Anthropic is an artificial intelligence company that has grown extremely fast. According to the New York Times, the company is on track to bring in more than $100 billion in annualized revenue this year—meaning that's the rate at which it's earning money. That's a huge number and shows how valuable the company has become.
The company is preparing to go public, which means it will offer shares (pieces of ownership) to everyday investors through the stock market. This could happen as soon as November. When companies go public, they usually rise in value significantly, and executives and early investors can sell their stakes and make money. For Anthropic's employees and backers, this is a major milestone.
