According to Deadline, Portman is currently in negotiations to play a role in the film.
While character details have not been revealed, the part is said to be a major one, and based on her age and the resemblance, it is speculated that she will take on the role of Lisa, Jobs' daughter, if a deal is made.
Sony first picked up the script by Aaron Sorkin, but dropped it earlier this month. However, the much anticipated film was picked up by Universal Studios and is currently back on track.
The role of Steve Jobs has had many A-list celebrities tied to it including Leonardo DiCaprio, Christian Bale, David Fincher, and most recently, Michael Fassbender.
Another actor set to join the cast is comedian Seth Rogan. Rogan is in talks to play the part of Apple co-founder Steve Wozniak, and if he is chosen, it will mark Rogan's first dramatic role.
Rogan recently talked to IGN News about the part and said he would love to be a part of the project.
"It’s a cool team," he told the website. "There’s a lot that needs to happen between now and then – they haven’t closed the deal with the studio which means they haven’t closed the deals with any of the actors or any of that stuff. But if that movie gets made, I think there’s a good chance that I will be in it."
