Russia has intensified its military campaign against Ukraine with air strikes on Kyiv for a sixth consecutive night, prompting European officials to seek additional air-defense systems. The escalation follows recent ballistic-missile attacks on the capital that caused casualties and has increased concern about possible further Russian territorial advances. Prediction markets are pricing a higher likelihood of Russian forces entering Ukrainian cities such as Sloviansk by Dec. 31, 2026, though the source provides no specific probability. Future market expectations may be influenced by reported Russian military movements, satellite imagery, changes in Western military support, ceasefire negotiations and international sanctions. The developments carry broader implications for European security.
