How an esports market is actually built

Slot 01A market is a set of rules, not a prediction

An esports market is a named contract: it states the series, the side, the map or maps if any are named, the handicap or threshold if there is one, and the conditions under which it settles or is voided. The price is what you pay to accept those terms. Read as a sentence, a market sounds like this: on this best-of-three, in the series, Team A must win by more than three and a half rounds for the bet to win. Everything this site describes is about constructing that sentence exactly.

This matters because the same match can carry a dozen markets that look alike on a page and settle on completely different numbers. A bet on the series winner, a bet on a map handicap, a bet on total rounds and a bet on the correct score can all be priced for one fixture and none of them is a disguised version of another. The unit in the name — series, maps, rounds — is the first thing to read and the last thing to skim. Generic odds and how a price is formed from a chance are covered in this project own companion reference on wagering odds; this site is about the structure on top of that.

If you take one idea from this page, take this: the operator sells rules about what will happen, and you can only evaluate the price of a rule you can restate. A market whose name you have not read is not a market you understand, however familiar the team names look.

• Series and map markets — a named scope of the fixture
• Handicap and totals — a fixed number to clear
• Void conditions — a stated condition that can cancel the bet
• Settlement — the authority whose declared result counts

Slot 02Series, not matches: the format is part of the bet

Esports is played in series, usually best-of-one, best-of-three or best-of-five, and the format is not a footnote — it is baked into the market. A best-of-three is won by the first team to take two maps; a best-of-five needs three. A market priced on a series winner and a market priced on a map winner are different because the series and the map are different scopes, and a totals market on maps only means what it means because of the format it names.

Two consequences follow. First, a market on a named map is conditional: in a series where maps are chosen by a veto, that map may never be played, and the market will say what happens then — usually that the bet is voided and the stake returned. Second, the format can change before the event: a tournament may switch a series from best-of-three to best-of-one, and a map handicap that needed three maps to resolve no longer makes sense. Markets that name a format are settled against that format.

Slot 03The map veto decides what is being bet on

In a series, the maps are not fixed in advance. Two teams remove and choose maps in turn — bans and picks — until the maps required by the format are settled. The last map left, played when the series goes the distance, is the decider, and neither side chose it. This process is the veto, and it runs before a single round of play. The map veto page walks through it; here the point is that the veto is what makes map-specific markets conditional.

A team strong overall can be weak on the maps that survive a veto, and a map-name market is a bet on a contest the veto has not yet shaped. That is why such markets are usually priced after the veto resolves, or offered with a void clause: if the veto removes the map, the market has nothing to settle on. When you see a map market, the veto is the mechanism standing between the name and the result.

Slot 04Handicaps, totals and the shapes of a market

Most esports markets are variations on four shapes. A match or series winner market asks only which side prevails. A handicap market fixes a margin in a stated unit — maps or rounds — and asks whether one side clears it. A totals market names a single threshold and asks only whether the count is above or below it, whoever wins. A correct score market names the exact shape of the finish, such as two maps to one.

The half-point exists so there is no push. A whole-number handicap can tie and be refunded; a handicap of 3.5 cannot tie, so either the margin clears it or the bet loses. Whether the count covers every round in the series or only those on one named map is fixed by the market, and the two can disagree: a side can clear a series-round handicap and still lose a single-map round handicap built from one bad map. The handicaps page works one through; the totals page covers counts.

Slot 05The price, and the margin inside it

A price encodes an implied probability, and betting prices are built to add up to more than one hundred per cent, because the difference is the operator margin. Two sides of a series priced at 1.85 each imply about 54 per cent apiece; add them and you have about 108 per cent, and the 8 per cent above the real line is what the operator keeps over time. This is why a correct read of a game and a profitable bet are not the same thing: the read has to beat the margin first.

Nothing about a team, a map or a roster changes this arithmetic. The margin is applied when the market is made, it is present whether you win or lose a particular bet, and it is the reason a market can price both sides sensibly and still take money out of the system. Understanding the price is a separate skill from understanding the game, and only one of them is the subject here.

Slot 06Who settles the market

A market settles on an official result, and esports results can be revised in ways that a live scoreboard does not show. A disputed round can be re-played, a protest can change an outcome, a team can forfeit, and an organiser can award a walkover. The market points to an authority — usually the tournament organiser and its published result — and settlement follows that declaration, not the picture a viewer saw mid-stream. The settlement page sets out how that works and what a re-play or a forfeit does to a market.

Because a declared result can arrive after the apparent finish, a market can be left open longer than the play itself. That is not an error; it is the settlement rule doing its job, waiting for the record rather than the broadcast.

Slot 07Why a bet is voided

Voids are the most common surprise in esports because so many markets name a condition: a map, a format, a roster, a patch. When that condition fails, the market has nothing to settle on and the bet returns the stake — not a win, not a loss. A map market when the veto removes the map, a series market when the match is awarded as a walkover, a handicap when the format changes before the event: each is a void caused by a stated condition that never came true.

• Void is not a loss A voided bet returns the stake. It is the market declining to settle, because its conditions were not met.
• The condition is in the name A market naming a map, a format or a roster carries the condition that can void it. Read those words first.
• Voids cluster around events Roster changes, abandonments, walkovers and format switches before an event are where void clauses do most of their work.

Slot 08How to read an esports market

The habit that removes most surprises is mechanical: read the market name as a sentence before you look at the price. State the series and its format, the map or maps if any are named, the side, the handicap or threshold, and the condition under which the bet is instead voided. If you cannot finish that sentence, you have not yet read the market.

• Name the scope Series, map or count — the unit in the name sets what settles the bet.
• Name the number A handicap or threshold is a fixed figure; state the margin that must be cleared.
• Name the authority A market settles on an official result, not on a scoreboard you saw.
• Name the void clause The condition that can cancel the bet is written in the name; find it before staking.
