Story so far

Up to date

The market has now seen a second sharp re-pricing tied to the Giants-Guardians game: after San Francisco's 1-0 win had crushed the extra-innings Yes to near zero, the Cleveland Guardians side later surged from 0 to 0.9995. The move appears to line up with the game finishing 5-2 for Cleveland, with no separate confirmed catalyst.

This story reflects the latest meaningful update PolySays has published.

Latest update

Guardians extra-innings market surged after Cleveland finished Giants game 5-2

The Cleveland Guardians’ extra-innings market jumped from 0 to 0.9995 between August 14, 2026 and August 20, 2026 after Cleveland’s 5-2 win over San Francisco was reported. The move likely coincided with the game’s final result, which removed extra-innings uncertainty.

Why this matters

Market moves can show where expectations are changing. PolySays adds the source trail so the price is not treated as proof on its own.

Known catalysts

  • The earlier plunge appeared to coincide with San Francisco's 1-0 win, which removed extra-innings probability.
  • The new surge appears to coincide with Cleveland's eventual 5-2 result, which also removed extra-innings uncertainty.
  • Polymarket snapshot changes show a very large price shift over the observed window.

Unresolved questions

  • Whether any postgame timing or reporting details amplified the Cleveland-side surge beyond the final score.
  • Whether the market was already repricing before the final result was fully reflected.
  • Whether this was only a reaction to game outcome or included any platform-specific re-pricing.
