All week the question was who controls AI. Today it got three answers, and none of them is "the market." First: four days after the largest IPO in history, SpaceX agreed to acquire Anysphere — maker of the AI coding tool Cursor — for $60 billion in stock, folding a leading agentic coding product (reportedly ~$2B in annual recurring revenue) into the same house as xAI's Grok models and Colossus supercomputer. If your engineers live in Cursor, your core development tool now sits inside SpaceX and xAI — a vendor-concentration question worth asking out loud.

Second: Chinese lab DeepSeek closed its first external round, more than $7.4 billion at a valuation north of $50 billion, on mostly domestic capital and structured so founder Liang Wenfeng keeps full control. While Washington restricts who may use US models and Paris rips out US software, Beijing is funding a fully independent frontier champion — sovereignty expressed as a cap table.

Third: the US Department of Justice intervened in a Clean Air Act suit to argue that xAI should keep running the 57-plus unpermitted gas turbines powering its Memphis-area data center, because Grok supports Department of War operations — classifying one company's compute as critical national infrastructure worth overriding pollution law to protect. The durable lesson: power, not chips, is now the gating constraint on AI scale, and the politics of who gets to build and energize data centers is turning combative.
