The most likely scenario is a spark in the Middle East, starting from Lebanon. 
The White House is a possibility, but I think East Asia, specifically Taiwan, could also be a likely scenario. 
All possibilities are on the table.

I'd say most likely is some big horrific invasion in the Middle East, but the most fun would be a Biden resignation.

For me, it's also new information, but since there are previous statistics, it makes it interesting and worth keeping an eye on.

I'll give you major props, if something big happens tomorrow. There are lots of possibilities. Either way, I hadn't heard of this before and it's a neat bit of trivia.
