I doubt it too. And, if they were planning something like that, they wouldn't do it when everyone is expecting it.

While we are speculating here, let me throw in my 2 sats: No one can buy 1 million whole bitcoin for $43 Billion in one fell swoop. Back of the envelope computation says they would be lucky to get 400k BTC for this price, and a buy of this size will trigger a new ATH breaking $100k. But buying spot at this level reeks of desperation. There are other, including sinister, ways to accumulate that kind of coinage: Force MSTR and GBTC to loosen their coins somehow. Scare hodlers into selling with some serious 6102 level FUD. Get Coinbase to go fractional. Use the futures market. Buy miners and build hashrate. Perhaps all of the above. Bottom line. Stay humble and stack.
