"The countries that have preference over us (in rotation of hosting the event) - Peru, Venezuela and Argentina - have all supported Brazil's candidacy," CBF President Ricardo Teixeira said.
Speaking from the national team training venue, Granja Comary, outside Rio de Janeiro, Teixeira said he expected the South American Football Confederation (CSF) to announce a decision "in the next hours or by tomorrow."
Earlier Thursday, the CSF said nine out of the 10 member countries requested the venue change after a vice-president for the Colombian Football Federation was abducted on Monday by suspected Marxist guerrillas.
Teixeira dismissed speculation that the Copa America would be held in Brazil's three southernmost states, which are not affected by energy rationing imposed by the government to get through an acute electricity shortage.
But he stressed Brazil's ripe conditions to take over the continent's top international tournament in the eleventh hour.
"It's a zero-cost operation for the Brazilian federation because we have all the stadiums ready to go and all the other expenses are funded by the sponsors. As a matter of fact, it is cheaper for us to have the Copa here because we don't need to send the national team to Colombia."
The Copa America features 10 South American countries plus Mexico and one invited country, which this year will be Canada. It was scheduled for July 11-29.
Brazil last hosted the Copa America in 1989.
The Brazilian Football Federation (CBF) said it submitted on Thursday what it believes to be a winning bid to host next month's Copa America soccer tournament after South America's federations vetoed Colombia over concerns of kidnapping and violence.
