Steam Halloween Sale 2026: Dates, Rules, and Prep Checklist

Steam’s Halloween sale in 2026 is called Steam Scream V Fest, and it runs October 26 at 10:00 AM Pacific through November 2, 2026. These dates are official: Valve published them in its second-half 2026 events schedule, and they match the Steam Scream V Fest page in the Steamworks docs. No guessing required this year.

The dates are the easy part. What trips developers up is eligibility, because Scream Fest is thematic and most games do not qualify, and the 30-day discount cooldown, which fest discounts do NOT get an exemption from. Seasonal sales do. There is also the small matter of October 2026 packing four official Steam events into one month. This page covers all of it, with the exact rules from the Steamworks docs as of my check on July 2, 2026.

Two details worth flagging. First, the fest start is also the deadline: per the Steamworks event page, October 26 at 10:00 AM Pacific is the last moment to enter a discount or to opt out if you registered and changed your mind. Do not plan to set your discount “sometime during the fest week.” Second, this is the fifth Scream Fest, and every edition since 2022 has run from late October into the first days of November, so the 2026 window is exactly where the historical pattern said it would be.

Registration works by invitation. If your game is eligible, an automatic email arrives through Steamworks, and the themed sale events documentation says partners usually get six weeks or more to register once invited. Registration itself is one checkbox.

If you want every 2026 event in one view instead of hunting through Steamworks emails, our Steam sale calendar tracks all of them, and the full 2026 sales events guide walks through each one.

Scream Fest is a themed sale event, not a seasonal sale, and the distinction matters more than the branding suggests.

Seasonal sales (Summer, Autumn, Winter, Spring) are open to essentially every game released more than 30 days prior. Themed fests are curated by category: Valve picks a theme, determines which games qualify based on their store pages, and builds a dedicated event hub with featuring sections. The Scream Fest hub gets front-page placement on Steam for the full week, with sections for discounted titles, upcoming games still in Coming Soon, and games with demos.

That front-page hub is the actual prize. A discount during a random week reaches whoever happens to visit your page. A discount inside a fest puts you in a browsable, heavily trafficked event page where horror shoppers are actively looking for things to buy. Chris Zukowski’s analysis of Steam’s themed events found participating games regularly picking up thousands of wishlists in a fest week, with placement inside the hub driven by wishlist velocity and player interest going in.

Scream Fest is also the biggest thematic fest of the year for its genre. Horror is one of the most reliable categories on Steam, and this event is its Christmas.

The Scream V event page defines the theme as games that fall into the horror category, plus one explicit exception: games that are specifically about Halloween, regardless of genre. Valve’s examples of the exception include having “Halloween” in the title, trick-or-treating as a game feature, or a costume parade.

How does Valve decide whether your game is horror? From the themed sales documentation: “Eligibility is determined by the tags applied to your game’s store page, as well as the gameplay that is evident from how you describe and represent your game on your store page.”

The same doc adds a filter that catches a lot of borderline games: the game must be primarily about the theme. Valve’s own example is that an adventure game with a racing mini-game does not qualify for a racing sale. Translated to Scream Fest: a cozy farming sim with one spooky dungeon is not a horror game, and slapping the Horror tag on it will not change what the rest of your store page says.

Practical eligibility notes, all from the Steamworks docs:

• —A discount is not required. You can participate at full price, though each event page “will most prominently feature discounted games.” In practice, no discount means bottom-shelf placement.
• —Unreleased games can join. Coming Soon pages get their own section in the hub, which makes Scream Fest a legitimate wishlist play for a 2027 horror release.
• —Demos count. Games with demos get a section too, and a demo is how you convert hub browsers who will not buy an unknown horror game sight unseen.
• —No guaranteed placement. Valve states plainly that it cannot guarantee featuring or position within the event. Sections are driven by “heuristics like player interest and popularity,” which is a polite way of saying games entering the fest with more wishlists and velocity get the better shelves.

If your horror game’s tags are a mess, fix them before invitations go out, not after. Our tag optimizer shows you what your current tags signal, and the 2026 tag guide covers which horror-adjacent tags actually carry traffic. Store page representation matters just as much as tags here, and our horror page optimization guide covers the genre-specific conversion elements.

Short answer: no, unless your game is explicitly about Halloween.

This question comes up every year because Steam’s old Halloween sales (pre-2022) were looser, and because a lot of games have dark themes without being horror. The current rule is narrow. A grim fantasy RPG, a zombie-adjacent survival game with the wrong tags, or a thriller with tense moments will not clear the bar if the store page does not read as horror. The Halloween exception is for games where Halloween is the content, like Valve’s own examples of trick-or-treating as a mechanic or a costume parade, not for games that merely fit the mood.

Two honest options if you are borderline:

1. 01If your game genuinely is horror but your page undersells it, fix the page. Tags, short description, screenshots, and capsule all feed Valve’s eligibility read. This is worth doing regardless of the fest, since the same signals feed Steam’s recommendation engine year-round.
2. 02If your game is not horror, skip it and use the Autumn Sale instead. The Autumn Sale (October 1-8, 2026) is open to everything released 30+ days prior, and chasing a themed fest you do not fit wastes energy you could spend on events you do fit. The 2026 events calendar lists the full slate of themed fests Valve scheduled this year; one of them probably matches your actual genre.

Do not add misleading tags to squeeze in. Valve reads eligibility off your whole store page, not the tag list alone, and even if you slipped through, the fest audience would bounce off a page that is not what they came for. Mis-tagging also pollutes the traffic Steam’s recommender sends you the rest of the year.

This is where sale planning goes wrong most often, so here are the current rules from the Steamworks discounting documentation, verified July 2026:

• —A product cannot be discounted within 30 days of another discount. Seasonal sales are the only exemption.
• —Themed fests get no exemption. The themed sales doc says it flatly: “Themed Sale Events adhere to the discount cooldown, and no exceptions are possible.” A Scream Fest discount is a normal custom discount that happens to coincide with an event.
• —A product cannot be discounted for 30 days after a price increase in any currency, with zero exceptions.
• —Custom discounts run between 10% and 95%. Launch discounts are capped at 40% and must run 7 to 14 days.

Now apply that to the 2026 calendar. The Autumn Sale ends October 8 and Scream Fest starts October 26: an 18-day gap, well inside the 30-day cooldown window. Sounds like a problem. It is not, because the exemption works in your favor here: seasonal sale discounts neither trigger cooldowns nor respect them. You can discount in the Autumn Sale AND run a Scream Fest discount, because the Autumn discount does not start a cooldown clock.

What DOES block your Scream Fest discount:

• —Any custom discount ending after roughly September 26. If you run a self-serve weeklong deal in early October, you just spent your Scream Fest discount eligibility on a random week.
• —Any price increase after roughly September 26. If you are planning a price raise this year, do it in early September or wait until November.
• —A recent release. Custom discounts cannot run within 30 days of launch, so a game released in October cannot add a fest discount. A launch discount that naturally overlaps the fest window still displays, though, which makes a mid-October horror launch with a 7-14 day launch discount an interesting play.

And looking forward: a Scream Fest discount ending November 2 puts you on cooldown for custom discounts until early December, but the Winter Sale (December 17, 2026 - January 4, 2027) is seasonal and therefore unaffected. Scream plus Winter is a clean combination. The full rule set, including edge cases like bundle pricing, is in our Steam discount rules guide, and the strategic layer (how deep to cut, how often) is in the discount strategy guide.

I count four official events touching October 2026, back to back:

Scream Fest starts the same hour Next Fest ends. For an unreleased horror game, that sequencing is a gift: run your demo in October’s Next Fest, carry the momentum straight into Scream Fest’s Coming Soon section, and collect wishlists from two front-page events in a row. For a released horror game, the question is whether to discount in the Autumn Sale, Scream Fest, or both. Both is legal (see the cooldown section above); whether it is smart depends on your audience overlap. My general read: the Autumn Sale reaches everyone, Scream Fest reaches horror buyers specifically at higher intent, and a horror game with limited discount depth to spend should prioritize Scream.

One caution on stacking: shoppers who saw you at -20% on October 5 will notice you at -20% again on October 26. If you run both, consider going deeper in the second event or accepting that the fest’s value is the placement, not a second demand spike at the same price point.

For an eligible horror game, yes, and it is not close. Registration costs you nothing beyond a discount you would probably run anyway and some prep work. The return is a week of front-page adjacency in your exact genre.

The honest caveat is that outcomes inside a fest are wildly uneven, and the public numbers are community-documented rather than official. The same Zukowski write-up linked above shows results skewing heavily toward games that entered with wishlist velocity and landed featured widgets. Valve says placement follows “player interest and popularity.” So the fest amplifies momentum you bring to it; it rarely manufactures momentum from zero.

That is why the standard advice is to spend the two weeks before the fest generating your own spike — streamer outreach, a Reddit post, a trailer drop — so the fest’s heuristics catch you rising. Our guide on how to get Steam wishlists covers the pre-fest push in detail.

Work backward from the October 26, 10:00 AM Pacific deadline:

• —By early September: Confirm your Horror tag and store page representation are unambiguous. Check your Steamworks emails for the Scream V invitation and register (one checkbox at the opt-in page linked from your invitation). If you plan any price increase this year, do it now or defer to November.
• —By September 26: Last safe end date for any custom discount before the fest. After this date, run nothing self-serve until Scream starts.
• —Early October: Decide your Autumn Sale participation (October 1-8, no cooldown conflict). Refresh screenshots and capsule if your game has Halloween-appropriate content worth surfacing; seasonal capsule art is allowed and horror shoppers respond to it.
• —October 12-25: Pre-fest push. Streamer keys out, community posts scheduled, demo updated if you have one. If you are unreleased, make sure the demo carries over from Next Fest cleanly.
• —Before October 26, 10:00 AM Pacific: Discount entered in Steamworks. This is a hard deadline; there is no adding it mid-fest.
• —During the fest: Post an event or announcement so your followers get notified, and watch your traffic sources to see what the hub placement is actually sending you.

Then check what the fest did for you. Run your page through the free Steam Page Analyzer before the fest so the conversion problems are fixed while the traffic is still coming, and keep the sale calendar open when you plan the follow-up discount — the next clean window after Scream is the Winter Sale on December 17.
