New Twitch Badges for September 2026 – The Complete Overview

September 2026 is packed: SUBtember is already running as the month opens, joined by a LEGO Batman drop, Ironmouse's Mouseathon and the launch of The Blood of Dawnwalker. This article collects every global Twitch badge that is collectable in September or starts fresh, with start and end dates. Like the August overview, it grows over the month: as soon as a new drop shows up in the archive, I add it here.

Every badge links straight to its BadgeBase page with the streamer list, collector overview and live indicator. So you never miss a start: subscribe to the iCal calendar, check the timeline or turn on the Badge Alert. The full live list lives on the active badges page.

🎉 SUBtember 2026

Twitch's annual sub promotion SUBtember has been running since August 29 and continues all through September, until October 1. It is practically identical to the last two years (source: tos.gg). Fittingly, there is the SUBtember 2026 badge. We celebrate the month on badgebase_de and are giving away Twitch Turbo on the side.

🦇 LEGO Batman: Harley Mayhem & Joker

For the release of the new LEGO DC game, Twitch is running a small badge series, announced by the LEGO DC Game. The first badge, Harley Mayhem, is paid (sub, gift or Bits) and runs from September 1 to 20. On September 12, Joker joins, until September 28. Both are tied to the LEGO Batman: The Video Game category.

🐭 Ironmouse Mouseathon

A free event badge around Ironmouse's Mouseathon: Mouseathon is available from September 1 (3 PM) until October 1. Announced by AlphaDuplo, reported in the tos.gg recap.

🐾 Pokémon: Pichu & the starters

The Pokémon chat badges from August keep running, until October 1. Pichu is free (watch 20 minutes on 3 days in a participating category); Bulbasaur, Charmander and Squirtle come one per sub or gifted sub, with 3 subs getting all three.

🩸 The Blood of Dawnwalker

For the launch of The Blood of Dawnwalker there are two badges from September 3, each until October 3: the free Launch badge for watching in the category, and the paid Supporter badge.

🐂 Resonance Minotaur: final stretch until September 23

Still around from August: the free Resonance Minotaur drops after 60 minutes in the game's Drops category and runs until September 23.

🔥 Diablo (BlizzCon)

Around BlizzCon there is the paid Diablo badge, but only in a very short window: from September 12 (10 AM) to September 13. Announced by AlphaDuplo.

🎮 DRON-E: Rainbow Six Siege

For the Wasteland Circuit event of Operation Split Fire comes the paid DRON-E badge, from September 23 to October 13, via a sub to a participating Rainbow Six Siege stream. Source: AlphaDuplo.

🎪 TwitchCon San Diego 2026: still claimable

The two ticket badges stay claimable all through September, until November 15: Taco (3-day ticket) and BeachBall (1-day ticket). The schedule is now online. All TwitchCon badges collected under #twitchcon.

What to keep in mind

Shortest windows first: Diablo runs only September 12 to 13, Harley Mayhem until September 20, Resonance Minotaur until September 23. You have longer for Pokémon and Mouseathon (until October 1) and Dawnwalker (until October 3). Get the whole month into your calendar via the iCal feed. What is currently rare shows up on the rarest list, and the 2026 leaderboard only counts badges that started this year. I collect the month's Twitch platform news, as always, in the monthly recap.
