Recent footage attached to the Avengers: Endgame Encore re-release has confirmed Mark Ruffalo’s Hulk and several TVA agents for Avengers: Doomsday, while directors Joe and Anthony Russo publicly teased additional unannounced cast members still in post-production. These updates, combined with the film’s multiverse premise and December 18 release, have pushed Polymarket-implied probabilities above 90% for high-profile returns such as Hugh Jackman’s Wolverine and Tobey Maguire’s Spider-Man, even absent official confirmation. The already vast announced lineup spans MCU veterans, the Fantastic Four, Fox-era X-Men, and Thunderbolts players, underscoring the movie’s scale and the market’s focus on surprise cameos that could shift quickly with final trailers or guild previews.
