Resolution criteria on PolyGram: If Marco Rubio visits China by the specified date, 11:59 PM ET, this market will resolve to "Yes". Otherwise, this market will resolve to "No". For the purpose of this market, a "visit" is defined as Rubio physically entering the terrestrial or maritime territory of China. Whether or not Rubio enters Chinese airspace during the timeframe of this market will have no bearing on this market's resolution. The primary resolution source for this information will be official information from Marco Rubio, the US Federal Government, and the Chinese government; however, a consensus of credible reporting will also be used.
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
| April 30 | 0% YES | 100% NO |
| December 31 | 96% YES | 5% NO |
| June 30 | 89% YES | 12% NO |
Marco Rubio, confirmed as US Secretary of State in February 2025, visiting mainland China before the end of 2026 remains an uncertain prospect. The current 0% implied probability on Polymarket's order book reflects the absence of any announced plans or diplomatic schedule suggesting such a visit within the settlement window. The market's formation at this extreme reflects genuine uncertainty about whether Rubio—known for his hawkish stance on China policy—would undertake an official visit to Beijing during the Trump administration's second term.
Historical precedent suggests US Secretaries of State typically visit China within their tenure, though timing varies considerably. John Kerry visited in 2016 during Obama's final year; Mike Pompeo's China visit in 2018 followed months of escalating trade tensions. Rubio's appointment signals a more confrontational approach to US-China relations than his predecessors, which could either necessitate high-level engagement to manage tensions or delay diplomatic visits indefinitely. The 0% probability reflects trader scepticism that such engagement would occur within this specific timeframe.
Traders should monitor several catalysts: official State Department travel schedules, statements from the Chinese Foreign Ministry regarding bilateral engagement, and developments in US-China relations that might necessitate top-level diplomatic contact. Any announcement of a scheduled visit would likely move the market sharply. The settlement window extends through December 2026, providing nearly two years for circumstances to shift, though current market pricing suggests traders assess this outcome as highly unlikely given present diplomatic postures.
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.
