TSMC has not disclosed additional terms or a timetable. The Anthropic investment is tied to a pending offering. Anthropic has set an IPO range of $70 to $78 per share, seeking a valuation of up to $1.4 trillion, and is separately raising $26 billion in a private placement priced at the IPO price, with backers including Google, Nvidia, AMD and Microsoft. Anthropic was valued at $965 billion in a May 2026 Series H raise. The OpenAI stake is preferred stock in OpenAI Group PBC, and it carries different terms from the Anthropic investment.
TSMC is the world's largest contract chipmaker and a key supplier to Nvidia. Its direct stakes in Anthropic and OpenAI give it exposure to their valuations, not just their chip orders, and both companies are moving toward public markets. Attorneys tracking AI capital deals should watch whether TSMC's Anthropic purchase is executed at the final IPO price, what terms attach to the OpenAI preferred stock, and any follow-up filings. Investor concern about AI spending is growing, and TSMC shares rose more than 4% on Wednesday after its October sales jumped 60% year over year.
