TSM Shares Rise Premarket After Board Approves Anthropic and OpenAI Investments

what happened

The board of Taiwan Semiconductor Manufacturing Co. (TSM) approved on Tuesday investments of up to $500 million in Anthropic common stock bought at the IPO price, plus preferred shares in OpenAI, and announced a higher quarterly payout. Stocktwits reported that U.S.-listed TSM shares gained about 5% in premarket trading on Wednesday, while the Taipei-listed stock finished the session 4.8% higher.

Anthropic set its IPO range at $70 to $78 per share and hopes to raise above $63 billion at the upper end. The Claude developer, whose offering opens next week, is targeting $26 billion from large backers including Alphabet, AMD and TSMC, according to its filing. TSMC's stakes in AI model developers suggest it wants a bigger role in AI infrastructure beyond making chips.

TSMC's filing also lays out a dividend of NT$9.0 (roughly $0.27) for the third quarter, versus NT$7.0 in the second, and capital spending of $40.9 billion for advanced manufacturing, packaging, fab construction and 2027 R&D. A $500 million fund for semiconductor and related companies is also being created. Separately, October sales rose 60% to NT$586.9 billion ($17.9 billion).

why it matters

For investors, the move shows TSMC pushing deeper into the AI supply chain while rewarding shareholders. Shares also drew support from upbeat CoreWeave results and the broader chip-sector reaction to news about Nvidia's CEO. The amounts are modest against TSMC's capital budget, so the main signal is strategic, and the next move will likely depend on the open and sector sentiment.
