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

Market context

The Trump administration's approach to China tariffs has shifted considerably since the first term. During 2017–2020, Trump imposed successive tranches of duties on Chinese goods, culminating in tariffs affecting roughly $370 billion in annual imports. His second term began with threats of further increases, including proposed 25% baseline tariffs on all Chinese goods. A summit between Trump and Xi Jinping, should one occur before May 2026, would represent a potential inflection point where tariff policy could be announced. The market requires a definitive announcement specifically tied to China or Chinese goods—not a broader tariff reduction affecting multiple nations simultaneously.

Historical precedent suggests caution about reading summit announcements as tariff reversals. Trump's 2019 "Phase One" trade deal with China involved modest tariff reductions on select goods but left the bulk of duties intact. The subsequent Biden administration maintained nearly all Trump-era tariffs despite campaign rhetoric about reassessing them. Current market pricing at 0% reflects scepticism that Trump would announce reductions rather than escalations. Traders monitoring this outcome should track official statements from the Office of the US Trade Representative and presidential remarks specifically naming China or Chinese tariffs, distinguishing these from general trade policy announcements or negotiation signals.

Key catalysts include scheduled bilateral meetings, quarterly trade data releases that might influence negotiating positions, and domestic political pressures around inflation or business lobbying. Reuters and official White House statements remain the authoritative sources for settlement-qualifying announcements. Programmatically, traders would flag keywords ("China tariff reduction," "suspension," "removal") in official communications and cross-reference dates against the May 2026 deadline, filtering out conditional language or expressions of intent that fall short of definitive policy announcements.

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.
