MLB Playoffs Odds 2026: The Model's Full Postseason Bracket
Kalshi has turned the entire 2026 MLB postseason into a wall of yes/no contracts: one World Series champion market, an American League and a National League pennant market, and six separate division-winner races. This page pulls all of it into a single bracket and runs every board through the same test. We asked a panel of AI models to price each race without letting any of them see a single Kalshi quote, then set their numbers next to the real money. The through-line, on every board, is the same argument: the market is paying a premium for the Los Angeles Dodgers that the models will not match.
The Quick Answer
As of August 7, 2026, Kalshi's World Series board makes the Dodgers a runaway favorite near 36 cents, more than three times the price of any other team. The AI panel, pricing blind off current records and run differential, puts the Dodgers around 11 percent and ranks them third, behind Milwaukee (the best record in baseball at 72-43) and Atlanta. The panel's read is not that Los Angeles is bad. It is that October is a short-series lottery, three National League clubs are effectively tied at the top, and no single team deserves a 36 percent crown this far out. The full model-by-model World Series board, both pennant races, all six division brackets, and the spots where the panel disagrees hardest with the market are below.

How To Read This Bracket
Every price on this page is a Kalshi cent quote, fetched August 7, 2026. A contract trading at 36 cents implies roughly a 36 percent chance, and it pays out at one dollar if it resolves yes. Each Kalshi market settles yes for exactly one outcome: the World Series market on the champion, each pennant market on the club that wins its league, each division market on the club that finishes first in that division.
The "AI blend" column is the equal-weight average of the panel's estimates. Each model received the same fetched card (current division standings and run differential from MLB's StatsAPI, pulled the day it was scored) and none of them saw a market price. On the World Series and both pennant boards the panel also ran a revision round, where each model read the others' anonymized reasoning and could adjust. The "gap" is simply blend minus market: a positive gap means the panel likes a team more than Kalshi does, a negative gap means it likes them less. Run differential (RD) is runs scored minus runs allowed, the single best "true talent" proxy this early, and it is the number the models leaned on most.
These are model estimates, not predictions of fact and not financial advice. Kalshi is a CFTC-regulated event-contract exchange, availability varies by state, and its markets are 18+.
The World Series Board
This is the headline race, freshly scored on August 7, 2026. Thirty teams, one champion, and the widest market-versus-model gap of the entire postseason sits right at the top.
The market's logic is pedigree: the Dodgers carry the deepest roster and the October track record, so the money concentrates on them. The panel's logic is arithmetic: Milwaukee owns the best record and run differential in the sport, Atlanta is right behind and red-hot, the Dodgers are a close third who happen to have lost six in a row into the fetch, and a short October series caps how confident anyone can be. No model priced a single team above 13.3 percent.

| San Diego Padres | 4.0 | 3.0 | 3.0 | 3.0 | 3.2 | 3.2% | 1.4c |
Note how tight the five seats are on the top of this board. That agreement is the point: the panel is not one contrarian model dragging a number down. Every seat, independently and then again after reading the others, landed Milwaukee first and the Dodgers third.
More live boards from the same panel: World Series champion, the standalone board (Dodgers 36c, panel 11%) · AL pennant race (Yankees 22c, a true toss-up) · NL West, is it already over? (Dodgers 97c). Prices fetched August 7, 2026.
The Biggest Gap: The Dodgers Premium
One team drives the story of this entire bracket. Kalshi prices the Dodgers at 36 cents to win the World Series, 47 cents to win the National League, and 97 cents just to win the NL West. The panel says 11 percent, 24 percent, and 92 percent for the same three questions. The division number is close. The championship numbers are a chasm.
Here is the honest version of why the two disagree. The models were handed records and run differential, and on those inputs Los Angeles is excellent but not singular: their +140 run differential is a hair behind Milwaukee's +141 and ahead of Atlanta's +121, a three-way photo finish, not a coronation. They were also carrying a six-game losing streak on the day the panel scored the World Series board, which GLM flagged directly. The market is pricing something the card did not contain: bullpen depth, a healthy rotation for October, and a roster built for a series rather than a marathon. That is a real input, and it is fair for the market to weight it.
So read the gap as a question, not a verdict. If you believe an elite roster's October ceiling is worth paying up for, the Dodgers at 36 cents look right and the panel is too flat. If you believe run differential and records are the honest guide this far out, three NL clubs are nearly interchangeable and 36 cents is too rich for one of them. The panel is firmly in the second camp.
The Pennant Races
A pennant market asks which club wins its league and reaches the World Series. Here the two leagues could not look more different.
American League pennant (8-model panel, sorted by Kalshi price):
| Team | Rec (RD) | Kalshi | AI blend | Gap |
|---|---|---|---|---|
| New York Yankees | 64-51 (+81) | 21.5c | 23.2% | +1.7 |
| Boston Red Sox | 63-51 (+77) | 20.5c | 12.6% | -7.9 |
| Tampa Bay Rays | 68-46 (+41) | 18.5c | 18.3% | -0.2 |
| Houston Astros | 59-57 (-25) | 9.5c | 4.9% | -4.6 |
| Chicago White Sox | 59-55 (+38) | 8.5c | 14.1% | +5.6 |
| Seattle Mariners | 56-60 (-14) | 6.5c | 4.9% | -1.6 |
| Cleveland Guardians | 57-59 (-28) | 4.5c | 3.9% | -0.6 |
| Texas Rangers | 57-58 (-33) | 3.5c | 5.5% | +2.0 |
| Detroit Tigers | 56-59 (+80) | 2.5c | 5.4% | +2.9 |
| Minnesota Twins | 57-59 (-35) | 1.5c | 4.9% | +3.4 |
The AL is a scrum. The panel agrees with the market that the Yankees are the marginal favorite (their +81 run differential is the league's best), but it splits from Kalshi on the shape underneath. It fades Boston hard, from 20.5 cents to 12.6 percent, reading the Red Sox as a good team the market has overpriced into the top tier. And it lifts the White Sox from 8.5 cents to 14.1 percent, the largest positive gap on the AL board, a lean on run differential over reputation.
National League pennant (5-model panel, sorted by Kalshi price):
| Team | Rec (RD) | Kalshi | AI blend | Gap |
|---|---|---|---|---|
| Los Angeles Dodgers | 69-46 (+140) | 47.5c | 24.2% | -23.3 |
| Milwaukee Brewers | 72-43 (+141) | 18.5c | 22.2% | +3.7 |
| Atlanta Braves | 70-45 (+121) | 12.5c | 17.0% | +4.5 |
| Chicago Cubs | 67-49 (+100) | 11.5c | 11.2% | -0.3 |
| Philadelphia Phillies | 62-54 (+2) | 9.5c | 7.2% | -2.3 |
| Arizona Diamondbacks | 61-55 (+3) | 2.5c | 5.0% | +2.5 |
| San Diego Padres | 60-56 (-13) | 2.5c | 3.6% | +1.1 |
The NL is the mirror image of the AL. Kalshi has one clear favorite, the Dodgers at 47.5 cents. The panel refuses the coronation and instead prices three near-equal giants: Dodgers 24 percent, Brewers 22 percent, Braves 17 percent. As Kimi put it in the revision round, "the NL has three near-equal giants, not one," pointing at the run-differential cluster (Milwaukee +141, Los Angeles +140, Atlanta +121) as statistically indistinguishable. If the panel is right, the model's edge on this board is on Milwaukee and Atlanta, not the favorite.
The Division Bracket
Division markets settle first, at the end of the regular season, so they carry the least October variance and the tightest agreement between panel and market. Four of the six are close. Two hold a real edge.
AL East — a three-team fight the panel and market both read the same way, with the Rays holding on.
| Team | Rec (RD) | Kalshi | AI blend |
|---|---|---|---|
| Tampa Bay Rays | 68-46 (+41) | 53.0c | 58.5% |
| New York Yankees | 64-51 (+81) | 23.5c | 21.3% |
| Boston Red Sox | 63-51 (+77) | 20.5c | 17.1% |
AL Central — the board with the sharpest division-level disagreement. The market backs Cleveland as the main threat to the White Sox; the panel backs Detroit instead, and by a lot.
| Team | Rec (RD) | Kalshi | AI blend | Gap |
|---|---|---|---|---|
| Chicago White Sox | 59-55 (+38) | 51.0c | 45.8% | -5.2 |
| Cleveland Guardians | 57-59 (-28) | 26.5c | 15.3% | -11.2 |
| Detroit Tigers | 56-59 (+80) | 16.0c | 26.0% | +10.0 |
| Minnesota Twins | 57-59 (-35) | 10.0c | 10.0% | 0.0 |
Detroit is the cleanest run-differential story in the sport: a 56-59 record that looks mediocre sitting on a +80 run differential that says the Tigers have been dramatically unlucky. The panel treats that as coiled positive regression and prices Detroit at 26 percent to steal the division while the market has them third-priced at 16 cents. Cleveland is the inverse, a 26.5-cent price sitting on a negative-28 run differential the models simply do not trust.
AL West — the market leans Houston; the panel sees a true three-way race and keeps Houston only narrowly ahead.
| Team | Rec (RD) | Kalshi | AI blend |
|---|---|---|---|
| Houston Astros | 59-57 (-25) | 46.5c | 37.4% |
| Seattle Mariners | 56-60 (-14) | 29.0c | 32.6% |
| Texas Rangers | 57-58 (-33) | 25.0c | 26.6% |
All three AL West contenders are running negative run differentials, which is why the panel refuses to give the leader a big number: Houston stays the panel's top pick at 37.4 percent on the strength of its standings lead, but its negative-25 differential is worse than Seattle's negative-14, so the models compress the Mariners (32.6 percent) and Rangers (26.6 percent) right up against the Astros into a near coin-flip.
NL East — the least interesting board in the bracket, and that is a compliment to Atlanta.
| Team | Rec (RD) | Kalshi | AI blend |
|---|---|---|---|
| Atlanta Braves | 70-45 (+121) | 86.5c | 91.2% |
| Philadelphia Phillies | 62-54 (+2) | 10.0c | 5.0% |
The Braves lead by 8.5 games with the best run differential in the division, and the panel is even more confident than the market, pushing them past 91 percent and fading Philadelphia's flat +2 differential.
NL Central — Milwaukee is near-certain; the only question is how much of the leftover the Cubs deserve.
| Team | Rec (RD) | Kalshi | AI blend |
|---|---|---|---|
| Milwaukee Brewers | 72-43 (+141) | 76.5c | 82.5% |
| Chicago Cubs | 67-49 (+100) | 24.5c | 14.8% |
Milwaukee has the best record in baseball and a 5.5-game cushion, so the panel prices them higher than the market at 82.5 percent and fades the Cubs, whose 24.5-cent price implies more comeback than a +100 run differential five-plus games back can support.
NL West — effectively decided. The Dodgers hold a division-winner grip the panel shaves only slightly.
| Team | Rec (RD) | Kalshi | AI blend |
|---|---|---|---|
| Los Angeles Dodgers | 69-46 (+140) | 97.5c | 91.6% |
| Arizona Diamondbacks | 61-55 (+3) | 1.0c | 5.2% |
| San Diego Padres | 60-56 (-13) | 1.0c | 2.4% |
This is the one Dodgers market the panel mostly agrees with. At 97.5 cents the division is priced as a near-certainty, and the models concur at 91.6 percent while carving out a small Arizona tail the market has rounded to zero.
Dark Horses The Panel Won't Dismiss
The top of every board gets the attention. These are the cheap contracts where at least one model saw a real number the market did not.
- Detroit Tigers. The +80 run differential on a losing record is the loudest regression signal in the league. The panel prices Detroit at 26 percent in the AL Central (market 16 cents) and lifts them on the pennant board too. If the Tigers' record catches up to their run prevention, this is the largest positive gap on the AL board.
- Arizona Diamondbacks. A +3 run differential and a 61-55 record buried at 0.9 cents in the World Series market. The models give them 3.5 percent to win it all, nearly four times the price, and 5 percent in the NL West where the market sees only the Dodgers.
- San Diego Padres. Priced as an afterthought at 1.4 cents in the World Series market, the panel has them at 3.2 percent. Not a favorite, but a live October team the money has written off entirely.
- Chicago White Sox. The AL Central leader the pennant market underrates. Kalshi has them fifth on the AL pennant board at 8.5 cents; the panel, trusting the +38 run differential behind the division lead, prices them at 14.1 percent.
Where The Panel Changed Its Mind
On the World Series and pennant boards, each model read the others' anonymized reasoning and could revise. The movement was small but pointed, and it tightened the top.
On the NL pennant board, GLM made the clearest revision: "I revised upward on Milwaukee from 18 to 23 after peers correctly flagged that I had underweighted the Brewers' league-best record and near-identical bye positioning relative to the Dodgers." That is one model conceding the exact point that separates the panel from the market, that Milwaukee belongs level with Los Angeles, not a tier below.
On the World Series board, Opus moved the other direction on the American League, choosing to "cap Rays since the AL's best is weaker than three NL clubs," a bet that the National League simply has more championship-caliber teams this year. And one seat held its ground on purpose: Sonnet reported it "held near-original," because its win-percentage ladder (Brewers, then Braves, Dodgers, Rays, and Cubs) "already matched consensus," and it nudged only Tampa Bay and the Cubs up toward the group. When a model tells you it read the four other analyses and saw no reason to move, that is a signal too.
What Would Change The Panel's Mind
This board is a snapshot of early August. Here is what would move the numbers, and which direction each push goes.
- The Dodgers End Their Skid And Separate. If Los Angeles turns its six-game slide into a September surge and pulls clear of Milwaukee and Atlanta on run differential, the panel's fade closes and the market's 36-cent price starts to look right rather than rich. Pushes the Dodgers up.
- Detroit's Record Catches Its Run Differential. A Tigers hot streak that converts +80 into an actual division lead would validate the panel's biggest division-level call and crater Cleveland's price. Pushes Detroit up, Cleveland down.
- A September Injury To A Rotation Anchor. The card cannot see health. A staff ace landing on the injured list for any contender is the input most likely to break the panel away from the market in a hurry. Pushes the affected team down.
- The Wild-Card Picture Hardens. Several of these teams (the Astros, Mariners, and Rangers in the AL West especially) are separated by a game or two. Once the division and wild-card slots lock in late September, the division markets converge fast toward 100 or zero, and the pennant boards reprice around who actually drew a bye.

Frequently Asked Questions
Who is the favorite to win the 2026 World Series? On Kalshi, the Los Angeles Dodgers are the runaway favorite at about 36 cents as of August 7, 2026, more than three times the next team. Our price-blind AI panel disagrees and ranks the Milwaukee Brewers first at roughly 13 percent, since Milwaukee owns the best record and run differential in baseball at 72-43. The panel puts the Dodgers third at about 11 percent, behind Milwaukee and Atlanta.
When does the 2026 MLB postseason start and when do these markets settle? The six division-winner markets settle at the end of the regular season in late September 2026. The postseason itself begins in early October with the Wild Card round, the League Championship Series decide each pennant market in mid-to-late October, and the World Series market settles on the champion in late October 2026 (Kalshi lists an expected expiration of November 1, 2026).
Which team does the model disagree with the market on most? The Los Angeles Dodgers, on every board. Kalshi prices them at 36 cents to win the World Series and 47 cents to win the National League; the panel says about 11 percent and 24 percent. The panel, working from records and run differential, sees three near-equal NL clubs (the Dodgers, Brewers, and Braves) rather than one dominant favorite, so it treats the market's Dodgers premium as too rich this far out.
Which cheap teams does the AI panel like more than Kalshi does? The clearest value is the Detroit Tigers, whose 56-59 record hides a plus-80 run differential that signals strong positive regression; the panel prices them at 26 percent to win the AL Central versus the market's 16 cents. It also likes the Arizona Diamondbacks and San Diego Padres as deep World Series longshots, and the Chicago White Sox on the AL pennant board.
Do the AI models see the Kalshi prices before scoring? No. Every model is scored price-blind: it receives only a fetched card of current standings and run differential and never sees a market quote. The World Series and pennant boards also run a revision round where each model reads the others' anonymized reasoning and can adjust. These are model estimates, not predictions of fact and not financial advice.
Methodology, In Plain Terms
Eight AI models make up the full panel: three Claude models (Opus, Sonnet, and Fable), the GLM, Kimi, and DeepSeek models, and a GPT and a Gemini seat when their tools are available. Each board here reflects the seats that returned a valid, price-blind distribution on the day it ran (five on the freshly scored World Series board, five on the NL pennant, eight on the AL pennant, six on each division board); seats that were unavailable are simply left out rather than guessed. Every model was shown the same fetched card of current standings and run differential and none of them saw a Kalshi price. The World Series and pennant boards also ran a revision round. Every estimate is stored and graded once the market settles, and the running record lives on the full graded scoreboard. Every number in this piece gets graded in public when the season ends.
To be explicit: these are model estimates, not predictions of fact and not financial advice. Kalshi is a CFTC-regulated event-contract exchange, its markets are 18+, availability varies by state, and prices move. Nothing here is a recommendation to trade.
