These people can personally borrow large amounts at such low interest that it’s effectively cash (if not 0% altogether) because a bank will value its relationship to these people that high (because they’re probably also the corporate bank for these companies).
I also think you’re extremely underestimating just how big these companies are. Jeff is liquidating ~1 billion a year just to fund his space company. Zuckerberg sold $280 million in 1 month in 2020 for walking around money.
No they can’t liquidate their entire position. They do have effectively almost unlimited financial reserves through multiple different channels. Said another way, they have $10s of billions in buying power even if they can’t access that entire wealth instantly as cash.
