TSMC's board approved on 10 November two investments of up to $500 million each, one in Anthropic and one in OpenAI, putting a $1 billion ceiling on the combined outlay.
The Anthropic shares would be bought at the IPO price, for which a range of $70 to $78 a share was set. The OpenAI stake would be preferred stock. The filing gives no share count, valuation or closing date.
Anthropic is also raising $26 billion in a private placement, with Google, Nvidia, AMD and Microsoft among the backers. TSMC is the world's largest contract chipmaker and a key supplier to Nvidia, whose chips underpin many AI models.
About TSMC
TSMC, the Taiwan Semiconductor Manufacturing Company, is a Taiwanese contract chipmaker based in Hsinchu Science Park and the world's largest dedicated foundry, supplying customers including Nvidia, Apple, Broadcom and Qualcomm. It was founded in 1987 by Morris Chang as a joint venture of Taiwan's government, the research institute ITRI and private investors, and was the first foundry dedicated to making chips for other companies.
Its US expansion began in 2020, when it announced a $12 billion fab in Phoenix, Arizona; in December 2022 it said it would triple that investment. In April 2024 the US agreed preliminary CHIPS Act funding of up to $6.6 billion for TSMC Arizona, supporting a planned $65 billion-plus in three Phoenix fabs.
Because both figures are caps, the final spend could come in lower. The same meeting approved up to $500 million for a new company to make strategic investments in the semiconductor ecosystem.
