Reading a market like terrain

A prop line is not a prediction. It is a price — the number a sportsbook believes will split the money evenly between two sides. Most of the time that price is sharp. Occasionally it is not.

PeakProps exists to find the occasions.

The model is the map

We treat a prop market the way a surveyor treats ground. Build a model of where a line should sit given everything knowable — usage, pace, matchup, recent form — and you have a contour map of the market. The places where the posted line departs from the modeled line are the slopes worth walking.

An edge is the distance between where a line is and where it should be. Everything else is narrative.

What the map is not

A map is not a guarantee. It describes the terrain; it does not promise the weather on the day. A sound model still loses individual bets — variance is the cost of doing business in any market.

So we are careful about what we claim:

• We measure the gap before forming an opinion about it.
• We size conviction to the size of the gap, not the strength of a story.
• When the model has no read, we say so, instead of inventing one.

That last point is the discipline. The hardest thing to publish in this industry is nothing — and it is often the most honest thing to publish.
