The next Rainbow Six Siege season (Year 11 Season 1 for Siege X) is expected to drop in early March 2026, with most reliable community and media sources pointing to around Tuesday, March 3, 2026, but Ubisoft has not yet published a hard, final live date.

Quick Scoop

  • Ubisoft is officially revealing the new Rainbow Six Siege X Year 11 roadmap and the first season during the Six Invitational 2026 on February 15, 2026, at 8 AM PT / 5 PM CET.
  • That show will confirm the exact name, content, and usually also give a “launch window” or a specific date for the new Rainbow Six Siege season.
  • Media outlets that track Siege’s schedule say the new season is typically released about two weeks after the reveal, which lines up with the first week of March 2026, likely on a Tuesday as usual.
  • One detailed breakdown specifically expects the new season to launch on March 3, 2026, based on this pattern, but labels it as an informed prediction rather than an official Ubisoft announcement.

What’s actually confirmed vs guessed?

  • Confirmed by Ubisoft:
    • Year 11 roadmap reveal on February 15, 2026, during Six Invitational in Paris.
* Year 11 is expected to begin in March 2026 (Ubisoft communications frame it as starting that month, but without a strict day yet).
  • Strong but unofficial expectations:
    • New season roughly two weeks after the reveal, following the long‑running pattern of Siege seasons.
* A Tuesday launch in early March; community and press commonly point to March 3, 2026, as the most likely candidate.

So the clean takeaway for “when is the new Rainbow Six Siege season coming out?” right now is:
Reveal on February 15, 2026; launch expected early March 2026 (very likely around March 3), but not yet officially dated day‑and‑hour by Ubisoft.

TL;DR: The new Rainbow Six Siege season will be unveiled on February 15, 2026, and, if past release patterns hold, should go live in the first week of March 2026, most likely around March 3, though Ubisoft has not publicly locked in that specific date yet.
