TL;DR
TSMC’s board approved investments of up to $500 million each in Anthropic and OpenAI, while Anthropic’s amended IPO filing disclosed a separate $26 billion share purchase commitment from seven companies, many of them suppliers or cloud partners. The filings also show large spending commitments flowing from Anthropic back to some investors, raising questions about how much AI demand is independent of supplier financing.
Taiwan Semiconductor Manufacturing Co. approved investments of up to $500 million each in Anthropic and OpenAI, and Anthropic disclosed that seven companies have agreed to buy $26 billion of its shares after its planned IPO. The filings show AI suppliers and infrastructure partners taking stakes in customers whose expansion drives demand for their chips and cloud services.
TSMC disclosed its board decisions in a Form 6-K filed with the U.S. Securities and Exchange Commission on November 10. The board approved up to $500 million to buy Anthropic common shares at the IPO price and up to $500 million for OpenAI preferred stock. The amounts are ceilings, not confirmed final investments. TSMC did not disclose a price or closing date for the OpenAI purchase.
Anthropic’s amended Form S-1, filed the same day, describes a concurrent private placement in which seven companies would buy $26 billion of Class N shares immediately after the IPO, at the IPO price. At the filing’s midpoint estimate, Google and Nvidia would each invest about $10 billion; AMD about $2.5 billion; Broadcom, Micron and Microsoft about $1 billion each; and TSMC Partners, Ltd. about $500 million.
The filing says the Class N shares have the same economic rights as the Class A shares offered to the public but generally have no voting rights. It identifies their holders as primarily strategic business partners. TSMC also approved up to $500 million to establish an investment company for semiconductor-industry and related investments, but has not said whether that vehicle would make either AI-company investment.
AI suppliers take stakes in their customers
AI companies are raising capital from suppliers and infrastructure partners that also expect substantial business from them. The filings show commitments and approvals, not that every deal has closed.
Who may invest in Anthropic
The filing ties the proposed purchases to Anthropic’s planned IPO.
Capital and spending flow both ways
Some proposed investors also have major spending commitments from Anthropic.
- Google and Nvidia: about $10 billion each
- AMD: about $2.5 billion
- Other named companies: about $500 million to $1 billion each
- At least about $121.3 billion with Google
- At least $47.2 billion with Microsoft
- More than $20 billion expected for AMD systems
What the share terms mean
The proposed placement would take place immediately after the IPO at its price.
| Share feature | Class N | Public Class A |
|---|---|---|
| Economic rights | Same | Same |
| Voting rights | Generally none | Not specified here |
What remains unresolved
Approvals and commitments do not confirm completed transactions or cash already paid.
- Anthropic’s placement depends on the planned IPO proceeding.
- TSMC disclosed no price or closing date for its OpenAI purchase.
- TSMC has not said whether its new investment company will participate.
- The filings do not show how much AI demand comes from end users.
When Suppliers Become Investors
The deals connect the financing of AI companies with the companies that sell them essential computing capacity. Anthropic’s filing lists spending commitments to some of its proposed investors that exceed their share purchases: at least about $121.3 billion with Google, at least $47.2 billion with Microsoft, and more than $20 billion expected for AMD systems. Those figures describe commitments and expected spending in the filing, not cash already paid.
That creates a cycle in which suppliers invest in AI companies, and those companies commit substantial sums to suppliers for chips, cloud services or infrastructure. The structure may help labs secure capacity and give suppliers exposure to potential future growth. But it also complicates efforts to judge how much demand reflects customers paying independently for AI products, rather than business relationships supported by investment and spending agreements.
Analysts have raised concerns about this kind of circular financing, The Wall Street Journal reported, as cited by Ars Technica, because it can make underlying demand for AI hardware and services harder to assess. The disclosed commitments do not by themselves establish that demand is artificial or that the arrangements are improper. They do make the money flows relevant to customers, investors and businesses evaluating the AI market.

The Capital Follows Computing Demand
TSMC is the manufacturer of most of Nvidia’s AI data-center chips, according to Ars Technica. Its board’s decisions mark a departure from its usual focus on chip manufacturing: Nikkei Asia has reported that TSMC has rarely invested in clients, suppliers or ecosystem companies. The company bought shares in chip designer Arm’s 2023 IPO and sold its remaining stake in April 2026, according to reporting cited by Taiwan News.
The Anthropic placement is tied to the planned IPO and uses its IPO price. Two of the proposed purchases relate to earlier arrangements: Google’s investment uses an option in a March 2026 financing agreement, while AMD’s purchase counts toward a $5 billion stock commitment linked to AMD GPU deliveries. These details mean the $26 billion is not simply a set of unrelated new investments negotiated at the same time.
OpenAI is also tied to major supplier financing. Ars Technica reported that Nvidia had invested $30 billion in OpenAI and disclosed guarantees capped at $105 billion for data-center leases used by OpenAI. The source material does not provide further terms for those guarantees. Separately, TSMC reported third-quarter net income of NT$763.06 billion and approved about $40.93 billion in capital appropriations for new capacity and fabs, illustrating the scale of its broader investment needs.

Terms and Closing Dates Still Open
The filings do not establish that every proposed investment has closed. Anthropic’s placement is described as occurring immediately after the IPO, but the timing and completion remain tied to that offering. TSMC’s OpenAI approval gives a maximum amount but does not identify the purchase price, transaction date or other terms. TSMC has also not clarified whether its new investment company would be involved.
The documents do not quantify how much of the companies’ overall AI spending is supported by investments, options, guarantees or other arrangements among suppliers and customers. Nor do the disclosed figures alone show what share of future demand comes from end users buying AI services. The commitments vary in type and timing, so they should not be treated as equivalent cash payments already made.
IPO Will Test the Placement
The next major milestone for Anthropic’s disclosed placement is its IPO. If the offering proceeds, the seven companies are expected under the filing’s terms to buy the specified Class N shares at the IPO price immediately afterward. The final amount and closing status should be checked against subsequent filings rather than assumed from the current commitment.
Further disclosures may clarify whether TSMC completes its OpenAI investment, on what terms, and whether its new investment company takes part. Later company filings and financial reports may also provide more detail on the timing of spending commitments and infrastructure arrangements. Until then, the announced approvals and filed commitments establish the structure of the deals, but not their full execution or the amount of AI demand they ultimately support.
Key Questions
What did TSMC approve?
TSMC’s board approved investments of up to $500 million in Anthropic at its IPO price and up to $500 million in OpenAI preferred stock. It also approved up to $500 million to establish an investment company for semiconductor-related investments.
Who agreed to buy Anthropic shares?
The filing names Google, Nvidia, AMD, Broadcom, Micron, Microsoft and TSMC Partners, Ltd. Their proposed purchases total $26 billion at the filing’s stated estimate and are scheduled for immediately after the IPO.
Do the proposed investors get voting rights?
Anthropic’s filing says the Class N shares generally have no voting rights, except where required by law. It says they have the same economic rights as the public Class A shares.
Why are the investments being described as circular financing?
Some suppliers and infrastructure partners are investing in AI companies that also commit to spending large sums on those companies’ products or services. Analysts cited in the source reporting say such arrangements can make underlying demand harder to judge, but the disclosed figures do not prove that demand is artificial.
Have all the investments been completed?
The available filings describe approvals and commitments, not confirmation that every transaction has closed. Anthropic’s placement is tied to its IPO, and TSMC has not disclosed the price or timing of its OpenAI purchase.
