Both blockbusters are currently in theaters. I will compare their global gross, listed by BoxOfficeMojo, once both have completed their initial theatrical run in major regions. (To save time, if resolution is clear and both movies are only earning trivial grosses that won't change the result, I may resolve early).

Resolution sources:

• Jurassic World: Rebirth

• Fantastic Four: First Step

Example: If F4 grosses $600M, then this resolves YES if JW:R grosses >$900M, and NO otherwise.
