However, the study conducted between 23rd - 26th July has 4 per cent undecided voters who can tilt the race.
The study had 6,105 respondents from all 47 counties.
The poll comes six days to the August 9 polls.
If elections were to be held today, the poll shows neither Raila nor Ruto, the leading presidential candidates, will garner the 50 plus one required to win the presidency.
This is the first poll to be released by Ipsos Synovate since the campaigns officially started.
