Trump-Xi Summit: What will Trump announce by May 22?

Market context

The Trump administration's approach to China tariffs remains the central variable for this market. Since returning to office in January 2025, Trump has maintained existing tariff schedules whilst signalling willingness to negotiate. A formal summit announcement or bilateral trade agreement could trigger tariff relief, though the administration has historically used tariff threats as negotiating leverage rather than quickly reversing them. The market's 0% probability reflects scepticism that any tariff reduction will be formally announced by May 2026, a roughly sixteen-month window.

Historical precedent suggests caution. During Trump's first term (2017–2021), despite multiple summits and negotiations with Xi Jinping, announced tariff reductions on Chinese goods remained limited. The Phase One trade deal of January 2020 involved Chinese commitments to purchase American goods rather than US tariff relief. Subsequent administrations maintained most Trump-era tariffs, establishing them as durable policy. The current market pricing implies traders assess the probability of a reversal as negligible, consistent with the structural entrenchment of US–China trade restrictions across both parties.

Traders should monitor official White House statements, USTR announcements, and any scheduled Trump–Xi engagement. Recent reporting from Reuters and Bloomberg has tracked ongoing trade tensions rather than negotiation signals. The settlement criteria demand explicit, definitive announcements tied specifically to China or Chinese goods—expressions of openness or preliminary discussions do not qualify. Regulatory accessibility for UK traders involves CFTC reach over Polymarket's US operations; the £1,000 equivalent no-KYC threshold applies to individual positions, whilst German GlüStV requirements may affect EU-based participants' participation in this market.

Methodology

We track Trump-Xi Summit: What will Trump announce by May 22? on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
