Asian equity markets opened sharply lower on Friday, with semiconductor names leading the decline as the region’s artificial intelligence-driven rally encountered severe headwinds.

Taiwan Semiconductor Manufacturing Company (TSMC) shares fell 7%, while Japanese flash memory specialist Kioxia Holdings plunged 16%, signaling deepening distress in the hardware supply chain.

South Korea’s benchmark Kospi index had already plummeted as much as 8% on Thursday, marking the sharpest single-day decline in the region’s AI trade to date.

The sell-off represents a continuation of the volatility that erupted earlier in the week.

Kioxia’s steep drop is particularly notable given the company’s recent trajectory.
