OpenAI IPO: The most consequential IPO race in stock market history is unfolding in real time. On May 20, 2026, reports confirmed that OpenAI is preparing to file a confidential IPO prospectus as soon as this Friday — the very same day SpaceX is expected to release its own public S-1 filing to investors. Two trillion-dollar AI companies. One week. A market that has never seen anything like this before.
Goldman Sachs and Morgan Stanley are handling both offerings — a fee concentration with no modern precedent in equity capital markets history. OpenAI is targeting a public debut by September 2026, eyeing a valuation north of $1 trillion.
