Gambling terms, explained straight

Sports Betting

Live betting

Live betting, also called in-play betting, is any wager placed on a sporting event after it has started and before it ends. Odds and markets update continuously as the action unfolds.

Also known as
In-play betting, in-running betting, live action betting13
How it works
Bettors place wagers online, via a bookmaker app, by phone, or in betting shops after the event begins; odds adjust in real time.14
UK regulation
The Gambling Commission defines in-play betting as betting while the event is actually taking place.12
Australia regulation
Online in-play sports betting is prohibited under the Interactive Gambling Act; in-play race and sports betting are permitted on-site or by telephone.3

Key points

  • Live betting covers bets on the final outcome, specific in-event contingencies, and subset events such as the next point or next goal.13
  • Markets and odds update dynamically as the event progresses, reflecting the current state of play.14
  • It is a placement format, not a bet type; it can include moneyline, over/under, or handicap bets placed after the start.34
  • In the UK, the Gambling Commission regulates in-play betting; in Australia, online in-play sports betting is illegal but permitted on-site or by phone.13

How live betting works

  1. An event starts, and the bookmaker opens live markets with initial odds based on the pre-match line and early action.
  2. As the event progresses, the odds update automatically — for example, a team that concedes a goal will see its odds lengthen.
  3. You select a market (e.g. next goal scorer, match winner) and place a bet through the bookmaker's website or app.
  4. The bet is accepted or rejected at the current odds; if accepted, it settles when the event or chosen contingency ends.

Live betting strategy

A common live betting strategy involves watching the event and looking for odds that overreact to a single play — for instance, a strong team trailing early may offer value if you believe they will recover. Another approach is to bet on the next point or goal in fast-paced sports like tennis or basketball, where momentum shifts quickly. No strategy ensures profit, and the fast-moving nature of live odds means decisions must be made in seconds.

Common questions

How does live betting work?

You place a wager on a sporting event after it has started. The bookmaker offers markets — such as next goal or match winner — with odds that update in real time as the action unfolds. Bets are placed online, via an app, by phone, or in a betting shop.14

Is live betting better?

Live betting is not inherently better or worse than pre-match betting. It lets you react to what you see, but odds adjust quickly and the bookmaker's margin still applies. Some bettors prefer it for the added engagement; others find it harder to make rational decisions under time pressure.

Is live betting more profitable?

No. Live betting is not more profitable than pre-match betting. The bookmaker's edge remains, and the fast-changing odds can lead to impulsive bets. Research shows in-play betting is associated with higher gambling intensity and harm, not higher returns.3
