TSMC to invest $1 billion in OpenAI and Anthropic, closing the AI money loop once again

Imagine a bakery that supplies bread to the two biggest café chains and then buys stakes in those same chains. Sales grow, while part of the revenue flows back to the buyers so they order even more bread. That is roughly the picture painted by the news about TSMC.

What exactly happened

The board of directors of the world's largest contract chipmaker approved a plan to invest up to $1 billion in OpenAI and Anthropic. According to Reuters, up to $500 million will go into OpenAI preferred shares reserved for large investors. Another $500 million will go into Anthropic common shares at the expected price of its IPO.

As a result, TSMC will get direct stakes in two leading model developers. Previously, the company profited from the AI boom indirectly, through orders to manufacture chips for data centers.

Why this is called circular financing

TSMC's fabs physically produce the overwhelming majority of Nvidia's chips for AI data centers. They also make most of Apple's custom chips for the iPhone, Mac and a future AI server. The main fabs are in Taiwan, but there is production in Japan and China, a growing cluster in Arizona and a plant under construction in Germany.

OpenAI and Anthropic, in turn, buy huge volumes of the hardware that TSMC makes. The result is a chain: an investor gives money to a developer, the developer buys chips, the supplier receives revenue and puts it back in. Nvidia has gone down the same path: $30 billion into OpenAI and $10 billion into Anthropic, plus tens of billions more into other AI and robotics companies.

The Wall Street Journal writes that such a move could give the market a "jolt of confidence" while the AI deal is coming apart at the seams. But the same analysts warn: when money moves among investors, suppliers and customers, it is hard to tell where real demand ends and demand sustained by the participants themselves begins.

How worrying is it

In scale, the deal is modest. From July to September 2026, TSMC earned more than $23 billion in net profit, and profit has been a record for six quarters in a row. One billion dollars is about 4% of a single quarter's profit. Nvidia's investments in the same two companies are an order of magnitude larger.

Moreover, this is not a desperate attempt to hold on to customers. The company has excess cash and is buying a stake in the potential winners of the market. But the symbolism matters: even the most "down-to-earth" player in the chain, the silicon maker, is now betting on those who buy its products.

What practitioners should do about it

It is too early to panic, but there are three takeaways, and these are our interpretation, not facts from the source.

• Don't tie your product to a single provider. If the market swings, access terms and API prices may change. An abstraction layer over models (a router or a unified interface) is cheap and protects against unpleasant surprises.
• Calculate unit economics honestly. Don't build current inference prices into your business model as if they were permanent: part of the market lives on venture and strategic money.
• Read reports with caution. Record chip orders and growth in suppliers' revenue are a signal, but one partly "heated up" by their own investments.

Watch the Anthropic IPO: the offering price will show how much the market really values such a circular model.

Limitations

We only know what Reuters and the WSJ have reported: the board approved the plans, but has not completed the deal. The terms (timing, stakes, company valuations) are not disclosed in the reporting. So it is too early to talk about a "bubble." But the fact that the deals are circular is already worth keeping in mind when making any decision to bet on a particular AI provider.
