Strong advance participation in Yes-leaning Reykjavík partly offsets a last-minute Gallup swing toward No, so referendum passage is narrowly favored.
Late surveys disagree: Maskína retained a slight Yes edge, while the newer Gallup reading put No marginally ahead. Heavy advance voting in Yes-leaning Reykjavík and the ballot’s limited commitment to restarting talks provide Yes a narrow advantage, but recent movement toward No leaves either outcome readily plausible.
Points to YES
- A late Maskína survey put Yes slightly ahead, preserving a narrow path to passage if its respondents better reflect actual turnout.In fieldwork conducted August 21–25, 2026, Maskína found a slight Yes edge among decided respondents.
- The ballot authorizes negotiations rather than membership, giving cautious voters a lower-commitment reason to support Yes.A report published August 26, 2026, noted that any eventual EU membership agreement would face a separate referendum.
- Heavy advance participation in Reykjavík locks in more ballots from the strongest Yes region, modestly improving the passage path.By August 26, 2026, Reykjavík-region advance voting was running above the reported nationwide share.
Points to NO
- The newest Gallup survey put No marginally ahead, indicating that late movement may have erased the earlier Yes advantage.Gallup fieldwork conducted August 24–27, 2026, found a narrow No lead that was not statistically significant.
- Opposition outside Reykjavík creates a broad geographic obstacle that could overwhelm the capital’s stronger support for restarting talks.Maskína’s July 22–29, 2026, survey found majority opposition outside the capital, including especially strong opposition in East Iceland.
