Resolution criteria on PolyGram: This market will resolve to "Yes" if there is a diplomatic meeting between representatives of the United States and Iran by the listed date, 11:59 PM ET. Otherwise, this market will resolve to “No”. A diplomatic meeting refers to a deliberate meeting between representatives of the listed countries who are acting in an official capacity and are authorized to engage in negotiation or diplomacy regarding US-Iranian relations on behalf of their governments. Meetings conducted indirectly, for example, through designated mediators, facilitators, or interlocutors acting with the knowledge and authorization of the relevant governments, will qualify.
PolyGram is an on-chain prediction market where you trade YES or NO outcome shares with real USDC on Polygon. For this market, buy YES if you believe the event will happen, or NO if you think it won't. Your maximum loss is your stake — winning shares pay $1.00 each at resolution. Unlike sportsbooks, there is no house edge: prices are set by supply and demand from other traders and reflect the crowd's real-time probability.

The market concerns whether official representatives of the United States and Iran will hold a direct diplomatic meeting by 30 April 2026. Such a meeting would require both governments to authorise their representatives to negotiate or discuss bilateral relations face-to-face, excluding indirect talks through intermediaries or facilitators. The current order book on Polymarket implies zero probability of this occurring within the settlement window, reflecting prevailing market sentiment about near-term US-Iranian diplomatic engagement.
Historical precedent suggests direct US-Iran talks remain rare but not unprecedented. The 2015 Joint Comprehensive Plan of Action (JCPOA) negotiations involved sustained diplomatic contact, whilst the 2016 prisoner exchange demonstrated capacity for bilateral coordination. However, the Trump administration's 2018 withdrawal from the JCOPA and subsequent maximum pressure campaign reversed this trajectory. Under the Biden administration, indirect talks through Oman occurred in 2021-2022, yet no direct ministerial or official meetings materialised despite nuclear negotiations continuing through intermediaries.
Traders should monitor several catalysts through April 2026. Changes in US administration following the 2024 election will substantially alter diplomatic posture; a Harris or Democratic administration might pursue backchannel talks, whilst a Republican one would likely maintain distance. Iranian domestic politics, particularly factional shifts following presidential elections in 2025, could affect Tehran's willingness to engage. Regional developments—particularly escalation in Gaza, Lebanon, or direct Israeli-Iranian confrontation—would either necessitate or preclude diplomatic contact. Any announcement of talks would likely emerge through official state department or Iranian foreign ministry statements rather than surprise meetings.
Since 28 February 2026, the United States and Israel have been engaged in a war with Iran and its regional allies. The conflict began when the US and Israel launched airstrikes on Iran, targeting military and government sites and assassinating several Iranian officials, including Supreme Leader Ali Khamenei. The surprise attacks were launched during negotiat
On April 12, 2025, Iran and the United States began a series of negotiations aimed at reaching a nuclear peace agreement, following a letter from US president Donald Trump to Iranian supreme leader Ali Khamenei. Trump set a 60-day deadline for Iran to reach an agreement. After the deadline passed without an agreement, Israel launched numerous strikes against
Relations between Iran and the United States in the modern-day are unsettled and have a troubled history. They began in the mid-to-late 19th century, when Iran was known to the Western world as Qajar Persia. Persia was very wary of British and Russian colonial interests during the Great Game. By contrast, the United States was seen as a more trustworthy fore
The Red Sea crisis is an ongoing armed conflict and maritime crisis instigated by the Houthis, an armed group in Yemen. The Houthis began launching missiles and armed drones at Israel in response to the Gaza war, and have seized or attacked dozens of merchant and naval vessels travelling through the Red Sea which they claimed are linked to Israel. These acti
