Both Teams To Score (BTTS) is a football betting market where you predict whether both teams will score at least one goal during regular time.
It is a two-outcome market:
- Yes – Both teams score at least one goal
- No – At least one team fails to score
Extra time and penalties do not count unless explicitly stated.
How It Works
If the final score is:
- 1–1 → BTTS Yes wins
- 2–1 → BTTS Yes wins
- 1–0 → BTTS No wins
- 0–0 → BTTS No wins
Both teams must score at least one goal for a Yes bet to win.
Key Characteristics
- Team-Neutral Result
You do not need to predict the winner, only whether both sides score. - Binary Market
Unlike 1X2, BTTS has only two outcomes, reducing complexity. - Correlated With Totals
BTTS is strongly related to Over/Under markets, especially Over 2.5 goals.
For example:
- High-scoring expectations increase BTTS probability.
- However, Over 2.5 can win without BTTS (e.g., 3–0).
- BTTS can win without Over 2.5 (e.g., 1–1).
Professional Considerations
Serious bettors evaluate:
- Expected goals (xG) for both teams
- Offensive and defensive efficiency
- Clean sheet frequency
- Tactical styles (high press vs low block)
- Injury status of key attackers/defenders
- Game state expectations
Key modeling question:
What is the probability that each team scores at least once?
Mathematically, if you estimate:
- Team A scoring probability = 70%
- Team B scoring probability = 65%
The joint probability is not simply additive. Correlation matters. In open matches, probabilities are positively correlated.
Implied Probability Calculation
If BTTS Yes is priced at 1.80:
Implied probability = 1 / 1.80 = 55.56%
If your model estimates 60%, there may be value.
Variance Consideration
BTTS is sensitive to:
- Early red cards
- Tactical shifts after first goal
- Defensive game plans
- One-sided mismatches
Clean sheet probability is the main driver of No outcomes.
Professional Perspective
BTTS markets are often less efficient in lower leagues where defensive metrics are less accurately priced.
However, in top leagues with high liquidity, margins are tight and pricing is sharp.
Summary
Both Teams To Score (BTTS) is a binary market where both teams must score at least one goal for a Yes bet to win.
From a professional standpoint, edge comes from accurately modeling goal-scoring probabilities for each team and identifying mispriced implied probabilities relative to your estimates.
