New York Y vs San Francisco: Home Runs

The 19 options correspond to discrete home-run outcomes or threshold bands for total home runs in the game; check the market page for exact labels and how each outcome is worded before trading.

The market close time is listed as TBD on the event page; typically, platforms close markets before the game starts and resolve them after the official game is completed using the game’s final statistics—watch KALSHI for the posted close and resolution schedule.

Resolution will follow the market’s stated rules on KALSHI and rely on the official MLB game record (box score and play-by-play) as the authoritative source for home-run counts, including any plays subject to review that are later overturned in the official record.

Key movers include the scheduled starting pitchers for each team, the teams’ primary power hitters (especially those facing favorable handedness), any late scratches or lineup changes, and relief pitchers who tend to give up homers.

These events can materially change home-run expectations: lineup changes that remove or add power hitters, unexpected starting-pitcher changes, and shifts in wind or precipitation are all information that typically prompts rapid price updates—monitor official team reports and weather forecasts and expect markets to react quickly.
