# Current state As of mid-August 2026, no "final deal" exists between the U.S. and Iran — the June 17, 2026 MOU's 60-day window expired August 17 with talks stalled/"static," Iran uncommitted to resuming negotiations, and major disputes (uranium stockpile, sanctions relief, Hormuz) unresolved. A UNSC resolution can only occur *after* a final deal is reached, so this market is contingent on two unresolved steps (final deal + Council passage) happening before Dec 31, 2026. # Timeline of key events - 2026-06-17: U.S.-Iran MOU signed (Islamabad framework); Clause 14 states final deal "will be endorsed by a binding UNSC resolution." (confirmed — Axios full text) - 2026-06-23: Reporting details unresolved issues (nuclear inspectors, frozen assets) from first days of talks. (confirmed — Al Jazeera) - 2025-09-19/09-27 (prior year, background precedent): Competing UNSC draft resolutions on Iran sanctions relief both failed to pass; UN sanctions snapped back Sept 27, 2025 — evidence of Council gridlock on Iran. (confirmed — Congress.gov CRS) - 2026-03-11: UNSC Resolution 2817 adopted, condemning Iran's attacks on Gulf states/Jordan — shows Council engaged on conflict, not peace-deal endorsement. (confirmed — Wikipedia/UNSC record) - 2026-08-15/16: Iran FM Araghchi states Tehran has not decided to resume talks and disputes MOU was ever a ceasefire; Iran security leadership reshuffled toward hardline IRGC figure. (reported — CDM, Al Jazeera) - 2026-08-16/17: MOU's 60-day deadline expires without extension or final deal; U.S. side calls negotiations "static." (confirmed — Al Jazeera, CGTN) # Event Will the UNSC adopt a resolution endorsing/implementing a "final" U.S.-Iran deal (per the June 2026 MOU's Clause 14) by Dec 31, 2026? # Outcomes to forecast Yes / No # Kalshi market anchor Kalshi-direct price not returned in tool output; Polymarket (same event, mirrored ticker) shows current price 14.5% YES, down from a 56% high — treat this as the best available consensus anchor given no distinct Kalshi price was retrieved. # Sub-question answers 1. **Current Polymarket price for this ticker?** — 14.5% YES; down 8pts (7d) and 16pts (30d); range has been 14.5%–56% over 57 days; volume $173,460. (Polymarket direct) 2. **Recent news affecting this market?** — MOU's 60-day deadline expired Aug 17, 2026 with no final deal; Iran hasn't committed to resuming talks; disputes remain on uranium stockpile, sanctions, Hormuz; Iran's security apparatus reshuffled toward a tougher posture. (Al Jazeera, CGTN, CDM) 3. **What do related prediction markets imply?** — No direct UNSC-Iran related markets found (0 matches). Adjacent Polymarket markets show Strait of Hormuz traffic NOT normalizing by Aug 31 (99.35% No) or Sept 30 (93.5% No), implying continued regional disruption/tension consistent with stalled diplomacy. (Polymarket related) 4. **Historical base rate for similar events?** — Prior UNSC Iran resolutions in Sept 2025 (both competing drafts) failed to pass, evidencing P5 gridlock even on narrower sanctions-relief questions; base rate for full multilateral "final deal" ratification within a compressed timeframe is low. (Congress.gov CRS) # Key facts (high-confidence, factual) 1. [Axios] MOU Clause 14 explicitly conditions UNSC resolution on existence of a "final deal" — not yet reached. 2. [Al Jazeera/CGTN] 60-day MOU deadline (from June 17) expired Aug 17, 2026 without a final deal or extension. 3. [CDM/Al Jazeera] Iran's FM says no decision made to resume talks; disputes MOU's characterization as ceasefire. 4. [Congress.gov CRS] Sept 2025 UNSC drafts on Iran sanctions relief both failed — demonstrated Council-level gridlock. 5. [Wikipedia] March 2026 UNSC Res. 2817 addressed Iran's attacks on Gulf states, unrelated to a peace/deal endorsement — Council currently focused on conflict management. # Cross-market signals - Kalshi related: no matching markets found (0 results for UNSC/Resolution/Endorsing keywords). - Polymarket (same ticker): 14.5% YES, sharply down from 56% high, negative 7d/30d trend — market pricing declining probability of resolution passing by year-end. - Sportsbook implied: N/A (not applicable to this event type). - Adjacent Polymarket Hormuz markets imply persistent regional tension (>93% "No" on normalization), consistent with stalled broader diplomacy. # Analyst opinions and speculation - Claude_news synthesis: "December 31 deadline appears unlikely absent a rapid diplomatic breakthrough," citing stalled talks, unresolved substance, and Iran's uncommitted posture. - Iran's security reshuffle (ex-IRGC chief now heading Supreme National Security Council) is read as signaling a harder line, reducing near-term deal likelihood. # Directional lean per outcome - **Yes**: Supporting — original MOU commits both sides in principle to eventual UNSC endorsement; formal framework exists. Opposing — MOU lapsed without a final deal, Iran uncommitted to resuming talks, substantive gaps remain (uranium, sanctions, Hormuz), historical UNSC gridlock on Iran (2025), Polymarket pricing collapsing (56%→14.5%). - **No**: Supporting — all of the above negatives plus only ~4.5 months remain until Dec 31 deadline for both a full final deal AND Security Council passage; precedent of failed 2025 UNSC votes. Opposing — none substantive; only counter-signal is the formal MOU obligation still nominally in force. # Gaps / unknowns - No direct Kalshi YES price returned (tool output empty) — relying on Polymarket as proxy anchor. - No confirmation of whether/when talks might resume post-MOU expiration. - Unclear if a narrower/partial deal short of "final deal" could still trigger resolution attempt (ambiguity in resolution criteria). - No P5 (Russia/China/US) position data specifically on a hypothetical future Iran deal resolution. # Calibration anchors - Polymarket current price (proxy anchor): 14.5% YES, trending down. - 2025 precedent: two competing UNSC Iran resolutions both failed to pass — low base rate for Council consensus on Iran issues. - Diplomatic base rate: comprehensive "final" deals following collapsed interim agreements rarely conclude within single-digit months, especially amid escalating regional tension.

1. Both forecasters anchor tightly around the Polymarket 14.5% price and shade only slightly below it (8% and 11%), but neither grapples with the fact that Polymarket itself may be a thin/stale/mispriced proxy (volume only $173,460, no confirmed Kalshi price) — over-reliance on a single cross-platform anchor risks anchoring bias rather than independent evidence synthesis. 2. Neither forecast explicitly addresses the "Gaps/unknowns" point about whether a narrower/partial deal short of "final deal" could still trigger a resolution attempt — this ambiguity in resolution criteria could push probability higher than either estimate if a scaled-down agreement counts, and both treat "final deal" as a hard binary without hedging for this interpretive risk. 3. Both rely on the same 2025 UNSC gridlock precedent as if it's dispositive, but that precedent involved competing sanctions-relief drafts absent any underlying bilateral deal — a scenario where the U.S. and Iran jointly present a negotiated resolution (as Clause 14 implies) is a materially different reference class with potentially higher P5 cooperation, which neither model adjusts for. 4. Neither forecast considers tail-risk upside scenarios such as a sudden geopolitical shock (e.g., escalation forcing rapid de-escalatory diplomacy, leadership change, or third-party mediation breakthrough) that historically can compress "impossible" timelines — the ~4.5 month window is short but not zero-probability for surprise diplomatic sprints, and both estimates (8-11%) may be reasonable but are justified almost entirely by extrapolating current stasis rather than modeling volatility. 5. The two forecasts are very close (8% vs 11%) with largely identical rationales, indicating insufficient independent reasoning — neither explores why the other might be wrong, and both lean on the same negative signals without differentiating uncertainty around Iran's internal political trajectory post-reshuffle (hardline IRGC ascension could cut either way: entrenchment or eventual negotiated retreat under pressure).

10% (68% confidence)

Yes: 10% No: 90%

The market requires two sequential low-probability steps within ~4.5 months: a comprehensive final U.S.-Iran deal (the June 17 MOU's 60-day window already lapsed Aug 17 without extension, with Iran uncommitted to resuming talks and hardliners ascendant) and then UNSC adoption of an endorsing resolution. The Polymarket anchor at 14.5% and its steep decline from 56% is the best consensus signal, and both forecasters reasonably shade below it given the deteriorating trend and the compound nature of the requirement. However, the critique is right that the anchor is thin and cross-platform, that Clause 14 implies a jointly-presented resolution (a friendlier P5 reference class than the failed 2025 competing drafts), and that ambiguity over what counts as a 'final deal' plus tail-risk diplomatic sprints argue against shading too far down. I therefore land at 10% YES — modestly below the market to reflect the confirmed post-deadline stasis, but not as low as 8%, preserving room for surprise breakthrough and interpretive looseness.
