While both cities appeared initially opposed to this compromise, Los Angeles had indicated that it would be willing to consider it if certain concessions were made after it was revealed that Paris was the "Favourite" for 2024.

The IOC set up a process where the LA 2024 bid committee, the Paris 2024 bid committee and the IOC would meet and discuss who would take which games and if it were possible. On 31 July 2017, Los Angeles announced it would withdraw from the 2024 bid race and bid exclusively for the 2028 games. Both Paris and Los Angeles bid committees displayed victory and satisfaction and welcomed the double hosting decision.
