Seriously though, what are the odds that someone has been quietly spending 10s/100s of millions in cloud compute to brute force the keys for old wallets?

There are 200 million+ BTC wallets.
They've found 54 out of 200 million+ or about 0.00002% of wallets - in how many years?
Especially now with AI, I wouldn't be surprised if an amateur kicked a bunch of tires and got lucky.
Just because they are not published, does not mean they are not using them, someone else found them and are using them. Or they just have the keys from back in the day.
Can't wait to follow this story as it unfolds. The other risk is Quantum... That is going to be real fun when it starts making leaps above Moores Law.
There needs to be a industry wide effort NOW! That researches and generates keys in unconventional ways, different than the ways they are being generated now. Because Quantum is a beast. Those keys will need to be Quantum proof, which means that even if the agent knows the algorithm that is used to generate the keys they cannot duplicate the keys that were generated the first instance it was run. Or you can start doing Hashing across fingerprint, eye and dna data. That is coming my folks!
This is common practice in the stock market, called "dark pools" [0]

So if you had 10,000 H100s running, it'd only take ~1500 years.
You'd have a high probability to find key in under ~1000 years, though.
Even if I'm off by 3 orders of magnitude, it would take a decade and cost billions, and not make financial sense.
While ~$8B is huge news, due to the potential that all ~$188B might be in play, when most investors probably expected it was not prior to this - or at least the probability was low enough to barely factor, it's unlikely to crash BTC.
Further, moving BTC is one thing. Showing signs of liquidation is another.
That much should be able to get liquidated intelligently without moving the market.
Even if you do, there could in theory still be a way to narrow down the key space or find some other shortcut to a wallet key, even if nobody has figured it out yet.
It’s not just the printing of transaction price that can affect the market.
BTC private key space is 256 bit. Let's say a billion wallets, that's 30 bits, so you need to check 226 bits to hit one wallet.
A H100 does about 1000 TFLOPS at the very most, that's 10^15 or 50 bits per second (generously assuming we can check on key per FLOP).
6B days of that will give you an additional 50 bits (6 = 8 = 3 bits, B = 1000^3 = 30 bits, day = 10^5 seconds = 17 bits).
Now we're talking 100 bits. But as discussed above, you need to check 220 bits to hit a key. There's still quite a gap.
For comparison, the entire Bitcoin network (using 1% of world electricity) does about 1000 EH/s at the moment, that's 10^21 or 70 bits per second (so, roughly equivalent to a million of H100, using the rough overestimating sketch above).
Per year, that's 70+25 = 95 bits. Still far.
As someone once said, I can explain it to you, but I can't understand it for you.
