Which list does the market trust?

Rankings-source disagreement

MLB Pipeline, Fangraphs, and Baseball America each publish their own Top-prospect rankings. They disagree constantly. So whose list is the card market actually pricing toward? Live Spearman correlation between each source's order and the order implied by base Bowman Chrome 1st auto avg.

How the math works. For every prospect with both a base BC 1st auto avg in the daily snapshot AND a published rank from a given source, we Spearman-rank both lists and compute the correlation. 1.0 = perfect match (the source orders prospects exactly the way the market does). 0.0 = no relationship. Negative would mean the source is the opposite of the market, which has never happened in our data and would suggest something is broken.

Sample size matters. Each source ranks a different subset (BA's Top 100 vs Fangraphs Top 300 vs MLB Pipeline Top 100). The pool varies. A source can score "higher" partly because it only ranks the most expensive prospects — the easy ones to call.

This isn't a vote for any one list. All three are well-resourced public-facing efforts. Disagreement between them is where the alpha lives — see the disputed list for which players the consensus hasn't formed on yet.
