TSM stock is moving more than 3.7% higher in early trading following reports that Taiwan Semiconductor Manufacturing Company Limited plans to raise chipmaking prices by up to 10% from 2027. The price increase is expected to intensify pressure on Big Tech firms investing heavily in AI infrastructure. Analysts have highlighted TSM’s central role in the AI supply chain, with recent coverage focusing on valuation shifts and the company’s expanding footprint in the U.S.

The stock opened with a 3.7% gap up from the prior close of $402.30, reaching $417.09. The move follows a surge in coverage over the past 36 hours, with 37 stories from 18 sources discussing TSM’s strategic position in the AI ecosystem. Reports from Benzinga and Yahoo highlight TSMC’s planned price hike, which could further strain AI developers. Analysts on Seeking Alpha and Barchart have also noted the company’s strong position amid the AI boom and its recent valuation adjustments.
