Planner reasoning

This market resolves on the California count shown on Data Center Map's directory page, so the key tool is resolution_source, which gives the current count to compare against 305. kalshi_direct supplies the price anchor, and kalshi_related pulls the sibling strike markets in the same series to show the implied distribution. Polymarket very likely has no equivalent market, so I'm skipping it.

report: current state

- [2026-10-04] The resolution source, Data Center Map's official California directory page, currently displays "We currently have **296 data centers** listed, from 34 markets in California," which is below the 305 threshold. https://www.datacentermap.com/usa/california/ - [2026-10-04] The current breakdown on the same page shows Santa Clara (69), Los Angeles (59), San Jose (47), Sacramento (19), San Diego (15) and Irvine (14) as the largest markets, summing to 296 total listings. https://www.datacentermap.com/usa/california/ - [2026-10-04] A secondary tracker, Baxtel, separately reports "The California Data Center Market Has 306 data centers, operated by 105 providers," but this is a different dataset/methodology than Data Center Map and is not the resolution source. https://baxtel.com/data-center/california - [2026-09-ish] Another independent tracker (dcmap.us, "Data updated Aug 2026") reports California has 371 tracked facilities and projects, of which 305 are "operational" — again a different dataset from the contract's named resolution source and not directly comparable. https://dcmap.us/states/california/ - [2026-10-04] The USA-wide Data Center Map page (sister listing) corroborates the same California figure, showing California at 296 within a national total of "4767 data centers listed, from 50 states." https://www.datacentermap.com/usa/ - [2026-10-04] No news or press release was found indicating Data Center Map has recently added or is about to add a batch of new California listings; the 296 figure appears to be the current steady-state count on the live directory page. - [2026-10-04] Other trackers using different methodologies show a wide range of counts for California (e.g., Compute Atlas 83, usdatamap.com 67, Mapscaping 111, datacenters.com 494), underscoring that Data Center Map's own count (296) — the one specified in the resolution rules — is the only figure that matters here. https://www.compute-atlas.com/states/california, https://usdatamap.com/state/CA, https://mapscaping.com/california-data-centers/, https://www.datacenters.com/locations/united-states/california BOTTOM LINE: As of today the official Data Center Map California page — the exact resolution source for this contract — lists 296 data centers, 9 short of the 305 threshold, and there is no evidence of an imminent large batch of new listings before the December 31, 2026 measurement time; reaching 305 would require Data Center Map to add roughly 3% more listings to its California directory within the next ~3 months. NOT FOUND: No historical month-by-month growth trend for the Data Center Map California listing count (to gauge typical pace of new additions), no official announcement from Data Center Map about planned data updates or methodology changes before December 2026, and no indication of the count's value in recent prior months (e.g., Jan–Sep 2026) to establish a trend line.

report: base rate

- [2026-10-04] The resolution source, Data Center Map's official California directory page, currently shows we currently have 296 data centers listed, from 34 markets in California — https://www.datacentermap.com/usa/california/ - [2026-07-ish, "~207 days ago" snapshot] An earlier scrape of the same Data Center Map directory found a statewide directory listing shows 289 data centers in California across 33 markets , indicating the count rose by roughly 7 listings over the intervening months — https://brightlio.com/california-data-centers-brightlios-ultimate-guide-to-colocation-in-the-golden-state/ - [2026-07 methodology note] A secondary aggregator reports facility counts come from the Data Center Map database as of May 2026 , putting California at 287 at that time, consistent with slow, incremental growth of single digits per quarter rather than rapid jumps — https://usasymbol.com/rankings/infrastructure/data-centers-by-state - [Trend calc] Comparing the ~289 (spring 2026), ~287 (May 2026), and 296 (Oct 2026) snapshots implies Data Center Map's CA listing count has been growing at roughly 1–2 facilities per month over the past six-to-seven months, not in large discrete jumps, because the site adds confirmed/verified facilities individually rather than via bulk data refreshes — https://www.datacentermap.com/usa/california/ - [2026-09 (34 days old at fetch)] A separate, unrelated tracker — not the resolution source — reports a much larger universe: California has 371 tracked data center facilities and projects: 305 operational, 4 under construction, 46 planned, 0 paused, and 16 inactive or historical , but this is dcmap.us, a different, broader database (including planned/under-construction projects) with no bearing on what Data Center Map's own count shows — https://dcmap.us/states/california/ - [cross-check] Other independent counters of "California data centers" give wildly divergent totals (111, 114, 67, 83, 494, 287) depending on methodology, underscoring that no outside tracker is interchangeable with Data Center Map's own count, and only the datacentermap.com number is contractually relevant — https://mapscaping.com/california-data-centers/ , https://www.compute-atlas.com/states/california - [base-rate implication] Historically, Data Center Map's per-state counts move gradually as the site's team manually verifies and lists new operator facilities; there is no evidence of sudden bulk additions of 10+ facilities to California in a single quarter in the data gathered. - [extrapolation] Projecting the observed ~1–2/month net growth rate forward three months (Oct→Dec 2026) implies an end-of-year count in roughly the 299–302 range, below the 305 threshold, absent an unusual acceleration in Data Center Map's listing/verification pace. BOTTOM LINE: The outside view — based on Data Center Map's own recent trajectory (≈287–289 in spring 2026 rising to 296 by October 2026, a pace of roughly 1–2 new listings per month) — suggests the count would plausibly land just short of 305 by December 31, 2026 absent a marked acceleration in how quickly the site verifies and adds new facilities; other, much larger project-tracking databases (e.g., dcmap.us's 305 "operational" figure) are not the resolution source and should not be used to infer Data Center Map's count. NOT FOUND: An official, dated historical time series directly from datacentermap.com (e.g., monthly archived snapshots via Wayback Machine) could not be retrieved, so the growth-rate estimate relies on third-party citations of the Data Center Map figure at different dates rather than a verified first-party trend line; no public statement from Data Center Map itself about pending/upcoming additions to its California list was found.

report: yes case

YES means: the Data Center Map California directory page displays a count of at least 305 data centers at 11:59:59 PM ET on December 31, 2026. - [2026-10-04] The datacentermap.com Santa Clara market page itself states "CoreSite Santa Clara (SV6)... StratCap Wireless operates a purpose-built data center at 3205 Bassett Street in Santa Clara, California" among listings, and separately the page header text reads "Below you will find locations of 88 data centers in Santa Clara, California," versus the state-level summary table's figure of 69 for that same market — a 19-listing gap in one market alone, confirmed on a direct fetch of the page. - [2026-10-04] Similar gaps appear across other California market pages pulled via search: Los Angeles' market page reads "Below you will find locations of 73 data centers in Los Angeles, California" versus 59 in the state table (+14), and San Francisco's page reads "Below you will find locations of 15 data centers in San Francisco, California" versus 10 in the state table (+5), and Irvine, Sacramento and San Diego show similar size discrepancies of several listings each. - [2026-10-04] Summing just the market-page figures found in these fetched/search results (LA 73, Santa Clara 88, Irvine 14, Sacramento 22, San Diego 15, San Francisco 15, Fresno 3 = 230) against the same markets' state-table total (59+69+14+19+15+10+3 = 189) implies roughly 40+ "extra" already-indexed locations statewide that are not reflected in the site's own headline California count of 296 — a gap that, if reconciled by Data Center Map before year-end, would by itself push the displayed total well past 305. - [2026-04-13] A Pew Research Center analysis built directly on Data Center Map's underlying research database (not the public directory page) found California had California | 331 | 277 | 54 (total | operating | planned) as of "current as of Feb. 19, 2026" — meaning Data Center Map's own fuller dataset already counted 331 California entries eight months ago, well above 305, even though the live public page showed only ~287-289 at that time per other trackers' citations. - [2026-04-13] Pew's methodology explicitly used Data Center Map data and "combined data centers categorized as 'under construction,' 'planned' and 'land banked' into a single category and removed any projects marked as 'canceled' or 'uncertain'" , confirming Data Center Map itself maintains richer status-tagged records beyond the simple "listed" count shown on the directory homepage — raising the possibility that the publicly displayed California total could jump if DCM syncs its directory count to this broader internal dataset. - [2026-05-07] Concrete construction pipeline: Prime Data Centers "SACRAMENTO, CA. – May 7, 2026 Prime Data Centers... broke ground on SMF02, the second data center on its Sacramento campus. The 150,000-square-foot facility will deliver 18MW" , one of several concrete in-progress California projects (also STACK's Santa Clara SVY02A, reported in blackridgeresearch's list as "construction completed and is awaiting power from the local grid, Silicon Valley Power (SVP), as of November 2025" ) that are plausible candidates to flip to "operational" and be newly listed before December 31. - [2026-09-26] An independent California-focused capital tracker corroborates an active pipeline of named, physically real sites still being added to trackers, listing entries such as "Menlo Equities data center at Western Digital campus... San Jose, Santa Clara County | n.a. | 99 | proposed" and a Prologis North San Jose project with a special-use permit filed in late August 2026, indicating new Santa Clara-area facilities are still being identified and could be added to Data Center Map's listings before year-end. - [2026-09-ish] A separate, broader project tracker (dcmap.us) independently pegs California's "operational" count at exactly 305 as of its Aug 2026 update, per the figure already logged in the base-rate report — suggesting that under a plausible, defensible counting methodology the true number of operating California data center facilities may already be at or above the 305 threshold, and Data Center Map's public page (296) could simply be lagging in verifying/listing already-built facilities. BOTTOM LINE: The strongest YES path does not require a surge of brand-new construction; it rests on evidence that Data Center Map's own backend data (as reflected in its per-market listing pages and in the Pew Research Feb-2026 analysis of DCM's fuller dataset) already contains more California facilities than the "296" headline currently displayed, plus a live pipeline of near-complete projects (Sacramento SMF02, Santa Clara SVY02A, San Jose permits) — so if Data Center Map reconciles its directory count upward or lists even a handful of these near-complete projects as operational before December 31, 2026, the displayed total could cross 305. NOT FOUND: No official statement from Data Center Map explaining why its per-market page "locations" counts exceed the state-table "facilities" counts, nor any indication of when/whether it plans to reconcile these figures into the headline total; no confirmed date for when STACK SVY02A, Prime SMF02, or other near-complete projects will receive power/go operational and be added to the live directory.

report: no case

YES means: the Data Center Map California directory page displays a count of at least 305 data centers at 11:59:59 PM ET on December 31, 2026. - [2026-10-04] Data Center Map's own methodology page confirms listings are added mainly when operators self-register or are manually identified by staff, not via bulk automated ingestion: listings are driven by operators who "have direct access to add and update listings," by external sources that are "automatically queued for manual review," and by Data Center Map staff who "manually identify operators that we are missing and manually add them." This operator-driven, manually-reviewed process is structurally slow and gives no mechanism for a sudden jump of 9+ listings before year-end. - [2026-10-04] The same page states a minimum size threshold for inclusion — "To qualify for a listing, a data center needs to have at least 10 cabinets" — meaning small edge or enterprise sites opening in California would not even count toward the 305 threshold, further narrowing the pool of facilities that could push the total up in Q4. - [2026-10-04] Independent snapshot evidence (the ~289 figure cited in a scrape roughly 207 days before Oct 4, i.e. the spring 2026 period) corroborates the colleagues' trend read of slow, single-digit-per-quarter growth rather than any historical precedent of a 9-listing jump in a three-month window. - [2026-09-28] A dedicated moratorium tracker shows California enacted a sweeping anti-data-center legislative and local-regulatory wave in late September 2026: on September 21, 2026, Governor Newsom signed a seven-bill package (SB 1168, SB 886, SB 887, AB 1577, AB 2383, AB 2469, AB 2619) that directs "the CPUC to make data centers pay for the grid upgrades their load requires, creating a separate electricity rate class for them, and adding environmental review and water and land-use requirements." - [2026-09-28] The same tracker records that in the week of Sept 21–28 alone, California added its third municipal ban (Calexico) and extended an existing county moratorium (Tulare County, 10 months), part of a broader pattern where "restriction — not incentive — is now the default posture of local government toward new data center development" nationwide, with over 300 local bans/moratoria now adopted. - [2026-09-16] A separate California-specific moratorium tracker documents a dense cluster of new local restrictions clustered right at the start of Q4 2026 — Calexico's permanent citywide ban took effect late September/October, Brawley's moratorium runs to February 2027, Mendocino County's runs to mid-October, and Los Angeles County's planning department imposed an immediate prohibition on large AI data centers in unincorporated areas on September 18, 2026 — all suppressing new facility openings/filings in exactly the window (Oct–Dec 2026) that would need to generate new listings to hit 305. - [2026-09-18] The LA County action is corroborated on a second tracker: "The Los Angeles County Department of Regional Planning issued a memo on September 18, 2026 immediately prohibiting large-scale AI data centers in unincorporated areas while zoning amendments are codified," following an April motion by the Board of Supervisors. - [2026-07-ish] A litigation example shows even large, already-planned projects face delay: a developer of what would be the state's largest data center is fighting Imperial County's moratorium in court, with a July 28, 2026 hearing where the court pressed the county to identify the "irreparable harm" supporting its freeze — illustrating that pipeline facilities in California's most active growth corridor (Imperial County, a top-6 market in the Data Center Map breakdown) face active legal/regulatory friction rather than smooth progress toward opening and being listed. - [2026-10-04] Data Center Map's own disclosure that "there are no regulatory requirements to register data centers in a central database" and all databases rely on "voluntary data submissions," combined with the newly hostile California regulatory climate (operators facing new CEQA exposure, rate-class scrutiny, and local bans), gives operators less incentive to proactively self-list new, still-controversial California facilities before December 31. - [2026-10-04] No evidence was found of any Data Center Map announcement of a batch data refresh, API integration, or partnership that would mechanically inflate the California count; the directory's "cached for up to 24 hours" counts simply reflect organic accretion, per the official data page. BOTTOM LINE: With the resolution source sitting at 296 (9 short of 305), a documented organic growth pace of only ~1–2 listings/month driven by a slow operator-self-registration process with a 10-cabinet minimum, and an intensifying wave of California-specific legislative and local moratoria in September 2026 that disincentivizes and delays new facility openings/announcements in exactly the measurement quarter, the structural and regulatory evidence strongly favors the count remaining below 305 by December 31, 2026, supporting a NO resolution. NOT FOUND: No first-party, dated historical time-series directly from datacentermap.com (e.g., archived monthly snapshots) was retrievable; no evidence of Data Center Map issuing any statement about upcoming batch additions or methodology changes before the December 2026 measurement time; no data on how many "in queue" California operator submissions are currently pending manual review.

report: crux

CRUX: The decision-relevant fact is the actual, current Data Center Map (datacentermap.com) listed count for California and the recent net monthly growth rate of that listing, since the market needs the count to climb from its current level to ≥305 by Dec 31, 2026, 11:59:59 PM ET. - 2026-10-04 (today): The primary resolution source, datacentermap.com/usa/california/, directly fetched, states "We currently have 296 data centers listed, from 34 markets in California." This is corroborated by the USA-wide directory page showing California with 296 Data Centers listed among all states. - 2026-10-04: The state page breaks down the 296 total across 34 markets, with the largest concentrations in Santa Clara 69, Los Angeles 59, San Jose 47 and many smaller markets with 1-19 each — this is the exact figure the contract's "whole-number summary count" rule references. - The gap to the 305 threshold is therefore 9 net additional listed data centers in roughly 12 weeks (through Dec 31, 2026) on this specific directory's count. - Third-party/forecaster-cited historical reads (not independently verified by me via Wayback snapshots, which were inaccessible) suggest the same Data Center Map California count was roughly 287–289 in spring 2026, implying a net growth pace of only about 1–2 listings per month over the preceding several months to reach the current 296. - Other, non-resolution trackers show wildly different and non-comparable counts for California (e.g., Baxtel 306, datacenters.com 494, dcmap.us 371/305-operational, OpenStreetMap-derived mapscaping 111, compute-atlas 83, usdatamap 67), confirming that Data Center Map's own count is a distinct, manually curated figure that does not reconcile with other sources' larger totals — so "borrowing" numbers from city sub-pages or rival trackers would not mechanically raise the official state summary. - I found no evidence of Data Center Map announcing or having recently executed a batch reconciliation or methodology change that would suddenly inflate the California headline count; the 296 figure appears to be the product of incremental, manually-reviewed individual facility additions, consistent with the directory's typical slow cadence. - No dated historical snapshot of the exact California count (e.g., Jan/Feb/Jun 2026) could be independently verified by me this session (Wayback Machine fetch failed), so the "1–2/month" growth-rate claim rests on secondary citations rather than a first-party time series I directly confirmed. BOTTOM LINE: The only authoritative, directly-fetched figure is 296 as of 2026-10-04, 9 short of the 305 threshold, and the best available (though not fully first-party-verified) trend evidence points to a slow ~1–2 per month organic growth rate on this particular directory — a trajectory that would plausibly land in the 299–302 range by year-end, below threshold, favoring NO. The evidence does not support an imminent batch reconciliation that would close the gap, which is the main unresolved uncertainty behind the "YES" scenario. NOT FOUND: A verified first-party historical count (e.g., an archived Data Center Map California page from January, April, or July 2026) to confirm the exact monthly growth rate; any official statement from Data Center Map about planned backfilling, methodology changes, or batch updates to its California listings.

(0) Not resolved. The research directly fetched Data Center Map's California page and found 296 listed data centers on 2026-10-04, 9 short of the 305 threshold; the national directory page shows the same figure. My own resolution-source fetch failed with HTTP 429, so this rests on that one direct read. (a) About 12 weeks remain until the measurement time of Dec 31, 2026, 11:59:59 PM ET. (b) Status quo is NO. Secondary citations put the count at about 287–289 in spring 2026, so growth has been roughly 1–2 listings a month, which projects to about 299–302 by year-end. The site adds listings manually, with operator submissions and staff review, which suggests slow accretion rather than bulk refreshes. (c) NO: organic additions continue at their recent pace, and new California moratoria and the September legislative package add no tailwind. The count ends around 300. (d) YES: Data Center Map adds a multi-site operator in one go or does a backfill, possibly reconciling toward its larger per-market page counts (e.g., Santa Clara shows 88 on its page vs 69 in the state table). That would add 9+ listings in one quarter. The Kalshi anchor is 43% last trade, but the book is wide (35/64) on thin, 3-day history after falling from 75%. The documented trend needs roughly a tripling of pace, so I price below the market. I keep meaningful tail weight for batch additions, because the historical trend is secondhand and unverified.

(0) Not resolved. On 2026-10-04 the resolution source, Data Center Map's California page, shows 296 data centers, which is 9 short of 305, and the USA page confirms the same figure. (a) About 12 weeks remain until the December 31, 2026 11:59:59 PM ET measurement. (b) Status quo is No. Secondary citations of the same directory put it at ~289 in spring and ~287 in May 2026, implying net growth of roughly 1–2 listings a month. That pace projects to about 299–302 by year-end, short of 305. (c) No path: the directory keeps its slow, manually reviewed pace, and new California moratoria plus Newsom's September 21 data-center bill package further dampen new listings. (d) Yes path: a burst of operator self-registrations or a backend reconciliation adds 9+ listings. The per-market pages show higher location counts (Santa Clara 88 vs 69), though those likely reflect map radius rather than pending additions. Pew's analysis of the fuller Data Center Map dataset (331 including planned) hints at richer backend records. The Kalshi anchor is 43%, but the market is thin (3 days of data, 35/64 spread) and has already fallen 32 points. The first-party trend evidence argues for pricing below the midpoint. I keep meaningful tail weight because listing additions are lumpy and the historical trend is only secondhand.

The event is not resolved: despite the initial HTTP 429, subsequent research reads of Data Center Map’s California page and its USA directory both report 296 California listings as of October 4, below 305. Roughly 13 weeks remain until December 31, 2026 at 11:59:59 PM ET—not the January 7 trading close—and nine net additional listings are required; an unchanged count resolves No. I anchor on Kalshi’s 43% YES price, with its wide 35%–64% spread, and adjust modestly downward to 35% because the secondary Brightlio and usasymbol snapshots suggest growth of approximately 1–2 listings monthly, while recognizing their inconsistent dating and lack of verified historical archives. A straightforward NO scenario is continued gradual additions producing roughly 299–302 listings at measurement time. A YES scenario is accelerated operator submissions or a directory reconciliation adding at least nine net listings, supported as a possibility by Santa Clara’s reported city-page count of 88 versus 69 in the state table and Pew’s larger, status-inclusive Data Center Map dataset. However, those discrepancies could reflect classification differences rather than an update backlog, no reconciliation is announced, and only the California page’s whole-number summary at the measurement time governs settlement. I give limited weight to construction pipelines and reported moratoria because listings can concern existing facilities, while new construction or another tracker reaching 305 does not automatically change the resolving count. Confidence remains moderate because the current count is corroborated, but the historical growth rate, pending submissions, and explanation for the within-site discrepancies remain unverified, leaving substantial probability for an upward surprise.

I anchor on Kalshi’s 43% YES price (35% bid/64% ask), adjusting modestly downward because the research’s historical listing counts suggest slower growth than the nine net additions required, while treating that trend as uncertain. The condition is neither already met nor impossible: despite the initial HTTP 429 failure, subsequent reported direct reads show 296 on both Data Center Map’s California page and national index. Approximately 88 days remain until December 31, 2026, at 11:59:59 PM ET; the January 7 trading close does not extend this measurement deadline. If the displayed count remains unchanged, No wins. A plausible NO scenario is continuation of the estimated 1–2 monthly additions, producing roughly 299–302, although the historical figures cited by Brightlio and the May-2026-data aggregator are secondary, inconsistently dated, and lack independently verified archived snapshots. A plausible YES scenario is accelerated listing of existing facilities or an update incorporating some of the substantial city-page/state-summary discrepancies, without requiring nine newly constructed centers. However, Pew’s April analysis of Data Center Map’s broader dataset includes planned facilities, competing trackers use different definitions, and no announced reconciliation establishes that excess entries will reach the controlling state summary before measurement. I retain substantial YES probability for uncertain onboarding and update timing, while discounting claims that manual review prevents batches or that recent construction restrictions necessarily prevent listing existing facilities.

(0) The resolving condition has not been met: Data Center Map’s California page and its nationwide directory both showed 296 listings on October 4, nine below 305, so nine net additions must appear in the summary count by the measurement time. (a) Roughly 88 days remain until December 31, 2026 at 11:59:59 PM ET. (b) If the displayed count does not change, the market resolves No. (c) In the main No scenario, Data Center Map’s manually reviewed directory continues adding about 1–2 listings monthly, consistent with secondary snapshots around 287–289 in spring 2026, and finishes near 299–302. (d) Yes could result from faster organic additions or a batch reconciliation, particularly because city pages and Data Center Map-derived research suggest additional California facilities already exist in broader underlying records. Kalshi’s 43% Yes price is the anchor, but I move below it because the directly observed nine-listing gap, slow estimated growth, and absence of any announced reconciliation outweigh the speculative batch-update path; the market is also only three days old with a very wide 35%–64% spread. The principal uncertainty is that the growth history is based on third-party snapshots rather than a verified first-party time series, while Data Center Map’s inconsistent page counts leave meaningful tail risk of a sudden upward revision.

Yes: 28% No: 72%

Mean of 5 draws (0.20, 0.22, 0.35, 0.35, 0.30) after one crux research pass. (0) Not resolved. The research directly fetched Data Center Map's California page and found 296 listed data centers on 2026-10-04, 9 short of the 305 threshold; the national directory page shows the same figure. My own resolution-source fetch failed with HTTP 429, so this rests on that one direct read. (a) About 12 weeks remain until the measurement time of Dec 31, 2026, 11:59:59 PM ET. (b) Status quo is NO. Secondary citations put the count at about 287–289 in spring 2026, so growth has been roughly 1–2 listings a month, which projects to about 299–302 by year-end. The site adds listings manually, with operator submissions and staff review, which suggests slow accretion rather than bulk refreshes. (c) NO: organic additions continue at their recent pace, and new California moratoria and the September legislative package add no tailwind. The count ends around 300. (d) YES: Data Center Map adds a multi-site operator in one go or does a backfill, possibly reconciling toward its larger per-market page counts (e.g., Santa Clara shows 88 on its page vs 69 in the state table). That would add 9+ listings in one quarter. The Kalshi anchor is 43% last trade, but the book is wide (35/64) on thin, 3-day history after falling from 75%. The documented trend needs roughly a tripling of pace, so I price below the market. I keep meaningful tail weight for batch additions, because the historical trend is secondhand and unverified.
