According to a public court document filed on November 14, Elon Musk vetoed OpenAI's ICO plan in 2018. The document shows that Musk and his legal team said that in early 2018, OpenAI's two founders, Sam Altman and Greg Brockman, wanted to launch tokens to help the company make money, but Musk believed at the time that this would only lead to a significant loss of credibility for OpenAI and everyone associated with the ICO.
OpenAI was originally a non-profit organization. Musk joined OpenAI as co-chairman of the board of directors and invested $44 million in the startup. Musk even suggested merging OpenAI with Tesla to solve the funding problems of the artificial intelligence startup. However, Musk left OpenAI in February 2018 and founded his own artificial intelligence company, xAI. (The Block)
