OpenAI has confidentially filed for a US IPO and is reportedly targeting a valuation of up to $1 trillion, according to reports.
The ChatGPT maker closed its most recent funding round at $122 billion in committed capital at an $852 billion post-money valuation in April 2026, and serves more than 900 million weekly active users.
The listing would follow rival Anthropic’s IPO filing and could become one of the most consequential technology market debuts in a decade.
The race to dominate artificial intelligence is moving from private markets to public ones, and both of the world’s leading AI companies are filing for IPOs within weeks of each other.
OpenAI, the company behind ChatGPT, confidentially filed its S-1 with the SEC in May 2026. Sam Altman is reportedly targeting a debut at a valuation between $852 billion and $1 trillion, with Goldman Sachs and Morgan Stanley leading the deal.
