With World Cup 2026 set to kick off across the United States, Canada and Mexico, fans around the globe are busy making their predictions.

One of the most closely followed forecasts comes from Opta's supercomputer, which has simulated the tournament 25,000 times to estimate each team's chances of lifting football's most coveted prize.

The results place Spain at the top of the pile, but perhaps the biggest takeaway is how open this World Cup appears to be. No team won even 20 per cent of the simulations, highlighting just how competitive the race for the trophy could become.

At the other end of the spectrum, New Zealand enter the tournament as one of the outsiders. Yet the numbers suggest the All Whites may have more reason for optimism than many realise.

Why Spain Top Opta's World Cup Predictions

Spain arrive at World Cup 2026 as the team most likely to be crowned world champions.
According to Opta's simulations, La Roja lifted the trophy in 16.1 per cent of the 25,000 tournament runs, putting them narrowly ahead of France, England and Argentina.

The ranking reflects the remarkable progress Spain have made in recent years. After winning Euro 2024, they have established themselves as one of the most complete teams in international football.

Their squad combines experienced figures with an exciting new generation led by Lamine Yamal, who has quickly become one of the sport's brightest stars.

Spain's possession-based approach remains intact, but there is now a directness and attacking threat that has made them one of the most feared sides in the world.

Opta's model also favours teams with strong squad depth, and few nations can match Spain in that department.

Yet there is one important caveat.

Being favourites has rarely guaranteed success at recent World Cups.

Why Being Favourites Can Be A Dangerous Label

History suggests that entering a World Cup as the favourite can be a burden rather than an advantage.

France arrived at the 2002 World Cup as defending champions and were eliminated in the group stage. Spain suffered the same fate in 2014 after winning the previous tournament, while Germany exited at the group stage in 2018 as reigning champions.

Even Brazil, often considered tournament favourites, fell in the quarter-finals four years ago despite widespread expectations.

The margins at World Cups are incredibly small. One poor performance, one injury or one unexpected result can completely alter the course of a campaign.

That unpredictability is reflected in Opta's projections.

Despite topping the rankings, Spain still won fewer than one in every six simulations.

France, England And Argentina Remain In The Hunt

Spain may lead the projections, but they are far from clear favourites.

France sit second in Opta's rankings and once again possess one of the deepest squads in international football. Led by Kylian Mbappe, Les Bleus have reached two of the last three World Cup finals and know exactly what it takes to succeed on the biggest stage.

England are third and enter the tournament carrying significant expectations. Having consistently reached the latter stages of major tournaments over the past decade, the Three Lions will believe their long wait for major silverware can finally come to an end.

Defending champions Argentina remain firmly in contention despite the natural transition that follows any successful World Cup cycle.

With Lionel Scaloni still in charge and a squad packed with tournament experience, Argentina continue to be viewed as one of the teams most capable of going all the way.

Opta's Top 10 Favourites To Win World Cup 2026

TeamsChances of winning
Spain16.1%
France13.0%
England11.2%
Argentina10.4%
Portugal7.0%
Brazil6.6%
Germany5.1%
Netherlands3.6%
Norway3.5%
Belgium2.4%

The numbers underline just how competitive the tournament appears. Unlike previous editions, there is no dominant team entering World Cup 2026.

Which Giants Could Be Flying Under The Radar?

One of the more intriguing aspects of Opta's predictions is where certain football powers rank.

Brazil, the most successful nation in World Cup history, sit outside the top five despite their pedigree. Germany are seventh despite being four-time champions.

That does not mean either nation should be discounted.

World Cups have a habit of rewarding experience, and few countries possess as much tournament know-how as Brazil and Germany.

At the same time, Opta's model appears to favour nations that have shown greater consistency in recent years.

Portugal's position inside the top five is particularly noteworthy.

With one of the strongest squads in their history, they may enter the tournament with less pressure than some of their rivals while still possessing the quality required to make a deep run.

Could Norway Become World Cup 2026's Biggest Surprise Package?

Among the teams outside the traditional favourites, Norway stand out.

Opta ranks them ahead of Belgium and several other established football nations, reflecting growing confidence in a squad led by Erling Haaland and Martin Odegaard.

Norway have spent years waiting for a generation capable of competing on the biggest stage.
Now they finally have one.

While winning the World Cup remains unlikely, a deep run into the knockout rounds would not come as a major surprise based on the supercomputer's projections.

Every World Cup produces an unexpected contender.

Norway may be the team best positioned to fill that role in 2026.

What About New Zealand?

While Spain occupy one end of the predictions table, New Zealand find themselves at the other.
The All Whites are among the lowest-ranked teams in the tournament and arrive with little external expectation.

Yet Opta's projections offer a more encouraging picture than many fans might expect.

New Zealand have been given a 47.8 per cent chance of progressing from Group G, a section that also contains Belgium, Egypt and Iran.

That figure may appear surprising, but it highlights how balanced the group could be.
Unlike some sections dominated by multiple elite nations, Group G offers genuine opportunities for every team involved.

For New Zealand, that could be crucial.

Chris Wood And The Chance To Make History

Much of New Zealand's hopes will rest on the shoulders of captain Chris Wood.

The Nottingham Forest striker remains his country's all-time leading goalscorer and one of the most experienced players in the squad.

Wood also understands what it means to compete at a World Cup.

New Zealand's last appearance came in South Africa in 2010, where they achieved one of the tournament's most unusual records.

Despite failing to progress from the group stage, the All Whites went unbeaten, drawing against Slovakia, Italy and Paraguay.

Sixteen years later, they return hoping to take the next step.

Simply reaching the knockout rounds would represent one of the biggest achievements in the nation's football history.

Why World Cup 2026 Could Be The Most Unpredictable Tournament In Years

The most fascinating aspect of Opta's predictions is not necessarily that Spain are favourites.
It is how little separates the leading contenders.

France, England, Argentina, Portugal and Brazil all remain firmly in the hunt, while dark horses such as Norway will believe they can upset the established order.

And even teams like New Zealand have been given genuine hope of making an impact.
If the simulations are correct, World Cup 2026 could be one of the most unpredictable and competitive tournaments football has seen in decades.

The favourites may have an edge. But they are far from guaranteed success.
