After the board's quarterly meeting Tuesday, chairman Larry Probst said the USOC was contacting cities that had expressed interest in a possible bid but declined to say which cities were still in the running.
Los Angeles, San Francisco, Boston and Washington were among those receiving serious consideration.
Chicago was the most recent U.S. city to bid for the Olympics, finishing last in voting for the 2016 Games.
But the board hasn't yet decided if the committee will make a bid for the 2024 games. Probst said before the USOC commits to a bid, members want to see what changes the International Olympic Committee makes to the selection process at meetings later this year.
The board will come out with more information in the next 10 days, Probst said.
