Napkin math on 5 year depreciation is 5.5 billion per year for 28 billion. However the 28 billion is cash upfront, spacex is probably paying 10-20% interest on the 28 billion for another 2-6 billion per year.

So net you are looking at finance expenses of 7-11 billion per year. The electricity costs will be significant on top of that, but harder to get a solid read on.

Net of everything, spacex may be getting a 14-28 percent yield before paying for electricity. After electricity/insurance/data/taxes/other expenses - I’d guess it’s anywhere between 0% and 7% yield.

Odds are good that Anthropic abandons the deal before the depreciation schedule completes. Who is going to rent the GPUs then?
