TSMC's board on Tuesday approved investing up to $500 million to acquire Anthropic common shares at Anthropic's per-share initial public offering price, and up to $500 million to acquire preferred stock in OpenAI Group PBC, according to TSMC's board resolutions.

These are board-approved ceilings, described as amounts "not to exceed," not completed purchases. TSMC's release gives no timing, share counts, closing conditions, or other terms. The same meeting approved about $40.9 billion in capital appropriations and up to $500 million to establish a new investment company. Reuters framed the two AI authorizations together as TSMC planning to invest "up to $1 billion" across the two developers.

What TSMC's board actually approved

TSMC's resolutions state that the directors "approved the investments in (1) Anthropic, PBC at its per share initial public offering price in an amount not to exceed US$500 million to acquire Anthropic's common shares; and (2) OpenAI Group PBC in an amount not to exceed US$500 million to acquire OpenAI's preferred stock."

The release, issued from Hsinchu and also furnished in a Form 6-K as reproduced by StockTitan, contains no purchase date, share count, ownership percentage, or other terms for either authorization. It does not describe either approval as a completed transaction or an existing stake.

Two separate AI-lab authorizations

The Anthropic authorization is tied to Anthropic's per-share IPO price, and Anthropic's IPO is not yet priced. Reuters reported that Anthropic set an expected range of $70 to $78 per share on Tuesday and is seeking a valuation of up to $1.4 trillion. Any purchase under TSMC's authorization therefore depends on the IPO going ahead and a final price being set.

The OpenAI authorization is distinct: it is limited to preferred stock in OpenAI Group PBC, with a ceiling of US$500 million. The release does not link it to any specific OpenAI financing round, price, or valuation.

Reuters described the authorizations as highlighting the Taiwanese chipmaker's "confidence in long-term demand" for the technology even as "concerns grow about soaring AI spending," and said the move positions TSMC to benefit not only from supplying AI infrastructure but also from owning stakes. That reading is Reuters'. Reuters also said TSMC last month reported a sixth consecutive quarter of record profit and that demand for AI chips remained "extremely robust."

Capital budget and a new investment company

At the same meeting, the board approved capital appropriations of approximately US$40,926.70 million, or about $40.9 billion. TSMC lists the purposes as mainly including installation and upgrade of advanced technology capacity; installation and upgrade of advanced packaging, mature and/or specialty technology capacity; fab construction and installation of fab facility systems; and 2027 R&D capital investments, sustaining capital expenditures, and capitalized leased assets.

Separately, the board approved "the investment of no more than US$500 million in the establishment of an investment company for the purpose of making strategic investments in the semiconductor industry and related ecosystem." Both items stand apart from the Anthropic and OpenAI authorizations.

What to watch

Whether either authorized purchase proceeds, and on what timetable. The Anthropic item depends on the IPO occurring and on its final per-share price. TSMC has not said whether the OpenAI item relates to any particular financing.

How we reported this

DailyMech read TSMC's Nov. 10 board-resolutions release in full. The same text appears in a Form 6-K as reproduced by StockTitan; the sec.gov page was not opened. Reuters' report was read via the Investing.com reprint; Economic Times and CNA carried the same Reuters story and are not independent confirmation, and the reuters.com original was not opened. Reuters wrote that Anthropic "priced" its IPO; DailyMech did not use that wording, because Anthropic has set only an expected range. DailyMech contacted no one at TSMC, Anthropic, or OpenAI.
