Though the 30-year-old rapper, whose real name is Rakim Mayers, and his two bodyguards were found to have hit and kicked the victim during the brawl, the three defendants did not face the prospect of an immediate prison term and did not have to attend the verdict by the Stockholm District Court.
The court did sentence the three to "conditional sentences," which means they face no prison sentence in Sweden unless they commit a similar offence in the country again.
The three, who were released August 2 pending the verdict and returned to the U.S., have been ordered to a pay a total of 12,500 kronor ($1,310) in compensation to the victim.
The artist had pleaded self-defense and said he had tried to avoid a confrontation with the two men who he claimed were persistently following his entourage. One of them picked a fight with one of Mayers' two bodyguards, the rapper told during the court proceedings.
The court said the defendants "were not in a situation where they were entitled to self-defense."
"In an overall assessment the court finds that the assault has not been of such a serious nature that a prison sentence must be chosen," the court said.
This sort of sentencing is in line with other cases in Sweden.
During the trial, prosecutors played video footage that showed the rapper throwing a young man to the ground.
Though the victim, 19-year-old Mustafa Jafari, was struck in the back of the head with a bottle, presiding judge Per Lennerbrant said it could "not be established by whom" and this inability "affected the assessment of the seriousness of the crime."
Slobodan Jovicic, Mayers' Swedish defense lawyer was "disappointed" by the verdict and said he had been looking for "a complete acquittal."
Mayers had told the court before his release that Jafari and his friend refused to go away despite several appeals, and claimed they appeared to be under the influence of drugs.
Testifying in court, Jafari said his memory of the events was confused because of the blows to his head during the brawl. He had told police earlier that he got angry as his headphones were broken during the initial argument with a bodyguard.
A full-scale brawl ensued shortly afterward and prosecutors allege that Mayers and his bodyguards — David Rispers, Jr. and Bladimir Corniel — beat and kicked Jafari while he was on the ground. They said Jafari was hit with parts of or a whole bottle.
Jafari claimed the rapper pushed him to the ground. The prosecution played video footage in court showing Mayers throwing a young man to the ground, and photos showed the alleged victim's cuts, bruises, and blood-stained clothes.
The case drew the attention of American celebrities and Mayers' fellow recording artists, including Sean "Diddy" Combs and Justin Bieber. A social media campaign, #JusticeForRocky, has been pressing for his release.
The issue also became a topic of U.S.-Swedish diplomatic spat.
U.S. President Trump intervened on behalf of the rapper while he was jailed, and called Swedish Prime Minister Stefan Lofven, offering to personally guarantee his bail, but the Swedish leader said he couldn't interfere in a legal case. Trump later cheered the release of Mayers and his bodyguards.
