What is the rarest item in Dota 2?

Among marketable items, the scarcest right now is Honey Heist Baby Roshan with 1 listings. Truly one-off items (event-only Genuine drops, untradeable Battle Pass rewards) don't appear on the market at all, so they can't be priced or counted here.

How is rarity different from the Immortal / Arcana label?

The in-game rarity label (Common to Arcana) is a tier Valve assigns at release; it says nothing about supply. This page measures actual scarcity — how many copies are for sale — which is what drives price.
