Mark Attanasio Net Worth

Mark Attanasio has an estimated net worth of $1.9 billion, according to Forbes Real-Time Billionaires, Mark Attanasio profile (figures as of October 20, 2026).

Mark Attanasio is an American investor best known as the chairman and principal owner of the Milwaukee Brewers. He also became the majority shareholder of Norwich City FC. His career started in law, but he moved into finance in the mid 1980s when he joined Drexel Burnham Lambert, an investment bank known for junk-bond trading. That shift set up the work that made him wealthy and raised his profile in both finance and sports.

His biggest business move came in 1991, when he cofounded Crescent Capital Group in Los Angeles. The firm focuses on debt investing and now manages $43 billion in assets. Attanasio later expanded into sports ownership. In 2004, he bought an estimated 45% stake in the Brewers for a reported $220 million, then added more sports exposure through Norwich City and Strategic Sports Group, which in 2024 agreed to invest $3 billion in the PGA golf tour.

How Mark Attanasio built his wealth

Most of Attanasio’s fortune comes from finance. After working as a lawyer, he joined Drexel Burnham Lambert in the mid 1980s and moved into investment banking. In 1991, he cofounded Crescent Capital Group, a Los Angeles-based investment firm focused on debt. That business became the center of his career. Forbes places him in Finance & Investments, and Crescent now has $43 billion in assets under management.

Sports ownership is another major part of his business story. Attanasio bought an estimated 45% stake in the Milwaukee Brewers in 2004 for a reported $220 million and became the team’s chairman and principal owner. Forbes now values the Brewers at $1.6 billion. He also became the majority shareholder of Norwich City FC and invested in Strategic Sports Group, whose 2024 agreement brought $3 billion into the PGA golf tour.

Forbes net worth and money picture

Forbes estimates Mark Attanasio’s net worth at $1.9 billion on its real-time billionaires tracker as of October 20, 2026. Forbes also put him at $1.9 billion on the World’s Billionaires lists for 2025 and 2026. That steady estimate points to a fortune tied to long-term assets rather than one short burst, with finance as the main engine and sports holdings adding another important layer.

The shape of his wealth is fairly clear from his holdings. Crescent Capital Group remains the core financial asset, while the Brewers add a high-profile team investment that Forbes values at $1.6 billion. His portfolio also includes Norwich City FC and Strategic Sports Group. Together, those pieces help explain why Forbes has kept its estimate at $1.9 billion across its recent annual lists and real-time tracker.
