Anthropic told investors recently that the company's revenue for the third quarter jumped about 45% from the prior quarter to $16.8 billion. The AI lab is currently pursuing what may become the largest-ever initial public offering. Its IPO could value the company at $2 trillion. The San Francisco company is expected to begin trading as early as next month. A successful launch from Anthropic could reopen the door for other listings and provide a vote of confidence for the industry.
