The free trial for NBA 2K26 on Game Pass appears to be a weekend-long Free Play Days event , running from Thursday, February 5 through Sunday, February 8 in the reported promotion. That means the trial was about 3 to 4 days , depending on the exact start and end times on your console or region.

What that means

  • It’s not a permanent Game Pass inclusion in the sources I found; it was presented as a limited Free Play Days window.
  • Players who wanted to continue after the trial window ended could buy the game at a discount during the promotion.

Quick read

  • Length: roughly a weekend.
  • Window: Feb. 5 to Feb. 8.
  • Type: Free Play Days trial, not a full ongoing subscription unlock.

TL;DR: NBA 2K26’s Game Pass trial was roughly a 3-day weekend free-play period.
