Overview
- Netflix and the Duffer brothers say the series ended with eight episodes and that no secret chapter exists.
- A viral fan theory dubbed Conformity Gate predicts a hidden ninth episode on Jan. 7, pointing to marketing hints, Netflix search behavior and numerology as evidence.
- An official documentary, One Last Adventure: The Making of Stranger Things 5, is set to arrive on Jan. 12, led by director Martina Radwan and produced with MakeMake Productions.
- Coverage notes a Netflix promo referencing Jan. 7, and at least one outlet reported a short YouTube behind‑the‑scenes video, a claim not widely verified by major sources.
- Cast remarks continue to fuel interpretation debates without confirming new content, including Sadie Sink sharing her own view during a Tonight Show appearance.
