The World Cup did not begin as a spectacle. The first edition, in 1930, featured a modest field and was won on home soil by the host. Nearly a century later, the tournament arriving in the United States, Canada and Mexico will run to 104 matches and 48 teams. The numbers in between tell the story of a sport becoming the world's.
The slow, then sudden, expansion
For decades the World Cup was a 16-team affair — a closed circle dominated by a handful of powers. Brazil, Italy, Germany and Argentina between them lifted the trophy in most editions, and the format barely changed. Then the field opened: to 24 teams, then 32, broadening the map to include nations from every confederation.
The 2026 expansion to 48 is the largest single jump in the tournament's history. It guarantees first appearances for nations that had never come close, and gives established sides like Spain, Portugal and the Netherlands a longer, more punishing road to the final. More teams means more matches, more data, and more chances for an upset to become a record.
Goals: the rise, the fall, the plateau
If you plotted goals per match across every World Cup, you would see a striking shape. The early tournaments were wildly open — the 1954 edition remains the highest-scoring in history by average. Then came a long defensive era, as tactics tightened and the value of not losing rose. In recent decades the average has settled into a remarkably stable band, hovering around two and a half to three goals per game.
That plateau is one of football's quiet miracles. Despite fitter athletes, better pitches and bolder coaching, the scoring rate has barely moved in a generation. It is a balance struck between increasingly sophisticated attacks and equally sophisticated defences — a balance our xG Lab exists to measure.
Dynasties and the dispersal of power
For most of its history the World Cup was won by a small club of nations. Brazil's five titles still lead the way, with Germany and Italy close behind and Argentina, France, England, Spain and Uruguay completing the list of champions. Eight winners in a century is a remarkably concentrated record for a global tournament.
But power has been dispersing. France's modern dominance was built on an academy system the rest of the world has tried to copy. Spain's possession era rewrote the tactical playbook. And nations once considered makeweights — Croatia reaching a final, smaller European sides like Switzerland and Austria qualifying with ease — have closed the gap. The 48-team field will accelerate this trend, handing tournament experience to countries from Canada to Saudi Arabia.
The story of the last hundred years is not that the giants got weaker. It is that everyone else got dramatically, measurably better.
The host advantage, quantified
Hosting a World Cup has always carried an edge. Six of the first eighteen tournaments were won by the host nation, a strike rate no neutral venue could match. The roar of a home crowd, the absence of travel and the familiarity of conditions all show up in the results — and, increasingly, in the underlying numbers.
2026 complicates the picture. With three hosts spread across a continent, the United States, Canada and Mexico will each enjoy home support, but also the logistical strain of a vast tournament map. Whether that shared advantage translates into deep runs is one of the most interesting statistical questions of the next edition.
What the next century might measure
The first hundred years of the World Cup were recorded in goals, caps and trophies. The next will be recorded in something far richer: expected goals, pressing intensity, passing networks and player-tracking data captured dozens of times per second. The tournament that began as a small gathering of nations is becoming a vast, continuous experiment in what football is and how it can be understood.
For a statistics desk, that is the most exciting prospect of all. As 48 teams arrive in North America — from perennial favourites like France and Brazil to nations such as Cape Verde, Norway and New Zealand chasing their own milestones — every match will add to a dataset a century in the making. We will be reading every number.
