The TSMC Anthropic OpenAI investment is now official. Taiwan Semiconductor Manufacturing said on Tuesday that its board approved up to $500 million in Anthropic shares at the company’s IPO price and up to $500 million in OpenAI preferred stock, putting the world’s biggest chipmaker on both sides of the AI race at once. The move was disclosed in a filing with the U.S. Securities and Exchange Commission, and it arrived alongside a far larger spending plan and a dividend increase for shareholders.
It is a striking position for a company that usually stays in the background. TSMC does not build chatbots or sell AI software. It makes the advanced chips that Anthropic and OpenAI need to train and run their models. Now it will own a piece of both companies as well.
What the TSMC Anthropic OpenAI Investment Covers
The Anthropic half of the deal runs through TSMC Partners, which will buy shares at the IPO price as part of a $26 billion private placement. The OpenAI half is simpler on paper — preferred stock, worth up to $500 million — but TSMC’s filing gives no price and does not say which OpenAI funding round the shares come from. Both investments were approved at the same board meeting on Tuesday, November 10.
Anthropic’s $26 Billion Placement: Google and Nvidia Lead the Way
Anthropic set its IPO price range at $70 to $78 a share on Tuesday, and its amended filing names seven buyers for $26 billion of nonvoting Class N stock. Google is buying about $10 billion worth and Nvidia about $10 billion. AMD is in for about $2.5 billion, while Broadcom, Micron and Microsoft are each buying about $1 billion. TSMC Partners is the smallest of the seven, at about $500 million — 6,756,756 shares at the $74 midpoint of the range.
The placement is scheduled to close right after the IPO, and Anthropic plans to price the offering on November 18, according to CNBC. For the background on the listing itself, see our earlier report on Anthropic’s Nasdaq IPO filing.
OpenAI’s Terms Stay Undisclosed
The OpenAI side of the deal is harder to pin down. TSMC’s filing does not name the funding round or the price it will pay. What is known is that OpenAI has already received about $11 billion at a $1.25 trillion valuation in its current round, according to Bloomberg, and the round could eventually reach $20 billion. Even so, the TSMC Anthropic OpenAI investment gives TSMC a direct stake in both of the leading AI labs. The full filing details were reported by AIStockWire.
A $40.93 Billion Spending Plan and a Bigger Dividend
The same board meeting approved about $40.93 billion in capital appropriations — the money TSMC sets aside for advanced technology and packaging capacity, fab construction and research and development in 2027. It follows $29.44 billion approved in August and $31.28 billion in May, a pace that shows how fast the company is adding capacity for AI chips.
The board also approved up to $500 million to set up a new investment company for strategic investments in the chip industry and related businesses. And shareholders got a raise: the third-quarter cash dividend rises to NT$9.0 a share, up from NT$7.0 for each of the first two quarters of 2026. The ex-dividend date is March 11, 2027, with payment on April 8, 2027 for common shares.
October Revenue Jumped Nearly 60%
The investment news landed alongside strong numbers. In a separate filing on Tuesday, TSMC reported October revenue of about NT$586.89 billion — up 14.7 percent from September and 59.7 percent from October last year. Revenue for the first ten months of 2026 reached NT$4,485.62 billion, up 43.3 percent from the same period in 2025.
Why This Bet Matters
The TSMC Anthropic OpenAI investment is small next to TSMC’s scale — $1 billion combined against tens of billions in annual capital spending. But the signal is large. The company that makes the chips for the AI boom is now a shareholder in two of the labs leading it, at the same time as it pours money into the factories that will supply them. If AI keeps growing at this pace, TSMC wins as a supplier either way; as an investor, it now shares in the upside too. The risk is the same one hanging over the whole sector: if AI spending slows, both the chip orders and the stakes lose value together.
