The Marvel Cinematic Universe might be about to break the internet. Rumors reached a breaking point on May 15, 2026, after Robert Downey Jr. was photographed leaving a secure studio lot in Atlanta where the next Avengers installment is currently filming. While Disney has officially stated that Tony Stark’s story ended in Endgame, fans are speculating about a Multiverse variant or a flashback sequence. “The energy on set is electric,” a leaker posted on X. Whether it’s a cameo or a full return, the “RDJ effect” is already driving Marvel’s stock prices upward.
