OpenAI Files for U.S. IPO After Anthropic's Big Move
OpenAI has officially filed confidential paperwork for the U.S. Initial Public Offering (IPO), marking a historic step toward letting the public buy shares in the creator of ChatGPT.

OpenAI has officially filed confidential paperwork for the U.S. Initial Public Offering (IPO), marking a historic step toward letting the public buy shares in the creator of ChatGPT. The surprise announcement on June 8, 2026, came just days after its main competitor,Anthropic, also filed for its own stock market debut. These simultaneous moves signal that the world's most powerful artificial intelligence companies are rapidly heading to public financial markets.
OpenAI will be making history with an unprecedented valuation: last time, they were aiming for a $500 billion valuation, but now they are raising it to $1 trillion. This could become one of the largest technology IPOs ever. The rival model Claude, which is made by Anthropic, will be chasing a similar amount of $965 billion valuation. Both firms are competing in the massive race for high-profile tech listings on the stock market, alongside Elon Musk’s SpaceX.
Building and maintaining the artificial intelligence model requires an enormous amount of money. Experts say that OpenAI has spent over $100 billion a year on advanced data centers and computing power.
By offering shares to ordinary public investors, these AI companies hope to secure billions of dollars in fresh cash to stay ahead in the global tech race. Going public will also force these famously secretive tech giants to share regular reports about their profits, losses, and future product plans with regular shareholders.
Before this filing, OpenAI cleared a major legal hurdle in May 2026 when a U.S. jury rejected a lawsuit from early backer Elon Musk, who had accused the firm of abandoning its original humanitarian mission. This victory reassured investors who were worried about legal risks. While OpenAI has confirmed the confidential submission, it has not finalized the exact date for when its stock will begin trading on the stock exchange, preferring to keep its options flexible as market conditions evolve.
