Not really, I sort of just ballparked it (pulled it out of my ass) based on the available numbers you can get from some vendors like Digikey, or Arrow. Go search out the UltraScale+ Virtex devices there, in individual quantities, and they'll range in the $20k space easily at the higher end.[1]
These particular cards seem to be otherwise unobtainable and the series isn't exactly listed anywhere I can see. They're clearly at the high end, close to those listed ones, though.
Plus, and someone correct me, because I could be very, very wrong -- those $20k numbers are only for the literal chips you get, I think, not counting the actual necessary "surrounding" device. You get surface mounts. So the actual connecting fabric and everything is going to drive the price up even higher.
That said, I doubt Amazon is obviously paying $30-40k a device... I bet they get absurd margins at these rates. Just the lowly individual purchasers would pay that price. (Aside from just literally buying in huge quantity, there's probably some element where they can say "We are Amazon, give us deals.")
