Analysis
Anthropic's venture investors are positioned to collect billions once the company goes public, but Amazon's financial exposure to the IPO dwarfs any VC firm's, according to TechCrunch's analysis published October 27, built on Anthropic's own S-1 disclosures.
## The VC math At Anthropic's most recent private valuation of $965 billion, a 1% stake is worth nearly $10 billion.
Menlo Ventures, Sequoia, Sound Ventures and Spark Capital all hold positions TechCrunch says are "expected to return billions," with Menlo's stake alone estimated at roughly $14 billion, or about 1.5% of the company, per Bloomberg figures cited in the piece. Notably, the S-1 itself does not name any VC firm individually in its principal-stockholders table, because none holds the 5% threshold required for disclosure -- meaning the firms standing to make the most money are the ones investors can see least clearly in Anthropic's own filing.
“## The VC math At Anthropic's most recent private valuation of $965 billion, a 1% stake is worth nearly $10 billion.”
- ## Amazon's much larger position
- Amazon's exposure to Anthropic has grown step by step:
- 2023 commitment -- up to $4 billion
- 2023-2025 notes -- $8 billion in convertible notes
- Q2 2026 -- $10 billion in nonvoting preferred stock
- Current notes outstanding -- $6.2 billion, effectively Anthropic's entire debt load as of June 30
Amazon's own filings value those current notes at $97.9 billion. They could convert into as many as 1.84 billion Anthropic shares, though a cap otherwise limits Amazon to 12% of the company's partially diluted share count -- a cap Amazon can waive. Including every commitment above, Amazon's total investment comes to roughly $18 billion, a fraction of the $97.9 billion fair-value mark its notes already carry on paper.
## The AWS relationship behind the numbers Anthropic has committed to spend at least $110 billion on AWS over ten years, a figure that helps explain why Amazon's financial stake has appreciated so far beyond its cash invested: the note structure effectively lets Amazon capture equity-like upside from a customer relationship it also controls commercially. Anthropic's income statement shows a $72.4 billion non-cash charge for the first half of 2026 tied to the "change in fair value of convertible notes, derivative liabilities, and SAFEs" -- an accounting reflection of exactly how much Amazon's position, and others like it, has appreciated as Anthropic's valuation climbed.
## Google's diluting stake Google held roughly 14% of Anthropic as of early 2025, per court filings, and invested $10 billion more in April 2026. Despite the additional capital, PitchBook analyst Harrison Rolfes estimates Google's current stake has fallen to closer to 5.6%, diluted by the scale of Anthropic's subsequent mega-rounds. Google has separately locked in at least $114 billion in cloud commitments from Anthropic through 2033, mirroring the Amazon pattern of a strategic investor whose commercial relationship and equity stake move together.
## What the headline misses The eye-catching framing -- VCs making billions -- understates how concentrated the real winners are. Amazon and Google's combined exposure, built on commercial contracts worth hundreds of billions over a decade, functions less like venture investing and more like vendor financing with equity upside attached. Anthropic's own S-1 discloses the compute commitments driving this dynamic, and the risk for traditional VCs is that strategic investors with commercial leverage keep capturing a disproportionate share of the upside in every subsequent AI mega-round, not just this one.
## What becomes real None of these figures are final until Anthropic's IPO actually prices, likely within the next month by Fortune's account. Whether Amazon chooses to convert its notes, waive its 12% cap, or simply hold convertible debt through the listing will determine how much of that $97.9 billion fair-value mark becomes real, realized equity rather than a balance-sheet estimate.
