Could World Cup 2026 Produce the Biggest Shock in FIFA History?

The FIFA World Cup has always been football’s greatest stage for surprises. From Cameroon, stunning defending champions Argentina in 1990, to Croatia reaching the final in 2018 and Morocco becoming the first African nation to reach a World Cup semi-final in 2022, every tournament produces moments nobody saw coming.

Yet World Cup 2026 feels different.

For the first time, 48 teams will compete in a World Cup. The tournament will feature 104 matches across the United States, Canada, and Mexico, with an expanded knockout phase that allows 32 nations to reach the elimination rounds. That change alone creates more opportunities for underdogs to survive the group stage and build momentum.

The question is no longer whether there will be surprises.

The real question is whether World Cup 2026 could produce the biggest World Cup shock ever seen and crown one of the most unexpected World Cup champions in FIFA history.

What Would Qualify as the Biggest World Cup Shock?

Before discussing potential surprise winners, it is worth defining what would actually constitute a historic shock.

Football has already seen outsiders go deep into tournaments. Croatia’s run to the 2018 final was remarkable. Morocco’s semi-final appearance in Qatar was groundbreaking. However, neither team lifted the trophy.

A small number of countries have won the World Cup throughout its history, with the winners being Brazil, Germany, Italy, Argentina, France, England, Spain, and Uruguay. If there were an upset at the 2026 FIFA World Cup and a country that is not traditionally viewed as an elite nation won its first title, it would be one for the record books.

Simply reaching the final would not be enough.

Winning it all would change football history.

Why the Expanded Format Helps Underdogs

The new 48-team structure may significantly increase the chances of a surprise winner that FIFA fans never expected.

Teams are divided into 12 groups of four. The top two teams in each group qualify automatically, while the eight best third-placed teams also advance. This means 32 of the 48 participants reach the knockout rounds.

In previous tournaments, one poor performance could eliminate a contender or underdog before momentum ever developed.

Now, a nation can survive a difficult group despite a defeat and still advance.

That extra safety net benefits smaller nations more than the established powers.

This provides teams with the ability to build confidence, prevent early exit, and have an advantage in the possible knockout rounds.

History shows that when a team makes it to the knockout stages, there is no telling what can happen.

The Traditional Giants Still Dominate the Conversation

Even though there are possibilities of upsets, the favorites to win are still going to be those teams that are recognized as being among the best in the world.

The reigning champion, Argentina, still has a lot of both elite talent and experience playing in tournaments. France may have the most talented pool of players across all countries playing internationally. Spain has risen as one of the top teams in Europe, with England and Brazil continuing to be viewed as two of the best teams in the world.

These teams possess something underdogs often lack: multiple elite players in every position, extensive tournament experience, and the squad depth required to survive a long competition.

That depth may become even more important in a tournament where finalists could play eight matches rather than seven.

Still, favorites do not always win.

And several challengers are positioned to threaten the established order.

Morocco: The Blueprint Already Exists

If one nation has already proven that a shock World Cup victory is possible, it is Morocco.

Their extraordinary run in Qatar changed perceptions of what African football can achieve at the highest level.

Morocco combined tactical discipline, defensive organization, and genuine quality in attack. More importantly, they no longer carry the burden of being outsiders unfamiliar with the latter stages of major tournaments.

Many of the core players who starred in 2022 remain active, while a new generation continues to emerge.

Winning the tournament would still require overcoming several giants.

But compared to previous World Cups, the idea no longer feels impossible.

Could Japan Become the Ultimate Surprise Winner?

Few national teams have developed more consistently over the last decade than Japan.

Japan has become a regular participant in the knockout stages of major tournaments and continues producing players who thrive in Europe’s strongest leagues.

Their victories over Germany and Spain during the 2022 World Cup demonstrated that they can compete tactically and technically with elite opposition.

The challenge is taking the next step.

Can Japan defeat three or four world-class opponents consecutively in the knockout rounds?

That remains the unanswered question.

Yet among potential unexpected World Cup champions, Japan may possess one of the most balanced squads outside the traditional elite.

The Dark Horse Case for Colombia

Another intriguing candidate is Colombia.

Colombia has quietly rebuilt into one of South America’s strongest sides and has demonstrated an ability to compete with elite opponents.

Unlike some underdogs, they possess a football culture deeply familiar with high-pressure international matches.

They also benefit from a style that translates well to knockout football: technical quality, creativity, and attacking unpredictability.

If Colombia receives a favorable bracket and avoids injuries to key players, they could emerge as one of the tournament’s most dangerous outsiders.

Could a Host Nation Create History?

The three-nation host arrangement of the tournament adds another factor to the mix.

In the past, home teams have had great success winning. The nations that have had success in hosting and playing games close to home at the World Cup, such as England, France, Argentina, Germany,y and Italy, have benefited from playing games close to home.

Local support should play a key role for the co-hosts of the tournament, the United States, Canada, and Mexico.

Mexico has an extensive history of playing in World Cups and has made it to the knockout stage of every World Cup that Mexico has played in to date.

The United States has invested heavily in player development and now features a generation with substantial European experience.

Canada, meanwhile, continue their rise after returning to the World Cup stage in recent years.

None would currently rank among the leading favorites, but tournament football often rewards momentum as much as reputation.

Why Winning the World Cup Is Still Different

This is where many underdog dreams traditionally end.

Reaching a quarter-final is difficult.

Reaching a semi-final is exceptional.

Winning the entire tournament requires sustained excellence across several weeks.

The expanded format may help outsiders survive longer, but eventually, they must defeat elite teams repeatedly. The physical demands are also increasing, with finalists potentially facing eight matches across the tournament. Squad depth and injury management could become decisive factors. 

That reality still favors football’s established superpowers.

An underdog might upset one giant.

Defeating three or four in succession is a far greater challenge.

So, Could World Cup 2026 Produce the Biggest World Cup Shock?

The answer is yes—but only under very specific circumstances.

The expanded 48-team format creates more opportunities for surprise runs than any previous World Cup. More teams will reach the knockout rounds. More nations will believe they have a chance. More favorable pathways can emerge.

However, the tournament’s history reminds us that lifting the trophy is different from producing a memorable upset.

A nation such as Morocco, Japan, Colombia, Mexico, or even the United States reaching the semi-finals would be a major story.

One of them becoming world champions would be something entirely different.

It would likely surpass every previous World Cup surprise and immediately rank among the greatest shocks in sporting history.

As World Cup 2026 approaches, the favorites remain clear.

But if football has taught us anything, it is that certainty rarely survives contact with the World Cup.

And for the first time in decades, the possibility of a truly unexpected World Cup champion feels slightly more realistic than it did before.
