Anytime Goalscorer: The Most Common Football Prop

## The Anytime Goalscorer Market The anytime goalscorer (ATGS) market asks: will this specific player score at least one goal in the match? It is the most popular player prop in football and one of the highest-margin markets. ## The Pricing Problem ATGS markets typically carry 20–35% effective margin across all listed players. The bookmaker prices each player independently, and the sum of all implied probabilities far exceeds 100%. **Example:** In a 11-player match, if every outfield player had a true 10% probability of scoring, the fair market would sum to 100% (10 × 10%). But the bookmaker prices each at 12–15% implied, producing a sum of 120–150%. ## The True Probability Components P(Player X scores anytime) = P(Player X plays) × P(Player X participates in ≥1 scoring chance) × P(Player X converts ≥1 chance) Each component requires distinct modelling: - **Minutes probability:** Based on injury history, current fitness, manager rotation signals - **Chance involvement:** xG involvement rate (xG per 90 minutes when playing) - **Conversion:** Non-penalty xG over/under conversion rate historically ## Where ATGS Value Exists **1. Injury news not priced in:** A player listed but with unconfirmed fitness concern — if your news sources confirm fitness while the market still shows him, the price reflects uncertainty that you have resolved. **2. High xG involvement, low goal conversion, positive regression incoming:** A player whose shots are generating high xG but converting below their historical rate is likely to see positive regression. Their ATGS price may be stale relative to their current form level. **3. New penalty takers:** When a team's penalty taker changes (through transfer, red card, or manager decision), the anytime goalscorer probabilities for both the old and new taker need substantial revision. ## Margin Reality Check Even with an identified edge, the 20–30% effective margin on ATGS markets means you need significant probability estimation advantage to profit. Consider whether singles at Pinnacle (much lower ATGS margins of ~10–15%) are preferable to standard bookmaker prices.
