Local analysts said the AKP will win 46.5 percent of the vote while the main opposition CHP may get 26.8 percent.
The MHP and the pro-Kurdish Peace and Democracy Party are expected to have 10.8 percent and 6.7 percent respectively, they added.
However, they noted, the ruling party will not reach the 367-seat threshold.
The AKP, which has been in power since 2002, owns a largely conservative electorate and has a pro-business and pro-European Union (EU) platform.
In addition to its popularity among conservatives, the AKP has also secured support from political liberals due to the reforms aimed at Turkey's EU membership.
