TSMC approves up to US$1 billion for Anthropic and OpenAI investments

TSMC's board has authorised up to US$500 million to buy Anthropic common shares at its initial public offering price and up to US$500 million for OpenAI preferred stock. The approvals were made at the November 10 board meeting and set spending ceilings, rather than establishing that both investments have already closed.

The same resolutions approved about US$40.93 billion in capital appropriations covering manufacturing capacity, packaging, facilities and other investment requirements. These appropriations were not presented as a new annual capital-expenditure forecast and should not simply be added to an existing yearly budget.

The decisions show a major semiconductor manufacturer extending its proposed financial involvement into two companies that help drive demand for advanced AI chips. They also illustrate the close relationship between model development, financing and the computing infrastructure needed to run AI systems.

Approval does not mean every authorised dollar has been spent, and a board resolution is different from a completed investment transaction. Those distinctions matter when considering the scale of the commitments or their possible effect on the AI supply chain. The board announcement is dated November 10; this report is newly published on November 14.
