The release of chatbot Claude propelled Anthropic ahead in the AI race. The company's annualized revenue soared from $9 billion in 2025 to over $47 billion in May.

The Anthropic IPO, and those of other AI-related firms like OpenAI, could be among the biggest in U.S. history.

OpenAI has joined the IPO frenzy after rival Anthropic announced plans to go public and ahead of the massive SpaceX market debut this week.

ChatGPT maker OpenAI filed preliminary paperwork that would open the door to it becoming a publicly traded company, making itself the third in a powerhouse trio of artificial intelligence companies racing to Wall Street debuts.
