How Magic: The Gathering sets usually behave

Value concentrates hard: across the 400 Magic: The Gathering sets we measured this on, the single top card typically holds about 8% of a set's total card value.

On average, a new Magic: The Gathering set's cards worth $0.50 or more, weighted by price, are about 32% below the set's release-week level in weeks 26 to 30 (averaged over 66 to 71 of the sets released since February 8, 2024, when our price history starts, in each of weeks 26 to 30). About 20% of that drop came in the first week after release, 60% within about 6 weeks and 80% within about 12. The level was still falling over weeks 20 to 30, and week 30 is as far as we measure, so how far it falls is not known. A card's price change from one week to the next counts only when both of those prices are $0.50 or more. Single sets can land well away from that.

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.
