The Anthropic allocation would buy shares at the company’s initial public offering price, while the OpenAI investment would take preferred stock. Reuters reported the two approvals at a time when TSMC says AI-chip demand remains stronger than available manufacturing capacity.
The transactions are approvals rather than evidence that the full $1 billion has already been invested. TSMC is simultaneously expanding fabrication capacity, including its large Arizona program and potential projects in Texas.
