About This Event
Sayaka Ishii vs Elina Avanesyan Set 2 (Oct 16) If X wins set 2 in the Sayaka Ishii vs Elina Avanesyan professional tennis match in the 2026 WTA Osaka Qualification Round 1, then the market resolves to Yes. The following market refers to the Sayaka Ishii vs Elina Avanesyan professional tennis match in the 2026 WTA Osaka Qualification Round 1. If the match does not occur, signaled by a ball being played, due to a player injury, walkover, forfeiture, or any other cancellation, all before the match starts, the market will resolve to a fair price in accordance with the rules. If this match is postponed or delayed, the market will remain open and close after the rescheduled match has finished, within two weeks. If a retirement occurs, all markets that can be unconditionally settled based on play already completed will resolve accordingly. Any markets that cannot be unconditionally settled will resolve to Fair Market Price, as determined at the sole discretion of the Exchange. Kalshi is not affiliated, associated, authorized, endorsed by, or in any way officially connected with the Governing League. All trademarks, logos, and brand names are the property of their respective owners. This market will close and expire after the event occurs.

What the contract measures
The supplied source is a Kalshi event for the set 2 winner in the Sayaka Ishii vs Elina Avanesyan professional tennis match, part of the 2026 WTA Osaka Qualification Round 1 [1]. The rules state that "If X wins set 2 in the Sayaka Ishii vs Elina Avanesyan professional tennis match," the market "resolves to Yes" [1]. The evidence includes two binary markets: one asks whether Elina Avanesyan wins set 2, and the other asks whether Sayaka Ishii wins set 2 [1].
The rules also cover disruptions. If the match is postponed or delayed, "the market will remain open and close after the rescheduled match has finished, within two weeks" [1]. If a player retires, markets that can be settled from completed play "will resolve accordingly," and others "will resolve to Fair Market Price" [1]. These provisions affect how a market settles, so they matter when comparing contracts.
Reading the snapshot
The provider observation time is 2026-10-17 03:00 UTC, and the source was retrieved at 2026-10-17 04:00 UTC [1]. These are snapshot times, not live prices. The listed market end date is 2026-10-31 02:30 UTC for both contracts, but the event excerpt says the market "will close and expire after the event occurs," and it lists the event end time as not supplied [1]. The end date therefore should not be read as the time the match is expected to finish.
In this snapshot, the Avanesyan set 2 contract shows a Yes price of 0.735 and a No price of 0.265 [1]. The Ishii set 2 contract shows a Yes price of 0.265 and a No price of 0.735 [1]. Because these are mirror contracts for the same set, the two Yes prices sum to 1.00 here. These are quoted snapshot prices, not executable quotes or verified probabilities.
The sample includes all saved markets for this event, with two of two markets included and no partial sample flag [1]. This covers only the saved provider event for this set, not every possible outcome in the match.
What remains uncertain
The evidence does not show the match result, whether play has started, or any reason the prices are where they are. Trading volume and the number of participants are not supplied, so the snapshot does not indicate liquidity. Because only one provider source appears here, these figures should not be compared with prices from other platforms or other events without matching the exact wording, settlement rules, and close times.

Saved Oct 17, 2026 UTCOverview
This PredictPedia entry covers a Kalshi contract on the second set of a professional tennis match between Sayaka Ishii and Elina Avanesyan, listed under the event title "Sayaka Ishii vs Elina Avanesyan: Set 2 Winner" [1]. The provider describes the match as taking place in the 2026 WTA Osaka Qualification Round 1, and the event label refers to "Set 2 (Oct 16)" [1]. The label is part of the event title, so it should be read as the provider's naming rather than a confirmed match date. The contract is a binary market. Under the rules, if the named player wins set 2 in the match, the market resolves to Yes [1]. The saved event contains two markets: one asks whether Elina Avanesyan wins set 2, and the other asks whether Sayaka Ishii wins set 2 [1]. Each market has Yes and No outcomes, so the two markets mirror each other within this event. At the provider observation time, the Avanesyan set 2 market showed a Yes price of 0.735 and a No price of 0.265, while the Ishii set 2 market showed a Yes price of 0.265 and a No price of 0.735 [1]. These figures are price snapshots from the provider data. They are not executable quotes, and they should not be read as verified probabilities of the outcome. The rules address several disruptions. If the match does not take place because of an injury, walkover, forfeiture, or another cancellation before play starts, the market resolves to a fair price under the rules [1]. If the match is postponed or delayed, the market stays open and closes after the rescheduled match finishes, within two weeks [1]. If a player retires, markets that can be settled unconditionally on completed play resolve on that basis, and any that cannot resolve to Fair Market Price, as determined at the Exchange's sole discretion [1]. The rules also state that the market will close and expire after the event occurs [1]. The provider lists the market status as active and states that the listed end time was not supplied [1]. The end date in the market data is a provider field and does not establish when the match will be played or when the contract will close in practice, since the rules tie closing to the event itself [1]. The rules also state that Kalshi is not affiliated with the governing league [1].
Why It Matters
The contract measures a single result: which player wins the second set of the named match [1]. Because the two markets in the saved event are tied to the same set, they give opposing Yes outcomes for the same underlying result [1]. The rules define how the contract behaves if the match is cancelled before play, postponed, or ended by retirement, so the resolution depends on those terms as much as on the set score [1]. Traders and readers can use the rules to understand that a price reflects the contract terms at a moment in time, not a settled result [1].
