TSMC approves up to $500M purchase of Anthropic shares at IPO price

TSMC's board approved the purchase of Anthropic PBC common shares at the per share initial public offering price, in an amount not to exceed $500 million. The approval came in the same November 10 resolutions that covered a matching cap for OpenAI and a separate $500 million strategic investment company.

The release ties the purchase to an offering that has not yet been priced, so the final share count will depend on the IPO terms. Anthropic released Claude Fable 5.2 and Mythos 5.2 the day before, and coverage tied the launch to its planned listing. A foundry taking part in the listing gives the company a large industrial partner on its register before public trading begins.

For founders, an IPO allocation to a chip supplier shows how capital markets and compute planning are merging. Builders watching Anthropic's listing should track how strategic holders shape the float and whether suppliers gain preferred access to capacity.
