Resolution Criteria
This market resolves YES if Games Workshop officially announces and releases a completely new faction for Warhammer 40,000 before January 1, 2027. A "new faction" means a previously unplayable army that receives its own Codex and model line, not just a subfaction of an existing army.
This market resolves NO if no new factions are announced and released by the end of 2026.
Background
Games Workshop has confirmed the Emperor's Children as a new standalone Chaos Space Marine faction for 2025, with their own Codex and models
The Emperor's Children do NOT count as a new faction for this market, as they are already announced
Other confirmed Codex releases for 2025 include updates for existing factions like Astra Militarum, Imperial Knights, World Eaters, Thousand Sons, and Death Guard
Games Workshop typically announces major releases several months to a year in advance
The last truly new faction introduced to Warhammer 40k was the Leagues of Votann (Squats) in 2022
Considerations
Games Workshop occasionally introduces entirely new factions based on existing lore (like the Leagues of Votann) or creates completely new additions to the universe
Speculative potential new factions from the lore include Men of Iron, Exodites, or other xenos races, but none are currently confirmed
The introduction of a new faction typically involves significant investment in model design, rules development, and lore expansion
