Ah the majority shareholder question rears it’s head again.
The real issue is the fact the Market Cap is nowhere near what would be needed to have a controlling share of ATVI. Market cap is equal to the share price X the number of outstanding shares.
Market Cap is currently $35.56 billion while my estimate for a controlling share of ATVI is $57 billion (aka %51 of all shares). Meaning that at some stage you would need to convince those who have the shares you need to sell back to.
