As the first of the weekend's final two live wraps up, bookies BoyleSports report that it is all one way support for Rak-Su to take the title.
The foursome have been heavily backed ahead of the weekend’s final and are firm 2/5 favourites as a result.
The band have come a long way from their initial 12/1 odds and are going to be tough to beat.
Also making the final two is Grace Davies.
Grace was the early frontrunner to win, following her first audition, but was quickly overshadowed by Rak-Su in the live shows.
Tonight saw Kevin Davy White bow out of the competition in third place.
Aoife Heffron, Spokeswoman for BoyleSports commented: “It’s fair to say that the right three made the final, but there can only be one X Factor winner and all signs, bets and odds point to Rak-Su to come out on top.
"The lads have captivated and entertained X Factor judges and viewers from the word go, thanks to their original catchy tracks”
Grace and Rak-Su will be performing again on Sunday night live for the last time this year.
Lines will then close for good before the winner is crowned.
The X Factor 2017 final continues Sunday night at the later time of 7:15PM on ITV where there will be performances from Sam Smith, Little Mix and Pink.
