MLB Odds Across Every Prediction Market
World Series futures, pennant and division races, win totals and game markets - live prices side by side from every platform quoting them.
Understanding MLB Odds on Prediction Markets
MLB odds on a prediction market are not lines set by a bookmaker - they are the last traded price of a contract, set by whoever is willing to buy and sell it. Every outcome on this page trades as its own contract that pays $1.00 if it happens and nothing if it does not, quoted in cents in between. That makes the price and the probability the same number: a team at 15¢ is the market saying 15%, with no vig to strip out first. When you compare that against a sportsbook's +567 on the same team, you are comparing a clean probability against one with margin folded in.
This page covers every matched MLB market we track: the World Series champion, AL and NL pennants, all six division races, regular-season win totals, the award markets - MVP, Cy Young and Rookie of the Year in both leagues - and the daily game moneylines as each slate posts. Each card shows every platform currently quoting that market side by side.
Two venues carry most of the baseball volume, and they rarely agree exactly. Kalshi is a CFTC-regulated US exchange trading in USD; Polymarket settles in USDC, draws global participation, and usually carries the largest size on the marquee markets. A two-to-four cent spread between them on the same team is routine; a wider one on a liquid market means the cheaper side is the better entry for an identical payoff.
How to Read the Odds Cards Above
Each card is one event. The platform cells carry the live price at every venue quoting each outcome, and the cheapest quote is highlighted - it is the best available buy for an identical payoff. Prices link out to the market on the platform itself, and the card opens the full cross-platform table with price history, so a disagreement between venues is always one tap from the trade.
Cents, Implied Probability and American Odds
The same MLB price can be written three ways. Contracts quote cents, forecasters use percentages, and sportsbooks use American odds - all describing one number.
| Price | Implied | American | What it means |
|---|---|---|---|
| 3¢ | 3% | +3233 | Longshot - half the league prices here by August |
| 8¢ | 8% | +1150 | Fringe contender with a live playoff path |
| 15¢ | 15% | +567 | Typical World Series favorite mid-season |
| 30¢ | 30% | +233 | Strong pennant favorite |
| 50¢ | 50% | +100 | Coin flip - a tight division race in September |
| 80¢ | 80% | -400 | Near-lock; the market has mostly moved on |

Why Baseball Futures Trade Differently
A 162-game season makes baseball futures the most information-rich markets in sports: prices grind on evidence rather than jumping on single results. The moves that matter rarely come from one game - an ace's elbow, a trade-deadline rental, a September collapse in the bullpen each reprice a race because they change every remaining game at once. And October flattens everything: the playoff format keeps even a 100-win team's World Series price modest, which is why baseball favorites always look cheap next to favorites in other sports.
The award races are the swing markets. MVP, Cy Young and Rookie of the Year price a ballot rather than an outcome, so narrative and playing time move them as much as production - a two-week hot streak or an innings-limit rumor can reprice a Cy Young race faster than a month of quality starts. Watching where the award money disagrees with the stat lines is one of the sharper reads this page offers.
MLB Markets Covered on This Page
Every family below is priced across all quoting platforms in the grid above.
World Series Champion
The marquee baseball future: every club priced to win the 2026 World Series, quoted side by side across platforms. Baseball’s long playoff gauntlet keeps even heavy regular-season favorites cheaper than favorites in other sports - the best team in baseball rarely clears 25% in October.
AL & NL Pennants
Odds to win the American League and National League pennants. Comparing a team’s pennant price against its World Series price tells you how the market rates it in a short series once it gets there.
Division Winners
All six division races. A 162-game schedule makes these the most information-rich futures in sports - prices grind rather than jump, and a September series between rivals can swing a race by ten points in a weekend.
Win Totals (Over/Under)
Season win totals per club, traded as over/under contracts. The cleanest way to disagree with the market about a team without picking an October outcome.
Awards: MVP, Cy Young, Rookie of the Year
MVP and Cy Young in both leagues plus Rookie of the Year. Award markets price a vote, not a stat line - narrative, playing time and team success move them as much as production does.
Game Markets
Daily moneylines as each slate posts. Baseball’s day-in, day-out schedule means these turn over faster than any other sport we track.

How This Page Works
Prices come from each platform's own API and refresh at least once a minute. Contracts are quoted in cents and shown as implied probabilities, so a 15¢ price reads as 15%. Only markets matched across platforms appear here, and a market drops off the page when no platform is quoting it - an empty topic means no live market rather than an error. Market availability and legality vary by platform and by state. This page is informational and is not betting or investment advice.
