Less than two years before the Athletics move to Las Vegas, the Major League Baseball franchise has a new investment partner.

Harbinger Sports Partners, an investment fund led by Dallas Mavericks minority owner Mark Cuban, is buying a minority stake in the A's. The news was first reported by Front Office Sports. 

The size of the stake nor the sales price were disclosed. Forbes values the A's at $2 billion, placing the ballclub 18th out of 30 Major League Baseball teams. 

The A's confirmed the investment in a statement.

"Adding the experience of Harbinger's principals across sports, media, and entertainment, combined with their long-term perspective, makes them a valuable addition to our ownership group as we work to build the future of the franchise in Las Vegas," said A's spokeswoman Catherine Aker.

In addition to Cuban, who sold a 73 percent stake in the Dallas Mavericks to Las Vegas Sands controlling shareholder Miriam Adelson and her son-in-law Patrick Dumont in 2023, Harbinger Sports is led by Atlanta Falcons minority owner Rashaun Williams. The sports-focused private-equity firm launched last May.  

According to Bloomberg, Harbinger General Partner Jonathan Mariner, a former Major League Baseball chief financial officer, said teams "are undervalued." He "sees upside in franchises" as upcoming media rights and labor negotiations could "reshape the league's economics and push team valuations higher."

In an interview with The Nevada Independent in June, A's owner John Fisher said the team brought in new investment partners, including partners from Asia that would expand the A's global reach. He declined at the time to name the investors.

The A's are building a $2 billion, 33,000-fan capacity stadium on the Strip that is expected to open in time for the 2028 season. 

The A's are playing home games at a 14,000-seat minor league ballpark in Sacramento until the new stadium is ready. In June, the A's played six regular season home games at Las Vegas Ballpark and have scheduled another six games in Las Vegas next year.

The Fisher family is funding the bulk of the stadium's overall cost. U.S. Bank and Goldman Sachs are loaning the team $300 million for the stadium's construction. Another $350 million will come from public financing provided through the passage of SB1 by the Legislature in 2023.
