Anthropic IPO filing sparks Asian stock rally, except in China

Anthropic's filing for an Initial Public Offering (IPO) has spurred a rally in Asian stock markets, particularly in South Korea and Japan, boosting shares in AI, tech, and semiconductor companies. The company disclosed significant first-half revenue and a narrower operating loss in its S-1 filing with the SEC, aiming for a valuation between $1.5 trillion and $2 trillion on the Nasdaq. While most of Asia saw gains, Chinese stocks underperformed, with major tech and semiconductor firms experiencing declines, attributed to their exclusion from the primary U.S. AI supply chain and export controls.
