Holmes was hit with two counts of first degree murder for each of the victims he fatally shot, and then two counts of attempted murder for each of the 70 others who were injured but survived.
Holmes stood expressionless as the judge read the verdicts for roughly an hour, wearing glasses, khakis and a blue button down shirt.
The 27-year-old admitted to the killings, but argued that he was not guilty by reason of insanity. His attorneys were pushing for him to be committed to a mental hospital for the rest of his life while state prosecutors were seeking the death penalty.
The sentencing phase is separate from this trial and is expected to start next week with an entirely different jury.
The trial began in April and the prosecutors called dozens of victims and witnesses who were in the theater at the time of the shooting, many detailing their injuries or the deaths of loved ones that had attended the midnight screening of "The Dark Knight Rises" on July 20, 2012.
Holmes never took the stand during the trial, though he was present in the courtroom, as were members of his family.
The jury, made up of nine women and three men, considered 11 weeks of emotional testimony from more than 200 witnesses, including victims, first responders and Holmes’ graduate school classmates.
The jury also saw the autopsy reports of the victims who died, handled the three guns he used to killed them and passed around the ammunition which was taken out of their bodies.
Though the defendant didn't take the stand, the jury did hear from him via the 22 hours of recorded psychiatric interviews at both at the Colorado Mental Health Institute in Pueblo and at the jail where he is being held.
Two defense psychiatrists testified that Holmes suffered a psychotic break the night of the murders and could not discern between right and wrong, but two court-appointed psychiatrists told the jury the defendant was mentally ill that night, but not insane.
