Facebook doesn't get the money when you buy a share of META -- that goes to the person you bought the share from. They could do an offering to raise money, but they aren't. They've been doing the opposite, they've been buying back shares at a significant rate. Some of it is to offset stock based compensation, and some of it is just stock pumping.
The high share prices do subsidize Meta's share-based compensation, which seems to make up a substantial portion of the total wage bill. High and rising share prices also allow Meta to purchase other companies with Meta shares, instead of having to pay cash, which is beneficial in many ways.
> Facebook doesn't get the money when you buy a share of META
Technically no, but in reality yes, because shares are used as currency.
For instance, META does not acquire companies using cash, they use their own shares as payment. The higher the stock price, the lower the dilution.
Same thing for stock options and RSU.
So, it's true that stock prices don't translate 1:1 to cash inflows, but wherever stocks are currency (employee compensation, benefits, acquisitions, etc), it does translate.
