Two late polls split narrowly after earlier Yes leads, so the referendum to restart EU negotiations is favored but far from guaranteed.

Yes remains more likely because one late survey retained a narrow lead and the ballot asks only to reopen negotiations, while high living costs strengthen the case for exploring EU terms. However, the final Gallup survey moved narrowly toward No, and concerns over fishing rights and sovereignty leave substantial room for rejection.

Points to YES

Maskína’s final survey kept Yes narrowly ahead, making a slim passage the most plausible outcome despite weakening support.
A survey fielded on August 21–25 found 51.3% of decided respondents intended to vote Yes, down from earlier readings.
The ballot’s limited scope lowers the commitment required from cautious voters, supporting Yes among people willing to explore terms without endorsing membership.
On June 20–22, the government emphasized that the referendum concerned only resuming negotiations and would not decide EU membership.
High prices and borrowing costs strengthen the appeal of reopening talks by giving voters an economic reason to examine closer EU integration.
On August 29, Iceland’s policy rate was reported at 8% versus 2.25% in the euro area, while Yes campaigners argued that integration could ease borrowing costs.

Points to NO

Gallup’s final survey put No narrowly ahead, showing enough late movement to overturn a small Yes advantage.
Gallup fieldwork conducted on August 24–27 found 51.6% of decided respondents opposed restarting negotiations and 48.4% supported it, with the difference not statistically significant.
Fishing-sovereignty concerns give No a powerful closing argument because a major export sector could become subject to contested EU rules.
A report published August 26 said fishing and marine industries generated almost 40% of Iceland’s exports and made control of fishing grounds central to the No campaign.
