TSMC’s board authorized investments of up to $500 million each in Anthropic and OpenAI on November 10, giving the semiconductor manufacturer a potential ownership stake in two major AI developers. The decision places the company on both sides of the AI buildout: producing chips for the industry while committing capital to model developers.
According to TSMC’s published board resolutions, the Anthropic investment would buy common shares at the company’s initial public offering price. The OpenAI investment would buy preferred stock. These are approved spending ceilings, not a statement that the transactions have already closed or that the full amounts have been paid.
Two investments with different terms
The distinction between common and preferred shares matters. They are different classes of ownership and can carry different rights. TSMC’s brief announcement does not detail the OpenAI security’s preferences, a valuation for that investment or a closing timetable.
The Anthropic commitment is tied to an IPO price, rather than a fixed share count in TSMC’s announcement. The eventual number of shares therefore depends on the final transaction terms. Investors should distinguish an authorization from a completed purchase when comparing the headline total with cash actually deployed.
Reuters, in a report carried by CNA, placed the decision within a broader network of links between AI developers and infrastructure suppliers. It noted TSMC’s role as a critical chip supplier, including for Nvidia, and the wider investment backing around Anthropic’s offering.
Manufacturing spending remains central
The same board meeting approved approximately $40.93 billion in capital appropriations covering technology capacity, packaging, factory work and other planned investments. It separately authorized up to $500 million to establish an investment company focused on the semiconductor industry and related businesses, according to TSMC.
These separate resolutions should not be combined into an assertion that all the money is being invested in AI developers. Factory appropriations, an investment-company allocation and direct share purchases have different purposes. Nor does a board appropriation, by itself, establish when each dollar will be spent.
Reuters reported that TSMC had described AI-related chip demand as strong in its preceding earnings update while taking a cautious approach to the following year. That provides business context for the decision, but it is not a guarantee of returns from the proposed stakes.
Revenue data show the scale of growth
In a separate October revenue release published November 10, TSMC reported consolidated sales of about NT$586.89 billion. That was 14.7% above September and 59.7% higher than a year earlier. Revenue for the first ten months reached approximately NT$4.49 trillion, up 43.3% from the comparable period.
Those figures measure the company’s total sales, not revenue attributable to the two proposed investments or to AI alone. They show the expanding scale of its existing manufacturing business, while the ownership stakes introduce a different form of exposure. Further disclosures on completed purchases and their terms will be needed to establish the final size and structure of that exposure.
