The markets decide whether West Ham or Arsenal cover specific goal-margin handicaps, whether both teams score, and whether the match total crosses set thresholds.
A -1.5 handicap requires a two-goal winning margin; -2.5 needs three. BTTS requires at least one goal from each side; totals use 1.5 and 3.5 goals.
West Ham United and Arsenal players and managers determine outcomes through scoring, formations, and tactical adjustments.
The referee and VAR influence penalties and disallowed goals, while starting lineups, injuries and substitutes alter both goalscoring and defensive strength.
Recent form, head-to-head trends and the chosen starting XIs shape expected attacking intent and defensive setup.
In-game events — early goals, penalties, red cards and substitutions — shift handicaps and totals quickly, while weather, pitch condition and set-piece ability affect BTTS probability.
Lineups published about 90 minutes before kick-off reveal formations, injuries, and which forwards start.
Track early substitutions, VAR decisions and any red cards during the match, plus late fitness updates and weather/pitch reports that change scoring likelihood and market outcomes.
