Spread shows the home side at the consensus line with the best price among books quoting that line. Total shows the Over at the consensus number. Prediction market prices include trading fees, so they are directly comparable to sportsbook lines.
Baseball runs a full slate almost every day, and with so many games the price on a moneyline or run line can vary by 15 to 20 cents between books. The Odds Gap compares every MLB moneyline, run line, and total across the major US sportsbooks and the prediction exchanges so you can take the best number on the side you want.
The flag on each line marks the single best number available at the latest scan: the highest-paying moneyline on either side, the best juice at the 1.5-run line, and the best Over price at the consensus total. The free board scans hourly from 7am to 1am ET and Live Beta refreshes every minute, which matters in baseball because lineup cards and starting-pitcher news reprice games all afternoon.
The regular season runs from late March through September, followed by the postseason in October, and a typical day carries 12 to 15 games. That volume is the point: more games means more chances for one book to drift off the market, and the biggest per-game gaps on this site routinely come from the daily MLB slate.
Share of scanned MLB moneylines where each book posted the best available price, measured across the last 30 days. This is a track record, not a recommendation: the leader still loses the best price on most individual games, which is why the board above flags it per game.

| Caesars | 17.7% | 5,439 |
| Hard Rock Bet | 12.5% | 5,182 |
| ProphetX | 8.7% | 4,184 |

Hold is the margin built into a two-sided market: the two implied probabilities added together, minus 100. Lower is better for you. Across the 15 two-way MLB games priced right now:
That gap is the whole product. It is recomputed from the live board every scan, so it moves with the slate rather than being a claim we make once.
One email each morning with the biggest gaps on the board.

Every sportsbook sets its own prices. On the same MLB game, one book might post a side at -105 while another has it at -118. That difference is not noise: over a season of bets, taking the better number on every wager is often the difference between a winning and losing record. The Odds Gap scans 18 US sportsbooks plus Kalshi, Polymarket US, ProphetX and Novig every minute on the live board and flags where the best price sits on each line.
Each row is one upcoming MLB game. The moneyline columns show the single best price available on each side and which book has it. The spread column shows the home side at the market's consensus line, priced at the best odds among books quoting that line. The total shows the Over at the consensus number. For every book's price on every market, open the game in the Line Shop.
The moneyline is a bet on who wins, priced by how likely that is. The spread handicaps the favorite by points, so both sides pay close to even money. The total is a bet on the combined score going Over or Under a number. Whatever you bet, the only edge a recreational bettor reliably controls is the price, which is what this site exists to compare.
Every MLB game above has its own page with all of that on it, and it keeps the final score and closing odds after the game ends. All MLB game pages → or browse every league.
The best MLB price changes game to game, so rather than name one book, this page shows which sportsbook has the top number on each side right now.
The run line is baseball's spread, almost always set at 1.5 runs: the favorite must win by 2 or more, or the underdog must lose by 1 or win outright.
Yes. The Props page compares hits, total bases, home runs, RBIs, strikeouts, stolen bases, and the hits plus runs plus RBIs combo across books plus Kalshi, Polymarket US, ProphetX and Novig.
Every legal US sportsbook prices the daily MLB slate, but they disagree constantly. Filter this page to the books legal in your state and take whichever one holds the flag on your side.
Measured across the last 30 days, Novig posted the best MLB moneyline 64.8% of the time in our scans, ahead of Caesars 17.7%, Hard Rock Bet 12.5%, ProphetX 8.7%. That is a share, not a promise: no book leads every game, which is why this page flags the best price per game instead of naming one book to bet at.
On the 15 two-way MLB games on the board right now, the median hold at a single book is 4.2%. Taking the best price on each side, wherever it sits, cuts that to 0.4%: about 3.8 points of margin you keep by placing the same bet somewhere else. That figure moves with the slate and is recomputed every scan.
15, each with its own page showing every book's number on that game. The board above was last scanned September 9, 9:26 AM ET.
Each state page recomputes the best price across only the books you can legally bet there, plus the exchanges.
