On April 9, 2025, the IOC announced new events in multiple sports, including a 4 × 100m mixed relay in athletics, the addition of 50m backstroke, butterfly, and breaststroke events in swimming, and mixed team compound archery (the discipline's Olympic debut), all-round artistic gymnastics, golf, and table tennis events. In sport climbing, the combined boulder-and-lead event will be replaced by separate competitions for each discipline, expanding it to six medal events. It was also announced that 3x3 basketball would be expanded to 12 teams, one additional women's weight class would be added to boxing for parity with the men's events, women's water polo would be expanded to 12 teams for parity with the men's tournament, while the women's football (soccer) tournament would expand from 12 to 16 due to the increasing popularity of the sport.[88][89] The men's football tournament will be reduced from 16 to 12 teams, while the marathon race walk mixed relay introduced in 2024 was dropped. With these changes, the 2028 Summer Olympics will be the first to have more female than male athletes.[90][72] On September 19, 2025, the IOC announced that one additional weightlifting weight class per gender would be contested.[91]
