“…we committed to spend at least approximately $121.3 billion between April 2026 and July 2033, regardless of actual usage.”
That line sits on page 180 of the amended prospectus Anthropic filed on November 10, and it describes the company’s cloud contract with Google. On page 20 of the same document, Google agrees to buy $10 billion of Anthropic stock the moment the IPO closes.
Much of the coverage of this week’s roadshow has listed the second fact as a show of support. Anthropic is offering 825 million shares at $70 to $78, a fully diluted valuation of up to about $1.4 trillion, with pricing expected November 18 and Nasdaq trading under the ticker ANT expected the next day. Alongside it, seven of the biggest names in computing will buy $26 billion of non-voting Class N stock at the IPO price. CNN called it a blockbuster, and on size alone it is one.
Read the allocation against the contracts, though, and the vote looks different. At the $74 midpoint, the filing has Google and Nvidia buying $10 billion each, AMD $2.5 billion, Broadcom, Micron and Microsoft $1 billion each, and TSMC $500 million. The same filing says Anthropic has committed at least $121.3 billion to Google, plus an estimated $125 billion to $150 billion more in Google TPU capacity that is not even in its obligations table, and at least $47.2 billion to Microsoft through June 2033. Both contracts are non-cancelable and owed whether Anthropic uses the compute or not.
So for every dollar Google puts into Anthropic’s stock, Anthropic has already promised Google about $12 back in cloud spending, before the extra TPU deal. For Microsoft the ratio is roughly 47 to one. Those are our calculations from the prospectus figures, and they are the numbers missing from almost everything written about the placement so far.
None of this is hidden, and none of it is unusual in this industry, where chip and cloud companies have spent two years investing in the customers who buy their capacity. That is the point. A supplier buying its customer’s stock is protecting a receivable as much as it is making a bet, and the $26 billion is about 2.9% of the $900.9 billion in compute and infrastructure commitments Anthropic disclosed. It covers a little over a third of the $70.7 billion due in just the next 12 months.
One more detail public buyers should notice. The prospectus says the placement shares “will not be subject to market standoff agreements with us or lock-up agreements with the underwriters.” They are restricted securities, so they cannot hit the public market without registration or an exemption, and some of the buyers hold registration rights. But they sit outside the lock-up that binds most insiders, which is a different position from the one a retail buyer takes on November 19.
Our view: the placement is real money and the commitments are real obligations, and investors should price them together, not treat the first as an endorsement of the second. A retail investor buying ANT at the open is not standing where Google is standing. Google gets paid on the cloud contract whatever the stock does. You do not.
The filing builds on the original S-1, which we broke down when it showed $16.3 billion in revenue against an $80.7 billion loss. Anthropic has already had one stumble on terms since. It pulled a first filing of roughly 867 million shares at $70 to $80, saying some pricing information was inaccurate, and the range now sits below the roughly $2 trillion valuation floated weeks ago. The Financial Times reported, in a story Fortune picked up, that bankers are considering pricing above the range anyway. If they do, the strategic buyers pay more per share too, and the ratios above shrink a little. The contracts do not.
The next test comes in the first quarterly filing after the listing, when Anthropic will have to show how much of that $70.7 billion it has spent, with whom, and whether revenue is keeping pace.
