What betting is (the basics)

Betting means paying an amount of money (the stake) to predict the outcome of an event. If you’re right, you get your stake back plus a profit calculated from the oddsyou accepted when placing the bet. If you’re wrong, you lose the stake. There’s no more to it than that — everything else is just different ways of expressing the same idea.

The odds

Odds (also called the price) are a decimal number like 2.30. They show how much you get back for every unit staked if you win, including your original stake.

Example: you bet €10 at odds of 2.30. If you win, you get back 10 × 2.30 = €23 (your net profit is €13, since the €10 was already yours). If you lose, you lose the €10.

General formula: net profit = stake × (odds − 1). The higher the odds, the bigger the profit if you win — but high odds usually mean the market considers that outcome less likely.

Favourite and underdog

The favouriteis whoever the market considers most likely to win: their odds are low (close to 1, little profit for something “expected”). The underdog is the opposite: high odds, less likely, more profit if they win. Neither is “better” in the abstract — it depends on the analysis and on whether the odds on offer make up for the real risk.

The probability behind the odds

Every price hides a probability: it’s calculated as 1 ÷ odds. Odds of 2.00 imply the market gives that outcome a 50% chance; odds of 4.00, a 25% chance. That figure never adds up to exactly 100% across a market’s options — the difference is the margin the bookmaker keeps (the overround, see the glossary).

Comparing that implied probability against your own estimate is the basis of any serious analysis: if you think the real probability of an outcome is higher than what its odds imply, there’s potential value there — what the glossary calls positive expected value (EV).

Odds are sealed, not made up

On this platform, when a tipster publishes a pick, the odds are taken automatically from the real market at the moment of publishing (see the glossary) and are locked in forever alongside the pick. Nobody enters them by hand or can change them after publishing.

This isn’t a recommendation

This guide explains how odds and profit calculations work so you understand what you see on the platform — it isn’t an invitation to bet. Betting carries real risk of losing money, and a tipster’s past results don’t guarantee future results.
