The AI wars are heading to Wall Street. Anthropic, creator of the Claude chatbot, is reportedly preparing for one of the largest initial public offerings in history. The startup has engaged a high-profile law firm for a potential listing as early as next year, sparking a race to market with chief rival OpenAI. This development comes as Anthropic pursues private funding that could value it over $300 billion, backed by giants like Microsoft and Nvidia. While the company calls the talks preliminary, the potential listing presents a key test of investor appetite for expensive, loss-making AI firms. Investors see it as a chance for Anthropic to seize the initiative from OpenAI.
