What the contract measures

The Kalshi event "Duke vs Virginia: 1st Half Spread" covers the college football game originally scheduled for October 23, 2026 [1]. Each contract asks whether one team wins the first half by more than a stated number of points. The source says "If Virginia wins by more than X points in the 1st half... then the market resolves to Yes" and that "Only points scored during the 1st half of play count towards this market" [1]. Full-game results do not count.

The rules also address postponement. If the game is postponed but begins within 48 hours of its originally scheduled start time, "the market will remain open and resolve based on the official final result." If it does not start within 48 hours, "the market will resolve to a fair price" [1]. Contract rules describe how resolution works. They do not indicate that any postponement has occurred.

Listed close times need care. The event page says "Listed end time: not supplied" [1]. The market records carry an end date of 2026-10-25T23:00:00.000Z [1]. Treat that timestamp as a recorded field, not a confirmed resolution date.

Reading the snapshot

The provider observed these prices at 2026-10-20T03:00:06Z, and the record was retrieved at 2026-10-20T05:03:03Z [1]. These are historical snapshots from earlier today, not live quotes. They are not executable prices and are not verified probabilities.

Within each row, Yes and No prices sum to 1.00, so each row is one binary contract. Selected Yes prices include:

• Virginia by over 1.5 points: 0.45 [1]
• Virginia by over 2.5 points: 0.43 [1]
• Duke by over 2.5 points: 0.40 [1]
• Virginia by over 10.5 points: 0.19 [1]
• Duke by over 6.5 points: 0.235 [1]

Each threshold is a separate contract. Comparing the Virginia and Duke rows is a comparison of different questions, not a single probability. The data does not support averaging across thresholds or treating different contracts as an arbitrage opportunity.

What remains uncertain

The sample is partial. The record shows 12 of 21 markets for this event [1]. The included markets are a selection, not the full field, and the record gives no explanation for the omitted markets. The record also lacks volume or liquidity details, so it cannot show how deep any market is or how many traders are involved. The snapshot does not explain why prices are at these levels, and it contains no information on the game's status after the observation time.
