Besides leading in the interim presidential tally, President Uhuru Kenyatta's Jubilee Party is projected to control the next Parliament and a majority of counties.
An analysis of results transmitted to the IEBC portal shows JP will dethrone NASA chief Raila Odinga's ODM as the single largest party in the National Assembly.
However, Jubilee will have to get into post-election coalitions with a number of parties to get the required 174 members to form the majority in Parliament.
The ruling coalition has already captured 144 MP seats from the 290 constituencies and 26 woman representative posts in the 47 counties.
ODM follows with 63 MPs and 10 woman MPs while Kalonzo Musyoka's Wiper is third with 20 MPs and three woman representatives.
Majority control in Parliament requires a party or a coalition to get the most number of elected members - MPs and representatives. This means a party or coalition must have at least 174 members.
In the Senate, Jubilee Party has already captured 24 seats while ODM has 13 Senators.
Wiper has three, Amani National Congress and KANU two each while CCU, Ford Kenya and PDR each have one.
Uhuru's party has also captured 25 governor positions compared to the orange party's 13.
Ford Kenya and Wiper have two governors each while two winners for county chief positions were independent candidates.
KANU, Maendeleo Chap Chap and Narc each have one governor each.
The Opposition leader has disputed the unofficial presidential results saying there were irregularities.
Jubilee and NASA teams are examining forms 34A and 34 B at Bomas of Kenya in Nairobi which is the national tally centre.
