How much did Marathon sell, and where?

Marathon sales: 1.2 million copies, mostly on Steam

Marathon—Bungie’s new extraction shooter—has reportedly sold about 1.2 million copies so far, based on analyst estimates cited in the provided stories. The reporting also says Steam makes up roughly 70% of the player base, indicating that most buyers are on Valve’s platform.

The story framing matters: the same estimates are characterized as showing performance that falls short of what Sony and Bungie were aiming for. In other words, the figures are being used as evidence that Marathon hasn’t achieved the early commercial “splash” expected for a high-profile release.

Key details from the supplied material

• Estimated total sales: ~1.2 million copies
• Platform split (player base): ~70% on Steam
• Interpretation: The numbers are described as underwhelming relative to expectations

Why it’s important

Sales and platform distribution can influence what happens next for a live-service or ongoing multiplayer title—particularly for a game that depends on population health (queue times, matchmaking stability, and ongoing endgame content).

Even when a game’s long-term trajectory can’t be determined from early sales alone, initial commercial reception tends to affect:

• How aggressively publishers support further content and marketing
• How quickly developers iterate on matchmaking and endgame structure
• Whether analysts and investors treat the game as a durable hit or a turnaround candidate

The provided stories don’t include official Bungie sales disclosures, nor do they offer breakdowns by region or revenue—just the analyst estimate and the Steam-heavy skew.
