Also known as Evens, EVS, 1/1, Even Odds

In short
Even money is a price where you win exactly what you stake. Written as 1/1, 2.00 or +100, it implies a 50% chance before any bookmaker margin is considered.
Even money means a £10 bet wins £10, returning £20. It is the pivot of every odds format:
- Fractional: 1/1 or EVS
- Decimal: 2.00
- American: +100
Above it, you win more than you risk. Below it, you risk more than you win, an odds-on price.
It does not mean a fair bet
The implied probability of even money is exactly 50%, which makes it look like a coin flip. It rarely is.
A genuine coin flip offered by a bookmaker would be priced around 1.91 on each side, not 2.00, because the overround has to go somewhere. So when a market does offer even money on both sides of a two-way proposition, either the book is unusually sharp or one of the outcomes is being underestimated.
In practice, a price of exactly 2.00 in a competitive market usually means the bookmaker rates that outcome slightly below 50%, with the margin making up the difference.
Two places the phrase misleads
Blackjack insurance. Dealers offer “even money” when you hold a natural blackjack against a dealer ace: take a guaranteed 1:1 instead of the 3:2 you would get if the dealer has no blackjack. It sounds like a sensible hedge and is a losing proposition in every standard game. Taking it costs about 4% of the hand’s value.
Roulette outside bets. Red, black, odd and even are described as even-money bets, and they pay 1:1, but the zero means your actual chance is 18/37, or 48.6%, not 50%. The payout is even money; the proposition is not.
Common questions
Is an even money bet a 50/50 chance?
Not usually. Even money implies 50% before margin, and a genuine coin flip would be priced nearer 1.91 by a bookmaker. Roulette red pays even money on an 18-in-37 chance, which is 48.65%.
Should I take even money on a blackjack?
No. It is insurance under a different name, and it costs about 4% of the hand's value. Declining it and taking 3:2 whenever the dealer has no blackjack is worth more over time.
