In 2017 he won his second senior national title, moving up to welterweight and defeating Ruslan Sjidokaev in the final for the gold. A few weeks later he won the light-welterweight gold medal at the Nordic Championships, where he was also won the award for best senior male athlete. However, he suffered a quarterfinal exit at the European Championships and a first-round loss to Freudis Rojas at the World Championships. He finished the year by winning the King of the Ring Tournament in Sweden, once again moving up to welterweight and knocking out Nordic champion Adolpe Sylva in the semi-finals before beating the 2016 King of the Ring, Alex Bishop, in the title fight. He was named the best boxer of the tournament. For his multiple gold-medal performances, local publication "Tønsbergs Blad" awarded him the "Kristinastatuetten" given to the Vestfold region's athlete of the year.
