The News

Alphabet closed last week with a market cap of $4.8 trillion, behind only Nvidia at $5.2 trillion . The driver: a report that AI model developer Anthropic committed to spend $200 billion on Google Cloud over five years for 5 gigawatts of compute . Oren Luria noted that Google "told us their backlog roughly doubled without telling us that almost the entire increase came from one deal with Anthropic" , echoing how Oracle was punished after investors realized a major share of its backlog growth was tied to OpenAI, with the stock losing about half its value over five months . Mizuho estimates roughly $61 billion of Google's cloud backlog through 2027 could come from sales of its TPUs .

The Read

The market is rewarding Alphabet for two things investors couldn't price last year: TPUs as a real Nvidia alternative, and customer concentration risk being temporarily a feature (one whale signs, the stock pops). But the Oracle comparison is the one to watch — concentration cuts both ways, and Anthropic is now a top customer at Google Cloud, AWS, and (via Colossus) what used to be xAI. When the same hyperscaler is selling TPUs to the same lab whose product competes with Gemini, the strategy is no longer "win AI"; it's "be the toll booth regardless of who wins."

Watch For

Whether Google discloses Anthropic's share of its cloud backlog on the next earnings call. If it doesn't, you are watching the Oracle playbook in real time and should baseline your own exposure now: list every AI-cloud vendor in your stack, and mark which ones have a single named customer driving more than 20% of their disclosed growth. That sheet is your supply-chain risk register for Q3.
