The Milwaukee Brewers are a Major League Baseball (MLB) franchise based in Milwaukee, Wisconsin, United States. They compete in the National League’s Central Division. Their home ballpark is American Family Field (formerly Miller Park).
Since 2005, the team has been led by Mark L. Attanasio, who serves as chairman and principal owner. Under Attanasio’s ownership, the Brewers have had significant on-field success, with competitive records and multiple postseason appearances.
Ownership Status of the Milwaukee Brewers
Principal Owner & Majority Stake
Mark Attanasio is the principal owner and chairman of the Brewers. He purchased the franchise in 2004 (closing in early 2005) from Wendy Selig-Prieb, then the controlling owner.
When he acquired the team, his stake was estimated to be about 45 % of the franchise.
Though Attanasio is the public face and holds the largest stake, the Brewers operate with a group ownership structure that includes multiple minority shareholders.
Minority Owners & Stakeholders
- John A. Canning Jr. is a known minority owner.
- Reports indicate that the 2005 ownership purchase included several holdovers from the previous ownership, such as John Canning Jr., Stephen Marcus, Harris Turer, and David Uihlein Jr.
- In 2021, NBA star Giannis Antetokounmpo joined the Brewers’ ownership group by purchasing an undisclosed stake.
- In late 2023, it was reported that Ralph and Shelly Stayer, owners of Johnsonville LLC, joined as minority owners.
Thus, while Attanasio is the major owner, ownership is shared among a group of investors and stakeholders.
Recent Developments & Valuation
According to Forbes, the Brewers’ valuation in March 2025 was around US $1.7 billion, and Attanasio remains listed as the owner.
Attanasio has been involved in securing legislative and financial support to ensure the team remains in Milwaukee through at least 2050, via stadium and lease negotiations.
