Roma are owned by an American investment group, which acquired the team in 2011, and Pallotta played down the takeover claims.
"Qatar Sports Investments want to acquire Roma? There is nothing to it. This is fake," Pallotta told RomaPress in response to a report published by French newspaper Le Parisien.
Roma, who reached the Champions League semi-finals last season, have struggled this term.
After sacking Eusebio Di Francesco in March and appointing former boss Claudio Ranieri until the end of the season, Roma sit fifth in Serie A.
The club are a point behind fourth-placed Atalanta, who occupy the final Champions League qualifying spot with four matches remaining.
The club have a tricky run in as well, with Juventus still on the schedule following the clash with Genoa.
The Serie A side made it to the knockout rounds of the Champions League again this season, but unlike last year when they pulled off an upset of Barcelona to reach the semi-finals, this season’s side fell to Porto in the round of 16.
They are unbeaten in their last five league matches, however, having claimed three wins and two draws in that time.
