Contests settled after recording rising shares (7,2)

'shares' is the definition.
('divvy up' can be a synonym of 'share')

'contests settled after recording rising' is the wordplay.
I cannot quite understand how this works, but
'contests' could be 'vies' (to vie is to struggle or contend with) and 'vies' is located in the answer.
'rising' could be 'up' (similar in meaning) and 'up' is located in the answer.
The remaining letters 'div' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
