The court heard how Levy, from Tottenham, targeted the three vulnerable women, all of whom carried out street sex work in order to fund drug addictions.
He declined to give evidence during his trial but pleaded not guilty to the two murders, as well as two counts of rape, grievous bodily harm with intent, and non-fatal suffocation against the surviving woman.
The jury, which was given a majority direction in the trial, found him guilty of all charges after 13 hours of deliberation.
Members of the victims' families wept as the verdicts were returned while the defendant, who had a pointed beard and was wearing sunglasses, gave no reaction.
In court, judge Mark Lucraft KC adjourned sentencing until Wednesday 12 August and remanded Levy into custody.
Speaking after the verdicts were given, Det Ch Insp Neil John from the Met said: "Simon Levy is a dangerous and predatory offender.
"His crimes were calculated, cruel and deeply disturbing. Throughout the trial, he has shown complete disregard for the victims and victim-survivor, despite being fully aware of the lasting and devastating impact of his actions."
He described the investigation as "complex and challenging" but said "my team and I have been steadfast in our professionalism and dedication".
Standing alongside Wilkins' two sisters and Valencia-Trujillo's daughter, he asked for any other victim-survivors of Levy to come forward.
Valencia-Trujillo's children said she was a "big character" who was "full of life" and was said to be a "much-loved" member of the community with a love of salsa dancing.
Wilkins' family said she was a much-loved woman who is missed every day by those who knew her.
The Met said since the launch of the investigation, detectives had exhausted numerous lines of enquiry – including working with coroners – to identify whether Levy was responsible for any similar, unsolved incidents, including deaths.
Police have said while they are yet to find anything new on Levy, they emphasised they had significantly strengthened their training and response to violence against women and girls, along with their specialist victim support services.
Ramsarran said the cases had been handled against a backdrop of significant pressure on the criminal justice system, including busy court lists, late or incomplete information, and the need for agencies to make decisions quickly.
While that did not lessen responsibility for the failings, she said it was important to understand the circumstances in which they had occurred.
She said measures were being introduced to strengthen training, improve oversight of cases and enhance the handling of bail and risk assessments in serious sexual offence investigations.
Levy had attacked the three women while on bail for sex assaults on trains in London, and went on to carry out further assaults on public transport.
Ramsarran explained how Levy was convicted in February of sexually assaulting 10 women on London's Tubes and trains.
She added: "Nothing can undo the harm caused, but we hope these convictions provide some measure of justice."
Earlier this year, Levy, 40, was found guilty by a jury at Inner London Crown Court of groping 10 women on the Tube and an 11th while in prison.
Details of this trial can now be reported after his conviction at the Old Bailey.
The offences took place between April 2022 at the prison, followed by the Tube assaults between 24 October 2023 and May 2025.
He had already been convicted of sexually assaulting two women in 2018, which was why he was in prison in 2022.
The sex offender had lost sight in one eye in an attack in May 2024 and played on this, claiming that his partial sight made him unsteady on his feet and all contact was accidental on these crowded trains.
Levy's tactic was to tie a jumper or hoodie around his waist, strap his arm down, and then back towards his victim with his hand fully or partially covered so he could grope them.
One of the Tube assault victims told the court: "It wasn't long before I learned that my attacker was already known to the police for sexual violence and is a convicted sex offender.
"You could not begin to understand the horror I felt at hearing this.
"How could a male who does this so often and so brazenly be allowed to repeat his attacks?
"Knowing this made me feel even more unsafe, the possibility that I could encounter Simon Levy again made me fearful and the idea that he would harm more women and that there would be many more victims was unthinkable."
During the sentencing hearing in June for the Tube attacks, Judge Michael Evans told Levy : "You were on the Tube for one purpose only, to sexually assault women."
Levy was convicted of 11 counts of indecent assault, including grabbing the prison guard in 2022, and given an extended sentence consisting of a six-year jail term plus a three-year period on licence.
