TSMC stock today: Taiwan Semi slips premarket on Nvidia H200 supply talks and a 2nm production update
NEW YORK, December 31, 2025, 05:51 ET — Premarket Taiwan Semiconductor Manufacturing Co’s U.S.-listed shares fell 0.4% in premarket trading on Wednesday after Reuters reported Nvidia was sounding out the chipmaker about expanding production of its H200 artificial intelligence (AI) chips for Chinese customers. Chinese firms have ordered more than 2 million H200 chips for 2026 while Nvidia has about 700,000 units in stock, and it has asked TSMC to start additional output in the second quarter of 2026 using TSMC’s 4-nanometer process, Reuters said, adding that Beijing has yet to greenlight shipments and sources put pricing at around $27,000
