Highlights

• • Away 1.44 implied probability ~69.4% vs our estimate 65% → negative EV
• • Home 2.63 implies ~38.0% but our conservative estimate ~35% → also negative EV

Pros

• + Clear market favorite with tight pricing reflects bookmaker assessment
• + Conservative stance avoids taking value-less bets in the absence of match data

Cons

• - No match-specific intel (surface, injuries, recent form, H2H) increases model uncertainty
• - Potential for undisclosed factors to shift true probability in either direction

Details

We have no external match data, so we apply a conservative market-efficiency approach. The book prices imply probabilities of ~69.4% for the away pair (1.44) and ~38.0% for the home pair (2.63) (sum = 107.4% overround). Normalizing the market gives ~64.6% for away / ~35.4% for home. Given the lack of evidence to materially move us away from the market, we estimate the true win probability for the favorite (away) at 65.0% — slightly below the market-implied 69.4% to account for bookmaker margin and uncertainty. At that estimated probability, the away price (1.44) yields EV = 0.65*1.44 - 1 = -0.064 (negative). The long shot (home) would need a true win probability above ~38.0% to be +EV at 2.63; our conservative estimate for the underdog is ~35%, so that too is negative. Therefore there is no positive expected value at the current widely-available prices.

Key factors

• • No independent match-specific data available (form, injuries, H2H) — increases uncertainty
• • Market-implied probabilities show a notable overround (~7.4%), so normalized market probability for the favorite is ~64.6%
• • Our conservative estimated true probability (65%) is slightly lower than the raw implied probability (69.4%), producing negative EV at current lines
