Every sportsbook line and prediction-market price reachable without paying for anything — stripped of vig, pooled into one probability per outcome. Nothing here is cached or replayed: it arrives over a WebSocket while you watch.

The probability line

Every priced outcome, placed on one axis by its pooled probability and packed so nothing hides. Dot size is how many sources priced it. A ringed dot means a betting exchange and a sportsbook both have a number on it — the only place the word disagreement means anything.

Where they disagree

Each rule spans the lowest to the highest probability any source quoted for that outcome. Dots are the individual sources; the dashed tick is the pooled number. Long rules are arguments worth reading.
