Alphabet Inc. is primarily owned by institutional investors and the company's co-founders. The largest shareholders include The Vanguard Group (7.25%), BlackRock (6.27%), and State Street Corporation (3.36%). Founders Larry Page and Sergey Brin each individually own about 3% of the company’s shares but maintain majority voting control through special Class B shares that carry 10 votes each. This share structure gives them about 51% of the voting power, allowing them to direct Alphabet's long-term strategy despite owning a smaller percentage of the total shares. Other institutional investors like Fidelity Investments and Capital International Investors also hold significant stakes. In summary, Alphabet's ownership is a mix of large institutional investors holding most of the equity shares and the founders holding smaller equity stakes but controlling majority voting power due to the unique multi-class stock structure.
