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

Amazon's strategic investment in Anthropic is projected to yield profits dwarfing those of venture capitalists.

Venture capital firms are poised to gain billions from Anthropic's upcoming Initial Public Offering (IPO), with stakes from investors like Menlo Ventures and Sequoia expected to yield significant returns. However, the article highlights that Amazon is set to realize substantially greater profits. Amazon initially invested up to $4 billion in Anthropic in 2023, structuring much of it as convertible notes. As of June 30, these notes had a principal outstanding of $6.2 billion, but Amazon's filings valued them at $97.9 billion due to Anthropic's soaring private valuation. This surge in value, a non-cash adjustment for Anthropic, amounted to $72.4 billion in the first half of 2026. Beyond the convertible notes, Amazon also invested $10 billion in nonvoting preferred stock, bringing its total investment to approximately $18 billion. Additionally, Anthropic has committed to spending at least $110 billion on Amazon Web Services (AWS) over the next decade. Google also stands to benefit, having invested significantly and secured at least $114 billion in cloud commitments from Anthropic through 2033.

The structure of Amazon's investment, primarily through convertible notes, allowed it to capitalize on Anthropic's exponential private valuation growth, turning a multi-billion dollar debt obligation into a potentially massive equity gain. This strategy underscores how large tech companies can leverage their balance sheets and strategic partnerships to secure significant financial upside in the AI race, beyond direct equity ownership.

This situation signals a new dynamic in AI company funding, where hyperscalers like Amazon and Google are not just customers but also major financial beneficiaries, potentially eclipsing traditional VC returns. Their large-scale cloud commitments alongside financial investments create a symbiotic, yet complex, relationship, with Anthropic's S-1 filing cautioning about potential conflicts of interest with these powerful partners who also develop competing AI models.
