Los Angeles is set to announce it will host the 2028 Olympic Games, meaning Paris will stage the 2024 edition.
In June, the International Olympic Committee voted to name hosts for successive Games – with just Paris and Los Angeles bidding – but it was unclear which would host in which year.
Both cities had wanted to host the 2024 event.
But at a news conference scheduled for 01:00 BST on Tuesday, the LA bid will announce it has agreed to host in 2028.
A source close to the negotiations told BBC Sport that for LA to have accepted the 2028 Games there will have had to have been significant financial benefits that outweigh the benefit of hosting in 2024.
The International Olympic Committee wanted LA and Paris to reach an agreement by September and had they not, a vote to select the 2024 host would have been held.
