"Market line (eo_market), defined"
Jul 10, 2026
The market line (
eo_market) is a single, de-vigged consensus probability for a CS2 match, derived from multiple bookmakers and exchanges.
It is built in three steps. Prices are collected from several sources. Each source is de-vigged independently to remove its margin. The median of the resulting fair probabilities becomes the published line — the median rather than the mean, because one stale or unusually wide source then cannot drag the consensus.
Two properties are deliberate. The line is published only when at least two distinct sources contribute, so it never reflects a single opinion. And no individual source is ever named, and no per-book price is ever served — only the derived aggregate.
What you get back is a market-implied win probability: a number to compare against your own model, not a recommendation.
Our own model line, eo_model, is coming soon, once it clears validation.
