The duplication exploit problem in ARC Raiders has gotten bad enough that Embark Studios published a blog post with detection graphs to show players they are watching. The most recent offender, the 'stack split' exploit, was patched on July 9, 2026, but the damage to the in-game economy was already done. Here's everything you need to know about how the glitch worked, why it mattered, and what Embark is doing to players who used it.
How did the ARC Raiders stack split dupe glitch work?
The stack split exploit was frustrating precisely because it required zero technical skill. Any player on PC, Xbox, or PS5 could pull it off in seconds using nothing but their inventory screen.
Here's the exact sequence that triggered it:
- Prepare a stack of items in your inventory.
- Drag exactly half the stack onto the ground, dropping it.
- Move the remaining half-stack to a different slot in your backpack.
- Watch the dropped stack on the floor multiply.
That's the whole thing. No mods, no exploited menus, no external tools. The simplicity is what made it spread so fast across all platforms. Players would walk through ARC Raiders' maps and see others openly running the exploit mid-raid, which tells you how confident people felt doing it.

Can you get banned for duping in ARC Raiders?
Yes, and the odds are high that you will be. Embark Studios operates with what they describe as billions of data points on player behavior at any given moment. Every item interaction, every inventory movement, every drop is logged. Detecting a duplication pattern in that data is not a complex task for a team with that level of telemetry.
Embark published a blog post (linked from their official site at arcraiders.com) that included a graph specifically showing how they identify duping behavior. They did not publish that graph to inform players how detection works. They published it to make clear that they already know.
Players across social media have reported receiving permanent bans for using duplication exploits. Not temporary suspensions. Permanent removals.
Why does duping hurt ARC Raiders so much?
ARC Raiders is an extraction shooter where the economy is the game. Loot has value because it is scarce and hard to extract. When players can multiply any stack of items in seconds, that scarcity collapses. Rare materials become worthless. Crafting progression loses meaning. Players who play legitimately find themselves competing against inventories that should take hundreds of hours to build.
The knock-on effect is a player retention problem. Legitimate players notice the broken economy and stop engaging with progression systems. Some quit entirely. The dupers themselves often get banned and leave too. The result is a shrinking player base, which is the worst outcome for a game trying to build a long-term community.

Will more ARC Raiders dupe glitches appear?
Almost certainly. After every patch that closes one exploit, a portion of the playerbase goes looking for the next one. This is a pattern across every live-service game with a meaningful economy, and ARC Raiders is no exception. Embark's approach of publishing detection data is a deterrent, but it won't stop everyone.
The smarter play is to understand that Embark's telemetry is thorough enough to catch patterns retroactively. Even if a new exploit surfaces and gets used for a few days before a patch, that window does not mean players are safe. The data exists. The bans can come after the patch.

What should you do instead of duping?
The honest answer is that legitimate progression in ARC Raiders is genuinely rewarding when you engage with its systems properly. Understanding gun modifications and upgrades matters far more than having a surplus of duplicated materials, because gear without the knowledge to use it doesn't win raids.
For players who want to go deeper into ARC Raiders' content without risking their account, the full ARC Raiders strategy guide collection covers everything from performance optimization to operation-specific tactics. There's no shortage of ways to get ahead without touching an exploit.
The bottom line is simple: Embark is watching, they have the data to prove it, and permanent bans are the confirmed consequence. The stack split exploit is gone, but the lesson it leaves behind applies to every future glitch that surfaces in ARC Raiders.
