Snapshot observed 2026-10-19T21:00:06.045Z. This event is archived. This analysis describes that snapshot and is not a live news update.

What the contract measures

Two binary contracts from the same Kalshi event, both tied to the same tennis match, are included in this snapshot. One pays Yes if Arseneault / Lacasse wins, and the other pays Yes if Brantmeier / Tanguilig wins. The rules state that the match must occur, "signaled by a ball being played," for the market to resolve to Yes or No [1]. If the match is cancelled before it starts, "all markets will resolve to $0.50" [1]. If a team "withdraws or forfeits after a match has started, that team will resolve to No" [1].

The rules also address scheduling. If the match is postponed or delayed, "the market will remain open and close after the rescheduled match has finished, within two weeks" [1]. The saved market records list an end date of 2026-11-02T16:00:00.000Z for both contracts, but the rules say the market "will close and expire after a winner is declared" [1]. The listed end time is therefore a provider close field, not a confirmed match date, and the excerpt itself notes that the listed end time was "not supplied" [1].

Reading the snapshot

The provider observation time is 2026-10-19T21:00:06.045Z, and the source was retrieved on 2026-10-26T15:33:37.933Z [1]. The prices below describe the October 19 observation only. They are not current prices, executable quotes, or verified probabilities.

• Arseneault / Lacasse wins: Yes 0.525, No 0.475 [1]
• Brantmeier / Tanguilig wins: Yes 0.455, No 0.545 [1]

Each contract's Yes and No prices sum to 1 in the saved record. The two Yes prices are separate contracts with separate rules, so their gap should not be read as an arbitrage opportunity. The snapshot does not explain why prices were where they were.

The saved market coverage includes 2 of 2 markets for this event, and the sample is not marked partial [1]. This describes only the saved provider event. The sample warning states that the providers may not list every possible real-world outcome [1], so this should not be treated as the full set of possible results.

What remains uncertain

The evidence does not show whether the match was played, postponed, cancelled, or forfeited after the observation time. It also does not show the actual resolution. The saved status was "active" [1], but that describes the record at observation, not the position today. Volume data was not used here because volume does not measure liquidity or the number of traders.
