There is a “Chapter 9” of Stranger Things already, and right now there is no officially confirmed new Chapter 9/episode 9 coming as a secret finale.

Two different “Chapter 9” ideas

1. The existing Chapter Nine (Season 4)

  • Netflix already released an episode titled “Chapter Nine: The Piggyback” , which is the supersized Season 4 Vol. 2 finale that dropped on July 1, 2022.
  • That episode runs for roughly movie-length and serves as the climax of the Vecna arc setup going into the final season.

So if someone asks “is there a Chapter 9 of Stranger Things?” in terms of episode titles, the answer is yes: Season 4 has an episode literally called “Chapter Nine: The Piggyback.”

2. The rumored secret Episode 9 of Season 5

More recently, fans are talking about a “hidden Chapter 9 / Episode 9” for Season 5 – that’s a different thing.

  • After the Season 5 finale dropped on New Year’s Eve, a fan theory called “Conformity Gate” went viral, claiming the happy ending is a Vecna-made illusion and that a real, darker Episode 9 would secretly release in early January 2026.
  • Viral posts and countdown sites have pushed dates like January 7 or January 9, 2026 , but all of that is fan speculation; the domain behind one popular countdown website is not connected to Netflix, and nothing about a new episode has been officially announced.

What Netflix and the Duffers have actually said

  • Netflix has updated its official messaging to say that all episodes of Stranger Things are now streaming , signalling the story is finished on-screen.
  • The Duffer Brothers have publicly denied filming alternate endings or hiding a secret ninth episode for Season 5.
  • Instead of a surprise Chapter 9, what is coming is a behind‑the‑scenes documentary titled “One Last Adventure: The Making of Stranger Things 5,” which is set to premiere on Netflix on January 12, 2026.

Right now, that means:

  • Yes: there is an official “Chapter Nine: The Piggyback” (Season 4 finale).
  • No (for now): there is no confirmed new Chapter 9 / Episode 9 secret ending for Season 5; those rumors are fan-driven and not backed by any official announcement.

TL;DR:

  • If you mean episode titles: yes , Stranger Things already has “Chapter Nine: The Piggyback.”
  • If you mean a brand‑new, secret Episode 9 of Season 5: as of the latest updates, there is no officially confirmed Chapter 9 coming , only a making‑of documentary on January 12, 2026.
