But the German is also open to "the possibility" of a change.
"It (an alternate team) would have to be a clear step forwards," the former Toyota driver is quoted by DPA news agency.
"But at the moment I am fulfilling my contract and so I am not in talks with anyone else," added Glock.
The 30-year-old is one of the more highly-regarded of the drivers at the back of the grid.
And his stock rose even higher when in Singapore his 12th place leapfrogged Marussia ahead of Caterham for the lucrative tenth place in the constructors' championship.
He said in Korea he is open to something new.
"I would then consider what my thoughts are," said Glock.
But if he stays at Marussia, he hopes his help in securing the team millions in Concorde earnings is the step forward the former Virgin team needs.
"That would help us to develop much more, making life a bit easier for us," said Glock.
