Steam Next Fest October 2026: Indie Demo Checklist

Steam Next Fest: October 2026 (Valve). Hover for a Voidge draft sketch of a fragment of the banner. Side quest of the Ship It on Steam series. Part 1: partner account setup. Part 3: store page assets.

Legit heads up: Steam Next Fest October 2026 runs from October 19 at 10:00 AM PDT to October 26 at 10:00 AM PDT (that is 14:00 in Brasília). It is the week Steam hands the front page to unreleased games with playable demos. If your indie demo is registered, this is the final checklist. If you missed the window, this is the patch notes for February 2027.

Systems walkthrough, sourced from Valve docs only: Steam Next Fest hub, October 2026 edition, Upcoming Steam Events, Demos. If anything here conflicts with those pages, Valve wins.

Where the timeline stands right now

The October 2026 build already passed most of its gates. Valve's own dates:

1. August 31: registration deadline (11:59 PM PDT). Also the cutoff to have marketing materials fresh for the official trailer pick.
2. September 14: demo build and store page submitted for review if you wanted the demo live for Press Preview.
3. September 28: everything required submitted for review to make the Fest itself.
4. October 8: Press Preview started at 10:00 AM PDT. Press can browse every registered game.
5. October 19: Fest starts. Your demo must be live before 10:00 AM PDT.
6. October 26: Fest ends and the Wrap-Up page with the most played demos goes live.

So if you are reading this on October 9 and you never registered: you are not in this one. Do not panic patch. Skip to the last section.

Are you even eligible? Quick sanity check

From the hub docs, a game qualifies only if all of this is true:

• The base game store page is published and public.
• It ships a publicly playable demo by the start of the Fest.
• It releases after the Fest ends. Launch during the week and you drop out.
• It has never joined a Next Fest before. One Fest per game, forever.
• It is not a prologue, chapter one or short version of something already on Steam.

Early Access and free games are fine, as long as they are still unreleased. A Steam Playtest does not disqualify you, but Valve recommends not running one during the Fest so players do not split between two builds.

The registered dev checklist (do this before Oct 19)

1. Confirm the green checkmark

Registration is done from the base game, not the demo. Open your App Landing Page in Steamworks and confirm Next Fest shows as registered. For this edition, Valve also lists the direct page: https://partner.steamgames.com/optin/sale/nextfest_october_2026/<appid>.

2. Set the demo live early

Valve says you can release the demo any time after it passes review, and strongly suggests going live at least 30 minutes before the start. My take: ship it a day early. A demo that crashes at 10:01 is a bad first impression for exactly the players you wanted.

Remember build review only checks that the game runs and has what you promised. It is not QA. After review you can still push updates, but nobody re-checks them, so do your own smoke test on a clean machine.

If your demo has its own store page, Valve says to republish the base game so the backend links the two.

3. Audit your tags and categories

The Fest page sorts games by the one or two categories you picked at registration plus your Steam tags. The first few days are randomized; after that, logged in players get personalized carousels based on what similar players are trying. Bad tags put you in the wrong lane. Compare your tags with the Developer Preview Page and fix them now.

4. Fire the wishlist email at the right time

Steam lets you send the demo release notification to your wishlisters within 14 days of the demo launch, and only once. If your demo went live months ago, that shot is already spent, Next Fest does not refill it. If your demo goes live this month, line the email up with the Fest week.

5. Livestream (optional, not mandatory)

There is a separate streams tab for participating games. Valve is clear this is optional. If you do stream, test the broadcast to your store page before the 19th. VR games need an external tool like OBS pointed at your app ID instead of SteamVR.

6. Use the official asset kit

The October 2026 page has an asset kit for your socials, and the hashtag is #SteamNextFest. Post when you are ready, link the store page, and ask for the wishlist, not the RT.

During the week

• Read your demo reviews and discussions daily. Players will tell you exactly where they quit.
• Patch crashes fast, but do not ship big untested updates mid Fest.
• Keep your store page current. Steam pulls the microtrailer from the first video on the page (six one second clips), so make sure that video is your best one.

After October 26

Valve suggests leaving the demo up after the Fest, since players get annoyed when demos vanish without warning. If you plan to pull it, say so in advance. The Wrap-Up page goes live right after the Fest, and Valve emails the games that made it, so check your inbox.

Missed October? Plan for February 2027

Next editions per Valve: February 22 to March 1, 2027 and June 14 to 21, 2027. Since you only get one Fest, pick the one closest to your launch. Work back from Valve's general timeline:

• 5 weeks before: Developer Preview opens, and the demo must be in review if you want it live for Press Preview.
• 3 weeks before: demo submitted for review, or you risk missing the Fest.
• 11 days before: Press Preview.
• 4 days before: official Next Fest trailer drops.

Before any of that you need a public store page with real assets and a trailer. That is Part 3 of the series. If generative tools touched your art, also read the AI disclosure guide first.

Patched, tested, live before 10 AM PDT. Ship it.
