While there have been discussions and speculation about a potential future IPO (Initial Public Offering), OpenAI has not announced any plans to go public. Its value is primarily derived from its partnerships with companies like Microsoft, which has invested heavily in the company and utilizes OpenAI's technology in its products. Investors interested in gaining exposure to OpenAI's technology may look to invest in companies with close ties to the organization, like Microsoft.
