What it does

The Odds Screen puts every book's price for a market on one row, one column per book. The best price for each side is tinted green and tagged BEST, and the Fair column shows the market's fair price with the vig removed, so you can see how far each book is from it.

Choose the league, the market (Moneyline, Spread, Total or Player props) and the date window from the top bar, then pick All books, My books or a single book with the gold Book: selector. A blank cell means that book has no price. Hover any price for its age and its EV against fair.

For player props, Open line ladder shows every main and alternate point for that player at every book, with a fair price at each point, including alt lines that only one book hangs.

Exchange and prediction-market cells show the net price after fees under the quote. A Kalshi contract at 50¢ is +100 on its face but −107 after the taker fee on a $100 order, and that net price is the one the screen uses to pick the best price.

Who it's for

  • Anyone who bets at more than one book and wants the best number before they bet.
  • Bettors in states without legal sportsbooks who use exchanges, prediction markets or sweepstakes books and need fee-adjusted prices.
  • Prop bettors who shop alternate lines, not just the main line.
  • Anyone learning how far apart books really are on the same market.

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.

GroupBooksHow we use them
Regulated US sportsbooksDraftKings, FanDuel, BetMGM, Caesars, Fanatics, theScore / ESPN BET, BetRivers, Hard Rock, Bally Bet, betPARXPriced and used in the market consensus. Not available in Georgia.
Usable from GeorgiaFliff and Rebet (sweepstakes), plus offshore booksSweepstakes books are priced like any book. Offshore books are shown for price comparison only: never linked or promoted.
Exchanges, prediction markets and sharp referencesKalshi, Polymarket, Novig, ProphetX, BetOpenly, Pinnacle, Betfair Exchange, Matchbook, Smarkets, MarathonbetExchanges 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 appsPrizePicks, Underdog, DK Pick6, DabbleLines 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.

Markets: moneylines (and 1X2 in soccer), spreads, totals, team totals, every alternate spread and total the books post, and player props with their alternates (passing, rushing and receiving yards, receptions, touchdowns; points, rebounds, assists, threes, PRA; shots, goals, saves; hits, total bases, strikeouts and more, by sport).

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

  • The price age on hover. A price that hasn't moved in a long time while the rest of the market has can be stale.
  • Whether the best price is an exchange quote. Exchange prices are finite offers: the size behind them can be small.
  • That the book's line is the same line you're comparing. An alt-line badge under a price means a different point.
  • Offshore columns are odds only. They're there for comparison, not as a recommendation.
  • The price at the book itself before you bet. Feeds can lag or be wrong.

How to use it

  1. Pick a league and a market in the top bar.
  2. Set the Book: selector to All books, My books or one book.
  3. Scan each row for the green BEST cell and compare it with the Fair column.
  4. On a prop, open the line ladder to compare every alternate point at every book.

Frequently asked questions

How is the fair price on the Odds Screen built?
Each book's two-sided price is devigged (probit by default), then the books are blended with the weights of your preset (All books by default). You can change the method and the weights in Fair value & filters; the settings apply to every tool.
Why is an exchange price different from what the exchange shows?
Exchanges and prediction markets charge fees that sportsbooks build into the price instead. We show and rank their prices at your net price after the venue's published fee schedule, so they're comparable with sportsbook odds.
Are pick'em apps on the Odds Screen?
Their lines are shown as lines, not prices. A pick'em leg's real price depends on the app's payout table and the entry you build, so it is never mixed into the odds math.
Does the Odds Screen show live odds?
No. The site is pregame only, and a game disappears at its start time.
Is it free?
During launch the market tools are free with a free account: sign in with Discord. The calculators and the Learning Center are always free and need no account.
Can I place a bet on The Sports King?
No. The Sports King is odds only and doesn't take bets. Prices are collected from public feeds for comparison and education; confirm the price at the book before you bet.
