The Steam Games That Sold the Most Copies Over the Holidays

Steam experienced a record-breaking December in 2025, generating $1.6 billion in gross revenue from over 100 million players. This performance represents a 22.7% increase over December 2024, surpassing even the previous pandemic-era peak of $1.4 billion recorded in December 2020. The surge in activity was driven by a combination of holiday engagement and aggressive discounting strategies during the Steam Winter Sale, which effectively converted wishlisted titles into sales.

The analysis highlights specific top-performing titles between December 21, 2025, and January 4, 2026. ARC Raiders led the market by volume, shifting 1.2 million copies during this two-week window and reaching a milestone of 12 million total copies sold across all platforms. Other notable performers included Detroit: Become Human, which moved 993,000 copies following a record-low price point, and the co-op title PEAK, which added 779,000 copies to its total. Additional high-volume sellers included Icarus, Battlefield 6, R.E.P.O., and Slay the Spire, all of which benefited from significant price reductions.

The findings suggest that the holiday period creates a unique psychological window where consumers have increased bandwidth to engage with new content. Strategic discounting serves as a dual-purpose tool for developers: it drives immediate revenue and expands the active install base, which is particularly effective for titles preparing for sequels or console ports. By lowering the barrier to entry, publishers successfully transformed passive consumer interest into active fandom, solidifying the importance of seasonal pricing in maintaining long-term game momentum.
