Will Iran withdraw from the NPT before 2027?

- [2026-03-28] Iranian MP Malek Shariati submitted a fast-tracked bill titled "Support for the Nuclear Rights of the Iranian Nation" calling for NPT withdrawal, repeal of JCPOA implementation law, and new international nuclear partnerships; a lawmaker said a fast-tracked bill proposing Iran's exit from the Nuclear Non-Proliferation Treaty and a shift in nuclear policy has been submitted to parliament's legislative body, including withdrawal from the NPT and repeal of a law governing Iran's commitments under the nuclear deal . (https://www.iranintl.com/en/202603281010) - [2026-09-07/09] IAEA Board of Governors referred Iran's nuclear file to the UN Security Council for non-compliance; the IAEA board referred Iran to the UN Security Council for non-compliance in September 2026 . However, with Russia and China opposing the board's decision, it is unlikely that the council will act against Tehran . (https://www.armscontrol.org/act/2026-10/news/iaea-reports-iran-un-security-council) - [2026-09-20/21] Lawmaker Hossein-Ali Haji Deligani announced a "triple-urgency" NPT withdrawal bill (combined with a call to begin nuclear weapons testing) had been submitted with triple urgency to Parliament's Presiding Board seeking the country's withdrawal from the Nuclear Non-Proliferation Treaty (NPT) , requiring Speaker Ghalibaf's approval for an open floor debate. (https://presstv.substack.com/p/iranian-lawmakers-push-for-npt-withdrawal) - [2026-09-27] A member of parliament's National Security Committee, Mohammad Mehdi Shahriari, said the NPT withdrawal measure would likely secure no more than 70 votes, and that leaving the NPT during wartime would effectively mean pursuing a nuclear weapon, something Iran does not intend to do, noting the Supreme National Security Council and Khamenei had previously opposed leaving the treaty . (https://www.iranintl.com/en/202609274971) - [2026-09-28/29] First Deputy Speaker Ali Nikzad confirmed parliament is reviewing the bill but said parliament will consider the bill after it is formally announced and will assess its international implications, adding it would be considered the same day it is announced ; officials stressed no formal withdrawal from the NPT has been announced, and the bill's fate will depend on whether it can secure support beyond the 70 votes described by Shahriari . (https://www.naturalnews.com/2026-09-30-iran-parliament-fast-tracks-bill-withdrawal-npt.html) - [2026-09-29] Foreign Minister Araghchi reiterated Iran's 60% enrichment is for peaceful purposes and complies with the country's obligations under the NPT, adding Iran is ready to discuss a deal on the 60%-enriched uranium but that trust must first be restored — signaling a preference for negotiation over exit. (https://en.iz.ru/en/2175249/2026-09-29/iran-announced-consideration-possible-withdrawal-npt) - [2026-10-01] Parliamentary presiding board spokesman Abbas Goudarzi stated that withdrawal from the NPT and revision of the nuclear doctrine are "fully attainable and easily achievable" , while a US official said Iran's NPT obligations "do not disappear." (https://www.globalsecurity.org/military/ops/iran-war-update.htm) - [2026-10-02] An open-source intelligence/analysis review concluded that the public official record does not establish that Iran has transmitted an Article X withdrawal notification, and as of 2 October 2026 the verified public record does not show that Iran has answered that question by leaving the NPT or ordering the construction of a nuclear weapon , though it noted the political/legal barriers to doing so have thinned. (https://debuglies.com/2026/10/02/irans-npt-threshold-treaty-withdrawal-nuclear-deterrence-and-the-post-attack-security-doctrine/) - [2026-10-02] The Cradle reported that after two rounds of US-Israeli attacks, Iranian lawmakers are pressing for an NPT exit, with the debate now extending to whether a nuclear bomb would deter another attack , indicating continued escalatory pressure but still at the debate stage. (https://alethonews.com/2026/10/02/irans-npt-debate-moves-beyond-parliament/) - [2026-10-01] Separately, US-Iran diplomacy over Hormuz/sanctions continues: the seven-day proposal that Trump rejected on October 1 provided for discussion of regional conflicts and nuclear issues after the strait reopens and the blockade is lifted , with Trump saying he expects an agreement only after the November 3 midterms — meaning any near-term nuclear diplomacy is stalled, which could cut either way on the withdrawal bill's momentum. (https://www.globalsecurity.org/military/ops/iran-war-oprep.htm) - [2026-09-19] A Senate/CRS-style analysis (via Arms Control Association) confirms Article X formally requires a state to give three-month notice of intent to withdraw and submit a statement on the extraordinary events that led to the decision , meaning even if parliament passes the bill and the government formally invokes it, a three-month notice period follows before withdrawal takes legal effect — relevant to the question's "formally notifies" threshold. (https://www.armscontrol.org/act/2026-05/news/iran-threatens-withdraw-npt) BOTTOM LINE: As of October 3, 2026, Iran's parliament has a "triple-urgency" NPT withdrawal bill pending before the Presiding Board/Speaker approval, but it has not been formally introduced for a floor vote, lacks clear majority support (estimated ~70 votes), and top security officials (SNSC, Khamenei) have previously opposed outright withdrawal; no Article X notification has been issued, and even if passed, Article X requires a three-month notice period, making formal withdrawal before the December 31, 2026 deadline a live but currently unrealized possibility. NOT FOUND: No evidence of an actual parliamentary floor vote date being scheduled, no confirmation that Speaker Qalibaf has approved the bill for open-session debate, and no official Iranian government/ministry statement (as opposed to individual lawmakers) committing to Article X withdrawal.

- [2003-01-10] The only historical precedent for NPT withdrawal is North Korea, which announced its exit on January 10, 2003 (effective one day later), after first threatening withdrawal a decade earlier in 1993 and suspending that threat. North Korea announces its withdrawal from the NPT. North Korea initially announced its intent to withdraw from the NPT a decade earlier following suspicions of NPT violations. After holding talks with the United States, North Korea suspended that withdrawal in June 1993, just a day before it would have come into effect. This shows the reference class is extremely small (n=1 completed withdrawal in 56 years) and that a full decade elapsed between first threat and actual exit. - [2023-01-10] Legal analysts note France, in particular, has deemed this decision to be illegal, and has denounced Pyongyang's unfounded use of Article X of the NPT... it was unacceptable for the country to continue to use, after its withdrawal, nuclear capabilities acquired while it was a party to the regime — i.e., the sole precedent is contested as improper/illegitimate, meaning even a "successful" base-rate case was legally disputed. - [2025-06-12] Iran has issued repeated "warning" threats without follow-through: in June 2025 Iran warned it could legally withdraw from the NPT if European signatories to the 2015 nuclear deal proceeded with reinstating UN sanctions, with its UN ambassador reiterating it would take "proportionate responses," including by "starting the process of withdrawal from the NPT in accordance with Article X." Sanctions snapback occurred and Iran still did not withdraw. - [2026-03-28] A fast-track parliamentary bill was introduced by MP Malek Shariati titled "Support for the Nuclear Rights of the Iranian Nation," with three main pillars: withdrawal from the treaty, repeal of the law on implementing the JCPOA, and support for forming new international agreements with partner countries — this bill has stalled for over six months without a floor vote. - [2026-05-01] Arms Control Association reporting confirms the structural hurdle: since Israel and the United States began strikes against Iran Feb. 28, the parliament has not met in person and there is no clarity on when sessions may resume. If the legislation passes parliament, it will still need to be reviewed by the Guardian Council, which has the power to veto it. - [2026-09-28] As of late September 2026, insider vote-counting suggests the bill lacks support: a National Security Committee member said Iran's parliament is unlikely to approve an urgent proposal to withdraw from the NPT, with the measure potentially securing no more than 70 votes... Leaving the NPT during wartime would effectively mean pursuing a nuclear weapon, something Iran does not intend to do. - [2026-09-28] The same source noted top leadership has historically opposed withdrawal: the Supreme National Security Council and Ali Khamenei had previously opposed leaving the treaty, while Supreme Leader Mojtaba Khamenei had also stressed that Iran should refrain from building nuclear weapons. - [2026-09-30] Independent reporting corroborates the bill is stalled and contested: the measure remains a threatened course of action rather than an imminent policy change, and no formal withdrawal has been approved. - [2026-10-02] The most recent reporting (Oct 2, 2026) shows the decision is explicitly conditional on external events, not yet made: Iranian official Rezaei said "After the United States abandoned the post-war Islamabad Memorandum of Understanding, we reached the conclusion that we must change course. We have yet to take a decision on withdrawing from the treaty, because our withdrawal totally depends on Washington's behavior." - [2026-10-01] Even amid escalation (IAEA referral to UN Security Council), official Iranian channels still frame withdrawal as leverage rather than settled policy: Factions in Tehran continue to call for Iran to withdraw from the NPT. A small group of lawmakers submitted a bill to the parliament calling for withdrawal from the NPT in response to the IAEA board's decision to report Iran to the Security Council. - [2025/2026 sibling markets] Prior Polymarket contracts on the identical resolution criteria for earlier deadlines both resolved "No": a "before August [2025]" market and a "in 2025" market both show final outcome No, each trading near 0% going into expiry, despite live Iran-Israel-US conflict and sanctions snapback during their windows — indicating markets have consistently underestimated near-term NPT exit despite escalating rhetoric. BOTTOM LINE: The outside view is stark — only one state (North Korea) has ever withdrawn from the NPT in the treaty's history, that process took roughly a decade from first threat to completion and remains legally disputed, and Iran itself has cycled through NPT-withdrawal threats repeatedly since 2025 (sanctions snapback, war, IAEA referral) without following through, with its own parliament reportedly lacking votes and top leadership (Khamenei, SNSC) historically blocking the move. This reference class strongly favors continued non-withdrawal through the question's deadline. NOT FOUND: No evidence of any formal Article X notification letter to the UN Security Council or depositary states; no confirmed floor vote outcome on the "triple-urgency" bill as of October 2, 2026; no systematic academic study quantifying the base rate of "threatened NPT withdrawals that did not occur" beyond the Iran/North Korea cases found here.

YES means: Iran's government issues a formal written Article X notice to the UN (and depositary states) explicitly declaring its intent to withdraw from the NPT, on or before December 31, 2026. - [2026-09-20] A "triple-urgency" withdrawal bill — the fastest legislative classification in Iran's parliament, reserved for wartime matters — has already been submitted to the Presiding Board, meaning procedurally it requires only Speaker Ghalibaf's sign-off to reach an open floor vote the same day it is announced, i.e., there is no multi-week committee process left once approved. (https://en.mehrnews.com/news/247902/NPT-withdrawal-bill-submitted-to-parliament-presiding-board) - [2026-09-20] Haji Deligani said Iran's Foreign Policy and National Security Committee has drafted "15 proposals" for NPT withdrawal and a comprehensive plan that may be discussed on the floor, showing the exit option is being institutionalized across multiple draft instruments, not just a single fringe bill. (https://www.iranintl.com/en/202509284755) - [2026-10-02] SNSC Secretary Mohsen Rezaei — the senior security official who would actually have to authorize any withdrawal — publicly confirmed "we reached the conclusion that we must change course" after the US abandoned the post-war Islamabad MoU, and stated withdrawal "totally depends on Washington's behavior," making the decision explicitly conditional and primed to flip quickly if US-Iran diplomacy collapses (negotiations are currently stalled, with Trump saying he expects a deal only after the Nov. 3 midterms). (https://alethonews.com/2026/10/02/irans-npt-debate-moves-beyond-parliament/) - [2026-10-02] A group of lawmakers has escalated beyond the parliamentary bill itself, issuing an open statement directly demanding that the Supreme National Security Council and Foreign Ministry begin the formal Article X withdrawal process and end voluntary nuclear commitments beyond treaty obligations — moving the ask from "pass a law" to "start the diplomatic notification now." (https://alethonews.com/2026/10/02/irans-npt-debate-moves-beyond-parliament/) - [2026-10-02] The same reporting cites a precedent mechanism for how a parliamentary bill becomes binding state policy even against the sitting government's preference: the 2020 Strategic Action Law to Lift Sanctions was a parliamentary initiative that "sharply constrained the Rouhani administration's room for maneuver" over the JCPOA — showing Iran's system has a working pathway for hardline legislators to force the executive's hand on nuclear policy. (https://alethonews.com/2026/10/02/irans-npt-debate-moves-beyond-parliament/) - [2026-10-02] Even Khorasan, a newspaper aligned with Speaker Ghalibaf that has criticized the withdrawal push as "a gift to Trump," does not rule out eventual exit — its position is that Iran should first build and test a weapon before leaving, meaning the gatekeeping camp disputes sequencing/timing, not the end goal itself. (https://alethonews.com/2026/10/02/irans-npt-debate-moves-beyond-parliament/) - [2026-10-02] MP Mohsen Sani argued that because a fellow NPT member (the US/Israel) attacked Iran twice, continued NPT membership "no longer has any meaning," reflecting a legal/political rationale inside parliament's own National Security Commission that could be invoked as the "extraordinary events" justification required under Article X. (https://alethonews.com/2026/10/02/irans-npt-debate-moves-beyond-parliament/) - [2026-09-08] The underlying trigger-trend is intensifying, not easing: the IAEA Board of Governors referred Iran to the UN Security Council on a 23-3 vote (Russia, China, Niger opposed), which Iranian lawmakers have directly cited as the proximate justification for the withdrawal push, and any further UNSC action (even if blocked by Russia/China) would hand hardliners a fresh "extraordinary event" to invoke. (https://kayhan.ir/en/news/153920/iranian-lawmakers-seek-npt-withdrawal) - [2026-09-29] Deputy Speaker Nikzad confirmed the bill, once finalized, is slated for an "exceptional-urgency" plenary procedure requiring same-day consideration — meaning if Ghalibaf releases it to the floor, formal passage could occur within a single legislative session, compressing the YES timeline considerably versus ordinary Majlis procedure. (https://caliber.az/en/post/iranian-parliament-prepares-bill-to-quit-nuclear-non-proliferation-treaty) BOTTOM LINE: The clearest path to YES is a rapid chain — collapse or further deterioration of US-Iran diplomacy (plausible given Trump's post-midterm timeline and the stalled Oct 1 seven-day proposal), which the SNSC secretary has already said would be the trigger — combined with Ghalibaf releasing the triple-urgency bill for a same-day floor vote and the SNSC/Khamenei's office (rather than Khamenei personally, who is deceased per Oct 2 reporting referencing Mojtaba Khamenei as Supreme Leader) approving it, all of which the Sept–Oct 2026 record shows is mechanically ready to move fast once the political green light is given, even though it has not yet been given. NOT FOUND: No confirmation of a scheduled floor-vote date; no statement from Ghalibaf himself on when/whether he will release the bill; no official SNSC vote or Guardian Council action on any version of the bill.

YES means: Iran's government issues a formal written Article X notice to the UN explicitly announcing withdrawal from the NPT, on or before December 31, 2026, 11:59 PM ET. - [2020-01-28] This is not Iran's first "snapback-triggered" withdrawal motion: a near-identical bill was submitted to parliament after the E3 triggered JCPOA's dispute mechanism in January 2020, with lawmaker Mahmoud Sadeqi noting it was unclear when it would even be debated and that it would still need Guardian Council vetting — that motion never became law, establishing a second (pre-2025) Iran-specific precedent of threat-without-follow-through beyond the single North Korea case. (https://www.globalsecurity.org/wmd/library/news/iran/2020/iran-200128-presstv01.htm) - [2026-09-27] President Pezeshkian stated explicitly and on the record, in New York, that "we do not want to withdraw from the NPT" and that Iran does not intend to leave the treaty even if UN sanctions are reinstated — the clearest executive-branch rejection of withdrawal to date, directly contradicting the hardliner bill's premise. (https://wanaen.com/pezeshkian-we-have-no-intention-of-leaving-the-npt/) - [2026-09-25] Pezeshkian told Fox News he would give up 60%-enriched uranium "within the framework of international law, based on the Nonproliferation Treaty," and his UN speech drew praise even from Speaker Ghalibaf, judiciary chief and Expediency Council chairman — showing the institutional center of gravity, including Ghalibaf personally, currently aligns with a conciliatory NPT-compliant posture rather than withdrawal. (https://www.iranintl.com/en/202609257671) - [2026-10-02] Khorasan, a newspaper close to Speaker Ghalibaf, publicly criticized the withdrawal-pushing lawmakers for "radicalizing the political ambiance of the country" and called the move "a gift to Trump" — direct evidence the Speaker's own camp is working against fast-tracking the bill, even as lawmakers (Ghazanfari) blame the presidium for keeping it off the floor "for months." (https://alethonews.com/2026/10/02/irans-npt-debate-moves-beyond-parliament/) - [2026-09-29] Deputy Speaker Ali Nikzad confirmed the bill is still only "being studied," with no floor date set, and that it would need to be brought to a plenary session "marked as extremely important" only once formally announced — procedurally this remains pre-introduction, not pre-vote. (https://1news.az/en/news/20260929091505414-Iran-s-parliament-to-consider-draft-withdrawal-from-the-NPT-on-an-urgent-basis) - [2026-09-12/14] Even as hardliner Haji-Deligani pushed the bill, Pezeshkian reiterated to Indian media that "if we were seeking nuclear weapons, we would not have joined the NPT" — a consistent two-week pattern of presidential statements rejecting withdrawal even as the parliamentary track continued. (https://www.globalsecurity.org/wmd/library/news/iran/2026/09/iran-260913-rferl02.htm) - [legal structure] Historical and current reporting confirms a two-stage veto gate even if the floor vote succeeds: any passed bill "will still need to be reviewed by the Guardian Council, which has the power to veto it," before implementation — a body that has in the past slowed or blocked similarly urgent nuclear legislation. (https://www.armscontrol.org/act/2026-05/news/iran-threatens-withdraw-npt) - [2026-09-02, historical] Foreign Ministry spokesman Baghaei's framing that withdrawal is "the prerogative of parliament" (not the executive) suggests that even if parliament passed a bill, implementation/notification would then depend on the Pezeshkian government and SNSC actually transmitting the Article X notice — bodies that have been the most consistent internal voice against withdrawal. (https://en.mehrnews.com/news/236051/Withdrawal-from-NPT-is-prerogative-of-Iranian-parliament) BOTTOM LINE: Beyond the previously documented ~70-vote shortfall and SNSC/Khamenei-era opposition, two further structural facts cut toward NO: (1) a near-identical "snapback-triggered" NPT withdrawal motion was submitted in January 2020 and quietly died without passage, giving Iran its own prior false-alarm precedent independent of North Korea; and (2) President Pezeshkian has, as recently as September 25–27, 2026, repeatedly and explicitly disavowed withdrawal even under sanctions reinstatement, while Speaker Ghalibaf's allied press has publicly attacked the withdrawal push — meaning the two actors who would need to move the bill forward (Speaker) and ultimately transmit any Article X notice (President/government) are currently the most visible internal brakes on the measure. NOT FOUND: No confirmed Guardian Council review schedule for the bill; no statement from interim Supreme Leader authority (Mojtaba Khamenei or Interim Leadership Council) explicitly blessing or blocking withdrawal since the February 2026 assassination of Ali Khamenei; no official Iranian notification letter or depositary-state confirmation of any Article X filing as of October 3, 2026.
