Anthropic's IPO is being priced off a number that will not exist for three more years. Anthropic is projecting 2028 revenue of roughly $190 billion to $200 billion, and bankers and investors are using enterprise-value-to-revenue multiples based on that forecast, not current revenue, to price the offering, Reuters reported in August 2026. Read at face value, this is just how growth companies get valued: you pay for where the business is going, not where it is.
It is worth slowing down on how fast that destination has moved. As recently as November 2025, Anthropic's 2028 revenue forecast circulating with investors was about $70 billion, reported by TechCrunch, citing The Information. Nine months later, the number bankers are using is $190 billion to $200 billion, nearly triple. The forecast did not just grow. It grew inside a financing web where the people setting expectations for 2028 are also the people supplying the compute that 2028 depends on.
The names funding growth are the names selling the compute
Anthropic's last private round, a $65 billion Series H that closed May 28, 2026, valued the company at $965 billion post-money, TechCrunch reported, corroborating Anthropic's own announcement. That round sits inside a wider pattern: every major hyperscaler bankrolling Anthropic is also the vendor Anthropic has committed to pay for the compute that generates its revenue.
Google is investing up to $40 billion in Anthropic, $10 billion in immediate cash and up to $30 billion more tied to performance targets, at a $350 billion valuation, alongside a fresh 5-gigawatt TPU capacity commitment over five years, TechCrunch reported in April 2026. Amazon is investing $5 billion more in Anthropic on top of the $8 billion it had already put in, with up to $20 billion further tied to milestones, while Anthropic commits to spend more than $100 billion on AWS over the next decade for up to 5 gigawatts of compute, per Anthropic's own announcement that same month. Microsoft is investing up to $5 billion and Nvidia up to $10 billion, while Anthropic commits to spend at least $30 billion on Microsoft Azure, GeekWire reported in November 2025, five months before the Google and Amazon deals. Adding Amazon's $5 billion, $8 billion and up-to-$20-billion commitments together (our calculation) puts its total potential investment at roughly $33 billion.
Each hyperscaler funding Anthropic is also the vendor collecting its cloud bill.
| Investor | Equity committed (max) | Compute spend Anthropic committed | Anthropic's valuation at that deal |
|---|---|---|---|
| $40 billion | 5 GW of new TPU capacity over five years | $350 billion | |
| Amazon | $33 billion (new, prior and potential) | More than $100 billion on AWS over a decade | not disclosed in the announcement |
| Microsoft and Nvidia | $15 billion combined | At least $30 billion on Azure | not disclosed in the announcement |

None of this is illegal or even unusual on its own; a cloud vendor investing in a large future customer is a standard way this capital gets raised. But it does mean the same four names sit on both sides of Anthropic's ledger: as shareholders benefiting if the 2028 number is believed, and as suppliers whose own committed capacity is part of what has to convert into that number.
What the forward multiple actually buys
Anthropic's own current numbers are real, not projected. Anthropic's run-rate revenue crossed $47 billion in May 2026, up from about $9 billion at the end of 2025, the company's own announcement states, more than a fivefold jump in five months. That is the business the Series H actually priced.
Set the $965 billion Series H valuation against both numbers and the picture changes depending on which one you use. Against the midpoint of the $190 billion to $200 billion 2028 forecast, Anthropic is valued at roughly 4.9 times forward revenue; against the $47 billion current run rate, it is valued at roughly 20.5 times trailing revenue (both our calculation). The forward multiple assumes the 2028 number arrives. The trailing multiple is what the market is actually paying today.
Line that up against how revenue-generating businesses are priced on the Indian exchange. Tata Consultancy Services trades at roughly 3.1 times trailing sales, Screener.in market data show, as of August 2026. Infosys trades at roughly 2.6 times trailing sales, per the same source. Netweb Technologies, India's only listed pure-play AI-infrastructure and HPC maker, trades at roughly 10.6 times trailing sales, also as of August 2026. Anthropic's forward multiple, on a forecast three years out, is still below Netweb's trailing multiple on revenue it has already booked. Anthropic's trailing multiple is almost double Netweb's, and roughly seven times what India's largest IT services company commands on the same basis.
The honest objection
The strongest case for the structure is that vendor financing of this kind is now simply how frontier AI capital gets raised, and that Anthropic's growth is not manufactured. The run rate move from roughly $9 billion to $47 billion in five months is a real, company-reported number, not a forecast. If growth of that speed continues even partway to 2028, a forward multiple in the single digits looks cheap in hindsight, and the hyperscalers' compute commitments are simply the infrastructure that growth requires, offered by the parties best placed to build it fast.
That case weakens once you look at the system these commitments sit inside. The five largest hyperscalers are set to spend over $1 trillion on AI-related capital expenditure from 2025 through 2026, commitments that are outpacing their own earnings and free cash flow, the Bank for International Settlements' 2026 Annual Economic Report states. Bond issuance by the largest investment-grade cloud-computing firms neared $100 billion in the first quarter of 2026 to help fund that buildout, even as the S&P 500's forward price-to-earnings ratio stayed well above its historical median, the Federal Reserve's May 2026 Financial Stability Report states. The same four companies writing checks to Anthropic and selling it compute are themselves borrowing at record pace to build that compute, inside a market already priced for near-perfect execution. A wobble in that financing regime would not just dent Anthropic's suppliers. It would hit its own investor base and its own balance sheet at once.
The Signal
An IPO prospectus can print a $190 billion to $200 billion 2028 number, but it cannot make the four companies that helped write that number disinterested about whether it lands. Watch what Anthropic actually discloses once it reports as a public company: if the revenue run rate keeps compounding toward the forecast on its own commercial merits, the multiple will look prescient rather than circular. Should it stall first, the same four names that priced this IPO, as investors, as compute suppliers and in Amazon and Microsoft's case as balance sheets already carrying record debt to fund the buildout, will be the ones absorbing the gap. A revenue forecast that lives inside its own supply chain is not evidence of demand. It is a promise the promisers wrote to each other, and the IPO market is now being asked to cosign it.
Reporting basis: the IPO valuation methodology and the $190 billion to $200 billion 2028 revenue forecast are per Reuters, as carried by Investing.com. The Series H terms and valuation are as reported by TechCrunch, corroborating Anthropic's own announcement; the $47 billion run rate and $9 billion year-end 2025 figures are from that same Anthropic announcement. The Google investment and compute terms are per TechCrunch's reporting; the Amazon investment and AWS spending commitment are per Anthropic's own announcement; the Microsoft, Nvidia and Azure terms are per GeekWire. The November 2025 $70 billion forecast is per TechCrunch, citing The Information as the original source. The hyperscaler capital-expenditure figures are from the Bank for International Settlements' 2026 Annual Economic Report, and the bond-issuance and equity-valuation figures are from the Federal Reserve's May 2026 Financial Stability Report. The TCS, Infosys and Netweb Technologies trading multiples are Screener.in market data as of August 2026. The Amazon total commitment, the forward and trailing revenue multiples on Anthropic's Series H valuation, and the comparison against the three India-listed multiples are all The Signal's calculations from those figures.
