Tesla CEO Elon Musk vetoed OpenAI's ICO plan in 2018, arguing it would damage the company's credibility, according to WuSay. He had disagreements with founders Altman and Brockman.

Musk proposed merging OpenAI with Tesla to solve funding problems, but eventually left in February 2018 and founded xAI. Since then, he has sued OpenAI and its senior management, accusing them of fraud and unfair competition, and the lawsuit also involves Microsoft's investment.

Meanwhile, Ultraman-backed Worldcoin launched the WLD token in 2023.
