Some thoughts on criteria:

A plane tragedy is now "the headline story" on CNN. However, there is still a "Live Update" section available, so presumably this does not yet resolve? ("and/or" wording a bit fuzzy)

I have have an older market with that resolves from the print version of the LA Times on specific future days.

Slightly different criteria but similar intent (capturing how long major protests will last in some objective way)

I won't bet in my own market, but I will bet here. This market's 27% June 15 and 50% June 20 seems to overestimating how quickly this will resolve (the national guard and marines are unlikely to quickly turn around and disappear from Los Angelenos' lives, and there are larger protests scheduled over the weekend, which could continue).

Thanks for making this one.

@Anonculously I’ll say no, it doesn’t count.
