TL;DR
TSMC’s board approved investments of up to $500 million each in Anthropic and OpenAI. Separately, seven companies that supply chips or cloud capacity agreed to buy a combined $26 billion of Anthropic shares after its IPO, while Anthropic disclosed much larger spending commitments to several of those investors.
TSMC’s board approved investments of up to $500 million in Anthropic and up to $500 million in OpenAI on November 10, while Anthropic disclosed that seven companies, including Google and Nvidia, had agreed to buy $26 billion of its shares after its planned IPO. The filings show how chipmakers and cloud providers are investing in AI companies that, in turn, expect to spend heavily on their hardware and services.

TSMC disclosed the approvals in a Form 6-K filed with the U.S. Securities and Exchange Commission. The Anthropic investment would buy common shares at the IPO price; the OpenAI investment would buy preferred stock. Both amounts are ceilings, not fixed checks. TSMC did not disclose a price or timing for the OpenAI purchase. Its board also approved up to $500 million for a new investment company focused on the semiconductor industry and related ecosystem. The filing does not say whether that vehicle will make either AI investment.
Anthropic’s amended IPO filing describes a concurrent private placement in which Google, Nvidia, AMD, Broadcom, Micron, Microsoft and TSMC Partners, Ltd. agreed to buy a total of $26 billion in Class N shares at the IPO price, immediately after the listing. The shares have no voting rights. At the midpoint of the proposed price range, Google and Nvidia would each invest about $10 billion; AMD about $2.5 billion; and Broadcom, Micron and Microsoft about $1 billion apiece. The supplied filing summary does not specify TSMC Partners’ individual amount.
The filing also lists large spending commitments to some investors. Anthropic’s commitments include at least about $121.3 billion with Google, at least $47.2 billion with Microsoft, and more than $20 billion expected for AMD systems. Google’s share purchase uses an option from a March 2026 financing agreement. AMD’s purchase counts toward a previously announced $5 billion stock commitment linked to its GPU deliveries.
Inside the AI deals linking suppliers and customers
Chipmakers and cloud providers are investing in AI companies that expect to spend heavily on their hardware and services. The filings show commitments, but not how much demand will ultimately come from end customers.
Who is buying Anthropic shares?
Seven companies agreed to buy Class N shares after Anthropic’s planned IPO.
Investment meets expected spending
AI providers gain capital while suppliers may gain business from their customers’ infrastructure needs.
- TSMC approved up to $500 million each for Anthropic and OpenAI.
- Google and Nvidia would each invest about $10 billion in Anthropic at the IPO price midpoint.
- Anthropic lists at least about $121.3 billion with Google.
- It lists at least $47.2 billion with Microsoft and more than $20 billion expected for AMD systems.
Why the links matter
The same businesses can fund AI companies and supply the computing capacity those companies expect to use.
Investments can help fund expansion and secure computing capacity.
Chipmakers, equipment providers and cloud companies support AI models.
The filings do not show how much demand is independently funded or how profitable these arrangements will be.
What remains unresolved
Approved ceilings and planned terms do not confirm final transactions.
- TSMC has not disclosed the price or timing of its OpenAI purchase.
- Anthropic’s placement is planned for immediately after its IPO; whether it closes as planned remains uncertain.
- The supplied information does not specify TSMC Partners’ individual commitment.
- The disclosed commitments do not establish future service prices, availability or competition.
When AI Suppliers Fund Their Buyers
The arrangements connect investment in AI companies with revenue expected by the businesses supplying their computing capacity. That can support rapid expansion: AI labs can raise capital from companies able to provide chips, equipment or cloud infrastructure, while suppliers gain exposure to customers whose future spending may be substantial.
It also makes the economics harder to read. The Wall Street Journal, as cited by Ars Technica, reported analysts’ concerns that this kind of circular financing can obscure how much demand for AI hardware and services is independently funded. The filings document proposed investments and spending commitments; they do not establish how much demand is ultimately driven by end customers or how profitable the arrangements will be.
For businesses and users, the immediate development is a financing structure that may help AI providers secure capacity and capital. The disclosed figures alone do not establish what it will mean for service prices, availability or long-term competition.

TSMC’s Move Beyond Chipmaking
TSMC is a major manufacturer of Nvidia’s AI data center chips, according to Ars Technica. Its newly approved stakes represent an unusual step for a company that has generally focused on manufacturing rather than investing in clients or ecosystem businesses, Nikkei Asia reported. TSMC bought shares in chip designer Arm’s 2023 IPO and sold its remaining stake in April 2026, according to Reuters reporting cited by Taiwan News.
The Anthropic and OpenAI decisions were made as TSMC also approved about $40.93 billion in capital appropriations for new capacity and fabs. It reported third-quarter net income of NT$763.06 billion, more than $23 billion, according to Reuters reporting cited by Ars Technica. Those figures give context to the scale of TSMC’s investment capacity, but do not indicate how much it will ultimately spend on either AI company.
Anthropic’s placement includes both fresh commitments and arrangements tied to earlier agreements. Google’s purchase exercises an option from a March 2026 financing agreement; AMD’s purchase is counted toward a $5 billion commitment associated with its GPU deliveries. On the OpenAI side, Ars Technica reported that Nvidia had invested $30 billion so far. Nvidia also disclosed guarantees capped at $105 billion for data center leases used by OpenAI in a quarterly report.

Terms Still Awaiting Disclosure
TSMC has not disclosed the price, timing or specific transaction through which it would buy OpenAI preferred stock. The company also has not said whether its newly approved investment vehicle would hold either AI stake. The filings set maximum amounts for TSMC’s purchases, so the final investment could be lower.
Anthropic’s $26 billion placement is described as taking place immediately after its IPO, but whether it closes as planned remains uncertain. The supplied information does not give TSMC Partners’ individual commitment. The disclosed spending commitments also do not establish when or how much Anthropic will pay, or what share of future AI demand will be supported by investments from suppliers and cloud providers.
IPO Closing and Investment Terms
The next major milestone is Anthropic’s IPO and the planned private placement immediately after the listing. The final IPO price will determine the price paid for the Class N shares under the terms described in the filing. The closing will show whether the seven-company placement proceeds as planned and clarify the resulting share purchases.
Further disclosures may provide details on TSMC’s OpenAI investment, including its timing and price. Until then, the November 10 filings establish approved ceilings and agreed placement terms, while leaving the final amounts and broader scale of supplier-funded AI demand unresolved.
Key Questions
How much did TSMC approve for Anthropic and OpenAI?
TSMC approved up to $500 million for each company, for a combined maximum of $1 billion. The approvals are ceilings, not confirmation that the full amounts will be invested.
Which companies agreed to buy Anthropic shares?
Google, Nvidia, AMD, Broadcom, Micron, Microsoft and TSMC Partners, Ltd. agreed to buy a combined $26 billion in Class N shares after Anthropic’s planned IPO.
Why are the investments described as circular financing?
Several investors also supply chips, equipment or cloud infrastructure that AI companies use and expect to spend on. Analysts cited by the Wall Street Journal have warned that this overlap can make independent demand for AI services and hardware harder to assess.
Is Anthropic’s $26 billion placement complete?
No. The filing describes an agreement to buy shares immediately after the IPO. Whether the placement closes as planned remains to be seen.
