Henderson's management team thinks he may fight Gilbert Melendez next.
"We really like the Gilbert Melendez fight, and I'll tell you why: Gilbert Melendez has been ranked either No. 1, No. 2 or No. 3 between himself, Frankie Edgar and Benson," Henderson's manager, Malki Kawa, told MMAjunkie.com (www.mmajunkie.com). "Frankie was considered No. 1 in the world, and Benson beat him. Now some people are saying Gilbert might be No. 1 in the world. OK, well Benson would like to beat him, too, and leave no doubt that he is the best 155-pounder in the world.
"Depending on whose poll you look at over the past few years, it's been those guys in the top three spots, and Benson definitely wants to fight the best guys in the world. He's already defeated Frankie. Beating Gilbert would prove that Benson is absolutely the best lightweight in MMA."
Henderson announced the deal via Twitter.
"Proud to announce that I just signed my new contract, which will keep me around for at least eight more fight," Henderson wrote. "This deal made me think long-term and what it all means and what I'm here for.
"I hope I can use these few years to really inspire, introduce, encourage and do some of His will."
Henderson, 29, is riding a six-fight win streak, including back-to-back wins over Frankie Edgar and a hard-fought brawl against Nate Diaz.
