Will Saudi airspace be closed by October 31?

- [2026-10-12] Saudi airspace (Jeddah FIR, OEJD) is still technically open, with no FIR-wide closure found. SafeAirspace says it "remains technically open" but rates it Level 1, "Do Not Fly". The closures found so far are at individual airports. https://safeairspace.net/saudi-arabia/ - [2026-10-12] Riyadh's King Khalid International (OERK) is closed until 21:00 UTC on 17 Oct (NOTAM A3604/26). GACA gave no reopening date and said it was checking facility safety. That is an airport closure, not a closure of the FIR. https://www.airwaysmag.com/new-post/faa-saudi-airspace-warning-riyadh-airport-closure - [2026-10-10/11] A Houthi missile attack on Riyadh airport on 10 Oct killed 13 and wounded more than 300. A second strike hit Terminal 4 on 11 Oct. Dammam's King Fahd airport (DMM) was also attacked on the evening of 11 Oct, and inspections are under way. https://www.abc.net.au/news/2026-10-11/houthi-airport-attack-saudi-arabia-riyadh-closure/107253872 - [2026-10-11] The Houthis warned all airlines to avoid Saudi airports and airspace. They exempted the Mecca and Medina airports. This is a non-government warning and does not qualify under exclusion (ix). https://www.durangoherald.com/articles/associated-press/saudi-arabia-extends-closure-of-airport-after-12-killed-in-suspected-houthi-missile-attack/ - [2026-10-11] FAA NOTAM KICZ A0056/26, valid to 10 Dec, tells US operators to exercise caution across the Jeddah FIR at all altitudes. It is not a prohibition, and it is a foreign notice rather than a Saudi order. https://safeairspace.net/saudi-arabia/ - [2026-10-09] EASA CZIB 2026-09-R1, valid to 16 Nov, says to avoid two sectors of the FIR (southeast and northwest) and to use caution elsewhere. Its text says Saudi Arabia has managed its airspace through tactical deconfliction and ESCAT. https://safeairspace.net/saudi-arabia/ - [2026-10-08] Canada's NOTAM F5624/26, valid to 23 Oct, recommends Canadian operators not enter the Jeddah FIR. France's notice (valid to 14 Oct) says most of the FIR should be avoided, with exceptions for routes in the north and west at or above FL320. Both are foreign advisories. https://safeairspace.net/saudi-arabia/ - [2026-10-08] ch-aviation, relayed via Wego, reports NOTAM-based closures at Jazan and Najran (round the clock) and Abha (nightly 18:00–06:00 Saudi time) until 15 Oct. These are airport-level closures. https://blog.wego.com/saudi-arabia-airspace-flights-status-affected-airlines-what-travelers-need-to-know/ - [2026-10-12] Cirium data via The National shows 46.4% of scheduled Saudi flights cancelled as of 12:00 UTC. Lufthansa cancelled Riyadh flights until 16 Oct, and Air France-KLM suspended Riyadh service through the end of October. Delta postponed its 23 Oct Atlanta–Riyadh launch to March 2027. https://www.airwaysmag.com/new-post/faa-saudi-airspace-warning-riyadh-airport-closure - [2026-10-12] Wego rates the Jeddah airport as disrupted, with "no verified airport-wide closure". It says Etihad listed Jeddah cancellations for 12–13 Oct. https://blog.wego.com/saudi-arabia-airspace-flights-status-affected-airlines-what-travelers-need-to-know/ - [2026-09-28] The wider US/Israel–Iran war has run since 28 Feb 2026. On that day Qatar, Kuwait, the UAE, Bahrain, Iraq and Iran closed their airspace, but Saudi Arabia was not among them. As of 28 Sep there was no ceasefire, and one report says Trump expects to resume bombing after the November midterms. https://iranwarlive.com/airspace BOTTOM LINE: The trend is escalating, with Houthi strikes on Saudi airports and Riyadh closed to at least 17 Oct. Even so, Saudi authorities have kept the FIR open and have only closed individual airports, which exclusion (vii) does not count. A qualifying Saudi-issued general suspension would need a further sharp escalation, and none had been issued as of 12 Oct. NOT FOUND: I found no GACA or SANS NOTAM closing the whole Jeddah FIR. I could not open the GACA or SANS sites directly. I also found no scheduled event before 31 Oct that would force a closure.

- [2026-10-12] Saudi airspace (Jeddah FIR) is still technically open. Safeairspace/OPSGROUP says it "remains technically open" but rates it Level 1 "Do Not Fly". The cause is Houthi missile and drone attacks, including on Riyadh, Abha, Jazan and Najran. https://safeairspace.net/saudi-arabia/ - [2026-10-12] Only a single airport is closed, not the FIR. GACA extended the Riyadh (RUH) suspension, which a NOTAM runs to Oct 17 (reported by Siasat and Safeairspace). Aviation Week says GACA gave no resumption date. Jeddah and Dammam have heavy cancellations but no airport-wide closure verified. Closing one airport is a subset closure and is excluded by clause (vii). https://aviationweek.com/air-transport/airports-networks/saudi-airport-attacks-trigger-cancellations-airspace-warnings - [2026-10-12] The attack tempo is rising. A strike on Oct 10 killed 13 and wounded over 300 at RUH. Another on Oct 11 killed 1 and injured 11, and Dammam was also attacked. The Houthis told airlines to avoid Saudi airports and airspace, except Mecca and Medina. https://www.abc.net.au/news/2026-10-11/houthi-airport-attack-saudi-arabia-riyadh-closure/107253872 - [2026-10-12] Foreign advisories are not Saudi closures, and clause (ix) excludes them. EASA CZIB 2026-09-R1 (Oct 9, valid to Nov 16) says avoid two defined parts of the FIR and take caution in the rest. Canada recommends not entering the FIR (to Oct 23). France restricts most of it. The FAA advises caution only (to Dec 10). https://safeairspace.net/saudi-arabia/ - [2026-10-12] Saudi Arabia's own long-running tool is ESCAT, a regional or short-notice tactical restriction. The Saudi NOTAM OEJD W0120/21 has applied since 2021 to the southern FIR. It was in force before market creation and is regional, so it would not count. https://safeairspace.net/saudi-arabia/ - [2026-02-28] Base rate for Gulf neighbours: Qatar, Kuwait, the UAE and Bahrain closed their airspace when the US-Israel strikes on Iran began. The Wego/Wikipedia/Universal Weather items in my search results describe Saudi Arabia as open (restricted) throughout the 2026 war, including the June 2026 renewed strikes. No Saudi FIR-wide closure turned up in my searches. https://www.thenationalnews.com/business/aviation/2026/02/28/airlines-suspend-flights-amid-us-israel-strikes-on-iran-and-gulf-airspace-closures/ - [2026-06-04] Wego summary of the Iran strikes of 2–3 June: Kuwait and Bahrain were closed or limited, while Saudi Arabia was "Open, restricted" (EASA caution, not below FL320). That supports a pattern of Saudi staying open when neighbours closed. https://blog.wego.com/which-countries-have-reopened-airspace-after-the-us-iran-ceasefire/ - [2026-05] Saudi Arabia briefly suspended US military aircraft use of its airspace and Prince Sultan Air Base. The restrictions were lifted by May 7. That was a nationality-based restriction, which clause (vi) excludes. https://polymarket.com/event/saudi-arabia-bans-us-military-aircraft-by - [2017-2021 precedent] Saudi Arabia has historically blocked specific flows rather than shutting its FIR. It closed Yemen-bound routes in 2017 and barred Qatari flights from 2017. During 2020–22 Houthi attacks it applied ESCAT in the south rather than closing the FIR. These are the only precedents I found, and none was a general FIR closure. https://en.wikipedia.org/wiki/Sanaa_International_Airport - [2026-10-09/10] Other venues: the Polymarket sibling "Saudi airspace closed by December 31" showed about 8%, 14% and 22% in different page snapshots, with schema data dated Oct 9–10. Another page showed 26% about 21 days ago. These are the December 31 sibling, not this contract, and snapshots are stale and inconsistent. https://polymarket.com/predictions/saudi - [2026-10-12] Houthi attacks are concentrated on airports and on Riyadh, which hosts the energy congress. Saudi Arabia's visible response so far is airport-level suspensions. Airlines still planned over 7,700 departures from 28 Saudi airports for the week of Oct 12. https://aviationweek.com/air-transport/airports-networks/saudi-airport-attacks-trigger-cancellations-airspace-warnings BOTTOM LINE: Historically, Saudi Arabia has not closed its whole FIR, even when Gulf neighbours did in February and June 2026 and through the 2017–22 Houthi campaigns. It relies on airport-level closures and ESCAT, and clauses (vii) and (ix) exclude both of these and foreign advisories. The risk is now elevated: the attacks are escalating and there is a Level 1 warning. The reference class still points to a low base rate, with a tail risk of a general suspension. NOT FOUND: Any Saudi (GACA/SANS) NOTAM suspending commercial flights across the whole Jeddah FIR. Any official Saudi statement on a nationwide closure. A track record for these Polymarket airspace markets. The exact price of this Oct 31 contract (deliberately not sought).

YES means: between 2026-09-20 and 11:59 PM ET on 2026-10-31, GACA, SANS or another Saudi authority issues a NOTAM or order that takes effect and suspends commercial flights by default across the whole Jeddah FIR (OEJD). Airport-only closures, ESCAT in a sector, and foreign advisories do not count. - [2026-10-11] Saudi Arabia says it will "firmly" retaliate, and the Houthis renewed their attack on Riyadh the next day. Al Jazeera reports the Oct 10 strike was the deadliest on the kingdom in over a decade. Trump says the US "may" join the strikes, and Turkiye, Pakistan and Saudi Arabia on Oct 5 agreed to activate "deterrence measures" under their mutual defence pact. This points to a widening war rather than de-escalation. https://www.aljazeera.com/news/2026/10/11/yemen-fighting-expands-as-houthis-attack-saudi-airport-what-to-know - [2026-10-11] The Houthis hit more than airports. Per the same Al Jazeera article, they claim a strike on the Aramco refinery at Rabigh, on the Red Sea coast near Jeddah, and a missile was shot down heading for al-Kharj. A Dammam projectile on Oct 10 means the east is also exposed. EASA names Tabuk, Medina and Yanbu as areas already struck. Attacks are now nationwide, which weakens any argument for a sector-only response. https://www.aljazeera.com/news/2026/10/11/yemen-fighting-expands-as-houthis-attack-saudi-airport-what-to-know - [2026-10-12] Safeairspace's September entry says Jeddah airport "closed at short notice" during an air-defence response. The Saudi authorities have therefore already shut the Red Sea hub, not just southern airports. A repeat of that, combined with the Riyadh closure, would leave the two biggest hubs shut. Separately, Safeairspace's Aug 26 note says three southern airports were already closed. https://safeairspace.net/saudi-arabia/ - [2026-10-12] Mechanism: Saudi Arabia's published procedure is ESCAT, which hands control of civil traffic to the military. EASA says the Saudi operating environment is "vulnerable to rapid deterioration". Canada's travel advice says Saudi airspace "could close at any time with little or no warning." A countrywide ESCAT with a default ban on civil flights would be the quickest route to a qualifying order, and it could be issued at once. Whether it counts depends on wording: a full-FIR default suspension would count, a regional ESCAT would not. https://travel.gc.ca/destinations/saudi-arabia - [2026-10-09] Reuters says the Houthis "tried to shut down" Saudi airspace. They want a de facto closure through threats against airlines. If carriers withdraw wholesale, Saudi authorities might formalise a closure, though this is inference rather than a reported plan. https://www.usnews.com/news/world/articles/2026-10-09/houthi-strikes-on-riyadh-airport-killed-three-saudis-as-war-escalates - [2026-10-12] The foreign advisory ladder has risen sharply in a week. Safeairspace raised the rating to Level 1 on Oct 9. Canada's NOTAM (to Oct 23) says do not enter the FIR at any level. Germany's NOTAM runs to Nov 10 and EASA's to Nov 16, so these warnings cover the whole window. This does not itself resolve the market, but the next step up would be a Saudi decision to stop flights. https://safeairspace.net/saudi-arabia/ - [2026-10-04] The Saudi-backed "Dawn of Yemen" offensive began Oct 4, with a claimed 100 jets and 324 targets hit on day one. The collapse of the 2022 ceasefire and the Houthi blockade-retaliation cycle since July (CNN) mean Saudi fighter and air-defence activity will stay heavy over the kingdom through October. Heavy military activity is the usual trigger for a civil airspace suspension. https://www.cnn.com/2026/10/04/middleeast/yemen-offensive-houthis-intl - [2026-10-12] Resolution looseness: "consensus of credible reporting" could be satisfied by headlines such as "Saudi shuts airspace". Riyadh and Dammam are the two largest hubs, and an OERK closure to Oct 17 could be extended. Riyadh plus Dammam plus the southern airports closed together could be reported as a general closure even without an FIR-wide NOTAM. The criteria nonetheless exclude subset closures, so this path is weaker. https://safeairspace.net/saudi-arabia/ - [2026-10-12] Sibling market snapshots on cryptobriefing, undated but citing the Houthi strikes, put the by-Oct-31 contract near 8% to 8.5%, and the by-Dec-31 contract at about 19.5%. These are stale snapshots from the sibling contracts, not this one. They show the market treating a closure as possible but not likely. https://cryptobriefing.com/houthis-claim-strikes-on-riyadh-airport-warn-airlines-to-avoid-saudi-airspace BOTTOM LINE: The strongest YES path is a further Houthi mass strike, or a US/Iran-linked escalation, that prompts GACA/SANS to issue a countrywide ESCAT or a default suspension of civil flights. Prerequisites are attacks on Jeddah or the Red Sea corridor, or several hubs closed at once, plus Riyadh's closure being extended past Oct 17. So far Saudi authorities have only closed airports and kept the FIR open, so this is a tail path. NOT FOUND: Any GACA or SANS NOTAM closing the whole FIR, or any Saudi statement signalling one. Also not found: the text of Saudi NOTAM A3604/26 beyond the Oct 17 date, whether Jeddah (OEJN) is currently closed, and any Saudi statement on ESCAT being activated countrywide. The US News/Reuters page could not be fetched in full, so its content comes from the search snippet.

YES means: Saudi Arabia's aviation authority (GACA/SANS) issues a NOTAM or order that takes effect between Sept 20 and Oct 31, 2026 and bars commercial flights by default across the whole Jeddah FIR (OEJD). Airport-only, sector-only, foreign-advisory and Houthi-issued closures do not count. - [2026-10-12] AP, citing two regional officials, reports Riyadh is investigating how its air defences failed. Officials said the Houthi drones and missiles flew more than 1,000 km undetected. AP also says the Saudis kept the World Petroleum Congress running in Riyadh and that Riyadh airport stayed closed. The government is projecting business as usual and has not shut the sky. https://www.pbs.org/newshour/world/saudis-probe-how-defense-systems-failed-to-stop-deadly-houthi-attack-on-riyadh-airport - [2026-10-12] Saudi Energy Minister Abdul Aziz bin Salman said the "response must be equally serious". AP says Riyadh wants deeper US involvement in countering the Houthis. The stated response is military and diplomatic, not aviation shutdown. A US strike on the Houthis would be a possible escalator, but AP notes Trump faces midterm pressure against widening the war. Iran has offered to mediate, and Araghchi spoke with the Saudi foreign minister on Oct 11. https://www.pbs.org/newshour/world/saudis-probe-how-defense-systems-failed-to-stop-deadly-houthi-attack-on-riyadh-airport - [2026-10-09] After the Oct 8 strikes, GACA said Riyadh operations had resumed and traffic was back to normal, within about a day. The authority's pattern is short airport suspensions followed by reopening. It is not a move toward a FIR-wide shutdown. https://www.aljazeera.com/news/2026/10/9/saudi-arabia-reopens-riyadh-airport-after-houthi-attack-kills-three - [2026-10-12] New Arab says Jeddah's King Abdulaziz airport "remains open". IBTimes (Oct 12) lists Jeddah, Dubai, Abu Dhabi and Doha as open, with Riyadh the lone suspended hub. Closing the west-coast hub would be a precondition for a FIR-wide closure, and it has not happened. https://newarab.com/analysis/which-airlines-have-cancelled-saudi-flights-amid-houthi-attacks - [2026-10-12] Wego says Saudi Arabia "has not announced a nationwide airspace closure". It describes Jeddah as having no verified official closure. Among the sources I found, none reports a GACA/SANS general suspension. https://blog.wego.com/is-riyadh-airport-open-live-status-2026/ - [2026-10-06] OPSGROUP, whose newest Middle East update I fetched, says Saudi "remains open" with heavy overflight traffic. The Jeddah FIR is the main southern Europe–Asia bypass, with Kuwait closed to overflights until Nov 2. ATC congestion in the FIR is reported. Closing it would sever the region's key transit corridor, which gives Saudi a strong economic and diplomatic reason to avoid it. OPSGROUP expects ESCAT to be activated at short notice, which is a tactical restriction and not a closure. https://ops.group/blog/middle-east-airspace-current-operational-picture/ - [2026-09-30] EASA's own text (CZIB-2026-09-R1) tells operators to be prepared for short-notice instructions from state authorities, and to avoid only two defined sectors. Even Europe's strictest regulator stops short of treating the whole FIR as closed. Any sector-based Saudi NOTAM falls under exclusion (vii). https://www.easa.europa.eu/en/domains/air-operations/czibs/czib-2026-09-r1 - [2026-09-30] Migflug's read of the EASA bulletin states plainly that Saudi Arabia "has not closed anything", with Saudia still flying and the FIR busy. https://migflug.com/afterburner/easa-czib-2026-09-saudi-arabia-jeddah-fir-airspace-warning/ - [2026-09-19 to 2026-10-12] The Houthi campaign has run since at least Sept 19, with a fuel-storage fire at Riyadh airport. Through the Sept 26 and Oct 1 interceptions, the Oct 6 strikes on Jazan and Najran, and Oct 8–12 attacks on Riyadh, Dammam and Khamis Mushait, Saudi Arabia never closed its FIR. Roughly three weeks of escalating attacks have produced only airport-level closures. The question window already includes this escalation, and it has not triggered a closure. The Houthi naval blockade began in July. https://www.euronews.com/2026/09/26/saudi-coalition-says-it-intercepted-houthi-drones-and-missiles-bound-for-saudi-arabia - [2026-10-12] Resolution mechanics favour NO. The FIR-wide closure must be a Saudi-issued order that bans commercial flights by default. Houthi warnings, EASA, FAA, Canadian and French notices, and single-airport closures are all excluded by clauses (vii) and (ix). Many Saudi partial measures, such as ESCAT and nightly Abha closures, predate or fall short of the criteria. Ambiguous press headlines like "Saudi airspace closed" would need to be backed by an actual GACA NOTAM, and none has surfaced. https://safeairspace.net/saudi-arabia/ - [2026-10-12] Saudi Arabia is the Houthis' target. It has about 100 aircraft supporting the Yemen offensive and a US advisory presence. A full closure would also halt its own air operations and Hajj/Umrah and Saudia traffic. The airspace is a military asset in an active offensive, which argues against shutting it. https://en.wikipedia.org/wiki/2026_Yemen_offensives BOTTOM LINE: Eight months of Iran-war attacks and three weeks of escalating Houthi strikes have produced only airport-level and sector restrictions. Riyadh is projecting normalcy, and the FIR is a critical bypass and military asset, so the status quo is NO, and a literal reading of the criteria excludes most plausible partial closures. A YES would need a new, unprecedented Saudi general suspension within 19 days. NOT FOUND: Any GACA or SANS NOTAM closing the whole Jeddah FIR. Any Saudi statement considering a nationwide closure. Direct access to the GACA and SANS sites, which I did not open. A prior Saudi FIR-wide closure in the 2017–22 Houthi campaigns or the 2026 Iran war.
