A group led by Mark Cuban's Harbinger Sports Partners has acquired a minority stake in the Oakland Athletics in anticipation of the franchise’s 2028 move to Las Vegas, with details on the exact percentage and price not disclosed. The investment program includes notable partners such as Rashaun Williams, Steve Cannon, and Jonathan Mariner, and aims to leverage their experience across sports, media, and entertainment to grow the team’s value. Team owner John Fisher is overseeing the construction of a $2 billion, 33,000-seat domed stadium on the Las Vegas Strip, set to open for the 2028 season as the A’s shift from Sacramento for home games. Forbes values the A’s around $2 billion, reflecting the ongoing valuation upswing as Las Vegas becomes the team’s new market. The announcements emphasize Harbinger’s long-term perspective and the broader strategy of expanding the A’s footprint and global reach ahead of the relocation, while the club continues to play in Sacramento during the transition. Separately, industry coverage notes broader sports investment activity, including parallel developments around related entertainment ventures.
