Ukrinform reports that Putin claimed at the Valdai Club on October1 that Russia gained 1,301 square kilometres of Ukrainian territory in September2026. The article attributes to ISW a September net Russian territorial loss of 80.81 square kilometres, or 175.18 when including advances without full control. These are distinct attributed measures, not independently established territorial facts.

The linked Ukrinform report was read; the primary Putin statement and ISW analysis were not. Reported gross gains and estimated net losses are different measures and remain attributed.
