July 23, 2026 - 20:33

A new sports investment firm has made its first move, buying into the team that will soon call Las Vegas home. Mark Cuban and Rashaun Williams, through their recently formed Harbinger Sports Partners, have acquired a minority ownership stake in the Athletics. The franchise is currently in the process of relocating from Oakland to Las Vegas.

Harbinger Sports Partners was established last May. This deal marks the firm's first official investment. The purchase gives the group a piece of the team as it navigates its transition to a new city and a new ballpark. The A's are planning to build a stadium on the Las Vegas Strip, with a target opening in 2028.

Cuban, best known for his ownership of the Dallas Mavericks and his role on the television show "Shark Tank," brings significant experience in team ownership. Williams is a venture capitalist and investor who has focused on sports and entertainment assets. Their involvement signals confidence in the long-term value of the franchise as it plants roots in a major new market. The exact size of the stake and the financial terms of the deal were not disclosed.
