Oklahoma won the 2026 College World Series, beating North Carolina in the championship round in Omaha—Kalshi's KXNCAABASEBALL-26 champion Categorical settled Oklahoma Yes on June 23, 2026. Kalshi ran the only prediction market book on the NCAA Division I baseball championship; neither Polymarket nor the other exchanges listed it, so this is a single-exchange record by design.

The widgets below preserve the resolved book—the full champion distribution across all 48 listed programs, the settled Omaha-qualifiers Multiple, and the price trajectory into the June 23 settlement. Settlement source: NCAA College World Series.

The champion pie on the left shows Kalshi's resolved KXNCAABASEBALL-26 distribution—Oklahoma settled to the top and every eliminated program carries its resolved 0%. On the right, the World Series Qualifiers Multiple settled once the eight-team Omaha field locked, marking which programs reached the College World Series. The gap between a team's qualifier outcome and its final champion price traces how far the book gave each run.

  • A clean single-exchange resolution. With no cross-exchange mirror, Kalshi's book carried all the price discovery into Omaha and resolved Oklahoma at the top—every other program compressed to zero through the final.
  • Elimination repricing. Each loss zeroed a name and redistributed its probability across the survivors; the pie moved fastest in the hours after each clinching game on the road to the title.
  • Trajectory over quotes. Between games the spreads stayed wide, so the history chart below is the cleaner read on how the book converged on Oklahoma than any single quote.
