Market Trust diligence packet
Iran closes its airspace by May 18?
One-screen answer to a buyer's question: can this market price be cited, used with caveats, discounted, or ignored? The packet separates the verdict from evidence confidence, source freshness, participant quality, integrity screens, and receipts.
So what?
Monitor, but do not cite as current. The evidence is useful as an archived read until the data freshness window refreshes.
Freshness gate: Diligence packet is stale for current product claims. Treat this as archived evidence and wait for a refresh before demos or outreach.
Memo language
Convexly rates this polymarket market "Iran closes its airspace by May 18?" as Do not cite. Use only as a review target. Current-card issues must clear before this price is used as evidence. Caveat to carry: Too much participant flow is unknown while participant-quality evidence is still pending. This is market diligence, not a trading instruction or proof that the market probability is correct.

How it adds up: composite = Σ(score × weight) / Σ(weight) across measured + heuristic pillars only. Pending and data-rights-blocked pillars are excluded from both numerator and denominator. Total contributing weight = 70.0.
Caveat: 2 pillars pending — the score will recompute as the substrate fills in.

Resolution rule
This market will resolve to “Yes” if Iran initiates a major closure of its airspace, that is not solely due to weather conditions, by the listed date, 11:59 PM ET. Otherwise, this market will resolve to “No”. A “major closure” is defined as a broad closure, cancellation, or suspension of commercial flights transiting, arriving in, and departing from Iranian airspace or a major Iranian Airspace region. A qualifying closure must apply generally to flights across Iran or a major Iranian airspace region. Limited cancellations, delays, or other partial closures will not qualify. Limited exceptions to a broad closure, however, will not disqualify such a closure from counting (e.g. exceptions for certain flights pre-approved by the Iranian Civil Aviation Authority may be permitted). Any non-weather complete suspension of commercial arrivals and departures affecting at least two of the following airports will qualify: Imam Khomeini International Airport (IKA), Mehrabad Airport (THR), Mashhad International Airport (MHD), Shiraz International Airport (SYZ), or Isfahan International Airport (IFN). Qualifying previous examples include the January 2026 total closure of Iranian airspace except to international flights with express governmental permission (https://www.reuters.com/world/middle-east/iran-shuts-airspace-most-flights-flightradar24-says-2026-01-14/) and the April 2024 closure of Iran’s western airspace (https://www.reuters.com/world/middle-east/iranian-airports-cancel-flights-until-monday-morning-2024-04-14/). Non-qualifying examples include the January 27, 2026 partial closure of Iranian airspace around the Strait of Hormuz (https://www.aa.com.tr/en/middle-east/iran-issues-airspace-notice-for-military-drills-near-strait-of-hormuz/3812508) and the January 25 - April 25, 2026 VFR (Visual Flight Rules) flights suspension which did not broadly close commercial aviation in a qualifying region (https://www.intellinews.com/iran-suspends-general-aviation-and-vfr-flights-in-new-airspace-directive-421997/). Warnings, No-Fly-Zones, or other flight restrictions imposed by airlines or countries other than Iran will not be sufficient for a “Yes” resolution. Airspace closures which occur solely due to weather conditions will not qualify. The primary resolution sources for this market will be official information from Iranian aviation authorities and a consensus of credible reporting.

Public v1 promotion
4 public v1 validation gates still open.
Canary readiness says the current batch can be reviewed. Public v1 promotion waits for coverage, clean source-health windows, resolved outcomes, and formula-freeze evidence.
Read the promotion evidence contract- Not enough pillars on this card are measured yet.
- Some pillars on this card are still gathering evidence.
- 14 consecutive clean source-health days have not yet been observed.
- 30 current cards across 3 market categories are not yet reached.
- The scoring formula must be frozen before validation runs.
- At least one resolved-outcome row is still needed in the validation ledger.

Boundary of the packet
This packet is market diligence, not investment advice, not a claim of absolute truth, and not proof that any trader should buy or sell. It answers whether the market price has enough substrate to cite, monitor, discount, or ignore with receipts attached.
