TSMC Puts Up to $1 Billion Into Anthropic and OpenAI

TSMC's board approved Tuesday an investment of up to $500 million in Anthropic at its IPO price and up to $500 million in OpenAI preferred stock. The commitment, worth up to $1 billion combined, ties the world's largest contract chipmaker directly to the two leading frontier AI labs.

TSMC framed the move as a way to "benefit not only from supplying AI infrastructure, but also from owning stakes in some of the industry's most influential developers." The company is a critical supplier to leading AI firms, including Nvidia. It said demand for AI-related chips remains "extremely robust," even as it adopted a cautious outlook for 2027.

The foundry reported a sixth consecutive quarter of record profit last month. It expects full-year 2026 revenue growth of about 44%, with demand continuing to outstrip manufacturing capacity. It is also spending $265 billion to expand production in Arizona and evaluating further projects in Texas.

What is Anthropic raising and at what price?

Anthropic prices its IPO at $70–$78 per share, targeting a valuation of up to $1.4 trillion. The offering could raise up to $64.4 billion from the market. The company is also raising a separate $26 billion private placement backed by Alphabet's Google, Nvidia, AMD, Microsoft, Broadcom, Micron — and TSMC itself.

Anthropic's prospectus shows run-rate revenue of roughly $81 billion as of October 31, up $10 billion from a month earlier. Third-quarter revenue reached $16.96 billion, a 47% sequential increase, down from 144% growth the prior quarter. The company posted a narrowed net loss in the quarter. It already holds $146.6 billion in liquid assets.

The filing also reveals the cost side. Anthropic carries nearly $900 billion in computing commitments with partners including Amazon and Google. About $69.8 billion of that comes due within 12 months. The IPO proceeds plus the $26 billion private placement would together cover that near-term obligation.

The prospectus carries an unusual risk disclosure. Anthropic warned that its models "have in the past behaved, and may in the future behave, in unintended, misaligned, or autonomous ways, including by taking harmful actions that no user or third party directed." It also flagged the risk that competitors develop models faster and that safety measures may lag capability advances.

Where does OpenAI stand?

OpenAI is seeking to raise $30 billion in what it has called its final private round before a potential IPO early next year. It recently secured $11 billion at a $1.25 trillion valuation, below the $1.5 trillion it initially sought.

OpenAI has not confirmed the TSMC investment amount. A Reuters report cites TSMC's statement that its board approved up to $500 million for preferred stock. OpenAI did not immediately respond to a request for comment.

Why does circular financing worry investors?

Anthropic's cornerstone investors include its own compute suppliers — Google, Nvidia, AMD — and now its chip fabricator, TSMC. Microsoft, also an investor, is both a cloud partner and an OpenAI backer. Investors and analysts have raised concerns about circular financing arrangements, the risk of infrastructure overcapacity, and how quickly AI investments turn into revenue.

Those concerns already move markets. The Nasdaq saw its deepest one-day drop in 19 months on Thursday on fears of increased scrutiny of data-center construction after Democratic gains in the U.S. midterms.

Several questions remain open:

• Whether TSMC's OpenAI investment is contingent on OpenAI's next funding round or IPO timeline.
• The exact terms of the preferred stock, including liquidation preferences, voting rights and conversion triggers.
• How TSMC will account for conflicts between its role as a foundry for multiple AI chip designers and its equity stakes in the model companies that buy those chips.
• Whether other foundries, Samsung and Intel among them, will pursue similar dual roles.

What does the bet signal?

The logic is straightforward. If AI demand keeps growing, TSMC wins as a supplier. If the model layer consolidates around Anthropic and OpenAI, TSMC wins as a shareholder. The $1 billion commitment is small next to its $265 billion U.S. expansion — roughly one part in 265. But it marks a strategic shift from pure-play foundry to a participant in the economics of the models that fill its fabs.
