After McLaren and Mercedes announced their driver lineups for next year, Brazilian Massa was asked about the latest speculation that he is heading for a new Ferrari contract.
It follows Ferrari president Luca di Montezemolo telling Autosprint that he will make the final decision in "two or three days".
"But I have to say that Felipe has driven very well lately," he said.
Massa is confident.
"There is a good chance that I will stay at Ferrari," he told Italy's Sky Sport 24.
"Are my chances good? I certainly think so. I am rather confident in that respect.
"I think a decision will be reached within a short matter of time," added Massa.
