Who will win Best Supporting Actress at the 2026 Oscars?
This race, along with Best Supporting Actor, feels like its up for grabs. Still, a few favorites have begun separating themselves from the field.
Amy Madigan earned her first Oscar nomination since 1986, a Supporting Actress nod for Twice in a Lifetime. It’s a long time coming for the 75-year-old, who has an extensive track record of work on film, television and the stage. In Weapons, Madigan delivered a brilliant performance as the mysterious and sinister Aunt Gladys. This unique, almost indescribable character seems to have won over fans and award voters alike. Madigan has already taken home a Critics’ Choice Award, although she fell short at the Golden Globes. If there’s a downside to this pick, Weapons isn’t represented in any other category at the Academy Awards. Historically, that has held back solo nominees.
Teyana Taylor has already garnered plenty of buzz during awards season. The first-time nominee was electric during the first half of Paul Thomas Anderson’s One Battle After Another. Although her screen time was limited, Taylor’s portrayal of revolutionary Perfidia Beverly Hills is essential to the rest of the film. Managing to steal the show next to Leonardo DiCaprio is no easy task, but she pulled it off. Taylor earned a win in this category at the Golden Globes. OBAA’s status as Best Picture frontrunner should also help, in theory. However, Best Supporting Actor could go to cast mates Sean Penn or Benicio del Toro. If that occurs, voters might want to spread the love in Supporting Actress.
If anyone can challenge Madigan or Taylor, it’ll likely be Wunmi Mosaku. The massive success of Sinners has been somewhat of a breaking out party for the British-Nigerian actress. Having plugged away at various film and TV roles, Ryan Coogler’s blockbuster has elevated her profile within Hollywood. It’s deserved; Mosaku’s Annie, a Hoodoo healer, is in many ways the heart of the story. While a bit of a longshot, it’s clear that the Academy is all-in on Sinners. The film has garnered a record 16 nominations. That level of enthusiasm could easily carry over into the Acting categories.
To wrap things up, we have the duo of Inga Ibsdotter Lilleaas and Elle Fanning in Sentimental Value. The former was a bit of an unknown, having done most of her work in Scandinavian films. However, the Norwegian was phenomenal as Agnes, sister to Renate Reinsve’s Nora. Much like Taylor, Ibsdotter Lilleaas holds her own next to top-notch actors. Ditto for Elle Fanning, one of the more shocking nominations. Her turn as American actress Rachel Kemp added so much to Sentimental Value, and it’s nice that the up-and-coming star got some major recognition. Unfortunately, the two are likely to eat into each other’s chances at this award. Making things more difficult, foreign films usually face an uphill battle in acting categories.
With respect to Mosaku, this one likely comes down to Madigan and Taylor. While one enjoys a more memorable role, the other is part of a film the Academy loves. Ultimately, I think the latter will play a bigger factor. After all, the Oscars have never been kind to the horror genre, and I’m not sure that’ll change on Sunday. At two-to-one odds, I’m leaning towards Taylor.
