Analysis

Market participants estimate an 88% probability that the U.S. and China will announce a new mutual tariff agreement before January 1, 2027, with much lower odds (6%) for an agreement by September 1, 2026. The high overall probability reflects ongoing trade negotiations and political incentives for both governments to reach a deal, but the sharp decline in near-term probabilities suggests markets expect any agreement to take several months rather than materialize immediately. Key factors include the stated negotiating positions of both administrations, recent diplomatic communications, and historical patterns of U.S.-China trade negotiations. The timeframe matters significantly: traders are confident a deal will eventually emerge by year-end, but skeptical of imminent resolution within weeks.

  • Current status of active trade negotiations between U.S. and Chinese officials, including any scheduled talks or official statements about timeline expectations
  • Economic indicators and tariff impacts in both countries that might create urgency or reduce pressure to reach agreement quickly
  • Changes in U.S. or Chinese political leadership positions, policy shifts, or public statements that would signal willingness or unwillingness to compromise
  • Historical precedent: previous U.S.-China trade agreements and typical negotiation duration from serious talks to public announcement
  • Market pricing across the five time-based contracts shows declining probability with shorter deadlines, suggesting traders believe September and October resolution are unlikely but agreement by year-end is probable

How we compute these odds

SimpleFunctions aggregates live prediction-market contracts from Kalshi and Polymarket. Each slug groups contracts that resolve on the same underlying event, identified by venue event_id.

For binary slugs, the headline probability is the liquidity-weighted mid-price across all bound contracts. For multi-outcome slugs (e.g. elections with 3+ candidates), the headline is the leader’s price; we never arithmetically average disjoint outcomes — that would produce a number with no real-world meaning.

Snapshots refresh every 5 minutes during market hours; daily aggregates are computed at 04:00 UTC. The 30-day sparkline is drawn from per-ticker daily means stored in market_indicator_daily; 24h delta and movement events are derived from the same source.
