Russian President Vladimir Putin said Russia is making significant military advances in Ukraine and identified UK military installations as legitimate targets for Russian forces. He also warned that attacks on Russian soil would trigger military retaliation. The comments came as the Russia-Ukraine hostilities continue after the full-scale invasion began in February 2022. A prediction market now assigns a 24% YES probability to Russia entering Sloviansk by December 31, 2026, a price that reflects increased expectations of intensified Russian military activity. The remarks have raised concerns that the conflict could broaden beyond current battlegrounds, while future Russian statements, movements toward Sloviansk and other Ukrainian cities, and responses from UK and NATO officials could affect market pricing and perceptions of escalation.
