Dota 2 betting odds: live and pre-match lines

A Dota 2 odds number is the payout multiplier a bookmaker sets on a result, not the drop rate on a treasure or an in-game item. At a decimal price of 1.80, a winning 10 unit stake returns 18, which is the 10 back plus 8 profit. The lower the number, the shorter the price and the stronger the favourite.

This board shows decimal odds, the format used across European and esports books. Fractional and moneyline formats describe the same thing in different notation, so a price quoted elsewhere converts cleanly to the number here.

Prices come from more than one book, which is the point of putting them on a single board: the same series can carry a different number at each one. More about the teams and the competitive scene behind a row sits on the Dota 2 hub.

Priced boards is the number of tracked Dota 2 matches that currently carry a price on both sides, shown against the total the board tracks. A gap between the two means some fixtures are listed but not yet priced.

Avg favourite is the average implied probability of the favourite across every priced match on the board. Before averaging, each pair of prices is normalised so the two sides sum to 100%, which strips the bookmaker margin out of the comparison. A reading near 58% describes a board of mostly close series; the higher it climbs, the more the day is made up of expected wins.

Widest edge is the largest gap between the two sides on any single priced match, measured in percentage points after that same normalisation. It flags the most one-sided series currently on the board rather than describing the board as a whole, so it can move sharply when one mismatch is added or settles.

A book opens a Dota 2 price from a model built on team rating, recent results and the current patch, then moves it as money arrives and as news lands. Prices rarely sit still between opening and lock.

Before a series, roster changes move a line hardest, because a substitute invalidates the recent results the opening price was built on. Patch and meta shifts matter almost as much in Dota, since a hero rebalance can change which teams the model should favour before any of them have played a game on it.

In play, Dota moves differently from a round-based game. The draft is priced before a single creep spawns, and comeback mechanics mean a large net-worth lead is not the near-certainty the same scoreline would be elsewhere, so live prices swing further and reverse more often. Which event a series belongs to is part of reading that: the Dota 2 match schedule carries the stage and start time behind every fixture here. We run the same board for CS2 odds.
