Rare, the 40-year-old studio behind Sea of Thieves, has been consolidated under Activision, the Call of Duty publisher Microsoft acquired through its $68.7 billion Activision Blizzard deal. The change was confirmed in a September 22, 2026 memo on Xbox Wire titled "Continuing Our Reset," authored by Xbox Chief Content Officer Matt Booty. It is not a sale. It is an internal reorganization within Microsoft Gaming, and the distinction matters enormously to how the story should be read.
The posts began appearing on r/Seaofthieves before most players had finished their morning coffee. Headlines warning that Rare now reported to the publisher of Call of Duty. Threads filled with speculation, gallows humour, and a familiar question: is Sea of Thieves next? The anxiety is understandable. It is also, at this stage, running ahead of the confirmed facts.
What Actually Happened: The September 22 Memo, Explained
On September 22, 2026, Booty published a memo on Xbox Wire titled "Continuing Our Reset," confirming the elimination of 268 roles across Halo Studios, other first-party studios, and the Xbox Game Studios management and central functions layer.
The same restructuring consolidated Rare, alongside the Halo and Age of Empires franchises, under Activision, the Call of Duty publisher Microsoft acquired through its $68.7 billion Activision Blizzard deal, which closed in October 2023.
Here is where precision matters. Whether this represents a formal change of corporate parent or an internal reporting-line shift is genuinely unresolved. Rare's Wikipedia infobox now lists its parent as "Xbox Game Studios (2002, 2026)" and "Activision (2026, present)," suggesting a hard re-parenting. The Verge and IGN have been more careful, describing Activision as "taking on" the franchises and Rare as being "consolidated under" the label. Booty's memo, in the excerpt available, does not name Rare or Activision explicitly. The practical reading: this is an operational consolidation under the Activision label, not a confirmed sale or legal transfer of ownership. Rare remains inside Xbox.
The clearest concrete signal of Activision's new role came alongside the cuts: the next mainline Halo game will be developed by Activision. That single detail reframes the publisher from a Call of Duty factory into a franchise-operating label with remit over multiple Xbox properties.
The 268 Xbox roles sit within a broader Microsoft-wide reduction. They also follow July 2026's reset, described at the time as the most significant restructure in Xbox history, approximately 3,200 roles cut across fiscal year 2027, of which roughly 1,600 landed on July 6 alone. Four studios left Xbox for new management in that round. The September cuts are a continuation, not a new event.
Two Brutal Years: How Rare Got Here
To understand why fans are bracing, you have to look at the last two years.
Everwild, announced at X019 in 2019 after years of prototyping and repeatedly rebooted behind the scenes, was cancelled in July 2025 amid Microsoft-wide layoffs. It was Rare's only other project in active development.
Then, in October 2025, Gregg Mayles resigned. Mayles had been at Rare since 1989, 36 years, and served as Sea of Thieves' director. His departure removed one of the studio's most senior creative anchors.
Sea of Thieves itself, released in March 2018, remains Rare's most recent release. It has attracted more than 40 million players as of April 2024, expanded to PlayStation in April 2024, and continues to receive regular content updates into 2026. It is, functionally, the studio's sole active revenue driver.
Context that cuts against the doomiest readings: Microsoft's $68.7bn acquisition of Activision Blizzard closed in October 2023, making Activision one of five Xbox publishing labels. "Rare under Activision" is an internal reorganisation within Microsoft Gaming, not an external sale to a third party.
Why Fans Are Worried: Reading the r/Seaofthieves Reaction
The community response on r/Seaofthieves, a thread that accumulated thousands of upvotes within hours of the memo's publication, has centred on two threads of concern. The first draws direct parallels to Activision's stewardship of Call of Duty. The second speculates that the studio's recent content quietness, a perceived slowdown in Sea of Thieves updates, might be tied to the administrative upheaval behind the scenes.
Both are community inference, not confirmed reporting. But they are not irrational inferences either.
Activision's Call of Duty track record is well-documented: annualised releases, aggressive monetisation through battle passes and cosmetic bundles, and a live-service model that prioritises engagement metrics. Sea of Thieves is itself a live-service game, monetised through its Pirate Emporium, Plunder Pass, and seasonal content. The structural similarity makes the comparison feel plausible to players, even if it says nothing definitive about future decisions.
There is also a transmedia wrinkle. A live-action Sea of Thieves film adaptation was reported in June 2026 to be in development, with Destin Daniel Cretton producing. That asset now sits under Activision's remit. For some fans, this signals investment and confidence. For others, it reads as another sign the IP is being repositioned as a franchise asset to be managed and exploited, rather than a game to be nurtured.
The emotional core of the story is this: a 40-year-old studio with a deeply loyal community, now reporting to the label most associated in the public imagination with the industrialisation of game franchises.
The Wider Pattern: Consolidation, Not Just Reorganisation
The Rare move does not exist in isolation.
Microsoft has signalled its intention to close Ninja Theory, the Cambridge studio behind Hellblade, with a UK-mandated staff consultation under way after two deals to save the studio fell through. Combined with the four studios that left Xbox in July 2026, the picture is one of active consolidation rather than mere internal reshuffling.
The leadership backdrop has shifted dramatically in parallel. Phil Spencer retired in February 2026 after 38 years at Microsoft. Asha Sharma, an AI executive with no prior games-industry experience, succeeded him as Xbox CEO, passing over Sarah Bond, who subsequently resigned. Matt Booty now oversees all five Xbox labels, Xbox Game Studios, Bethesda, Blizzard, King, and Activision, as EVP & Chief Content Officer.
The strategic logic behind Activision's expanded remit is relatively clear. By handing Halo to Activision and placing Rare and Age of Empires under the same label, Microsoft appears to be building a franchise-operations layer, a structure designed to manage established IPs across multiple studios, rather than a publisher defined solely by one annual shooter.
The open question for Rare is whether operating under this label means more resources, cross-franchise leverage, and operational stability, or whether it places the studio on a path toward the kind of outcome Ninja Theory is currently facing.
What to Watch Next
Several concrete signals will clarify what all of this actually means.
First, whether Rare's reporting line is formalised or clarified in future Xbox communications. If Microsoft publishes an org chart or confirms a legal re-parenting, the ambiguity resolves. If silence continues, the operational-consolidation reading holds.
Second, Sea of Thieves' 2026, 2027 content cadence. Regular, substantial updates would suggest the studio's operations remain intact. A prolonged quiet period would lend weight to community fears about disruption.
Third, the Ninja Theory consultation outcome. It is the clearest available bellwether for how far Microsoft is willing to go when studios underperform or fail to find rescue deals.
Fourth, any movement on the Sea of Thieves film under its new remit, a greenlight, a director announcement, or a quiet shelving.
A Studio Carrying Everything on One Game
The gap between what is confirmed and what is feared remains wide. Fans are reacting to a real restructuring, announced in an official memo, with documented layoffs and a genuine shift in how Xbox organises its franchises. The leap from "consolidated under Activision" to "Sea of Thieves is in danger" is not yet supported by evidence.
But the anxiety is rational given the context. Two years of cancellations and departures, a leadership overhaul at the top of Xbox, and a studio with exactly one active game now sitting under a label whose reputation precedes it.
What would settle the question is not reassurance from executives. It is content cadence, staffing levels, and the fate of whatever Rare builds next. Until then, a 40-year-old studio with 40 million players and one game carrying it all now sits under a new label, and waits to see what that actually means.
