In 2022, Denise Coates — founder and CEO of Bet365 — paid herself £469 million in salary and dividends. In a single year. The company she founded with a £15 million loan in 2000 turned over £2.97 billion in that same financial year. The question every bettor should ask is simple: where does that money come from?
The margin — the invisible mechanism behind everything
Bookmakers do not rely on luck to profit. They build their earnings directly into the odds they offer, through a mechanism called the margin (also known as the vigorish or vig).
The easiest example: a fair coin has a 50% chance of landing heads and 50% tails. In a fair bet, the odds would be 2.00 for each side. A bookmaker offers 1.90/1.90. If you bet €100 on heads and €100 on tails simultaneously, you spend €200 and receive at most €190. The guaranteed €10 loss is the margin — in this case, 5%. Multiply that across millions of bettors over a year, and you have billions.
In football markets, the margin varies by event and market type:
- Major European leagues (1X2): 4% to 8%
- Lower-tier competitions: 8% to 15%
- Accumulators: the margin compounds across each selection — a 5-leg accumulator with 6% margin per leg carries a total margin exceeding 30%
- Exotic markets (first goalscorer, corners, cards): 15% to 30%
The real numbers behind the industry
Bet365 is not an anomaly — it is the industry standard at maximum scale:
- Bet365: £2.97 billion in revenue for 2021-22 (UK public filings)
- Flutter Entertainment (FanDuel, PokerStars, Paddy Power, Betfair): €9 billion in 2022
- Entain (Ladbrokes, Coral, bwin): £4 billion in 2022
- Global sports betting market: estimated at $83 billion in 2022, projected to reach $182 billion by 2030
In the UK alone, the Gambling Commission reported a Gross Gaming Yield — what bookmakers retain after paying winnings — of £14.4 billion in 2021-22. One country. One year.
Why almost all bettors lose in the long run
The margin is not a conspiracy. It is pure mathematics applied at enormous scale. And it has one direct consequence: over the long term, most bettors lose.
Consistent studies of bettor behaviour across multiple markets indicate that between 95% and 97% of bettors lose money over the long term. The 3% to 5% who profit sustainably do one thing: they find situations where the odds offered underestimate the true probability of the outcome. That has a name — value betting — and it is the only mathematically sustainable approach.
Why bookmakers restrict bettors who win
There is a revealing detail in the bookmaker model: they do not want consistently winning bettors placing bets with them. When they identify someone who wins regularly — and who is therefore finding value consistently — they reduce bet limits or suspend the account.
This behaviour confirms the logic of the system. Bookmakers profit from the mass of bettors who lose. When they encounter someone doing the opposite, they remove them from the game. It is, involuntarily, proof that value betting works.
How to reduce the impact of the margin
There is no way to eliminate the margin. But there are ways to minimise its impact:
- Favour main markets in major competitions — lower margins, higher liquidity
- Avoid accumulators for fun — they are the most profitable product for bookmakers, not for bettors
- Compare odds across bookmakers — even the difference between 1.90 and 1.95 on a market cuts the effective margin in half
- Use statistical criteria — identify situations where historical data diverges from the probabilities implied by the odds
Placar Frio analyses hundreds of matches daily using 6 statistical criteria with historically strong performance in the double chance market — an approach that searches precisely for situations where data diverges from what the odds suggest.
Gamble responsibly
Understanding the margin is not enough to win. Betting remains an activity with mathematically unfavourable odds for most participants. Never bet amounts you cannot afford to lose.
