Steam Next Fest is back, bringing another week of free playable demos for hundreds of upcoming PC games. For the players, this is a talent scouting window; for developers, this is one of the most concentrated discovery opportunities on the calendar. The February 2026 edition featured over 3,500 demos, a 51% increase from February 2025, reflecting how rapidly the event has grown as an indie game launch pad.
That’s great, but it’s also mean competition (Ouch). Luckily there’s a third party to help demos cut through the noise: Streamers. Live streaming has become an important part of how Next Fest operates, with content creators actively creating programming around the event and viewers specifically tuning in to see which upcoming games are worthy of their attention. In this article, we use Steam Next Fest June 2025 as a case study to explore how strong that relationship is, and whether a game’s streaming performance during demo week is a meaningful predictor of its viewership success at launch.
Steam Next Fest Drives Demo Viewership in Streaming… and Keeps Growing
To gauge live streaming’s relationship to Steam Next Fest, the Games & Demos categories on Twitch and Kick are a good start. It’s home to all titles that don’t yet have a dedicated platform category, making it a useful barometer for demo streaming activity. The time limit between shows ranges from 0.5 million to 1 million weekly viewing hours; during the weeks of Next Fest, that number doubles overall.
The surge also continues to increase: February 2024 peaked with 1.4 million hours watched, while February 2026 set a new record of 2.3 million, or an increase of about 64% in two years. The October edition consistently outperforms the June one, which tends to be a bit of a downer, perhaps because June Next Fest has to share the spotlight with Summer Game Fest and other summer entertainment (like, you know, going outside). Even the quieter June edition was able to pass the baseline comfortably, achieving between 1.3 million and 1.6 million hours watched. Streaming audiences are clearly using Next Fest as a window for talent, and that appetite is only growing.
Streamer Actively Programs Around the Event with Next Target Fest Titles
Now let’s zoom in on a specific example with Next Fest in June 2025 to get a clearer picture of how intentionally streamers are engaging with the event. By tracking streams in the Games & Demos category that include the keyword Next Fest in their title, we can separate creators who are actively programming around the festival from creators who are just streaming minor titles that week. Prior to the event, keyword flows averaged just 1-3 per day compared to a total of 500-890 daily flows in the category, a ratio of roughly 1 in 400.
When Next Fest kicked off on June 9, keyword flow jumped from 2 on the previous day to 85, then peaked at 268 on June 10. At that time, about 1 in 6 Game & Demo streams were explicitly branded Next Fest, and total streams in the category had risen to 1.5K on the same day, up from a pre-event baseline of close to 800. Both lines tell the same story: Next Fest is attracting more streamers to the category overall, and most of them are there specifically to cover Next Fest. On June 18, just two days after the event closed, keyword flow dropped back to 5, down 97% from its peak.
Creators Who Should Check Feedback: Vinesauce and the Next Regular Fest
Knowing that streamers are actively programming Next Fest is helpful; knowing which streamer is better. In June 2025, Vinesauce led the top 10 content creators based on Next Fest-related hours watched with 51.4K (more than double 2And-place Patty 24.8K). Wine sauce also ranked 10thth the most-watched streamer in Games & Demos overall during the same period, meaning his dominance on Next Fest’s dedicated chart translated into a major presence in the broader category.
The rest of the top 10 is split into two quite different profiles. Three content creators, Ezekiel_III, Billy1Kirby, and StopGameRu, indicated 100% of their Game & Demo hours watched came from the Next Fest keyword stream, and appeared solely for the event. Several others are in the 68-86% range, while WhiskeyDing0 and KekLuck are closer to 31-33%, making Next Fest’s scope a wider variety of foods. For publishers, it’s worth paying attention to streamers covering these demos: Even if you can’t (or won’t) partner with them, watching their streams can be an invaluable source of feedback for your demo. Of course, partnering is even better, which we can help with.
Most Viewed Demos From Steam Next Fest June 2025
So far we’ve looked at the Games & Demos category as a proxy for Next Fest streaming activity. But there’s another way to approach this: Looking at the games that have generated enough buzz to warrant special streaming categories on Twitch and Kick before the event starts. These are the titles coming to Next Fest with some prior momentum, and tracking their demo viewership gives us a clearer understanding of which games the streaming community is most excited about.
Star Sword led the pack during Next Fest June 2025 with 730K hours watched during the event window, about 65% more than second place Wild gate and 441K. No, I’m Not Human And Baby Steps completing the top 4 positions, both completed 300 thousand viewing hours. After that, there’s a sharp gap: Positions 5 to 10 cluster between 45K and 151K, meaning the top 4 capture most of the demo views among this group. The top distribution is a good reminder that even in the most beloved Next Fest titles, a handful of people tend to dominate the conversation.
But what happens when these games actually launch? In this case, we’re talking about an early access launch (very important for streamers) or a full release. Seven of the 10 most-watched demos at Next Fest June 2025 managed to reach 1.5 million hours watched in the first 30 days after release, which is a strong collective result by any measure. No, I’m Not Human leads all launches with 6.9 million hours watched, followed by Baby Steps at 5.7M and Clover Hole at 5.1M. Only Pioneer (281K), Hell Is Us (537K), and UFL (185K) didn’t hit that threshold, indicating that most of those demo titles translated into post-launch attention.
Demo Streaming Coverage Predicts Launch Success
To dig deeper into that demo-to-launch relationship, we took the top 50 demos based on peak concurrent players from Next Fest June 2025 that have been released in early access or full release, and ranked them based on 1) hours watched during Next Fest and 2) first 30 days post-launch (thanks GameDiscoverCo. for the help here!). Putting those two rankings against each other gives us an immediate visual sense of whether the streaming buzz during demo week actually carries over to launch.
The correlation between the two ratings reaches 0.76, which is a strong positive relationship over 50 games. Simply put: If a game performs well on live streams during Next Fest, it will likely perform similarly on live streams at launch (compared to other titles in this sample). You can combine these findings with something we’ve established in our previous investigations: Streaming awareness drives Steam wishlists, and wishlists drive sales, making Next Fest’s streaming performance a meaningful early signal on the path to full discovery. Especially for indie developers, who rarely have the marketing budget to create hype from the start, those signals are invaluable.
But there are outliers here, and we wanted to pick just one to show you how games can break out of the Steam Next Fest funk. Take Assign: This game ranked #13 during Next Fest – a great performance, don’t get me wrong, but post-launch, it was the #1 ranked game in this sample! How could they get such a big increase? In July 2025, just weeks after Next Fest, publisher AdHoc Studio announced a full partnership with Critical Role, bringing the beloved group’s voice cast and massive online community into the fold. Assignorbit ahead of its launch in October. That publicity boost turned a promising demo into a streaming juggernaut, proof that Next Fest is often just the opening step in a longer campaign.

Steam Next Fest has always been important in game discovery, but live streaming’s role in that regard continues to grow. Streaming viewers reliably double their engagement with the Games & Demos category with each edition of the event, content creators actively structure their schedules around the event, and the demos that generate the most streaming enthusiasm tend to carry that positive sentiment right into their launch. The 0.76 correlation between Next Fest streaming ratings and post-launch streaming ratings across 50 games is a strong statistical argument that demo week performance is a signal of success.
Streaming awareness builds wish lists, and wish lists drive sales. For indie developers and publishers, understanding how their game is perceived at every step can be the difference between a successful launch and one that simply disappears.

PakarPBN
A Private Blog Network (PBN) is a collection of websites that are controlled by a single individual or organization and used primarily to build backlinks to a “money site” in order to influence its ranking in search engines such as Google. The core idea behind a PBN is based on the importance of backlinks in Google’s ranking algorithm. Since Google views backlinks as signals of authority and trust, some website owners attempt to artificially create these signals through a controlled network of sites.
In a typical PBN setup, the owner acquires expired or aged domains that already have existing authority, backlinks, and history. These domains are rebuilt with new content and hosted separately, often using different IP addresses, hosting providers, themes, and ownership details to make them appear unrelated. Within the content published on these sites, links are strategically placed that point to the main website the owner wants to rank higher. By doing this, the owner attempts to pass link equity (also known as “link juice”) from the PBN sites to the target website.
The purpose of a PBN is to give the impression that the target website is naturally earning links from multiple independent sources. If done effectively, this can temporarily improve keyword rankings, increase organic visibility, and drive more traffic from search results.
