Where the data comes from

Championship market races

Championship market data is derived from The Odds API. Sportsbook prices are transformed into normalized market shares for display. These shares describe the captured market and are not calibrated probabilities or predictions. Book coverage and timing can change between observations, and motion between observations is interpolated.

2026 MLB season review

The published race covers 30 teams across 218 daily captures from March 25 to October 28, 2026. Bubble area represents normalized title-market share averaged across three to five available sportsbooks; the panel varies by day. The final odds snapshot was October 28 at 4 a.m. Central, before Game 5. Closing bubble sizes illustrate the result rather than another market observation.

Historical Market Library

Each story provides its own scope, coverage and method, and links to any additional context sources. The original issue links are retained as historical records.

• Same top-three share. Very different football fields. — Each reporting book’s listed outright market was normalized to 100%. Team values were averaged across books listing that team, then the aggregate team means were rebased within each market. Six complete NFL boards and four college boards contributed to the July 31 capture; college team coverage varied by book.
• The Rams stand alone—but the NFL field runs deep — Each book’s complete 32-team board was normalized to 100%. Team values were averaged across six reporting books and the aggregate means were rebased within the market. The 1% line is descriptive; equal share for a 32-team field is 3.125%.
• Seven teams crowded the top. Most of the field sat below 1%. — Each book’s listed outright board was normalized to 100%. Team values were averaged across books listing that team, then the aggregate means were rebased within the market. Four books reported boards of different sizes, so coverage varied by team; a missing-as-zero sensitivity check preserved the field-shape interpretation.
• Philadelphia’s title chance nearly doubled in one hour — Title probabilities were normalized within the captured futures field. The headline comparison uses the same three reporting books at both displayed endpoints; later timing context is descriptive and does not establish causation.
• The week’s largest qualified MLB leader flip — Aggregate prices were normalized into market-implied win probabilities. The trace begins with the first coverage-qualified observation and ends at the final pre-game check; public lineup and schedule events are timing context, not causal claims.
• Boston’s title chance rose 80% during a 7–1 calendar stretch — Each daily futures field was normalized into aggregate no-vig title probability. The chart publishes transformed field movement and calendar context; it does not expose raw prices or claim the game sequence alone caused the repricing.
• Spain led the final World Cup title-market snapshot — Market-implied winner probabilities were normalized within each available daily futures field. Coverage varied by date and fell to one reporting book for the final snapshot, so the terminal split is presented as a bounded captured view.
• The week’s largest MLB leader flip — Aggregate prices were normalized into market-implied win probabilities. The trace begins with the first observation meeting the coverage threshold and ends at the final pre-game check; external events are timing context, not causal claims.
• Expected scoring fell 1.5 runs. The favorite finished almost unchanged. — The two panels share one pre-game time axis. The H2H panel shows transformed aggregate win probability; the total panel shows the transformed aggregate scoring line. The later report is displayed as chronology, not evidence of cause.
• The week’s largest MLB market flip — Aggregate prices were normalized into market-implied win probabilities. The displayed trace begins with the first observation meeting the coverage threshold and ends at the final pre-game check.
• Belgium led early. USA finished with the edge — The 90-minute result market was normalized across the available field into three aggregate states: USA, draw, and Belgium. Timing context is descriptive and does not establish causation.
• One clear World Series market favorite — Bubble area represents transformed aggregate no-vig championship probability. The page publishes the derived field and concentration measures, not raw prices or per-book rows.
