A spread is the price gap between two marketplaces for the same product and size.

​
Positive Spread

When you can buy on one platform for less than you can sell on another. Example: GOAT ask 150,StockXbid150, StockX bid 170 → $20 raw spread.

​
Does Spread = Profit?

Not quite. You need to account for:
  • Seller fees — StockX ~10%, GOAT ~10-15%, eBay ~13%
  • Shipping — Cost to receive and then ship again
  • Time — Prices can move while you’re mid-trade
That’s why the fee toggle exists. Turn it on to see spreads after estimated platform fees — much more realistic.
