What this workspace tracks

The 2026 MLB World Series is a cross-exchange Categorical—Kalshi and Polymarket both list every team, with Kalshi carrying the higher 24h volume on most days while Polymarket runs neck-and-neck on open interest among retail-sized accounts. This workspace pairs both championship books at the top, splits the pennant race into AL and NL on Kalshi, and stacks the four major Kalshi player-award Categoricals (NL Cy Young, AL Cy Young, NL MVP, AL MVP) underneath so the cross-section between team strength and individual hardware is readable at a glance.

World Series settlement: on or before November 1, 2026.

Kalshi and Polymarket both list the championship as a 30-team Categorical. Full distributions side by side—the cross-exchange spread on the favorites is the cleanest read.

Kalshi's AL and NL Champion Categoricals are the cleanest pennant-race book in the catalog. Polymarket also lists league champions but at materially thinner volume; the AL/NL pies on Kalshi are the canonical reads here.

Player awards trade on Kalshi at meaningful volume across the season. NL Cy Young carries the heaviest book of the four; MVP Categoricals tend to sharpen in the August/September window as the standings settle.

  • AL/NL spread vs. championship pie. The product of the AL leader and NL leader probabilities equals the market's implied chance of a specific Finals matchup. When that product diverges meaningfully from the top championship slice, one of the two pennant books is leaning the wrong way.
  • Kalshi vs. Polymarket on the favorite. Kalshi tends to lead Polymarket by a few cents on the World Series favorite during regular-season news cycles; the gap usually compresses post-trade-deadline.
  • Cy Young as a starter-pitcher proxy. Teams whose ace is leading the Cy Young pie carry a structural edge into October. Watch when the team's championship slice repricing trails the pitcher's award repricing.
  • Trade deadline (late July) is the next major repricing window. Expect stepwise moves in division and championship books as contender rosters consolidate.
