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

Platform comparison

Market context

The market currently prices at 0% the likelihood that Trump announces a tariff reduction on Chinese goods or goods from China by late May 2026. This reflects trader conviction that no such announcement will materialise during the specified window, with conditional YES tokens trading at near-zero USDC value on Polygon.

Trump's first term (2017–2021) established the template for reading this contract. He imposed successive tranches of tariffs on Chinese imports, reaching roughly $370 billion in annual trade volume under duty by 2020, yet announced reductions sparingly and only under specific conditions—primarily the Phase One trade deal signed in January 2020, which involved Chinese agricultural purchases rather than tariff elimination. His rhetoric consistently favoured tariff maintenance as leverage. The 0% probability reflects historical precedent: Trump treated tariffs as negotiating tools rather than concessions to announce casually, and reversals required formal agreements with measurable Chinese commitments.

Traders monitoring this contract should track scheduled bilateral meetings, trade negotiation timelines, and any formal announcements from the Office of the US Trade Representative. The Biden administration maintained Trump-era tariffs largely intact through 2024, establishing continuity that shapes baseline expectations. Any Trump administration statement must explicitly reference tariff reduction, removal, or suspension tied to China specifically—vague expressions of openness to talks or general tariff reviews will not settle the contract to YES. Announcements tied to broader multilateral tariff policy or unrelated to China-specific trade dynamics fall outside resolution criteria.

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.

FAQ

Is this market available outside the US?

PolyGram is available in most jurisdictions where Polymarket isn't directly accessible. Polymarket itself is geo-blocked in the US/UK/EU. Always check local regulations.

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.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
