Steam Market vs Third-Party Prices

The Steam Community Market usually lists UMP-45 | Mudderhigher than third-party marketplaces — but Steam sales keep the funds in your Steam wallet, while third-party sales can cash out. The spread below compares Steam's listing price with the cheapest third-party offer per wear.

WearSteam MarketCheapest Third-PartySpread
Factory New$0.78$0.53 (HaloSkins)+47%
Minimal Wear$0.05$0.02 (Buff163)+150%
Field-Tested$0.03$0.01 (Buff163)+200%
Well-Worn$0.03$0.01 (Buff163)+200%
Battle-Scarred$0.04$0.01 (Buff163)+300%

Steam takes roughly a 15% fee from the seller and balances can't be withdrawn, so a positive spread doesn't automatically mean arbitrage — it reflects the premium buyers pay for wallet-funded convenience.
