Peace talks between Russia and Ukraine have made no progress, the Kremlin said, although trilateral negotiations involving the United States remain possible. U.S. President Donald Trump is scheduled to meet Ukrainian President Volodymyr Zelensky in New York on Tuesday during UN General Assembly week, as Washington continues efforts to mediate the conflict. Prediction markets now price a 20.5% chance of a ceasefire agreement by December 31, 2026, down from 22% over the previous 24 hours. No ceasefire has been achieved, and continuing battlefield activity and limited diplomatic progress are weighing on expectations. Observers will watch the Trump-Zelensky meeting, any further U.S.-Russia-Ukraine diplomatic contacts, military actions and statements from key officials for signs of changed market expectations.
