Anthropic would hold about $212.7 billion of cash, cash equivalents and short-term investments after its IPO and concurrent private placement, pro forma at 30 September, its S-1/A of 10 November shows. That is about 3.8 times the $56.6 billion of cash, cash equivalents and marketable debt securities Nvidia held on 26 July, the latest balance-sheet date in its 10-Q, by our arithmetic.
Nvidia is one of the buyers: the $10.0 billion of Anthropic stock it agreed to buy in the $26.0 billion placement is part of that pro forma figure. Before the IPO, Anthropic’s actual $131.8 billion at 30 September was already about 2.3 times Nvidia’s figure, by our arithmetic.
Business Pill · Seller Financing
An evergreen Business Engineer explainer on seller financing: when the seller also becomes the lender. It teaches the general idea only and does not discuss Nvidia or Anthropic.
The key insight: As we read the two filings, the funding now runs from customer to supplier in size: Anthropic, which lists NVIDIA GPUs in its multi-chip compute architecture, would hold about 3.8 times Nvidia’s cash after its IPO, by our arithmetic, and about $10.0 billion of that new cash is Nvidia’s own purchase of Anthropic stock.
Anthropic’s capitalization table puts cash, cash equivalents and short-term investments at $131,845 million on an actual basis and $212,684 million pro forma as adjusted at 30 September. The adjusted column gives effect to the sale of 801,351,354 Class A shares in the IPO and 351,351,348 Class N shares in the placement, both at the assumed $74.00 midpoint. With the underwriters’ option exercised in full, the filing says the figure would be $221.7 billion.
The balance sheet splits the actual figure into $95,562 million of cash and cash equivalents and $36,283 million of short-term investments, which a note lists as commercial paper, U.S. Treasury and agency securities and corporate debt securities.
Nvidia’s 10-Q for the quarter ended 26 July shows $22,443 million of cash and cash equivalents and $34,143 million of marketable debt securities, which its liquidity table adds up as “Cash, cash equivalents, and marketable debt securities” of $56,586 million. As we read the two filings, both lines are cash plus short-term debt holdings. Nvidia’s $42,783 million of marketable equity securities sits outside its figure.
Anthropic’s cash, cash equivalents and short-term investments at 30 September 2026, actual and pro forma as adjusted after its IPO and concurrent private placement (S-1/A No. 2, 10 November 2026), against Nvidia’s cash, cash equivalents and marketable debt securities at 26 July 2026, the same plus marketable equity securities, and its $169.5 billion of equity investment commitments, AI cloud service commitments and maximum guarantee exposure (10-Q filed 26 August 2026). The ratios, the $99.4 billion and the $169.5 billion sum are our arithmetic.
The Ratios, by Our Arithmetic
Anthropic’s pro forma $212.7 billion is about 3.8 times Nvidia’s $56.6 billion, or about 3.9 times with the underwriters’ option. Its actual $131.8 billion is about 2.3 times. The IPO and placement alone add about $80.8 billion ($212,684 million less $131,845 million), about 1.4 times Nvidia’s whole figure.
Counting Nvidia’s marketable equity securities as well, its liquid holdings were $99.4 billion, and Anthropic’s pro forma figure is about 2.1 times that.
The 10-Q also lists $25 billion of equity investment commitments and $36 billion of AI cloud service commitments at 26 July, plus $108.5 billion of maximum guarantee exposure including the SB Energy guarantees signed in August. Those add up to $169.5 billion, as set out in our piece on Nvidia’s ecosystem pledges. Anthropic’s pro forma cash is about 1.25 times that sum, or $43.2 billion more. The $169.5 billion is commitments and guarantee caps, not cash already paid out.
Nvidia’s Money Inside Anthropic’s Pile
The S-1/A says NVIDIA would buy 135,135,135 Class N shares for approximately $10.0 billion at the $74.00 midpoint, one of seven buyers in the placement, as listed in our buyer-by-buyer split of the placement. The filing estimates net proceeds from the IPO and the placement at approximately $84.6 billion at that price.
Nvidia’s $10.0 billion is about 12.4% of the $80.8 billion the IPO and placement add to Anthropic’s cash, 4.7% of the pro forma $212.7 billion and 17.7% of Nvidia’s own $56.6 billion, by our arithmetic. The purchase agreement can end in four ways, set out in our piece on the four exits.
Stock Versus Flow
The two figures were built differently. Anthropic’s S-1/A says it had raised an aggregate of $141.1 billion of capital by 30 September; its $131.8 billion equals about 93% of that, by our arithmetic, as our piece on Anthropic’s cash pile set out.
Nvidia’s 10-Q shows $74,421 million of net cash provided by operating activities in the six months to 26 July, about 1.3 times its 26 July figure, by our arithmetic. In the same half it spent $42,404 million on purchases of equity securities, the 10-Q’s cash flow statement shows.
As we read the filings, Anthropic’s figure is mostly raised capital: its $131.8 billion is about 93% of the $141.1 billion it says it had raised by 30 September, by our arithmetic, while Nvidia’s operations provided $74.4 billion of cash in the six months to 26 July.
As we read the placement, money moves both ways between the two companies: Anthropic’s S-1/A lists NVIDIA GPUs in its compute architecture, and Nvidia has agreed to buy approximately $10.0 billion of Anthropic stock at the IPO price.
Anthropic, PBC, Form S-1/A, 10 November 2026
“As of September 30, 2026, we had raised an aggregate of $141.1 billion of capital”
Three Implications
FOR THE IPO PRICING The $212.7 billion assumes the $74.00 midpoint; the filing says the pro forma figures are illustrative and adjusted at pricing, and puts the figure at $221.7 billion with the underwriters’ option in full.
FOR NVIDIA’S BALANCE SHEET The 10-Q items behind the $169.5 billion of commitments and guarantee caps come to about 3.0 times Nvidia’s $56.6 billion, and the Anthropic purchase equals 17.7% of that cash figure, by our arithmetic.
FOR THE OTHER PLACEMENT BUYERS The S-1/A puts Google’s purchase at approximately $10.0 billion as well, the same as Nvidia’s, at the $74.00 midpoint.
The framework argues: “It is a sovereign-scale financing problem dressed in tech-company clothing — and the financial architecture is starting to invert.”
As we read it, a model lab that would hold about 3.8 times its chip supplier’s cash, by our arithmetic, partly funded by that supplier, is one form of that inversion. The framework predates both filings and does not discuss them.
What Is Not Established
The balance-sheet dates differ: Anthropic’s figures are at 30 September and Nvidia’s at 26 July, and neither includes cash flows since. Anthropic’s filing says the pro forma as adjusted information “is illustrative only and will be adjusted based on the actual initial public offering price and other terms of this offering determined at pricing”.
We compared cash and short-term holdings only, and did not net out debt or other liabilities on either side. The 10-Q we read does not name Anthropic, so it does not show whether the purchase is part of the $25 billion of equity commitments. We did not contact Anthropic or Nvidia for this piece.
This Week In The AI Supercycle
AI Lost Its Central Banker, the Lab Oligopoly, and the Future of Open Source
This week’s issue: the Nvidia leadership change, read as the AI build-out losing its central banker: who now finances the GPU landlords, backstops the data centres and sponsors open models, and why two labs are becoming the bank.
On their latest filings, Anthropic would hold about $212.7 billion of cash and short-term investments after its IPO and placement, about 3.8 times Nvidia’s $56.6 billion at 26 July and about 1.25 times Nvidia’s $169.5 billion of commitments and guarantee caps, by our arithmetic. About $10.0 billion of that new cash is Nvidia’s own purchase.
A note on sourcing. We read Anthropic’s S-1/A No. 2, filed with the SEC on 10 November 2026, and Nvidia’s 10-Q for the quarter ended 26 July 2026, filed on 26 August 2026, on SEC EDGAR on 13 November: the balance sheets, Anthropic’s capitalization table and placement terms, and Nvidia’s liquidity table, commitments, guarantees and cash flow statement. The comparison draws on our earlier pieces linked above. Ratios, sums and percentages are our arithmetic. We did not contact Anthropic or Nvidia for this piece.
