OpenAI IPO valuation, filing details and expected share price: The race to own a piece of the AI revolution just got a lot more real. OpenAI, the company behind ChatGPT and arguably the most recognized name in artificial intelligence, has filed a confidential S-1 registration statement with the U.S. Securities and Exchange Commission — the first formal step toward an OpenAI IPO that Wall Street has been anticipating for years.
The OpenAI IPO filing arrives at a moment of fierce competitive pressure, surging valuations, and unresolved questions about whether any AI company can justify what the market is willing to pay. With a post-money valuation of $852 billion following its March 2025 funding round, OpenAI is not just entering the public markets — it is arriving as one of the most valuable companies ever to attempt the leap. The timing matters enormously.
