There is an unconfirmed claim that the US agreed to some asset unfreezing during/in preparation for the talks in Islamabad: https://www.timesofisrael.com/liveblog_entry/us-agrees-to-release-frozen-iranian-assets-in-qatar-foreign-banks-to-ensure-opening-of-hormuz-senior-iranian-source/

Resolves YES if by the close date any senior official confirms on the record that such an agreement was made. This is regardless of whether such agreement is then honored or ends up being confirmed, it is sufficient that the US delegation or some of its representatives agreed. The value of the assets in question is also irrelevant, it just need to be assets that were previously frozen due to sanctions.

Market resolves only based on public confirmations by the US side. If there are reasons to believe the agreement was made, but it is not publicly confirmed by market close, this still resolves NO.

If there are doubts about the specific timing of the confirmation (e.g. some delay between an official making that statement and the statement being reported) or if the official in question is "senior", I will tend to resolve YES.

I will not bet on this market.
