Democrats broadly agree the announcement is positive

Social justice/culture war (excluding immigration)

Broad initiative combining multiple unrelated subjects

Manifold agrees that it is indeed "very, very big", "as big as it gets", "one of the most important announcements that have been made in many years about a certain subject" etc.

The US is joining The Dominion of Canada to get around Chinese tariffs

Nuclear weapons/energy/other nuclear policy

He will declare himself the “real” pope

Unless otherwise implied, a topic here only applies to the announcement itself, and not related future policy. 

Multiple topics can resolve YES at the same time. Some topics are supersets of others, e.g. "Foreign Policy" and "Tariffs."

An invasion of a foreign nation would resolve "Foreign Policy" 

 "Military" YES. It would also resolve "Tariffs" YES if that invasion caused new tariffs 

announced at the same time as the invasion

If by May 20 Trump makes no announcement that is unambiguously the one he referred to on May 6, market settles YES to "Trump makes no announcement by May 20" and NO to everything dependent on him actually making an announcement. (Announcement doesn't need to be made by Trump himself, just by the administration.)

Another nation joining the Abraham Accords would settle "Gaza/Israel conflict" to YES.
