How Pokémon sets usually behave

Value concentrates hard: across the 195 Pokémon sets we measured this on, the single top card typically holds about 16% of a set's total card value.

On average, we estimate a new Pokémon set's cards worth $1.00 or more, weighted by price, are somewhere between 20% and 40% below the set's release-week level in weeks 26 to 30 (averaged over 17 of the sets released since February 8, 2024, when our price history starts, in each of weeks 26 to 30). A card's price change from one week to the next counts only when both of those prices are $1.00 or more. The range is our estimate's uncertainty; single sets can land well outside it.

Counting each card's largest 4-week move relative to its set's average, across 74,293 cards, moves above the set outnumber moves below it about 1.5 to 1.
