I will use the "Audience Score" listed on Rotten Tomatoes, two weeks after the US release of the Palme d'Or winner.
"GODZILLA X KONG: A NEW EMPIRE": https://www.rottentomatoes.com/m/godzilla_x_kong_the_new_empire
2024 Palme d'Or winner: [To be added once it has been crowned]
Context
The Palme d'Or is the highest prize awarded at the prestigious Cannes Film Festival.
"GODZILLA VS. KONG" has an RT audience score of 91%.
The most recent Palme d'Or winner was "Anatomy of a Fall" with an RT audience score of 90%.
Details
I will resolve this market once both (1) the Palme d'Or winner has reached "100+ verified ratings" (as it currently lists for "Anatomy of a Fall") and (2) it is at least two weeks after its US release date.
There is a small chance that the next Palme d'Or winner does not secure a wide enough US release to reach this mark. While I think that is extremely unlikely, this market resolves N/A in March 1st 2025 if that occurs.
