The outlook for artificial intelligence platform OpenAI’s initial public offering is changing following a New York Times report that the company may delay its public market debut until next year.
So when will the company officially announce its IPO? Traders at prediction market platform Karshi think it will arrive early next year.
Speculators say there is a 59% chance that OpenAI’s IPO will be officially announced by March 1, 2027. Traders say there is only a one in three chance that an IPO will be announced by January 1st, but they believe there is a 73% chance that it will be announced by June 2027.
Kalsi considers an IPO to be final and resolves the contract to “yes” if any of the following occurs: the Securities and Exchange Commission declares the company’s S-1 Form effective, the IPO has a formal price, or the company receives a trading ticker.
OpenAI was previously widely expected to IPO in 2026, with the company led by CEO Sam Altman secretly filing to go public on June 8th.
The New York Times said Open AI’s advisors have become more cautious following SpaceX’s public market debut, the first of several expected blockbuster IPOs this year. Open AI is concerned that Elon Musk’s company’s initial rally and subsequent decline may indicate that retail investors are less willing to buy, the report said.
In early June, OpenAI’s biggest rival, Anthropic, secretly filed for an IPO. Kalsi traders believe there is a 70% chance that Anthropic will formally announce its public market debut by December.
