Television reality show The Voice has achieved record ratings and is also breaking records when it comes to betting on the winner of Sunday's final.
Betting agency Betfair says interest in wagering on the hit program has been unprecedented with a number of significant bets traded on Karise Eden, who is the $1.73 to win The Voice.
Sarah De Bono is second favourite with punters at $3.65.
"It seems our punters have narrowed the contest down to two," Betfair's Mathew Thompson says.
"These entertainment markets are generally novelty value for our punters but interest in The Voice has been unprecedented.
"It is comfortably the most popular entertainment market we've offered in Australia, which reinforces the popularity of the program," Thompson says.
There is also a market on which judge will provide the winner with Team Seal the obvious favourite at $1.65, ahead of Joel Madden at $3.65 after being $7 at one stage.
Eden from Team Seal, De Bono on Team Joel, Team Urban's Darren Percival and Rachael Leahcar from Team Delta will battle it out in the grand final, which goes to air on the Nine Network from 7pm (AEST).
The Voice live final will also see coach Madden sing a duet with his father-in-law Lionel Richie.
The winner of The Voice, will be announced on Monday night.
