Rising NRL star James Tedesco will leave the Wests Tigers at the end of the season after signing a three-year deal with Canberra from 2015.
The Tigers had been desperate to hang onto the off-contract young fullback but could not match the lucrative offer from the Raiders.
Tedesco will replace current Raiders fullback Anthony Milford who will join Brisbane next year.
Reports emerged at the weekend that the Tigers had issued a 5pm deadline on Monday for Tedesco to decide his future, but both the 21-year-old's manager Sam Ayoub and club boss Grant Meyer hosed down the claims.
Raiders chief executive Don Furner labelled Tedesco a "marquee" signing, adding that the club had been following his progress through his junior years.
