The Trump administration and Iranian President Masoud Pezeshkian's government have signed a memorandum of understanding, according to sources familiar with the agreement. The MOU outlines U.S. concessions linked to specific pressure points, including the Strait of Hormuz and ending the war in Lebanon, and references a Feb. 28 attack on Iran. The deal arrives as bettors on the prediction market Polymarket lowered the odds of Iran ending its uranium enrichment to 61.5%, a shift that reflects uncertainty about the agreement's impact.
Why the MOU matters
The MOU marks a rare formal step between Washington and Tehran after years of indirect talks and backchannel communications. By tying U.S. concessions to issues like the Strait of Hormuz — a critical chokepoint for global oil shipments — and the ongoing conflict in Lebanon, the agreement signals a transactional approach. The Feb. 28 attack mentioned in the document remains unspecified, but its inclusion suggests a timeline or trigger for compliance. Analysts following the region note that the MOU does not directly address Iran's nuclear program, though the Polymarket odds indicate traders see a lower chance of enrichment ending.
What the MOU covers
Under the MOU, the United States has agreed to certain concessions in exchange for Iranian actions on two fronts. First, the Strait of Hormuz: a long-standing flashpoint where Iran has threatened to disrupt shipping. Second, the Lebanon war — likely a reference to the conflict involving Hezbollah and Israel. The exact scope of the concessions is not public, but the linkage suggests the Trump administration is using leverage on these issues to extract Iranian commitments. The document's mention of a Feb. 28 attack adds a temporal element, possibly a deadline or a retaliatory event tied to the agreement's implementation.
Market odds shift
Polymarket, a platform where users bet on real-world outcomes, has reduced the probability of Iran ending its uranium enrichment from earlier levels to 61.5%. The drop came after news of the MOU broke, indicating that traders view the deal as a step that might delay or alter Iran's nuclear activities without guaranteeing a full halt. The 61.5% figure leaves room for doubt — a reflection of the MOU's narrow focus on security and regional conflicts rather than enrichment itself. Whether the odds continue to fall or rebound will depend on the Feb. 28 attack and how both sides follow through on their promises.
Unresolved questions
The MOU leaves key details unanswered. What exactly is the Feb. 28 attack, and who carries it out? How will the concessions on the Strait of Hormuz and Lebanon be verified? And most critically, does this deal move Iran closer to ending enrichment, or does it simply trade one set of tensions for another? The Polymarket numbers suggest the market is skeptical. With no official statements from either capital, the next concrete step will likely come as Feb. 28 approaches — or if the odds on Polymarket shift again.
