Value Bets

A value bet is a selection offered at odds higher than its estimated fair odds. In probability terms, its estimated chance of winning exceeds the probability implied by the available price. If the estimate is accurate, the bet has positive expected value, often called positive EV or +EV.

Value measures an estimated pricing advantage. It does not measure how likely a selection is to win: a low-probability outcome can have a high Value percentage.

The OddsWave value bet finder lists pre-match opportunities for events starting within the next 24 hours, including matches scheduled for tomorrow. Each row shows one selection, its estimated probability, the highest available odds among the covered bookmakers and the corresponding Value.

The initial listing threshold is a Value above 3%. A positive Value below that threshold will not appear. This display threshold helps narrow the list; it does not guarantee that a selection will win or that the estimate is accurate.

OddsWave uses the same Market Probability calculation as the match details page. For each covered bookmaker with valid, complete prices for a market, the odds are converted to implied probabilities and adjusted so the probabilities of all outcomes sum to 100%. The adjusted probabilities are then averaged across the eligible bookmakers.

This produces an estimate based on market prices, rather than a guaranteed true probability. Comparisons use the same match, market, period, line and settlement rules. For example, Over 2.5 and Over 3.5 are different selections and must not be combined.

A bookmaker’s quoted implied probabilities can total more than 100% because its prices include a margin. Removing that margin creates a benchmark for comparing prices; it does not remove uncertainty from the match.

Value uses the same calculation as Best Value on the match details page: Value (%) = (available decimal odds − fair odds) ÷ fair odds × 100

For a bet that either wins or loses, this can also be written as: Value (%) = (estimated probability as a decimal × decimal odds − 1) × 100

If the estimated probability is 52.1%, fair odds are approximately 1.9194. A bookmaker offering 2.10 gives a Value of 9.41%: (0.521 × 2.10 − 1) × 100 = 9.41%

At odds of 2.06, the same probability estimate gives a Value of 7.33%. The higher price offers more value without changing the selection’s estimated chance of winning. Calculations use unrounded values; Value is displayed to two decimal places.

For a win-or-lose bet, Value represents the estimated expected net return relative to the stake, assuming the probability estimate is accurate. It is not the return on a single bet. Markets with pushes, half wins or half losses require calculations that account for their settlement rules.

• Choose a sport and market to narrow the list. Available markets depend on the selected sport and supported data.
• Sort by Highest value, Highest probability or Starting soon. The default order puts the highest Value first.
• Check the match, selection, line, estimated probability, odds and Value together.
• If several bookmakers offer the highest odds, expand the bookmaker list to see the other companies offering that price.
• Select a bookmaker and confirm the current odds, market and settlement rules on its website.
• Each selection is assessed separately. When several bookmakers offer the same highest price, they share the displayed Value. Best available means the highest valid price within the bookmakers covered by OddsWave, not every bookmaker in the market.

Both bookmaker prices and estimated probabilities can change. Either change can alter Value. A selection is removed on a successful refresh if it no longer meets the listing threshold, its valid data becomes unavailable or the match starts.

The page requests an update every 30 seconds. That interval is the page refresh schedule, not a guarantee that every bookmaker has supplied a new quote. If an update fails, the previous list may remain visible. Always confirm the available price at the bookmaker before using it.

These tools answer different questions:

• Value bets: Is a particular selection priced above its estimated fair odds? It can still lose.
• Sure bets: Can prices across all possible outcomes be combined to create a theoretical arbitrage profit? This depends on obtaining all required prices and matching settlement rules.
• Dropping odds: Which prices have fallen? A falling price does not, by itself, establish positive expected value.
