The most likely answer is that there is no confirmed July 2026 date yet for the teaser or trailers for Ninjago: Dragons Rising Season 4 Part 2; based on the available coverage, only the season’s general 2026 rollout and earlier Season 4 release timing are confirmed, while a Part 2 teaser/trailer date has not been officially published in the sources I could verify.

What is confirmed

  • Netflix listings and release-roundup coverage show Lego Ninjago Dragon Rising (Season 4) arriving on Netflix on April 2, 2026, which confirms Season 4 is in motion but does not confirm a Part 2 marketing schedule.
  • A later report confirms the UK drop of the first batch of Season 4 episodes on April 2, 2026, and notes that US confirmation was still not official in that coverage.

What this means for July

  • If you’re asking whether a teaser or trailer is expected in July 2026 ahead of an August 2026 Netflix premiere, that would be a reasonable marketing window, but I could not verify any official July date from the available sources.
  • In practice, animated Netflix shows often get a teaser first and a full trailer closer to release, but that timing is an expectation rather than a confirmed schedule here.

Best read on the situation

  • Confirmed: Season 4 exists and is being released in batches.
  • Not confirmed: a July 2026 teaser date for Part 2.
  • Most likely: any Part 2 teaser or trailer would be announced close to the next batch’s premiere, not months in advance.

Quick note

If you want the safest one-line answer for a post: “No official July 2026 teaser or trailer date has been confirmed yet for Ninjago: Dragons Rising Season 4 Part 2.”
