S&box Market Report — Week 23, 2026

Market Overview

Four new items pushed the tracker to 103 skins and the board printed +9.1% to $47,143, with Scientist Hazmat Yellow carrying momentum for the second week running. On the other end, Physics Gun Tshirt ate a -73.1%, which is the kind of number that usually means a single delisting reset the floor.

We're tracking 103 unique S&box skins across the Steam Community Market.
