Private Superforecasting Workshop and erikbays ask:
Before 1 January 2022, will the U.S. officially rejoin the JCPOA?
Obstacles standing in the way of the U.S. rejoining the Joint Comprehensive Plan of Action (JCPOA) include the issues of current U.S. sanctions against Iran and Iran's resumed production of highly enriched uranium (Atlantic Council, BBC, Washington Post, Federation of American Scientists).
NOTE 14 June 2021: The US rejoining the JCPOA under revised terms would count.
The question closed "No" with a closing date of 1 January 2022.
