TSMC approves up to $1 billion for Anthropic and OpenAI stakes

Summary

• TSMC's board approved up to $500 million each in Anthropic and OpenAI.
• The chipmaker also posted a 60% jump in October revenue year-over-year.
• The deals pull TSMC's balance sheet into the AI customers it already supplies.

The latest

The world's largest contract chipmaker is buying into the model developers it manufactures for. TSMC said Tuesday its board approved investments of up to $500 million each in Anthropic common shares at the IPO price and in OpenAI preferred stock. The announcement landed alongside a 60% year-over-year rise in October revenue, a figure markets read as evidence that AI demand has not cooled.

Details

• The structure: TSMC's purchases are split between two different instruments: Anthropic common shares bought at the initial public offering price, and OpenAI preferred stock. The company capped each at $500 million, for a combined ceiling of $1 billion.
• Anthropic's offering: Anthropic said Tuesday it will price its IPO at $70 to $78 a share, aiming to raise more than $61 billion at the midpoint of the range. The Claude developer also plans to raise $26 billion from large investors, according to its filing.
• The anchor book: That $26 billion tranche includes Alphabet's Google, Advanced Micro Devices and TSMC itself, the filing showed. TSMC shares rose 4.81%. The investor list places Anthropic's chip supplier, cloud hosts and distribution partners on the shareholder register before the first public trade.
• Analyst reading: Yorkville Ives analysts said the composition of the anchor book "matters more than the headline size," because it binds the companies that sell Anthropic its chips, host its models and distribute its products into the shareholder base ahead of trading.
• The warning: Pictet Wealth Management said in a report that Anthropic's investors and strategic partners include firms that also supply it cloud or infrastructure services, creating what it called critical interdependencies. Analysts cautioned the blurring of investor, supplier and customer roles makes genuine AI demand harder to assess.
• The strategy: The stakes extend TSMC's AI exposure beyond fabricating advanced chips toward direct ownership in the developers driving demand for AI computing infrastructure. TSMC did not set out a timeline for completing either investment.
• Capital spending: The same board meeting approved $40.93 billion in capital expenditure, covering advanced semiconductor manufacturing, advanced packaging, plant construction and research and development investments slated for 2027.
• The backdrop: The approvals came as the AI trade showed signs of strain, giving markets a shot of confidence. TSMC's October revenue growth of 60% from a year earlier was read as a sign that underlying demand remains intact.

Between the lines

TSMC is taking equity in two customers while separately committing $40.93 billion to the capacity those customers will fill. That makes its AI exposure circular: the same demand justifies both the capital spending and the stakes. Pictet's interdependency warning lands directly on this structure, since a supplier holding shares in its buyer has a weaker incentive to read that buyer's demand conservatively.

What's next

Anthropic's IPO pricing within the $70 to $78 range sets the entry cost for TSMC's stake. Watch whether November revenue sustains the 60% growth rate, and how the $40.93 billion capital budget is phased against 2027 research commitments.
