Ironmouse set a then-record for Twitch subscribers during her 2024 subathon. The Ironmouse Model Index reports a peak of 326,252 subscribers; United Talent Agency (UTA) independently confirmed the milestone, describing her total as more than 320,000. It is a historical record, not the current one: Guinness World Records lists KaiCenat with 1,095,265 subscribers in 2025.
What record did Ironmouse break?
It was Twitch’s all-time subscriber record—not a record for followers or concurrent viewers. During her September 2024 subathon, Ironmouse surpassed the previous all-time subscriber mark. UTA described the event as a 24/7 livestream that continued through the month, including while she slept.
The exact peak figure comes from the fan-maintained, work-in-progress Ironmouse Model Index, which reports 326,252 subscribers. UTA’s separate account confirms the record-breaking milestone but gives a rounded total: more than 320,000. The exact figure should therefore be understood as the Index’s event report, not as a Twitch-verified or Guinness-certified count.
How long did the 2024 subathon last?
The Ironmouse Model Index lists the third subathon as running from September 1 through October 10, 2024, and reports 39 days on stream. UTA places the record-breaking moment in September 2024.

Is Ironmouse still the Twitch subscriber record holder?
No. Ironmouse’s record was later surpassed. Guinness World Records lists KaiCenat with 1,095,265 subscribers, achieved on September 30, 2025. Guinness notes that its record listings may not update immediately, but this is the later record-holder listing available here.
| Milestone | Reported total | Date and source |
|---|---|---|
| Ironmouse’s 2024 subathon peak | 326,252 subscribers | September–October 2024; Ironmouse Model Index, a fan-maintained work-in-progress source |
| Ironmouse’s milestone, rounded confirmation | More than 320,000 subscribers | September 2024; United Talent Agency |
| Later all-time record listing | 1,095,265 subscribers | Achieved September 30, 2025; Guinness World Records lists KaiCenat |
Why the count is described in two ways
The two 2024 accounts differ in precision, not in their basic conclusion. The Model Index provides an exact peak total for the event, while UTA independently says Ironmouse surpassed the previous record with more than 320,000 subscribers. Because the exact figure is from a fan-maintained index, it is best attributed to that source rather than presented as an officially certified Twitch count.
