TL;DR
TSMC’s board approved investments of up to $500 million each in Anthropic and OpenAI, while an amended Anthropic filing lists seven companies, including Google and Nvidia, agreeing to buy $26 billion of shares after its IPO. Several investors are also major suppliers or infrastructure providers to Anthropic, raising questions about how much AI demand is supported by this financing cycle.
TSMC’s board approved up to $500 million each for shares in Anthropic and OpenAI on November 10, while Anthropic disclosed that seven companies have agreed to buy $26 billion of its shares immediately after its planned IPO. The disclosures show AI chipmakers, equipment suppliers and cloud providers investing in the companies that buy their products and services, creating financial ties across the AI supply chain.
In a filing with the U.S. Securities and Exchange Commission, Taiwan Semiconductor Manufacturing Co. said its board approved an investment of up to $500 million in Anthropic common shares at the IPO price and up to $500 million in OpenAI preferred stock. Those are ceilings, not commitments to spend the full amounts. TSMC disclosed no price or timetable for the OpenAI purchase. The board also approved up to $500 million to establish an investment company for investments in the semiconductor industry and related ecosystem; the filing does not say whether that vehicle will make either AI company investment.
Anthropic’s amended IPO filing lists an additional, separate transaction: a $26 billion concurrent private placement at the IPO price, planned to close immediately after the IPO. Google and Nvidia each agreed to buy about $10 billion in Class N shares; AMD agreed to about $2.5 billion; Broadcom, Micron and Microsoft to about $1 billion each; and TSMC Partners, Ltd. to about $500 million. The filing says the Class N shares have the same economic rights as the public Class A shares but generally carry no voting rights.
The filing also shows that some investors have significant commercial relationships with Anthropic. It lists spending commitments of at least about $121.3 billion with Google and at least $47.2 billion with Microsoft, and says Anthropic expects to spend more than $20 billion on AMD systems. It identifies Google’s purchase as using an option from a March 2026 financing agreement. AMD’s purchase counts toward a $5 billion stock commitment linked to GPU deliveries. These disclosed figures are not all the same kind of obligation, and the filing does not establish that every projected spend will be completed.
How TSMC, Nvidia and Google Invest Down the AI Supply Chain
AI suppliers are investing in companies that also buy their chips, cloud services and computing capacity. The disclosures reveal connected financial relationships, while leaving actual demand and completed spending uncertain.
Who is buying Anthropic shares?
Seven companies agreed to buy shares in a planned placement immediately after Anthropic’s IPO.
About $10 billion; Anthropic also lists at least about $121.3 billion in spending commitments with Google.
Nvidia
About $10 billion in planned Anthropic shares.
AMD
About $2.5 billion, counted toward a $5 billion stock commitment linked to GPU deliveries.
Other buyers
Broadcom, Micron and Microsoft agreed to about $1 billion each; TSMC Partners to about $500 million.
Capital and commerce overlap
Some investors are also suppliers or infrastructure providers to the companies they fund.
- TSMC approved up to $500 million for Anthropic shares and up to $500 million for OpenAI preferred stock.
- Google and Nvidia each agreed to buy about $10 billion in Anthropic shares.
- Anthropic lists at least about $47.2 billion in spending commitments with Microsoft.
- Anthropic expects to spend more than $20 billion on AMD systems.
What the filings establish
The disclosed figures describe different kinds of arrangements and different stages.
TSMC’s board approved investment ceilings; the full amounts are not confirmed as spent.
Anthropic’s filing describes share purchases planned for after its IPO; closing is not confirmed.
The filings do not show how much projected spending will happen or how much demand depends on supplier financing.
Investors Also Supply AI Capacity
The deals put capital providers and commercial partners on both sides of the AI buildout. Chip and infrastructure companies are backing major customers while those customers commit to buying computing capacity, chips or cloud services. That can help AI companies secure funds and infrastructure at a time when building and operating large-scale models requires substantial computing resources.
The arrangement also makes it harder to assess demand on its own. If a supplier invests in a customer that then spends money on the supplier’s products or services, reported investment and sales may be connected rather than independent measures of market demand. The Wall Street Journal, as cited by Ars Technica, reported analysts’ concerns that this kind of circular financing can complicate judgments about real demand for AI hardware and services. The filings do not establish how much demand depends on these arrangements, or whether the companies’ spending plans will ultimately be met.
For businesses and users, the immediate consequence is not a confirmed change in access, pricing or model performance. The disclosures instead offer a view of how AI companies and their suppliers are financing capacity and sharing exposure to the sector’s growth. The structure may support further investment in computing infrastructure, while also making the financial links between customers and suppliers more important to track.

From Chipmaking to AI Stakes
TSMC manufactures a large share of the chips used in Nvidia’s AI data center products, according to Ars Technica. Its new approvals mark a departure from its usual focus on chip manufacturing: Nikkei Asia, as cited by Taiwan News, reported that TSMC has rarely invested in clients, suppliers or other ecosystem companies. TSMC previously bought shares in chip designer Arm’s 2023 IPO and sold its remaining stake in April 2026, according to Reuters as cited by Taiwan News.
The November 10 board decisions came alongside substantial manufacturing plans. TSMC approved about $40.93 billion in capital appropriations for new capacity and fabs. The company also reported third-quarter net income of NT$763.06 billion, more than $23 billion, according to Reuters as cited by Ars Technica. The earnings figure is historical and does not establish how the new investments will perform.
The OpenAI relationships extend beyond TSMC’s newly approved stake. Ars Technica reported that Nvidia has invested $30 billion in OpenAI so far and disclosed guarantees capped at $105 billion for data center leases used by OpenAI. Those guarantees are a separate exposure from the TSMC investment approval. Together, the reported arrangements illustrate how funding, computing capacity and supplier relationships intersect across the sector.
“Approved the investments in (1) Anthropic, PBC at its per share initial public offering price in an amount not to exceed US$500 million to acquire Anthropic’s common shares; and (2) OpenAI Group PBC in an amount not to exceed US$500 million to acquire OpenAI’s preferred stock.”

Terms and Demand Still Unsettled
TSMC’s approval does not confirm that either investment has closed. The timing and price of its OpenAI purchase remain undisclosed, and the board documents do not specify whether the new investment company will be involved. The Anthropic placement is described in an IPO filing as planned for immediately after the listing, but the available material does not confirm that the IPO or placement has closed.
It is also unclear how much of Anthropic’s stated spending commitments will be realized, how those commitments will be paid over time, or how much AI infrastructure demand is supported by financing from suppliers and partners. The disclosed figures cover different arrangements—share purchases, projected spending and guarantees—and should not be treated as equivalent obligations or as proof of completed transactions.
IPO Closing and Investment Details
The next key event is whether Anthropic completes its IPO and the $26 billion private placement closes at the IPO price, as described in its amended filing. The final share price will determine the dollar value of purchases described using the filing’s midpoint estimate. Further company disclosures may clarify the completed allocations and any changes to the planned transaction.
Investors and customers will also be watching for more information about TSMC’s OpenAI investment, including its timing and price, and whether TSMC uses its newly approved investment company. Future filings or company announcements may provide details. Until then, the disclosed approvals and planned purchases show the commitments and limits stated in the documents, not the final scale of completed investments or the eventual returns.
Key Questions
How much did TSMC approve for Anthropic and OpenAI?
TSMC’s board approved up to $500 million for Anthropic and up to $500 million for OpenAI. These are maximum amounts, not confirmation that the full sums have been invested.
Which companies agreed to buy Anthropic shares?
Anthropic’s amended filing lists Google, Nvidia, AMD, Broadcom, Micron, Microsoft and TSMC Partners, Ltd. as buyers in a planned $26 billion placement after the IPO.
Do the planned Anthropic shares give suppliers voting power?
The filing says the Class N shares generally have no voting rights, except where required by law, while carrying the same economic rights as the public Class A shares.
Why are analysts concerned about these investments?
Analysts cited by The Wall Street Journal and Ars Technica have warned that supplier financing of customers can make it harder to tell how much AI hardware and service demand is independent of those financing arrangements. The disclosures do not quantify that effect.
Have the investments and Anthropic placement closed?
The available documents record TSMC board approvals and Anthropic’s planned placement. They do not confirm that TSMC’s investments or the post-IPO share purchases have closed.
