OAKLAND, Calif. — OpenAI’s president Greg Brockman detailed a wild meeting in 2017 with Elon Musk in which the co-founders tussled over ownership stakes in the company – at one point claiming that he feared Musk “was going to physically attack me.”

Testifying on Tuesday in the second week of the bombshell trial over the future of OpenAI, Brockman claimed Musk showed up to meet him along with other OpenAI top brass to negotiate their equity stakes in the for profit company that would eventually launch ChatGPT.

In the middle of talks, Brockman said Musk personally gifted free Teslas to him, Ilya Sutskever and others — a move Brockman saw as Musk “buttering us up” and to make the co-founders feel “indebted to him in some way.” Likewise, Sutskever had given Musk a painting of a Tesla car, Brockman said.

But when the OpenAI co-founders rebuffed Musk’s demand for a majority stake in the company — with Musk claiming he needed $80 billion to create a city on Mars — Musk went ballistic, according to Brockman.

“Something really shifted in him,” Brockman said of Musk. “He became angry and he went off from there.” OpenAI’s Brockman details wild meeting with Elon Musk: ‘I thought he was going to physically attack me’

“He stood up and he stormed around the table,” Brockman continued. “I was sitting in front of the painting and I actually thought he was going to hit me. I truly thought he was going to physically attack me. Instead, he just grabbed the painting and started to storm out of the room.”

Musk then demanded to know when the group would leave OpenAI — and declared that he’d withhold funding until they did.
