Warren Buffett said last weekend that he admires Tesla CEO Elon Musk. And the Berkshire Hathaway CEO believes electric vehicles will bring big changes to the auto market. But he doubts any carmaker will be able to hold a dominant position.

“You will see a change in the vehicles, but you won’t see anybody that owns the market because they changed the vehicle,” Buffett said last weekend at Berkshire Hathaway’s annual conference. The investing legend and his partner, vice chairman Charlie Munger, shared their thoughts on EVs and the auto industry in general during a Q&A session.

“The electric vehicle is coming big time, and that’s a very interesting development,” said Munger. But, he added, “at the moment, it’s imposing huge capital costs and huge risks—and I don’t like huge capital costs and huge risks.”

“Charlie and I for long have felt that the auto industry is just too tough,” Buffett said. “It’s just a business where you’ve got a lot of worldwide competitors, they’re not going to go away. And it looks like there are winners at any given time, but it doesn’t get you a permanent place.”

In February, Musk answered a Twitter user’s question about what Berkshire Hathaway should invest in, writing, “Starts with a T…”

Musk added, “Munger could’ve invested in Tesla at ~$200M valuation when I had lunch with him in late 2008.” Tesla’s market cap is now about $530 billion.

The Berkshire Hathaway conglomerate includes all kinds of companies—Duracell, Dairy Queen, and Fruit of the Loom are among the brands under its umbrella—but Buffett and Munger have never been especially enthusiastic about carmakers. It does own General Motors shares and one of the largest car dealers in the U.S., Berkshire Hathaway Automotive.

And in China, Berkshire Hathaway has invested in Tesla rival BYD. Earlier this year, Munger said it’s “almost ridiculous” how much BYD was beating Tesla in China, and he called BYD his best investment at Berkshire Hathaway. Musk has unleashed a price war in China.

Musk has also slashed Tesla prices in the U.S., forcing rivals to follow suit. Ford, for example, this week announced price cuts for the Mustang Mach-E, the bestselling EV last year not built by Tesla. That marked the second time this year that Ford cuts costs after Tesla did so.

Musk warned on an April 19 earnings call that he might be prepared to accept zero profit per vehicle sold, drawing swift backlash from investors worried about a damaging race to the bottom.

Buffett did express confidence in one carmaker last weekend. “I would say Ferrari is in a special place, but they only sell 11,000 or 12,000 cars a year,” he said. According to Reuters, the Italian luxury sports car maker reached 13,221 deliveries in a strong 2022.

“I think I know where Apple’s going to be in 5 or 10 years,” Buffett added, but “I don’t know what the car companies are going to be in 5 or 10 years.”
