At the 2000 Summer Olympics in Sydney, Guliyev competed for the second time in the 50 m freestyle. He received a ticket from FINA, under a Universality program, in an entry time of 24.00. He challenged seven other swimmers in heat three, including fellow two-time Olympian Howard Hinds of the Netherlands Antilles. He edged out Angola's 17-year-old João Aguiar to snatch a seventh spot by 0.34 of a second in 25.36. Guliyev failed to advance into the semifinals, as he placed sixtieth overall in the prelims.
