Specifically, will Barbie and Oppenheimer break the current pareto frontier for the top 2 movies weekend domestic gross sales on their opening weekend?

The current pareto frontier is depicted here:

And the data presented in a table:

For example, if both movies open with a box office equivalent to The Little Mermaid ($95.5 M) this market would resolve YES (just barely sneaking in the top left corner!). If one opens at $95M and the other opens at $85M, this point would not surpass the frontier and the market would resolve NO.

The box office data will be sourced from the Domestic tab at https://www.boxofficemojo.com/weekend/

If Barbie or Oppenheimer change their release date such that they do not open on the same day this market will resolve ambiguously.
