Baltimore, Maryland – Major League Baseball’s Baltimore Orioles have added new leadership to their ownership group, with Mark Ein acquiring a minority stake in the team, according to an Orioles spokesperson. The details of Ein’s ownership share have not been publicly disclosed, but his involvement represents a significant expansion of the Orioles’ ownership roster.
Details of the Ownership Change
Bloomberg first reported the news that Mark Ein, founder and CEO of Venturehouse Group, has joined the Orioles’ ownership team. Ein’s addition comes as part of a broader group led by noted investor David Rubenstein, which purchased the Orioles in August 2024 for a total price of approximately $1.7 billion. The exact size of Ein’s minority ownership stake remains confidential, but his involvement signals a strategic move to bolster the team’s business connections.
Background of Mark Ein
Mark Ein has a notable business background, having founded and led multiple successful ventures. He is the chairman of Kastle Systems, one of the leading private security companies in the Greater Washington area. Ein also owns the Washington City Paper and serves as co-chair of the board for Lindblad Expeditions, a publicly traded travel company. Over his career, Ein has been involved with at least six companies that have grown to valuations exceeding $1 billion, highlighting his influence in the business sector.
He has previous experience in sports investments, notably being part of a group that purchased the Washington Commanders in 2023 for over $6 billion. Ein is also a part-owner of Leeds United, an English Premier League soccer team, and has made broad contributions to Washington’s tennis community, including ownership of the Washington Kastles and the tenant tournament, the DC Open.
Goals for the Orioles
Ein’s primary goal in joining the Orioles ownership group is to strengthen the team’s connection with the business community in Washington, D.C. This aligns with the broader strategy of Rubenstein, who has emphasized expanding the team’s regional ties and community engagement. The Orioles’ ownership group already includes other minority members with connections to D.C., such as Greg Baroni and Michele Kang.
Greg Baroni owns multiple local sports teams, and his company, Attain Sports, recently reestablished the Frederick Keys as an Orioles minor league affiliate, further emphasizing D.C. and Maryland ties. Michele Kang, owner of the National Women’s Soccer League’s Washington Spirit, has also been involved in the team’s ownership.
Previous Business and Sports Investments
Aside from his role in the Orioles, Ein’s sports involvement extends to ownership of the Washington Kastles, a World TeamTennis franchise that has won six championships, and the DC Open tennis tournament he acquired in 2019. These activities demonstrate his active role in supporting professional sports and community engagement through sporting events.
Context and Significance
The addition of Mark Ein to the Orioles ownership group highlights the team’s ongoing efforts to deepen local ties and leverage Ein’s extensive business and sports experience. It also reflects a broader trend of integrating prominent D.C.-area businessmen into regional sports ownership, reinforcing the Orioles’ regional identity and community presence.
