CoreWeave jumps ~17% premarket on Q3 revenue beat, raised full-year guidance

The read-through here matters more than the beat itself: a raised outlook from CoreWeave is being treated as a demand signal across the AI supply chain, lifting memory and optical names alongside it. That breadth suggests the market is pricing AI infrastructure spending as durable rather than a single-quarter blip, which affects adjacent hardware suppliers as much as CoreWeave. The open question is whether this sympathy rally holds once the premarket move fades, or whether it reflects a broader re-rating of AI capex expectations.
