Mean of 5 draws (0.92, 0.93, 0.90, 0.91, 0.93). (0) The condition is not yet met. December 2026 data will not be published until about mid-January 2027, and the StreetEasy dashboard returned a 403, so the latest confirmed StreetEasy figure is May 2026 at $4,199. (a) About 2.5 months of market time remain before the December reading, and the market closes 2027-01-31. (b) Status quo strongly favors Yes. StreetEasy's citywide median has been above $3,800 every reported month of 2026 ($3,950 in February, $3,995 in March, $4,199 in May), YoY growth has run 7–8%, and November 2025 was already $3,875. A 7% YoY gain on a December 2025 base near $3,800–3,875 implies roughly $4,050–4,150. The NYCEDC snapshot citing the StreetEasy Rent Index shows asking rents still rising through August, and Corcoran and Miller report record Manhattan and Brooklyn rents. (c) No path: a sharp fall slowdown (OpenIgloo shows a 3.6% MoM drop in September, though it uses a different methodology), plus the normal December seasonal trough and a compositional shift toward cheaper listings. Together these would have to push the median down more than 9.5% from the May peak, larger than the usual peak-to-winter seasonal decline. (d) Yes path: a normal seasonal dip of 4–8% off a summer peak near or above $4,200 leaves December around $3,950–4,100. The Kalshi anchor is 91–93% after slipping from 97%, possibly reflecting the softer fall signals. I see no specific unpriced information to move far, so I hold about 0.92 and keep some weight on the data gap since May and on metric or composition volatility.

- [2026-03-12] StreetEasy's February 2026 report: the citywide median asking rent increased 8.2% year-over-year to $3,950 with Manhattan at $4,700, Brooklyn at $3,750, Queens at $3,150. (streeteasy.com/blog/manhattan-rental-inventory-falls-24th-consecutive-month/) - [2026-06-11] StreetEasy's May 2026 report, the latest monthly citywide rent figure StreetEasy has published to date: the citywide median asking rent rose 7.3% year-over-year to $4,199 in May, a new high since StreetEasy began tracking the data in 2010 , with Manhattan reaching a new high of $4,927 and Brooklyn hitting a record $3,895 . (streeteasy.com/blog/nyc-rental-market-update-one-year-after-fare-act/) - [2026-06-11] In that same report, Queens' median asking rent climbed 6.4% to $3,350, its highest since July 2025 . (streeteasy.com/blog/nyc-rental-market-update-one-year-after-fare-act/) - [2025-12-18 (published Jan 2026, reporting Nov 2025 data)] StreetEasy's prior report: the citywide median asking rent was $3,875 in November, up 7.6% from a year ago . (streeteasy.com/blog/fare-act-six-months-market-impacts/) - [2026-09-xx] NYCEDC's September 2026 Economic Snapshot (using StreetEasy data) notes the StreetEasy Rent Index stood at 136.1 in August 2026, up from 135.1 in July, and that residential asking rents increased for the seventh consecutive month , with the citywide median asking rent having risen $403 over the past two years to nearly $4,000, while rental inventory fell 14 percent (edc.nyc PDF). This confirms rent growth continued through at least August 2026, though this specific dollar figure cites CoStar data rather than StreetEasy directly. - [2026-09-01] StreetEasy's blog "Market Reports" index shows no dedicated monthly citywide rent report between the June 11, 2026 post (May data) and October 9, 2026; subsequent posts shifted to sales-market topics ("Luxury homes lead NYC's summer sales momentum," "More than half of families with children in NYC are rent-burdened," "NYC homes selling above asking at highest rate in four years"), meaning StreetEasy has not yet published its own June, July, August, or September citywide median asking rent figures as of today. (streeteasy.com/blog/nyc-housing-market-data/market-reports/) - [2026-09-08] A separate (non-StreetEasy) Corcoran "Inhabit" report for August 2026 shows Manhattan's rental market easing just 0.2% from July's all-time high, with rent remaining 7% above where it stood a year ago , and Brooklyn's median rent pushed to a new record of $4,368 — indicating continued high, record-level NYC rents into fall 2026, though this uses Corcoran's own methodology, not StreetEasy's. - [2026-09-10] A Jonathan Miller/Real Deal report for August 2026 (also non-StreetEasy) found Manhattan median rent increased 6.5 percent to $4,900 compared to August 2025 , confirming the broader market trend of elevated, still-rising rents into late summer 2026, albeit via a different measurement than StreetEasy's. - [2026-01-15 context] StreetEasy itself had forecast in its 2026 predictions that rent growth would likely accelerate in New York City in 2026, following a 4.8% rise from January through October 2025, as the rental market tightens . (streeteasy.com/blog/2026-nyc-housing-market-predictions/) BOTTOM LINE: On StreetEasy's own series, the citywide median asking rent has run well above $3,800 all year — $3,950 in February 2026 and a record $4,199 in May 2026, up 7-8% YoY — and third-party trackers plus NYCEDC's use of the StreetEasy Rent Index indicate rents kept climbing through August 2026. StreetEasy has not yet published its own June–September 2026 citywide figure, but given the trajectory and typical seasonal patterns (prior-year November was already $3,875), a December 2026 StreetEasy citywide median asking rent above $3,800 looks highly likely absent an unusual seasonal collapse. NOT FOUND: StreetEasy's own published citywide median asking rent figures for June, July, August, September, or October 2026 (StreetEasy's blog "Market Reports" index shows no dedicated rental-market post for those months as of 2026-10-09); no StreetEasy data point for December of any prior year to directly benchmark seasonal December levels; no direct StreetEasy figure yet for December 2026 itself (not due until StreetEasy's regular report, typically published in the following month).
report: base rate
Base rate / outside view for StreetEasy's NYC citywide median asking rent exceeding $3,800 in a given December: - [2024-02] Looking back at December 2023, StreetEasy reported the median asking rent in New York City was $3,600 in December, 2.9% higher than a year ago but unchanged from November. (https://streeteasy.com/blog/brooklyn-queens-outshine-manhattan-as-key-nyc-rental-markets/) - [2025-12] For December 2025 (reported in the "Six Months In" FARE Act report), the citywide median asking rent was $3,875 in November, up 7.6% from a year ago — the comparable December figure a year ago, showing 2025 rents were already well above $3,800 heading into winter. (https://streeteasy.com/blog/fare-act-six-months-market-impacts/) - [2026-01/02] StreetEasy's neighborhood report (East Village) noted a 7.2% rise in median asking rent to $3,800 puts the neighborhood slightly above the citywide level around year-end 2025/early 2026, indicating the citywide figure itself was near or just under $3,800 at that point. (https://streeteasy.com/blog/10-nyc-neighborhoods-to-watch-in-2026/) - [2026-04] By March 2026, the citywide median asking rent rose 8.0% year-over-year to $3,995 in March, as inventory fell 2.4% to 29,978 units. (https://streeteasy.com/blog/nyc-sales-market-warms-up-despite-mortgage-rate-increases/) - [2026-06] By May 2026, the citywide median asking rent rose 7.3% year-over-year to $4,199 in May, a new high since StreetEasy began tracking the data in 2010. Manhattan reached a new StreetEasy high, with the borough's median asking rent up 7.2% year-over-year to $4,927, while Brooklyn also hit a record, rising 6.7% to $3,895. (https://streeteasy.com/blog/nyc-rental-market-update-one-year-after-fare-act/) - [2026-01/02] StreetEasy's own 2026 forecast anticipated continued acceleration: While Zillow predicts cooling rent growth in the national market, in New York City, rent growth will likely accelerate next year… As the rental market tightens, rents are on track to rise faster in 2026. (https://streeteasy.com/blog/2026-nyc-housing-market-predictions/) - [2026-08] Independent market summaries describe the trajectory through mid-2026: Citywide, the median asking rent has climbed into the low-to-mid $4,000s per month, up roughly 7–8% year-over-year, after breaking StreetEasy's all-time high in the spring. (https://www.skybriz.com/insights/average-rent-in-nyc-in/) - Seasonality base rate: an independent NYC rent-calendar tracker states December is typically the least competitive month to rent in NYC, followed by January and November. During winter months, there are fewer renters searching, giving you more time and leverage to negotiate. Renters can save 5-10% compared to peak summer months through reduced competition and occasional concessions. December is also flagged as the single cheapest month with roughly a 4% dip versus the annual average. (https://streetsmart.inc/ny/tools/rent-calendar) - Historical pattern (StreetEasy data, outside view): December citywide figures have tracked close to, and increasingly above, the November level each year as the 2023→2025 YoY growth rate accelerated from ~3% (Dec 2023) to ~7-8% (through 2026), meaning each successive December has cleared a higher threshold than the year before. - Track record of forecasters: StreetEasy's own economists correctly predicted accelerating 2026 rent growth (made in Dec 2025), a call that has been validated by realized data through at least May 2026 (new all-time highs each spring month). BOTTOM LINE: The outside view strongly favors YES: StreetEasy's citywide median asking rent has posted 7-8% YoY growth every month in 2026 on record, reaching $3,995 (March) and $4,199 (May), and even applying the typical ~4-10% seasonal December discount off a summer/fall peak in the $4,000-4,300 range would still likely land above $3,800; last December (2025) itself appears to have been already close to or at $3,800, and 2026 growth has been faster, not slower. NOT FOUND: An exact, confirmed StreetEasy citywide figure for December 2025 (precise dollar value) and for the most recent month, September/October 2026, were not located in a primary StreetEasy report during this search; only proxy/secondary sources (OpenIgloo net-effective rent, Apartments.com) were found for September 2026, which use different methodologies than StreetEasy's asking-rent median.
report: yes case
YES means: StreetEasy's official NYC citywide median asking rent figure for December 2026 (as reported on StreetEasy's own rentals/market-reports page) comes in above $3,800. - [2026-09-01] StreetEasy's own Market Reports index confirms the blog has published no dedicated citywide rental report since the June 11, 2026 post (May data); the only market-report posts since then — "More than half of families with children in NYC are rent-burdened" and "NYC homes selling above asking at highest rate in four years" — are rent-burden/sales pieces, not citywide median-rent updates, so the street-level May figure of $4,199 remains StreetEasy's last official data point. (https://streeteasy.com/blog/nyc-housing-market-data/market-reports/) - [2026-01] StreetEasy's own December-2023 historical data point shows the citywide median asking rent was $3,600 in December and was "unchanged from November," establishing that December typically tracks the November level rather than falling sharply — a seasonal pattern that, applied to 2026's much higher November base, supports a December figure well above $3,800. (https://streeteasy.com/blog/brooklyn-queens-outshine-manhattan-as-key-nyc-rental-markets/) - [2026-01] In the same historical period, StreetEasy reported that "in December, the median asking rent in Brooklyn and Queens was $3,395 and $3,000, respectively, significantly lower than $4,300 in Manhattan," showing Manhattan's December level already far exceeded $3,800 even in that earlier, cooler-rent year. (https://streeteasy.com/blog/brooklyn-queens-outshine-manhattan-as-key-nyc-rental-markets/) - [2026-01] StreetEasy's FARE Act six-month report noted that without the FARE Act's modest effect, "the average asking rent would have been $3,948, 11% higher than the current average," underscoring that even hypothetical downward adjustments to the current rent baseline keep the market comfortably above $3,800. (https://streeteasy.com/blog/fare-act-six-months-market-impacts/) - [2026-08-14] An independent synthesis citing StreetEasy data states that compared with 2025, "the citywide median asking rent is up roughly 7–8% year-over-year — a faster pace than 2024, and one StreetEasy expects to continue given low vacancy," indicating no deceleration signal through late summer 2026. (https://www.skybriz.com/insights/average-rent-in-nyc-in/) - [2026-10-08] A third-party tracker aggregating StreetEasy and other listing sources finds "the citywide median one-bedroom rent in NYC is $3,995 per month" as of October 2026, a different cut (1BR only) but directionally consistent with an overall median still well north of $3,800 heading into the final months of the year. (https://leaseswap.nyc/rent) - [2025-09-16] Corcoran's "Inhabit" series (non-StreetEasy methodology) reported Manhattan rents still at or near record highs through 2025-2026, and a 2026-09-08 update found Brooklyn's median rent reaching a new record of $4,368 — both boroughs' strength would need to reverse sharply for the citywide StreetEasy figure to fall under $3,800 by December. (https://inhabit.corcoran.com/) - [2026-01-15] StreetEasy's own 2026 forecast explicitly stated rents were "on track to rise faster in 2026" than the prior year's 4.8% pace, a call that has been validated by StreetEasy's own realized data through May 2026 (record highs each month), reinforcing the credibility of continued above-$3,800 readings into year-end. (https://streeteasy.com/blog/2026-nyc-housing-market-predictions/) - [2026-09] NYCEDC's Economic Snapshot (drawing on StreetEasy's Rent Index) found residential asking rents still rising for a seventh consecutive month through August 2026, with inventory down 14%, a tight-supply dynamic that structurally supports high asking rents persisting into December. (edc.nyc PDF, cited in prior research) BOTTOM LINE: The single most likely path to YES is simple continuation of the status quo: StreetEasy's own series has not shown a single month below $3,800 in 2026 (February $3,950, March $3,995, May $4,199), third-party and NYCEDC data confirm rents kept climbing through at least August, and StreetEasy's historical December pattern shows December typically holds near, not far below, the November level — meaning December 2026 would need an unprecedented multi-hundred-dollar seasonal collapse to drop below $3,800. NOT FOUND: StreetEasy's own published citywide median asking rent for June, July, August, September, or October 2026 (no monthly rental report has been published since June 11, 2026, covering May data); no official StreetEasy December 2025 citywide dollar figure to benchmark last year's December level precisely.
report: no case
YES means: StreetEasy publishes a NYC citywide median asking rent figure for December 2026 that is above $3,800 (the real-world outcome needed for the "Yes" resolution is actually rent staying elevated; the dimension assigned here argues the NO case — that the December 2026 StreetEasy figure comes in at or below $3,800). - [2026-09-01, data for Apr 2024 republished] StreetEasy's own history shows a prior cycle where citywide median asking rent growth collapsed from a spring peak: in April 2024 the asking rent rose just 1.7% YoY to $3,700, and the piece noted "Although rents are rising, the current annual growth rate is much slower compared to 14% a year ago." This demonstrates growth rates can decelerate by double-digit percentage points within a single year. - [~2024-01, reporting Nov 2023 data] In a prior fall, StreetEasy reported the median asking rent in New York City fell 2.8% to $3,500 in November from $3,600 in October, with the current median rent of $3,500 up just 2.9% from November 2022 — the slowest year-over-year rent growth since August 2021 . Separately that YoY rate had cratered from 17.3% a year earlier, per "a notable slowdown from the 17.3% year-over-year growth seen in November 2022." This is a concrete precedent for a rapid deceleration cycle hitting just before winter. - [~2025-01, reporting Aug 2024 data] In a more recent analog, StreetEasy reported "The median asking rent in NYC was $3,800 in August, just $20 higher than a year ago and $30 lower than July" , with the piece noting "The increase in rentals on the market, coupled with concessions, suggests competition among renters will continue to slow this year and next relative to recent years." This shows the $3,800 citywide level has historically been a point where growth stalled almost completely (+$20 YoY), not a level comfortably cleared. - [2024/legacy] StreetEasy's own methodology page warns the headline "median asking rent" metric is inherently volatile due to shifting listing composition: "The median asking rent can produce surprising results, however. For example, Manhattan's median asking rent in 2014 was $3,141, but in 2015 the median is $3,092 – a decline of about 1.6 percent. Reliance on the median asking rent would lead us to believe that rent prices are dropping in Manhattan, contrary to broad public perception." A compositional shift toward smaller/cheaper units entering the market in December (a seasonally thin, bargain-prone month) could mechanically drag the median below $3,800 even without "true" rent declines. - [2026-10 report, data for Sept 2026] OpenIgloo's independent September 2026 NYC rental report — a non-StreetEasy source but using recent live listings data — found "The citywide median net rent in September 2026 listings was $4,673 — down 3.6% from August 2026 and down 3.9% from September 2025" , with "The Bronx had the highest increases at +17.5%, while Queens saw a decrease of -6.4%" . While this uses a different (net effective, not StreetEasy asking) methodology and a different price level, the month-over-month and year-over-year declines are a signal the broader fall 2026 rental market may be cooling or reversing rather than extending the spring's acceleration. - [2026-01, forward-looking risk flagged by StreetEasy itself] StreetEasy's own 2026 outlook conceded a downside scenario: "private sector job growth has been slowing in NYC, leading to increased concerns over near-term job security... the NYC rental market outlook depends on broader economic conditions. While unlikely, if a national recession were to occur, rental demand could weaken sharply, mostly as renters generally have lower income and savings than homeowners, making them more vulnerable to a sudden loss of employment." Any labor-market softening into Q4 2026 could suppress demand ahead of December. - [2024-05, structural precedent] A 2024 report tied a Manhattan rent "leveling off" directly to white-collar layoffs: "Rents soared in Brooklyn and Queens due to limited inventory and high demand, while the median asking rent in Manhattan is leveling off as inventory grows and demand cools." The same report attributed this to "Rising inventory across the city likely signals a calmer rental market this year, though NYC still faces a severe housing shortage." If office-sector hiring softens again in late 2026 as it did in 2024, a similar leveling-off in Manhattan (the highest-dollar borough driving the citywide median) could pull the citywide figure down toward/below $3,800. - [2026-10-09, data gap] StreetEasy has not published its own citywide median asking rent figure for June, July, August, or September 2026 as of today, per the blog's "Market Reports" index — meaning the most recent confirmed StreetEasy data point remains May 2026's $4,199, and there is no verified StreetEasy evidence that growth continued uninterrupted through the summer and into fall. A reversal consistent with the OpenIgloo September reading would not yet be visible in StreetEasy's own public reporting. - [arithmetic] For December 2026 to land at or below $3,800, StreetEasy's citywide median would need to fall roughly 9.5% from May's $4,199 record — a magnitude smaller than the swing StreetEasy itself documented from November 2022 to November 2023 (YoY growth falling from 17.3% to 1.2%), showing such a correction is not without precedent even if it hasn't yet materialized in 2026's confirmed data. BOTTOM LINE: The NO case rests on precedent, not current confirmed data: StreetEasy's own history shows the citywide median asking rent has stalled or fallen outright in past falls/winters (Nov 2023 MoM decline, Aug 2024 flat YoY at exactly $3,800), the headline metric is explicitly volatile/compositional by StreetEasy's own methodology, and one independent September 2026 tracker (OpenIgloo, different methodology) shows a MoM and YoY decline that could foreshadow a StreetEasy slowdown not yet reported; still, no confirmed StreetEasy data point since May 2026 shows any such reversal, so this case rests on analogy and a data gap rather than direct evidence. NOT FOUND: StreetEasy's own June–September 2026 citywide median asking rent figures (not yet published); any explicit StreetEasy commentary on a 2026 autumn slowdown; a StreetEasy-reported December figure for any prior year below $3,600 to anchor a seasonal "floor."

(0) The condition is not yet met. December 2026 data will not be published until about mid-January 2027, and the StreetEasy dashboard returned a 403, so the latest confirmed StreetEasy figure is May 2026 at $4,199. (a) About 2.5 months of market time remain before the December reading, and the market closes 2027-01-31. (b) Status quo strongly favors Yes. StreetEasy's citywide median has been above $3,800 every reported month of 2026 ($3,950 in February, $3,995 in March, $4,199 in May), YoY growth has run 7–8%, and November 2025 was already $3,875. A 7% YoY gain on a December 2025 base near $3,800–3,875 implies roughly $4,050–4,150. The NYCEDC snapshot citing the StreetEasy Rent Index shows asking rents still rising through August, and Corcoran and Miller report record Manhattan and Brooklyn rents. (c) No path: a sharp fall slowdown (OpenIgloo shows a 3.6% MoM drop in September, though it uses a different methodology), plus the normal December seasonal trough and a compositional shift toward cheaper listings. Together these would have to push the median down more than 9.5% from the May peak, larger than the usual peak-to-winter seasonal decline. (d) Yes path: a normal seasonal dip of 4–8% off a summer peak near or above $4,200 leaves December around $3,950–4,100. The Kalshi anchor is 91–93% after slipping from 97%, possibly reflecting the softer fall signals. I see no specific unpriced information to move far, so I hold about 0.92 and keep some weight on the data gap since May and on metric or composition volatility.

(0) The condition is not yet met. The December 2026 figure will only be published by StreetEasy around January 2027, and the resolution-source fetch failed (HTTP 403), so I am relying on StreetEasy figures quoted in the research. (a) About 3.5 months remain until the December data month ends; resolution follows StreetEasy's release before the January 31, 2027 close. (b) Status quo strongly favors Yes. StreetEasy's citywide median was $3,875 in November 2025, $3,950 in February 2026, $3,995 in March and a record $4,199 in May, running 7–8% higher year over year. NYCEDC's read of the StreetEasy Rent Index shows rents still rising through August. A December 2026 figure near December 2025 (roughly $3,850–3,900) plus even modest growth lands around $3,950–4,100. (c) No would require a sharp autumn reversal: a recession or job-loss shock, or a compositional swing toward cheaper listings, producing a roughly 9–10% drop from the May peak and a year-over-year decline. Precedents include the 2023 deceleration and the OpenIgloo September 2026 reading of -3.6% month over month (different methodology), plus small risks of StreetEasy revising its data or changing methodology. (d) Yes needs only a normal seasonal dip of about 4–6% from a summer peak likely above $4,200, which keeps December around $4,000. The Kalshi anchor is 91% last trade (93/94 bid/ask), down from 97%. I see no specific new StreetEasy evidence of a slowdown that would justify going below the market, nor enough to go far above it given the unpublished June–September StreetEasy data.

The resolving condition is not already met: December 2026 remains ahead, with approximately 83 days until month-end and 114 days until the January 31 trading close, by which time StreetEasy's December observation would normally be available. Resolution requires its NYC → Rentals → Median asking rent to exceed $3,800; earlier threshold crossings, lease rents and rent indexes do not qualify. I anchor on Kalshi's supplied 91% Yes price, noting its higher 93–94% bid/ask, and trim one point for potentially underpriced September cooling reported by OpenIgloo in October, while recognizing that its net-rent metric differs. StreetEasy's June 11 report puts May's median at $4,199, so an unchanged level produces Yes, while reaching $3,800 requires approximately a 9.5% decline. A Yes scenario is modest winter easing against persistent supply constraints, with NYCEDC's September snapshot and August borough reports providing directional support for elevated rents. A No scenario combines weaker demand, winter seasonality and a cheaper December listing mix, bringing the published median to $3,800 or below. Historical slowing in annual rent growth does not establish a comparable price-level decline, and the supplied December history is too incomplete and internally inconsistent to justify near-certainty. The direct StreetEasy read failed with HTTP 403, and missing blog reports do not establish missing dashboard updates, so the 10% No allowance incorporates meaningful current-baseline, listing-composition and source-reporting uncertainty rather than assuming the May figure still describes today's market.

The condition is neither already met nor impossible: December 2026 is still ahead, and the direct StreetEasy resolution-source read failed with HTTP 403. There are approximately 83 days until December ends and 114 days until the January 31 trading close; the required observation is StreetEasy's December NYC median asking rent strictly above $3,800. I retain Kalshi's reported 91% Yes anchor, while noting its higher 93–94% bid/ask, because the research provides no verified recent observation of the exact resolving series that warrants overriding consensus. The latest exact-series figure found in the research is $4,199 for May, reported by StreetEasy on June 11, so holding that level would produce Yes, although it is not a verified October baseline. A YES scenario is continued rental-market tightness with winter easing of less than approximately 9.5% from May; NYCEDC's reported rise in the StreetEasy Rent Index through August supports this direction without establishing the median itself. A NO scenario is a December median at or below $3,800 following weaker demand, seasonal declines or a cheaper listing mix, with OpenIgloo's reported 3.6% September monthly decline offering limited corroboration because it measures a different, net-rent series. Dashboard-access gaps, publication timing and listing composition remain material uncertainties: missing rental blog posts do not establish that dashboard observations are unavailable, and neither CPI nor borough-level lease rents determine resolution. I also discount the reports' unsupported generalizations about December seasonality and their comparison of slowing annual growth with outright rent declines, leaving a meaningful downside tail rather than near-certainty.

(0) The resolving condition has not yet been met: StreetEasy has not reported December 2026, and its latest verified figure is May’s $4,199, so the December citywide median asking rent must still be published above $3,800. (a) About 12 weeks remain until December ends, with publication expected before the January 31, 2027 market close. (b) If current conditions persist, YES is the status quo: StreetEasy recorded $3,950 in February and $4,199 in May, while NYCEDC reported the StreetEasy Rent Index rising through August alongside a 14% inventory decline. (c) NO could result from a sharp winter slowdown, labor-market weakness, or a compositional shift in listings producing a decline of roughly 9.5% or more from May’s record to $3,800 or below; OpenIgloo’s September declines offer limited support but use a different metric. (d) YES requires only that elevated rents broadly persist through December, consistent with 7–8% year-over-year StreetEasy growth earlier in 2026 and third-party evidence of record-level rents through late summer. I anchor on Kalshi’s 91% YES price and move modestly to 93% because the continued StreetEasy-index growth through August and falling inventory strengthen the persistence case, while the missing recent StreetEasy dollar observations and failed direct resolution-source read prevent greater certainty.

Yes: 92% No: 8%
Mean of 5 draws (0.92, 0.93, 0.90, 0.91, 0.93). (0) The condition is not yet met. December 2026 data will not be published until about mid-January 2027, and the StreetEasy dashboard returned a 403, so the latest confirmed StreetEasy figure is May 2026 at $4,199. (a) About 2.5 months of market time remain before the December reading, and the market closes 2027-01-31. (b) Status quo strongly favors Yes. StreetEasy's citywide median has been above $3,800 every reported month of 2026 ($3,950 in February, $3,995 in March, $4,199 in May), YoY growth has run 7–8%, and November 2025 was already $3,875. A 7% YoY gain on a December 2025 base near $3,800–3,875 implies roughly $4,050–4,150. The NYCEDC snapshot citing the StreetEasy Rent Index shows asking rents still rising through August, and Corcoran and Miller report record Manhattan and Brooklyn rents. (c) No path: a sharp fall slowdown (OpenIgloo shows a 3.6% MoM drop in September, though it uses a different methodology), plus the normal December seasonal trough and a compositional shift toward cheaper listings. Together these would have to push the median down more than 9.5% from the May peak, larger than the usual peak-to-winter seasonal decline. (d) Yes path: a normal seasonal dip of 4–8% off a summer peak near or above $4,200 leaves December around $3,950–4,100. The Kalshi anchor is 91–93% after slipping from 97%, possibly reflecting the softer fall signals. I see no specific unpriced information to move far, so I hold about 0.92 and keep some weight on the data gap since May and on metric or composition volatility.
