Lukas Walton, an heir to the Walmart fortune, and his wife Samantha Walton have acquired a minority stake in the Chicago Bulls and the United Center, the team announced Friday. The deal adds one of America's wealthiest families to the ownership group of a franchise still closely tied to the legacy of Michael Jordan's six championship runs.

The Details of the Deal

Lukas Walton and his wife, Samantha, have acquired a minority stake in the Chicago Bulls and the United Center, the team announced Friday. The transaction involves the purchase of existing stakes from limited partners and does not provide Walton with a path to controlling ownership, the team said. The size of the minority stake and the valuation were not disclosed, but a person familiar with the matter told CNBC the Waltons' stake in the team and arena was 10%.

The Bulls said the Waltons' purchase involved buying existing stakes from "certain limited partners," but didn't offer further details. Terms of the agreement were not publicly disclosed. The Wirtz family, which owns the Blackhawks, and the Reinsdorfs will continue to hold controlling interests in the United Center and the now-underway 1901 Project, meaning the franchise's core leadership structure remains unchanged.

The Bulls' Valuation and Ownership History

The transaction values one of the league's most storied franchises at a substantial figure. The Reinsdorf family remains the controlling owner of the Chicago Bulls. Jerry Reinsdorf purchased the team for $16.2 million in 1985. Today, the team is worth approximately $6.45 billion, according to CNBC's most recent NBA valuations, making the franchise the fifth-most valuable in the league. The Bulls have been one of the NBA's most successful franchises in history, winning six championships during the Michael Jordan era.

What Both Sides Are Saying

Bulls leadership framed the addition as a natural extension of shared values around the city's future. "We are pleased to welcome Lukas and Samantha, who share our deep-seated belief in Chicago and our commitment to the institutions that make this city strong," Michael Reinsdorf, president and chief executive officer of the Chicago Bulls, said in a news release. "Together with our partners at the United Center, the Wirtz family, we are fully aligned in our vision for the Bulls, the United Center campus, and the future of the West Side".

The Waltons echoed that civic-minded framing in their own statement. "The Chicago Bulls are as iconic as the city itself, and this transaction reflects our dedication to the city's future. We have long admired the vision the Reinsdorf and Wirtz families have set forth for The 1901 Project, and we look forward to the United Center's continued positive impact on Chicago's West Side," the Waltons said in a statement.

Who Is Lukas Walton?

Walton's wealth places him among the most prominent figures in American sports ownership circles. Lukas Walton, 39, is the grandson of Walmart founder Sam Walton. Along with other members of his family, he is an heir to the mega-retailer. This year, Forbes estimated he was the 40th wealthiest person in America with a net worth of $48.9 billion. He is estimated to be the richest person in Illinois.

This investment continues a broader pattern of Walton family members entering major US sports ownership. Lukas Walton's uncle, Rob Walton, bought the NFL's Denver Broncos in 2022 and also owns a stake in MLB's Arizona Diamondbacks.

Why This Stake Could Matter for the Bulls' Future

Beyond the headline transaction, some analysts see the move as a potential signal of greater financial flexibility for a franchise that has historically been conservative with spending. The Reinsdorfs have long been, quite infamously, reticent to ever dip into the league's punitive luxury tax. Bringing aboard new investors with pockets as deep as the Walton family could signal that Chicago ownership is really serious about not just occasional luxury tax bills, but also perhaps even building out the club's front office and medical staff — two departments that have long been allegedly leaner than the top NBA franchises.

The Bigger Picture: The 1901 Project

The deal also ties directly into a major development initiative already underway around the arena. Chicago officials broke ground earlier this month for the 1901 Project on the city's Near West Side. The $7 billion project is designed to transform development and investment around the United Center, aiming to develop the area around the stadium into an entertainment district with 9,500 new residential units.

What Comes Next

With the Reinsdorf family retaining full control of the Bulls and the United Center, the Waltons' entry is unlikely to trigger any immediate change in day-to-day team operations or front-office structure. The bigger question going forward is whether this minority investment marks the start of deeper financial involvement from the Walton family in Chicago sports — and whether the added capital ultimately translates into greater spending flexibility for a franchise that has long been known for fiscal restraint.
