PlayDelta reads the gap between price and model.
The product is built for sports prediction-market research: source data, model fair line, delta gap, confidence, and risk state in one place.
Methodology reviewed July 11, 2026What PlayDelta is
An independent analytics interface that helps users understand where a sports market and a model read may disagree.
What PlayDelta is not
PlayDelta is not a sportsbook, exchange, broker, financial adviser, or betting-instruction service.
Five gates. No live price means no edge.
- 1. Verify the marketConfirm the matchup, start time, contract, and source. Fixture-only rows stay in Watch.
- 2. Read market priceLoad a current spread or implied probability. Missing or stale prices cannot produce a public edge.
- 3. Build model fairEstimate a fair line or fair probability from the available game and market context.
- 4. Measure deltaCompare model fair with market price. The named side shows which direction has more room.
- 5. Apply confidence and riskSource quality, agreement, timing, draw handling, and market movement determine Model Edge, Watch, or Risk-Off.
Points for lines. Percentage points for probabilities.
For spread markets, delta is the gap between the market line and PlayDelta fair line. For probability markets, delta is the gap between market-implied probability and model probability.
Confidence is read quality, not a promise.
A 75% confidence label does not mean a team has a 75% chance to win. It grades how complete and aligned the data is for that read.
Three outcomes must reconcile.
Regulation-time soccer markets are checked as home, draw, and away. If the draw contract is missing or the three-way probability book does not reconcile, PlayDelta suppresses the edge and shows Watch.
