Model vs KEI vs Market

Bottom line

Research fair, handicap reprice, edge only vs market. Three layers — don't collapse them into one number.

Key points

  • Model = research fair from simulation and structure.
  • KEI = handicap reprice that folds in information the raw model may lag.
  • Market = the price you can actually bet. Edge lives only here.

Three layers, three jobs

The model answers: what does the distribution say before we argue with the board?

KEI answers: after trusted information and desk handicap, what is our actionable fair?

The market answers: what can we get paid at right now? Edge is KEI (or fair) versus that price — not versus a narrative, and not versus last week's close.

Where people get confused

  • Treating model output as a bet slip
  • Skipping KEI and calling every model/market gap "edge"
  • Chasing steam without updating fair

KosEdge keeps the layers visible so you can see whether a play is research disagreement, information reprice, or true market misprice.

  • Compare KEI to open/best on the Edge Board before you size anything. Edge Board
  • Pull sport-level KEI when you want the full fair grid. KEI Lines
