TSMC Q3 Revenue Hits Record High; 31.4% YoY Growth in September Confirms AI Demand Surge

TradingKey - According to results released on October 9, Taiwan Semiconductor Manufacturing Company (TSMC), the world’s leading semiconductor foundry, reported NT$330.98 billion in consolidated revenue for September 2025 — the third-highest monthly figure in its history and the strongest September ever. The result marks a 1.4% decline month-on-month but a robust 31.4% year-over-year increase.

In the first nine months of 2025, TSMC achieved total revenue of NT$2.76 trillion, up 36.4% year-on-year.

Despite the slight MoM dip, September’s performance exceeded TSMC’s own guidance. During its July earnings call, CFO forecasted third-quarter revenue of $31.8–33.0 billion USD, representing an 8% sequential growth and 38% YoY increase. 

Using the midpoint of $32.4 billion USD (approximately NT$984.7 billion) as a benchmark, and considering that July and August revenues totaled over NT$658.9 billion, TSMC needed at least NT$325.8 billion in September to hit target — a threshold it comfortably surpassed.

With this result, TSMC has now posted three consecutive months of revenue above NT$300 billion, bringing its Q3 total to NT$989.917 billion — exceeding the high end of its financial outlook and setting a new record for the best single quarter in company history.

Strong AI-Driven Momentum Confirmed

Analysts noted that TSMC’s Q3 operations once again demonstrated a strong seasonal uptick, with revenue surpassing expectations. Market sentiment remains positive ahead of next week’s earnings call, where TSMC will release its Q3 financial report and provide Q4 and full-year 2026 guidance — developments expected to further support near-term stock performance.

On October 9, TSMC’s Taiwan-listed shares (2330.TW) rose 1.77% to close at NT$1,440, a new closing high, after briefly touching NT$1,455 intraday. Year-to-date, the stock is up over 35%.Meanwhile, TSMC’s U.S.-listed shares (TSM) are up more than 54% in 2025.

AI Tailwinds Fuel Foundry Growth

Recent positive catalysts in the U.S. chip sector have boosted investor confidence:

• Major AI infrastructure deals involving OpenAI, Nvidia, AMD, Oracle, and xAI
• Sustained momentum in the Philadelphia Semiconductor Index (SOX), which continues to hit all-time highs

Nvidia CEO Jensen Huang, in a recent interview, said that demand for Blackwell is truly enormous. They are at the beginning of a whole new industrial revolution.

As the primary manufacturer of Nvidia’s advanced AI chips, TSMC stands as a key beneficiary of this surge.

TSMC President C.C. Wei previously stated that while global economic uncertainty persists, 2025 remains a year of solid growth for the company. He reaffirmed the full-year U.S. dollar-denominated revenue growth forecast of 24–26%, adding they are entering an AI-powered era.
