SoftBank's Masa Son

Uber's single largest shareholder isn't the company's founder or even the venture capital firm that was Uber's earliest investor.

SoftBank , Masa Son's tech conglomerate, is Uber's biggest shareholder . SoftBank amassed a 16.3% stake in the company since December 2017.

But other people and companies will be worth a lot of money when Uber goes public.

-- Matt Cohler, the head of Venture Capital firm Benchmark, owns 11% of the company

-- Travis Kalanick, Uber's founder, owns 8.6%

-- Garrett Camp, head of tech consultancy Expa, owns 6%

-- The Saudi Public Investment Fund owns 5.3%

-- Alphabet, Google's parent company, owns 5.2%

-- Ryan Graves, Uber's CEO in 2010, owns 2.4%
