Every World Cup produces a surprise package. Whether it’s Croatia reaching the 2018 final or Morocco making history with a semi-final run in 2022, football’s biggest tournament always throws up a nation capable of shocking the world.

With the 2026 FIFA World Cup set to be the biggest ever, featuring 48 teams across the United States, Canada and Mexico, there are more opportunities than ever for an underdog to make a serious impact.

Here are three dark horse nations that could upset the established order this summer.

1. Morocco 🇲🇦

It almost feels strange calling Morocco a dark horse after their remarkable run to the semi-finals in Qatar four years ago, but they still sit outside the group of traditional favourites.

The Atlas Lions have retained the core of the squad that stunned Spain and Portugal in 2022, while also adding more quality and experience. Led by captain Achraf Hakimi and boasting talents such as Brahim Díaz, Morocco remain one of the most tactically disciplined sides in international football. They also arrive with momentum after winning the 2025 Africa Cup of Nations.

Morocco are comfortable without possession, dangerous on the counter-attack and incredibly difficult to break down. In tournament football, that combination is often a recipe for success.

Don’t be surprised if they’re challenging for another deep run.

2. Uzbekistan 🇺🇿

Every World Cup has a debut nation that captures the imagination, and Uzbekistan could be that team in 2026.

The Central Asian nation has qualified for its first-ever World Cup after years of near misses, becoming the first country from the region to reach the tournament.

They won’t be expected to go far, which is exactly what makes them dangerous. With little pressure and plenty of belief, Uzbekistan could become one of the stories of the tournament.

3. Ecuador 🇪🇨

Ecuador often fly under the radar, but they may have one of the most balanced squads outside the elite nations.

Their qualification campaign showcased one of the strongest defences in South America, while the midfield is anchored by Chelsea star Moisés Caicedo. Ecuador combine athleticism, tactical discipline and youthful energy, making them a nightmare opponent in knockout football.

Unlike many underdogs, Ecuador have genuine tournament experience and won’t fear facing football’s biggest names. If they navigate the group stage successfully, they possess all the ingredients needed to spring a surprise in the knockout rounds.

Final Thoughts

The favourites will rightly dominate the headlines. Nations such as Argentina, France, England and Spain will all believe they can lift the trophy.

But World Cups are rarely that simple.

Morocco have already shown they can compete with the world’s best. Uzbekistan arrive with the excitement of a nation making history. Ecuador possess the balance and quality to frustrate any opponent.

If you’re looking for teams capable of turning this World Cup upside down, keep a close eye on these three nations.

Football loves an underdog — and 2026 could deliver another unforgettable story.
