The Oscars ceremony held on March 15 featured a mix of expected outcomes and surprising results, particularly in the realm of prediction markets. Platforms like Kalshi and Polymarket demonstrated their predictive capabilities by accurately forecasting the winners in 19 out of 24 Oscar categories. This performance, while impressive, was slightly less successful than their predictions for the Golden Globes, where they identified 26 out of 28 winners.
The prediction markets showed strong accuracy in major categories, including best picture, best director, best actor, best actress, and best screenplay. However, there were five notable categories where the favored films did not secure an Oscar.
In the best cinematography category, "One Battle After Another" was heavily favored but lost to Autumn Durald Arkapaw for "Sinners." Similarly, "Butterfly" was the predicted winner for best animated short film, yet "The Girl Who Cried Pearls" took home the Oscar. The best live action short film category resulted in a rare tie, with both "Two People Exchanging Saliva" and "The Singers" awarded Oscars, although the handling of the tie varied between the platforms—Kalshi allowed for a tie option, while Polymarket determined the winner alphabetically.
In the best documentary feature film category, "The Perfect Neighbor," with strong backing from prediction markets, was defeated by "Mr. Nobody Against Putin." Additionally, "One Battle After Another" won best casting, despite prediction markets indicating a higher probability of a "Sinners" victory.
The outcomes highlight the complexities of prediction markets and their potential to reflect collective insights, albeit with notable exceptions.
