When I watch the Oscars this year, I’m hoping the famously unlucky number 13 will be lucky that night.

There are plenty of 13’s to go around. Oppenheimer leads all films with 13 nominations, the most since The Shape of Water. A total of 13 movies were nominated for at least one of best picture, director, or an acting category. Top contenders like Cillian Murphy, Lily Gladstone, Cord Jefferson, and more each have 13 letters in their names. The word “Ken” appears exactly 13 times in the lyrics of “I’m Just Ken.”

And for me, this marks my 13th year predicting the Oscars with math. This labor of love has come a long way, from a college dorm room to a book and a Twitter account and these annual articles. But the basic concept remains the same: I weight each datapoint based on the track record that predictor (such as precursor awards, other category nominations, betting markets, etc.) has at predicting each category. Some years see plenty of favorites win; some years see a healthy dose of mathematical upsets. Perhaps this year will be a lucky one.
