Right now, the 2026 Six Nations is still ongoing and a champion has not yet been decided based on the latest publicly available fixtures and coverage.

As of mid‑March 2026, media and live-score sites are showing schedules, results and tables “in progress,” rather than a completed standings table naming a winner. Pre‑tournament previews and betting markets talked up France, England and Ireland as the main contenders, with France entering as defending 2025 champions, but those pieces only give odds and expectations, not a final confirmed winner.

So, if you’re seeing people ask “who won the Six Nations 2026” on forums or social media, they are either:

  • Talking speculatively about likely winners based on current form and table position.
  • Or posting early/updating threads while the last round of games is still to be played.

To get the final answer, you’ll need to check again once the last weekend’s matches are played and the official table is updated on major rugby or news sites.
