OpenAI Explores IPO as Brockman Says Stake Nears $30 Billion

aibusinesslaw 16 posts · 8 accounts

OpenAI co-founder and President Greg Brockman testified that the company is exploring an initial public offering and that his stake in the ChatGPT maker is now worth nearly $30 billion. OpenAI last raised money at an $852 billion valuation, Brockman said, making him one of the larger individual shareholders in the company.

Under questioning by Musk's attorney, Brockman said Musk was never directly informed that Sam Altman gave him a $10 million stake in Altman's family office in 2017. He was also pressed on whether he had a conflict while advocating for OpenAI to acquire or merge with Cerebras, an AI chip company in which he was an investor, and on 2017 journal notes that described converting OpenAI to a for-profit without Musk's knowledge as pretty morally bankrupt. Brockman said he disclosed the Cerebras investment to colleagues and testified that the conversion would still serve OpenAI's mission.

@garymarcus

The case against OpenAI is getting markedly stronger now that Musk is off the stand. Why? Musk’s lawyer is interrogating OpenAI founder Greg Brockman, making clear that OpenAI sold its mission as a nonprofit for public benefit, and not ju

@garymarcus

Wow. Greg Brockman had a 10M side deal with Altman even in the early nonprofit days, which not disclosed to Elon or (I believe) in nonprofit filings to the company.

@garymarcus

Musk’s lawyer is calmly eviscerating OpenAI’s President Greg Brockman, largely using Brockman’s own diaries and emails. For the first time I think Elon has a real chance of winning.

@garymarcus

Greg Brockman just confirmed what I speculated in December 2023! Sam Altman was not fully candid in his testimony to the US Senate.
