Cuban-backed Athletics move to Las Vegas

In late July 2026, Harbinger Sports Partners – a fund led by entrepreneur Mark Cuban and joined by other sports executives – announced the purchase of an undisclosed minority stake in Major League Baseball’s Oakland Athletics. The investment was timed with the franchise’s planned relocation to Las Vegas, where majority owner John Fisher is overseeing construction of a $2 billion, 33,000‑seat domed stadium slated to open for the 2028 season. The deal added financial backing and sports‑industry expertise to a project already funded by public money and private loans.

A week later, Cuban’s involvement was detailed further: the Harbinger fund, valued at $750 million, represents Cuban’s first ownership interest in MLB after selling his majority stake in the Dallas Mavericks. The minority stake aligns with the Athletics’ move to Las Vegas and reflects Cuban’s strategy of treating sports franchises as growth‑oriented entertainment businesses. The announcement also referenced Cuban’s earlier comment that his Mavericks sale was a “mistake,” underscoring his shift toward new sports‑market opportunities.
