TSMC board approves up to $1 billion in Anthropic and OpenAI investments

TSMC’s board approved investments of up to $500 million apiece in Anthropic and OpenAI. The authorizations set a combined ceiling of $1 billion, but the company did not say either share purchase had closed.

Under its Nov. 10 board resolution, TSMC may acquire Anthropic common shares at the company’s per-share initial public offering price and OpenAI preferred stock. The resolution does not say how much TSMC could ultimately invest below either cap or when the transactions might close.

The Anthropic authorization ties the purchase price to the IPO but gives neither its timing nor per-share price. The OpenAI authorization identifies the security as preferred stock without disclosing additional terms.

In a separate action, the board approved up to $500 million to establish an investment company focused on strategic investments in the semiconductor industry and related ecosystem. That authorization sits outside the combined $1 billion cap for Anthropic and OpenAI.
