It included this: Will we ever see another significant protest calling for a 6 month pause on AI development of frontier models? Highly doubt it.

Resolves YES if there is such a protest, or there is indeed such a pause. If it is a protest, it must call for either an indefinite or 6+ month pause. If it is an actual pause, it must last 6 months or be in place on the resolution date, and must include the most advanced AI labs (either 3+ most advanced, or all those within striking distance of the leader). 

An open letter signed by people who combine to be more prominent than the original pause letter (since the original wording said 'another') would automatically count as significant.

If this market gets sufficient participation I will consider operationalizing 'significant' more carefully. For now, it is roughly 'is a for-real protest and gets covered as such with substantial visibility by at least 3 mainstream media outlets.'
