**Stranger Things Season 5 concluded its main series run in early 2026 after a three-part rollout that wrapped with the two-hour finale “The Rightside Up” on December 31, 2025 (January 1 in some regions).** Netflix split the eight-episode final season across Thanksgiving, Christmas, and New Year’s Eve to maximize engagement, with the closing episode also receiving a limited simultaneous theatrical release in select U.S. and Canadian cinemas. The Duffer Brothers have since departed Netflix for a multi-year deal at Paramount focused on feature films, leaving the live-action Hawkins story closed while an animated prequel, *Stranger Things: Tales from ’85*, delivered two seasons in 2026. Traders are now watching for any official greenlight on additional animated installments or new franchise projects, as no further main-series episodes are in active production or scheduled.
