CS2 Premier Season 5 is expected to start right after Season 4 ends, which is reported as July 6, 2026, with only a brief maintenance window before Season 5 goes live. Some sources also say Valve has not officially confirmed the exact start time, so the safest answer is: July 6, 2026, shortly after the season- end update.

Quick Scoop

  • Season 4 ends on July 6, 2026.
  • Season 5 should launch immediately after, once the update finishes rolling out.
  • There is no confirmed exact hour from Valve in the sources I found.

What that means

If you’re trying to queue Premier, the practical expectation is that Season 5 becomes available the same day Season 4 closes, after downtime.

In other words, keep an eye on the July 6 update window rather than waiting for a separately announced launch date.

Timing note

There’s some noise online about later dates, but the more direct season-end reporting points to July 6, 2026.

That makes July 6 the best current answer for “when does Premier Season 5 start CS2.”
