Resolution criteria on PolyGram: This market will resolve to "Yes" if there is a diplomatic meeting between the listed individual, acting as a representative of the United States, and representatives of Iran by May 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to “No”. To qualify, the listed individual must be physically present at the meeting and actively participate as a negotiator representing the United States. 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.
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
| J.D. Vance | 18% YES | 83% NO |
| Jared Kushner | 28% YES | 73% NO |
| Donald Trump | 3% YES | 97% NO |
| Marco Rubio | 5% YES | 96% NO |
| Steve Witkoff | 27% YES | 73% NO |
The question centres on whether J.D. Vance, currently Vice President-elect under Donald Trump, will conduct an in-person diplomatic meeting with Iranian representatives by the end of May 2026, acting in an official US capacity. The settlement criteria require physical presence and active participation as a negotiator. Polymarket's order book is currently pricing this scenario at 18% implied probability, reflecting substantial scepticism among traders that such a meeting will occur within the timeframe.
Historical precedent offers mixed signals. The Trump administration's first term (2017–2021) saw maximum pressure on Iran, including withdrawal from the JCPOA and targeted sanctions, with no high-level direct talks. However, the Biden administration pursued indirect negotiations through Oman and other intermediaries, though these did not materialise into formal meetings. Vance himself has expressed hawkish positions on Iran policy, which traders appear to be weighting as a headwind against diplomatic engagement. The 18% probability reflects a baseline expectation that Republican administrations favour containment over dialogue, though not zero chance of a strategic shift.
Key catalysts include any public statements from the Trump transition team on Iran policy (expected in early 2025), Iranian domestic political developments following their February 2024 elections, and unforeseen regional escalations that might force diplomatic channels open. The timeframe is tight: May 2026 allows roughly 16 months from Trump's inauguration. Traders should monitor announcements regarding special envoys, UN General Assembly meetings, or third-party mediation attempts, as these could signal movement towards direct engagement.
The meet-in-the-middle attack (MITM), a known-plaintext attack, is a generic space–time tradeoff cryptographic attack against encryption schemes that rely on performing multiple encryption operations in sequence. The MITM attack is the primary reason why Double DES is not used and why a Triple DES key (168-bit) can be brute-forced by an attacker with 256 spa

Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome, a two-hour dispute window opens, and if no one stakes a counter-claim the payout is final. Contested outcomes escalate to UMA token-holder voting. Payouts clear in USDC to the winning side.
The mechanics for trading "Who will meet with Iran by May 31?" are the same as any other PolyGram event contract. Each YES share resolves to $1 if the event happens, or $0 if it doesn't. The current price between 0¢ and 100¢ is the market's probability estimate, set live by the order book.
$74K in lifetime turnover and $74K of resting liquidity puts this market in the above the median by volume for vance contracts on PolyGram. Order-book depth is exceptional — among the deepest order books in the category.
Last 24 hours alone saw $3K in turnover, consistent with the market's lifetime daily-average pace.
The market has been open for under a month — fresh enough that information asymmetry remains a real factor.
Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.
Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome, a 2-hour dispute window opens, and if uncontested the payout is final. Contested outcomes escalate to UMA token holders.
This prediction market is scheduled to close on 31 May 2026. After the resolving event occurs, settlement typically clears within 24 hours once the UMA optimistic oracle confirms the outcome. All payouts are in USDC on the Polygon network.
