US-Iran nuclear deal?
Short Answer
The model sees potential mispricing for a US-Iran nuclear deal before 2028, assigning it 82.2% compared to the market's 67.0%. This suggests the market may overemphasize immediate hurdles, such as Iran's rejection of uranium stockpile removal and maximalist demands, which are cited as significantly reducing the likelihood of a deal in 2026.
1. Executive Verdict
- Trump's "managed containment" policy appears to preclude a comprehensive deal.
- Iran firmly rejects removing its highly enriched uranium stockpile.
- Nuclear enrichment and Strait of Hormuz status remain key sticking points.
- Pakistan is mediating indirect US-Iran negotiations, reportedly with slight progress.
- Longer-term market sentiment suggests more optimism for an eventual resolution.
- The Supreme Leader's directive forbids highly enriched uranium stockpile removal.
Who Wins and Why
| Outcome | Market | Model | Why |
|---|---|---|---|
| Before June | 6.0% | 51.8% | The Supreme Leader's directive forbidding HEU removal indicates an exceptionally low probability by mid-2026. |
| Before July | 21.0% | 51.8% | The Supreme Leader's directive forbidding HEU removal indicates an exceptionally low probability by mid-2026. |
| Before August | 29.0% | 51.8% | Persistent sticking points on nuclear enrichment and Hormuz significantly challenge the immediate deal outlook. |
| Before September | 31.0% | 51.8% | Continued indirect peace negotiations suggest the possibility of incremental progress despite major obstacles. |
| Before October | 64.0% | 53.0% | Research does not highlight strong supporting evidence. |
Current Context
The United States and Iran are engaged in indirect peace negotiations, mediated by Pakistan, as of May 22, 2026, seeking to end the war that began on February 28, 2026. While US Secretary of State Marco Rubio acknowledged "a little bit of movement," significant obstacles persist regarding Iran's uranium enrichment program and its proposal to establish a tolling system in the Strait of Hormuz [^][^][^][^]. These core issues continue to hinder progress despite the ongoing talks.
US demands for Iran's nuclear program remain firm, with President Trump insisting that Iran cease nuclear enrichment and surrender its stockpile of highly enriched uranium. He has warned that failure to agree to these terms could lead to a resumption of full-scale US military strikes [^][^][^]. Iran has largely rejected these demands as unacceptable, though some state media reports suggest a limited willingness to downblend existing uranium stockpiles [^][^][^][^]. This diplomatic context follows large-scale US and Israeli military strikes on Iranian nuclear infrastructure on June 13, 2025, and February 28, 2026, events that experts characterize as having ended traditional nuclear diplomacy, shifting the focus toward managed containment or repeated military preemption [^][^][^].
Prospects for a comprehensive US-Iran deal remain highly uncertain. Prediction markets and regional observers, such as UAE presidential advisor Anwar Gargash, view the likelihood of a comprehensive deal that resolves both the ongoing conflict and the status of the Strait of Hormuz as highly uncertain, often cited as a 50-50 scenario or lower [^][^].
2. Market Behavior & Price Dynamics
Historical Price (Probability)
Outcome probability
Date
This market has experienced a significant and consistent downward trend since its inception. Opening at a high of 18.0% on May 8, the price has since declined by over 70% to its current level of 4.8%. The most dramatic movement was a steep drop in the market's first week, falling from 18.0% to 6.7% by May 15. The price has continued to fall, establishing new lows and currently trading near the bottom of its historical 3.0% to 18.0% range.
The price action appears to be a direct reaction to reports from the ongoing, indirect peace negotiations. The market's initial optimism has given way to pessimism as news reports on May 22 highlighted "significant obstacles" to a deal, particularly regarding Iran's uranium enrichment program and a proposal for tolls in the Strait of Hormuz. While a US official acknowledged "slight progress," the emphasis on major disagreements likely fueled the continued sell-off to the current 4.8% low. Volume patterns suggest high conviction behind these moves; trading volume was strong at the market's peak on May 8 and surged again during the recent price drop on May 22, indicating that traders were actively selling on the negative news. The chart reflects a deeply bearish sentiment, with the initial high of 18.0% serving as a firm resistance level and traders consistently pushing the probability lower as diplomatic hurdles become more apparent.
3. Significant Price Movements
Notable price changes detected in the chart, along with research into what caused each movement.
Outcome: Before October
📈 May 22, 2026: 23.0pp spike
Price increased from 42.0% to 65.0%
What happened: There is no indication of specific social media activity serving as a primary driver for the 23.0 percentage point price spike on May 22, 2026. Traditional news reports on that date describe U.S.-Iran negotiations as largely stalled, citing major disagreements over Iran's uranium stockpile and control of the Strait of Hormuz, along with Supreme Leader Mojtaba Khamenei's 'red line' against transferring enriched uranium abroad [^][^][^]. Although Senator Marco Rubio noted "slight progress," he simultaneously rejected Iran's proposed tolling system for the Strait of Hormuz, creating a mixed and largely unfavorable context for a significant positive market surge [^]. Therefore, social media was not a primary driver, and the provided traditional news does not clearly explain the market's substantial upward movement.
📈 May 21, 2026: 10.0pp spike
Price increased from 32.0% to 42.0%
What happened: On May 21, 2026, news broke that Iranian Supreme Leader Mojtaba Khamenei reportedly issued a directive forbidding the removal of near-weapons-grade uranium from Iran, interpreted as a significant setback to US-led peace efforts [^][^][^][^]. This development would typically decrease, rather than increase, the probability of a "US-Iran nuclear deal?" outcome. While social media was active with Iranian propaganda videos aimed at influencing perception, no specific posts or viral narratives are identified as driving a spike in the likelihood of a nuclear deal [^]. Therefore, social media was largely irrelevant as a primary driver for the specified market's movement, and the research suggests the 10.0 percentage point spike likely refers to a different market altogether, 'Iran airspace closure' [^].
Outcome: Before July
📈 May 18, 2026: 11.0pp spike
Price increased from 16.0% to 27.0%
What happened: The provided web research does not clearly identify a primary driver for the 11.0 percentage point price spike in a "US-Iran nuclear deal?" occurring "Before July" on May 18, 2026. Information available around this time, such as reports from May 22, 2026, details that Supreme Leader Mojtaba Khamenei reportedly blocked the removal of Iran's uranium stockpile, which would likely decrease, not increase, the probability of a deal [^][^][^]. No specific social media activity from key figures or traditional news on May 18 indicating positive movement towards a deal was found in the given sources. Therefore, social media appears to be irrelevant in explaining this specific price movement based on the provided information.
📈 May 08, 2026: 10.0pp spike
Price increased from 27.0% to 37.0%
What happened: The 10.0 percentage point spike in the "US-Iran nuclear deal?" market on May 08, 2026, was primarily driven by a significant news announcement concerning negotiation progress. Reports in May 2026 indicated that Donald Trump announced a potential "15-point deal" where Iran would reportedly abandon nuclear weapons plans [^]. This announcement coincided with broader reports of "advancing US-Iran talks" around early May 2026 [^]. While no specific social media post from a key figure was identified as the direct trigger, this major development likely fueled widespread discussion and amplification across social media platforms. Social media was therefore a contributing accelerant rather than the primary driver.
4. Market Data

Market Discussion
Traders are divided on the US-Iran nuclear deal, with some betting on a quick agreement, citing Iran's potential motivation to finalize a deal before a possible Trump administration. Others are bearish, arguing that the US has less leverage, core nuclear and sanctions issues are too difficult to resolve quickly, and current diplomatic efforts like MOUs are insufficient for a comprehensive agreement. The discussion underscores the complex interplay of geopolitical pressures and internal motivations affecting the potential for a new deal.
5. What specific concessions regarding the Strait of Hormuz could break the current stalemate in US-Iran negotiations in 2026?
| Chance of deal by 2026 | 50-50 (Emirati official estimate) [^][^] |
|---|---|
| Iran's UNCLOS status | Signatory but not ratified, invokes "innocent passage" [^][^][^] |
| US position on Strait passage | International waterway requiring unimpeded "transit passage" [^][^][^][^][^][^][^][^][^] |
US-Iran negotiations face a deadlock over the Strait of Hormuz's status. The stalemate by 2026 centers on Iran's demand to formalize control over the Strait and potentially impose tolls, asserting its "sovereign role," a stance firmly rejected by the US [^][^][^][^][^][^][^][^][^]. The US maintains that the Strait is an international waterway necessitating unimpeded "transit passage" [^][^][^][^][^][^][^][^][^]. An Emirati official currently estimates only a "50-50" chance of a deal resolving this issue [^][^].
US concessions could involve economic relief and security assurances for Iran. To break the impasse, the US could offer several concessions in exchange for Iran's verifiable adherence to international navigation laws in the Strait. These include a phased lifting of specific economic sanctions impacting Iran's oil exports and access to international financial transactions, along with the release of a portion of Iran's frozen assets as a good-faith measure [^][^][^][^]. Furthermore, the US could commit not to use force against Iranian vessels or infrastructure in the Strait, provided Iran upholds international maritime law [^]. These economic assurances are crucial for Iran, which currently faces a US naval blockade on its ports [^][^][^][^][^].
Iran's adherence to international maritime law is key, alongside global views. On its part, Iran would explicitly affirm its adherence to the United Nations Convention on the Law of the Sea (UNCLOS) "transit passage" regime, which guarantees unimpeded passage through international straits, even during heightened security concerns [^][^][^][^][^]. While Iran is a signatory to UNCLOS, it has not ratified it and maintains that transit passage does not constitute customary international law, instead invoking "innocent passage" which allows for more coastal state control [^][^][^]. International reactions include China's opposition to militarization of the Strait [^], and Pakistan's suggestion of "joint control under UN auspices" [^].
6. What evidence supports the view that the Trump administration's policy of 'managed containment' precludes a comprehensive nuclear deal with Iran in 2026?
| Impact of "maximum pressure" | Extracts "temporary nuclear limits" but cannot dismantle Iran's broader security strategy without risking wider war [^] |
|---|---|
| Containment strategy focus | Disciplined, long term containment strategy oriented toward denial of capabilities and specific behaviors [^][^] |
| US 'maximum pressure' objectives | End Iran's nuclear threat, curtail ballistic missile program, stop support for terrorist groups [^] |
The Trump administration's "managed containment" policy is seen to preclude a comprehensive nuclear deal with Iran by 2026. This approach, characterized by "maximum pressure," may achieve "temporary nuclear limits" but is deemed unlikely to compel Iran to abandon its broader security strategy without significantly increasing the risk of a wider conflict [^]. Consequently, the strategy prioritizes denying specific capabilities and behaviors rather than negotiating a broad agreement that would require Iran to compromise national security objectives [^].
Containment focuses on managing risks, not country-wide transformation. The strategy is defined as a "disciplined, long-term" effort designed to manage Iran's capabilities and regional risks, rather than to "remake an entire country by force" or pursue an all-encompassing nuclear bargain [^]. The stated goals of "maximum pressure" align with this, aiming to end Iran's nuclear threat, curb its ballistic missile program, and halt support for "terrorist groups" [^]. Furthermore, Iran's own negotiating "red lines" regarding nuclear materials are consistent with an outcome of partial constraints instead of a comprehensive settlement [^]. While some market participants anticipate a U.S.-Iran nuclear deal around 2026, the argument against a comprehensive agreement rests on policy incentives and feasibility, not absolute impossibility [^].
7. How do the core demands of the Trump administration in the 2026 negotiations compare to the key terms of the 2015 JCPOA?
| Trump Admin 2026 Uranium Handover | 400kg highly enriched uranium to US [^][^][^][^] |
|---|---|
| Trump Admin 2026 Enrichment Moratorium | 20-year moratorium on all uranium enrichment [^][^][^][^] |
| 2015 JCPOA Enrichment Limit | 3.67% uranium enrichment [^][^][^] |
The core demands of the Trump administration in the 2026 negotiations are significantly more maximalist compared to the key terms of the 2015 JCPOA [^] [^] [^] [^] . The 2015 Joint Comprehensive Plan of Action (JCPOA) limited Iran to 3.67% uranium enrichment, capped centrifuge numbers, and converted the Fordow facility, in exchange for phased sanctions relief and access to frozen assets [^][^][^]. For the 2026 negotiations, the Trump administration's demands include the handover of 400kg of highly enriched uranium to the US, a 20-year moratorium on all uranium enrichment (a shift from earlier demands for a permanent ban), and limiting Iran to a single operational nuclear facility [^][^][^][^].
Beyond nuclear, 2026 demands include unrestricted Strait of Hormuz passage and other concessions. The Trump administration specifically demands no tolls or controls on the Strait of Hormuz [^][^][^][^]. Unlike the 2015 agreement, these 2026 negotiations are occurring in the context of an ongoing armed conflict that began in 2025 [^][^]. During these talks, the US is offering limited sanctions relief, such as restricted release of frozen assets, but is refusing war reparations. Conversely, Iran has demanded the lifting of all sanctions, war reparations, and regional sovereignty [^][^].
8. What level of economic or military pressure in 2026 might compel Iran to accept US demands regarding its enriched uranium stockpile?
| Stockpile Location Directive | Iran's near-weapons-grade enriched uranium stockpile must remain inside the country [^][^][^][^] |
|---|---|
| Efficacy of Current Pressure | Unprecedented military and economic pressure has not compelled Iran to accept US demands [^][^][^][^] |
| Negotiation Status | Deadlocked, with US threatening further military strikes [^][^][^][^] |
Iran remains unyielding to US demands regarding its enriched uranium stockpile. As of May 22, 2026, Iran has not been compelled by significant military and economic pressure, including US and Israeli air strikes, naval blockades, and sanctions, to accept US demands for the removal of its near-weapons-grade enriched uranium [^][^][^][^]. Supreme Leader Mojtaba Khamenei explicitly directed that the stockpile must stay within Iranian borders, directly challenging the core US objective [^][^][^][^].
US-Iran negotiations remain stalled over the uranium stockpile and related issues. The United States continues to threaten further military action if Iran does not comply [^][^][^][^]. Iran consistently refuses to transfer the stockpile abroad, citing security concerns, but some Iranian officials have proposed alternative solutions. These include diluting the uranium under international supervision to reduce its sensitivity while keeping it within Iranian territory [^][^][^][^].
Analysts perceive stockpile removal as a "red line" for the Iranian regime. This stance is attributed to Iran's fear of increased vulnerability to attacks, suggesting an unwillingness to cross this threshold regardless of external pressure [^][^][^]. The United States and its allies assert that the current level of pressure has not yet forced Iran to abandon its nuclear ambitions or its existing stockpile [^][^][^]. The available research does not indicate what specific additional economic or military pressure might compel Iran to accept the US demand to remove its enriched uranium stockpile.
9. What specific progress, if any, has been attributed to Pakistan's role as a mediator in the 2026 US-Iran talks?
| Temporary Ceasefire Brokered | April 8, 2026 [^][^][^][^] |
|---|---|
| Direct Talks Hosted | April 11–12, 2026 [^][^][^][^] |
| Current Mediation Status | Active with "slight progress" as of May 22, 2026 [^][^][^][^] |
Pakistan has made specific progress in mediating the US-Iran conflict. Pakistan successfully brokered an initial temporary ceasefire on April 8, 2026, marking a significant step in de-escalation [^][^][^][^]. Following this achievement, Pakistan hosted direct talks between the United States and Iran in Islamabad on April 11–12, 2026, which were a direct outcome of its mediation efforts [^][^][^][^].
Ongoing mediation efforts continue, though major obstacles persist. As of May 22, 2026, Pakistani Interior Minister Mohsin Naqvi is actively shuttling revised proposals between Washington and Tehran in an effort to sustain the fragile ceasefire and work towards a permanent peace agreement [^][^][^][^]. Reports indicate "slight progress" in these indirect negotiations [^][^][^][^]. However, the talks are hindered by unresolved disputes concerning Iran's nuclear enrichment levels and its stockpile of highly enriched uranium [^][^][^]. Additionally, the US has rejected Iran's proposed "tolling system" in the Strait of Hormuz [^][^][^]. It is important to note that a comprehensive nuclear deal remains a separate negotiation from the broader conflict-ending peace agreement [^][^][^].
10. What Could Change the Odds
Key Catalysts
As of May 22, 2026, the US and Iran are engaged in indirect negotiations, mediated by Pakistan, to end the war, with reports of "slight progress" [^] [^] [^] . However, major sticking points remain, including Iran's uranium enrichment, specifically the removal of HEU stockpiles, and control of the Strait of Hormuz [^][^][^]. Key diplomatic hurdles involve US demands for upfront nuclear concessions, such as the removal of HEU and dismantling enrichment facilities, while Iran seeks phased verification, sanctions relief, and its own terms for governing the Strait of Hormuz [^][^][^][^].
Prediction markets currently show extreme volatility and declining optimism for a near-term nuclear deal, with the probability for a deal by June 30, 2026, dropping significantly to approximately 28-30% following rejected proposals and reports of potential Iranian nuclear advancements [^] [^] [^] [^] [^] . Trading Odds & Predictions 2026 | Polymarket">[^][^][^][^][^]. In contrast, longer-term market sentiment through 2027-2029 remains more optimistic, at approximately 55-80%, reflecting an expectation that a diplomatic resolution will eventually be reached [^][^]. Key catalysts for a bullish outcome include the adoption of the one-page memorandum of understanding (MOU) currently under discussion [^][^][^]. Conversely, bearish triggers encompass military escalation, a failure to reach a consensus on HEU disposal, and hardline opposition within the Iranian government, such as from the IRGC [^][^][^].
