The Brazilian midfielder is in advanced talks with the new MLS outfit, who confirmed that the AC Milan man would join up with the team in January
The 32-year-old only re-joined the Italian side last summer after a four-year spell at Real Madrid but has endured an unsuccessful campaign back in Serie A.
Kaka - who has previously talked up a move to the MLS - is now nearing a move to Florida to play with new MLS franchise, Orlando City.
"Orlando City Soccer Club is in advanced discussions with Kaka. Pending completion of the potential player agreement, Kaka would join Orlando City SC in January 2015 prior to the Club’s first season in Major League Soccer.
"The Club will have no additional comment until further notice.”
The Brazil international - who has scored 29 goals in 87 caps for the Selecao - won the Champions League with Milan in 2007 as well as Serie A and La Liga titles with Los Blancos.
Kaka recently admitted he would like to play in American if things did not work out at Milan.
"One day, I would like to play in America. At the end of the season, I will talk to [general manager Adriano Galliani]. Not just to speak about bonuses and money -- money is not the main thing for me now, and I think that is understood," Kaka was quoted as telling Italian newspaper Corriere della Sera earlier this year.
"I want to see what his ideas are and what the club’s ideas are. If it turns out I need to move, I will choose the MLS."
Should Kaka finalise his transfer to Orlando City, he would become the second biggest name to go to the MLS following David Villa's move to New York City from Spanish champions Atletico Madrid this summer.
