Here’s how much OpenAI stock would be worth in IPO

On December 18, it was reported by The Wall Street Journal that OpenAI was seeking to raise another $100 billion in funding, which would effectively bring the company’s valuation to $830 billion and maybe lay the groundwork for a potential OpenAI stock IPO. 

Right now, OpenAI controls around 17% of the global chatbot market thanks to its flagship product, the ChatGPT series, which has numerous use cases on developer platforms and day-to-day applications. 

While the funds are primarily needed to further scale the AI leader’s efforts and ensure it remains competitive, it has also led to a lot of speculation as to whether CEO Sam Altman might be looking to go public in the near future.

However, with the management aiming to close the funding round by as late as March 2026 and there being no guarantee that investors will fly in at the targeted scale, it is still hard to give a precise figure as to what price OpenAI stock would trade at upon IPO. 

Nevertheless, Finbold decided to ask OpenAI’s own large language model (LLM), ChatGPT-5, to see what its thoughts were regarding a potential OpenAI stock price during an initial public offering, assuming it does come next year once the recent funding plans have been realized.

In response to the inquiries, the chatbot first noted that the $100 billion in fresh private funding by March 2026 would likely reinforce a higher public-market valuation. Accordingly, it argued for a figure in the $900 billion to $1.05 trillion range (one of the largest IPOs in history). 

The public float, ChatGPT continued, is likely to be 12%–15%, with 15% being most likely in order to ensure adequate liquidity and meet investor demand. Overall, this implies the IPO would raise another $150 billion at a $1 trillion valuation.

However, the analysis also came with a slight caveat, namely that a substantial pre-IPO private raise could result in some dilution for existing shareholders. Still, it can be argued that share prices will ultimately be less meaningful than overall market capitalization, as the final per-share figure will depend on OpenAI’s total share count at listing. 

Asked to predict more specific prices, ChatGPT estimated OpenAI stock prices of no less than $2,000 per share at $1 trillion valuation, assuming a hypothetical 500 million shares outstanding. At $900 billion, the price would sit at around $1,800, while at $1.05 trillion, it might go up to $2,100.

In conclusion, the chatbot reminded that numbers must be taken with a grain of salt, as the real number could change the OpenAI share price dramatically. Similarly, large-scale funding rounds could dilute early investors, altering ownership percentages and market perception heading into the IPO.
