If you're talking about dodgy accounting at hyperscalers, a larger worry might be that they are overstating profits by depreciating their assets (such as datacenters and CPUs/GPUs) too slowly.
Estimates are that this could overstate profits by tens of percent. (However, this only allows earnings to be "pulled forward" - sooner or later the servers must be written off and the accounting catches up.)
Is this true? The best data I could find is that A100 costs are decreasing slightly, H100's have been holding steady and B-series have been increasing?
If anything those GPUs should not be marked down at all.
Burry is wrong.
