Background-

The Doomsday Clock is a design that warns the public about how close we are to destroying our world with dangerous technologies of our own making. It is a metaphor, a reminder of the perils we must address if we are to survive on the planet...

...Since 2008, the Science and Security Board has met twice a year to discuss world events and reset the clock as necessary. Full timeline of the Doomsday Clock is available here.

Market will resolve based on press releases/official statements posted here:

I do not bet on markets I create.
