Anthropic prepares its market debut at $2 trillion: Amazon and Google get paid twice, as shareholders and as cloud providers

By Zendoric · September 6, 2026.

Anthropic, the company behind the chatbot Claude, is reportedly preparing to go public in the coming weeks, with the offering's prospectus — the document with accounts and risks that every company must file before listing — ready as soon as next week. So reports Benzinga, citing the Financial Times on the allocation of roles among the underwriting banks. The figure being floated: a $2 trillion valuation, which would make Anthropic the company that has reached that mark fastest in corporate history.

Caution is warranted with that figure. None of this has been confirmed by Anthropic; these are "expected" numbers that the article reports without specifying their source, and both the timetable and the valuation could move before a real, verifiable prospectus exists. We treat this as what it is: the best information available today about a deal that has not yet happened.

In the allocation of roles, Morgan Stanley would take the "lead left" — the position of the bank heading the underwriting syndicate, which usually takes the largest share of fees — while Goldman Sachs would act as stabilization agent, the bank in charge of buying and selling shares after the debut to contain volatility in the stock. For scale: in SpaceX's IPO, the underwriting banks shared more than $500 million in fees, with $100 million each for Goldman and Morgan Stanley, as the article itself recalls. JPMorgan, Citigroup and Barclays would be in line for lesser roles.

Among the shareholders, Amazon is the lead investor by cumulative amount: some $8 billion invested so far, plus an additional $6 billion commitment this year, with AWS as the main cloud for training Anthropic's models. If the $2 trillion valuation holds, Amazon's stake could exceed $420 billion, a figure equivalent to close to 15% of Amazon's own market value ($2.8 trillion). Alphabet, for its part, holds a 14% stake in Anthropic, which at that valuation would be worth around $280 billion.

One technical detail the article notes and that deserves emphasis: Anthropic trains its models largely on chips from Google (TPUs, in-house processors designed by Alphabet as an alternative to Nvidia's GPUs) and from Amazon, and not primarily on Nvidia hardware. It is a structural difference from OpenAI, which does depend heavily on Nvidia. Microsoft and Nvidia appear as investors, but they arrived late and their returns would be smaller; the list of participants is rounded out by Salesforce, Cisco, Zoom, and the funds Coatue, Lightspeed Ventures and Menlo Ventures.

As sector context, this deal would arrive in the middle of a window of AI company listings and at a time when the private market has already normalized valuations that three years ago would have seemed like science fiction for a company without a decade of history.

Our reading: this is a variation on the same capital circularity pattern we have already flagged in the relationship between Nvidia and other AI labs. When your cloud and chip provider is also your main shareholder, the gains being announced are not just the appreciation of an independent financial bet: they are also the validation of the tens of billions that Amazon and Google have already committed to infrastructure to serve precisely that customer. Before taking at face value any growth figure that appears in the final prospectus, one will have to separate how much of that business is real third-party demand and how much is intragroup spending between Anthropic and its own investor-providers.

There is also an underlying reading about who captures the value in this phase of AI. The big beneficiaries of a $2 trillion IPO — banks with multimillion-dollar fees, and two of the five most valuable companies in the world — are the same players that already dominate the digital economy. It is consistent with what we have been arguing: in the short term, the value generated by AI is concentrated in very few hands. The long-term promise — an abundance shared more widely, starting with the fact that going public finally opens access to public investors who cannot touch this business today — is only fulfilled if that initial concentration does not become a permanent structure.
