Resolution criteria

This market resolves YES if the complete source code of Minecraft: Java Edition is released under an open source license (OSI-approved or equivalent) that permits free use, modification, and redistribution. The source code must be publicly available in its entirety, not merely select libraries or components. Resolution can be verified via official Minecraft/Microsoft announcements or the official GitHub repository.

This market resolves NO if the game remains closed-source or if only partial libraries continue to be released without the full codebase becoming open source.

Background

Original Minecraft creator Notch stated he would release the game source code as open source once sales start dying and a minimum time has passed. However, Microsoft acquired Minecraft, and the company has not committed to full open-sourcing.

In October 2018, Mojang Studios open-sourced parts of the code for Java Edition, mainly the Brigadier command engine and the Data Fixer Upper. More recently, Mojang Studios announced it will remove obfuscation from Minecraft: Java Edition starting with the first snapshot after the Mounts of Mayhem update, with all original names included by default. However, Microsoft warns that there are no changes to the license; the source is accessible, but it's not free.

Considerations

Removing obfuscation and releasing select libraries are significant steps toward accessibility but do not constitute true open-sourcing under an OSI-approved license. The distinction matters: accessible code is not the same as open source code with permissive licensing that allows free modification and redistribution.
