Russia's defence ministry confirmed at least seven people were killed in Moscow after Ukraine launched what officials described as the largest single attack of 2026. Russian authorities reported drone and missile impacts across the capital region overnight. Moscow simultaneously launched retaliatory strikes against Kyiv, igniting fires across multiple districts of the Ukrainian capital.
Neither side has released a full casualty count for the Kyiv strikes at this stage.
The scale of the exchange marks an escalation from the attritional pattern that defined the first half of 2026. A strike of this magnitude against Moscow, confirmed by Russian sources themselves, represents a shift in Ukrainian reach and willingness to absorb reciprocal risk.
Prediction markets tracking ceasefire probability and the duration of active hostilities move in opposite directions on news of this type: ceasefire contracts soften when either side demonstrates expanded strike capability, while markets on conflict continuation lengthen their implied timelines. An attack this size, confirmed by the defending party, is the kind of datapoint that reprices both.
