The 22-year-old Australian has signed a new two-year deal with Red Bull but world champions Red Bull Racing will again field Sebastian Vettel and Mark Webber.
Ricciardo thinks that sister team Toro Rosso will retain Sebastien Buemi and Jaime Alguersuari, while he also appears out of the running at HRT, with whom he made his debut this season and who recently announced Pedro de la Rosa as a driver for 2012.
"At the moment it seems like Toro Rosso are going to stay with who they've got," Ricciardo told The West Australian.
"It wasn't put down 100 per cent, but it was the wording I was making out.
"There's a good chance if I'm on the grid next year it's going to be with another non-Red Bull outfit, but I guess the good news is I'm still contracted by Red Bull. They've agreed to continue with me."
Attention has now switched to Team Caterham, who recently changed their name from Team Lotus.
Tony Fernandes's outfit have already confirmed their line-up of Heikki Kovalainen and Jarno Trulli but there are rumours nevertheless that Ricciardo could replace the veteran Italian.
"I would like to say there's a chance, but at least for me that's probably all it is for now, just a chance," assessed Ricciardo.
"It would be a step up from this year, so it's not really a bad thing.
"I doubt they'll still be able to fight for points next year. They'll still be towards the further end, but I think they're progressing well.
"If (Heikki) Kovalainen was to be my team-mate, it's someone very good to measure up to. He's won a grand prix before and he's smashed Trulli this year."
Ricciardo did admit, however, that the role of a reserve driver is not one that appeals to him.
"I'm obviously proud of getting there and doing something that I've dreamed of since I was a kid, but it's probably like everything," he added.
"I've got there now, but I'm not happy just to settle just for that. I want to keep going forward and I believe I can."
