OpenAI announced on social media that it has confidentially filed for a US initial public offering (IPO), becoming the third major AI company to pursue a public listing this year, following Anthropic and SpaceX. The company has not yet determined a timeline for its market entry, stating that it may be a while before it goes public due to ongoing developments that are easier to manage as a private entity. CEO Sam Altman has previously suggested that an IPO is the company’s most likely path, primarily due to the substantial capital required for further AI advancements. Analysts have noted that OpenAI is facing stiff competition from companies like Google and Anthropic, which may jeopardize its early advantages in the AI sector. The timing of the IPO filing is viewed as precarious by some analysts, who emphasize the need for significant capital to support the company's operations. Meanwhile, Anthropic recently filed for an IPO and is valued at approximately $965 billion, while SpaceX is also moving forward with its IPO plans, potentially setting a record for the largest IPO if successful.
