Last month, it was reported that David Cassidy, Gary Busey, Lisa Rinna and Star Jones are among Hatch's competitors.
The former Survivor winner told Access Hollywood that he doesn't worry about anyone else mounting a serious challenge to be named as Donald Trump's next Celebrity Apprentice.
"It's tough to decide who's going to be the… real competition," he said. "I mean, we all know I'm going to win. We just have to wait for that to happen."
Hatch went on to say that he is most excited to be raising funds on behalf of his chosen charity Grassroot Soccer, which seeks to stop the worldwide spread of HIV.
"One of the best parts of having gained the notoriety from having won Survivor is the opportunity to… raise money for really worthwhile causes…. So I'm thrilled to be able to do it."
Previous Celebrity Apprentice winners have included Piers Morgan, Joan Rivers and Bret Michaels.
Celebrity Apprentice premieres March 6 on NBC.
