Ken Kendrick owns the Arizona Diamondbacks. He has served as managing general partner since 2004 and is the largest individual shareholder in the club.
Kendrick was part of the original 1995 ownership group that brought Major League Baseball to Phoenix as an expansion franchise.
He does not hold a full majority of the team by himself. Instead, he leads a wider group of investors that now includes billionaire Rob Walton.
The Diamondbacks are now worth close to two billion dollars, according to Forbes 2026 team valuations, a huge jump from the club’s expansion era price tag.
So how did a software entrepreneur from West Virginia end up running one of baseball’s most storied expansion teams, and why did one of the richest families in America quietly buy in two years ago without anyone noticing? The full story involves a boardroom fight, a threatened move out of state, and a stadium deal that took nearly a decade to finish.

Who Owns The Arizona Diamondbacks In 2026
Ken Kendrick is the man in charge of the Arizona Diamondbacks. His formal title is managing general partner, a role he has held since 2004, and he is widely described in team filings and press coverage as the largest shareholder.
Kendrick answers to a broader ownership group rather than acting as a lone owner. That group includes original investors from the team’s 1995 founding, plus newer minority partners such as Rob Walton, the Walmart heir who also owns the Denver Broncos.
Ownership control in Major League Baseball often works this way. A single managing partner runs the club day to day while a group of limited partners holds financial stakes without direct authority, a setup fans see across many professional sports leagues.
How Ken Kendrick Took Control Of The Arizona Diamondbacks Ownership Group
Kendrick built his fortune in software and banking. He earned a business degree from West Virginia University in 1965, worked at IBM, then founded the education technology company Datatel, which later became Ellucian and sold for 3.5 billion dollars in 2015.
When the Diamondbacks joined the league in 1995, Jerry Colangelo led the founding ownership group and Kendrick was one of several investors. Colangelo pushed hard to build a winning roster, and the strategy paid off with a World Series title in just the team’s fourth season, in 2001.
That championship run came at a cost. Heavy spending and deferred player payments left the club loaded with debt, and by 2004 the franchise was in financial trouble. Kendrick and a small group of partners committed roughly 160 million dollars over ten years to stabilize the team.
Forbes has valued the 2004 deal that gave Ken Kendrick operating control at roughly 238 million dollars. Once in charge, he restructured the organization and eliminated more than 350 million dollars in team debt over the following years.
Inside The Arizona Diamondbacks Ownership Structure And Investor Group
The Diamondbacks ownership structure is built around one controlling partner and several limited partners. Kendrick sits at the top as the point person for baseball operations and business decisions, while the rest of the group provides capital without day to day authority.

Several minority partners sued Kendrick in 2020 over disputes about financial disclosures and decision making power, a reminder that even inside one ownership group, priorities can clash. The case was a notable moment in franchise history and put a spotlight on how much authority a managing partner really holds.
Arizona Diamondbacks Ownership Timeline From 1995 Expansion To Today
The path from expansion franchise to today’s ownership group covers three decades of change, championships, and financial swings.

Arizona Governor Katie Hobbs signs a bill funding stadium repairs and keeping the team in Phoenix for thirty more years.
How Much Is The Arizona Diamondbacks Franchise Worth In 2026
The Diamondbacks entered the Forbes valuation list back in 1999 at just 291 million dollars. That number has grown enormously since then.
By 2026, the club’s Forbes valuation reached roughly 1.98 billion dollars, placing it in the bottom third of Major League Baseball franchises by value. Revenue sits around 324 million dollars, while operating income has been negative in recent seasons, a sign that on field spending and stadium costs have squeezed profits.
Even with those thin margins, the appreciation over almost thirty years has been massive. A team purchased into for a fraction of today’s price is now worth close to two billion dollars, which helps explain why families like the Waltons want a piece of it.
Why Rob Walton Bought Into The Arizona Diamondbacks Ownership Group
Rob Walton is a Walmart heir worth well over one hundred billion dollars. He already owns the Denver Broncos, which he purchased for 4.65 billion dollars in 2022.
Reporting from Sportico revealed that Walton quietly bought roughly a ten percent stake in the Diamondbacks around 2024, at a time when the franchise was valued near two billion dollars. The transaction was never publicly announced by the team.
Much of the money from that sale reportedly went toward Chase Field improvements, helping fund the stadium push that Kendrick had been fighting for since 2018. Walton remains a minority partner, and Kendrick continues to run the organization as managing general partner.
Chase Field And The Fight Over The Arizona Diamondbacks Stadium Future
Chase Field opened in 1996 and had never gone through a major renovation. By the early 2020s, the ballpark needed serious repairs, including an aging HVAC system and flood damage.
In early 2024, Kendrick publicly warned that the Diamondbacks could leave Arizona entirely if the state and county did not help fund the repairs. Negotiations with Maricopa County had already dragged on for years and grown tense at points.
The standoff ended in September 2025, when Arizona Governor Katie Hobbs signed House Bill 2704, securing the thirty year Chase Field agreement. The plan funds up to 500 million dollars in repairs using sales tax revenue generated at the ballpark, with the team committing at least 250 million dollars of its own money.
With funding locked in, talk of the Diamondbacks relocating out of Phoenix has largely quieted down, at least for now.
What The 2023 World Series Run Meant For Arizona Diamondbacks Ownership
Few people expected the Diamondbacks to reach the World Series in 2023. The team finished the regular season without a dominant record, then caught fire in October behind a young, athletic roster.
The playoff run gave Kendrick and the ownership group leverage they had not had in years. Renewed fan excitement and national attention strengthened the club’s case for public stadium funding, and many observers point to that momentum as a factor in the eventual Chase Field deal.
It also boosted the franchise’s profile heading into the current era of ownership, making the team a more attractive investment for a partner like Rob Walton.
Is Ken Kendrick A Good Owner: Is The Arizona Diamondbacks Ownership Really Worth It
Fans and analysts remain split on Kendrick’s record. There is a real case for both sides.
On the positive side, Kendrick eliminated more than 350 million dollars in franchise debt after taking control in 2004. Under his leadership the team has won two National League West division titles and reached two league championship series, plus a second World Series appearance in 2023. He also finally secured public funding for Chase Field after years of stalled talks, protecting the team’s future in Arizona.
On the negative side, three minority owners sued Kendrick in 2020 over how the franchise was being run and disclosed to partners. His 2024 threat to relocate the team angered many fans and politicians, even if it eventually pushed the stadium deal forward. Some supporters also argue payroll spending has lagged behind bigger market teams, and Forbes data shows the club posted a negative operating income in the most recent season on record.
Overall, Kendrick’s stewardship looks like a mixed but largely stabilizing chapter for a franchise that once faced serious financial trouble.
Are The Arizona Diamondbacks For Sale In 2026
There is no public sale process for the Arizona Diamondbacks right now. Kendrick, now in his eighties, continues to serve as managing general partner and has given no public indication that he plans to sell his stake or step away.
Rob Walton’s quiet purchase of a minority stake has fueled speculation about succession planning, since a wealthy new partner is sometimes a sign that a bigger ownership change could eventually follow. Still, nothing reported so far points to a full sale or a change in control in the near future.
