What is that spend compared against though? They already spend hundreds of billions of on various things in a year, but what is the marginal spend?

When you present these numbers alongside each other, you imply that they will go from making ~$20b/quarter to losing ~$30b/quarter, which is not plausible to me.

Yes 100B in capex is unprecedented for Amazon (let alone 200). Last time they peaked Capex was at ~60B in 2021 when they decided to double their supply chain network.

So the marginal capex on gpus is likely 70-80% of their total capex
