Tesla beats forecasts, but profit falls 43% as money flows into AI and robots

Where Tesla makes money. Cars brought in $20.56 billion, 3% less than a year ago: fewer cars sold, lower average prices and almost no income left from selling regulatory credits. Energy, meaning home and grid batteries, fell 16% to $2.88 billion, partly because of tariff-related refunds to customers. Services, charging, insurance and parts grew 33% to $4.61 billion.

Where the money goes. Operating expenses rose 39% to $4.78 billion. Research and development cost $2.76 billion. Capital spending was $4.73 billion, up from $2.25 billion a year ago. Free cash flow turned positive again at $1.53 billion after a negative second quarter. Tesla holds $45.4 billion in cash and investments.

Why sales are stuck. Tesla says battery supply is still the main limit on how many cars it can build. It delivered 486,532 cars in the quarter, 2% fewer than a year ago. Active FSD driver-assist subscriptions reached 1.74 million, up 67%. Its Austin robotaxis have driven nearly 2 million miles with no one behind the wheel, and Cybercabs joined the fleet on 3 September.

Bitcoin and SpaceX. Profit includes paper moves: Tesla's bitcoin gained $288 million in value, while its SpaceX stake lost $142 million. A day before the report, Musk said on SpaceX's call that merging the two companies would be a good idea, and both boards have set up special committees. Nothing is decided.

Implications

• ConfirmedTesla is spending much more on AI, robots and factories than a year ago, and that is weighing on profit.
• Our readingUntil the battery shortage eases, car sales are unlikely to grow quickly.
• Our readingTesla's share price depends more and more on robotaxis, Optimus and the SpaceX story rather than car sales.

Still unknown

• What Tesla will say about spending plans for the fourth quarter and 2027.
• When the battery shortage will end.
• Whether a SpaceX merger happens, and on what terms.
