Marathon Reportedly Reaches 1.2 Million Copies Sold Across All Platforms, With Steam Leading the Charge
Bungie’s Marathon has reportedly reached an estimated 1.2 million copies sold across Steam, PlayStation 5, and Xbox, according to a new report from Alinea Analytics. The key detail here is that this is an estimate from a third party analytics firm, not an official sales announcement from Bungie or Sony. Even so, the figure suggests Marathon has already built a meaningful commercial base in its first few weeks, though not necessarily the breakout launch many expected from a Bungie shooter backed by PlayStation.
Alinea’s model puts the platform split heavily in PC’s favor. The report estimates roughly 800,000 copies sold on Steam, around 217,000 on PlayStation 5, and about 133,000 on Xbox. That means Steam alone accounts for just under 70 percent of the total estimated sales, making it by far the game’s most important platform so far. For a title coming from Bungie under the PlayStation Studios umbrella, that is one of the more striking takeaways from the report.
The player engagement picture is more encouraging than the raw sales debate might suggest. Alinea says Marathon peaked at 478,000 daily active users on its first Saturday and has since settled into a still respectable rhythm, with 345,000 DAUs on the day cited in the report and a weekend average of 380,000. That suggests the game may be having a harder time breaking out to a wider audience, but the players who do stick with it are showing solid early commitment.
On Steam specifically, the publicly visible numbers also show a stable core audience rather than a total collapse. SteamDB currently lists Marathon at 25,310 players live, a 24 hour peak of 39,796, and an all time peak of 88,337 concurrent users reached on March 6, 2026. The same page also shows 111,178 followers and a Very Positive review trend with an 85.30 percent SteamDB rating at the time of capture. Those figures do not tell the whole cross platform story, but they do support the idea that the PC audience remains the game’s backbone right now.
One of the more revealing parts of Alinea’s report is who exactly is playing. On Steam, 78.2 percent of Marathon players had also played Destiny 2, while the overlap is also very high on PlayStation 5 at 74.2 percent and Xbox at 82.7 percent. The report also says 36.1 percent of Steam players had played Halo: The Master Chief Collection, reinforcing the view that Marathon is currently drawing most strongly from Bungie’s legacy fanbase rather than breaking massively into a new mainstream audience.
That may end up being the central story of Marathon’s early run. The game appears to have found a dedicated niche audience, especially on Steam, but it has not yet translated Bungie’s name recognition into a giant multi platform launch on the level Sony may have wanted. At the same time, the engagement data suggests there is still a real foundation for Bungie to build on if the studio can improve onboarding, keep the active player base engaged, and widen the game’s appeal over time. That final point is an inference based on Alinea’s modeled sales and DAU data, not an official Bungie forecast.
Do you think Marathon can grow beyond Bungie’s existing fanbase, or does its early data suggest it may remain a more dedicated niche shooter rather than a huge breakout live service hit?
