# Alphabet Co-Founder Sergey Brin Has Sold $25.3 Billion in GOOG Stock Across 10,633 Transactions

> Sergey Brin, co-founder and director of Alphabet, has filed 10,633 insider transactions totaling $25.3 billion in sales — the largest insider sell total in the tech sector.

Sergey Brin, co-founder and director of Alphabet Inc. (GOOG), has sold $25.3 billion in company stock across 10,633 insider transactions — one of the largest insider sell totals of any individual in tech history. Despite two decades of selling, Brin still holds over 359 million shares worth approximately $60 billion at current prices. His most recent filing from February 2026 was a gift of 437,500 shares, not a sale. The Numbers Metric Value Career Sell Value $25.3 billion Career Buy Value $254K Total Transactions 10,633 Last Filing Feb 19, 2026 Shares Remaining 359.8 million What It Means Brin's $25.3 billion in career sales represents steady diversification from the company he co-founded in 1998. His selling has been entirely through pre-arranged 10b5-1 plans, with the last actual sales occurring in April 2022 at pre-split prices around $2,600 per share. Since then, his filings have consisted exclusively of stock conversions (Class B to Class A) and charitable gifts — suggesting his 10b5-1 selling plan may have been paused or terminated. Even after $25 billion in sales, Brin remains Alphabet's second-largest individual shareholder behind Larry Page. His 359+ million shares represent significant voting power through the dual-class stock structure. The shift from selling to gifting aligns with Brin's increased philanthropic activity through the Brin Wojcicki Foundation. What to Watch Whether Brin resumes direct sales through a new 10b5-1 plan after a 3+ year pause, which would be a major signal given the share price has nearly tripled since his last sale The pace of charitable gifting, which has averaged millions of shares per quarter and serves as an alternative form of position reduction Any changes in Alphabet's dual-class structure that could affect Brin's voting influence relative to his economic interest
