The Frenchman has signed a three-year contract at Hull, which includes the option of an extra year.
The 25-year-old arrives at the KCOM stadium having scored 31 times for Wolves, adding extra firepower to Hull’s attacking options in the Championship this season.
Speaking on his move to the club website, Dicko revealed: “I am really happy to be here and hopefully it is going to be a good time for the Club and for me.”
“It’s a move that has been on the cards for a couple of weeks, ever since Wolves played Hull up here. I found out that Hull were interested in signing me and things started moving from there.”
“I’m glad that everything is sorted now and I’m looking forward to settling down here and getting started.”
