Frequently Asked Questions

PropDolphin is a player prop research tool for sports bettors. We compare available sportsbook prices with a no-vig market reference and show hit-rate history, odds, and an estimated edge. Review the sample size and current price together before deciding whether a line fits your process.

No. PropDolphin is an informational research tool for entertainment purposes only. We don't accept wagers, facilitate betting, or hold funds. You place any wagers directly with your sportsbook; PropDolphin only provides research and comparison tools.

We compare each sportsbook's player prop line with a market reference, then remove the vig from the reference price to estimate a fair probability. The difference between that estimate and the offered price is the displayed edge. It is an estimate, not a prediction or guarantee. Each prop also shows its rolling hit-rate window (L5, L10, L15, or season) and the sportsbook price used in the comparison.

We currently cover MLB, WNBA, and NFL player props. We pull available lines from multiple U.S. sportsbooks so you can compare prices in one place. Coverage depends on the sport, market, and data available from each provider.

• Player prop tables that you can filter and sort across the sportsbooks in the feed

• Injury reports so you're not betting on a player who's inactive
