China x Japan military clash before 2027?
What the market is pricing
The market is pricing this scenario at single-digit, unlikely odds, reflecting a low perceived probability of armed conflict over the roughly 13-month window. The market has moved down 1 point over the past week, suggesting modest declining confidence in the scenario, though pricing remains stable day-to-day. Current odds place this outcome as a long shot among tracked geopolitical risks.
How this market resolves

It resolves No if no such encounter occurs by the deadline.

What could move it
- Any official report or independent confirmation of a military engagement meeting the 'use of force' definition would settle it directly; absence of such an incident through the end of 2026 would close it as No.
- Escalations in existing tensions (statements, naval incidents, military drills) could shift odds before resolution, but only an actual use-of-force encounter triggers a Yes outcome.
- The roughly 13 months remaining until the December 31, 2026 deadline leave time for market repricing if geopolitical conditions shift materially.
