The 2026 World Series winner market is the deepest futures board in baseball, trading across roughly $60.8M in cumulative volume with all 30 clubs priced on both Kalshi and Polymarket. The Los Angeles Dodgers anchor the favorite tier, with the New York Yankees the clearest second and a broad pack of National League and American League contenders behind them. The live board above ranks the current cross-platform prices on every team; the market resolves when the World Series ends, with a deadline of October 31, 2026.
The 2026 World Series winner market is the single largest baseball futures board on the prediction-market calendar, with all 30 MLB clubs listed on both Kalshi and Polymarket and roughly $60.8M in cumulative volume across the field. The shape of the board is durable even as individual prices move: a thin favorite tier led by the Los Angeles Dodgers, a clear second tier built around the New York Yankees and the league's other heavyweight rosters, and a long tail of low-single-digit clubs that need a deadline upgrade or a healthy October to matter. The live board above always shows the current cross-platform cents on every team.
The Dodgers sit at the top of the field for structural reasons that outlast any one week of trading: the deepest payroll in the sport, a rotation built to survive a long postseason, and a lineup that has carried the highest preseason and in-season win-total projections in baseball. As the defending-era benchmark for the National League, Los Angeles is the team the rest of the board is priced against, which is why their number tends to move first when a contender stumbles.
The New York Yankees are the most stable second name. A right-handed power core, a deep American League East, and the largest postseason-revenue incentive in the game keep New York in the conversation regardless of midseason variance. When the Yankees' price firms, it usually comes at the expense of the rest of the AL field rather than the Dodgers.
Behind the top two, the contender pack is genuinely flat and is where most of the trading action concentrates. The Milwaukee Brewers and Atlanta Braves headline the next tier on the strength of run prevention and roster continuity, while the Seattle Mariners and Philadelphia Phillies round out the group of clubs the market treats as live World Series threats rather than longshots. This middle band is the most price-sensitive part of the board: a single series win streak, a trade-deadline addition, or a rotation injury can swing these names by several cents in a day, which is exactly what the live board above is built to capture.
The long tail spans most of the remaining clubs, from established playoff regulars like the Toronto Blue Jays, Tampa Bay Rays, Chicago Cubs, San Diego Padres, and Houston Astros down to rebuilding rosters priced near the floor. For these teams the market is effectively pricing the probability of a deadline upgrade plus a hot October, not a season-long favorite's path. The MLB pennant and division markets feed directly into this board, since a club has to win its league before it can win the title.
The market resolves to the team that wins the 2026 World Series, the best-of-seven championship series between the American League and National League pennant winners, played in late October 2026. The board carries a resolution deadline of October 31, 2026. Each team contract pays out if that club wins the title; every other team contract resolves to zero. If the World Series is canceled or cannot be completed by the resolution date, the market settles under each platform's published void rules.
This board is the headline of the baseball futures slate. Pair it with the American League pennant market and the National League pennant market to see each league's path to the title, and browse the full MLB markets hub for team win totals, division races, and daily game lines.
