Ironmouse is 26 days into Mouseathon Returns, her first big subathon since leaving VShojo, and the timer runs out October 1. Third-party tracker Streams Charts puts her 2026 peak at 168,445 subs, an estimate nobody has verified. Half the revenue goes to the Immune Deficiency Foundation. This is the home stretch of a comeback, and a live test of how much fans will pay a creator directly.
⚡ Key Takeaways
- Mouseathon Returns runs September 1 to October 1, Ironmouse's first big subathon since leaving VShojo.
- Streams Charts tracks a 2026 peak of 168,445 subs, an unverified estimate with no final count yet.
- Half the revenue goes to the Immune Deficiency Foundation, a charity personal to her as someone living with CVID.
- Her 2024 run peaked at 326,252 subs, but Kai Cenat's 1,112,947 in 2025 is the new ceiling.
- The real story is the $515,000 she said VShojo owed IDF, and the fans who raised $1M in two days in response.
- Lesson for creators: the audience is the asset, and every middleman is a cost.
What actually happened?
Mouseathon Returns went live on Twitch on September 1 with a hard stop on October 1, per Sportskeeda. The rules are classic subathon: every new sub adds time to the countdown, and the stream ends at zero. This year the calendar caps the run at about a month, no matter how hard chat pushes. Twitch even backed it with a free global Mouseathon chat badge for anyone who watched 15 minutes during the window, according to Stream Database.
Streams Charts tracks a September peak of 168,445 subs. Twitch hasn't confirmed that figure, Ironmouse hasn't either, and no final count exists yet. Half of the revenue goes to the Immune Deficiency Foundation, per Gameland. She lives with CVID, so this charity isn't a branding exercise.
Her own benchmarks are the ones to watch. In 2022 she ran 31 days and finished at 171,806 subs, per Inven Global. In 2024 she went 39 days and peaked at 326,252 (Wikipedia), and on September 30, 2024 she passed Kai Cenat as Twitch's most-subscribed streamer ever, per Dexerto. Cenat has since moved the goalposts into another zip code: Mafiathon 3 ended at 1,112,947 subs in September 2025, per Streams Charts.
| Subathon | Run | Peak subs |
|---|---|---|
| Ironmouse 2022 | 31 days | 171,806 |
| Ironmouse 2024 | 39 days | 326,252 |
| Kai Cenat, Mafiathon 3 (2025) | Ended Sept 30, 2025 | 1,112,947 |
| Ironmouse 2026 | Sept 1 to Oct 1 | 168,445 so far (unverified tracker estimate) |
Why does this matter for creators?
Because the most important number in this story isn't a sub count. It's $515,000, the amount Ironmouse said VShojo owed the Immune Deficiency Foundation in subathon money when she left the agency in July 2025, per Kotaku. A record-setting fanbase generated the cash, and a middleman ended up holding it. That is the creator economy's whole problem in one sentence.
"Most importantly, the thing that hurts me the most is that the Immune Deficiency Foundation, which is the most important charity to me and also the reason why I'm here today, is owed over half a million dollars from VShojo."

Her fans didn't shrug. They pushed her Tiltify campaign for IDF past $1 million within two days, according to Siliconera. That's the lesson: the audience relationship is the asset, and everything standing between a creator and her fans is a cost.
Where does this go from here?
Mouseathon wraps October 1, and the honest read is that this is a comeback lap, not a record chase. The tracked peak so far sits under both of her previous finishes, and nothing reported suggests Cenat's million-sub mark is in play. Records are the wrong scoreboard here anyway. She said as much herself in 2024.
"Records are meant to be broken. I think it's incredible and amazing if he comes back and he breaks it, because you just have to keep moving on and moving forward."

The better scoreboard is loyalty. A creator who walked away from her agency, publicly fought for charity money, and then kept a month-long timer running anyway has proven her audience follows her, not a logo. Watch what she does with that leverage once the timer hits zero.
What does Fanvault think?
Fanvault's position is simple: a creator who can move fans like this should keep as much of the money as possible and own more ways for those fans to pay. Fanvault takes an 8% platform fee, so creators keep 92%, versus 15% at Fanvue, 10% + $0.30 at Passes and about 20% at Fanfix. Every Fanvault profile also includes a storefront with auctions, buy-it-now drops and authenticated memorabilia like signed items and stream-worn apparel, the kind of one-of-ones fans want from a month-long broadcast, and a creator who's live around the clock can run the shop, DMs and orders through a chat interface in-app or on Telegram. The Ironmouse saga says the fans were never the risk, the middlemen were.
The timer ends October 1. The real question is who holds the money when it does.
