TSMC’s board approved investments of up to US$500 million each in OpenAI and Anthropic on 10 November 2026, creating a combined ceiling of US$1 billion. The board resolutions authorise purchases; they do not confirm that either investment has been completed.
What TSMC’s board approved
The two AI-company investments sit in resolution five. Resolution four separately approves funding to establish an investment company. The distinction prevents the latter amount from being counted as additional money committed to the two developers.
