Tech giants are shifting from solely providing computing power to distributing AI models, unlocking a lucrative new revenue stream
Cloud platforms like AWS Bedrock and Microsoft Azure are seeing a wave of interest as buyers look for vendor-agnostic systems to deploy custom AI tools.
Alphabet, Amazon.com and Microsoft have become some of the largest companies in the world. And one analyst thinks the party is just getting started as these hyperscalers expand their growth beyond artificial-intelligence data centers.
As enterprises race to adopt AI, Alphabet (GOOGL) (GOOG), Amazon (AMZN) and Microsoft (MSFT) are &#34;quietly shifting from being providers of AI compute capacity to becoming AI model and product-distribution hubs for OpenAI and Anthropic to scale in the enterprise,&#34; UBS analyst Karl Keirstead wrote in a Wednesday note.
For example, Amazon has been steadily strengthening its partnership with Anthropic, investing $5 billion in the Claude creator in April. Anthropic has agreed to spend more than $100 billion on Amazon Web Services over the next decade, and AWS customers can now access the Claude platform directly without additional contracts or billing relationships.
The medium-term &#34;upside in terms of revenue growth from this broadening-out of AI revenue sources is underappreciated by [Wall] Street and could drive [revenue] estimates and the stocks higher,&#34; Keirstead added.
The hyperscalers' beneficial relationships with OpenAI and Anthropic could already be seen this earnings season in their explosive cloud and backlog growth.
&#34;It is abundantly clear to investors that the hyperscalers are getting a massive boost from compute-hungry model providers,&#34; Keirstead wrote.
Amazon, Alphabet and Microsoft are also quickly converting their contracts into revenue, giving investors more confidence in the stability of their cloud businesses. Alphabet expects to recognize over 50% of its backlog in the next two years, resulting in $231 billion of expected Google Cloud revenue. For context, Google Cloud's current annual run rate is $80 billion, meaning that Google Cloud growth for 2026 and 2027 should be &#34;very strong,&#34; according to Keirstead.

AI revenue in particular experienced strong growth in the first quarter of 2026. Microsoft reported total annualized AI revenue of $37 billion, and UBS estimates that around $33 billion of that comes from Azure. Annualized AWS AI revenues surpassed $15 billion, and Google's enterprise AI revenue grew 800% year over year. Azure's growth &#34;strongly hints to us that Microsoft is benefiting substantially from its material exposure to OpenAI,&#34; Keirstead wrote.
These cloud revenues aren't just coming from bringing new data-center capacity online, Keirstead believes. Big Tech companies are also becoming distribution platforms for AI models. Platforms like AWS Bedrock, Microsoft Foundry and Google Vertex allow enterprises to access models of their choice and build custom AI agents instead of acquiring them from third-party software providers.
According to UBS's industry checks, enterprise AI budgets are shifting toward hyperscalers because customers want the flexibility of a third-party platform to try different models.
Additionally, while Anthropic and OpenAI do sell their products directly to enterprises, they're often utilizing AWS and Azure to distribute their offerings. &#34;Many large organizations will end up accessing AI coding agents as well as many other [first-party] products of Anthropic and OpenAI through their existing commercial relationships with AWS and Microsoft Azure,&#34; Keirstead predicted.
The hyperscalers' valuations &#34;have by no means peaked,&#34; in Keirstead's opinion. Microsoft trades at 22.5x forward earnings, Amazon trades at 27.1x and Alphabet trades at 25.2x - levels that Keirstead believes are not pricing in the hyperscalers' growing AI opportunities.

UBS analyst Karl Keirstead argues that Amazon, Microsoft, and Google are shifting from AI compute providers to model distribution hubs, a trend Wall Street underappreciates. This strategic pivot unlocks lucrative revenue streams through partnerships with OpenAI and Anthropic, driving strong cloud growth. With significant backlogs converting to revenue and expanding AI budgets favoring hyperscaler platforms, Keirstead believes current valuations do not reflect these growing opportunities.

- Tech giants like Alphabet, Amazon, and Microsoft are transitioning from providing computing power to acting as distribution hubs for AI models, creating new revenue sources.  
- Analysts emphasize that the cloud platforms are seeing increased enterprise interest due to the flexibility of deploying custom AI tools, with notable partnerships like Amazon’s $5 billion investment in Anthropic.  
- As these companies convert contracts into revenue, significant growth in AI revenue is anticipated, with Microsoft’s AI revenue hitting $37 billion annually, potentially driving stock prices and revenue estimates higher.
