ChatGPT maker is expected to be valued at more than $850bn

OpenAI has filed confidentially to go public on the US stock market, according to a company blog post published Monday. The ChatGPT maker is expected to be valued at more than $850bn. “We recently submitted a confidential S-1. We expect it to leak so we’re just announcing it. We have not decided on timing yet; it may be a while because there are things we want to do that are likely easier as a private company. But it’s a complicated set of tradeoffs and this gives us the option to go public sooner if that ends up being best,” the company’s post reads. An S-1 is an investor prospectus submitted to the US Securities and Exchange Commission (SEC) in advance of an initial public offering (IPO). One week earlier, OpenAI’s rival Anthropic, which makes the popular Claude chatbot, announced it had filed to go public with the SEC. More details soon…
