The 55-year-old has been affiliated with the UFC since 1997.
He interviewed fighters at UFC 12: Judgement Day, then became a colour commentator after initially working for free.
Rogan has now revealed that he'll walk away from the UFC when White leaves.
Speaking on his podcast, he claims it's written in his contract.
"I’m a professional fan," Rogan said on a recent episode of The Joe Rogan Experience.
He added: "If Dana (White) leaves, I’m gone. That’s in my contract."
Rogan is one of the company's longest-tenured employees.
And someone who White greatly appreciates as he credited the former Fear Factor host with helping the extraordinary growth of the UFC.
"Part of the reason we’ve grown so fast is because Rogan’s ability to walk you through what’s going on while it’s happening," the UFC boss explained.
"He’s brilliant, he’s so good, and he’s so passionate about the sport.
"This is not a guy who is just there for the paycheck, this is a guy who loves this stuff.
"We didn’t pay Rogan the first 12 events he worked, he did them for free."
UFC legends Michael Bisping and Daniel Cormier as well as Paul Felder could be potential suitors to replace Rogan should he leave the promotion.
Bisping, Cormier and Felder have provided commentary for UFC shows, with the ex-UFC middleweight champion replacing Rogan as part of the broadcast team for UFC 271.
