Card Power Rankings

Rankings are based on a composite "Heat Score" (0-100) that factors in recent price movement, eBay search volume, social media mentions, auction activity, and rookie/breakout momentum. Cards can move up or down each week based on changes in these factors. The algorithm favors cards with strong multi-factor momentum over single-factor spikes.

Rankings refresh weekly, every Monday. Each week features a new set of rankings based on the previous 7 days of market activity. Daily volatility is smoothed out to show meaningful trends rather than noise.

Yes! Each card has an Agree/Disagree vote. This doesn't change the algorithmic ranking, but it shows community sentiment. If a card is ranked #5 but 80% of voters disagree, it suggests the market and the community have different views — which can be a valuable signal.

All four major sports (MLB, NBA, NFL, NHL) are included in the combined rankings. You can filter by sport to see sport-specific top 25. The most competitive category is typically football during NFL season and basketball during the NBA playoffs.

Power Rankings help identify which cards have momentum — useful for buying into trends early or selling into hype. Cards that have been in the top 10 for multiple weeks often have sustained demand, while one-week spikes might be short-lived.
