

The company's energy division was a weak point, with revenue falling 16% to $2.88 billion. Tesla attributed part of this decline to customer refunds related to tariffs, despite a 10% increase in energy storage deployments to 13.7 GWh. In contrast, the services segment saw revenue grow 33% to $4.61 billion, with gross profit from charging, insurance, and parts sales reaching a record $734 million.

Tesla stated that battery availability was the primary constraint on increasing vehicle production during the quarter. The company reported that it ended the period with the largest passenger vehicle backlog in four years, though it delivered 22,141 more cars than it produced, reducing its inventory supply to 11 days from 15 days in Q2. Deliveries totaled 486,532 vehicles, down 2.1% year-over-year but ahead of analyst expectations.

On the technology front, Tesla reported that active Full Self-Driving (FSD) subscriptions reached 1.74 million, a 67% increase. The company also stated that its Robotaxi service had accumulated nearly two million unsupervised miles by the end of the quarter. Management was scheduled to discuss these results on an earnings conference call at 5:30 p.m. ET.
