The Kyiv International Institute of Sociology (KIIS) surveyed 1,031 Ukrainians aged 18 and older by computer-assisted telephone interviews using a random sample of cell phone numbers across regions of Ukraine under government control. Between Oct. 8 and 9, 43% of respondents trusted Zelensky and 52% did not. Between Oct. 10 and 16, after Trump's pressure campaign had begun, trust rose to 57% while distrust fell to 39%.
Across the full survey period, from Oct. 8 to 16, 54% said they trusted the president, including 22% who trusted him completely and 32% who trusted him somewhat. At the same time, 41% said they did not trust him, with 24% distrusting him completely and 17% somewhat.
The findings come as relations between Kyiv and Washington deteriorate. Ukraine accuses the U.S. of using military assistance and access to technology to press it to halt strikes on Russian oil refineries, according to the report. Trump has repeatedly criticized Zelensky, saying Ukraine should consider finding someone else to negotiate on its behalf. According to the report, Trump has shifted toward Moscow in what appears to be an effort to lower domestic fuel prices. On Oct. 9, he announced a plan to purchase Russian diesel despite years of U.S. sanctions on Russian energy products, and ordered Ukraine to stop attacking Russian oil refineries.
KIIS Executive Director Anton Hrushetskyi said many Ukrainians criticize Zelensky over domestic problems such as corruption in his team and poor personnel decisions, but are quieter when it comes to foreign relations and defense support. "There are indeed many Ukrainians who criticize President Zelensky for the various problems facing Ukraine and Ukrainians," he said. "While Ukrainians may be genuinely outraged by instances of corruption among members of the president's team or by poor personnel decisions, the voices of critics are significantly quieter when it comes to relations with other countries, securing support for the country in the defense sector, and, in general, defending Ukraine's interests on the international stage."
Before Trump's criticism, Zelensky's rating had been tested by major corruption scandals. The overall figures matched those recorded in late August and early September, suggesting confidence in Zelensky had remained largely unchanged over the past month. A similar rally occurred in 2025, when Zelensky's approval rating rose to 68% after his heated exchange with Trump in the Oval Office, after a February 2025 survey found 57% trusted the president.
