The 23-year-old has been a first-team regular since joining from Castleford in 2014, and should now stay at the KC Stadium until at least the end of the 2017 season.
“I’m really happy to be committing my future to the club and it really was a simple decision for me make,” said Thompson.
“Last season was probably one of my best years form wise and I’m really enjoying my time in training, so it was a no brainer when I was offered the chance to extend my time here.
“The set of lads here at the moment are closer knit than any squad I have been in before.
“I also can’t think of a camp that I’ve been in that has had more of a positive feeling buzzing around the place, so I’m excited that I’ll be able to continue to work in that environment in the next few years.
“Both Lee Radford and Andy Last gave me the opportunity to play in the forwards regularly last year, which I felt helped develop me as a player.
“I think that a lot of the improvement in my form is down to the guidance they have given me and I’m looking forward to working alongside them for the extended period.”
Hull coach Lee Radford is delighted that such a versatile and skilful forward has extended his stay at the club.
“Jordan’s contract extension is great news for the club as he is a player that I feel has really found his feet in the last eight to ten months,” he said.
“A change in position has aided his development as a Super League player, and he offers the team a lot of versatility, which as a coach is a great weapon to have at your disposal.
“As well as having a strong influence on the pitch, Jordan is a popular member of the group which is equally crucial to the mentality of the team.
“He joins the likes of Chris Green, Josh Bowden, Liam Watts, Dean Hadley and Joe Westerman that we have within our squad in their mid-twenties, that complement the younger kids that are coming through to make a very strong English pack.”
