That could mean trouble for Chicago 2016.
IOC member Denis Oswald said the USOC must make a concession on the contract next week during a meeting in Denver.
Under the open-ended contract, the USOC receives nearly 13 percent of Olympic television rights fees and 20 percent of global marketing revenues -- as much as other national bodies combined.
Oswald says if the U.S. shows no sign of agreeing to a new formula, he will recommend terminating the contract and renegotiating a new deal.
