United Ireland Betting Odds

Updated: 1844 Politics & Current Affairs

Irish reunification has been the goal of nationalists since the island was partitioned in 1921. The Good Friday agreement declared that a united Ireland could only be achieved with the consent of the majority of people in Northern Ireland. The major bookmakers now offer betting odds on whether there will be a United Ireland and if and when a vote will take place.

United Ireland Betting and Odds

A united Ireland is gaining momentum in the north, Sinn Fein has always proposed this course. 

Betting on a United Ireland received a boost when the latest census reported that there were now more Catholics in Northern Ireland than Protestants. 

The Nationalist party seized on the results saying "historic change is happening. 

Obviously whatever religion you follow does not conclusively indicate whether you would vote for a United Ireland, but the census results are likely to be trumpeted by those who do want change.  

Election Success

Sinn Fein with 27 seats is now the largest party in Northern Ireland after the May 2022 elections.

Betting On A United Ireland

Making a bet on who a United Ireland is fairly straightforward although not all bookmakers have odds.

The Republic Of Ireland

As you can see by the Irish General Election Odds Sinn Fein is in poll position to be the largest party both North and South of the border. 

By the Nationalists seeing this level of this support in the South there will be momentum from politicians in the republic. 

Republic of Ireland Flag

There are different versions of a United Ireland being mooted in the south, but it seems many favour Northern Ireland uniting with Ireland rather than staying in the United Kingdom.

United Ireland History

Ireland was partitioned in 1921 and Northern Ireland became part of the United Kingdom. 

Nationalists who want reunification of the island have opposed this ever since its formation. 

The 1998 Good Friday agreement acknowledged the legitimacy of the desire for a united Ireland while stating that it could be achieved only with the consent of a majority of the people of the six counties in the North.
