Taiwan Semiconductor Manufacturing Co., the world's largest contract chipmaker, approved board-level investments of as much as $1 billion to buy stakes in two of the world's biggest artificial intelligence developers, a filing with the U.S. Securities and Exchange Commission shows.
The filing, dated November 10 and signed by Senior Vice President and Chief Financial Officer Wendell Huang, says TSMC will spend up to $500 million on common shares of Anthropic at its initial public offering price and up to $500 million on preferred stock of OpenAI.
Anthropic has set an IPO price range of $70 to $78 a share, valuing the company at up to $1.4 trillion, and separately raised $26 billion in a private placement from Google, Nvidia, AMD and Microsoft.
TSMC described the deal only as “strategic investments in the semiconductor industry and related ecosystem,” without elaborating. The company remains a major supplier to Nvidia and other AI chip designers; buying into Anthropic and OpenAI makes it a shareholder in two of the customers driving that demand.
TSMC expects revenue to grow 44% in 2026 and has budgeted $265 billion in capital spending, while striking a cautious tone on 2027.
The filing does not disclose what stake TSMC will end up holding in either company or when the deals will close. TSMC shares trade on the Taiwan Stock Exchange under ticker 2330 and on the New York Stock Exchange under ticker TSM.
