TL;DR
TSMC’s board approved investments of up to $500 million each in Anthropic and OpenAI. Separately, Anthropic’s amended IPO filing says seven companies, including major chip and cloud suppliers, agreed to buy $26 billion of its shares after the listing, while also disclosing large spending commitments to some of those companies. The deals show how supplier funding and AI infrastructure spending are becoming intertwined, but their effect on underlying demand is not yet clear.
TSMC’s board approved up to $500 million investments in Anthropic and OpenAI on November 10, while an amended Anthropic IPO filing disclosed that seven companies have agreed to buy $26 billion of its shares after its listing. The commitments put chipmakers, cloud providers and other AI suppliers among the companies financing a major customer, as well as selling it the infrastructure it needs.
TSMC disclosed the approvals in a filing with the U.S. Securities and Exchange Commission. Its board authorized 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 has already invested the full sums. The filing did not specify a price or date for the OpenAI purchase.
Anthropic’s amended Form S-1, filed the same day, describes a concurrent private placement totaling $26 billion. Google and Nvidia each agreed to purchase about $10 billion of Class N shares; AMD agreed to about $2.5 billion; Broadcom, Micron and Microsoft about $1 billion each; and TSMC Partners, Ltd. about $500 million. The purchases are to occur immediately after the IPO, at its price. The filing says Class N shares have the same economic rights as the public Class A shares but generally carry no voting rights.
The filings also show money flowing back to some of the investors through Anthropic’s infrastructure commitments. According to the company’s filing, it has committed to at least about $121.3 billion with Google and at least $47.2 billion with Microsoft, and expects to spend more than $20 billion on AMD systems. Some share purchases are linked to earlier arrangements: Google’s purchase uses an option in a March 2026 financing agreement, while AMD’s counts toward a $5 billion stock commitment tied to GPU deliveries. These figures describe commitments and expectations in the filing; they do not establish how much has already been paid.
AI suppliers are buying shares in the labs that buy from them
Chip and cloud suppliers are financing leading AI labs while also supplying their infrastructure. The filings show close financial ties, but do not establish how much demand is independent or whether the investments change purchasing decisions.
Who agreed to buy Anthropic shares
The proposed purchases are set to follow the IPO and use its price.
| Company | Approximate commitment |
|---|---|
| $10B | |
| Nvidia | $10B |
| AMD | $2.5B |
| Broadcom, Micron, Microsoft | About $1B each |
| TSMC Partners, Ltd. | About $500M |
Suppliers are also major spending partners
Anthropic’s filing describes large infrastructure commitments to companies among its proposed investors.
At least $121.3B
Anthropic says it has committed this amount to Google.
At least $47.2B
Anthropic says it has committed this amount to Microsoft.
More than $20B
Anthropic expects to spend this amount on AMD systems.
What the filings establish
The documents describe different kinds of commitments, with different levels of certainty.
- TSMC authorized investments of up to $500M each in Anthropic and OpenAI.
- Seven companies agreed to proposed Anthropic share purchases after its IPO.
- Anthropic’s Class N shares generally have no voting rights.
- The final IPO price and completion of the placement.
- Whether TSMC’s full approved amounts will be invested.
- How much committed infrastructure spending will be used or when payments are due.
Why the overlap matters
Supplier funding can support a customer whose infrastructure purchases generate supplier revenue.
Chipmakers and cloud providers commit capital to AI labs.
The filings describe major commitments to chips and cloud capacity.
The documents do not show how much spending reflects independent demand or whether investments change purchases.
Suppliers Become AI Investors
The arrangements make the boundary between AI customer, supplier and investor less distinct. Suppliers may gain a financial stake in a customer whose growth could increase demand for their chips, servers or cloud capacity. At the same time, customer funding can help support the development and infrastructure purchases that generate supplier revenue. The filings document these financial and commercial links, but do not establish that any one investment caused a purchase or that the arrangements are improper.
That overlap matters to companies and investors trying to judge the strength of AI demand. The Wall Street Journal, as cited by Ars Technica, reported analysts’ concern that circular financing can make real demand harder to assess. If a supplier’s investment supports a customer that then spends heavily on the supplier’s products, reported commitments alone may not show how much demand comes from independent customers or how sustainable it is. The disclosed sums are substantial, but the material does not quantify the share of AI infrastructure demand financed this way.
For users and businesses buying AI services, the filings do not directly show a change in access, prices or product quality. They do reveal that a small group of infrastructure companies is closely tied to the capital and capacity plans of leading AI labs. That makes the financial health and spending decisions of those labs relevant beyond the firms themselves.

What the Filings Establish
The two developments come from separate documents. TSMC’s November 10 SEC Form 6-K records board approvals, including the two AI-company investment ceilings and up to $500 million for a new investment company focused on the semiconductor industry and related ecosystem. TSMC has not said whether that vehicle will be used for its Anthropic or OpenAI stakes. The approvals describe permission to invest, not proof that every authorized transaction has closed.
Anthropic’s placement is also distinct from TSMC’s board decision. The filing identifies seven proposed purchasers, their approximate amounts and the shares they would receive after the IPO. It says the placement price will match the IPO price, so the final dollar value per share depends on the eventual offering price. The filing characterizes Class N holders as primarily strategic business partners. The investment therefore does not, by itself, give these suppliers ordinary voting control over Anthropic.
OpenAI’s financing links have their own history. 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 in a quarterly report. Those guarantees are separate from TSMC’s newly approved possible investment. The source material also reports that TSMC approved about $40.93 billion in capital appropriations for new capacity and fabs at the same board meeting, and posted third-quarter net income of NT$763.06 billion. Those figures indicate the scale of its operations, but do not specify how any AI investment will be funded.

Deals Still Await Key Details
Several terms and outcomes remain unsettled. The source material does not give the final IPO price, which determines the per-share cost of Anthropic’s placement, or confirm that the placement has closed. TSMC’s OpenAI approval does not specify a purchase date, price or financing round. Its filing also does not say whether the separate investment company will participate in either deal.
The documents do not quantify how much of the suppliers’ disclosed spending commitments will ultimately be used, when payments are due, or how much AI infrastructure demand depends on this kind of financing. Nor do they establish whether the companies’ investments are changing purchasing decisions. The concern about circular financing is attributed to analysts cited in reporting; it is not a finding in the company filings.
IPO Pricing and Investment Closings
The next key milestones are Anthropic’s IPO pricing and completion of its concurrent placement. Those will determine the final per-share price and whether the seven proposed purchases proceed as described. TSMC’s OpenAI investment may require a later announcement or filing to clarify its timing and terms; the November 10 board resolution alone does not provide them.
Further company disclosures may also clarify how the new investment company relates to TSMC’s stakes and how the firms’ infrastructure commitments are carried out. Until then, the documented approvals, share-purchase agreements and spending commitments should be treated as distinct items, rather than as proof that all funds have changed hands or that the full projected spending will occur.
Key Questions
What did TSMC approve?
TSMC’s board approved up to $500 million for Anthropic shares at its IPO price and up to $500 million for OpenAI preferred stock. The approvals set ceilings; they do not confirm that the full amounts have been invested.
Which companies agreed to buy Anthropic shares?
Anthropic’s filing names Google, Nvidia, AMD, Broadcom, Micron, Microsoft and TSMC Partners, Ltd. It says their purchases total $26 billion and are scheduled for immediately after the IPO, at the IPO price.
Why are these deals described as circular financing?
Some companies investing in Anthropic also supply its chips, systems or cloud infrastructure, and Anthropic’s filing lists large spending commitments to some of them. Analysts cited by The Wall Street Journal have warned that such links can make underlying AI demand harder to judge. The filings do not establish that the financing is improper or quantify its effect on demand.
Have all the announced investments and purchases closed?
The source material does not confirm that all transactions have closed. TSMC’s approvals authorize investments up to set limits, while Anthropic’s filing describes share purchases to take place after its IPO. The final IPO price and the completion of the placement remain key details.
