Local media reported that the move to Al Hilal came after Benzema rejected an offer to extend his contract with Al Ittihad. The former France international striker had missed the team’s previous two league matches.
"Karim Benzema is officially Hilali," Al Hilal posted on X.
The former Real Madrid striker, 38, scored 16 goals in 21 matches for Al-Ittihad in all competitions this season.
