Anthropic closed a reported $65 billion Series H this week at a $965 billion post-money valuation, nudging past the $852 billion mark OpenAI set in its March round and reordering the top of the AI-lab table. Apollo and Blackstone are reportedly shopping a roughly $36 billion private-credit deal to buy Google chips that Anthropic would lease. The quieter story is defense AI absorbing nearly half of all venture dollars in a single recent week.

In the last two weeks, NextEra agreed to buy Dominion Energy for $67 billion to feed data center power demand. Anthropic signed a deal to pay xAI $1.25 billion per month for compute. CoreWeave doubled Q1 revenue but carries $25 billion in debt at 11% interest. And the hyperscalers collectively guided to $725 billion in 2026 capex. Everyone is building as fast as they can — but the demand forecasts justifying all of it rest on assumptions that Goldman Sachs says can swing by hundreds of billions with a single variable change. Today's thesis: the data center capex chain, who's exposed, and what breaks if the projections are wrong.
