This market asks which team—Boston or Oklahoma City—will be leading at the end of the first half (with a third outcome for an exact tie). It matters to traders and fans who focus on short-term game dynamics rather than full-game results.
First-half markets isolate performance over the opening 24 minutes of play, so they emphasize starting lineups, opening strategies, and early matchups rather than late-game coaching adjustments. Boston and Oklahoma City typically bring different styles—one team may prioritize half-court execution while the other emphasizes pace and transition—and those stylistic differences often show up quickly. Because the market closes TBD, monitor lineups and injury reports before tip-off for the most relevant information.
Prices in this market reflect the crowd’s assessment of which side will be leading at halftime and update as new information arrives (injuries, starting lineups, in-game flow). Treat prices as real-time signals about market consensus, not guarantees of outcome.
The outcome is determined at the official end of the first half (halftime) as recorded by the league’s official game statistics; settlement timing depends on the platform’s processing of that official result.
There are three outcomes: Boston leading at halftime, Oklahoma City leading at halftime, or a tie. A tie occurs when both teams have the same official score at the end of the first half.
Late changes—such as a star being scratched or an unexpected starter—can materially change first-half expectations because this market covers only the opening half; traders typically react quickly to such news, so monitor verified injury reports and official starting lineup announcements.
No. The first-half winner market is settled based on the score at the conclusion of the first half; any overtime periods occur after the half and do not affect this market’s result.
Settlement in those situations follows the exchange’s published rules for canceled or postponed events; some markets are voided or settled using official determinations by the league or exchange, so consult KALSHI’s market-specific rules or support for the definitive policy.
