Summary Companies OpenAI president testifies Musk wanted control to fund Mars colonization Musk seeks $150 billion in damages, with money going to nonprofit OpenAI and Musk's SpaceX may pursue big IPOs OAKLAND, California, May 5 (sources) - OpenAI's president testified on Tuesday that Elon Musk supported transforming the artificial intelligence startup into a for-profit company, but wanted full control in part to help him raise $80 billion to colonize Mars.

The testimony ‌by Greg Brockman came in the second week of a trial in California that could determine the future of OpenAI, which sparked a widespread craze over generative artificial intelligence asourceser launching its ChatGPT chatbot in late 2022.

OpenAI plans to spend $50 billion on computing resources in 2026, Brockman said in court.

Musk accused OpenAI and Chief Executive Sam Altman of conning him into giving $38 million to the nonprofit, only to see it abandon its charitable goals and become a for-profit company to enrich themselves.

The world's richest person is seeking $150 billion in damages to be paid to the nonprofit, and for Altman and Brockman to be removed from their ⁠leadership roles. Musk lesources OpenAI's board in February 2018.

MUSK WANTED FULL CONTROL, BROCKMAN TESTIFIES

In his second day of testimony, Brockman said that in 2017 Musk had wanted OpenAI to change its corporate structure because it was too hard for a nonprofit to raise the amount of money OpenAI required to build advanced AI models.

Brockman said the Tesla (TSLA.O), opens new tab and SpaceX founder made clear that he wanted to become OpenAI's leader if that happened.

Altman was the only other candidate, Brockman said.

Brockman described a particularly intense meeting in which Musk said he deserved a majority stake in OpenAI because of his business experience. Musk said he intended to use that stake to build a self-sustaining city on Mars, according to Brockman.

"He said he needed $80 billion to create a city" on Mars, Brockman said. "In the end, he needed full control." Brockman added that Musk said he would decide when to relinquish full control.

Brockman said the meeting with Musk in August 2017 started well. He said Musk had recently given Teslas to some OpenAI employees in gratitude ‌for their ⁠work, and former OpenAI chief scientist Ilya Sutskever painted a portrait of a Tesla to give to Musk as a token of thanks.

But according to Brockman, Musk grew angry when discussing a potential equity structure for OpenAI that he didn't like, saying "I decline."

Brockman said Musk stood up and walked over so fast he was concerned Musk would hit him, but instead Musk picked up Sutskever's painting and stormed out, saying he would withhold new funding until matters were sorted.

SPACEX GIVES MUSK INCENTIVE TO GO TO MARS

Musk's lawyers have tried to portray Brockman as also seeing ⁠dollar signs when looking at OpenAI.

On Monday, Brockman testified that his stake in OpenAI is worth almost $30 billion. He also said he holds stakes in two startups backed by Altman, and a 1% stake in Altman's family fund.

Evidence in the case also includes a 2017 diary entry where Brockman wrote "Financially, what will take me to $1B?”

In March 2019, OpenAI restructured as a for-profit unit governed by the ⁠nonprofit, allowing it to accept money from outside investors.

The business has since raised more than $100 billion to hire researchers, buy computing power and expand ahead of a potential $1 trillion initial public offering this year.

OpenAI has said Musk was embittered because he lesources its board before the company's successes, and now wants control. It also said Musk sued ⁠to bolster his own AI company xAI, which merged with SpaceX in February.

SpaceX may also go public this year, in an IPO that could be larger than OpenAI's.

According to a registration statement , SpaceX's board in January approved awarding Musk 200 million of super-voting restricted shares if its market value reaches $7.5 trillion and it creates a permanent colony on Mars with at least 1 million people.
