ChatGPT creator OpenAI is preparing a confidential initial public offering filing for submission as early as this week. The company is drafting its prospectus with Goldman Sachs and Morgan Stanley.

Reports suggest a potential public listing in the fourth quarter of 2026. A March 2026 funding round valued the company at $852 billion.

OpenAI targets an IPO valuation of approximately $1 trillion. This debut would rank among the largest in market history. The company recently restructured into a for-profit entity to facilitate the offering.
