For the first time since the FIFA World Rankings were introduced more than three decades ago, the world's four highest-ranked national teams have all reached the semi-finals of the FIFA World Cup.

Spain, Argentina, France and England, the top four teams in FIFA's latest rankings have lived up to their billing by surviving the expanded 48-team tournament to set up a pair of heavyweight last-four encounters that many believe represent the strongest possible semi-final lineup.

Spain will face France on Tuesday in Dallas, while defending champions Argentina, ranked second, meet fourth-ranked England on Wednesday in Atlanta.

The achievement is unprecedented in World Cup history and comes in the first tournament to feature FIFA's revamped knockout draw, designed specifically for the expanded 48-team competition.

A new draw, a new outcome

Unlike previous World Cups, FIFA introduced a new bracket system for the 2026 tournament that ensured the four highest-ranked nations were placed in separate sections of the knockout draw.

Provided each team topped its respective group—as Spain, Argentina, France and England all did, they could not face one another before the semi-finals.

The governing body described the change as a way of ensuring "competitive balance" by creating "two separate pathways to the semi-finals," while preserving the possibility of blockbuster encounters in the latter stages of the tournament.

The format has delivered exactly that.

Rather than eliminating one another in the Round of 16 or quarter-finals, the world's four highest-ranked sides have all advanced to the final four, guaranteeing at least one dream final between the sport's biggest powers.

Expanded World Cup prompted change

The change became necessary because of the expansion from 32 to 48 teams.

Under the previous format, group winners were automatically kept apart until the quarter-finals, making early meetings between elite nations relatively uncommon.

However, the introduction of an additional knockout round in the 2026 tournament significantly increased the chances of group winners facing each other before the semi-finals.

That scenario played out repeatedly in this year's Round of 32, where the United States met Belgium, England faced Mexico and Switzerland took on Colombia.

Without a revised bracket, there was every chance two of the world's highest-ranked teams could have met and eliminated one another well before the tournament's closing stages.

Instead, FIFA adjusted the draw to ensure the leading seeds remained separated, much like the seeding systems used at Wimbledon and in UEFA's revamped Champions League format.

History made

The accomplishment is particularly remarkable given the World Cup's long history of upsetting the favourites.

Since the FIFA World Rankings were introduced in 1994, no tournament has featured all four highest-ranked nations in the semi-finals.

Several top-ranked teams have suffered famous early exits despite entering the tournament among the favourites.

Belgium, ranked inside FIFA's top four, failed to advance from the group stage in Qatar in 2022. Germany exited at the same stage in 2018, Spain suffered the same fate in 2014, Italy did so in 2010, while defending champions France were eliminated in the group stage in 2002.

Even in tournaments where the favourites progressed deep into the competition, one or more of the world's top-ranked teams typically stumbled before the last four.

The last time two of FIFA's top four nations met before the semi-finals was in 2010, when the Netherlands defeated Brazil in the quarter-finals.

This year, however, the tournament has unfolded almost exactly as FIFA envisioned when redesigning the draw.

Heavyweights deliver

While the revised bracket kept the favourites apart, each nation still had to earn its place among the final four.

Spain have combined youthful flair with tactical maturity, overcoming Belgium in the quarter-finals thanks to another decisive contribution from substitute Mikel Merino.

France have looked arguably the tournament's strongest side, with Kylian Mbappé leading the Golden Boot race alongside Lionel Messi as Les Bleus dispatched Morocco to reach yet another World Cup semi-final.

England needed Jude Bellingham's extra-time heroics to overcome Norway, while Argentina survived a stern examination from Switzerland before Julián Álvarez's stunning strike secured a place in the last four.

Each has followed a different path, but together they have produced a semi-final lineup worthy of football's biggest stage.

Four giants, one trophy

The semi-finals now offer two mouthwatering contests.

Spain's possession-based, youthful side will test itself against the experience and firepower of France, while England and Argentina renew one of international football's fiercest rivalries in a meeting loaded with history.

Only one of the four will lift the World Cup in New York on July 19, but regardless of who prevails, the 2026 tournament has already produced a landmark moment.

For the first time ever, the FIFA World Cup's semi-finals feature the four highest-ranked teams in the world, a scenario FIFA hoped its new format would make possible, and one that has delivered a fitting climax to the biggest World Cup in history.
