The Cabinet has approved a budget of Sh10 billion for President Uhuru Kenyatta and NASA chief Raila Odinga's repeat election.
The allocation was based on a proposed budget submitted by IEBC.
The proposal followed a petition whose verdict included the cancellation of Uhuru's win and a fresh election in 60 days.
The September 1 decision sent shockwaves through the country and beyond as it was the first of its kind concerning an African president.
