Per WSJ and SEC filings, TSMC's board approved buying Anthropic common shares at its IPO per-share price in an amount not to exceed $500M, plus up to $500M of OpenAI preferred stock.

If confirmed, this implies Anthropic is moving toward an IPO — and TSMC, the core compute supplier to both labs, would take stakes in the two leading frontier AI companies, deepening capital ties between chipmakers and model developers.
