Jerry Reinsdorf is the principal owner and chairman of the Chicago White Sox, a position he has held since 1981.
Reinsdorf led an investment group that bought the club for nineteen million dollars, one of the most lopsided sports deals of the twentieth century when you compare that price to today.
He personally owns roughly nineteen percent of the franchise outright, but four decades of control and board influence have made him synonymous with White Sox ownership.
The team is now valued at close to two billion dollars by Forbes, even after a rare year over year dip in that number for 2026.
In June 2025 Reinsdorf agreed to a long range framework that will eventually hand controlling interest of the club to Chicago billionaire Justin Ishbia.
Ishbia has already begun making capital contributions as a minority owner, while Reinsdorf keeps full decision making authority in the meantime.
The handoff is not fast. Reinsdorf can choose to sell controlling interest anywhere between 2029 and 2033, and Ishbia gains the right to force a deal after the 2034 season.
That slow timeline stands next to a rough stretch on the field. The 2024 White Sox lost 121 games, the most losses by any team in modern MLB history, per ESPN.
Fans on the South Side have been openly frustrated with Reinsdorf for years, questioning why a 90 year old owner still controls major franchise decisions.
So why would a billionaire in his ninetieth year sign off on a sale that might not fully close until 2034? The answer involves tax planning, family legacy, and a genuine belief that the rebuild underway in 2026 is finally working.

Chicago White Sox Ownership History
The team traces back to 1900, when Charles Comiskey moved his Sioux City club to Chicago, a full history detailed on Wikipedia.
Charles Comiskey relocates his team to Chicago and later joins the American League in 1901.
Eight players are banned for life after conspiring with gamblers to fix the World Series.
Veeck buys majority control and leads the club to its first World Series appearance since 1919.
Jerry Reinsdorf and Eddie Einhorn purchase the White Sox for 19 million dollars.
The White Sox win their first title since 1917, sweeping the Houston Astros.
The club loses 121 games, the most losses in modern MLB history.
Reinsdorf agrees to a framework that eventually transfers controlling interest to Justin Ishbia.
How Much Did Jerry Reinsdorf Pay For The White Sox In 1981
Reinsdorf and business partner Eddie Einhorn led an investment group that purchased the Chicago White Sox in 1981 for 19 million dollars, according to Forbes.
At the time that price was considered a serious sum for a struggling American League club that had not won a title since 1917.
Reinsdorf had already built his fortune in real estate after cofounding the Balcor Company in 1973 and selling it to American Express nine years later.
That capital allowed him to move quickly into sports ownership, and just four years later he also bought into the Chicago Bulls.
Measured against the 1.94 billion dollar valuation Forbes now places on the White Sox, the original 19 million dollar purchase has grown by more than one hundred times over.
Is Jerry Reinsdorf A Good Owner: Is White Sox Ownership Really Worth It
Reinsdorf’s record as White Sox owner is genuinely mixed, and that split shows up clearly when you weigh the highlights against the lowlights.
On the positive side, he delivered a World Series championship in 2005, ending an 88 year title drought for the franchise.
Financially the investment has been a massive success, turning a 19 million dollar purchase into a franchise worth nearly two billion dollars.
On the negative side, the team endured a historically bad 2024 season, losing 121 games, and payroll spending has drawn steady criticism from fans and analysts alike.
Many South Side supporters argue that Reinsdorf prioritized profit margins over on field competitiveness for much of the 2010s and early 2020s.
The 2026 roster under general manager Chris Getz has shown real improvement, giving some fans hope the rebuild is finally paying off.
Verdict: a financially brilliant owner whose competitive record leaves plenty to be desired.
How Much Are The Chicago White Sox Worth In 2026
Forbes valued the Chicago White Sox at 1.94 billion dollars in its March 2026 rankings, as shown on the Forbes team page.
That figure represents a small three percent decline from the prior year, a rare dip among MLB franchises that have mostly climbed in value.
Team revenue stands at roughly 239 million dollars, with operating income reported at a loss of about 40 million dollars.
Despite the recent dip, the franchise has appreciated more than 800 percent since Forbes began tracking MLB valuations in 1998.
What Is Jerry Reinsdorf’s Net Worth In 2026
Forbes places Jerry Reinsdorf’s net worth at 2.3 billion dollars as of August 2026.
Beyond the White Sox, Reinsdorf also owns a large stake in the Chicago Bulls, the NBA team he bought into back in 1985 for 9.2 million dollars.
The Bulls are now worth roughly 5 billion dollars, and Reinsdorf’s estimated 40 percent stake makes that franchise the larger share of his sports wealth.
His fortune traces back to real estate, a law degree from Northwestern, and an early career as a tax attorney with the IRS before he moved into business.
Rate Field And The South Side Stadium Question
The White Sox have played at Rate Field, formerly known as Guaranteed Rate Field and U.S. Cellular Field, since it opened in 1991.
The ballpark replaced the original Comiskey Park, a stadium named after founder Charles Comiskey that stood across the street for more than 80 years.
Rate Field has faced criticism over the years for its atmosphere compared to newer parks, and stadium upgrades remain a recurring topic in Chicago sports coverage, a subject touched on in our look at how MLB equipment gets made.
With Justin Ishbia’s future involvement, some analysts expect renewed investment in the stadium and player facilities once the ownership transition advances.
Is The Chicago White Sox For Sale In 2026
The White Sox are not fully for sale in 2026, but the club has already begun a structured, multi year transition toward new ownership.
Justin Ishbia is investing as a minority owner now, with the option for Reinsdorf to sell controlling interest between 2029 and 2033.
If no deal happens by then, Ishbia can force a transaction after the 2034 season, guaranteeing the franchise eventually changes hands.
It is a slower version of ownership change seen elsewhere in professional sports, a pattern similar to succession plans discussed in our breakdown of NFL ownership structures.
