Who Is Making the Next Halo Game now has a confirmed answer: Activision will develop the next Halo title through a new purpose-built team created specifically for Halo. Xbox announced the change on September 22 as part of its wider studio reset.
The key detail in Who Is Making the Next Halo Game is that Microsoft is not simply assigning Halo to an existing Call of Duty team. Xbox says the new Halo group is separate from ongoing Call of Duty development, while a smaller Halo Studios team remains responsible for the Halo community and games already in market.

The official Xbox memo says Activision will develop the next Halo title through a new purpose-built team. Microsoft does not name that team, its leadership, its size or its location.
The same announcement does not reveal the next game’s title, release date, platform list or campaign structure.
Is Halo Studios still making Halo?
Yes, but its role changes in the answer to Who Is Making the Next Halo Game. Xbox says a smaller team at Halo Studios will continue supporting the community and current Halo games.
The next main title is the part specifically assigned to Activision’s new team.
Is a Call of Duty studio making Halo?
Not according to Xbox’s wording. The new Activision Halo team is separate from ongoing Call of Duty development, which is an important limitation when answering Who Is Making the Next Halo Game.
Microsoft does not name Treyarch, Infinity Ward, Sledgehammer Games or another existing Call of Duty studio as Halo’s developer.
Why did Xbox move Halo?
Xbox frames the wider reorganisation behind Who Is Making the Next Halo Game around fewer business units, closer alignment and focused publishing expertise. It does not provide a Halo-specific performance explanation.
It would therefore be speculation to blame one particular Halo release, sales result or internal dispute unless Microsoft says so separately.
What happens to existing Halo games?
The existing-games part of Who Is Making the Next Halo Game stays with Halo Studios. Microsoft says its smaller team will support the Halo community and titles currently in market.
The memo does not spell out individual playlists, live-service roadmaps or legacy support plans.
Does Activision own Halo now?
No ownership transfer is announced. Who Is Making the Next Halo Game is a development question, not an IP sale. Halo remains a Microsoft franchise, and Activision is part of Microsoft.
When is the next Halo game coming out?
Xbox does not give a release date while answering Who Is Making the Next Halo Game. There is also no new platform list or title in the September memo.
The only new confirmed information is the development structure: Activision’s purpose-built team leads the next title, while Halo Studios supports current games.
What else moved under Activision?
Rare and World’s Edge also move under Activision’s remit. That is why Who Is Making the Next Halo Game sits inside a broader corporate reorganisation rather than a standalone Halo announcement.

Current Halo developer status
The current answer to Who Is Making the Next Halo Game is Activision through a new purpose-built Halo team. Halo Studios remains active as a smaller support team.
Until Microsoft names the new team or unveils the game, attaching a specific Call of Duty developer would go beyond what Xbox has confirmed.
