This market lets traders take positions on the first-half spread between St. John's and Duke — essentially which team will lead and by how many points at halftime. First-half markets matter for traders focused on early-game dynamics, lineup decisions, and live hedging strategies.
St. John's and Duke are college basketball programs with distinct histories and styles; matchups between them attract attention because of contrasting personnel, coaching philosophies, and fan interest. First-half outcomes are influenced by how each team approaches the opening period — pace, defensive focus, and which players start — and these factors can differ from full-game tendencies.
Market prices reflect aggregated beliefs about the likely halftime point margin and move as new information arrives (lineups, injuries, matchup news). Interpret prices as the market consensus about the expected first-half spread at any given moment, not as fixed predictions.
The listed close time is TBD; the platform will display the final close time for this market — most first-half markets close at or shortly before tip-off so positions cannot be entered once the game starts.
The outcomes correspond to a set of discrete first-half spread bins covering different possible halftime margins; settlement is based on the official halftime score difference and which outcome bin contains that margin.
Late scratches or lineup changes typically move the market quickly; traders often wait for official confirmations from team announcements or league sources before taking or adjusting positions because those changes materially affect first-half matchups.
Resolution follows KALSHI's official market rules for event interruptions; if the first half is not completed the platform’s stated settlement policy for incomplete events will determine whether the market is voided or resolved in another way — check KALSHI’s rules page for specifics.
Sharp early indicators include first-half shooting efficiency (especially from three-point range), turnover differential, offensive rebounding that creates second-chance points, and whether primary scorers draw early fouls limiting minutes; these stats often cause rapid price movement.
