iPredict traders think the Trading Among Farmers proposal will be approved by Fonterra shareholders without any changes.
The giant dairy co-operative's board will present the proposal this week.
Early trading suggests there is a 65% chance of approval of the scheme, which would allow farmers to trade shares among themselves instead of with Fonterra.
Traders are also giving Colin Armer - Fonterra's supplier relations committee chairman - a 45% chance of taking over from Sir Henry van der Heyden as board chairman later this year.
