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

Active sub-markets

Market context

The contract prices a Trump administration announcement of tariff relief on Chinese goods or goods from China between now and 22 May 2026 at zero probability on Polygon. This reflects the market's assessment that such an announcement remains extraordinarily unlikely within the settlement window, despite the geopolitical fluidity surrounding US-China trade relations. The resolution criteria require a definitive, public announcement specifically tied to China or Chinese goods—not merely expressions of willingness to negotiate or global tariff adjustments that happen to include China.

Trump's first term established a pattern of sustained tariff escalation against China rather than rollback, with the Section 301 tariffs imposed in 2018 remaining largely intact through his presidency and into the Biden administration. The few instances where Trump announced tariff suspensions or reductions were typically linked to bilateral trade deal progress (notably the Phase One agreement in January 2020) or specific sectoral negotiations. Current market pricing suggests traders view the absence of comparable deal momentum as the primary reason for the 0% probability, particularly given the 16-month timeframe offers limited runway for the negotiation-to-announcement cycle that historically preceded any Chinese tariff relief.

Traders monitoring this contract should track formal trade negotiations, any Trump administration statements on China policy, and scheduled high-level diplomatic engagements. The market will likely remain at or near zero unless concrete evidence emerges of active deal-making between Washington and Beijing, with particular attention to whether Trump pursues a new trade agreement framework or signals willingness to unwind existing tariff regimes as part of broader negotiations.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

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.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.
