final rationale
Mean of 5 draws (0.57, 0.55, 0.52, 0.52, 0.48). (0) Not resolved: Waymo's official 'Serving Riders In' list (direct fetch 2026-10-03) shows exactly 15 cities/regions, corroborated by trackers (Sept 24) and local press (Oct 2). That is inside but at the top edge of the 12-15 band, and must hold on the Dec 31 snapshot. (a) About 89 days remain. (b) Status quo of 15 resolves Yes; any single Up Next launch flips it to No. (c) No: Waymo keeps its fast 2026 cadence (10 to 15 metros Feb-Sept) and pushes toward its repeated 20+ cities by year-end goal. Philadelphia, Detroit or Seattle goes fully public in Q4, making 16. A smaller tail is a multi-city pause or invite-only treatment of gradual launches dropping the count below 12. (d) Yes: Q4 is consolidation (Nashville depot opening), and DC (2028), NYC (lapsed permit) and Chicago (no AV law) stay blocked. Seattle, Philadelphia and Detroit have no announced dates, so the count holds at 15. Market anchor is 51.85%. Sibling markets look inconsistent ('fewer than 12' at ~39% despite 15 live; '16-19' at ~5%), suggesting stale or thin pricing. My decomposition is ~35-40% chance of a new launch and ~4% of falling below 12, putting Yes modestly above the market.

report: current state
- [2026-09-01] Waymo opened paid, fully driverless public service in Denver, CO, San Diego, CA and Tampa, FL, taking it to 14 US metros . - [2026-09-14] Waymo publicly launched in Las Vegas, NV, becoming the 15th metro area to receive the autonomous ride-hailing service , with service starting along the Strip, Allegiant Stadium, Chinatown corridor, UNLV area and Spring Valley. - [2026-09-17] Waymo's San Antonio service, paused after severe flooding in April 2026, resumed on September 17, 2026, including trips to and from San Antonio International Airport, after software changes to detect standing water . - [2026-09-24] Per an independently verified robotaxi tracker, the US robotaxi leader — Waymo — operates 15 US metros, ~4,000 vehicles, ~500,000 paid public rides per week, ~4 million autonomous miles per week . - [2026-10-03] Waymo's own official "Updates" page lists exactly 15 cities under "Serving Riders In": Atlanta, Austin, Dallas, Denver, Houston, Las Vegas, Los Angeles, Miami, Nashville, Orlando, Phoenix, San Antonio, San Diego, San Francisco Bay Area, and Tampa (confirmed via direct fetch of waymo.com/updates/). - [2026-10-03] The same official page lists 17 additional cities under "Up Next" — Baltimore, Boston, Charlotte, Chicago, Detroit, Minneapolis, New Orleans, New York, Philadelphia, Pittsburgh, Portland, Sacramento, Seattle, St. Louis, Washington DC — plus London, UK and Tokyo, Japan — none of which are yet live. - [2026-09-14] Of the 15 live cities, Atlanta and Austin are accessed exclusively through the Uber app rather than Waymo One, per Waymo's own site labeling ("Ride on Uber"). - [2026-09-14] Las Vegas launch materials noted the rollout makes Las Vegas Waymo's 15th metro market and Nevada the eighth state to host the autonomous vehicle service . - [2026-09-14] Officials confirmed Waymo is ramping access gradually rather than opening fully: Waymo, a subsidiary of Google's parent company Alphabet, says it plans to steadily increase access to riders before opening service to everyone in Las Vegas. - [2026-08-20] Nevada regulators approved multiple AV operators (Waymo, Tesla, Uber's Aviari) to charge for rides in Las Vegas, a precondition that enabled the September 14 public launch. - [2026-09-24] None of the 17 "Up Next" cities (Detroit, Seattle, DC, NY, Boston, Chicago, Philadelphia, Pittsburgh, Baltimore, Charlotte, Minneapolis, New Orleans, St. Louis, Portland, Sacramento) nor London/Tokyo have begun public paid rides as of the tracker's last verification; these are announced intentions, not services, so none should be read as a launch date . BOTTOM LINE: As of October 3, 2026, Waymo's own official site and independent trackers agree it is live in exactly 15 cities (counting SF Bay Area and LA as single regions each), squarely inside the 12-15 range the market asks about; the question for year-end is whether any of the 17 "Up Next" markets (e.g., Seattle, Detroit, DC, NY, or international London/Tokyo) go fully public before Dec 31, which would push the count above 15, or whether any existing market is paused/pulled, which could push it below 12. NOT FOUND: No official Waymo statement with a specific launch date for any "Up Next" city (Detroit, Seattle, Washington DC, New York, Boston, Chicago, Philadelphia, Pittsburgh, Baltimore, Charlotte, Minneapolis, New Orleans, St. Louis, Portland, Sacramento, London, Tokyo) occurring before December 31, 2026; no evidence of any currently-live city being shut down or permanently suspended.
report: base rate
- [2026-02-24] Waymo publicly operated in 10 US metro areas (doubling from 6 months prior), after simultaneously adding Dallas, Houston, San Antonio and Orlando; CEO stated the goal was "laying the groundwork for service in 20+ cities" by end of 2026. https://www.techcrunch.com/2026/02/24/waymo-robotaxis-are-now-operating-in-10-us-cities/ - [2026-04-15] Miami and Orlando opened to the general public (more than 10 cities), consistent with a pattern of roughly one new public market every 3-6 weeks through the spring. Several cities moved through limited access into public availability at different times: Miami and Orlando: Waymo said more than 150,000 people joined the initial interest list before both markets opened to everyone on April 15, 2026. - [2026-07-08] Waymo launched fully driverless commercial rides simultaneously in four new cities (Denver, Las Vegas, San Diego, Tampa) in a single announcement, which outside commentary described as "a step-change acceleration of a rollout that had previously moved city by city over months, and brings Waymo meaningfully closer to its stated goal of more than one million weekly trips across 20-plus cities by the end of 2026." https://thetechmarketer.com/waymo-expansion-2026-new-cities/ - [2026-09-01] Denver, San Diego and Tampa opened to public riders, bringing the public network to 14 US metros; Las Vegas remained employee-only at that point. https://thechargeport.com/robotaxi-tracker - [2026-09-14] Las Vegas opened to paying public riders, which multiple outlets independently confirmed as Waymo's 15th metro market: Las Vegas marks the 15th metro area to receive the autonomous ride-hailing service, and the third to have majority Ojai fleets. https://news3lv.com/news/instagram/waymo-public-service-self-driving-cars-las-vegas-autonomous-vehicles-ride-hailing-robotaxi - [2026-09-14] Separately corroborated: The rollout makes Las Vegas Waymo's 15th metro market and Nevada the eighth state to host the autonomous vehicle service. https://www.fox5vegas.com/2026/09/14/waymo-launches-robotaxi-service-las-vegas/ - [2026-09-24] An independent tracker, cross-verified against Waymo's own "Serving Riders In" list, counted 15 live metros as of late September and listed 15 additional US cities (plus London and Tokyo) on Waymo's own "Up Next" roadmap, none with confirmed launch dates: Baltimore, Boston, Charlotte, Chicago, Detroit, Minneapolis, New Orleans, New York, Philadelphia, Pittsburgh, Portland, Sacramento, Seattle, St. Louis, Washington DC. https://thechargeport.com/robotaxi-tracker - [2026 (ongoing)] Waymo has reiterated the "20+ cities by end of 2026" target repeatedly since February 2026, a target that, if hit, would push the city count well above the 12-15 band; historically Waymo's own expansion announcements have tended to be optimistic on exact timing (cities announced for "2026" have sometimes taken many months from first manual-driving/testing to public launch), but the pace within 2026 itself has been unusually fast — roughly 9 new public cities added between February and September. - [Historical pattern] From 2020-2025, Waymo expanded far more slowly (Phoenix 2020, SF/LA 2024, Austin/Atlanta 2025 — about one new market every 6-12 months), making the 2026 cadence (8-9 new markets in under 8 months) a sharp break from the prior base rate and a sign the company has solved several earlier operational bottlenecks (fleet, charging, maintenance) that had previously limited scaling speed. NOT FOUND: No single authoritative, continuously updated public tracker giving a guaranteed final count for December 31, 2026; no confirmed public launch dates yet for Detroit, Washington D.C., Portland, Seattle, Chicago, or other "Up Next" cities that would determine whether the count rises above 15 before year-end. BOTTOM LINE: The reference class (Waymo's own 2026 rollout) shows an accelerating, not steady, cadence — the service moved from 10 to 15 public metros in about seven months (Feb–Sept 2026) — and the company has an explicit, repeated 20+ cities by end-2026 target with multiple additional cities already in advanced testing; this base rate of recent acceleration suggests real risk that the count moves past the 12-15 band by December 31, 2026, even though the count sits at 15 today.
report: yes case
YES means: Waymo's publicly available ride-hailing footprint (Waymo One app or partner platform) sits at 12, 13, 14 or 15 distinct cities/regions as of December 31, 2026, 11:59 PM ET. - [2026-07-19] Washington D.C.'s path to commercial driverless service is blocked by a DDOT-issued safety report years overdue, no driverless-testing permit pathway yet opened, and a council bill that even its own sponsor says likely means "nobody could actually get [it] done before Jan. 1, 2028." https://www.detroitnews.com/story/business/autos/2026/07/19/waymo-autonomous-vehicles-washington-dc/90976817007/ - [2026-06-11] As of mid-2026 Waymo and Zoox in D.C. were still testing with a human safety driver at the wheel, and the Bowser administration "hasn't issued" driverless-testing permits even as members of Congress pressed for action. https://www.axios.com/local/washington-dc/2026/06/11/waymo-dc-letter-house-republicans - [2026-04-08/2026-05-14] New York City's testing permit for Waymo's eight vehicles expired March 31, 2026 and was not renewed; state law still requires "a person holding a valid driver license... in the driver's seat," leaving "no current pathway to fully autonomous operation" in NYC. https://nyc.streetsblog.org/2026/04/08/waymo-testing-driverless-cars-gridlock-sam-autonomous-vehicles-safety ; http://www.centernyc.org/reports-briefs/2026/5/14/in-nyc-waymo-comes-to-a-stop-whats-ahead-for-driverless-cars - [2026 (undated, retrieved 2026-10-03)] Chicago remains in manual-mapping-only mode; Illinois has no AV legislation in place, Mayor Brandon Johnson's office says "there would be no autonomous operations deployed in Chicago," and robotaxitracker.com confirms "No robotaxi service is open to the public in Chicago, IL yet" as of its last update. https://robotaxitracker.com/cities/chicago - [2026-08-20/2026-08-25] Seattle remains listed only as "Up Next," with Waymo's own ride page still placing it there as of August 25, 2026, and local coverage confirming "Waymo has not published a Seattle launch date or public service map." https://www.seattleridesharelawyer.com/waymo-is-coming-to-seattle-what-riders-should-know-before-the-first-driverless-ride - [2025-11-18] Waymo's own November 2025 roadmap grouped Detroit, Las Vegas, Nashville, San Diego, Washington D.C. and London together as 2026 targets announced the same day — of these, D.C. and London are now the most likely to miss 2026, since D.C. faces multi-year regulatory gating and no international launch (London or Tokyo) has yet begun public paid rides. https://www.cnbc.com/2025/11/18/waymo-texas-florida-2026.html - [2026-10-02] Even among the 15 already-live metros, Waymo is still building out core infrastructure rather than racing to add new markets: a purpose-built Nashville depot with Lyft's Flexdrive only held its ribbon-cutting on October 1 and opens October 12, suggesting operational consolidation, not purely new-city sprint, is a current priority. https://wsmv.com/2026/10/02/hundreds-self-driving-cars-coming-nashville-with-new-waymo-lyft-facility - [2026-10-02] Local coverage independently reconfirmed the current count: "Nashville is one of 15 cities where Waymo is available," matching the official "Serving Riders In" list. https://wkrn.com/news/local-news/waymo-hub-nashville-flexdrive - [2026 (retrieved 2026-10-03)] No source found of any existing live city (Atlanta, Austin, Dallas, Denver, Houston, Las Vegas, LA, Miami, Nashville, Orlando, Phoenix, San Antonio, San Diego, SF Bay Area, Tampa) being paused or shut down since San Antonio's September 17 flood-related resumption, meaning the floor of the range (12) is not currently threatened from below. - [Mechanism] The single most plausible path to YES is simple continuity: none of the 17 announced "Up Next" markets — each carrying a distinct, unresolved legal/regulatory blocker (D.C.'s DDOT report and $6M+ permit fees targeting a 2028 effective date; NYC's expired permit and one-hand-on-wheel statute; Chicago's stalled Illinois AV bill and mayoral opposition; Seattle's undated "Up Next" status) — needs to clear its respective hurdle and launch publicly before December 31, 2026 for the count to stay at 15 or fall within 12-15; given each of these four largest "next" markets independently lacks a legal framework today, a multi-market simultaneous breakthrough in under three months is a high bar. BOTTOM LINE: The strongest case for YES rests on the fact that Waymo's three largest unlaunched "Up Next" markets — Washington D.C., New York City and Chicago — each face named, unresolved legal/regulatory blockers with no realistic 2026 fix (D.C. legislatively gated toward 2028, NYC's testing permit lapsed with no driverless pathway in state law, Chicago lacking any AV authorization), while Seattle (the most "ready" remaining market) still has no published launch date as of late August; absent a surprise regulatory breakthrough, the count is likely to stay at or near 15, within the 12-15 band. NOT FOUND: No confirmed public launch date for any "Up Next" city before December 31, 2026; no evidence that D.C., NYC, or Chicago's regulatory blockers have been resolved as of early October 2026; no reporting of any currently-live Waymo market being suspended or discontinued.
report: no case
YES means: Waymo's publicly-available ride-hailing service (Waymo One or an Uber partnership) operates in 12–15 distinct cities/regions as of December 31, 2026, 11:59 PM ET — i.e., the count stays within this band rather than falling to 11 or fewer, or rising to 16 or more. - [2026-10-03] Waymo's own site shows the count sitting at exactly 15 — the top edge of the 12-15 band — with 17 additional "Up Next" markets (15 US cities plus London and Tokyo) not yet live, meaning any single one of these crossing the finish line before year-end pushes the market to NO. - [2026-07-19] Reporting from Detroit News quotes a DC Councilmember saying the "best-case scenario" for a DC legal path is next spring, and that commercial deployment probably wouldn't begin until 2028, with the source saying "I would be hard-pressed to think anybody could actually get [it] done before Jan. 1, 2028." — ruling out one widely-watched upside risk, but underscoring how unpredictable the remaining "Up Next" timelines are. - [2026-08-20] A Seattle-focused report confirms that as of August 25, 2026 the company's ride page still places Seattle under "Up Next" rather than "Serving Riders In," and that Waymo has not yet announced the date public rides will begin, the boundaries of a Seattle service area, whether airport trips will be included at launch, or whether access will open to everyone at once — showing no fixed date that would resolve before Dec 31. - [2026-05-12] Philadelphia reporting (AOL/Fox29) states a potential launch "by end of 2026" is openly discussed, but as of that date the company operates in 11 other major cities and is working through the testing process with PennDOT and the Philadelphia Parking Authority to start commercial service , with no exact date fixed — Philadelphia going live in Q4 would be enough by itself to push the count to 16 and flip the market NO. - [2026-05-12] Local political resistance adds downside friction even for Philadelphia's relatively advanced pipeline: a city councilmember said "Waymo was invited to this joint committee hearing to come and explain itself to us and did not show up and because of that we are left with a lot of questions that are unanswered," illustrating that regulatory/political friction has repeatedly slipped Waymo's own timelines (DC, Philadelphia, Chicago all cite unresolved approvals). - [2026-02-25] Chicago expansion remains blocked on fundamentals: as of February 2026, the lack of regulatory approval for driverless rideshare will need to be resolved before we actually see driverless rideshare options in Chicago , with no update found that this has changed as of October 2026. - [2026-05-21 to 2026-05-23] Waymo has a demonstrated pattern of multi-city service pauses this year: a flooding-related defect led the company to halt operations in Atlanta, Austin, Dallas, Houston, and San Antonio simultaneously (per the 21 May pause), with Waymo having had three recalls since February 2024 and two active NHTSA investigations into separate failure modes ongoing — showing the live-city count is not monotonic and a severe-weather or regulatory event in Q4 2026 (hurricane season overlaps Tampa/Miami/Houston/New Orleans pipeline cities) could again force a multi-city pause that, if it coincides with Dec 31 and is judged non-trivial, risks dropping the "available" count below 15 or raising dispute about whether a paused city still "counts." - [2025-12-05] Separate from weather, Waymo has faced an active NHTSA probe and voluntary recall over illegally passing stopped school buses, with an Austin school district continuing to document incidents even after fixes — a reminder that safety-driven, abrupt regulatory or self-imposed pauses remain a live tail risk through year-end. - [2026-04-02 to 2026-04-10] Multiple Philadelphia-focused pieces as late as April 2026 state plainly that no official launch date has been announced, and PennDOT is working through the approval process — six months later, no subsequent source found confirming a date was ever set, consistent with Waymo's historical tendency to announce "expansion to city X in 2026" far ahead of actual public launch (DC was announced in March 2025 for "2026" and is now expected to slip to 2028). - [2026-09-24] The independent tracker cited by colleagues confirms that of 17 "Up Next" markets, none had begun public paid rides as of late September, meaning any NO-flipping launch must happen in a compressed ~14-week window (late Sept–Dec 31) — a tight runway given each prior launch (Denver, San Diego, Tampa, Las Vegas) took months from driverless-testing to public rides after safety-driver removal. BOTTOM LINE: The NO case rests on two levers: (1) real but politically/regulatorily contested "Up Next" cities (Philadelphia most advanced, then Seattle/Chicago) crossing into public service before Dec 31, which would push the count to 16+, and (2) Waymo's demonstrated 2026 history of abrupt, multi-city weather- or safety-driven pauses, which creates residual tail risk of a sub-12 count or a disputed "is it live" edge case right at the Dec 31 snapshot; DC is now effectively ruled out through 2026, narrowing but not eliminating the upside-breach pathway. NOT FOUND: No confirmed launch date for Philadelphia, Seattle, Chicago, Detroit, or any other "Up Next" city before December 31, 2026; no evidence of any current city being permanently shut down (only temporary weather/software pauses found); no official Waymo statement explicitly ruling out further launches before year-end.

(0) Not resolved: Waymo's official 'Serving Riders In' list (direct fetch 2026-10-03) shows exactly 15 cities/regions, corroborated by trackers (Sept 24) and local press (Oct 2). That is inside but at the top edge of the 12-15 band, and must hold on the Dec 31 snapshot. (a) About 89 days remain. (b) Status quo of 15 resolves Yes; any single Up Next launch flips it to No. (c) No: Waymo keeps its fast 2026 cadence (10 to 15 metros Feb-Sept) and pushes toward its repeated 20+ cities by year-end goal. Philadelphia, Detroit or Seattle goes fully public in Q4, making 16. A smaller tail is a multi-city pause or invite-only treatment of gradual launches dropping the count below 12. (d) Yes: Q4 is consolidation (Nashville depot opening), and DC (2028), NYC (lapsed permit) and Chicago (no AV law) stay blocked. Seattle, Philadelphia and Detroit have no announced dates, so the count holds at 15. Market anchor is 51.85%. Sibling markets look inconsistent ('fewer than 12' at ~39% despite 15 live; '16-19' at ~5%), suggesting stale or thin pricing. My decomposition is ~35-40% chance of a new launch and ~4% of falling below 12, putting Yes modestly above the market.

(0) Not settled: Waymo's official page lists exactly 15 live cities (Atlanta, Austin, Dallas, Denver, Houston, Las Vegas, LA, Miami, Nashville, Orlando, Phoenix, San Antonio, San Diego, SF Bay Area, Tampa), confirmed by local press on Oct 2, the top edge of the band. (a) About 13 weeks remain to the Dec 31 snapshot. (b) Status quo means 15, so Yes, which is why the market sits near 52%. (c) No: one of 17 'Up Next' cities (Philadelphia, Seattle, Detroit or Sacramento most plausible) goes fully public before year-end, driven by Waymo's repeated '20+ cities by end-2026' goal and its fast 2026 cadence of 10 to 15 metros in seven months. Alternatively the count falls below 12 under a strict 'invite-only' reading (Las Vegas is still ramping access) or through multi-city weather or safety pauses like May 2026. (d) Yes: no new city clears regulatory gates in the compressed Q4 window, DC, NYC and Chicago stay blocked, no launch dates are announced, and the list still shows 12-15 on Dec 31. Sibling markets price fewer than 12 at about 39% and 16-19 at about 5%, implying traders expect a stricter count. I think sub-12 is overpriced given the official list of 15, and 16+ is underpriced given the target, cadence and city markets such as Detroit at 12.5% and Chicago at 11%. Netting these gives roughly 25-35% for a new launch and about 10% for a sub-12 count, so I am slightly above the 0.52 anchor.

The event is not resolved: it measures availability specifically on December 31, 2026, at 11:59 PM ET, roughly 90 days away, rather than whether Waymo reaches this range beforehand. I retain Polymarket's live 51.85% YES anchor because the research identifies substantial competing risks but no sufficiently reliable, clearly underpriced launch catalyst. Waymo's official rides page currently lists 15 service regions, corroborated by September 24 tracking and October 2 Nashville coverage, so unchanged qualifying availability would resolve YES. However, September 14 Las Vegas reporting describes access expanding before opening to everyone; if access remains invite-only, that city must be excluded despite its official listing, potentially leaving room for another qualifying launch. The principal NO scenario is that all 15 qualify and one additional market, such as Philadelphia or Detroit, becomes publicly bookable before the deadline; sufficiently broad simultaneous service suspensions could instead push availability below 12. The YES scenario is continued operation within the existing footprint while additional launches remain testing or invitation-only, supported by documented regulatory obstacles in Washington DC, New York and Chicago and the absence of confirmed qualifying launch dates elsewhere. Those obstacles do not establish that all 17 upcoming markets are blocked, and September's clustered openings demonstrate that further expansion can occur quickly. I discount the research's stronger interpretation of the '20+' target because the cited wording includes 'laying the groundwork,' while conflicting launch chronologies and incomplete verification of unrestricted booking materially limit confidence.

I retain essentially Polymarket's 51.85% Yes anchor because the research does not establish a sufficiently reliable informational edge to justify a substantial adjustment. The event is not resolved: qualifying availability must hold on December 31, 2026, at 11:59 PM ET, approximately 13 weeks away. Waymo's official rides page currently lists 15 serving cities/regions, so unchanged, generally bookable service across that footprint would resolve Yes, including Uber-operated markets and counting the Bay Area as one region. However, September 14 Las Vegas reporting says access will expand before opening to everyone, leaving a material eligibility uncertainty: an invite-only rollout would not qualify merely because the official site labels it as serving riders. If all 15 qualify, the principal No scenario requires only one additional publicly accessible launch, while sufficiently broad year-end service suspensions could alternatively reduce the count below 12. The Yes scenario is that additional launches remain restricted or slip into 2027, supported by July reporting on Washington DC's regulatory delays, documented NYC and Chicago obstacles, and the absence of confirmed upcoming public-launch dates. Those obstacles do not cover all 17 pipeline markets, so the YES report overstates the protection afforded by blocking several prominent cities. Conversely, the reported target of laying groundwork in 20-plus cities is not equivalent to qualifying public service, and conflicting launch chronologies plus unresolved access classifications weaken the apparent expansion base rate and limit my confidence.

(0) The event is not already resolved: Waymo’s official rides page lists exactly 15 qualifying cities/regions as of October 3, but the required snapshot is December 31, 2026 at 11:59 PM ET. (a) About 89 days remain, during which Waymo would need either to launch another public service or suspend several existing services to change the current result. (b) If nothing changes, the count remains 15 and the market resolves Yes. (c) The clearest No scenario is one of the 17 “Up Next” markets—Philadelphia is specifically reported as targeting a possible end-2026 launch—opening to the public and raising the count to at least 16; a much less likely route is four or more concurrent service suspensions. (d) Yes results if no additional city becomes publicly bookable and at least 12 of the existing 15 remain available, supported by the absence of confirmed launch dates and substantial regulatory barriers in Washington, New York, and Chicago. Polymarket’s 51.85% Yes price is the anchor, but I move modestly below it because Waymo is already at the band’s upper boundary, has repeatedly targeted 20-plus cities by year-end, and needs only one of its broad pipeline of cities to launch. The lack of a dated next launch keeps this close to even, while potential lag or classification changes on Waymo’s official page add modest resolution-source uncertainty.

Yes: 53% No: 47%
Mean of 5 draws (0.57, 0.55, 0.52, 0.52, 0.48). (0) Not resolved: Waymo's official 'Serving Riders In' list (direct fetch 2026-10-03) shows exactly 15 cities/regions, corroborated by trackers (Sept 24) and local press (Oct 2). That is inside but at the top edge of the 12-15 band, and must hold on the Dec 31 snapshot. (a) About 89 days remain. (b) Status quo of 15 resolves Yes; any single Up Next launch flips it to No. (c) No: Waymo keeps its fast 2026 cadence (10 to 15 metros Feb-Sept) and pushes toward its repeated 20+ cities by year-end goal. Philadelphia, Detroit or Seattle goes fully public in Q4, making 16. A smaller tail is a multi-city pause or invite-only treatment of gradual launches dropping the count below 12. (d) Yes: Q4 is consolidation (Nashville depot opening), and DC (2028), NYC (lapsed permit) and Chicago (no AV law) stay blocked. Seattle, Philadelphia and Detroit have no announced dates, so the count holds at 15. Market anchor is 51.85%. Sibling markets look inconsistent ('fewer than 12' at ~39% despite 15 live; '16-19' at ~5%), suggesting stale or thin pricing. My decomposition is ~35-40% chance of a new launch and ~4% of falling below 12, putting Yes modestly above the market.
