Anthropic IPO Filing Boosts AI Stocks, Drives S&P 500 and Nasdaq Gains

Anthropic’s filing for a U.S. initial public offering lifted sentiment in AI‑related shares, helping the S&P 500 rise 0.7 % to 7,676 and the Nasdaq climb 0.8 % to 26,169. The disclosure of steep losses alongside rapid revenue growth underscored the company’s ambition to build AI systems that could reshape the global economy, even as development costs remain high. Semiconductor and chip‑related firms, seen as major beneficiaries of the AI boom, pushed the indices higher, while neo‑cloud companies such as CoreWeave erased earlier declines. Meta announced plans to raise up to $95 billion in equity to fund AI‑driven data‑centre expansion, and Tesla surged 5.2 % after a Barclays rating upgrade. The market is now poised for the Federal Reserve’s policy statement, U.S. economic data, and a week of corporate earnings, including those of Alphabet, Microsoft and Amazon, which will test whether AI spending translates into growth.
