AI Warnings Could Signal End to Hyperscaling -- Market Talk

0913 GMT - Safety warnings about artificial intelligence could signal the end of precipitous growth in compute and AI infrastructure investments, XTB's Kathleen Brooks writes. Leaders of Anthropic, OpenAI and SpaceX all called for a slowdown in AI model development, "a highly unusual unified message," Brooks writes. The call could signal an end to hyperscaling, which would have massive repercussions for financial markets, Brooks says. Over half of the sectors that constitute the S&P 500 are linked to AI, while hyperscalers make up a third of the weighting of the blue-chip index, Brooks notes. S&P 500 futures fall 0.7%, while futures for the tech-heavy Nasdaq drop 1.75%. (josephmichael.stonor@wsj.com)
