Confidence rating:

The majority of Brin's fortune is derived from his stake in Alphabet, the parent company of Google, the world's largest search engine, according to Net Market Share. Google processes about 4.5 billion web searches daily, according to Smart Insights.

The billionaire owns both Class B and Class C shares, giving him an aggregate stake of about 5.5 percent of the business, according to a November 2017 filing. Brin's Class B shares don't trade and are valued using current market prices for the company's Class A shares. They're convertible into the publicly traded shares on a one-for-one basis, according to Google's 2017 proxy. The 2017 filing shows he also owns about 19 million shares of Alphabet Class C stock, which are also traded.

Since the company's 2004 initial offering, the billionaire has sold Google and Alphabet stock valued at about $9 billion, according to data compiled by Bloomberg. The value of his cash investments is based on an analysis of share sales, market performance, charitable giving and taxes. This net worth calculation uses an investment allocation favoring venture funds and clean technology, which is in line with the billionaire's public comments about his investments.

No response was received to requests for comment on Brin's net worth e-mailed to Google's press office.
