Ireland v Argentina Predictions, Betting Tips and H2H 06/11/2026

The Nations Championship is here, and Ireland welcomes Argentina to the Aviva Stadium to kick off the revamped tournament in 2026. Our rugby predictions back the hosts to win 32-26 against Argentina. This will be an interesting game, but we predict Ireland will win by at least 6 points.

According to our model, Ireland has a 59% chance of winning, which is a surprise for many punters, as this squad has some of the best Irish rugby players of all time. However, recent performances have been anything but convincing, with their last three tests all coming away from home. They beat Australia 33-31 and Japan 36-20 before slumping to a 40-21 defeat to New Zealand.

While the All Blacks match is the most recent, Ireland has fared well at home, winning all three test matches in Dublin. That run includes three victories by more than seven points. The more recent run of away test matches has us worried as they scored 90 points but conceded 91. This squad is not looking as lethal as they did a couple of years ago.

Argentina is winless in their last four matches, including three defeats at home. Los Pumas have struggled against other Southern Hemisphere teams like South Africa and Australia. However, the most recent meeting with the Wallabies ended 28-28, so they will have some momentum entering the Nations Championship.

While the Argentines have not played an away game this season, they rarely receive a drubbing. They have been within seven points in three of their last five, which means handicap betting is a genuine option. Argentina +10.5 could be a great pick, especially if a couple of late penalties decide this match.

Over/under betting is always an option for international rugby matches. Our predicted line is 49.5, as four of the last six matches from both sides cleared this target. Ireland are averaging 30 points a game, which leaves plenty of room for a couple of scores from the visitors to nail this total. Over 49.5 has some real value at our online sportsbook.

However, the history between these nations is firmly green. Ireland last played Argentina in 2024 and narrowly won 22-19. Before that, it was a one-sided match, which ended 53-7. Since 2017, Ireland has faced Argentina four times at home and won all contests. We predict this winning streak will continue, but we will see a high-scoring game this Friday.

Anyone betting on the Nations Championship will know that anything can happen. Discipline could be the biggest factor, with Argentina having a rich history of overstepping the mark. The Autumn Nations Series is gone, and this new tournament has introduced more than just pride on the line. There is a league table with silverware at the end. Ireland will want to lay claim early in the proceedings. Our prediction of a home win is the best bet for this fixture, as an Argentine upset seems unlikely.
