Hull are said to have fought off interest from other clubs around Europe to sign Stroud, who has joined the Tigers on a four-year deal - with an option to extend by a further 12 months - for an undisclosed fee.
Stroud, who can operate in various positions on the left side, played in all four of Sweden's matches at the 2026 World Cup in the summer despite only making his international debut in the pre-tournament warm-up matches.
He attracted the interest of national team manager Graham Potter after starring for Mjallby in their shock Allsvenskan title win in 2025, scoring nine times and producing five assists across 28 league appearances. He also helped the team from the fishing village win the Swedish Cup earlier this year, and added a further four goal involvements in 10 Allsvenskan matches in 2026.
His final game for Mjallby saw him score from the penalty spot in the UEFA Champions League qualifier against Slovan Bratislava on 4th August, only for his side to concede late in a 2-1 first-leg defeat.
The 24-year-old has an English father, but will now play outside of Sweden for the first time, having come through the ranks at IK Oddevold.
I am super happy and super excited to get started here. When I first heard of the interest, it was the only thing I wanted to do.
“I spoke with the chairman and I got an even better impression of the club and everything around it," he told the Hull City website. “I have individual hopes to play at the highest level possible. When an opportunity like this comes, it’s not something you take lightly. To do it here in Hull is a very exciting opportunity.
“I had a fantastic time at Mjallby. We had an amazing run, won the cup, the league. I felt I was ready for the next chapter and I’m really looking forward to making some statements here as well."
