Anthropic IPO filing lifts copper prices as AI stocks rebound

Copper prices rebounded above key support on Tuesday, tracking a recovery in AI stocks following Anthropic's public IPO filing. The metal, which had broken below its April trendline during a tech selloff last week, rose on data linking new AI infrastructure to copper demand. Analysts note that while warehouse stocks in the U.S. are piling up, tight global supply, particularly in China, may limit further price gains.
