The Italian side are considering making a January move for the highly-rated England international.
Cahill was strongly linked with a move to Arsenal this summer, but Arsene Wenger instead signed German star Per Mertesacker.
Cahill’s current contract with Bolton is set to expire at the end of the season and the defender could sign a pre-contract with Inter in January.
Bolton are reportedly ready to sell Cahill in January for around £6million instead of risk losing the defender on a free transfer at the end of the season.
