The 23-year-old goalkeeper is currently on loan at Fir Park from Everton, with that deal set to run until January.
"I would definitely like to stay at Motherwell beyond Christmas," Ruddy told the Daily Record.
"There are a lot of things to be achieved before that but I don't want to talk too much about my future as we have big games coming up.
"I'm 100 per cent focused on doing my best for Motherwell and we'll see what happens on January 2 and that will be down to the clubs and anyone else who comes in.
"It's out of my hands.
"I've always said if I'm contracted to Everton then I want to play first-team football with them but if that's not to be I'm not afraid to leave."
