June’s Steam Top 10: Seven 1M+ Sellers

The June 2025 Steam market analysis highlights a robust period for the platform, characterized by seven titles achieving over one million copies sold. The report emphasizes the continued dominance of indie titles, particularly those featuring co-op mechanics, which benefit from high streamer visibility and social sharing. Key performers include the co-op climbing title PEAK, which reached 3.5 million sales, and Rematch, which secured 1.3 million sales on Steam alongside 563,000 copies on PlayStation. Other notable million-plus sellers in June included Elden Ring Nightreign, Stellar Blade, R.E.P.O, and Dune Awakening.

Beyond specific sales figures, the analysis explores the strategic importance of Steam wishlists for publishers and investors. Data indicates that wishlist conversion rates are highly variable but correlate positively with volume; games with over 500,000 pre-launch wishlists typically see conversion rates of 32% within the first month. The report also notes that aggressive discounting remains a highly effective lever for driving revenue in legacy titles, as evidenced by the performance of Star Wars Battlefront II and Stardew Valley during June sales events.

The methodology relies on independent estimation models rather than adjusting figures to match sporadic publisher disclosures, prioritizing data consistency and transparency. The analysis draws on a proprietary database of over 25,000 curated public milestones to benchmark accuracy across PC and console platforms. By examining cross-platform player behavior and conversion trends, the report provides a comprehensive view of the current gaming landscape, identifying both the success of new releases and the enduring market presence of established titles.
