How this report is made

Every number comes from daily TCGplayer market prices (near-mint, USD) stored by Tallgrass, as of the report day — nothing here uses data from after that date. The market index is chain-linked and value-weighted across every English card's regular printing, so new listings don't move it. Movers cover Scarlet & Violet and Mega Evolution cards worth at least $10 at both ends of the week that actually traded during it. Graded sales are eBay and Fanatics Collect sold listings.

Where do these Pokémon card prices come from?

TCGplayer market prices (near mint). Movers, breadth and set changes cover Scarlet & Violet and Mega Evolution sets, cards worth at least $10 on both dates (older cards trade too rarely for a week's move to mean much). Most valuable covers every era.
