No one can say with certainty who will win the next Rugby World Cup, but we can talk about the most likely contenders and how people are predicting it.

Quick Scoop: Who might win the Rugby World Cup?

Several analytics projects and media pieces have tried to forecast future Rugby World Cups using rating systems or “supercomputer” simulations. These models typically lean towards traditional powers like New Zealand, South Africa, England, France and Ireland , because they combine strong historical results with deep player pools.

How people try to predict a winner

  • Some statisticians use Elo‑style rating systems (similar to chess) that update team strength after every international match, then simulate the entire World Cup thousands of times to get win probabilities.
  • Media outlets have run long‑range simulations over multiple future tournaments; one widely reported “supercomputer” forecast suggested that England would lift the Webb Ellis Cup several times in coming editions, with New Zealand and South Africa also dominating the list of projected champions.
  • These models heavily weight recent form, strength of opposition, and margins of victory, so a team on a strong multi‑year run will usually show up as a favorite.

Usual favorites and dark horses

While the exact tournament you mean isn’t specified, the same small group of nations nearly always appears at the top of prediction lists:

  • New Zealand – Historically one of the strongest sides, with high rating scores in most predictive systems.
  • South Africa – Multiple‑time champions whose physical style and big‑match experience keep their modeled win chances high.
  • England – In some long‑range simulations, they are projected to win several upcoming World Cups, reflecting strong depth and resources.
  • France – Hosts or near‑hosts in recent cycles, with a powerful domestic league feeding a talented national squad, often rated among the top contenders.
  • Ireland and other Tier‑1 teams – Rating‑based models keep them in the mix as serious semi‑final or final threats, though simulations still show a lot of uncertainty.

An example: one statistical article described using rating‑based simulations to estimate how often each team would win from a given knockout stage, highlighting that even the top favorite usually won well under half of simulated tournaments.

Why predictions are always shaky

Even the best models openly admit that tournaments are noisy and upsets are common, so they present probabilities, not guarantees. A small change—an injury to a key fly‑half, a red card, or a tricky pool—can dramatically reshape the path to the final, which is why some analysts quote Yogi Berra’s line: “It’s tough to make predictions, especially about the future.”

So, there is no definitive answer to “who will win the Rugby World Cup” , but if you go by current rating systems and multi‑tournament simulations, you’d usually be looking at one of the traditional giants—New Zealand, South Africa, England, France, or Ireland—as the most likely champions, with the understanding that rugby history is full of surprises.
