VCs will make billions on Anthropic’s IPO, but Amazon is set to make much (much) more

Many investors basal to triumph large erstwhile Anthropic goes public. Stakes held by firms including Menlo Ventures, Sequoia, Sound Ventures, and Spark Capital are expected to return billions.

Yet according to Anthropic’s S-1, nary of those VC firms owns 5%, the threshold for being included successful the main stockholders’ table. That’s highly unusual. In a emblematic tech IPO, pb task investors clasp double-digit-percentage stakes successful the startups they backed. The crushed is Anthropic’s size. At its $965 cardinal backstage valuation, a 1% involvement is worthy astir $10 billion, so, for example, Menlo’s astir $14 cardinal position is lone astir 1.5% of the company, according to recently reported Bloomberg figures.

While the task firms whitethorn deficiency sizable percent stakes, Anthropic sold ample stakes to strategical partners, companies that are besides its concern partners. Indeed, Amazon is apt the azygous largest fiscal beneficiary of the IPO.

Amazon archetypal backed Anthropic successful 2023 with a committedness to put up to $4 billion successful the AI company. Since then, Amazon has poured billions much into Anthropic. Instead of taking banal upfront, Amazon structured overmuch of its concern arsenic convertible notes, a benignant of indebtedness that converts into shares upon an IPO oregon sale.

According to the S-1, Amazon holds convertible notes with $6.2 cardinal successful main outstanding arsenic of June 30. That is Anthropic’s full indebtedness load. But arsenic Anthropic’s valuation soared crossed successive backing rounds, the shares those notes volition person into became acold much valuable. Amazon’s ain filings valued its enactment holdings astatine $97.9 billion arsenic of June 30.

As the worth of Amazon’s convertible notes surged, Anthropic had to grounds the increasing worth of what it owes connected its books. It reported the adjustments connected its income connection nether “change successful just worth of convertible notes, derivative liabilities, and SAFEs,” a enactment that totaled $72.4 cardinal for the archetypal fractional of 2026. The complaint is non-cash, meaning nary wealth near the company.

Amazon’s notes could person into arsenic galore arsenic 1.84 cardinal shares, according to the S-1. But a headdress limits Amazon to 12% of Anthropic’s “partially diluted” stock count, a fig that counts immoderate shares not yet issued, specified arsenic banal options. Amazon tin waive the cap. Notes that can’t person volition enactment outstanding and person successful aboriginal quarters, taxable to the aforesaid limit.

But the notes are lone portion of Amazon’s holdings. It further invested $10 cardinal successful nonvoting preferred banal (a benignant of equity), successful the 2nd quarter, according to Amazon’s quarterly study for the play ended June 30. Amazon did this by investing $5 cardinal successful each of Anthropic’s past 2 backing rounds. Combined with the $8 cardinal it invested successful the notes from 2023 done 2025, that brings Amazon’s full concern to astir $18 billion.

Beyond its banal gains, Amazon volition besides proceed to gain important gross from Anthropic, which has committed to walk astatine slightest $110 cardinal connected AWS implicit the adjacent 10 years.

Google, too, is acceptable for a large windfall from some the listing and its unreality computing deals with Anthropic. The hunt elephantine held astir 14% of Anthropic arsenic of aboriginal past year, according to court filings that were reported by The New York Times, and has invested much since, including $10 cardinal successful April. (Google was apt diluted successful consequent and monolithic backing rounds, with PitchBook expert Harrison Rolfes telling TechCrunch helium estimates its existent involvement astatine person to 5.6%.) It has besides secured astatine slightest $114 cardinal successful unreality commitments from the Anthropic done 2033.

While VCs acceptable for monolithic paydays person small crushed to complain, the S-1 makes it wide that the biggest winners of Anthropic’s IPO whitethorn good beryllium tech giants similar Amazon, which backed a would-be rival aboriginal connected and present merchantability it overmuch of the computing powerfulness it runs on.

The S-1 itself warns that immoderate of those unreality providers besides physique rival AI models and that they whitethorn not ever privation the aforesaid things that Anthropic does.
