DiCaprio is nominated in the best actor category for his performance in "The Revenant".
Even though her own "Steve Jobs" co-star Michael Fassbender is also vying for the title, Winslet, 40, said one can "sort of feel" the win will belong to DiCaprio, reported the BBC.
"I think you can sort of feel it, and I think that everyone wants it for [DiCaprio]," said Winslet, who is also an Oscars front-runner for best supporting actress for her act in "Steve Jobs".
Winslet was speaking at the London Critics Circle Film Awards.
She collected her best supporting actress award for "Steve Jobs", just one week after winning the same prize at the Golden Globes.
