US-Iran ceasefire continues through the midterms?

Context: the formal June ceasefire collapsed in July. The US is now in a de facto lull, with no US strikes on Iranian territory reported in recent days. Trump has publicly pledged no attack before Nov 3. - [2026-07-08/09] Trump declared the ceasefire "over" after Iranian attacks on shipping. The US said it hit about 90 Iranian targets, and Iran retaliated against Gulf states. Talks continued. https://www.nbcnews.com/world/iran/us-iran-new-attacks-trump-ceasefire-over-gulf-hormuz-rcna353615 - [2026-07-17] A Pakistan-brokered conditional two-week ceasefire was reported, but Iran later suspended its commitments. A Polymarket page summarising the news says prices fell on Iranian statements on Jul 31. https://polymarket.com/event/us-x-iran-effective-ceasfire-byptptpt-2-week-pause-20260715194822042 - [2026-09-02] The IRGC said it struck US positions in Jordan, Bahrain and Iraq "in response to US attacks". So US strikes occurred in early September, and the truce was already fragile. https://en.wikipedia.org/wiki/2026_Iranian_strikes_on_Arab_countries - [2026-09-26/27] Trump rejected Iran's seven-point proposal. It would lift the US blockade, reopen Hormuz within 7 days, and include a ceasefire covering Lebanon. He said he is "always thinking" about resuming strikes. https://thehill.com/policy/international/6114543-donald-trump-us-iran-war-peace-talks/ - [2026-09-29 to 10-02] Indirect talks via Qatar and Pakistan continued. Iran said it received a US response around Oct 1. The sides reportedly largely agree on the steps but disagree on their order. https://www.theglobeandmail.com/world/article-us-responds-to-iranian-ceasefire-proposal-as-washington-pulls-out-of/ - [2026-10-08] Trump said US forces will not attack Iran before the Nov 3 midterms. He has also said the conflict "is going to end immediately after the elections" and that more bombing after the vote may be "possible". https://www.aljazeera.com/news/2026/10/15/us-iran-stalemate-what-are-trumps-next-military-options - [2026-10-13] WSJ reported Iran is fortifying nuclear sites and preparing for possible US strikes after the midterms. CNBC repeats Trump's pledge. https://www.cnbc.com/2026/10/13/iran-us-war-houthis-saudi-arabia-airport.html - [2026-10-13/14] GlobalSecurity's day-229 update says no US or Israeli strike on Iranian territory was reported on Oct 13–14. A tanker was struck in Hormuz and Brent was near $106. I could not fetch the page, so this comes from the search snippet. https://www.globalsecurity.org/military/ops/iran-war-oprep.htm - [2026-10-12/13] A US fighter jet struck and disabled a commercial vessel that had left an Iranian port in the Gulf of Oman. This is at sea, not Iranian territory, and the US blockade continues. Iran says its talks with the US via mediators continue. https://www.cbsnews.com/live-updates/iran-war-us-trump-saudi-arabia-houthi/ - [2026-10-15] Al Jazeera describes the situation as "deadlocked". Iranian attacks on ships are at their highest since the war began: UKMTO recorded 15 attacks between Oct 6 and 14. At least three US carrier groups are in or heading to the region, and the USS Theodore Roosevelt is en route. https://www.aljazeera.com/news/2026/10/15/us-iran-stalemate-what-are-trumps-next-military-options - [2026-10-15/16] A Polymarket page summary claims Trump extended the ceasefire indefinitely on Oct 15 and that a 60-day interim accord was reached. Neither claim is confirmed in the fetched Al Jazeera or CNBC pieces, which describe a deadlock, so treat them as unverified. https://polymarket.com/event/us-iran-ceasefire-continues-through-the-midterms - [2026-10-16] Sibling Polymarket markets (as of Oct 16): the "US-Iran ceasefire continues through" market is at Yes 97% for Oct 17, 95% for Oct 18 and 89% for Oct 22. https://rg.org/news/prediction-markets/polymarket-daily-brazil-runoff-lula-bolsonaro-fed-hike-world-series-october-16-2026 - [2026-10-15] An earlier snapshot of the sibling markets had the ceasefire at 80% through Oct 31, 57% through Nov 15 and 42% through Nov 30. Traders treat the post-election period as the main risk. https://www.coinspeaker.com/us-iran-polymarket-odds-contract/ BOTTOM LINE: The US is holding fire on Iranian territory under Trump's explicit pre-election pledge, while the blockade, Iranian ship attacks and Houthi escalation continue. The main risks before Nov 3 are a "self-defense" strike after an Iranian attack, or a Trump reversal. The forces and planning point to resumption after the vote. NOT FOUND: Any confirmed US air or missile strike on Iranian territory in Oct 1–16. Official confirmation of an "indefinite extension" or 60-day accord. Any scheduled talks or deadlines falling before Nov 3. The full GlobalSecurity page.

I could not find the date of the last US strike on Iranian soil. I fetched pages from CBS and Wikipedia, but the Wikipedia pages were mostly truncated. The Oct 13–14 GlobalSecurity update reports no US or Israeli strike on Iranian territory on 13–14 Oct. Resolution turns on whether a US air or surface-to-surface strike hits Iranian land between now and Nov 3. - [2026-10-08] Trump said the US would not attack Iran before the midterms. He also cited "productive conversations" with Iran, without specifics. CBS notes Pezeshkian called the talks "meaningless" and that talks appear to be at an impasse. This is a verbal pledge, not a signed commitment. https://www.cbsnews.com/live-updates/iran-war-nuclear-donald-trump-vance-rubio-strait-of-hormuz/ - [2026-10-12/13] Trump was asked whether the Houthi strike on Riyadh's airport would change his no-strike pledge and answered "we're gonna take a look". He also said he may consider joining the Saudi-led campaign against the Houthis in Yemen. That would be strikes in Yemen, not Iran, so it would not count. https://www.cbsnews.com/live-updates/iran-war-us-trump-saudi-arabia-houthi/ - [2026-10-14] GlobalSecurity (day 229) reports no American or Israeli strike on Iranian territory on 13–14 Oct and says the 8 Oct pledge stands. It also reports Trump suggesting Iran may be behind the Houthi attacks to raise oil prices before the midterms. I could not open the page, so this comes from the search snippet only. https://www.globalsecurity.org/military/ops/iran-war-oprep.htm - [2026-10-13] The US naval blockade of Iranian ports continues, and Iran still targets ships in Hormuz. The UK maritime agency reported 2 vessels hit by projectiles on Oct 13. Hormuz friction is the trigger that produced US strikes in May and July. https://www.cbsnews.com/live-updates/iran-war-us-trump-saudi-arabia-houthi/ - [2026-10-12] Iran says it is still reviewing the US response to its 7-day ceasefire proposal, and indirect talks continue through mediators. https://www.cbsnews.com/live-updates/iran-war-us-trump-saudi-arabia-houthi/ - [2026-09-26] Trump rejected Iran's 7-day ceasefire proposal as unacceptable but said talks remain on the table. The date is inferred from the "18 days ago" age tag. https://thehill.com/policy/international/6114543-donald-trump-us-iran-war-peace-talks/ - [2026-04-08 to 07-08] Reference class: the first US–Iran ceasefire began Apr 8 and was violated repeatedly. A CRS report dated May 13 says fighting was intermittent from May 4 and the truce was on "life support". The US also struck Iran in "self-defense" in the seventh week (late May). https://www.congress.gov/crs-product/IN12678 - [2026-05-26 approx.] The US carried out limited "defensive" strikes on Iranian military targets near Hormuz during the ceasefire, after IRGC missile, drone and boat launches. This shows the US struck Iran within a nominal ceasefire. The date is inferred from the "seven-week pause" wording. https://www.nbcnews.com/world/iran/us-military-says-conducted-self-defense-strikes-targets-iran-rcna346839 - [2026-06-25 to 07-10] After the mid-June MOU, Iran's ship attacks drew US strikes on Jun 25–26. On Jul 7–9 the US hit about 80 and then about 90 targets, and Trump declared the ceasefire "over" while saying talks would continue. Each US strike followed an Iranian attack on shipping, with a lag of one day or less. https://abcnews.com/Politics/us-iran-ceasefire-mou-broke-timeline/story?id=134622392 - [2026-08-16] Al Jazeera reported the MOU's 60-day window expiring, and Araghchi said there was "no 60-day ceasefire" to extend. Since early July the arrangement has been informal. https://www.aljazeera.com/news/2026/8/16/us-iran-mou-is-set-to-expire-what-to-know - [2026-09 (CRS)] CRS says US–Iran confrontations continued as of September 2026. Israel and Iran last exchanged fire on Jun 7–8. https://www.congress.gov/crs-product/R48887 - [2025-06-24 to 2026-02-28] Older reference class: the Twelve-Day War ceasefire held about 8 months before the US and Israel resumed bombing on Feb 28. Trump has paired peace talk with strikes before. https://en.wikipedia.org/wiki/Twelve-Day_War_ceasefire BOTTOM LINE: Since April the US has struck Iran during ceasefires several times (late May, late June, early July), usually within a day of an Iranian attack on shipping. Counting against that, Trump's explicit pledge to stand down until Nov 3 and a lull in US strikes on Iran in recent days make a US-initiated strike on Iranian soil in the next 18 days less likely than the earlier pattern implies. Ongoing Hormuz attacks and Houthi/Saudi escalation remain the plausible triggers. NOT FOUND: the date of the most recent US strike on Iranian territory. Also not found: any independent expert estimate or poll on the ceasefire holding through Nov 3, and a text of the pledge beyond the news summary. I did not look for this contract's own price.

YES means: the US conducts no qualifying air or surface-to-surface missile strike that hits Iranian land (internal waters included) by 11:59 PM ET on Nov 3, 2026. The market resolves "Yes" if no such strike happens. - [2026-10-08] Trump's Truth Social pledge was unqualified: "we will not be attacking Iran at any time prior to the Midterm Elections." It came with a statement that the blockade stays in force and that talks are "productive". The White House repeated it on Oct 13 while denying that Trump and Netanyahu discussed resuming the war. https://thehill.com/homenews/administration/6136781-trump-vows-no-iran-attack/ - [2026-10-08] The political incentive is on record. CNN reports Trump appears reluctant to restart an unpopular war before the midterms, and officials know flare-ups lift oil prices and hurt Republicans on cost of living. Officials said he had not fully ruled out strikes until the Oct 8 post, so the post was a deliberate narrowing of options. https://www.cnn.com/2026/10/08/politics/trump-iran-attack-election - [2026-10-13] Axios, from two US officials, an Israeli official and a fourth source, says most of Trump's advisers favor keeping up economic pressure. A US official is quoted: "this economic choking is working better and better." Only Hegseth and CENTCOM leadership are described as the strongest backers of resuming strikes. Trump "has been going back and forth", but an Israeli official says he grew more hesitant. https://www.axios.com/2026/10/13/netanyahu-trump-iran-war-elections - [2026-10-13] Axios says "Go ahead and get ready" to Netanyahu was "no commitment". It also reports that the IDF chief told the Joint Chiefs a restart could force a postponement of Israel's Oct 27 election. That is an extra brake on a joint operation before Nov 3. The same piece says the planning is "maybe now, maybe later, maybe never". https://www.axios.com/2026/10/13/netanyahu-trump-iran-war-elections - [2026-10-13/14] Iran ran its heaviest shipping attacks of the war between Oct 5 and 14 and drew no US strike on land. Iran International cites a UANI expert saying Tehran is "testing" the pledge and that the lack of retaliation is encouraging it. The same article says 12 vessels were hit between Oct 5 and 11, plus two more on Oct 13. This is the best evidence the pledge is holding under stress. It also differs from the earlier pattern, in which a shipping attack drew a strike within a day. https://www.iranintl.com/en/202610139692 - [2026-10-13] The US is substituting non-kinetic tools. Treasury sanctioned 17 shadow-fleet vessels on Oct 8, and Kpler shows zero Iranian crude loadings in September, the first such month since 1979. The IMF projects Iran's GDP at -7.6% in 2026. Washington is also weighing easing restrictions on "legal oil" tankers (Fox, Oct 15–16). These steps fit a strategy of waiting out the election, not escalating before it. https://www.iranintl.com/en/202610139692 - [2026-10-12] Diplomacy is nominally live. Iran's foreign ministry says it is reviewing US proposals and messages are passing via Pakistan and Qatar. Qatar said the same on Oct 6–7. TASS says the US signalled after Jul 8 that it was shifting from large-scale force to economic strangulation. https://tass.com/world/2200777 - [2026-10-13] Iran is deterring through widening. WSJ, via Iran International, reports Tehran warned regional governments that renewed US strikes would bring a wider response, including a possible move into neighbouring states. That raises the cost to Washington of a limited "self-defense" strike before the election. https://www.iranintl.com/en/202610132727 - [2026-09-01/02] The last confirmed US strikes on Iranian soil that I found were Sept 1–2, with CENTCOM wrapping up that night. NPR called the preceding period a "monthlong lull". That is a second precedent for long gaps with no US strikes on land, from early August to Sept 1. By Oct 16 the gap since the last strike is roughly six weeks. https://www.npr.org/2026/09/02/nx-s1-5954013/us-iran-war-latest-updates - [2026-10-12/13] US kinetic activity is being directed at sea and at Houthi-related targets. Only land strikes in Iran count, and naval gunfire and strikes on ships do not. Trump's possible joining of the Saudi anti-Houthi campaign would not count either. This leaves the US a way to answer Iran-linked escalation without touching the contract's trigger. https://www.iranintl.com/en/202610139692 BOTTOM LINE: The strongest Yes path is simple: Trump keeps the Oct 8 pledge through Nov 3 and uses the blockade, sanctions and sea-based enforcement in place of land strikes. Advisers, midterm oil-price politics, Israel's Oct 27 election and live mediation all favor that, and the pledge has already survived the highest tempo of Iranian ship attacks of the war. Prerequisites: no US service-member mass-casualty event, and no Iranian strike on a Gulf state or US base that forces a "defensive" response. NOT FOUND: Any US strike on Iranian land after Sept 2. The indefinite extension or 60-day accord claimed by the Polymarket summary: this is unconfirmed. Any scheduled talks or deadlines before Nov 3. A text of any written commitment beyond Trump's post.

YES means: no US air strike or surface-to-surface missile strike (including one-way attack drones) hits Iranian land territory through Nov 3, 2026, 11:59 PM ET. A US strike on Iranian land resolves NO. - [2026-10-16] The Critical Threats Project said "No ceasefire is in force". The only thing holding is a unilateral US pause, which has no text, no verification and no mediator guarantee. It is not a truce. The Oct 15 CTP-ISW update recorded no strikes, but nothing legally binds Washington or Tehran. The market asks only whether one qualifying US strike lands. https://williamusher.substack.com/p/iran-war-executive-update-october - [2026-10-15] Trump named a target on the record in a Newsmax interview: Pickaxe Mountain, the tunnel complex near Natanz. He said "We may have to go there… We'll knock it out fast" and that the war "will be over very soon". This is a new, specific signal, one week after the Oct 8 pledge. A strike on a named hardened site would be an air strike on Iranian land. https://williamusher.substack.com/p/iran-war-executive-update-october - [2026-10-15/16] ABC reported that officials have prepared options for Trump, including the MOAB. CNN first reported the MOAB plans. Trump has "not made a decision". The options menu is being refreshed after the Oct 8 pledge, not shelved. https://abcnews.com/International/live-updates/iran-live-updates-trump-us-attack-iran-ahead/?id=137063637 - [2026-10-07/08] The Atlantic reported the White House asked for strike options executable before Nov 3. It tied this to Trump's wish to show progress and to lower gasoline prices. The Pentagon asked CENTCOM to "conclude preparations" for resuming major combat. The Oct 8 pledge came the next day, after these leaks. https://www.jpost.com/middle-east/iran-news/article-910974 - [2026-10-08 → 2026-10-14] The pledge has an escape hatch in practice. A White House official says Trump "has all options available at any time". Trump on Oct 14 said "leakers should be shot" over reports of pre-midterm strike plans, rather than denying the plans. He has a record of denying decisions already made: on Feb 27 he said he had not decided on the war, which began within 24 hours. https://www.axios.com/2026/10/08/trump-iran-strikes-midterm-elections - [2026-10-13] Axios reported that Netanyahu and Trump discussed a joint US-Israeli operation against military and nuclear sites. The White House called the report "false". The Israeli election on Oct 27 is the other date that could trigger action. Ynet sources say the IDF is at short-notice readiness but Netanyahu is "unenthusiastic" before the vote. The Axios page returned a 403, so this rests on the search snippet. https://www.axios.com/2026/10/13/netanyahu-trump-iran-war-elections - [2026-10-16] UKMTO counted 12 attacks on ships near Iran in the past week. Hormuz transits are about 70% below pre-war levels. The US has said it will respond to such attacks, and Iranian attacks on ships are the trigger behind every earlier US strike series. https://www.iranintl.com/en/liveblog/202610105959 - [2026-10-15] CENTCOM said an Iranian projectile sank the container ship GFS Pride, and a second vessel, Cape Dao, is confirmed sunk. Sinkings are escalations beyond mere harassment. The US said it destroyed an Iranian-affiliated dhow on Oct 6 and disabled a vessel on Oct 12–13, so it is using force at sea while claiming restraint. Those at-sea actions do not count under this market. https://redstate.com/nick-arama/2026/10/14/centcom-iran-ship-hit-n2208144 - [2026-09-01 and after] Past US restraint has not lasted. CENTCOM struck on Sept 1, Iran struck at US positions in Jordan and Bahrain, and a month-long pause had ended on Aug 30. iranwarlive says no US strike on Iranian territory has been reported since Sept 8. That is about 38 days of quiet as of Oct 16, so the pause is not unprecedented in length. Another 18 days is shorter than a month-long pause that has already ended once. https://iranwarlive.com/ - [2026-10-16] Iran's acting oil minister said Tehran will retaliate at "the right time" against threats to energy plants. Pezeshkian called talks futile. Iran's envoy says US ultimatums "will not produce results". The two sides' positions are hardening, so no deal is in sight that would remove the strike trigger before Nov 3. https://www.aljazeera.com/news/liveblog/2026/10/16/iran-war-live-saudi-blasts-houthi-war-crimes-us-warns-on-saudi-airports - [2026-10-16] Resolution technicalities favour NO. Any single US strike counts, however small, as long as it is an air strike or surface-to-surface strike on land. This includes "self-defense" or "limited" strikes, such as the May 7 "love tap" exchange that Trump said left the ceasefire in effect. The 3-day window for conflicting reports can extend past Nov 3, and Iranian state media claims of US strikes feed the dispute rules. Strikes on coastal sites such as Larak Island or Hormuz installations count as terrestrial territory. Strikes at sea, at vessels, on dhows, or by naval gunfire do not count. https://en.wikipedia.org/wiki/7_May_2026_United_States_strikes_on_Iran BOTTOM LINE: The case for NO rests on three things: a pledge with no enforcement mechanism, a prepared strike list with a named target (Pickaxe Mountain), and daily Iranian ship attacks. Under those conditions a single "self-defense" strike would resolve the market. Counting against NO, the last US strike on Iranian land was about 38 days ago, and the Oct 8 pledge was made publicly and repeated by the White House on Oct 13. NOT FOUND: Any confirmed US strike on Iranian land from Oct 1 to 16. A text or deadline for any binding truce. Any official confirmation of the "indefinite extension" or 60-day accord. The full Axios Oct 13 article, because the page returned a 403. A primary CTP-ISW page.
