Resolution criteria on PolyGram: This market will resolve to "Yes" if Donald Trump meets with Mojtaba Khamenei between market creation and the listed date, 11:59 PM ET. Otherwise, this market will resolve to "No". A meeting is defined as any encounter where both specified individuals are present and interact with each other in person. An exchange of words, handshake, direct conversation, or other clear personal interaction between the named individuals will qualify as a meeting. Merely standing in proximity, making eye contact, or being present in the same room or event without direct interaction will not qualify. The resolution source will be a consensus of credible reporting.
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.
Market outcomes
| June 30 | 1% YES | 99% NO |

A direct, in-person meeting between Donald Trump and Ayatollah Mojtaba Khamenei—the Supreme Leader's son and a significant figure within Iran's power structure—remains extraordinarily unlikely given the current geopolitical landscape. Such an encounter would represent a dramatic diplomatic shift, requiring both parties to overcome decades of institutional hostility and navigate complex domestic political constraints on both sides.
Historical precedent offers limited guidance. No sitting or former US president has met directly with Iran's Supreme Leader since the 1979 revolution, and meetings with senior family members are equally rare. The 1971 Nixon-Kissinger opening to China involved months of secret diplomacy through intermediaries before any public engagement. Iran's leadership has consistently rejected direct talks with Trump specifically, citing his 2018 withdrawal from the JCPOA and subsequent sanctions regime. The current 1% implied probability on Polymarket's order book reflects this structural impasse—traders are pricing in near-zero likelihood of the diplomatic machinery shifting sufficiently by end-2026.
Catalysts that could move this market are narrow but identifiable. A major regional conflict resolution, significant sanctions relief negotiations, or unexpected domestic political changes in either country could theoretically create space for backchannel discussions. Recent reporting from Reuters and AP News indicates Iran's government remains focused on regional proxy activities rather than direct engagement with the Trump administration. Any credible reporting of preliminary diplomatic contact or announced summit would likely trigger immediate repricing, though current order book depth suggests traders view such scenarios as highly improbable within the settlement window.
Relations between North Korea and the United States have been historically tense and hostile. The two countries have no formal diplomatic relations. Instead, they have adopted an indirect diplomatic arrangement using neutral intermediaries. The Swedish Embassy in Pyongyang is the U.S. protecting power and provides limited consular services to U.S. citizens.
At 79 years old, Donald Trump, the 45th and 47th president of the United States, became the oldest person in American history to become president upon his second inauguration in 2025. In July 2024, five weeks after his 78th birthday, he became the oldest presidential nominee of a major party. Should he serve as president until at least August 15, 2028, he wo
Donald Trump's use of social media attracted worldwide attention since he joined Twitter in March 2009. Over nearly twelve years, Trump tweeted around 57,000 times, including about 8,000 times during the 2016 election campaign and over 25,000 times during his first presidency. The White House said the tweets should be considered official statements. When Twi
The trumpet is a brass instrument. The most common type of trumpet is a transposing instrument in B♭, with pitches sounding a whole step lower than written. The trumpet family includes instruments ranging from the piccolo trumpet, with the highest register in the brass family, to the bass trumpet, pitched one octave below the standard B♭ or C trumpet.
