Source: BoxOfficeMojo—the cumulative worldwide grosses displayed three months after the release of the latter film (currently, October 3rd).
These options resolve based on the following number ("Difference"):
Difference = ["Despicable Me 4" gross] minus ["Inside Out 2" gross]
Example
The worldwide gross for "Despicable Me 3" (2017) is $1,034,800,131, and the worldwide gross for "Inside Out" (2015) is $858,852,998.
The difference (["Despicable Me 3"] minus ["Inside Out"]) is $175.94 million.
Thus, in an equivalent market, [>$150 million] would resolve YES, and [>$225 million] would resolve NO.
Thanks for adding a bit of liquidity @gallerdude . Sorry this market is poorly configured, I made a few before the economy changes and this one never got traders so it has pointlessly low liquidity. Once we get closer to despicable me 4 release, I’ll probably make some more targeted markers with ok liquidity
