Analysis

This question asks whether the U.S. and China will formally announce a new AI safety agreement between mid-September 2026 and early 2027, with markets currently pricing a 22% chance this occurs by year-end. The low probability reflects both diplomatic constraints and the tight timeframe: bilateral AI safety agreements are rare and typically require months of negotiation, and no major announcement is currently anticipated before late 2026. The probability distribution across contract tiers suggests traders view a January 2027 deadline as only marginally more likely than December 2026, indicating skepticism about near-term progress. Key drivers include the current state of U.S.-China relations, ongoing AI policy discussions at international forums, and whether either government signals formal negotiation intent. The most immediate resolution trigger would be official statements from either government's foreign affairs or technology ministry announcing a new agreement.

  • No credible reporting as of mid-September 2026 indicates active negotiation or planned announcement of a new bilateral AI safety agreement between the U.S. and China
  • The 3¢ contract for October 1 resolution suggests traders assess <5% probability of announcement within 13 days, reflecting the compressed timeframe
  • Historical diplomatic precedent: bilateral AI agreements between major powers typically require 6+ months of formal negotiation and coordination across multiple ministries
  • The 22% probability for Jan 1, 2027 versus 17% for Dec 1 implies markets assign only ~5% incremental probability to agreements announced specifically in December
  • Resolution depends on official public announcement by either government or confirmation from credible news agencies—internal agreements or preliminary understandings would not satisfy contract terms

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.
