About This Event
In 2026 If the United States has agreed to, signed, or accepted a new Iran-US nuclear deal before X 1, 2026, then the market resolves to Yes. An agreement also made with other countries, i.e. multilaterally, is still encompassed if the United States participates. "A new Iran-US nuclear deal" means a formal written agreement signed by authorized representatives of both the United States and Iran that, 1, imposes verifiable restrictions on Iran's nuclear program, including limits on uranium enric
What Prediction Markets Are Forecasting
Prediction markets currently give this roughly a coin flip chance, at 54% probability. That means traders believe a new US-Iran nuclear deal before 2029 is slightly more likely than not, but the outcome is genuinely uncertain.
This isn't about a quick agreement in 2026. The market tracks whether any formal written deal gets signed before January 20, 2029. The deal would need verifiable limits on Iran's uranium enrichment, and the US would have to be a participant.
Why the Market Sees It This Way
The 2015 Joint Comprehensive Plan of Action (JCPOA) took years of negotiation. It limited Iran's enrichment in exchange for sanctions relief. Then in 2018, the Trump administration pulled out. Iran responded by enriching uranium well past JCPOA limits, and today it has enough enriched material for multiple bombs if it chose to build them.
Two things have shifted the odds recently. First, Iran's nuclear progress means time is running out for a diplomatic solution. Second, the 2024 US election creates a split scenario: a second Trump term likely means no deal, while a Democratic administration would probably restart negotiations. That political uncertainty is baked into the 54% number.
Iran also faces internal pressure. Its economy struggles under sanctions, and the regime may want relief. But hardliners in Tehran have shown little interest in returning to the old agreement's terms.
Key Dates and Events to Watch
The January 2029 deadline matters because it aligns with a presidential term. Watch for:
- Any resumption of indirect talks between US and Iranian officials
- IAEA inspections reports showing Iran's enrichment levels
- The 2024 US election outcome, which could dramatically shift probabilities
- UN Security Council resolutions or snapback sanctions expiring in October 2025
If Iran enriches to weapons-grade levels, that likely kills deal prospects. If it signals flexibility, odds could climb.
How Reliable Are These Predictions?
Prediction markets have mixed track records on international diplomacy. They correctly called the US withdrawal from the Paris climate agreement and the Iran nuclear deal pullout. But they underestimated how quickly Iran would restart enrichment after 2018.
The main limitation: these markets have relatively few traders compared to election markets. A 54% probability mostly reflects genuine uncertainty rather than strong conviction. Diplomatic negotiations also involve secret talks that markets can't anticipate, so sudden shifts are possible.
Current Market Outlook
Kalshi traders currently price a new US-Iran nuclear deal before January 2029 at 54%. That is essentially a coin flip. The market sees a deal as slightly more likely than not, but with massive uncertainty baked into the price. This is not a market pricing in a sure thing. It is a market saying the odds are basically even.
The specific question on Kalshi covers the full remaining term of the current presidential administration, through January 20, 2029. That is a long window. A 54% probability over nearly four years suggests traders expect serious negotiations but also serious obstacles.
Key Factors Driving the Odds
Iran has enriched uranium to 60% purity, just a technical step away from weapons-grade. The IAEA reported in November 2024 that Iran is the only non-nuclear-weapon state enriching at that level. That creates pressure on both sides to find a deal.
The 2015 JCPOA collapsed after the US withdrew in 2018. Iran then violated almost all its restrictions. A 2024 Congressional Research Service report noted that Iran now has enough enriched material for multiple bombs if it chose to weaponize. That is the backdrop.
The current US administration has signaled openness to diplomacy but has not prioritized Iran. The Biden team held indirect talks in 2021-2022 that nearly produced a deal, but it fell apart over Iran's demand for guarantees that a future US president could not withdraw again. That structural problem remains unsolved.
What Could Change These Odds
The big catalyst is the 2025 US presidential election. If a Republican wins who supports maximum pressure, the deal probability collapses. If the current administration stays, talks could restart. The market price reflects this binary political risk.
Iran's presidential election in June 2025 is another trigger. A moderate president could push for negotiations. A hardliner would likely block them.
The IAEA Board of Governors could refer Iran to the UN Security Council for non-compliance. That would kill deal chances for months. Conversely, a snapback of UN sanctions under the JCPOA's dispute mechanism would also crater the odds.
The 54% price makes sense as a midpoint between the diplomatic status quo and the political uncertainty of the next four years. The market is not predicting a deal. It is predicting that a deal remains possible but faces real headwinds from both Tehran's nuclear advances and Washington's political calendar.

Overview
The US-Iran nuclear deal, formally known as the Joint Comprehensive Plan of Action (JCPOA), is a multilateral agreement reached in July 2015 between Iran and the P5+1 countries (the United States, United Kingdom, France, Russia, China, and Germany), plus the European Union. The deal aimed to limit Iran's nuclear program in exchange for relief from economic sanctions. Under the JCPOA, Iran agreed to restrict its uranium enrichment to 3.67% purity, reduce its enriched uranium stockpile to 300 kilograms, and allow inspections by the International Atomic Energy Agency (IAEA). In return, sanctions on Iran's oil exports, banking, and other sectors were lifted. The agreement was seen as a major diplomatic achievement, but it faced opposition from Israel, Saudi Arabia, and many US Republicans who argued it did not address Iran's ballistic missile program or support for proxy groups. In May 2018, President Donald Trump unilaterally withdrew the United States from the JCPOA, calling it a 'horrible one-sided deal' and reimposed sanctions on Iran. Iran responded by gradually exceeding the deal's limits on enrichment, stockpile size, and centrifuge development. By 2020, Iran was enriching uranium to 60% purity, close to weapons-grade levels of 90%. The Biden administration, which took office in January 2021, expressed interest in rejoining the deal but negotiations in Vienna from April 2021 to August 2022 failed to restore the JCPOA. Key sticking points included the scope of sanctions relief, Iran's demand for guarantees that future US presidents would not withdraw again, and Iran's enrichment activities. As of 2025, the JCPOA is effectively defunct. Iran has enriched uranium to up to 60% purity and has an estimated stockpile of over 5,000 kilograms of enriched uranium, far exceeding the 300-kilogram limit. The IAEA has reported that Iran is the only non-nuclear-weapon state enriching uranium to 60% and that it has not provided credible answers about undeclared nuclear materials found at several sites. The US has maintained maximum pressure sanctions, while Iran has expanded its nuclear program and deepened ties with Russia and China. The possibility of a new deal in 2026 depends on political will in both countries, the outcome of US elections, and Iran's strategic calculus amid regional tensions. Interest in the topic remains high because a new deal could prevent Iran from developing a nuclear weapon, which would have major consequences for Middle East security, global oil markets, and nonproliferation efforts. Conversely, failure to reach a deal could lead to a nuclear-armed Iran, prompting a regional arms race and potential military conflict. The prediction market asks whether the US and Iran will agree to a new formal written agreement by 2026 that imposes verifiable restrictions on Iran's nuclear program, including limits on uranium enrichment.
Historical Context
The US-Iran nuclear dispute dates back to the 1950s, when the US provided Iran with its first nuclear reactor under the Atoms for Peace program. Iran's nuclear program expanded under the Shah, but after the 1979 Islamic Revolution, the US cut ties and Iran's nuclear activities became more secretive. In the 1990s, the US accused Iran of pursuing nuclear weapons, leading to sanctions. By 2002, an Iranian opposition group revealed undeclared nuclear facilities at Natanz and Arak, prompting IAEA investigations. Negotiations between Iran and the EU3 (UK, France, Germany) began in 2003 but stalled. In 2006, the UN Security Council imposed sanctions on Iran. The election of Hassan Rouhani in 2013, a moderate, opened the door for talks. The JCPOA was signed on July 14, 2015, after 20 months of negotiations. It was endorsed by UN Security Council Resolution 2231. The deal was implemented in January 2016, with Iran shipping out 98% of its enriched uranium and dismantling centrifuges. The deal unraveled after Trump's withdrawal in 2018. Iran began violating the deal in 2019, enriching to 4.5% and later 60%. By 2021, Iran's breakout time (the time needed to produce enough fissile material for one bomb) had shrunk from 12 months to a few weeks. The Biden administration's attempts to restore the deal failed, and by 2024, the JCPOA was considered dead. The IAEA board of governors passed resolutions criticizing Iran for non-cooperation, and Iran responded by expanding its nuclear program and barring some IAEA inspectors.
Why It Matters
A new US-Iran nuclear deal matters because it directly affects the risk of nuclear proliferation in the Middle East. If Iran obtains a nuclear weapon, it could trigger a regional arms race, with Saudi Arabia, Turkey, and Egypt potentially seeking their own bombs. This would destabilize the region and increase the chance of nuclear terrorism or accidental war. The deal also affects global oil markets: Iran has the world's fourth-largest oil reserves, and sanctions have removed about 1-2 million barrels per day from global supply. A deal could bring Iranian oil back, lowering prices and easing inflation. Conversely, no deal could lead to higher oil prices and supply disruptions. The deal also has implications for US relations with allies and adversaries. European allies want the JCPOA restored, while Israel and Gulf states oppose it. Russia and China have used the nuclear issue to expand their influence in Iran. Domestically, a deal could be a major political win for a US president, but it could also face opposition from Congress and pro-Israel groups. The outcome will shape US foreign policy for years and affect global nonproliferation norms.
