Sam Altman’s OpenAI Files For IPO
Today, the Sam Altman-led company wrote, “We recently submitted a confidential S-1. We expect it to leak so we’re just announcing it.” OpenAI added currently they have not finalized the timeline.
Moreover, the firm cautioned that “it may be a while because there are things we want to do that are likely easier as a private company.”

The ChatGPT developer also admitted that there was a nuanced tale to be told about a public launch despite the hype around OpenAI’s IPO. It stated that “it’s a complicated set of tradeoffs and this gives us the option to go public sooner if that ends up being best.”
In the disclosure, OpenAI emphasized it was made pursuant to Rule 135 of the Securities Act of 1933. The firm added that it “does not constitute an offer to sell or the solicitation of an offer to buy any securities.”
The SpaceX & Anthropic IPO Saga
Further, it’s important to note that OpenAI’s disclosure comes amid surging investor interest in high-profile AI and tech firm IPOs. Elon Musk’s SpaceX will close IPO on Wednesday when U.S. markets close. The stock pricing is set to occur June 11 while Nasdaq trading will take place on June 12.
The aerospace and satellite firm of Elon Musk is trying to raise $75 billion at a fixed price, which suggests its valuation is close to $1.75 trillion. The offering is reportedly 2x times oversubscribed as orders have reportedly climbed well above expectations. The overall subscriptions for SpaceX IPO came in at about $150 billion.
SpaceX has also gained some attention in the digital asset space, after revealing that it owns 18,713 BTC. The stash is worth approximately $1.29 billion at present.
Moreover, OpenAI’s announcement comes after another secret filing by AI rival Anthropic earlier this month. The artificial intelligence startup filed paperwork with the U.S. Securities and Exchange Commission to go public on June 1. The filing followed a $65 billion capital raise at a valuation close to $965 billion.
