C4 Sticker Slot Fuels Gains for Individual Stickers as the Market Hits a 1-Year Low

Caseway AICasewaySeptember 25, 2026

The overall index fell by 3.4% to 80.1 points, its lowest level in a year. This week, Valve enabled stickers on the C4, giving players a new way to use them and driving sharp price gains for some stickers on Steam. But the events of the week do not explain the broader decline.

Pistols fell more than any other segment, down 4.5%, while Sticker | CT in Banana gained 215.2% on Steam. Knives gained 1.2 percentage points in turnover share even as their index declined, pointing to more active trading at lower prices. Rifles, by contrast, lost turnover share.

What it means

−1.7%StickersThe segment index stands at 23.8 points, a 1-year low against a high of 70.2. Gains for individual stickers after the C4 slot was introduced are visible on Steam for now; the event’s impact on the segment as a whole is still being measured.
−2.6%KnivesThe index fell to a 1-year low of 43.6 points, compared with a high of 74.3. Turnover share rose by 1.2 percentage points as prices fell, which points to active selling rather than a recovery.
−3.5%RiflesThe index hit a 1-year low of 85.2 points, against a high of 140.7. The segment’s turnover share also fell by 1.1 percentage points, as trading shifted to other categories.

Scenarios for the week

Demand concentrated in individual stickersIf demand for C4 stickers remains concentrated in a handful of items, active selling may not lift the segment index: Sticker | Starry (Holo) | Copenhagen 2024 sold more often but fell in price on Steam.
Gains spread beyond individual stickersIf demand for C4 stickers spreads to more items and price gains are confirmed on third-party marketplaces, the sticker index could move up from its 1-year low.
Knife selling continuesIf knives continue to gain turnover share while prices fall, their index could drop below its current 1-year low.

Scenarios are reasoning based on the week’s data, not financial advice.
