## The AI risk debate hit stocks
Monday was the day Wall Street finally traded on the existential-risk argument. The reaction was not a blanket sell-off, and that is the interesting part.

> New York and San Francisco finally connected on Monday
## Chipmakers took the hit
Nvidia fell more than 3%. Intel, AMD, and Marvell dropped 5% to 6%, pulling the Philadelphia Semiconductor Index down almost 6%. Neoclouds sank too.
## The buyers went up
Alphabet rose almost 2%, Microsoft added 1.6%, Meta gained about 1.4%. Amazon slipped 1.6% but held far better than the chip names.
## What sparked it
On Saturday, Anthropic CEO Dario Amodei called for stronger safety measures and a slowdown in model development after alarming demos of models' cyber abilities. Sam Altman and others backed him.
## Picks and shovels lose first
D.A. Davidson's Gil Luria says a slowdown guts infrastructure sellers like Nvidia and CoreWeave. Hyperscalers would just stop building and harvest what they already own, sending cash flow up as capex falls.

> They'll just all stop building data centers and just digest what they have
## Maybe nobody is slowing
Luria notes no lab has announced an actual training moratorium. Dan Ives adds that China is not pausing, with Z.AI raising $5 billion over the weekend. Oil above $108 and a 5% 10-year yield did the rest.

> Until they say that, they're not actually slowing down
## Key takeaway

If the frontier race slows, the companies selling picks and shovels bleed first, while the buyers can stop spending and bank the cash.
