TL;DR
TSMC’s board approved investments of up to $500 million each in Anthropic and OpenAI, while Anthropic’s IPO filing disclosed a separate $26 billion share purchase agreement with seven companies, including Google and Nvidia. Several of those investors also supply chips or cloud services to Anthropic, raising questions about how much AI demand is supported by supplier financing.
TSMC’s board approved investments of up to $500 million each in Anthropic and OpenAI on November 10, while Anthropic’s amended IPO filing disclosed a separate agreement for seven companies to buy $26 billion of its shares after its listing. The filings place chipmakers and cloud providers that support AI services among the investors funding the companies buying that capacity.

TSMC disclosed its board decisions in a Form 6-K filed with the U.S. Securities and Exchange Commission. The board approved up to $500 million for Anthropic common shares at the IPO price and up to $500 million for OpenAI preferred stock. These are maximum amounts, not confirmation that TSMC will spend the full sums. The filing specifies the price basis for Anthropic but gives no price, financing round or purchase date for OpenAI.
In a separate resolution, TSMC approved up to $500 million to establish an investment company for strategic investments in the semiconductor industry and related ecosystem. The filing does not say whether that vehicle will hold either AI company stake. TSMC’s approvals are distinct from Anthropic’s placement, which was described in the AI company’s Amendment No. 2 to its Form S-1, also filed November 10.
Anthropic said seven companies had agreed to buy a combined $26 billion of Class N shares immediately after the IPO, at the IPO price. The shares have no voting rights. At the filing’s stated midpoint, Google and Nvidia account for about $10 billion each; AMD is listed at about $2.5 billion; and Broadcom, Micron and Microsoft at about $1 billion each. TSMC Partners, Ltd. is also included. The excerpted source does not give its individual amount.
AI suppliers invest in the labs they serve
Chipmakers and cloud providers are funding AI companies that also buy their capacity. The filings disclose the commitments, but do not show that investment money pays any particular supplier.
Who is funding whom?
The disclosed deals connect AI suppliers with companies buying computing capacity.
Potential stakes in two labs
Its board approved up to $500 million for Anthropic and up to $500 million for OpenAI. These are maximum amounts, not confirmed purchases.
Post-IPO share placement
Google, Nvidia, AMD, Broadcom, Micron, Microsoft and TSMC Partners, Ltd. agreed to buy $26 billion in shares at the IPO price.
The supply chain runs both ways
Some investors also supply chips or cloud services that AI companies use.
- Google and Nvidia each account for about $10 billion of Anthropic’s placement at the filing’s midpoint.
- AMD is listed at about $2.5 billion; Broadcom, Micron and Microsoft at about $1 billion each.
- Nvidia has invested $30 billion in OpenAI, according to the report.
- Anthropic lists at least about $121.3 billion in commitments with Google.
- It lists at least $47.2 billion with Microsoft and expects more than $20 billion for AMD systems.
- These spending commitments have different terms and may cover different time periods.
Why the overlap matters
Supplier investment and customer spending can be linked, which complicates how readers assess demand for AI infrastructure.
Chipmakers and cloud providers fund AI companies.
AI companies purchase chips and cloud infrastructure to develop and run models.
Analysts say the overlap makes underlying demand harder to assess; the filings do not show that demand is artificial.
What remains unconfirmed
The filings describe agreements and approvals, but leave important transaction details open.
- TSMC did not disclose a price or timing for its proposed OpenAI purchase.
- The Anthropic share purchases are tied to the IPO; the supplied information does not confirm the listing or purchases have closed.
- The filings do not trace investment proceeds to specific supplier purchases or quantify how much demand is supported by supplier financing.
When Suppliers Fund Their Customers
The disclosed arrangements bring together companies on both sides of the AI supply chain: some provide chips or cloud infrastructure, while Anthropic and OpenAI buy the computing capacity used to develop and run their models. That means investment and customer spending can be linked. The filings show specific commitments, but do not establish that investment proceeds will be used to pay any particular supplier.
The potential scale of the spending is material. Anthropic’s filing lists commitments of at least about $121.3 billion with Google and at least $47.2 billion with Microsoft, and says more than $20 billion is expected for AMD systems. These figures are spending commitments described in the filing, not the value of the share purchases. The available source does not specify the same time window or detailed terms for each commitment, so they should not be treated as directly comparable totals.
Analysts cited by The Wall Street Journal, as reported by Ars Technica, have warned that this kind of circular financing can make it harder to assess underlying demand for AI hardware and services. The concern is about how to interpret demand when suppliers invest in customers that buy from them; the filings alone do not show that reported demand is artificial or quantify how much is supported by financing.

The Stakes Behind Anthropic’s Filing
Anthropic’s placement is tied to its IPO: the seven companies agreed to buy shares at the IPO price immediately after the listing. The filing’s midpoint estimates describe the expected allocation, while the final purchase price depends on the IPO price. Google’s purchase uses an option from a March 2026 financing agreement, according to the source material. AMD’s purchase counts toward a $5 billion stock commitment linked to its GPU deliveries.
The ties extend to OpenAI. Ars Technica reports that Nvidia has invested $30 billion in OpenAI so far. Nvidia also disclosed in a quarterly report guarantees capped at $105 billion for data center leases used by OpenAI. A guarantee is a financial commitment subject to its terms; it is not the same as a direct cash investment, and the source excerpt does not detail how much has been drawn or what conditions apply.
TSMC has generally focused on semiconductor manufacturing rather than investing in companies across its supply chain, according to Nikkei Asia, as cited by Taiwan News. It bought shares in chip designer Arm’s 2023 IPO and sold its remaining stake in April 2026, Taiwan News reported, citing Reuters. TSMC’s latest approvals therefore mark a notable step, though the company has not explained how it will structure or manage the proposed investments.

Open Questions on Price and Demand
TSMC’s proposed OpenAI purchase has no disclosed price or timing in the board resolution. The filing also does not say whether the new investment company will be involved in either AI stake. For Anthropic, the $26 billion placement is described as an agreement tied to the IPO, but the source material does not establish that the listing or purchases have closed.
The available details also leave the ultimate flow of funds unclear. The filings identify investments and spending commitments, but do not trace investment proceeds to specific chip, equipment or cloud purchases. Nor do the supplied sources quantify what share of AI infrastructure demand is funded directly or indirectly by suppliers. The reported commitment totals have different stated terms and may not cover identical periods.
The IPO Will Set the Purchase Price
Anthropic’s share placement is scheduled to occur immediately after its IPO, with purchases priced at the eventual IPO price. The filing excerpt does not provide a listing date or final share price. Investors and customers will be able to compare the disclosed commitments with later filings and company statements as the offering progresses.
TSMC’s Form 6-K records the board approvals, but does not provide a timetable for completing the OpenAI investment or explain how the investment company will operate. Further company disclosures would be needed to confirm the amounts invested, the transaction terms and any link between the stakes and future supplier contracts.
Key Questions
How much did TSMC approve for Anthropic and OpenAI?
TSMC’s board approved up to $500 million for each company. The Anthropic shares are priced at the IPO price; the OpenAI resolution does not state a price or date.
Which companies agreed to buy Anthropic shares?
The filing names Google, Nvidia, AMD, Broadcom, Micron, Microsoft and TSMC Partners, Ltd. Together, they agreed to buy $26 billion of Class N shares after the IPO, at the IPO price.
Does the $26 billion placement mean the IPO has closed?
No. The filing describes an agreed purchase after the IPO. The supplied information does not confirm that the listing or the share purchases have closed.
Why are analysts concerned about supplier investments?
Analysts cited by The Wall Street Journal and Ars Technica say supplier financing can make it harder to judge underlying demand when AI companies buy chips and cloud capacity from companies that also invest in them. The cited concern does not establish that demand is overstated.
