This market will resolve to the date when Chapter 5 becomes available for download to a majority of players who have purchased Deltarune on Steam.

Deltarune is a role-playing game developed by Toby Fox, intended to be played after completing Undertale. The game is planned to consist of seven chapters. Chapters 1 and 2 were released for free in 2018 and 2021, respectively. Chapters 3 and 4 were released on June 4, 2025, as part of a paid package. Future chapters will be available as free updates to players who have purchased the game.

The credits of Chapter 4 indicate that Chapter 5 is scheduled for release in 2026.

While the credits of Chapter 4 state a 2026 release for Chapter 5, no specific date has been provided. And of course unforeseen circumstances could cause the release to be delayed.
