StarCraft 2 betting 2026: 1v1 markets, series maths and where to bet
StarCraft II betting means betting on one player against another, over series that run from best-of-three to best-of-nine. Because there are no teammates, form in the race matchup and series length decide most prices. This page explains the markets, shows how a per-map edge grows over a long series and lists the bookmakers we rank for StarCraft II.

Short answer
How does StarCraft II betting work?
You bet on a 1v1 match, a single map or a map handicap. Series are long by esports standards, and a player who wins 60% of maps wins a best-of-nine about 73% of the time. Check the race matchup: a player's record against Zerg can differ a lot from the record against Protoss.

How it works
From SC2 match to bet slip in four steps
-
Check the series length
Groups often use best-of-three, playoffs best-of-five or seven, and some finals best-of-nine.
-
Check the matchup
Look at both players' results in this race matchup (for example ZvP), not their overall record.
-
Pick the market
Match winner is the cheapest; map handicap and total maps size the series; map 1 winner prices one game.
-
Compare and limit
Take the best price across sites and set a deposit limit before the first bet.
Markets Example odds
StarCraft II betting markets explained
Common StarCraft II markets, what they pay on and what they cost. Example odds for Serral vs Clem, best-of-five.
| Market | You bet on | Example odds | Margin | What it means |
|---|---|---|---|---|
| Match winner | Who wins the series. | 1.63 / 2.32 | 4.3% | the cheapest market in the example. |
| Map handicap | Serral −1.5 maps must win 3–0 or 3–1. | 2.25 / 1.60 | 6.5% | loses on a 3–2, so it pays more. |
| Total maps | Over or under 3.5 maps in a best-of-five. | 1.85 / 1.88 | 6.8% | a bet on how close the series is. |
| Map 1 winner | Winner of the first map only. | 1.72 / 2.08 | 5.9% | closest to a pure per-map chance. |
| Correct score | Exact series result, e.g. 3–1. | [varies] | [varies] | six outcomes in a best-of-five, the widest margin. |

Series maths
From a per-map chance to a series price
In 1v1 play the per-map chance is the player's edge in this matchup. Series length then multiplies it.
BO3 = p² × (3 − 2p)
BO5 = p³ × (10 − 15p + 6p²)
p = 0.60: BO5 = 68.3%, BO7 = 71.0%, BO9 = 73.3%
p = 0.55: BO9 = 62.1%
| Per map | BO1 | BO3 | BO5 | Fair odds BO3 | BO3 vs BO1 |
|---|---|---|---|---|---|
| 50% | 50.0% | 50.0% | 50.0% | 2.00 | ±0.0 pp |
| 55% | 55.0% | 57.5% | 59.3% | 1.74 | +2.5 pp |
| 60% | 60.0% | 64.8% | 68.3% | 1.54 | +4.8 pp |
| 65% | 65.0% | 71.8% | 76.5% | 1.39 | +6.8 pp |
| 70% | 70.0% | 78.4% | 83.7% | 1.28 | +8.4 pp |
| 75% | 75.0% | 84.4% | 89.6% | 1.19 | +9.4 pp |
| 80% | 80.0% | 89.6% | 94.2% | 1.12 | +9.6 pp |
Pure maths with maps treated as independent. Map choice and preparation break this in real series.

Glossary
StarCraft II betting terms
- Matchup
- The two races in a game, e.g. ZvT for Zerg against Terran. So what: form differs by matchup; check the right one.
- Mirror
- A game where both players use the same race, e.g. PvP. So what: often more volatile than cross-race games.
- Map handicap
- A map head start or deficit, e.g. −1.5 maps. So what: pays more than the match winner.
- GG
- What a player types to concede a game. So what: a map ends at the concession, not at a timer.
- Best-of-nine
- First to five maps, used in some finals. So what: the longest series and the shortest favourite prices.
StarCraft II betting FAQ
How does StarCraft II betting work?
StarCraft II is played one against one, so you bet on a player rather than a team. The main markets are match winner, map handicap, total maps and the winner of a single map. Series run from best-of-three in groups up to best-of-nine in some finals.
Why do StarCraft II favourites win so often?
A 1v1 strategy game has no teammates to cover a bad game, and top players convert small edges over long series. A player who wins 60% of maps takes a best-of-seven about 71% of the time and a best-of-nine about 73%.
Is StarCraft II still free to play?
Yes. Blizzard made the multiplayer free to play in November 2017, so new players can follow the ladder without buying the game. Betting is for adults 18+ only.
What does the race matchup mean for betting?
Each player picks Terran, Zerg or Protoss, and a player's record can differ a lot between matchups such as ZvT or PvZ. Compare the two players' results in this matchup, not only their overall form.
What does −1.5 maps mean in a StarCraft II best-of-five?
The player must win by at least two maps: 3–0 or 3–1. It pays more than the match winner because a 3–2 win loses the bet.
What were the stakes at the Esports World Cup 2025 for StarCraft II?
The event ran from 22 to 25 July 2025 in Riyadh with a $700,000 prize pool. Semi-finals were best-of-seven and the final best-of-nine (Liquipedia).
