OpenAI confidentially filed for a U.S. IPO (Initial Public Offering) yesterday, targeting a valuation of up to $1 trillion.
OpenAI, the creator of ChatGPT, is set for a stock market debut, which could come in September, intensifying competition for investor capital, especially as rival Anthropic aims to go public this year as well.
OpenAI did not disclose the size or terms of the offering, and said a timeline has not yet been determined.
“It may be a while because there are things we want to do that are likely easier as a private company,” it said in a statement.
At the mentioned valuation, OpenAI would be the third trillion-dollar-valuation company (along with SpaceX and Anthropic), testing investor appetite in the most consequential quest for high-growth technology stocks in the last 10 years.
On June 1. Anthropic, the company behind Claude Code, confidentially filed for a U.S. initial public offering, weeks after raising $65 billion in a funding round that valued it at $965 billion.
