Nominal loss column.
Will use midpoint in case of an estimation.
Movies with limited theatrical releases obviously don't count if they are designed to make their money from streaming.
Vandalizing Wikipedia is allowed but considered unsporting.
Keep in mind that lots of good and great movies bomb. It's happened before and it'll happen again. I think most people who like movies would probably be able to list a bunch of critically panned movies they enjoyed too.
Edit: Meant to let people submit their own answers, but the market still works. Here's a similar market where you can add your own answers:
https://manifold.markets/asmith/which-of-these-will-be-the-biggest
Will that Wikipedia page be the only source used? Or will it just be a comparison of reported budget vs WW gross that we can find? Since from what I can tell, the article hasn't been updated to include any movies from 2023, and it has a pretty high bar for inclusion. So e.g. Lisa Frankenstein could lose money, but there's basically zero chance it gets included in that article with its small budget.
@asmith you should also add an "Other" or "Something not mentioned at market close" answer or similar to cover the case where the biggest bomb isn't a film you listed or anticipated here, or specify that the market would resolve N/A in that situation
EDIT: pinging wrong user
@duck_master Yeah, I meant to select different options but I forgot this time. I'm changing the title of the market and making a second market.
