TSMC Board Approves Up to $1 Billion in Anthropic and OpenAI Stakes as the Chipmaker Buys Into Its Biggest AI Customers

Taiwan Semiconductor Manufacturing Company, the world’s largest contract chipmaker, has decided to buy into the companies that buy its chips. At a board meeting in Hsinchu on Tuesday, November 10, 2026, TSMC’s directors approved investments of up to $500 million each in Anthropic and OpenAI, the two artificial intelligence developers whose models are driving the largest build-out of computing hardware in history, for a combined ceiling of up to $1 billion. The same meeting approved a capital budget of about $40.93 billion, raised the quarterly dividend to a record, and authorised up to $500 million more to set up a semiconductor investment company, in a single session that shows how completely the AI boom now shapes the world’s most important chip factory. The two AI investments are structured differently: the Anthropic money would buy ordinary shares at the price of the company’s initial public offering, which opened its roadshow on the same day, while the OpenAI money would buy preferred stock in a private company that has filed confidentially for its own listing but has set no terms. The board’s resolutions, filed with the United States Securities and Exchange Commission, are approvals to spend, not completed purchases: they name no share counts, no ownership percentages and no closing dates, and the company has stressed that the actual amounts invested, the eventual shareholdings and the completion dates are yet to be disclosed. Even so, the decision is a striking one, because it turns the supplier at the base of the AI supply chain into a shareholder in two of its most important customers, at the very moment those customers are racing to secure the chips they need. This report sets out what TSMC’s board approved, what the two investments would look like, why the chipmaker is making them, and what is still unconfirmed, drawing only on the company’s own board resolutions and the reporting of them. The TSMC $1 billion Anthropic OpenAI November 2026 decision is the focus of this report.

1. What TSMC’s Board Actually Approved

The board meeting took place on Tuesday, November 10, 2026, at TSMC’s headquarters in Hsinchu, Taiwan, and the resolutions were disclosed the same day in a filing with the United States Securities and Exchange Commission, a Form 6-K, which is the document foreign companies use to report material events to American regulators. The filing is the primary source for everything that follows about the approvals, and it is worth reading carefully, because the numbers it contains are ceilings rather than cheques. The board approved two separate AI investments, each capped at $500 million, and it approved them as subscriptions: a subscription for ordinary shares in Anthropic, priced at the company’s initial public offering price, and a subscription for preferred shares in OpenAI. Together they add up to a maximum of $1 billion, and that combined ceiling is the figure that has travelled furthest in the coverage, but the two halves of it are not the same kind of transaction, and the differences between them matter. The board also approved a third investment resolution in the same session, up to $500 million to establish an investment company that would make strategic investments in the semiconductor industry and the related ecosystem, which takes the ceiling for the strategic moves approved that day to $1.5 billion, although that third item is a separate authorisation and should not be confused with the $1 billion combined ceiling for the Anthropic and OpenAI investments. Alongside the investment resolutions, the board approved the capital budget, the third-quarter business report and financial statements, and the record dividend. The meeting, in other words, was a full quarterly board session, and the AI investments were one item on a long agenda, but they are the item that has drawn the most attention, because they mark a change in what TSMC is willing to be.

1.1 The Anthropic Leg: $500 Million at the IPO Price

The Anthropic half of the approval is the more concrete of the two, because it is tied to a public event with a published price range. TSMC’s board authorised a subscription of up to $500 million in ordinary shares of Anthropic, PBC, with the price to be set by the company’s initial public offering. Anthropic opened its IPO roadshow on November 10, the same day as TSMC’s board meeting, offering shares at $70 to $78, and pricing is expected on November 18, with trading to begin on the Nasdaq under the ticker ANT. That means the size of TSMC’s eventual stake stays open until the offering is priced: at the top of the range, $500 million would buy fewer shares than at the bottom, and until the price is set, the only fixed number in the resolution is the $500 million ceiling. Anthropic is reported to be seeking to raise up to $90.4 billion through its IPO and a private placement at a valuation of about $1.4 trillion, which would make the debut one of the largest listings ever recorded, and TSMC is reported to be among the private-placement participants. The structure is notable for another reason: buying at the IPO price puts TSMC in the same position as any other investor in the offering, paying the price the market sets, rather than negotiating a private valuation of its own. That is a straightforward way for a strategic investor to take a stake, and it is the route TSMC has chosen for the Anthropic leg.

1.2 The OpenAI Leg: $500 Million in Preferred Stock

The OpenAI half of the approval is a different kind of transaction, and it is the one with more blanks in it. TSMC’s board authorised a subscription of up to $500 million for preferred stock in OpenAI Group PBC, and the resolution says nothing about a price, a valuation, a timetable or an eventual ownership percentage. There is no IPO to price against, because OpenAI is not listed, and the company has filed confidentially for its own listing but has not set terms, so the OpenAI leg is a private deal whose economics are not yet public. Preferred stock, in the usual sense, is a class of shares that typically carries priority over ordinary shares in a payout, and often comes with negotiated rights, but the resolution does not say what rights, if any, TSMC’s preferred shares would carry, and no reporting of the announcement has filled in those details. What is clear is that the two legs are not symmetrical: one is a public-market purchase at a market price, and the other is a private subscription whose terms are still to be agreed. The board’s approval gives TSMC permission to spend up to $500 million on each, and whether the full amounts are deployed, and when, is still to be disclosed.

2. The $40.9 Billion Capital Budget Behind the Headline

The AI stakes are the most eye-catching item from the board meeting, but they are not the largest. The same session approved a capital budget of about $40.93 billion, or about NT$1.345 trillion, which is the money TSMC plans to spend on its factories, its equipment and its technology over the coming period. That figure is more than forty times the combined ceiling for the two AI investments, and it is a useful reminder of scale: TSMC is, first and foremost, a manufacturer, and the AI stakes are a side bet on its customers, not a change of business. The capital budget is the spending that keeps the company at the front of the industry, funding the advanced manufacturing processes and the packaging technologies that the AI developers need for their most powerful chips. It was approved alongside the third-quarter business report and financial statements, which the board also signed off on, and it sits in the same filing as the AI resolutions, which is why the two stories have travelled together in the coverage.

2.1 Where the Money Goes: Advanced Nodes and Packaging

A capital budget of $40.93 billion is spent on the things that make TSMC’s factories work: the advanced manufacturing nodes, the process technology that shrinks transistors and packs more of them onto each chip, and the advanced packaging that joins chips together into the powerful modules that AI systems require. The reporting of the board meeting describes the budget as funding advanced nodes and packaging, which are the two areas where TSMC’s lead over its rivals is widest, and where the demand from AI customers is most intense. The AI models built by Anthropic and OpenAI run on accelerators that depend on TSMC’s most advanced processes, and those accelerators are assembled using the packaging techniques that TSMC has spent years developing. The capital budget, then, is the other side of the same story as the AI investments: the company is spending tens of billions to build the capacity its AI customers need, and it is now also spending up to a billion to own a small piece of those customers themselves. The two decisions reinforce each other, and they both point in the same direction, which is that TSMC expects the demand for AI computing to keep growing, and it is prepared to spend at a scale that matches that expectation.

2.2 A Record Dividend Alongside the Spending

The board also raised the third-quarter cash dividend to NT$9 per share, a quarterly record, which is a signal of a different kind. A company that is spending $40.93 billion on capital and approving up to $1.5 billion in strategic investments could reasonably be expected to hold its dividend steady, but TSMC chose to raise it, and the raise tells shareholders that the board believes the company can fund its expansion and still return more cash. The dividend timetable was also disclosed: the common shares go ex-dividend on March 11, 2027, with a record date of March 17 and payment on April 8. The third-quarter results that the board approved alongside the dividend give some context for that confidence. TSMC reported third-quarter revenue of NT$1,494.24 billion and net income of NT$763.06 billion, which are figures that put the scale of the company in perspective: the $1 billion combined ceiling for the AI investments is less than a single quarter’s profit, and the $40.93 billion capital budget is roughly a quarter’s revenue. That is not to say the money is small, but it is to say that TSMC is making these decisions from a position of considerable financial strength, and that the dividend increase is the board’s way of saying so.

3. Why the World’s Biggest Chipmaker Wants a Stake in Its Customers

TSMC is the world’s largest dedicated contract chipmaker, which means it makes chips designed by other companies and does not sell its own branded processors. That model has made it the indispensable manufacturer at the centre of the global semiconductor industry, and it has also made it unusually dependent on the health of its customers: when the companies that design chips are doing well, TSMC’s factories are full, and when they struggle, the orders slow down. The board’s decision to take stakes in Anthropic and OpenAI is a departure from that model, because it turns a pure supplier into a part-owner of two of the companies that drive its demand. It is worth asking why a manufacturer with full order books and record profits would want to do that, and the answer lies in the structure of the AI boom itself. The demand for AI computing is not like the demand for smartphones or laptops, where many customers each buy a little; it is concentrated in a small number of very large developers, and the two largest of them, by most measures, are OpenAI and Anthropic. Owning a stake in those two companies is, in effect, a way of owning a piece of the demand itself.

3.1 From Supplier to Shareholder

The simplest way to understand the move is as a change of position. A supplier sells a product and takes the money; a shareholder owns a piece of the customer and shares in what the customer becomes. TSMC has always been a supplier, and a very successful one, but the AI boom has changed the balance of power in the industry, because the customers that matter most are now so large, and their demand is so concentrated, that the supplier’s fortunes are tied to theirs in a way they were not before. Taking a stake in Anthropic and OpenAI is a way of formalising that link, and of sharing in the upside if those companies grow as fast as their valuations suggest they might. It is also a way of deepening a commercial relationship: a supplier that is also a shareholder has a reason to keep the customer close, and a customer that counts its supplier among its shareholders has a reason to keep ordering. The amounts involved are small relative to TSMC’s scale, which suggests the stakes are strategic rather than financial in the ordinary sense: $500 million will not change TSMC’s balance sheet, but a seat at the table of two of the world’s most important AI companies might change its relationships. The coverage of the announcement has described the move in exactly those terms, as the company that makes AI chips now wanting to own a piece of the AI companies, and that description captures the shift.

3.2 The Demand Signal TSMC Sees First

There is a second reason the move makes sense, and it has to do with information. TSMC sees the demand for AI computing before almost anyone else, because it sees the orders. When a developer like Anthropic or OpenAI wants more computing power, it orders more chips, and those orders arrive at TSMC’s factories months before the new models are announced or the new data centres are switched on. That gives TSMC an unusually clear view of where the AI industry is heading, and the board’s decision can be read as a vote of confidence based on that view. If the company that makes the chips for the AI boom is willing to put its own money into the companies driving it, that is a signal about what the order books are saying, even if the company itself has not said it in so many words. It is also a signal that runs in the other direction: the AI developers have been racing to secure supply, signing long-term agreements and in some cases investing in their own chip designs, and a supplier taking a stake in its customers is a sign that the relationship is becoming more entangled, not less. The AI supply chain, which used to be a chain of separate companies each doing one thing, is becoming a web of cross-holdings and partnerships, and TSMC’s decision is one more strand in that web.

4. Anthropic’s IPO: The Numbers Behind the $500 Million

The Anthropic leg of the approval cannot be understood without the IPO it is tied to, because the price TSMC will pay, and the size of the stake it will end up with, are both determined by that offering. Anthropic opened its IPO roadshow on November 10, the same day as TSMC’s board meeting, offering shares at $70 to $78, and the offering is expected to price on November 18, with trading to begin on the Nasdaq under the ticker ANT. The company is reported to be seeking to raise up to $90.4 billion through its IPO and a private placement at a valuation of about $1.4 trillion, which would make the debut one of the largest listings ever recorded. Those numbers are large by any standard, and they are the reason the TSMC stake, which is small in absolute terms, is still newsworthy: it is a bet on a company that the market is valuing at more than a trillion dollars before it has even started trading.

4.1 A $70 to $78 Range and a $1.4 Trillion Valuation

The price range of $70 to $78 a share is the starting point for the offering, and it is the number that will determine what TSMC’s $500 million buys. At the top of the range, $500 million buys fewer shares than at the bottom, and the final price will be set on November 18, when the offering is expected to price, so until then the size of TSMC’s stake is unknown. The valuation of about $1.4 trillion that has been reported for the company is a striking figure, and it is worth pausing on what it means: it would make Anthropic, a company that builds the Claude family of AI models, one of the most valuable companies in the world on its first day as a public company. That valuation is not yet final, and it depends on the price the market is willing to pay, but the fact that it is being discussed at all shows how far the AI industry has come, and how much investors are willing to pay for a share of it. The offering is also reported to be drawing strong demand, with coverage describing it as oversubscribed, which means that more investors want shares than are available, and that the price could settle at or above the top of the range. For TSMC, that is both good news and bad news: good, because a strong offering validates the investment, and bad, because a higher price means fewer shares for the same $500 million.

4.2 The $26 Billion Private Placement Around the Listing

Alongside the IPO itself, Anthropic is reported to be assembling a private placement of $26 billion, with Alphabet’s Google, Nvidia, AMD and Microsoft among the investors participating, and TSMC reported to be among the private-placement participants as well. A private placement is a sale of shares to a small group of large investors, outside the public offering, and it is a common feature of very large listings, because it lets the company raise more money than the public market alone can absorb, and it lets strategic investors take a stake without competing in the open market. The list of reported participants is itself a map of the AI industry: Google, which builds its own AI models and its own chips; Nvidia, which designs the accelerators that power AI; AMD, Nvidia’s main rival in that market; and Microsoft, which is OpenAI’s largest backer. TSMC’s presence on that list, alongside those names, is a sign of how central the chipmaker has become to the industry, and of how intertwined the major players now are. It is also worth noting that the private placement and the IPO are separate transactions, and that TSMC’s board resolution, which speaks of a subscription at the IPO price, is a different item from the private placement, even if the two are connected. The reporting has not always kept that distinction clear, and it is worth keeping it in mind.

5. OpenAI’s Side: Preferred Stock, No Price, No Timetable

If the Anthropic leg is defined by a public price range and a timetable, the OpenAI leg is defined by the absence of both. OpenAI is a private company, and the board’s resolution authorises up to $500 million for preferred stock in OpenAI Group PBC, with no price, no valuation, no closing date and no ownership percentage disclosed. That is not unusual for a private investment, where the terms are negotiated between the parties and disclosed only when the deal closes, but it does mean that the OpenAI half of the story is, for now, a permission to spend rather than a transaction with visible terms. The company has filed confidentially for its own initial public offering, according to the reporting, but it has not set terms, and its IPO details remain thin, so there is no public benchmark against which to measure the $500 million.

5.1 What Preferred Stock Means Here

Preferred stock is a class of shares that usually carries priority over ordinary shares when a company pays dividends or is sold, and it often comes with negotiated rights, such as a say in certain decisions or protection against a fall in value. The board’s resolution does not say what rights TSMC’s preferred shares would carry, and no reporting of the announcement has filled in those details, so it is not possible to say, from the public record, what exactly TSMC would be buying. What can be said is that preferred stock is the instrument of choice for a strategic investor in a private company, because it lets the investor put money in without taking the ordinary shares that the company’s founders and employees hold, and it lets the terms be tailored to the relationship. For TSMC, which is buying into a company that is also one of its most important customers, that tailoring matters: the terms of the preferred stock will determine not just the financial return, but the nature of the relationship, and those terms have not been disclosed. The resolution authorises the spending, and the negotiation of the terms is presumably still to come, or has taken place privately and has not been made public.

5.2 A Confidential Filing and an Unpriced Future

OpenAI’s own path to the public markets is further behind Anthropic’s, and that gap is part of the story. The company has filed confidentially for an initial public offering, which means it has submitted its paperwork to regulators without making it public, a step that companies take when they are preparing to list but are not yet ready to announce the terms. No price range has been published, no date has been set, and the reporting describes the IPO details as remaining thin. That makes the OpenAI leg of TSMC’s approval harder to assess than the Anthropic leg: there is no market price to compare it with, and no timetable to measure it against. It also means that the $500 million ceiling for OpenAI is, for now, a statement of intent rather than a priced investment, and that the actual amount deployed, and the stake it buys, will depend on negotiations that have not been made public. The contrast between the two legs is instructive: one is tied to a public offering with a published range and a date, and the other is tied to a private company whose public listing is still at the confidential stage, and the board approved both on the same day, in the same session, as if they were the same kind of decision, which they are not.

6. What the Market Made of It

The market’s first reaction to the board’s decisions was positive, at least for TSMC’s own shares. The company’s United States-listed shares rose 2.56 percent on Tuesday, November 10, the day the resolutions were disclosed, according to the reporting of the announcement. That is a modest move for a single day, but it is a clear one, and it suggests that investors read the board’s decisions as good news rather than as a distraction. The rise is worth noting, but it is also worth not over-reading: a single day’s move in a single stock can reflect many things, and the board meeting also produced a record dividend and a very large capital budget, either of which could have moved the shares on its own. What can be said is that the market did not punish the company for deciding to put money into its customers, and that the announcement landed without the kind of scepticism that sometimes greets a manufacturer stepping outside its core business.

6.1 TSMC Shares Rise as the News Lands

The 2.56 percent rise in TSMC’s United States-listed shares on Tuesday is the clearest market signal from the day, and it is worth setting it against the scale of the decisions it was responding to. The shares were reacting to a package, not a single item: the $40.93 billion capital budget, the record dividend, the third-quarter results, and the AI investments were all disclosed together, and any one of them could have been the reason for the move. The capital budget, in particular, is the kind of news that investors in a manufacturer look for, because it signals confidence in future demand, and the record dividend is the kind of news that income investors welcome. The AI investments, by contrast, are small in financial terms, and their effect on the share price is likely to have been indirect, a matter of sentiment rather than arithmetic. That does not make the rise meaningless, but it does mean it should not be read as a verdict on the AI stakes alone. It is a verdict on the package, and the package, taken together, was read as a sign of a company that is confident about its future and willing to spend to secure it.

6.2 How the AI Supply Chain Reads the Move

Beyond the share price, the announcement has been read by the industry as another sign that the AI supply chain is consolidating around a small number of very large players, and that those players are becoming more closely linked to one another. The reporting has described the move as the company that makes AI chips now wanting to own a piece of the AI companies, and that framing captures the way the industry sees it: not as a financial investment, but as a strategic one, a way of binding the supplier to its customers at a time when the demand for computing power is growing faster than anyone can build it. The AI developers have been signing long-term supply agreements, investing in their own chip designs, and in some cases taking stakes in each other, and TSMC’s decision fits that pattern. It is also a sign of how the balance of power is shifting: in the past, the chipmaker was a neutral supplier to all comers, and its neutrality was part of its value, because every designer could trust it with its most advanced work. Taking a stake in two of its customers, even a small one, changes that posture, and the industry will be watching to see whether it changes anything else, whether in the way TSMC allocates capacity, or in the way its other customers view it. For now, the amounts are too small to change the economics, but the signal is large enough to be noticed.

7. The Risks and the Open Questions

For all the attention the announcement has drawn, it leaves a great deal unanswered, and the unanswered questions are worth setting out plainly, because they are the difference between a headline and a transaction. The most important of them is the simplest: the board approved ceilings, not purchases, and until the money is actually spent, and the terms are disclosed, the story is one of permission rather than of fact. The reporting has been careful to make that distinction, and it is worth repeating, because the headline figure of $1 billion is a maximum, not a sum that has changed hands. The second question is about the size of the stakes: no share counts and no ownership percentages were disclosed, so it is not possible to say how much of Anthropic or OpenAI TSMC would own, even if it spent the full $500 million on each. The third is about timing: no closing dates were disclosed for either investment, so it is not possible to say when the money will move, or whether it will move at all.

7.1 Ceilings Are Not Cheques

The distinction between a ceiling and a cheque is the most important thing to understand about the board’s resolutions, and it is the point the reporting has stressed most consistently. A board resolution that authorises up to $500 million in Anthropic shares is permission for the company’s management to spend that much, if it chooses to, on the terms set out in the resolution. It is not a purchase, and it is not a commitment to spend the full amount. The company itself has stressed that the figures are approval ceilings and do not mean the money has been deployed, and that the actual amounts invested, the shareholdings and the completion dates are yet to be disclosed. That is standard practice for a board approval of this kind, and it is not a sign of hesitation, but it does mean that the story is incomplete. The Anthropic leg will become concrete when the IPO prices on November 18, because the price will determine what the $500 million buys, and the OpenAI leg will become concrete only when the terms of the preferred stock are agreed and disclosed, which may take longer. Until then, the $1 billion figure is a ceiling, and it should be described as one.

7.2 Concentration, Conflicts and the Customer Question

There is also a question about what the stakes mean for TSMC’s other customers, and for the company’s long-standing position as a neutral manufacturer. TSMC makes chips for a very wide range of companies, including the rivals of Anthropic and OpenAI, and its value to those companies rests in part on the belief that it treats them all alike. Owning a stake in two of them, even a small one, introduces a question that did not exist before: does the supplier favour the customers it owns a piece of? The amounts involved are small, and the company has given no indication that the stakes will affect how it allocates capacity or sets prices, but the question will be asked, and it will be asked most sharply by the companies that compete with Anthropic and OpenAI. There is also a question about concentration: the AI industry is already dominated by a small number of very large companies, and cross-holdings between them make it more concentrated still. A chipmaker that owns a piece of two AI developers, a cloud provider that owns a piece of a chip designer, a chip designer that owns a piece of an AI developer — the web of holdings is growing, and with it the risk that a problem in one part of the web spreads to the others. None of this is a reason to say the TSMC decision is wrong, but it is a reason to watch what happens next, and to ask whether the company’s neutrality, which has been one of its greatest assets, survives the change.

8. What Happens Next

The next concrete date in the story is November 18, when Anthropic’s offering is expected to price, and that is the date on which the first half of TSMC’s approval will become a real transaction with a real price. Until then, the Anthropic leg is a ceiling attached to a range, and the size of the stake will depend on where in the $70 to $78 range the offering prices, and on whether TSMC spends the full $500 million. The OpenAI leg has no such date, and its timetable is the timetable of a private negotiation, which may take weeks or months, and may or may not be disclosed when it closes. Beyond those two transactions, the story will be measured by what the money does: whether the stakes lead to closer commercial relationships, whether they affect the way TSMC allocates its capacity, and whether other suppliers follow the same path. The $40.93 billion capital budget will take longer to show its effects, because factories take years to build, but it is the decision that will matter most in the long run, because it determines whether TSMC can keep supplying the chips the AI industry needs.

8.1 The Dates to Watch: November 18 and Beyond

November 18 is the date to watch first, because it is the day Anthropic’s offering is expected to price, and the day on which TSMC’s $500 million Anthropic subscription will acquire a price and, with it, a size. Trading is then expected to begin on the Nasdaq under the ticker ANT, and the first days of trading will show whether the market values the company at or near the reported $1.4 trillion, or whether the price settles elsewhere. The private placement of $26 billion, and the list of its participants, will also become clearer around the listing, and TSMC’s role in it, which has been reported but not confirmed in the company’s own filing, may be disclosed. For OpenAI, there is no date to watch, because the company has not set terms for its own listing, and the preferred-stock subscription has no disclosed timetable. The dividend timetable is the other set of dates in the story: the common shares go ex-dividend on March 11, 2027, with a record date of March 17 and payment on April 8, which are the dates on which the record dividend the board approved will actually reach shareholders. Taken together, those dates give the story a shape: a priced transaction in November, a private negotiation with no public deadline, and a dividend payment in the spring.

8.2 The Bottom Line

TSMC’s board has approved up to $1 billion in stakes in Anthropic and OpenAI, up to $500 million in each, alongside a capital budget of about $40.93 billion and a record quarterly dividend, in a single session on November 10, 2026, that shows how completely the AI boom now shapes the world’s largest contract chipmaker. The Anthropic investment would buy ordinary shares at the IPO price, with pricing expected on November 18 and a reported valuation of about $1.4 trillion; the OpenAI investment would buy preferred stock in a private company whose terms, price and timetable have not been disclosed. Both are approval ceilings, not completed purchases, and the actual amounts, shareholdings and closing dates are yet to be disclosed. The decision turns the supplier at the base of the AI supply chain into a shareholder in two of its most important customers, and it is a sign of how entangled the industry has become, and of how confident TSMC is in the demand it sees in its own order books. What is still unconfirmed is whether the full amounts will be deployed, what stakes they will buy, when the OpenAI terms will be agreed, and whether the move changes anything about how TSMC treats its other customers. The coming days will provide the answers.
