Is ChatGPT available for public trading on the stock market?

As of the most recent information available, ChatGPT itself is not a standalone entity available for public trading on the stock market. Rather, it is a product developed by OpenAI, which is a private artificial intelligence research lab and technology company. OpenAI has not gone public, meaning its shares are not listed on any stock exchange for public investors to buy and sell. Thus, individuals interested in investing in OpenAI or its technologies like ChatGPT would need to explore other avenues, typically through private funding rounds that are generally accessible to venture capitalists and accredited investors.
