Kalshi
This market tracks whether the Chicago Cubs and St. Louis Cardinals game scheduled for May 30, 2026 at 7:15 PM EDT will extend into extra innings. On Kalshi, the probability of extra innings occurring stands at 7.5%. Resolution will be determined by the official outcome of the game as played on May 30, 2026, with the market settling based on whether the contest requires additional innings beyond the standard nine.
The market resolves on May 31, 2026, shortly after the conclusion of the Chicago C vs St. Louis game originally scheduled for May 30, 2026 at 7:15 PM EDT. Resolution is determined by whether the final result is decided within nine innings or requires extra innings to determine a winner. Once the game concludes and the official result is confirmed, the contract settles to either 100 cents (extra innings occurred) or 0 cents (game ended in regulation). Traders holding the winning side receive their payout immediately upon resolution.
Several factors could shift the probability before the game begins. Starting pitcher announcements, bullpen availability, and roster changes for either team will influence trader expectations about game length. Weather conditions—particularly wind speed and temperature—affect ball carry and scoring pace. Recent offensive and defensive trends, head-to-head matchup history, and any late-breaking injuries to key players can all trigger repricing. As game time approaches, market activity typically intensifies as traders incorporate final information. During the game itself, score progression and pitching changes will continue to move the market until the outcome is determined.
