OpenAI co-founder and president Greg Brockman said on Monday that the company's business growth momentum is strong, with annualized revenue increasing by 20% month-over-month in July, and enterprise customer growth reaching 32%. He also confirmed that OpenAI confidentially submitted its IPO prospectus to the U.S. Securities and Exchange Commission (SEC) in June. The company is currently valued at $852 billion, and its IPO is widely expected to be one of the largest tech stock listings in recent years.
