Eleven seats are needed for a working majority.
The Social Democrats have passed the eleven-seat threshold and are projected to form a single-party majority government in the 40th Dáil.
Constituencies fill with party colour as their seats are declared, banded where the seats split. Select one for the seat-by-seat breakdown.

Twelve of twenty-one. The Social Democrats have not just topped the poll — they have cleared the majority line with a seat to spare, and the final two declarations of the night both came to them: Dublin South's second seat and the new third seat in Dublin Central.
Every administration since February was assembled after polling day rather than won on it: a minority government propped up by Sinn Féin, then a Sinn Féin coalition, then the Fianna Fáil deal. This is the first Dáil of the year in which the largest party needs nobody.
Fine Gael's six is its best return since April and a real recovery from a two-seat floor in August. On this arithmetic it buys nothing.
Seven weeks ago Sinn Féin was the largest party in the Dáil with ten seats. Tonight it has two, and both were won in the opening batches before the count turned. Every seat that changed hands in this election — in Ulster, Midlands, Dublin Central, South Leinster and both Dublin North seats — came at Sinn Féin's expense.
None of those losses went to a single rival. Four went to Fine Gael and two to the Social Democrats, which is the signature of a vote that did not transfer rather than a vote that switched sides.
This was Ireland's fifth general election of 2026, and the first to end without a smaller party holding the balance. The instability that defined the year has been answered — by handing one party everything.
