Overview
- Alinea’s modelled data shows September 2026 was Steam’s best September on record, with estimated monthly revenue of about $1.6–$1.7 billion.
- New and relaunched titles led the month: Wardogs is estimated to have earned $86.9 million, Onimusha: Way of the Sword was a top earner, and The Blood of Dawnwalker brought in roughly $26.9 million.
- Revenue was highly concentrated, with the top 500 grossing games accounting for roughly three-quarters of September’s takings and established franchises making about 79.5% of that share.
- Free‑to‑play games remained significant, comprising 25.6% of top‑100 revenue and with Counter‑Strike 2, PUBG, Dota 2 and Apex Legends combining for nearly $168 million in the month.
- Alinea reports Q3 revenue of about $5.5 billion and year‑to‑date sales of $16.5 billion (up ~13%), and it projects Steam could exceed $20 billion in 2026 if the late‑year release slate performs, though these figures are estimates rather than Valve‑confirmed totals.
