The Ghana international's current contract is due to expire at the end of the season and OM are keen to hold on to the 25-year-old.
Nevertheless, Ayew has stressed that he has no intention of accepting a paycut and, while he is happy at Stade Velodrome, he is preparing for a potential exit in the summer.
"OM have financial problems and they cannot afford to pay certain wages," Ayew told RTL.
"I am a Marseille player at this stage and could still stay here. My future is still open.
"There will soon be a meeting to discuss my future. But I will not accept a paycut to stay at OM. Every player wants to make progress, in all aspects.
"If the club want me to leave, then I will go. But I like Marseille."
The versatile attacker joined the Marseille youth academy from Nania in 2005 and has developed into a key player at the Ligue 1 side in the past few seasons.
Ayew has netted four goals in 16 Ligue 1 appearances so far in 2014-15.
