About This Event
On June 14, 2026, the United States and Iran announced a written diplomatic agreement, including a 60-day extendable period in which both countries committed to negotiate toward a “final deal” regarding Iran’s nuclear program and other topics. This market resolves to “Yes” if a qualifying written diplomatic instrument between the United States and Iran has been mutually signed or adopted by the specified date, 11:59 PM ET. Otherwise, this market resolves to “No.” Unless the written instrument is formally adopted without signature as described below, the instrument must be signed by both the United States and Iran. Both parties must either sign the same document or sign individual documents that substantively and directly indicate acceptance of the same underlying instrument, regardless of minor formatting, wording, or translation differences between the signed versions. Both physical signatures and officially-issued electronic signatures will qualify as signatures. If the written instrument is recognized by the United States and Iran as not requiring signature for execution, formal adoption of the instrument by both countries without signature will qualify. Formal adoption may be established by official actions, including: (i) an official joint statement announcing that the United States and Iran have adopted, approved, executed, concluded, or otherwise finalized the instrument; (ii) mutual official confirmation that the same published instrument has been agreed to, adopted, approved, executed, or concluded by both countries; (iii) adoption, approval, or endorsement through an official resolution, ministerial decision, executive decision, or equivalent institutional act, where that act is the mechanism by which the relevant country adopts the instrument; or (iv) an exchange of official diplomatic notes or letters confirming acceptance of the same instrument. A qualifying written diplomatic instrument must: (i) Be identified as the final deal contemplated by the June 14, 2026, memorandum of understanding, either in official United States or Iranian communications, or by a consensus of credible reporting; (ii) Establish at least one specific obligation limiting Iran's nuclear program through a concrete, measurable benchmark against which compliance could be tested, which may take the form of a defined limit, prohibition, or quantity (e.g., a specific cap on the purity level to which Iran may enrich uranium, or an explicit commitment for Iran to surrender, destroy, or dilute its enriched uranium stockpile). Non-specific or vague restrictions, with no defined metric (e.g., a pledge not to pursue nuclear weapons, a commitment to maintain the status quo, or an agreement to abide IAEA monitoring or inspections requirements that do not specifically restrict Iran’s nuclear program) will not qualify. The content of the qualifying instrument must be expressed as an agreed obligation to be implemented. The following do not qualify: (i) a provision the substantive obligation of which remains explicitly subject to a future agreement, negotiation process, or mutually agreed follow-on instrument; (ii) a provision explicitly framed as a minimum requirement for a future negotiation, rather than a present obligation; (iii) a floor, placeholder, or minimum standard established explicitly for the purpose of structuring ongoing or future talks. A definite and unconditional obligation may qualify, even if technical or procedural details, including the exact implementation date, timeframe, or sequencing, remain subject to future arrangements, provided that the obligation still establishes a concrete, measurable benchmark against which compliance could be tested. Conditional obligations do not qualify. Whether an instrument qualifies will be primarily determined by its officially released text. A qualifying instrument must be signed or formally adopted by both the United States and Iran by the specified date, 11:59 PM ET. If such an instrument is signed or formally adopted by that time, but the complete text has not been released, and genuine material ambiguity remains as to whether it satisfies this market’s requirements, this market may remain open for up to 28 calendar days after the specified date pending release of the text. If the text has still not been released after 28 calendar days, official and definitive announcements from the United States or Iran, and a consensus of credible reporting, will be used to determine whether the instrument qualifies. An instrument to which parties other than the United States and Iran are also party will qualify, provided that both the United States and Iran are parties to the instrument and all other requirements are satisfied. Once a diplomatic instrument has been signed or formally adopted without signature by both the United States and Iran and confirmed to satisfy the requirements of a qualifying written diplomatic instrument, this market’s condition is met, regardless of whether the instrument later enters into force, is ratified, receives legislative or treaty consent, or is subsequently repudiated, withdrawn from, or not implemented by the United States or Iran. The primary resolution sources for this market will be official communications from the governments of the United States and Iran, or their authorized representatives. A consensus of credible reporting from major news agencies of record may also be used.

What the contract measures
The saved event asks whether a contract resolves to "Yes" if "a qualifying written diplomatic instrument between the United States and Iran has been mutually signed or adopted by the specified date, 11:59 PM ET," and to "No" otherwise [1]. The source describes a June 14, 2026 announcement of a written diplomatic agreement that included "a 60-day extendable period" for negotiating toward a "final deal" on Iran's nuclear program [1]. This is the source's background description. The snapshot does not show the current status of those negotiations.
Three contracts share this event, each with a different deadline: December 31, 2026, November 30, 2026, and October 31, 2026. Their listed end times are 2027-01-01T04:59:00.000Z, 2026-12-01T04:59:00.000Z, and 2026-11-01T03:59:00.000Z [1]. The listed times are in UTC, while the rule text refers to 11:59 PM ET. Because each contract has its own deadline, a reader should compare each price only with that contract's wording and close time.
Reading the snapshot
The provider observation time is 2026-10-14T09:00:06.225Z, and the source was retrieved at 2026-10-14T11:41:36.293Z [1]. These are the times for this saved record. They are not a live reading.
The saved Yes and No prices are:
- October 31, 2026 deadline: Yes 0.0095, No 0.9905
- November 30, 2026 deadline: Yes 0.065, No 0.935
- December 31, 2026 deadline: Yes 0.145, No 0.855
Within each contract, the two prices sum to 1.00. In this snapshot, the Yes price is higher for later deadlines. These prices are snapshots, not executable quotes or verified probabilities. They should not be averaged across deadlines, and the differences do not indicate an arbitrage opportunity.
All three saved markets for this event are included (3 of 3, with no partial sample). The sample warning states that these are all saved markets for the event but that this "does not establish that the providers list every possible real-world outcome" [1].
What remains uncertain
The excerpt ends mid-clause at "Unless the written instrument," and the supplied text does not contain the full resolution conditions [1]. The snapshot also does not include trading volume, liquidity, or number of traders, so it cannot show how much activity sits behind these prices. No other platform is included, so no cross-platform comparison is possible. Finally, the record contains no information about events after the observation time.

Overview
This PredictPedia contract asks whether the United States and Iran will have a qualifying written diplomatic instrument mutually signed or adopted by a specified date. The contract resolves to "Yes" if that happens by the deadline at 11:59 PM ET, and to "No" otherwise [1]. The provider's background describes a June 14, 2026 announcement: the two countries announced a written diplomatic agreement that includes a 60-day extendable period in which both committed to negotiate toward a "final deal" on Iran's nuclear program and other topics [1]. The saved provider event contains three date-specific markets, each asking whether a final deal will be reached by a different deadline: October 31, 2026, November 30, 2026, and December 31, 2026 [1]. Each market is a separate contract with its own end date, so the three cannot be read as one combined forecast. The listed end time for the December 31 market is 2027-01-01T04:59:00Z, which reflects the provider's time conversion of the 11:59 PM ET deadline rather than a separate event [1]. The price figures in this article are provider snapshots from the observation time shown in the dated status, not live or executable quotes. A price of 0.145 on the Yes side of the December market means the snapshot recorded that value. It does not establish a verified probability that a deal will occur [1]. The saved prices for the three Yes outcomes are 0.0095 for October 31, 0.065 for November 30, and 0.145 for December 31 [1]. These differences reflect the snapshot only, and they do not describe a trading opportunity. The contract rules in the saved excerpt are cut off partway through a sentence about the written instrument, so this article does not describe any exceptions or additional conditions beyond the core resolution rule [1].
Historical Context
The Iran nuclear deal is the common name for the Joint Comprehensive Plan of Action (JCPOA). It was an agreement to limit Iran's nuclear program in return for sanctions relief and other provisions, and it was finalized in Vienna on 14 July 2015 between Iran and the P5+1 together with the European Union [2]. On 8 May 2018, the United States under the first Trump administration announced its withdrawal from the JCPOA [3]. The June 14, 2026 written agreement described in the market background is a separate event from the 2015 JCPOA. The sources supplied here do not explain how the 2026 arrangement relates to the earlier agreement, so this article does not characterize that relationship [1][2][3].
Why It Matters
The contract measures whether a formal written instrument between the United States and Iran is mutually signed or adopted by a deadline. It does not measure whether negotiations are ongoing, whether talks are productive, or whether a final nuclear deal has been substantively agreed in content, beyond the written-instrument test stated in the rules [1]. The 60-day extendable negotiation period described in the background is relevant context for why the deadlines matter, but the provider's rules are what determine resolution [1]. For readers, the key distinction is between the announced written agreement, which the provider describes as having occurred on June 14, 2026 [1], and the future signing or adoption of a qualifying instrument that the contract asks about. The historical 2015 agreement and the 2018 withdrawal provide background on the long-running diplomatic relationship over Iran's nuclear program [2][3].
Snapshot context
The latest published provider snapshot for this topic was observed on 2026-10-14 at 09:00 UTC. It contains listings from Polymarket. Market descriptions and listed closing times define the contracts; they do not establish that the real-world outcome has occurred. This article does not include a separately verified news update. [1]
Frequently Asked Questions
What does this contract resolve to Yes?
It resolves to Yes if a qualifying written diplomatic instrument between the United States and Iran has been mutually signed or adopted by the specified date, 11:59 PM ET [1].
What happens if no qualifying instrument is signed by the deadline?
The contract resolves to No if no qualifying written diplomatic instrument has been mutually signed or adopted by the specified date [1].
Does a low Yes price mean a deal is unlikely?
A price is a snapshot from the provider and is not a verified probability. The saved Yes prices range from 0.0095 for the October 31, 2026 market to 0.145 for the December 31, 2026 market [1]. Readers should treat these figures as recorded values, not as forecasts.
Are the three markets the same question?
No. Each market asks the same underlying question with a different deadline: October 31, November 30, or December 31, 2026 [1]. Each has its own end date and price snapshot.
