Moody's Ratings revised its outlook on Taiwan Semiconductor Manufacturing Company (TSMC) to positive from stable, while affirming its Aa3 issuer rating on August 28, 2026. The upgrade reflects TSMC's dominant market position, technological leadership in semiconductor manufacturing, and strong growth prospects fueled by high demand for artificial intelligence (AI) applications. Moody's anticipates TSMC's revenue will grow 30%-40% annually over the next 12-18 months.
This announcement came as TSMC's stock (2330.TW) rose NT$10 to close at NT$2,420 amid a broader rally in the Taiwanese stock market. The market's positive momentum was largely driven by better-than-expected earnings from Nvidia, a key TSMC customer, which boosted investor confidence across the AI supply chain. On the same day, a report from Counterpoint Research highlighted TSMC's commanding 73% share of the global pure-play foundry market in the second quarter.
