The Social Democrats are projected to finish as the largest party in Dáil Éireann following the June 2026 General Election, according to RTÉ's election-night projection — a result that would mark the most significant breakthrough in the party's history.
As counting got under way this evening across all ten constituencies, RTÉ's model points to the Social Democrats taking the lead ahead of Fine Gael, with Sinn Féin and Fianna Fáil trailing in a sharply realigned political landscape. Polls closed at 20:04 IST, and the first boxes are now being opened.
If the projection holds, the Social Democrats would once again top the poll nationally, consolidating their position as the dominant force in Irish politics and the single largest grouping in the new Dáil.
Projected Seat Distribution
RTÉ's projection, based on tallies and the party's performance in key constituencies, points to the following distribution of the 23 available seats:
| Party | Projected Seats | Share | Outlook |
|---|---|---|---|
| Social Democrats | 11 | 47.8% | Largest Party |
| Fine Gael | 8 | 34.8% | 2nd |
| Sinn Féin | 2 | 8.7% | Down |
| Fianna Fáil | 2 | 8.7% | Down |
No single party is projected to reach the 12 seats required for an overall majority, meaning coalition arithmetic will once again determine the shape of the next government.

RTÉ is providing seat-by-seat coverage of the June 2026 General Election, with party totals, an interactive hexagonal map, and constituency calls updated as results are declared.
A Historic Breakthrough
The projected result would reinforce a major realignment in Irish politics. The Social Democrats, the established largest party going into this election, are now on course to extend their lead over their rivals and lead negotiations on government formation.
Party strategists had spoken cautiously of "making gains" during the campaign, but few anticipated a result that would place them clearly at the top of the table. The projection suggests strong performances in both Dublin and provincial constituencies.
Pressure on the Rival Parties
Fine Gael is projected to finish a strong second on eight seats, keeping them firmly in contention for a role in the next government. However, the result would represent a clear loss of their position as a leading force.
The projection is far more difficult for Sinn Féin and Fianna Fáil, each forecast to win just two seats. Both parties will be looking anxiously to the actual count in the hope that transfers and late tallies improve their standing.
