Elon Musk ordered Nvidia to ship thousands of AI chips reserved for Tesla to X and xAI

Elon Musk says he can grow Tesla into "a leader in AI & robotics," an ambition that he's said will require a lot of pricey processors from Nvidia to build up its infrastructure.

On Tesla's first-quarter earnings call in April, Musk said the electric vehicle company will increase the number of active H100s — Nvidia's flagship artificial intelligence chip — from 35,000 to 85,000 by the end of this year. He also wrote in a post on X a few days later that Tesla would spend $10 billion this year "in combined training and inference AI."

But emails written by Nvidia senior staff and widely shared inside the company suggest that Musk presented an exaggerated picture of Tesla's procurement to shareholders. Correspondence from Nvidia staffers also indicates that Musk diverted a sizable shipment of AI processors that had been reserved for Tesla to his social media company X, formerly known as Twitter.

Tesla shares slipped as much as 1% on the news Tuesday morning.

By ordering Nvidia to let privately held X jump the line ahead of Tesla, Musk pushed back the automaker's receipt of more than $500 million in graphics processing units, or GPUs, by months, likely adding to delays in setting up the supercomputers Tesla says it needs to develop autonomous vehicles and humanoid robots.

"Elon prioritizing X H100 GPU cluster deployment at X versus Tesla by redirecting 12k of shipped H100 GPUs originally slated for Tesla to X instead," an Nvidia memo from December said. "In exchange, original X orders of 12k H100 slated for Jan and June to be redirected to Tesla."

A more recent Nvidia email, from late April, said Musk's comment on the first-quarter Tesla call "conflicts with bookings" and that his April post on X about $10 billion in AI spending
