According to media reports, a 15-point plan was passed on to Iran by the USA, but this has not been fully verified. Apparently, Iran also had a preference to negotiate with Vance and Rubio, but did not officially commit to anything. Either way, as you can see, Iran has higher leverage.
However, the 15-point plan includes a ban on uranium enrichment. Now also note that the stated reason the Trump Admin launched the offensive was enrichment itself. It turns and you get back to what triggered the war, and Iran will definitely not agree to the point. If Trump were to remove that item from the list now, it would be a major strategic defeat, because the strategic goal of stopping uranium enrichment would not even have been achieved. Iran currently has the momentum. Trump is actively looking for an exit, which he knows he cannot actually afford and yet he is trying.
Accordingly, we can assume that the war will continue. It is not for nothing that the 82nd Airborne Division with around 1000 soldiers has now been sent to the Persian Gulf. $IOIL00 (-1.82%) jumped down accordingly. Whether Iran wants to negotiate at all is of course also a question that I would answer with a rather negative answer (leverage).
