Amazon disclosed on Friday that its investment in AI startup Anthropic has escalated to a staggering $60.6 billion, based on its holdings of $45.8 billion in convertible notes and $14.8 billion in nonvoting preferred stock. This substantial valuation comes after Amazon’s cumulative investment of $8 billion in Anthropic since late 2023, indicating a seven-fold increase in the startup’s worth. If this valuation holds, it would rank among Amazon’s most lucrative strategic technology investments.
The commercial relationship between Amazon and Anthropic is robust. Anthropic has committed to purchasing 1 million of Amazon’s Trainium chips, which further ties one of the leading AI laboratories to Amazon Web Services. This partnership underscores Amazon’s aim to solidify its position in the competitive cloud and AI markets.
Anthropic’s financial trajectory has been impressive, with the company last securing $13 billion in funding in September at a post-money valuation of $183 billion. Prior to that, a $3.5 billion funding round in March valued Anthropic at $61.5 billion. Current discussions for another funding round could potentially elevate its valuation to $350 billion, reflecting the strong investor interest in AI technologies.
The convertible notes Amazon holds convert to preferred stock as Anthropic raises additional capital, allowing Amazon to gain shares every time the startup closes a funding round. This arrangement has already yielded positive effects on Amazon’s earnings; conversions in 2025 generated approximately $5.6 billion in recognized gains, alongside a $7.2 billion upward adjustment to its “other income” in the third quarter, driven by Anthropic’s rising valuation.
An Amazon spokesperson reported that the value of the company’s stake in Anthropic increased from $38.5 billion in the third quarter to $60.6 billion in the fourth quarter of 2023. The company anticipates a further gain of $15 billion in the first quarter’s “other income” due to additional conversions of the notes into nonvoting preferred stock.
It is important to note that these valuations are based on “significant judgment,” as Amazon categorized its convertible notes as “Level 3” assets. This classification indicates that their values derive from unobservable inputs and Amazon’s own assessments rather than from market prices. Such valuations are common for stakes in private startups, which lack regular trading on public markets.
The interest in Anthropic is not limited to private investments; the company is reportedly considering an initial public offering (IPO) within the year, which could significantly alter its valuation landscape. The potential IPO reflects the ongoing transformation in the AI sector, as investors increasingly seek opportunities in companies poised for rapid growth.
As the AI landscape continues to evolve, Amazon’s strategic investment in Anthropic positions the company to capitalize on a burgeoning market that is set to reshape various industries. The partnership not only strengthens Amazon’s technological offerings but also highlights the competitive dynamics between major players in the AI field, such as Nvidia, OpenAI, and Google.
