OPENAI QUIETLY FILES CONFIDENTIAL IPO PAPERWORK AND LOCKS IN GOLDMAN SACHS AND MORGAN STANLEY FOR A SEPTEMBER WALL STREET DEBUT AT ONE TRILLION DOLLARS Sam Altman’s OpenAI filed a confidential draft S-1 registration statement with the Securities and Exchange Commission on May 22, targeting a public market debut as early as September 2026. Goldman Sachs and Morgan Stanley are leading the underwriting process. The company’s current private market valuation sits near $852 billion, and analysts advising on the deal expect the listing to push OpenAI past a one trillion dollar market capitalization. The filing came days after Anthropic made its own confidential IPO submission, turning the fall of 2026 into what looks like the most consequential AI listings season in market history. Two companies that barely existed in meaningful form five years ago are now racing to become trillion-dollar publicly traded entities within months of each other. OpenAI went from near-bankruptcy rumors in 2022 to the most anticipated Wall Street debut since Facebook’s 2012 listing. For public investors who have had zero access to the AI boom despite it generating the largest wealth transfers in tech history, these IPOs represent the first real chance to own a stake in the models reshaping every industry. The September timeline is aggressive. Between regulatory review, roadshow preparation, and the summer trading window, the margin for error is thin. But Altman has moved fast before. The question now is whether a one trillion dollar valuation is the ceiling or the floor. Keywords: OpenAI IPO, Goldman Sachs AI, OpenAI stock market listing, AI company valuation 2026
