final rationale
Mean of 5 draws (0.89, 0.90, 0.89, 0.90, 0.90). (0) Not yet resolved: Snowbird's site still shows its 2025/26 closed status, so Yes needs public lift-served skiing for passholders by Dec 12 ET. (a) About 75 days remain until the Dec 13 deadline. (b) Status quo: Snowbird's own calendar lists a tentative Nov 27, 2026 opening, conditions permitting, corroborated by Ski Utah, Powder, OnTheSnow and Unofficial Networks, giving a 16-day buffer. The base rate is strong: documented recent openings run from Nov 7 (2008) to Dec 7 (2025), including Nov 18, 2022, Nov 30, 2023 and Nov 28, 2024. (c) No: the slow-loading Nov-Dec pattern that Ski Utah, Deseret News and OpenSnow analogs flag for northern Utah, plus statewide drought and warmth, stalls base-building beyond the 16-day buffer; last year's slip already used 10 of those days. (d) Yes: normal or El Nino-boosted November storms and snowmaking allow a Thanksgiving-area opening, and even a repeat of last year's delay lands before Dec 13. The Kalshi anchor is 92% on a thin book (51/100); I shade slightly lower for the slow-start signal and drought baseline.

Planner reasoning
The Kalshi price is the anchor, and the sibling strikes in the KXSNOWBIRDOPEN series (other opening dates) show the full distribution the market implies. The base rate comes from Snowbird's historical opening dates (Wikipedia plus one targeted search), and the ENSO/La Niña winter outlook drives early-season snowfall in Utah. Resolution rests on Snowbird's own site and conditions pages.

report: current state
- [2026-09-29] Snowbird's official events calendar page currently lists Opening Day for the 2026-27 season as **"November 27, 2026 (Tentative)"**, explicitly conditions permitting; the page's meta-description text still reads "November 26" but the visible page content states November 27. https://www.snowbird.com/activities-events/events/events-calendar/opening-day/ - [2026-09-29] The same Snowbird page confirms the resort is currently in off-season/closed status for lift-served skiing: Snowbird is closed for lift-served skiing & riding for the 2025/26 season. The Tram remains open to foot passengers for scenic Tram Rides. Uphill travel is permitted. (page still shows prior-season status language, not yet updated for winter 2026-27 start). - [2026-09-10] Unofficial Networks' season-tracker reports on November 27, Jackson Hole, SilverStar, Snowbird and Sugar Bowl are currently aiming to begin their seasons , consistent with Snowbird's own target. - [2026-09-20] Salt Lake Tribune reported that Utah resorts have begun announcing 2026-27 opening dates, in a season expected to be influenced by a "super El Niño" pattern, though resorts had not yet changed plans based on that forecast as of the article date. https://www.sltrib.com/news/environment/2026/09/20/utah-ski-resort-2026-27-opening/ - [~2026-09-20] Ski Utah's resort page independently lists Snowbird's opening day is tentatively planned for November 27 , matching the resort's own target. - [~2026-09-22] Powder Magazine's compiled Utah opening-date list shows Snowbird: November 27, 2026 among other Utah resorts' announced (conditions-permitting) dates. - [~2026-09-22] Third-party tracker OnTheSnow projects Snowbird's Projected opening date Nov 27, 2026 , aligning with all other sources found. - [2025-12-05/07] For context, last season (2025-26) Snowbird's actual opening day was December 7, 2025 — later than its original target — after a slow-to-develop early season , with only Gad Valley/Chickadee terrain and the Gadzoom/Chickadee lifts running at open. https://snowbrains.com/snowbird-ut-sets-opening-day-for-december-7-after-challenging-early-season-stretch/ - [2026-09-29] No snow/weather-driven updates, early-snowfall reports, or revisions to the November 27 target date were found in the past 7-14 days; all recent sources (early-to-late September 2026) uniformly cite November 27 as the current tentative date, which is 16 days before the December 13 market deadline. - [2026-09-29] No news of a delay, resort closure, decommissioning, ownership change, or any operational disruption was found for Snowbird ahead of winter 2026-27. NOT FOUND: No official Snowbird press release (dated within the last 30 days) formally confirming or changing the November 27 tentative date beyond the events-calendar page; no current snowfall/snowpack data for the Wasatch/Little Cottonwood Canyon area as of late September 2026; no statement from Snowbird addressing the "super El Niño" forecast's effect on opening plans. BOTTOM LINE: Every current source (Snowbird's own site, Ski Utah, Powder, OnTheSnow, Unofficial Networks) converges on a tentative November 27, 2026 opening day — 16 days before the December 13 deadline — but all dates are explicitly "conditions permitting," and last season's comparable target slipped about 10 days (to Dec 7) due to poor early snowfall, showing real slippage risk even within the current margin.

- [2026-09-29] Snowbird's official events page currently lists "Our opening day for the 2026-27 season is November 26, conditions permitting." https://www.snowbird.com/activities-events/events/events-calendar/opening-day/ - [2026-09-10] A cross-resort tracker reports that on November 27, Jackson Hole, SilverStar, Snowbird and Sugar Bowl are currently aiming to begin their seasons, with Thanksgiving week expected to be when a large share of destination resorts are running. https://unofficialnetworks.com/2026/09/10/ski-season-opening-dates-2026-27/ - [2025-12-05] Historical precedent (2025-26 season, the most recent comparable case): Snowbird ultimately opened on "Sunday, Dec. 7" after its planned date slipped. https://townlift.com/2025/12/snowbird-set-to-open-for-2025-26-season-on-sunday/ - [2025-11-21] That slip was documented in real time: Snowbird pushed its opening day back from November 27th to the first week of December due to a slow start to the snow season. https://unofficialnetworks.com/2025/11/21/snowbird-pushed-back-opening-day/ - [2024-11-28] 2024-25 season: Snowbird opened on Thanksgiving Day, "Snowbird and Telluride are opening on Thanksgiving day after several inches of snow hit both resorts in the past 48 hours." (Nov 28, 2024) https://unofficialnetworks.com/2024/11/27/snowbird-telluride-opening-thanksgiving-day/ - [2023-11-23] 2023-24 season: "Snowbird, Utah, will open for the 2023-24 season for skiers and snowboarders on November 30, 2023." https://snowbrains.com/snowbird-ut-sets-opening-day-for-november-30/ - [2022-11-11] 2022-23 season: Snowbird moved up its opener from Nov. 30 to Nov. 18, the earliest start in resort history for that cycle. https://www.sltrib.com/sports/2022/10/05/alta-brian-head-park-city/ - [2022-05-16] Prior season (2021-22): "Snowbird opened on December 1st, 2021, and was open for 166-days when the lifts stopped turning." https://snowbrains.com/snowbird-closes-early-rapid-warming-2022-05-16-115310/ - [2008-11-06] Earliest example on record: "Opening Day is this Friday, November 7th" for the 2008-09 season, described as Snowbird's second-earliest opening ever. https://www.newschoolers.com/news/read/Snowbird-Announces-2nd-Earliest-Opening-Ever - [2022-10-06] Even in years without early powder, Snowbird's initial target dates cluster in the Nov 18–30 window (e.g., 2022-23 originally targeted Nov 30 before being moved earlier). https://unofficialnetworks.com/2022/10/06/snowbird-announces-opening-day/ - [2026-09-20] Utah resorts broadly are locking in similar Nov timelines for 2026-27, per a regional roundup of announced opening dates. https://www.sltrib.com/news/environment/2026/09/20/utah-ski-resort-2026-27-opening/ BOTTOM LINE: Over at least the last seven winters (2020-21 through 2025-26), Snowbird's actual public lift-served opening day has fallen between Nov 7 (2008) and Dec 7 (2025-26, the latest recent case) — every single instance before Dec 13. The 2026-27 target is currently Nov 26–27, so the base rate strongly favors a Yes outcome, with the main risk being a repeat of last year's slow-snow delay pattern, which still resolved by Dec 7. NOT FOUND: No documented instance in available sources of Snowbird's public/passholder lift opening occurring on or after Dec 13 in any recent season (going back to at least 2008); could not verify pre-2008 seasons or find an official Kalshi/other-venue market price for comparison (excluded per instructions).
report: yes case
YES means: Snowbird Ski Resort's first calendar day of documented Seasonal Opening Operations for the 2026‑27 season (at least one public-access lift serving open terrain) falls before December 13, 2026, resolving this market to Yes. - [2026-09-29] Snowbird's own events-calendar page, fetched directly, now labels the entry "Opening Day (Tentative)" with the on-page calendar field reading "November 27, 2026" (the stale meta-description still says "November 26"), confirming the resort's operative target is 16 days ahead of the Dec 13 deadline. https://www.snowbird.com/event/opening-day/ - [2026-08-11] OpenSnow's seasonal outlook (published Aug 11, 2026, updated ~1 month ago) forecasts an above-average snowfall signal for Alta, Snowbird, Brighton, Solitude, Snowbasin and the rest of the Wasatch this winter under the incoming super El Niño, a favorable backdrop for on-time or early opening compared to a below-average snow year. https://opensnow.com/news/post/2026-2027-winter-forecast-preview - [2026-08-11] The same OpenSnow forecast notes there is not a clear signal in either direction for early season snow (November-December) for Utah, meaning meteorologists see no strong reason to expect an unusually late start — the risk of a Dec-13+ opening is not elevated by this year's climate pattern specifically. - [2008-11-06] Extending the historical record further back than prior reports: Snowbird's earliest documented modern opening was Nov. 7, 2008, described as the resort's second-earliest opening ever, showing the historical range runs from very early November through the latest known case (Dec. 7, 2025) — never approaching Dec. 13. https://www.newschoolers.com/news/read/Snowbird-Announces-2nd-Earliest-Opening-Ever - [2022-10-05] In the one recent year with unusually strong early snow, Snowbird moved its opener up from a planned Nov. 30 to Nov. 18, 2022, illustrating that when conditions cooperate the resort opens with nearly a month of buffer before the Dec 13 deadline. https://www.sltrib.com/sports/2022/10/05/alta-brian-head-park-city/ - [2025-12-04] Neighboring Alta — which shares lift infrastructure and similar snowpack exposure in Little Cottonwood Canyon — also slipped its 2025-26 opening due to a dry start but still opened the following week, underscoring that even a "bad" early season historically resolves well before mid-December for this micro-climate. https://www.powder.com/news/alta-announces-opening-day-2025 - [2026-09-27] The Ski Utah snow report as of Sept. 27, 2026 shows only scattered off-season showers with showers to start the upcoming week with warming and drying later this week into next weekend; a few flakes are possible in the high Uintas and perhaps highest peaks of the Wasatch — consistent with normal late-September conditions and no sign of an anomalously slow start comparable to what caused last year's delay. https://www.skiutah.com/snowreport/ - [2026-09-14] Ikon Pass's opening-date tracker (last updated Sept. 14, 2026) independently corroborates that Wasatch-area destinations, including Snowbird, are in the normal cycle of announcing tentative late-November 2026-27 opening dates. https://www.ikonpass.com/en/opening-closing-dates - [2026-09-22] OnTheSnow's Utah projected-openings tracker lists the 2026/27 Utah ski season starting broadly from Nov. 21, 2026, placing Snowbird's Nov. 27 target squarely within the normal cluster of Utah resort openings, not as an outlier requiring exceptional conditions. https://www.onthesnow.com/utah/projected-openings BOTTOM LINE: Every primary and secondary source — Snowbird's own tentative Nov. 27, 2026 calendar listing, cross-resort trackers, and a seven-plus-year historical record (earliest Nov. 7, latest Dec. 7) — supports a strong likelihood of opening before Dec. 13, 2026, and this year's neutral-to-favorable early-season snow outlook gives no specific reason to expect the kind of prolonged, multi-week delay that would be needed to push opening past the deadline. NOT FOUND: No live October/November 2026 snowfall or SNOTEL data yet (too early in the season to confirm actual accumulation); no official Snowbird press release beyond the tentative calendar page confirming or revising the Nov. 27 date; no resort statement addressing how the super El Niño outlook specifically affects opening timing.
report: no case
YES means: Snowbird conducts Seasonal Opening Operations (at least one public passenger lift serving open downhill terrain, accessible to season-pass holders without extra purchase) on any calendar day before Dec 13, 2026, Eastern Time. - [2026-09-19] Statewide, drought currently covers the entire state heading into the 2026-27 water year: "As of Sept. 17, 100% of Utah was experiencing some form of drought." Reservoir storage is also below normal, per the same Division of Water Resources report, indicating a dry starting baseline for the season rather than a wet one. https://www.western-water.com/2026/09/19/utah-enters-new-water-year-with-drought-low-reservoirs/ - [2026-09-21] A retired NWS hydrologist briefing the Utah Avalanche Center cautions that predicting Wasatch outcomes months out is unreliable this year: exactly where the jet stream sets up will determine whether the central and northern Wasatch repeatedly get caught in the storm track or mostly receive the edges of storms passing farther south, and "We have something that could be exceptionally good or exceptionally poor." https://unofficialnetworks.com/2026/09/21/utah-el-nino-ski-season-forecast-2026-27/ - [2026-08/09] Multiple seasonal outlooks (Ski Utah, Deseret News, OpenSnow) explicitly flag a slow northern-Utah start as the base case for this El Niño: "Northern Utah's forecast is a little more 'trust the process' — a potentially slow-loading November and December, with real reason to believe things turn on later in the season." This directly targets the Nov-Dec window that matters for the Dec 13 deadline. https://www.deseret.com/lifestyle/2026/08/03/super-el-nino-utah-winter-snow-ski-resorts/ - [2026-08-11] OpenSnow's own historical-analog work for this El Niño type reinforces the same timing risk: "historical analogs favor a somewhat slower start in December, followed by a strong signal for above-normal snow" later — i.e., the analog years tend to open late, not early. https://opensnow.com/news/post/2026-2027-winter-forecast-preview - [2026-08-06] NOAA's Climate Prediction Center's own July 16 seasonal outlook, cited by TownLift, favors warmth over the exact window that determines opening: the developing pattern is expected to favor warmer-than-normal temperatures across much of the western and northern US, with the December-through-February forecast favoring below-normal precipitation across parts of the northern Rockies — a warm/dry lean for the north is the opposite of what's needed for early snowmaking and natural base-building. https://townlift.com/2026/08/strong-el-nino-could-tilt-utahs-winter-warmer-and-drier/ - [2026-09-22] Independent tracker of CPC's latest official Dec–Feb map shows Utah sitting in a genuinely uninformative "equal chances" zone on both temperature and precipitation, meaning the seasonal signal gives no lean toward an early, snow-rich start that would guarantee opening well before Dec 13. https://mywild.report/winter-forecast-utah - [2025-11-21] Mechanism precedent directly on point: last season, Snowbird's identical Nov 27 target was scrapped once cumulative snowfall reached only "19 inches of snow, 10 of which came in the past 7 days" by Nov 21, forcing a push into December — showing how thin a margin (just ~16 days between target and deadline) can evaporate with even a modest early-season lull. https://unofficialnetworks.com/2025/11/21/snowbird-pushed-back-opening-day/ - [1997-2026 pattern] A regional comparative outlook notes that for the Wasatch specifically, super/strong El Niño history is not a reliable predictor either way: "If you ski the Wasatch or the I-70 corridor, strong El Niño winters tell you close to nothing." This undercuts any narrative that the "super El Niño" branding guarantees an on-time or early opening. https://www.disasteraware.com/news-event/el-nino-ski-season-2026-27 - [2026-09-09 approx] Snowbird's own events-calendar language remains explicitly conditional, not a commitment: the page states the tentative date "conditions permitting," and payout rules exclude "Scheduled, projected, or announced opening dates" from counting — meaning even Snowbird's own public Nov 26/27 announcement carries zero resolution weight if snow/temperature conditions do not cooperate by then. - [Structural note] The market's 16-day buffer (Nov 27 target vs. Dec 13 deadline) is smaller than the 2025-26 season's actual slip: the target-to-actual delay last year (Nov 27 → Dec 7) consumed 10 of those 16 days already just from a routine slow start, per the Nov 21 and Dec 5 reporting cited above and in prior team research — leaving very little additional cushion if this year's slow-loading-November signal (per Ski Utah/Deseret/OpenSnow) proves even slightly worse. BOTTOM LINE: While Snowbird has opened before Dec 13 in every recent season on record, this year's setup is unusually snowpack-adverse for the specific pre-deadline window: statewide drought entering the water year, a documented "slow-loading November and December" consensus among Ski Utah, Deseret News and OpenSnow analysts, a warmer-leaning/below-normal-precipitation CPC signal for northern Utah, and a directly analogous 2025 precedent where an identical Nov 27 target slipped 10 days (nearly the entire current buffer) due to thin natural snowfall — all of which argue that a repeat or worse slip past Dec 13 is a live, non-trivial risk rather than a remote tail scenario. NOT FOUND: No current (late-September 2026) snowpack/SWE telemetry for Little Cottonwood Canyon specifically; no official Snowbird statement addressing the El Niño outlook or drought conditions; no confirmed news of any delay announcement yet for 2026-27 (none expected this early, as delays historically are announced in mid-to-late November).

(0) Not yet resolved: Snowbird's site still shows its 2025/26 closed status, so Yes needs public lift-served skiing for passholders by Dec 12 ET. (a) About 75 days remain until the Dec 13 deadline. (b) Status quo: Snowbird's own calendar lists a tentative Nov 27, 2026 opening, conditions permitting, corroborated by Ski Utah, Powder, OnTheSnow and Unofficial Networks, giving a 16-day buffer. The base rate is strong: documented recent openings run from Nov 7 (2008) to Dec 7 (2025), including Nov 18, 2022, Nov 30, 2023 and Nov 28, 2024. (c) No: the slow-loading Nov-Dec pattern that Ski Utah, Deseret News and OpenSnow analogs flag for northern Utah, plus statewide drought and warmth, stalls base-building beyond the 16-day buffer; last year's slip already used 10 of those days. (d) Yes: normal or El Nino-boosted November storms and snowmaking allow a Thanksgiving-area opening, and even a repeat of last year's delay lands before Dec 13. The Kalshi anchor is 92% on a thin book (51/100); I shade slightly lower for the slow-start signal and drought baseline.

(0) Nothing has resolved yet. Snowbird's site still shows closed status for the 2025/26 season and lists a tentative 2026-27 opening of Nov 27, conditions permitting. (a) The deadline is Dec 12 inclusive, about 10.5 weeks away. That leaves a 16-day buffer after the target date. (b) Status quo: Snowbird opens around its late-November target, as it has in essentially every recent season. The documented range runs from Nov 7, 2008 to Dec 7, 2025, and no recent opening was found on or after Dec 13. (c) NO scenario: El Niño brings the 'slow-loading November/December' that Ski Utah, Deseret News and OpenSnow analogs flag for northern Utah. Add the statewide drought entering the water year and a warm lean that limits snowmaking, and the Nov 27 target slips more than last year's 10-day delay, pushing past Dec 12. (d) YES scenario: normal or even modest early storms plus snowmaking on the Gadzoom/Chickadee area let Snowbird open Nov 27 or within a week or two after. That happened even in the poor 2025-26 start. The Kalshi price of 92% (thin book, 51/100 spread) fits this base rate. The adverse early-season outlook and last year's slip are known signals that justify shading slightly lower, to about 90%.

(0) Not resolved. Snowbird's site still shows 2025/26 closed-season language. Its events calendar lists a tentative 2026-27 opening of Nov 27 (the meta text says Nov 26), conditions permitting, and scheduled dates do not count under the rules. (a) The deadline is Dec 13, about 10.5 weeks away, leaving a 16-day buffer after the target date. (b) Status quo: Snowbird historically opens between early November and early December. Every recent documented season opened before Dec 13, from Nov 7, 2008 to the latest recent case of Dec 7, 2025, so the default path is Yes. (c) No: a warm, dry November-December under a statewide drought baseline. OpenSnow, Ski Utah and Deseret News analysts flag a 'slow-loading' early season for northern Utah in this El Niño. The Nov 27 target could slip further than last year's 10 days and push opening past Dec 12. (d) Yes: normal or above-normal early storms plus snowmaking on the Gad Valley/Chickadee terrain allow a late-November or early-December opening, as in nearly every past season. The Kalshi price of 92% sits on a very wide 51/100 spread, so it is a weak anchor. I shade slightly below it because of the specific slow-start El Niño signal and the drought baseline, while the long historical record keeps Yes strongly favored.

(0) The condition is not already met: Snowbird’s website says lift-served skiing is currently closed and only scenic Tram rides and uphill travel are available, so qualifying public downhill operations must begin by December 12 Eastern Time. (a) From September 29, roughly 74 days remain through the last qualifying day, while Snowbird’s official tentative opening date is November 27, providing a 15-day operational cushion. (b) If nothing changes and the resort remains closed, the outcome is No, although the current plan and normal seasonal pattern strongly favor a change. (c) No results if drought, warmth, and a slow-loading early El Niño storm pattern prevent adequate snowmaking or natural coverage until December 13 or later, as last season’s November 27 target already slipped to December 7. (d) Yes results if Snowbird opens on or near November 27, or experiences a more modest delay while still running at least one qualifying public lift by December 12; every recent documented season opened before December 13. Kalshi’s 92% Yes price is the anchor, but I reduce it to 90% because the conditional date, statewide drought, and mixed early-season outlook create a specific late-opening risk that is somewhat greater than the market price implies.

(0) The condition has not already been met: Snowbird’s website says lift-served skiing is closed and only scenic Tram rides and uphill travel are available, so qualifying public lift operations must begin before December 13. (a) From September 29, about 74 days remain until the last qualifying day, December 12, and Snowbird’s tentative November 27 opening leaves a 16-day buffer. (b) If current plans hold, Snowbird opens November 27 and the market resolves Yes; the official calendar and several independent trackers agree on that target. (c) No would result from a warm, dry early season delaying sufficient terrain and lift operations until December 13 or later, a credible risk given statewide drought, uncertain El Niño effects, and forecasts suggesting a potentially slow northern-Utah start. (d) Yes results if ordinary early-season snowfall or snowmaking permits even one qualifying public/passholder lift and run to open by December 12; every documented recent season cited opened by December 7, including last season after a ten-day delay. I anchor near Kalshi’s 92% Yes price but reduce it to 90% because the tentative date does not itself count, the bid-ask spread is exceptionally wide at 51%-100%, and live snowpack evidence is not yet available.

90% (65% confidence)
Yes: 90% No: 10%
Mean of 5 draws (0.89, 0.90, 0.89, 0.90, 0.90). (0) Not yet resolved: Snowbird's site still shows its 2025/26 closed status, so Yes needs public lift-served skiing for passholders by Dec 12 ET. (a) About 75 days remain until the Dec 13 deadline. (b) Status quo: Snowbird's own calendar lists a tentative Nov 27, 2026 opening, conditions permitting, corroborated by Ski Utah, Powder, OnTheSnow and Unofficial Networks, giving a 16-day buffer. The base rate is strong: documented recent openings run from Nov 7 (2008) to Dec 7 (2025), including Nov 18, 2022, Nov 30, 2023 and Nov 28, 2024. (c) No: the slow-loading Nov-Dec pattern that Ski Utah, Deseret News and OpenSnow analogs flag for northern Utah, plus statewide drought and warmth, stalls base-building beyond the 16-day buffer; last year's slip already used 10 of those days. (d) Yes: normal or El Nino-boosted November storms and snowmaking allow a Thanksgiving-area opening, and even a repeat of last year's delay lands before Dec 13. The Kalshi anchor is 92% on a thin book (51/100); I shade slightly lower for the slow-start signal and drought baseline.
