TSMC's board approved $1.5 billion of Anthropic and OpenAI equity, and joined the anchor book

TSMC's▼−2.68% — TSMC, down 2.68 percent today board on November 10 approved $1.5 billion of new equity commitments: up to $500 million of AnthropicPVT$350B — Anthropic, private, latest valuation $350B common shares at the IPO price, up to $500 million of OpenAIPVT$1.18T — OpenAI, private, latest valuation $1.18T preferred stock, and $500 million to set up a new investment company for strategic semiconductor holdings ¹. The same session authorized $40.93 billion of capital appropriations for capacity, packaging and fab construction ¹. TSMC has spent decades selling wafers to everyone; it is now an equity holder in customers it supplies.

The placement extends past the board cap. Anthropic's $26 billion private placement, priced at the IPO price, names TSMC's investment arm alongside Google, Nvidia▼−3.21% — Nvidia, down 3.21 percent today, AMD▼−10.90% — AMD, down 10.90 percent today, Microsoft▼−0.28% — Microsoft, down 0.28 percent today, Broadcom▼−6.53% — Broadcom, down 6.53 percent today and Micron▼−4.50% — Micron, down 4.50 percent today, who together committed a further $6 billion ²⁵. Anthropic's own prospectus↗ describes heavy reliance on TSMC for advanced chip manufacturing ⁵. So the supplier of nearly every frontier chip is now an anchor investor in the labs buying those chips.

Supplier equity now funds the compute orders

Follow the money one hop and the loop closes. Anthropic's filing↗ books about $900.9 billion of compute and infrastructure commitments, $70.7 billion of it due within twelve months, against $146.6 billion of liquidity as of September 30 ².

Goldman Sachs▼−0.23% — Goldman Sachs, down 0.23 percent today projects $136 billion of 2027 sales against a $65.7 billion free cash flow burn that year ². Anthropic funds that gap with equity: the IPO, the placement, and the suppliers who now own stakes in the customer. TSMC's Anthropic block executes only if the IPO closes, at the $70 floor of the $70 to $78 range, and the IPO prices on November 18, with trading on Nasdaq from November 19 ¹².

Investors moved from Nvidia into the supplier

Meanwhile the market has already repriced the neutral supplier. Nvidia chief executive Jensen Huang resigned this week after revelations about his personal affairs, and the 11% slide in Nvidia shares↗ sent investors into TSMC, up 11%, as the safer AI play that wins whichever chip designer does ³. TSMC added 0.9% on Friday as the Taiex, Taiwan's benchmark index, rose 1.7% ⁴.

The November 18 print is the test

The test is the November 18 print ¹². If the $26 billion anchor book holds, the customers prepaying for TSMC's 2027 and 2028 capacity are cash-funded and the demand behind October's 59.7% sales growth↗ is bankable ¹². If the book shrinks at pricing, those prepayments rest on thinner equity, and TSMC's newest shareholders will learn that owning the customer is a second, correlated bet on the same capacity they sold.

The filing shows the exposure is bigger than $500 million, and it is tied to a price set five days from now ¹²⁵.
