Just in time for the move to Las Vegas, the A’s are adding Mark Cuban and Falcons minority owner Rashaun Williams to their ownership group in what represents the first deal for Harbinger Sports Partners, the sports-focused private-equity firm launched last May.
The size of the minority stake, price paid, and team valuation were not disclosed. The A’s have reportedly been trying to sell a minority stake since 2024. Forbes values the A’s at $2 billion, placing them 18th out of 30 MLB teams.
In addition to Cuban and Williams, Harbinger is led by former MLB CFO and EVP Jonathan Mariner and Steve Cannon, who previously served as vice chairman and CEO of Falcons parent company AMBSE.
When Harbinger announced its launch last May, the firm said it was looking to raise $750 million for its first fund, and that it would target minority stake investments in North American sports franchises.
The firm—which intends to make 10 to 12 investments out of its first fund—is actively in talks with other teams and expects to have more announcements in the near term. But starting with the A’s was a deliberate choice, Williams says.
