Many big AI companies are moving toward stock market listings this year. They want more money to build AI systems and to stay ahead in the race.

People are excited about AI, and stock prices have gone up. But some experts worry that too much money is going into a new and unproven field.

SpaceX, owned by Elon Musk, may have one of the biggest IPOs ever. The company was valued at $1.25 trillion after it merged with Musk’s AI company, xAI, in February.

Anthropic, the maker of Claude, said it filed secret IPO papers with the U.S. Securities and Exchange Commission. It was recently valued at $965 billion and said it makes $47 billion a year.

OpenAI, the maker of ChatGPT, is valued at $852 billion and may go public as soon as this fall. Google’s parent company, Alphabet, and Meta are also spending a lot on AI, while Microsoft has used its investment in OpenAI to help build Copilot.
