Big Warhammer 40k Chaos Space Marines rumors are here as it looks like perhaps the year of Chaos may not be quite over, or at least just delayed a bit…
It’s looking like the Year of Chaos might live up to its name. Between whispers of new kits, refreshed models, and some suspicious product page disappearances, Chaos Space Marines could be about to get one of their biggest updates in years.
Grab your bolters, Huron Blackheart, Legionaries, Red Corsairs, and Iron Warriors may be set to rise again, and things are about to get interesting.
Chaos Space Marine Rumors: A Bigger Plan for the Model Range
Updated October 18th, 2025, by Rob Baer with the latest rumors.
When you connect the dots, a missing core kit, talk of upgrade sprues, narrative hints, and cross-marketing with fiction, these new Chaos Space Marines rumors may be on to something. Could this be part of the “Year of Chaos” campaign, where multiple subfactions like Red Corsairs and Iron Warriors share the spotlight through incremental releases rather than one giant wave?
A rumored November reveal at the World Championships of Warhammer event might kick things off, setting the stage for a 2026 expansion cycle that fully repositions Chaos Space Marines as a dominant force both on the tabletop and in the lore.
But even that preview may get canceled by GW as well.
Chaos Marines Rumor Engine’s Getting Juicy
So here’s where things start getting spicy. That latest rumor engine image? Yeah, it’s basically screaming Chaos. Fans are connecting the dots between it and some fresh Red Corsair units. Then there’s the wild card, the “Butcher Surgeon” that’s been floating around the rumor mill for months.
It’s got that grim, bio-twisted vibe that fits right in with Fabius Bile’s worst science project. Whether it’s a Chaos Apothecary, a Warsmith, or something nastier, it sure feels like the Dark Gods are cooking up something big.
New Huron Blackheart Model?
Rumors say Huron Blackheart is getting a brand-new model. The infamous Tyrant of Badab has been stuck with his Finecast relic for far too long, and all signs point to him finally getting a modern plastic refresh.
What makes this more than idle chatter? The supposed timing lines up with the upcoming narrative arc, one that’s said to lean into pirate themes and Chaos raids across the stars. Huron leading the charge for a Red Corsairs-centered story would make perfect sense.
GW’s even reprinting his novel, which usually happens when a model drop is around the corner.
Red Corsairs Getting Reinforcements
The chatter doesn’t stop with Huron. The Red Corsairs themselves may be set to receive new units, possibly one to three kits, to expand the faction’s raiding flavor.
Nothing points to a full-blown range overhaul, but a small expansion with themed troops or specialists would fit GW’s pattern. Think along the lines of a character release supported by a couple of new plastic kits and a narrative box to tie it all together.
If the next Warhammer reveal really is Chaos-focused, it wouldn’t be shocking to see Red Corsairs get their moment in the spotlight after years of lurking in the background. Maybe even fighting against some Aeldari pirates.
Legionaries Vanish from the Webstore
Here’s the juicy part: the Chaos Space Marines Legionaries kit is currently 404’ing on Games Workshop’s webstore. That’s right, one of the backbone Troops kits for CSM is just gone.
When GW quietly pulls a staple kit off their site, it usually means one of two things: a packaging rework or a full product refresh. Given the timing of these Chaos rumors, this disappearance feels more like a prelude than a coincidence. Veterans of the hobby know this playbook well; a sudden delisting often signals that new sprues or boxed sets are on the way.
If Legionaries are getting updated, it could tie directly into new Chaos unit customization options (more than the Kill Team Box) or upgraded sculpts to bring them up to modern standards.
Iron Warriors Rumors: Chaos Rising
One of the stronger Chaos Marine rumors points to the Iron Warriors being next in line for a faction upgrade. There’s talk of a dedicated upgrade sprue, possibly featuring new helmets, torsos, and icons, much like the Night Lords received in their Kill Team set.
There’s even a hint that they might get a new HQ or named character model, something Iron Warriors fans have been begging for since before the Horus Heresy got its reboot.
Between Huron, the Red Corsairs, and Iron Warriors rumors, it’s clear Chaos might finally get the bespoke attention Imperial Marines have enjoyed for years.
Chaos Bikes and the Next Edition
Another long-standing Chaos Space Marines rumor making a comeback is that Chaos Bikes are getting redesigned, though reportedly not until the next edition of Warhammer 40k. With 11th Edition shaping up for 2026, that timeline lines up with GW’s usual approach: let the starter set breathe, then roll out fresh kits to maintain buzz.
New Chaos Bikes would also complete a long-overdue update cycle, bringing them up to the same visual standard as newer Chaos kits like the Chosen and Possessed.
Final Thoughts: New 40k Chaos Marine Rumors
Between a vanishing Legionaries kit, fresh Huron hype, and Iron Warriors whispers, it’s hard not to feel like these Chaos Marines rumors are on to something big. Whether it’s a new plastic wave, campaign tie-ins, or a full faction spotlight, the writing’s on the wall, and it’s painted in blood and brass.
If you’ve been thinking about starting a Chaos Space Marines army or expanding an existing one, it might be time to wait just a bit longer. The Long War may finally be getting some long-overdue reinforcements.
