Prediction markets put the probability at 48%: Iran agrees to end enrichment of uranium by December 31. Currently, markets are divided (48% YES, 52% NO). Iran's strongest card in nuclear talks: its highly enriched uranium.
Iran and the United States are negotiating an extension of their post-June ceasefire to begin formal talks on Tehran's nuclear program, with the disposition of Iran's 440.9 kilograms of 60% enriched uranium identified as the first agenda item. Washington insists Iran must not retain the capacity to build a nuclear weapon, while a draft US proposal would allow Tehran to keep its existing stockpile only if diluted to 3.6% reactor-grade material — a step the International Atomic Energy Agency describes as moving the inventory away from the 90% threshold associated with weaponization. The negotiations follow the June 2026 Israeli and US strikes that destroyed much of Iran's enrichment infrastructure but left the highly enriched stockpile intact. [Reuters, May 29]
The question of whether Iran agrees to end enrichment of uranium by December 31 remains unresolved as President Donald Trump requested several amendments to the draft US-Iran memorandum of understanding, according to a senior administration official cited by Axios on May 30. The Institute for the Study of War reported that Trump specifically sought changes to text governing how and when Washington would secure the highly enriched uranium, leaving the two sides at odds on verification timelines. The interim agreement — brokered after Pakistani Army Chief Asim Munir visited Tehran — ended fighting across Lebanon, reopened the Strait of Hormuz, released some frozen Iranian assets, and granted limited oil-sale waivers, but deferred resolution on enrichment itself.

Republican hardliners have publicly broken with the administration, arguing any deal that permits Iran to retain enriched material — even diluted — falls short of the dismantlement standard Washington previously demanded. Analysts caution that converting 440 kg to reactor-grade fuel is technically reversible and that IAEA verification access remains a sticking point. Whether Iran agrees to end enrichment of uranium by December 31 will hinge on three structural factors: Trump's final position on the MoU amendments, Supreme Leader Ali Khamenei's acceptance of dilution versus export, and the durability of the ceasefire framework that made talks possible. The MoU drafting process is the operative timeline to watch. [Times of Israel, May 30]

6 of 7 models estimate YES fair value above market (56–86c vs 57c). Kimi Macro leads with 75% confidence.
Models estimate fair value of YES at 70c — market prices it at 57c. 13-point gap supports YES.
Smart money is exclusively long YES, with entries clustered in a tight 52-58c band that reads as deliberate accumulation rather than momentum chasing. The absence of NO positioning from tracked wallets signals directional conviction that Iran concedes enrichment, though the shallow 2-wallet sample and breakeven P&L mean this is a thesis being built, not yet validated.
| Wallet | Category | Side | Amount | P&L | |

Tracked YES holders entered at 52-58c against the current 57c mark, leaving only half in profit and the cohort hovering near breakeven. With no NO exposure on the book and YES P&L pinned to entry, price support is fragile — a dip below 55c would flip the profitable half underwater and remove the only conviction anchor.
Polymarket prices YES at 46c with $474K in total volume. Our model estimates fair value at 70c. Significant 24-point gap — model sees YES as substantially mispriced.
