OpenAI is preparing for a significant IPO, aiming to raise $60bn and potentially achieving a valuation of over $1tr. This move marks a shift from its nonprofit origins in 2015. The IPO could be the largest ever, competing with SpaceX's own IPO plans. Despite its ambitions, OpenAI has yet to turn a profit and faces challenges in its business model. The market is eager for AI investments, but uncertainties remain about how these companies will be valued publicly.
