Market context
The key change in the last 24–48 hours is that Iranian and foreign media have kept treating Mojtaba Khamenei’s continued absence as the baseline, while fresh claims about his whereabouts and health have done little to produce a verified image or video. Reuters reported on 31 March that Russia’s ambassador said he was in Iran but avoiding public appearances for “understandable reasons”, which reinforces the idea that any appearance would likely be tightly controlled rather than spontaneous.[1][6]
For market reading, the comparable cases point to a low-probability event unless there is a deliberate state-media reveal. Reuters, CNN and the Times of Israel have all described a pattern of written statements, broadcasts and staged messaging without a confirmed in-person sighting, and several reports note that even funeral or memorial occasions passed without his appearance.[5][8][12] That matters because the market only resolves Yes on authentic photos or video taken and released inside the window, so archival clips, reused stills or manipulated material would not count.[2][13]
The main catalysts to watch are official Iranian commemorations, major speeches by senior clerics or IRGC-linked events, and any state-media package that abruptly includes live or clearly time-stamped footage. Iranian outlets have previously floated the idea of a first public showing at a memorial service, but without secondary confirmation, and Reuters has also noted that officials continue to describe him as active while remaining out of view.[17][5] If Tehran wants to reset the narrative, the most likely route is a tightly managed television appearance or a brief on-camera address rather than an unscripted public walkabout.[8][16]
Methodology
Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.
Resolution & payout
Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.
Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
