"I don't want to say this in a braggadocios way, but a person at CNN and a couple of other people said, 'We have to put Donald Trump in this debate. We're going to die with it.' Let's see," Trump continued on Fox.
"I don't think they'll do badly, because there is a curiosity factor. I don't think they're going to do great, and I think a lot of people are going to turn off after a little while."
Five declared Democratic presidential candidates will take to the stage Tuesday in Las Vegas for the first debate. Trump has previously taken credit in part for record audiences for the GOP debates hosted by Fox News and CNN in August and September, respectively.
Asked if former Secretary of State Hillary Clinton, the front-runner for the Democratic nomination, might be nervous for the first debate, Trump said, "I think she's nervous about her whole future," citing continued questions about her email.
Trump also said that he "can't imagine" Sen. Bernie Sanders (I-Vt.) defeating her in the Democratic race, adding, "I can't imagine she'll be allowed to run."
The real estate tycoon also responded to President Obama's criticism of the Republican presidential candidate as a "publicity seeker" during an interview broadcast late Sunday on CBS's "60 Minutes."
"I watched his performance last night and I thought it was terrible," Trump said on Fox.
"I thought it was sad, because everything is negative, you know, nothing positive," Trump said. "I thought it was a little bit sad because there was so much negativity."
Obama said he thought Trump had "tapped into something that exists in the Republican Party that's real," adding, "I think there is genuine anti-immigrant sentiment in the large portion of at least Republican primary voters.
"I don't think it's uniform. He knows how to get attention. He is, you know, the classic reality TV character and, at this early stage, it's not surprising that he's gotten a lot of attention."
