They will mark the fifth Summer Olympics, and ninth Olympics overall to be hosted by the United States; having previously hosted the Summer Olympics in 1932 and 1984, Los Angeles becomes the third three-time host city after London (1908, 1948, 2012) and Paris (1900, 1924, 2024), and the first non-European city to do so. These will be the first Summer Olympics held under the IOC presidency of Kirsty Coventry.
After debuting in 2020 as optional events, skateboarding, sport climbing, and surfing have been promoted to the Summer Olympics' core event program. The Games will feature the debut of flag football and squash as optional sports, joined by the return of baseball/softball, cricket (for the first time since 1900) and lacrosse (for the first time as a medal event since 1908). The modern pentathlon is expected to feature an updated format replacing show jumping with obstacle course racing.
