Is it possible to resolve the first option now that Polanski did win the contest?

@dorothydomer unfortunately this type of market doesn't allow resolving some options but not others. It's a feature I'd love them to implement though! There's lots of "what date will X happen" markets that still have 2024 or even 2023 as an option.

@Fion thanks for the quick reply - sorry I didn't know that it wasn't possible.
