It was reported yesterday that Union J, Ella Henderson and Jahmene Douglas would all get signed, with Simon Cowell apparently offering them all "lavish" record deals.
Union J's mentor Louis Walsh, even though he is not their manager, has been working with the group to get them signed.
A source said: "Louis always looks after his acts and he knows exactly hat they need to do.
"They've already had massive interest from labels and a few offers."
The insider continued: "Nothing will be signed until next year, after The X Factor tour, but it's a great start.
"They've got their own management already and Louis believes they could be as big as One Direction."
Feeling positive about the future, lead singer Jaymi said after their fourth place finish in the competition: "Nine times out of ten it is actually better not to win. We get the option to really work on our artistry.
"We get the time, but not the pressure of being winners to sit own and work out what style of music we want to do and make us a brand."
