4-bullet brief | narrative

The Polymarket contract on a Ukraine-Russia ceasefire in 2026 prices at 15%, keeping the outcome a long shot.
Overnight Russian strikes involving 130 drones and ballistic missiles are consistent with the market's low ceasefire probability; intensive bombardment runs directly counter to de-escalation.
The companion Polymarket contract on a full peace deal before 2027 (CM-EVT-DCQYWYX424) prices at only 11%, with territory cession by Ukraine (CM-EVT-XP7FFT2MC9) at 7%, showing a consistent low-probability cluster across peace outcomes.
Resolution on the ceasefire contract uses Polymarket's UMA oracle; a formal, verified cessation of hostilities is required, not an informal pause or local truce.
