Steam Next Fest October 2026: 7,240 Demos and Counting

October's Steam Next Fest had more than 7,000 games, up 65% in four months and eight times its size in 2023. It has become the world's largest games show, with no venue and no tickets. Who it works for, and who it buries.

Gamescom in Cologne hosted 1,743 exhibitors this August, a record. Two months later, a festival with no hall, no tickets and no stage hosted about 7,240 games. That festival was Steam Next Fest, and in October 2026 it became, by a distance, the largest games show on the planet.

Valve's week-long event, where developers put free demos of upcoming games on Steam, now runs three times a year. The October 2026 edition included about 7,240 games according to a live count by marketing consultant Chris Zukowski, author of the How To Market A Game newsletter, up 65.2% from 4,382 in June 2026. A separate count from SteamDB, cited by GamingOnLinux, put the number of demos at 7,164. Some outlets had reported around 8,000 based on a preview two weeks earlier; developers pulled out before the start.

Eight times bigger in three years

The growth curve is steep. Zukowski's figures show:

June 2023: 887 games
October 2023: 972
June 2024: 1,805
October 2024: 3,008
June 2025: 2,645
October 2025: 2,963
February 2026: 3,536
June 2026: 4,382
October 2026: 7,240

That is roughly eight times the June 2023 figure. The cause is the flood of new games on Steam. By Zukowski's count, Steam had 15,158 demos in 2026 against about 29,300 projected releases, a ratio of 51.7%, up from about a third in 2024. Next Fest has become the default way to launch a small PC game.

Who actually wins

A festival of 7,000 games has very few winners. In Zukowski's tracking, the top 25 demos peaked at between 419 and 20,505 concurrent players. The 6,942 games ranked below 100 peaked at between zero and 94. The median top-25 game had about 5,519 followers on Steam the day before the festival; the median game outside the top 100 had 15.

The lesson is blunt. Next Fest amplifies games that already have an audience. The strongest predictor of a demo's peak in his data was the number of followers a game had beforehand, with a correlation of 0.55, and the number it gained in the week before was close behind at 0.52. Valve gives every game some randomised front-page exposure early in the week, then shifts toward the games players are actually picking.

In June 2026, the newsletter GameDiscoverCo found that even near the top, attention was getting harder to win: a game in the top 10% gained about 121 followers during the festival, down about 25% from 163 in June 2025.

The AI question

October's festival also showed how quickly generative AI has spread into small-game development. In Zukowski's data, 34.6% of games carried Valve's AI-content disclosure. The share was much lower among the leaders: 8% of the top 25, against 35% of games outside the top 100. Among the disclosures, 75.7% mentioned art or visuals.

The pattern does not prove that AI-made games are worse, but it does suggest that players, and the Steam algorithm that follows them, are not rewarding them. Strategy RPGs had the highest disclosure rates, above 50%, and platformers the lowest.

Why it matters

Next Fest is a remarkable piece of industry infrastructure: free to enter, open to anyone, and capable of turning a small team's demo into a hit. It is also, increasingly, a lottery with thousands of tickets. For developers, including the growing number of Korean indie studios on Steam, the data says the work has to happen before the festival: building wishlists for months, then using the week to convert them.

WGC's take: Valve will need to add more curation as the festival grows, or the format will start to fail the small games it was built for. The next edition is due in February 2027. Watch whether the count passes 10,000, and whether Valve changes how it surfaces demos when it does.
