The stock was trading at $163, dragging down other automakers. At least 15 analysts lowered their price targets on Tesla, whose market value was on track to drop by $50 billion to about $517 billion, if losses hold. That would put Tesla's value below that of Meta Platforms Inc for the first time since 2021.

"Facing a volatile macroeconomic backdrop and weakening demand, Tesla continues to prioritize units over near-term profits," said analysts at Canaccord Genuity.

Tesla's gross margins fell in the first quarter to the lowest in more than two years, missing market estimates, after the company kicked off a global price war in January to defend its dominance in the U.S. and make inroads in China, its second-largest market.

Tesla's automotive gross margin, excluding regulatory credits and leasing, stood at 18.3%, missing the above 20% target provided in January by Tesla CFO Zachary Kirkhorn.

Tesla has already slashed prices six times this year and Musk suggested more such moves ahead, saying the company will put sales growth ahead of profit in a weak economy.

"We've taken a view that pushing for higher volumes and a larger fleet is the right choice here versus a lower volume and a higher margin," he said.

Investors dumped automakers from Europe to the United States on fears that margins will be sacrificed for maintaining share in a market that is slowing.

"Long-term we believe this (Tesla's price cuts) is the right strategy and leverages their cost leadership position. However, this does not come without pain as we now believe margins will get worse before they get better," RBC analyst Tom Narayan said.

U.S. automakers ranging from Ford Motor Co. to startups such as Lucid Group Inc. fell between 3.3% and 4.4%.

France-based Renault SA, whose finance chief said the company will not drastically cut prices on its EVs amid Tesla's downward "spiral," was down 7.6%, while Germany's Volkswagen fell 3.5%.
