Esports Betting Explained: Markets, Integrity and Legal Status

Esports means organised competitive video gaming, and betting on it has grown alongside the audience. This guide explains the markets, how match formats change the prices, the integrity problems the scene has faced, and how the legal position differs in the UK, USA, Ireland, Canada and Australia.

It is educational only. It does not suggest teams or games to back, and esports betting carries the same risk of losing money as any other betting.

Games commonly bet on

Bookmakers tend to offer markets on the biggest titles with organised professional leagues. These include first-person shooters such as Counter-Strike and Valorant, multiplayer online battle arena games such as League of Legends and Dota 2, and sports and fighting games. Which titles are available depends on the operator, the regulator and the event.

Common markets

• Match winner: which team or player wins the series.
• Map or game winner: the winner of a single map or game within a series.
• Handicap: a team starts with a deficit or head start in maps or games, as in handicap betting.
• Total maps or rounds: an over/under line on how many maps or rounds are played.
• In-game props: markets such as first kill, first objective or total kills. These are the esports version of prop bets and usually carry higher margins.
• Outrights: the winner of a tournament, which ties your money up for days or weeks. See futures and outright bets.

Why the match format matters

Many esports matches are played as a series: best of one, best of three or best of five maps. The shorter the series, the more luck matters.

Suppose, for illustration only, that Team A has a 60% chance of winning any single map and each map is independent. That is a simplification, because maps differ and teams have map preferences. Under that assumption:

• Best of one: Team A wins 60% of the time.
• Best of three (first to two): Team A wins 64.8% of the time.
• Best of five (first to three): Team A wins about 68.3% of the time.

So the same per-map edge produces a larger advantage in a longer series, and prices differ for the same two teams depending on the format. A handicap of -1.5 maps in a best of three means Team A must win 2-0, which happens 36% of the time on these figures (0.6 x 0.6). Beyond format, results also swing with roster changes, patches and travel, which is why variance is high.

Margin on an esports price

Esports markets are priced like other betting markets, with a margin. If a two-team market shows decimal odds of 1.80 and 2.00, the implied probabilities are 55.6% and 50.0%. They add to 105.6%, so the margin is about 5.6%. In-game props and outrights are often priced with wider margins, and smaller events may have limited liquidity and lower stakes.

Integrity: match-fixing and cheating

Integrity is the sector’s biggest concern. In 2010, South Korean authorities investigated a StarCraft scandal in which professional players were accused of deliberately losing matches for money linked to illegal betting. Players were banned and criminal cases followed. Later cases, including a Counter-Strike match-fixing scandal in 2015, led to bans for players and an owner.

Several factors make esports vulnerable: events are broadcast online, some tournaments are small, and a thrown map can look like an ordinary loss. In response, bodies such as the Esports Integrity Commission work with organisers and betting operators on codes of conduct and sanctions. Licensed bookmakers also share suspicious betting patterns with regulators and integrity monitors.

Another risk is betting with in-game items. Items called skins can have real-world value, and the UK Gambling Commission has said offering gambling with tradeable skins can require a licence. Unlicensed skin betting sites offer none of the protections of a regulated operator, which is part of why unlicensed sites are best avoided.

Rules by country

• United Kingdom: the Gambling Commission treats betting on esports like betting on any other event, and licensed operators may offer it. The minimum age is 18. The Commission has warned about young people betting on esports.
• United States: regulation is state by state. Some states include esports in their sports betting laws, some exclude it and some are unclear, and sources disagree on the numbers. Some states set conditions, such as all competitors being adults. Check your state regulator.
• Ireland: betting is moving to licensing under the Gambling Regulation Act 2024, run by the Gambling Regulatory Authority of Ireland. Check the regulator’s register for what a licensed operator may offer.
• Canada: provinces regulate betting. Ontario’s rules for sport and event betting cover esports, and the age is 19 in Ontario and most provinces, 18 in Alberta, Manitoba and Quebec.
• Australia: esports wagering is part of the licensed wagering framework. Licensed operators may only offer wagering, and online casino games and pokies are prohibited for people in Australia. BetStop is the national self-exclusion register.

Staying in control

Esports betting can run around the clock, across time zones, with live markets open on many matches at once. That makes it easy to lose track. Set a budget before you start and track it with the spend tracker. Anyone who finds it hard to stop can use self-exclusion.

The bottom line

Esports betting uses familiar markets, but format, thin information and integrity history make it distinctive. Longer series reduce luck without removing it, prop and outright markets carry more margin, and legal status depends on where you live and who regulates the operator. Use licensed operators only and treat any stake as money you can afford to lose.
