Nasdaq rises 1.3% as AI-linked stocks gain; Nvidia up 3.1%

The move shows AI enthusiasm is still the market's primary risk-on trigger, with the semiconductor complex outperforming the broader indices by a wide margin. Anthropic's IPO filing is being read as validation of the AI trade's depth, lifting chip suppliers and hyperscalers alike rather than any single name. It also highlights how concentrated sentiment has become around AI-linked equities, where a single filing can move an entire index. Whether the semiconductor index's outsized gain holds once the filing's details are digested, and whether the rally broadens beyond AI names, is the open question.
