Amazon's Anthropic position is likely going to be worth than most AMZN holders can imagine
I think Anthropic is materially undervalued even at its current ~$1T valuation (FT reporting, May 8). On my bottom-up analysis, Anthropic gets to $600B ARR by 2030 and $1T ARR by 2034. At those numbers, the company is worth multiples of where it's marked today. Every current valuation discussion is anchored too low.
What that means for AMZN holders:
The equity stake. Amazon's $8B investment in Anthropic is now worth over $70B on the balance sheet (Fortune, April 30, Amazon-confirmed). 8.75x markup, triggered by Anthropic's Series G at a $380B post-money valuation in February. The FT reported last week Anthropic is now in talks at $900B to $1T. If that round closes, Amazon's stake goes to roughly $165-185B. Another massive non-operating gain hitting AMZN earnings, possibly this year. And on my numbers, even $1T is still too low.
The AWS revenue. Anthropic committed to $100B+ in AWS spend over 10 years. Roughly $10B/year at full deployment. AWS did $108B total in 2024, so this is one customer signing up for ~10% of AWS's current annual revenue, locked in. Anthropic's ARR went from $9B at end of 2025 to $45B last week. Five-fold in five months. The AWS contract is sized for a trajectory that lands well into the hundreds of billions of ARR by 2030.
And it's all running on Trainium. Amazon's custom silicon. Every dollar of inference Anthropic runs on Trainium instead of NVIDIA is margin retained inside Amazon. Trainium + Graviton combined is already over $10B annual run-rate, growing triple digits YoY. The Anthropic deal is the commercial proof that custom silicon works at frontier scale.
Most AMZN sell-side models I've seen barely account for any of this as a discrete value driver, and they're definitely not modelling the equity stake at anywhere near my fair value for Anthropic.
If you want the full anthropic analysis for how I get to $600bn in revenue by 2030, I'll leave my long form analysis in the comments (no paywall).
