Trade: How long will Trump and Xi shake hands when they meet?
Resolution criteria on PolyGram: This market will resolve according to the length of the longest filmed handshake between Donald Trump and Xi Jinping during the day of their next meeting in 2026 (in the local timezone of the location of their next meeting). Any handshake recorded on that date will qualify. If no handshake occurs during the date of their next meeting, or if no meeting takes place by December 31, 2026, 11:59 PM ET, this market will resolve to “No Handshake”. If a handshake is photographed but not captured on video, this market will resolve to "Photographed only". Duration will be measured from the exact moment their hands make initial physical contact until the exact moment either breaks contact.
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 context
The market hinges on whether Donald Trump and Xi Jinping will meet in person during 2026 and, if so, whether their handshake will exceed a specified duration when filmed. The current order book on Polymarket reflects a 1% implied probability, suggesting traders assess a meeting as unlikely, a handshake as improbable if they do meet, or both conditions as jointly improbable within the settlement window.
Historical precedent offers limited guidance on handshake duration as a measurable metric. Trump and Xi last met in person at the G20 summit in Buenos Aires in November 2018, where their handshake was captured on camera but no standardised duration measurement exists in public records. Trump's documented handshakes with other world leaders have ranged from perfunctory to prolonged, often reflecting diplomatic messaging; his 2017 handshake with French President Macron lasted approximately 25 seconds and drew commentary on competitive grip dynamics. Xi typically maintains more formal, measured greeting protocols in diplomatic settings. The 1% probability reflects scepticism about both the likelihood of a bilateral meeting materialising and the prospect of extended physical contact being recorded if one does occur.
Traders should monitor US-China diplomatic calendars and summit schedules announced by both governments. Recent tensions over Taiwan, trade policy, and technology restrictions have constrained high-level in-person engagement. Any announcement of a planned bilateral meeting, multilateral summit attendance, or state visit would materially shift the probability. The settlement window extends through December 2026, allowing time for diplomatic thaw or escalation to alter meeting prospects.

How active is this market?
$106K in lifetime turnover and $128K of resting liquidity puts this market in the around the median by volume for politics contracts on PolyGram. Order-book depth is exceptional — among the deepest order books in the category.
Last 24 hours alone saw $16K in turnover, well above the lifetime daily-average for this market — a clear sign of news catalysing trader activity right now.
The market has been open for 3 months — the price has had time to stabilise as new information arrived.
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.
Key terms
- YES / NO share
- A binary outcome token that pays $1.00 if the underlying claim resolves true (YES) or false (NO), and $0 otherwise. The market price between 0¢ and 100¢ is the implied probability.
- CLOB
- Central limit order book. The matching engine that pairs YES buyers with NO buyers (effectively the same trade). Polymarket's CLOB on Polygon executes trades on-chain via the conditional-tokens framework.
- Liquidity
- USDC capital sitting in resting limit orders inside the order book. Deeper liquidity means smaller slippage on large trades and a tighter bid-ask spread.
- UMA optimistic oracle
- The on-chain dispute system that settles each Polymarket market. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution.
- Slippage
- The difference between the displayed mid-price and your fill price. Affects market orders most; limit orders avoid slippage but may take time to fill.
- Conditional token
- ERC-1155 outcome share issued by Gnosis Conditional Tokens on Polygon. The token type that resolves to $1.00 or $0.00 at settlement.

Risk and regulatory note
Prediction-market positions can lose 100% of staked capital. Outcomes are uncertain by definition — historical accuracy of crowd-implied probabilities is high in aggregate but not for any single market. PolyGram does not provide investment advice. Trade only with capital you can afford to lose.
Regulatory status varies by jurisdiction. Germany, the United States, and most EU countries treat Polymarket-style event contracts under one of three frameworks: financial derivative, gambling product, or unregulated novel asset. Consult local counsel before trading.
