2026 World Series Predictions: Final Four Odds and Schedule

The confirmed 2026 postseason calendar, a timestamped October 11 championship board from the exact Polymarket event with four teams left, Division Series results, resolution rules, and research checkpoints through the World Series.

Published July 30, 2026 · Refreshed October 11, 2026 · Wild Card Series: September 29–October 1 (completed) · Division Series: October 3–10 (completed) · Championship Series: October 11–20 · World Series Game 1: October 23 · Next planned refresh: October 21

The answer first

The 2026 World Series begins Friday, October 23, with a potential Game 7 on Saturday, October 31. The Wild Card Series ran September 29–October 1 and the Division Series October 3–10; the League Championship Series begin Sunday, October 11, with the Dodgers at the Brewers in the NLCS, followed by the Guardians at the Rays in the ALCS from October 12. Four teams remain: the Dodgers, Brewers, Rays and Guardians. On the exact Polymarket event MLB World Series Champion 2026, checked at about 14:02 UTC on October 11, the Los Angeles Dodgers led at 42.5%, followed by the Milwaukee Brewers at 25.8%, Tampa Bay Rays at 22.6%, and Cleveland Guardians at 9.6%. Four named teams were still open, 26 team contracts had closed, and the event showed about $44.02 million in cumulative volume. It resolves to the team that wins the World Series—not the regular-season leader, a division winner, or a pennant winner.

October 11 snapshot: the championship board at the final-four gate

Displayed YES prices from the public Gamma snapshot at about 14:02 UTC on October 11, 2026, the day the Championship Series begin, after all four Division Series ended. They are last recorded outcome prices, not executable quotes; bid/ask are the recorded book edges, and the volume column is each team contract's lifetime volume.

TeamDisplayed YESBid / AskContract volume
Los Angeles Dodgers42.5%42 / 43$836,019
Milwaukee Brewers25.8%25.2 / 26.4$1,830,631
Tampa Bay Rays22.6%22.3 / 22.9$723,645
Cleveland Guardians9.6%9.4 / 9.8$1,348,987

These four rows are every named team still open; the other 26 team contracts have closed as their teams were eliminated. The board has tightened round by round: on September 23 the Dodgers led a 17-team field at 30.5%, and on October 3, with eight teams left, they still stood at 30.5%. The Division Series then re-priced the field: the Dodgers (30.5% → 42.5%) and Brewers (17.05% → 25.8%) gained most, while the eliminated Yankees (13.5%) and Padres (10.95%) rows closed. The four displayed prices sum to about 100.5%, a small over-round typical of multi-outcome books. An unpriced Will another team fallback row completes the open inventory.

How to read this board: even the 42.5% favorite is more likely than not to lose somewhere across the two remaining rounds. Lifetime volume and current likelihood are still different things: the Guardians carry more lifetime volume ($1,348,987) than the Rays ($723,645) while trading at 9.6% versus 22.6%.

The official 2026 postseason calendar

September 27 · Regular season ends

MLB's 2026 schedule announcement lists Sunday, September 27 as the final regular-season day, with 15 games on the official slate.

September 29–October 1 · Wild Card Series

All four best-of-three Wild Card Series open Tuesday, September 29; Game 2 is September 30 and any Game 3 is Thursday, October 1.

October 3–10 · Division Series (completed)

The Guardians beat the White Sox 3–2, the Rays swept the Yankees, and the Dodgers and Brewers each advanced 3–1 over the Braves and Padres. Full scores in the section below.

October 11–20 · League Championship Series

The NLCS opens October 11 with the Dodgers at the Brewers (Games 1–2 and any 6–7 in Milwaukee, 3–5 in Los Angeles); the ALCS opens October 12 with the Guardians at the Rays (Games 1–2 and any 6–7 in Tampa Bay, 3–5 in Cleveland). Potential Game 7s: NLCS October 19, ALCS October 20.

October 23 · World Series Game 1

The World Series opens Friday, October 23 at the National League champion's park: Games 1–2 and any 6–7 belong to the NL side, Games 3–5 to the AL side, with a potential deciding Game 7 on Saturday, October 31, the same date as the prediction event's top-level end field.

December 31 is an edge-case deadline

The event's written rules use December 31, 2026 Eastern Time for cancellation, postponement, or no-winner fallback handling. That exceptional deadline is separate from the postseason calendar.

Calendar discipline: postseason dates come from MLB's published schedule as reported by CBS Sports and MLB.com; game times and TV windows are set separately. The prediction event's October 31 end field matches a possible Game 7 but does not by itself settle the market.

How the Division Series settled (October 3–10)

Rays 3, Yankees 0

Tampa Bay swept New York: 1–0 at home on October 3, 5–2 at home on October 5, and 4–3 in New York on October 7. The Yankees' championship contract closed on elimination.

Guardians 3, White Sox 2

Cleveland lost the first two games at home (0–3, 3–4), then took three straight: 9–3 and 9–5 in Chicago and a 2–0 clincher at home on October 10 — the only Division Series to go the distance.

Dodgers 3, Braves 1

Los Angeles won 5–3 at home, dropped a 3–2 game, then closed the series with 3–1 and 4–1 wins in Atlanta on October 6–7.

Brewers 3, Padres 1

Milwaukee took both home games (3–2, 4–3), dropped a 4–3 game in San Diego, and clinched 3–1 on the road on October 7.

Results are elimination facts: under the event's written rules, each Division Series loser's team contract resolves No because winning the World Series became impossible. A survivor's price, by contrast, still prices uncertainty across two more rounds.

2026 World Series research timeline

July 30 · Durable baseline
The official MLB schedule announcement, final-day Stats API slate, official postseason-window API query, exact Gamma event, public Polymarket page, every local event hub, complete blog archive, sitemap, proactive queue, today's publisher state, and latest local GSC reports were checked. No team price was preserved.
Late August through September · Playoff-race wave
As division and Wild Card races narrow, search intent should move from broad season forecasts toward qualification paths, remaining schedules, tiebreak questions, and individual team championship scenarios. A model projection or market price still does not prove qualification.
September 23 · Pre-postseason refresh
The published postseason calendar was added and the championship board recorded: Dodgers 30.5%, Brewers 16.55%, Rays 10.9%, Yankees 8.5%; 17 named teams open, 13 closed; about $41.04M cumulative volume.
September 27 · Regular-season finale
MLB's official schedule lists 15 games on the final day. Division titles, Wild Card berths, or seeding questions may become final around this window, but a postseason berth is not a World Series victory.
September 29–October 1 · Wild Card Series (completed)
Four best-of-three series, settled on the field: the Yankees swept the Red Sox, the White Sox swept the Astros, the Padres swept the Cubs, and the Braves beat the Phillies 2–1. Losing teams became unable to win the World Series, and their contracts closed to No under the elimination rule.
October 3 · Post-Wild-Card refresh
The board was re-recorded the day both Division Series open: Dodgers 30.5%, Brewers 17.05%, Yankees 13.5%, Padres 10.95%, Rays 10.65%, Braves 8.55%, Guardians 6.9%, White Sox 4.2%; eight named teams open, 22 closed; about $42.95M cumulative volume.
October 3–10 · Division Series (completed)
The Rays swept the Yankees, the Guardians came back from 0–2 down to beat the White Sox 3–2, and the Dodgers and Brewers each advanced 3–1, over the Braves and Padres respectively; the field narrowed to four teams and 26 team contracts closed.
October 11 · LCS-start refresh (this update)
The board was re-recorded the day the Championship Series begin: Dodgers 42.5%, Brewers 25.8%, Rays 22.6%, Guardians 9.6%; four named teams open, 26 closed; about $44.02M cumulative volume. The NLCS opens today in Milwaukee; the ALCS follows October 12 in Tampa Bay.
October 12–20 · League Championship Series
The NLCS (Dodgers–Brewers) and ALCS (Guardians–Rays) decide the two World Series participants; potential Game 7s fall on October 19 and October 20.
October 23 · World Series Game 1
The championship series opens; only two team contracts can still resolve Yes.
October 31 · Potential Game 7 and event end date
A deciding Game 7 would fall on this date, which the reviewed event metadata also carries as its end field. Researchers should not assume a countdown alone resolves the market: the winner and exceptional fallback are defined in the event description.
December 31 · Written exceptional boundary
If the season is cancelled, postponed beyond this date in Eastern Time, or no World Series winner is declared by then, the reviewed rules assign the event to Other. Preserve the current wording before evaluating any extraordinary delay.

What the verified World Series prediction event contains

The public event was first checked at approximately 14:05 UTC on July 30, rechecked at about 13:00 UTC on September 23, and again at about 16:39 UTC on October 3, after the Wild Card Series. Counts below separate named teams from the special fallback row and describe API state at one timestamp rather than promising that every field will stay unchanged.

One exact championship event

The top-level event is titled MLB World Series Champion 2026, uses slug mlb-world-series-champion-2026, was active and not closed, and displayed all 30 MLB clubs as named outcomes.

4 named teams still open

On July 30 all 30 named-team rows were active and accepting orders. By September 23, 17 remained open; after the Wild Card Series, eight; after the Division Series, the October 11 check shows four named teams still open (Dodgers, Brewers, Rays, Guardians) and 26 team contracts closed. Each is a separate YES/NO contract, not an official MLB forecast.

One separate Other row

The event metadata also retained an Other fallback row. It was marked inactive while its accepting-orders field was still true, an inconsistency that reinforces why status flags and resolution text must be reviewed together.

Timestamped event scale

Top-level metadata reported about $44.02 million in cumulative volume, $175,000 in 24-hour volume, and $0.6 million in liquidity on October 11 (October 3: $42.95 million, $233,000 and $0.86 million; September 23: $41.04 million, $71,900 and $2.05 million; July 30: $36.93 million and $4.61 million). Those fields are a dated event-level snapshot, not a guarantee of executable depth in any team contract.

Prices are timestamped

The October 3 board above is a dated record. A last trade can move before Google recrawls this page and can differ from the current bid, ask, or available size; use the live event for present quotes.

Status is not settlement

Active, closed, accepting-orders, and end-date fields describe platform state. None by itself proves that a team has won, been eliminated, or met the written resolution condition.

Why the board appears now: in July this page deliberately published no prices months before the postseason. With the field cut to four and the Championship Series starting, a dated snapshot is useful context, as long as it is read as history rather than a live quote.

How the 2026 World Series market resolves

1. World Series champion only

The reviewed event selects the team that wins the 2026 MLB World Series. Best regular-season record, division title, Wild Card berth, American League pennant, or National League pennant is not the same outcome.

2. Official MLB source first

The description names official Major League Baseball information as the primary resolution source. It also allows a consensus of credible reporting, but a prediction model, betting screen, fan post, or market price is not the named primary evidence.

3. Impossibility can settle No

The reviewed rule says a listed team resolves No when it becomes impossible for that team to win under MLB rules, including playoff elimination. Being far behind, having a difficult schedule, or receiving a low price is not itself elimination.

4. Qualification is not victory

A team can clinch a postseason berth or win its division while still needing to advance through later rounds. Preserve the specific team question and do not substitute a different MLB market's result.

5. Other covers exceptional failure

If the season is cancelled, postponed beyond December 31, or produces no declared World Series winner by that boundary, the reviewed description sends the event to Other. Normal scheduling expectations do not erase that clause.

6. Save the current evidence

A useful audit record contains the event slug, component question, full description, active and closed flags, order-acceptance state, UTC timestamp, and official MLB result—not only a cropped price or countdown.

Resolution context is contract-specific: the October 31 top-level field does not replace the December 31 exceptional clause. If wording is clarified later, the exact current team contract and official result should be checked again rather than assuming this July snapshot remains controlling.

Why 2026 World Series search demand should rise

This hub was published 85 days before the World Series and is now refreshed at each elimination gate. It was selected for a scheduled, multi-wave demand curve—not because one team made news on a given day. With the field cut to four, demand now concentrates on the Championship Series matchups, their schedules, and the survivors' championship odds, while the exact event has grown from about $36.93 million in cumulative volume on July 30 to about $44.02 million on October 11.

Final-four wave

With four teams left, searches concentrate on Dodgers–Brewers and Guardians–Rays: series odds, game schedules, and each survivor's championship probability. The dated boards on this page show how the field repriced round by round.

Schedule and bracket wave

The bracket is now set through a potential Game 7 on October 31. Date questions center on the October 23 World Series start and the 2–3–2 patterns of both Championship Series, answered directly in the calendar section above.

Elimination-round waves

Each postseason round creates new qualification and elimination questions. Search demand may shift quickly from broad championship odds to a smaller set of surviving teams, so official results must outrank stale snippets.

Championship-resolution wave

Near the World Series, intent should concentrate around game dates, series status, winner scenarios, and how team contracts settle. The answer-first section and FAQ are designed to remain useful through that final wave.

Forecast, not a traffic or outcome guarantee: a fixed final regular-season date and an established championship event make rising attention plausible, but search volume, rankings, liquidity, forecast accuracy, and the eventual winner remain uncertain. This is an educational watchlist and resolution guide.

A practical World Series research workflow

Start with MLB's calendar

Verify the regular-season finale and, once published, postseason game dates on official MLB surfaces. Do not turn a prediction event's end field or an old search snippet into an official schedule.

Confirm the team can still win

Use official standings, qualification rules, brackets, and game results to establish whether a team remains eligible. “Unlikely” and “eliminated” are different states under the reviewed rule.

Read the exact team contract

Open the top-level event and the named team's component question. Check description, active and closed state, order acceptance, and any clarification before interpreting a quote or resolution.

Separate last trade from depth

The prediction-market odds guide and price-to-probability explainer show why last trade, bid, ask, spread, and available size should be recorded separately.

Measure uncertainty honestly

The risk-management guide and accuracy guide explain why market consensus can be wrong and why clear settlement evidence matters.

Use movers as leads

The biggest-movers watchlist can surface a team contract for investigation. It cannot identify whether the move came from an injury, result, thin order book, schedule news, or one large order.

Keep sports clusters distinct

The F1 guide, US Open guide, and Ballon d'Or guide share calendar-driven demand, but their qualification rules, official sources, and settlement terms do not transfer to baseball.

Understand the product

The prediction markets versus sports betting guide explains why a tradable binary contract and source-based settlement differ from a conventional fixed-odds ticket.
