Steam Hit a Record $11.1B in the First Half of 2026

Steam pulled in an estimated $11.1 billion in gross game sales in the first half of 2026, its highest-ever half-year, according to research from Alinea Analytics. That is up 14.5% on the same period in 2025 and, more strikingly, up 8% on the holiday-heavy second half of last year, a period that normally wins on seasonal sales. Steam's six-month haul nearly matched its entire pandemic-peak year of 2021 ($11.4 billion) in half the time. But the most interesting number in the report is not the total. It is that old games, not new releases, are carrying the platform.

• $11.1 billion in gross H1 2026 revenue, Steam's best half-year on record, up 14.5% year over year and up 8% on holiday-heavy H2 2025.
• Back-catalogue titles now make up 79% of revenue, up from 71% two years ago; new-year releases fell from 29% of revenue in 2024 to just 21% in 2026.
• New Chinese players are the main growth engine, alongside higher game prices and a wave of viral co-op hits.
• The market's split personality in one snapshot: a $6 game (Meccha Chameleon, $71.3M) is 2026's top seller by units, while a $70 one (Forza Horizon 6, $197.6M) tops the revenue chart.

What did the H1 2026 numbers show?

Alinea Analytics, which models Steam sales because Valve does not publish financials, estimates $11.1 billion in gross revenue for January through June 2026. To scale that: Steam did more business in six months of 2026 than in all of 2020, the year the world was locked indoors buying games. Its H1 2026 total nearly equalled the whole of pandemic-peak 2021. And it beat H2 2025 by 8%, which is unusual, because the second half of a year usually wins on the Steam Autumn and Winter sales and holiday gift-buying. Momentum has not slowed since the half closed either: Alinea says Steam has banked another half-billion, taking the running 2026 total to about $11.6 billion. Over a longer horizon the growth is steep, H1 2026 is roughly 4.7 times larger than H1 2017, and full-year revenue has climbed from around $5.5 billion in 2017 to roughly $20 billion in 2025.

Why are old games driving the growth?

This is the report's real headline. The share of revenue coming from that year's new releases has fallen for three straight years: 29% in H1 2024, 27% in H1 2025, and just 21% in H1 2026. Flip it around and back-catalogue revenue has climbed from 71% to 79%. People are digging through libraries they already own, replaying games and buying older titles they missed. Part of that is the quiet return of major third-party publishers to Steam after their own-launcher experiments failed, bringing catalogues back onto the platform and managing them better. Part of it is simple economics: a well-reviewed game two years old at $20 is a safer buy than a $70 launch, and Steam's discovery and sale mechanics are tuned to surface exactly those.

Who is actually buying?

Increasingly, new players from China. Alinea credits the surge in Chinese PC gamers as the primary force expanding the global market, layered on top of higher average game prices and a run of viral co-op hits that pulled in groups of buyers at once. That combination, more players plus higher prices plus social multiplayer, compounds: co-op games sell multiple copies per friend group, and a larger, price-tolerant audience buys deeper into the catalogue. It is a healthier growth mix than a single blockbuster, because it is not dependent on any one launch landing.

What do the top sellers tell us?

The 2026 charts capture the market's split personality perfectly.

Three premium titles cleared roughly $200 million each, proof that the $70 blockbuster still works when the game lands. But the single most-purchased game of the year by units is Meccha Chameleon at a $6 price tag, which racked up $71.3 million on sheer volume. A $6 game outselling everything by copies while a $70 one tops the revenue chart is the entire modern Steam economy in one line: a barbell of cheap, viral hits and expensive prestige launches, with the fat middle increasingly served by the back-catalogue.

What it means for the market

Valve is private, so there is no ticker to trade here, but the read for the public publishers is real. If back-catalogue revenue is now 79% of Steam's take, the companies with deep, well-managed libraries, the ones that returned to Steam rather than fighting it with their own launchers, are compounding value from games they already shipped. That favours catalogue-rich publishers over studios living launch-to-launch. Forza Horizon 6's $197.6 million is a datapoint for Microsoft's gaming arm; Resident Evil Requiem is one for Capcom. The signal for investors is that PC storefront economics are shifting from hit-driven to library-driven, which rewards durable IP and back-catalogue management more than any single release window. This is factual analysis, not investment advice.

Our take

The blockbuster is not dead, but it is no longer the whole story, and that is the genuinely new thing in these numbers. A platform growing 14.5% while its newest releases shrink to a fifth of revenue is a platform whose value increasingly lives in its accumulated library, not its launch calendar. That is a more stable business than one betting each half on a handful of tentpoles, and it explains why publishers who tried to route around Steam quietly came back. The one caveat worth stating plainly: these are Alinea Analytics estimates, not audited Valve figures, because Valve discloses nothing. The direction is well-corroborated across the industry, but treat the exact dollars as a careful model, not a filing.
