4-bullet brief | narrative

Polymarket puts only 10% odds on a Russia-Ukraine ceasefire being reached in 2026 under this multi-deadline contract.
Ukraine's 1,000-drone offensive and collapse of Trump's energy ceasefire are consistent with the low 10% market read; no ceasefire is the consensus price.
A companion Polymarket contract on Trump, Putin, and Zelensky appearing together before 2027 (CM-EVT-QP1YL1BSS0) sits at just 3%, reinforcing the dim prospects for near-term resolution.
Putin's reported proposal for a Trump-Xi summit without Zelensky (Story 23) adds a diplomatic wrinkle; markets are not pricing that format as a path to ceasefire.
