## Analysis

Market participants estimate a 46% probability that Russia and Ukraine reach a ceasefire agreement by December 31, 2026. The near-term contract (June 30) trades at 9%, suggesting traders view a truce within the next weeks as unlikely. The December deadline implies that any agreement would require either major battlefield developments shifting negotiating positions, a change in political leadership in one or both countries, or diplomatic intervention reshaping incentives. The core driver of uncertainty is whether military dynamics—territorial control, casualty rates, weapons availability—will produce stalemate conditions that make negotiation attractive to both sides. Key upcoming variables include ammunition production capacity, NATO posture shifts, internal political movements, and whether either side achieves decisive territorial gains over the next six months.

### Key factors

- Current territorial front lines and their stability or movement over the next 90 days will indicate whether either side perceives military advantage or stalemate
- U.S., EU, and other major power diplomatic signaling—statements on negotiations, sanctions policy, or weapons supply—directly influences both sides' perceived costs of continued conflict
- Ukrainian domestic political viability of any ceasefire terms versus Russian demands will constrain what agreements are acceptable to Kyiv
- Russian military losses, recruitment capacity, and domestic political pressure will determine Moscow's willingness to negotiate from current positions
- Any scheduled major diplomatic summit, peace proposal rollout, or leadership transition announcement before year-end would shift market expectations materially

## Methodology

Headline is the **leader's price**, not an arithmetic mean — averaging disjoint winner-take-all outcomes is meaningless. Per-outcome prices come from the venue's last-traded mid; cross-venue values are simple means across contracts on each venue.
