In the high-stakes world of artificial intelligence, Amazon’s evolving partnership with Anthropic is becoming a headline event—and not just for tech nerds. Anthropic, a red-hot AI startup founded by ex-OpenAI engineers, is now at the center of a multibillion-dollar tug-of-war between Amazon and Google. While Amazon has pledged up to $8 billion to support Anthropic (making it the AI firm’s “primary cloud and training partner”), Bloomberg recently reported that Anthropic is negotiating a separate cloud computing deal with Google. The talks reportedly involve tens of billions of dollars and access to Google’s AI chips—a move that could shake up Amazon’s long-term AI strategy.
This isn’t just about one startup. Anthropic is the second most prominent name in AI after OpenAI, and Amazon is counting on it to showcase the power of AWS and its custom AI chips like Trainium2. With Google elbowing in and the broader AI cloud war heating up, the battle lines are drawn—and the next few months could redefine who leads in AI infrastructure.
AWS & Trainium: Betting Big On Custom Silicon
Amazon isn’t just renting out servers anymore—it’s building the silicon that powers tomorrow’s AI. And Anthropic is ground zero for that strategy. Amazon’s custom-built Trainium2 chips are already being used to train Anthropic’s newest Claude models, a major validation of AWS’s in-house capabilities. Trainium2 promises up to 40% better price-performance versus traditional GPUs. For cost-sensitive enterprise clients looking to scale AI applications, that’s a big deal.
This strategy isn’t just about hardware, though. It’s about vertical integration. Amazon is positioning itself as a full-stack AI provider—from infrastructure to chips to foundation models via Bedrock. And it’s working. Bedrock now includes Anthropic’s Claude 4, the fastest-growing model on the platform, as well as Amazon’s own Nova.
With Anthropic leaning into AWS for both training and deployment, Amazon’s pitch to enterprise customers gets stronger: “If it works for Claude, it’ll work for you.” That narrative drives credibility in a cloud market where trust and performance matter more than ever.
Prime Network Effects & Anthropic’s Real-World Use Cases
Anthropic isn’t just an R&D trophy—it’s already driving real usage that Amazon can monetize across its vast platform. Think of it this way: Anthropic’s Claude models are increasingly being used in enterprise software, customer service bots, internal dev tools, and more. Every Claude interaction routed through AWS is a monetizable event. That’s traffic. That’s data. That’s infrastructure scale. And it’s sticky.
Now layer on Amazon’s ecosystem. Alexa+ is being upgraded with generative AI. Developers are building with tools like Kiro (Amazon’s new AI coding agent), and Bedrock’s customer list is growing. Anthropic supercharges all of that. It’s not just about renting GPU cycles—it’s about owning a piece of the GenAI stack that underpins the next generation of cloud apps.
In this setup, Amazon doesn’t need to own Anthropic to win. It just needs Claude to remain committed to its Trainium chips and AWS platform. That gives Amazon recurring, scalable, high-margin revenue from one of the fastest-growing sectors in tech—all while avoiding the regulatory scrutiny that might come with owning the company outright.
Advertising Synergies & AI Tailwinds
Amazon’s advertising business—already $15.7 billion a quarter—is the sleeper hit here. AI isn’t just about chatbots or code completion. It’s also about targeted advertising, content recommendation, and product placement, all of which Claude and Nova can help improve. The data Amazon has across retail, Prime Video, Twitch, and Fire TV is gold dust for AI models that learn user preferences and behavior.
Anthropic’s models can supercharge these insights. And with Amazon DSP integrating with Roku and Disney+ ad inventories, the company is laying the groundwork to make every touchpoint smarter, faster, and more monetizable. AI doesn’t just cut costs—it boosts the top line, especially when paired with Amazon’s proprietary signals and real-time transaction data.
Advertising is already Amazon’s highest-margin business—likely north of 30%—and generative AI can help widen that margin even further. While Google and Meta dominate traditional digital ads, Amazon’s ability to tie AI directly to transaction intent could give it an edge that’s hard to replicate.
The Google Risk & Cloud Turf War
Here’s the wrinkle: despite Amazon’s $8 billion investment, Anthropic is also talking to Google. That deal could be worth tens of billions, and it’s not hard to see why. Google has its own powerful AI chips (TPUs), a growing cloud business, and deep roots in the AI research community. If Anthropic ends up leaning more heavily on Google Cloud, it could dilute AWS’s position as the “primary partner.”
Even worse, it could undermine Amazon’s pitch that its Trainium chips are the go-to solution for training cutting-edge models. There’s also reputational risk. If Google ends up with the bigger chunk of Claude’s training and inference workloads, analysts might question Amazon’s ability to hold onto its marquee AI client—and by extension, its AI credibility.
It’s a tough balancing act. Anthropic, like OpenAI before it, will likely remain multi-cloud for strategic reasons. But if Google’s involvement deepens, Amazon could lose out on some of the long-term growth it’s banking on. That would put more pressure on in-house tools like Bedrock and Nova to pick up the slack.
Final Thoughts: A Partnership That’s Working, But Not Exclusive
Amazon’s evolving relationship with Anthropic is a microcosm of the broader cloud wars. It shows the promise of AWS’s full-stack AI approach—from chips to models to infrastructure—but also highlights the risks of relying on partnerships that can shift.
The bullish view is clear: Anthropic is using AWS more deeply than ever, including for training Claude models on Trainium2 and deploying via Bedrock. The stickiness of that setup is real, and the synergies with Amazon’s broader ecosystem—from Alexa to Ads—only deepen the moat. Meanwhile, AWS continues to generate over $123 billion in annual revenue and accounts for the majority of Amazon’s operating income.
But there are real headwinds. Google is muscling in. Anthropic is hedging its bets. And the competitive dynamics in AI cloud are shifting fast.
From a valuation perspective, Amazon trades at 17.9x LTM EV/EBITDA and 31.4x LTM EV/EBIT—relatively high but not outrageous for a business with a wide moat, double-digit revenue growth, and dominant positions in three secular megatrends: cloud, AI, and digital advertising. With the stock recently trading around $218 and a fair value of $245, it’s priced at roughly an 11% discount—modest, but not screamingly cheap.
In short: Amazon’s bet on Anthropic is still playing out. It’s a high-upside, medium-risk move in a game that’s far from over.
