Glenn Dubin Net Worth

Glenn Dubin has an estimated net worth of $2.9 billion, according to Forbes Real-Time Billionaires, Glenn Dubin profile (figures as of October 20, 2026). That is up from $2 billion in 2019.

Glenn Dubin is an American investor known for building hedge funds and private investment firms. He started in finance at E. F. Hutton in 1978 after playing football at Stony Brook University. In 1984, he and Henry Swieca launched Dubin & Swieca Capital Management, an early fund of funds business. He later became best known as a cofounder of Highbridge Capital Management, a major multi-strategy hedge fund started in 1992.

His wealth comes mainly from hedge funds, later sales, and stakes in other investment businesses. In 2004, JPMorgan bought a majority stake in Highbridge for $1.3 billion. Dubin also founded Engineers Gate, a quantitative trading firm, and became lead shareholder of Castleton Commodities after an investor group bought the energy business in 2012. He now runs Dubin & Co., a family office that invests in growth companies including Brex and Scale AI.

How Glenn Dubin built his fortune

Dubin’s career took shape in finance over several decades. After working as a stock broker at E. F. Hutton, he cofounded Dubin & Swieca Capital Management in 1984. That firm focused on multi-manager hedge fund portfolios. His biggest career move came in 1992, when he and Henry Swieca launched Highbridge Capital Management. Highbridge grew into a major alternative asset manager and became the core of the fortune that later made him a billionaire.

A major turning point came in 2004, when JPMorgan bought a majority interest in Highbridge for $1.3 billion. Dubin stayed active in investing after that deal. In 2012, he joined an investor group that bought an energy business later known as Castleton Commodities, where he became lead shareholder. In 2013, he founded Engineers Gate, a quantitative hedge fund. He later shifted his focus to Dubin & Co., which backs private growth companies such as Brex and Scale AI.

Forbes net worth over time

Forbes estimated Dubin’s net worth at $2 billion in 2019, and kept that same figure in 2020, 2021, and 2022. That stretch points to a period of relative stability in the value of his holdings. By then, his money was tied to a mix of hedge fund wealth, private investments, and his stake in Castleton Commodities, rather than only the earlier Highbridge business that helped establish his fortune.

The Forbes estimate then moved higher, reaching $2.7 billion in 2023 and $2.9 billion in 2024. Forbes still had him at $2.9 billion on its real-time billionaires tracker as of October 20, 2026. His current wealth is linked to finance and investments, with backing for early and late-stage companies through Dubin & Co. adding another layer alongside his hedge fund background and energy holdings.
