Implied probability is the break-even chance this price pays for, margin included. It is not a vig-free or fair probability.
First observed is the earliest state CuratedBets recorded for this exact wager, not the book's first price. Last changed is the most recent time price, line or availability changed. Last observed is the most recent time this exact wager was seen on the sportsbook page, changed or unchanged, and it is the one the freshness label above reads. A re-read that finds no change is never counted as movement.
First observed is the earliest state CuratedBets recorded for this exact wager — not the sportsbook's first price. Last changed is the most recent time price, line or availability changed; last observed is the most recent time this exact wager was seen on the sportsbook page, changed or unchanged — the badge above reads that clock, because it says when we last saw this market rather than when it last moved. Observation times reflect the latest successful capture; CuratedBets is not a live feed. Final pregame appears only once kickoff has passed and is the last state we observed, with its lead time shown beside it.
