# Current state
Ali Khamenei was killed in a US-Israeli strike on 2026-02-28; Iran's Assembly of Experts elected his son Mojtaba as the new supreme leader on 2026-03-08/09 with IRGC backing, and key institutions (armed forces, President Pezeshkian) publicly pledged loyalty. Mojtaba formally holds the position today, but has not appeared verifiably in public since the war began, was reportedly wounded in the strike, skipped his father's July funeral, and only a brief ~15-second undated video (Aug 10, 2026) has been released — leaving his health/whereabouts genuinely uncertain even though no institutional actor has moved to replace him.

# Outcomes to forecast
Yes / No
# Kalshi market anchor
No Kalshi-direct price for this specific ticker was returned in research (kalshi_related found no matching Iran/Khamenei/Supreme Leader market for this event). Best cross-market anchor is **Polymarket: 82.6% YES**, down 0.1% over 7 days, up 2.85% over 30 days, range 68.35%–85.10% over 91 days, $6.15M volume — indicating steady, high conviction with a modest upward drift as Mojtaba's position has consolidated institutionally despite his public absence.
# Sub-question answers
1. **Polymarket price/trend** — 82.6% currently; +2.85% over 30 days, -0.1% over 7 days; traded in a 68.35–85.10% band over 91 days, suggesting the market priced in succession risk early and has since converged toward high confidence in Mojtaba's continued hold. [polymarket_direct]
2. **Sibling outcomes** — No sibling market data was returned (polymarket_related and kalshi_related found no other Iran-leader contracts), so implied P(Ali Khamenei remains)/Pezeshkian/other cannot be decomposed from market data; note Ali Khamenei is already deceased (Feb 2026), making "Ali Khamenei remaining" moot.
3. **Baseline mortality/removal risk** — This sub-question's actuarial framing (pre-death Khamenei, 86-87yo) is now moot: Ali Khamenei was already killed 2026-02-28 [Wikipedia]. The code_execution model (5.9% central "Mojtaba becomes HoS" estimate) was built on outdated priors and does not reflect that the succession has already occurred and been institutionally ratified.
4. **Succession shortlist/rivals** — Mojtaba was selected by the 88-member Assembly of Experts (2026-03-08/09) over other reported contenders (no strong evidence Hassan Khomeini or Alireza Arafi were seriously considered in the final IRGC-backed process); Mojtaba has close ties to IRGC chief Ahmad Vahidi and Parliament Speaker Ghalibaf. [JPost]
5. **Conditional on installation, will he actually exercise authority?** — Institutions (IRGC, armed forces, presidency) have pledged loyalty and no rival power center has emerged publicly; however, his total public absence since March 2026 and unverified health raise open questions about whether he is personally exercising authority vs. a IRGC/clerical council governing in his name. [JPost, RFE/RL]
6. **Renewed strikes/destabilization risk** — Iran remains in active war/high-tension state through August 2026 (ongoing JPost live updates, Hezbollah-related rhetoric from Mojtaba in July); Israel previously struck Assembly of Experts HQ and killed the prior supreme leader, showing demonstrated willingness/capability to target leadership — meaningful tail risk to Mojtaba's survival/authority persists. [Wikipedia, Al-Monitor]
# Key facts (high-confidence, factual)
1. [Wikipedia] Ali Khamenei killed 2026-02-28 in US-Israeli strike; 36-year tenure ended.
2. [JPost/Al Jazeera] Mojtaba Khamenei elected third supreme leader by Assembly of Experts, 2026-03-08/09.
3. [Al Jazeera] IRGC, armed forces, and President Pezeshkian publicly backed Mojtaba's appointment.
4. [Wikipedia] Mojtaba was wounded in the strike that killed his father, mother, wife, and a sister.
5. [JPost, RFE/RL] Mojtaba has had no confirmed public appearance since March 2026; skipped father's July funeral; only an undated, unverifiable ~15-second video released Aug 10, 2026.
6. [Wikipedia] UN officially lists Iran's president, not the supreme leader, as de jure head of state — but this market's resolution criteria explicitly use a de facto control standard, favoring the supreme leader/Mojtaba framing.
# Cross-market signals
- Kalshi related: no directly comparable Iran leadership market found; unrelated "leader leaves office" markets (Merz, Tshisekedi) show no read-through.
- Polymarket: 82.6% YES, stable/slightly rising — strong majority consensus Mojtaba retains de facto power through year-end.
- Sportsbook implied: none available (not applicable to this event type).
# Analyst opinions and speculation
- Atlantic Council: Mojtaba viewed as more hardline than his father with ties to extremist clerics, suggesting IRGC/hardline continuity rather than a moderate pivot.
- Media speculation (JPost, Israel National News) questions whether Mojtaba is alive, in Iran, or capable of governing, given total lack of verified imagery; some suggest a caretaker/IRGC council could be running the state in his name.
- Iranian officials insist he is alive and performing duties, promising future images — an unconfirmed claim given the pattern of unverifiable releases.
# Directional lean per outcome
- **Yes**: Formal Assembly of Experts installation, institutional loyalty pledges (IRGC, military, presidency), no announced successor or rival claimant, five-plus months of unchallenged nominal rule, Polymarket at 82.6% and rising.
- **No**: Total absence of verified public appearance for ~6 months, unresolved health status/possible incapacitation, functioning could be exercised by an IRGC/clerical collective rather than Mojtaba personally, ongoing war raises assassination/destabilization risk before Dec 2026.
# Gaps / unknowns
- No Kalshi-direct YES price was retrieved for this specific ticker — cannot confirm the actual "consensus to beat" price on Kalshi itself.
- No independent verification of Mojtaba's health/location beyond Iranian state media claims.
- No detail on whether an IRGC council or Pezeshkian is exercising actual day-to-day authority versus Mojtaba personally, which is central to the market's de facto-control resolution standard.
- The code_execution actuarial analysis is stale/inapplicable given confirmed events postdating its assumptions.
# Calibration anchors
- Polymarket YES price: 82.6% (primary available cross-market anchor; Kalshi's own price not retrieved).
- Precedent: 1989 Khomeini-to-Khamenei succession saw rapid Assembly of Experts action and durable consolidation despite Khamenei's initially weak clerical credentials — supports base-rate expectation that an Assembly-anointed successor with IRGC backing tends to persist absent overt challenge.
