Global market brief: AI hardware slumps premarket, Panasonic CCL plant fire

The simultaneous pressure on AI hardware equities and a fire at a key Panasonic copper-clad laminate plant highlights how concentrated the AI supply chain remains in a handful of specialized component makers. Optical names and Qualcomm's premarket drop suggest sentiment is fragile, but the CCL disruption is the more tangible risk: it touches the physical substrate layer that AI infrastructure buildouts depend on, and a 4% hit to high-end supply could ripple through lead times. Microsoft's reported order cancellation and OpenAI's data center shift add demand-side uncertainty. Whether the supply event proves transient or compounds into broader hardware tightness is the open question.
