Sergey Brin has an estimated net worth of $257 billion, according to Forbes Real-Time Billionaires, Sergey Brin profile (figures as of October 20, 2026). That is up from $49.8 billion in 2019.

Sergey Brin is a computer scientist and businessman best known for cofounding Google with Larry Page. The 2 met at Stanford University while studying computer science and built an early web search engine together. In 1998, they launched Google. The project grew from a campus tool into a major internet company. Google went public in 2004, and in 2015 it began trading under Alphabet, the new parent company.

Brin built his fortune through Google, which Forbes places in the technology industry. He served as president of Alphabet until stepping down in 2019. He still holds major influence there as a board member and controlling shareholder, alongside Page. In 2023, he returned to help with AI research at Alphabet. Forbes says his net worth was $257 billion on its real-time billionaires tracker as of October 20, 2026.

How Sergey Brin built his wealth

Most of Brin's wealth comes from Google, the company he started in 1998 with Larry Page after they met at Stanford. Their search engine became popular at the university, and they left their PhD path to build the business. When Google went public in 2004, Brin's ownership stake became far more valuable. In 2015, the company began trading as Alphabet, with Brin and Page staying on as cofounders, controlling shareholders, and board members.

His money remains tied closely to Alphabet because he is still a controlling shareholder and board member, even after leaving the president role in 2019. That means his fortune rises and falls with the company behind Google. Brin also backed other projects named in the facts, including Space Adventures in 2008 and LTA Research & Exploration LLC. Still, the main engine of his wealth is his long-held stake in the Google and Alphabet business.

Forbes net worth timeline

Forbes has shown large swings in Brin's fortune over time. It estimated him at $49.8 billion in 2019, then $49.1 billion in 2020. The number jumped to $89 billion in 2021 and $107 billion in 2022 before dropping to $76 billion in 2023. Those moves fit the fact that Brin's wealth is centered on Alphabet, so changes in the value of that company have an outsized effect on his personal fortune.

After that dip, Forbes put Brin at $110 billion in 2024 and $138 billion in 2025. On Forbes' real-time billionaires tracker, he reached $257 billion in October 2026. That rapid climb again points back to the same source: his continued stake in Alphabet and his status as a controlling shareholder. Even after stepping down from day-to-day leadership in 2019, his financial position stayed closely linked to the company he helped create.
