Gradus Kraus, a light heavyweight prospect from the Netherlands, has signed a long-term contract with Boxxer, the promoter announced.

Kraus is 9-0 with eight knockouts, or 12-0 with nine knockouts if you include IBA Pro bouts, which are listed separately on BoxRec. The 24-year-old Kraus is coming off a November 29 victory over the 13-1-2 Rostam Ibrahim, whom he dispatched via second-round knockout.

“The knockout artist is the reigning light heavyweight IBF European champion and ready to fight anyone on the world scene,” Boxxer said in its announcement.

Kraus is not presently ranked by any of the four major sanctioning bodies. His three IBA Pro fights were all in the final quarter of 2023. He has otherwise been a pro boxer only since October 2024.
