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

Platform comparison

Active sub-markets

Market context

The question hinges on whether Trump or his administration will formally announce a reduction, removal, or suspension of existing tariffs on China or Chinese goods by late May 2026. The resolution criteria are narrow: only definitive announcements tied explicitly to China qualify, excluding broader global tariff cuts or mere expressions of willingness to negotiate. The 0% implied probability reflects market scepticism that such a move occurs within the timeframe, despite Trump's history of tariff volatility and his stated openness to deal-making with Beijing.

Trump's first term saw escalating tariffs on Chinese imports, peaking at roughly 25% on many goods, yet he also paused increases and negotiated phase-one trade agreements. His 2024 campaign rhetoric emphasised tariff leverage as a negotiating tool rather than permanent policy. However, the Biden administration maintained most Trump-era tariffs, and reversing them requires explicit action—not passive continuation. Markets on Polymarket, Kalshi, and Betfair show divergent liquidity profiles on China-related trade outcomes; Kalshi's regulatory framework and KYC requirements may attract US-domiciled traders with stronger conviction on domestic policy timelines, whilst Polymarket's decimal-odds display suits traders comparing probability shifts across multiple China-trade scenarios simultaneously.

Key catalysts include scheduled US-China diplomatic meetings, quarterly earnings calls revealing tariff-impact guidance from major exporters, and any Trump statements during campaign or governance events. Reuters and Bloomberg regularly report on trade negotiation signals; traders should distinguish between Trump's public positioning (often maximalist) and actual policy announcements from Treasury or the Office of the US Trade Representative. The May 2026 window excludes mid-term election cycles but captures potential post-inauguration policy shifts if Trump returns to office.

Methodology

We read Trump-Xi Summit: What will Trump announce by May 22? from four platform perspectives: Polymarket (on-chain CLOB), Kalshi (CFTC-regulated exchange), Betfair Exchange (sports book exchange), Smarkets (peer-to-peer betting exchange). Polymarket's live quote comes directly from the Polygon order book; the other three are listed with their platform attributes — fees, KYC, settlement currency, payment options — because a 1:1 contract comparison without API access would be guesswork.

Resolution & payout

Settlement is the biggest difference between the four platforms: Polymarket on-chain in USDC (instant), Kalshi USD via CFTC (T+1), Betfair and Smarkets in local currency via bank withdrawal (T+1 to T+3). PolyGram routes every trade directly into Polymarket's on-chain settlement, which is why payouts land fastest.
