TSMC board approves $1 billion investment in Anthropic and OpenAI

Overview

Updated 52 minutes ago

TSMC's board approved up to $500 million for Anthropic common shares at the company's initial public offering price, and up to $500 million for OpenAI preferred stock. The same meeting cleared about $40.9 billion in capital spending and a NT$9.0 per-share quarterly dividend.

TSMC has sold chips to AI firms without owning them. The stakes put the Hsinchu-based manufacturer inside the companies whose model training drives demand for its most advanced processors, and give it a claim on their growth beyond foundry fees.

Why it matters

TSMC now earns from AI twice: as the manufacturer of the chips and as a shareholder in the labs buying them.

Scenarios

TSMC closes its Anthropic stake at the IPO price

Likely Resolves by End of 2026

Discussed by: Reuters and CNA, citing the board approval

Anthropic's shares are expected to begin trading as early as the week of November 16. If the IPO clears at $70 to $78 per share, TSMC's $500 million ceiling buys roughly 6.4 million to 7.1 million shares. The purchase converts a board approval into an owned position.

OpenAI's IPO slips and TSMC's preferred stake waits

Possible Resolves by Q2 2027

Discussed by: Nikkei and Reuters, noting OpenAI has not set a listing date

OpenAI filed confidentially in June but has said no date is fixed. TSMC's $500 million is approved for preferred stock, which can be sold privately before a listing. If the IPO slips past mid-2027, the investment may close as a private placement or not at all.

TSMC builds a standing investment arm

Possible Resolves by End of 2027

Discussed by: Venture Atlas and 工商時報, citing the $500 million investment company approval

The board also approved up to $500 million to set up an investment company for semiconductor and ecosystem deals. If TSMC uses it, the Anthropic and OpenAI stakes become the first positions in a broader portfolio rather than one-off bets.

Historical Context

2 moments from history that rhyme with this story — and how they unfolded.

2012

Chipmakers buy into ASML (2012)

Intel, Samsung and TSMC each bought minority stakes in ASML as part of the Dutch lithography maker's customer co-investment program. The money helped fund extreme ultraviolet lithography, the technology now required for leading-edge chips.

Then

The stakes gave the chipmakers early access to EUV tools and a voice in ASML's development priorities.

Now

ASML became the sole supplier of EUV lithography, and the 2012 arrangement is still cited as a template for supplier-customer equity ties.

Why this matters now

TSMC is again using equity to lock in a relationship with a bottleneck technology, this time on the demand side rather than the supply side.

2019-2023

Microsoft invests in OpenAI (2019-2023)

Microsoft committed billions of dollars to OpenAI across several funding rounds. The deal gave OpenAI access to Microsoft's Azure cloud and gave Microsoft preferential access to OpenAI's models.

Then

OpenAI trained its models on Azure, and Microsoft integrated OpenAI's technology into its products.

Now

The arrangement made Microsoft the dominant cloud partner for a leading AI lab and showed how compute providers could convert infrastructure into equity.

Why this matters now

TSMC is making a smaller version of the same bet: that owning part of an AI lab secures demand for the infrastructure it sells.
