Will Doctor Doom Actually Die in Avengers: Doomsday?

This is the biggest question in the market, and it isn’t on the board. Avengers: Secret Wars follows in December 2027, and Doctor Doom is the villain at the heart of the Secret Wars story in the comics. Marvel didn’t bring back Robert Downey Jr. for a single film, and the Russo brothers are directing both movies, so there’s a real chance Doom walks away from Doomsday alive.

There’s no “nobody” option in this market, so read BetOnline’s rules on how it settles before you bet. If you think Doom survives, the best bet here might be no bet at all. If you think Marvel goes for the big shock and takes him out, there’s real value on the board, because the prices are long right across the field.

Avengers Doomsday Predictions: Breaking Down the Board

Thor: +200

Thor is the favorite for good reason. He’s the most powerful Avenger still standing, Chris Hemsworth has been with the MCU since 2011, and he has unfinished business with big villains. Fans will remember his “you should have gone for the head” moment against Thanos in Infinity War, also directed by the Russos. +200 implies a one-in-three chance, which is short for a market with 21 options.

Captain America: +300

This one needs a closer look. Anthony Mackie’s Sam Wilson is Captain America now, but Chris Evans is also back as Steve Rogers. Check how BetOnline settles this option if Steve Rogers lands the final blow, because a market that names a title rather than a person can be settled either way. If the rules cover both, +300 looks a lot more interesting.

Loki: +500

Tom Hiddleston’s Loki ended his own series holding the multiverse together, and Doomsday is a multiverse story. That makes him a natural fit for the climax. A villain-turned-hero delivering the final blow is very on brand for Marvel.

The Fantastic Four: Mister Fantastic Is Our Pick

Mister Fantastic +600, The Thing +700, Human Torch +800, Invisible Woman +1600

In the comics, Doctor Doom is the Fantastic Four’s villain above anyone else, and Reed Richards is his great rival. The two were college classmates, and Doom has spent decades trying to prove he’s the smarter man. With Pedro Pascal’s Reed now in the MCU, it would make sense for Doom’s story to come down to him. At +600, Mister Fantastic is our pick of the board.

The X-Men: Magneto Leads the Mutants

Magneto +1600, Professor X +2000, Cyclops +3300, Gambit +3300, Beast +3300, Nightcrawler +4000, Mystique +4000

The return of the original X-Men cast is one of the big stories of the film. Ian McKellen’s Magneto is the shortest of the mutants, and as the X-Man most willing to kill, that makes sense. Patrick Stewart’s Professor X at +2000 is the other X-Men option worth a look.

The Thunderbolts: Sentry Is the Long Shot

U.S. Agent +4000, Red Guardian +4000, Ghost +5000, Sentry +5000

Lewis Pullman’s Sentry is one of the most powerful beings in all of Marvel, so if it takes raw strength to finish off Doom, he’s a candidate. At +5000, joint-longest on the board, he’s our long shot.

The Rest of the Field

Shang-Chi +1000, Black Panther +1200, Ant-Man +1400

Letitia Wright’s Shuri as Black Panther brings her own history with Doom from the comics, and Paul Rudd’s Ant-Man was the unlikely hero of the Endgame time heist. Neither is short enough to stand out, though.

Avengers: Doomsday Release Date and Cast

Avengers: Doomsday is released in theaters on Friday, December 18, 2026, directed by Joe and Anthony Russo. It shares its opening day with Dune: Part Three, so it’s one of the biggest box office weekends in years.

The cast is huge. Alongside Robert Downey Jr.’s Doctor Doom, it brings together the Avengers (Chris Hemsworth, Anthony Mackie, Chris Evans, Tom Hiddleston, Paul Rudd, Simu Liu and Letitia Wright), the Fantastic Four (Pedro Pascal, Vanessa Kirby, Joseph Quinn and Ebon Moss-Bachrach), the Thunderbolts (Florence Pugh, David Harbour, Sebastian Stan, Wyatt Russell, Hannah John-Kamen and Lewis Pullman) and the original X-Men (Patrick Stewart, Ian McKellen, James Marsden, Kelsey Grammer, Rebecca Romijn, Alan Cumming and Channing Tatum).

How to Bet on Avengers: Doomsday

How This Market Works

Pick the character you think will kill Doctor Doom at moneyline odds. A $100 bet on Mister Fantastic at +600 returns $600 profit if he lands the final blow. The market closes on December 18, release day.

Watch Out for Leaks

Big Marvel films usually hold their premieres and press screenings a week or more before release, and plot details can leak online before the market closes. If you’re going to bet, the safest time is before the premiere. Once the leaks start, the odds can move fast, and they may come off the board altogether.
