The Cold Line
What Overround means in sports betting — explained in plain English.
The amount by which the implied probabilities of all outcomes add up to more than 100%. It is one way to express the bookmaker's built-in margin.
Knowing the language is step one — knowing the true price is the edge. The Cold Line’s signal desk tracks the no-vig fair number and the closing-line value behind terms like this, before the market moves.
If both sides of a bet add up to more than 100% chance, that extra is overround — the book's cushion.
−110 / −110 implies about 52.4% + 52.4% = 104.8%. Overround ≈ 4.8%.
You know what Overround means. Now see it in action: The Cold Line’s signal desk prices the no-vig fair number before the market moves — and publishes the closing-line-value receipts to prove it. A signal desk, not another tout or handicapping service.
