Sportsbook Props
Every player prop and alternate line at your books, priced against a fair line built without that book.
What it does
Sportsbook Props is the +EV screen set to player props. Every prop price at the books you pick is compared with a fair price built from the other books. The book you're betting is left out of its own fair price, and each row is ranked by expected value.
Each row shows the player and market, Your price at the selected book, the EV pill, To hit (the fair probability with fair odds under it) and an optional Kelly stake. Click a row for Why this is +EV: the books behind the fair price, the fair ladder and the written math.
A worked example: if the market's sharp two-way price on an over is −120 / +100, the probit fair for the +100 side is 47.7% (fair +110). A book hanging that side at +115 is +2.6% EV, and a quarter-Kelly stake is 0.57% of your bankroll.
Alt lines get a fair price too. The engine fits a fair ladder across every book's main and alternate points, so an alternate that only one book hangs still gets a fair value. Those rows are tagged MODELLED instead of EXACT LINE, and you should treat them with more caution.
Who it's for
- Prop bettors who want to know which props are priced off the market, not which players are "due".
- Bettors who bet at one or two books and want every prop at those books checked against the rest.
- Exchange and prediction-market users who need EV on the net price after fees.
- Anyone who sizes bets by edge (flat units or fractional Kelly).
Coverage
The collector is built for four groups of books. Which of them quote a given game depends on what each book posts, so a column can be empty.
| Group | Books | How we use them |
|---|---|---|
| Regulated US sportsbooks | DraftKings, FanDuel, BetMGM, Caesars, Fanatics, theScore / ESPN BET, BetRivers, Hard Rock, Bally Bet, betPARX | Priced and used in the market consensus. Not available in Georgia. |
| Usable from Georgia | Fliff and Rebet (sweepstakes), plus offshore books | Sweepstakes books are priced like any book. Offshore books are shown for price comparison only: never linked or promoted. |
| Exchanges, prediction markets and sharp references | Kalshi, Polymarket, Novig, ProphetX, BetOpenly, Pinnacle, Betfair Exchange, Matchbook, Smarkets, Marathonbet | Exchanges and prediction markets are shown at your net price after the venue's published fees. Pinnacle and the exchanges anchor the Sharp preset. |
| Pick'em apps | PrizePicks, Underdog, DK Pick6, Dabble | Lines only. A pick'em line is never treated as odds; its price comes from the app's payout table. |
Sports the collector is built for: NFL, college football, CFL, NBA, WNBA, college basketball, NHL, MLB, KBO, NPB and soccer (Premier League, MLS, La Liga, Bundesliga, Serie A, Ligue 1, Champions League). What you see on a given day depends on what is in season and what the books have posted.
Prop markets follow the sport: NFL and college football passing, rushing and receiving yards, receptions, completions, interceptions and anytime touchdowns; NBA, WNBA and college basketball points, rebounds, assists, threes and PRA; NHL points, goals, assists, shots on goal, saves and power-play points; MLB hits, total bases, home runs, RBIs, runs, walks and pitcher strikeouts, outs and earned runs; soccer anytime scorer, shots and shots on target. Alternates are included wherever the books post them.
Pregame only. There are no live odds anywhere on the site, and a game drops off every tool at its start time. Refresh speeds up near the start: game lines every minute inside 2 hours, every 5 minutes from 2 to 12 hours, every 15 minutes from 12 to 36 hours and every 3 hours beyond; props every 5, 15 and 60 minutes in the first three windows. A credit budget guard slows the far windows first if credits run low. The ● Live · 12s badge in the top bar shows the true age of the newest collector run and turns amber (Delayed) when it is older than it should be.
What to check before you bet
- EXACT LINE or MODELLED. An exact-line fair is built from the books' own two-way prices at that point; a modelled fair comes from the ladder.
- How many books back the fair (Books at line). The default minimum is 3.
- Longshots. They lead on raw EV% and carry the most model risk. The default odds cap is +400.
- Price age, and whether the book still offers it. Props move fast and books limit winning prop bettors.
- THIN exchange markets: wide two-sided spreads are shown but never used to build a fair price.
