founded Monumental Sports & Entertainment in 2010. American businessman and senior
AOL executive
Ted Leonsis, who had owned the
NHL team
Washington Capitals since 1999, founded Monumental Sports & Entertainment on June 10, 2010, following his acquisition of the
NBA team
Washington Wizards and the merger of Lincoln Holdings and Washington Sports & Entertainment. Minority shareholders of Monumental include the
Qatar Investment Authority,
Jeffrey Skoll,
Sheila Johnson,
Mark Lerner and
Arctos Partners. The structure would be part of an arts and entertainment district at the site, which would include a practice facility, restaurants, an
esports venue, concert hall, and a new headquarters for Monumental. In March 2024, after officials in Alexandria announced that the $2 billion entertainment and sports complex plans were scrapped, Washington D.C. mayor
Muriel Bowser announced a new deal to keep the Capitals and Wizards in the District until 2050. In July, Monumental was valued by
CNBC at $7.84 billion. In December 2025, MSE announced that
Laurene Powell Jobs, a minority shareholder since 2017, had sold her stake to Arctos Partners and the Qatar Investment Authority. As part of the deal, the Qatar Investment Authority increased its shareholding of the company. ==Brands and properties==
