This market asks how large the scoring margin will be between Idaho and Montana State at the end of the first half; it matters because first-half spreads isolate early-game performance and can reflect coaching and matchup dynamics distinct from full-game outcomes.
Idaho and Montana State are collegiate football programs that have competed regionally and within similar conferences; past meetings and seasonal form influence expectations for how the teams perform early in games. First-half markets focus on 30 minutes of game action and can be driven by starting lineups, play-calling tendencies, and in-game adjustments rather than late-game depth or garbage-time scoring.
Market prices indicate the crowd's assessment of which spread-range outcome is most likely for the first half; higher prices mean fewer traders expect that specific outcome, while lower prices mean more market interest. Check the market page for live prices and settlement rules to interpret current market signals.
This market settles based on the official point differential (Idaho minus Montana State, or vice versa as specified) at the conclusion of the first half as recorded by the game's official scorer; the outcome that contains that margin is the winning contract.
The 11 outcomes correspond to discrete spread-range buckets covering possible first-half margins (for example, a set of contiguous margin intervals); each contract represents one of those margin ranges and wins if the official first-half margin falls inside it.
The listed close time is TBD for this market; typically first-half spread markets close shortly before kickoff to allow for roster and injury information to be incorporated—monitor the Idaho vs Montana St.: First Half Spread page on KALSHI for the official trading window and any updates.
In-play or pregame injuries influence trader behavior and therefore market prices, but settlement is always determined by the official first-half score; if a player is ruled out before kickoff that information will normally be reflected in prices, while resolution does not retroactively change which outcome wins.
If the first half is not completed or the game is canceled, the market will follow KALSHI's event rules for voiding, partial settlement, or delayed resolution; check the specific market rules on the platform for the definitive policy in those scenarios.
