What changed
DeepSeek at $80B is not just a model win. It's a pre-IPO asset. If it lists, China AI gets a public valuation anchor the whole sector trades against.
OpenAI's Crazy 28 Days Day One: whatever it shipped, the China read-through is release speed. If OpenAI ships daily, Chinese labs can't do quarterly. Expect a same-week counterpunch.
A solo Physics Nobel is rare. One winner means one specific breakthrough, not a committee. If it's AI-adjacent hardware, it's a chip and compute story.
What it adds up to: DeepSeek has $80B and an IPO clock. OpenAI is in a 28-day sprint. Terence Tao turning cautious is the policy tell. Money still leads, but regulation is the next repricing event.
