Waymo's robotaxis started carrying members of the public in Denver, San Diego and Tampa on Tuesday, September 1, and the Kalshi board that asks where Waymo will operate before 2027 did what a board does when the news lands: it repriced the three cities everyone was already watching. San Diego went from a 51-cent bid to an 85-cent bid on more than 45,000 contracts in a day. Tampa went from 73 to 89. Denver, which had been sitting in the mid-80s for two weeks, traded roughly 100,000 contracts in a single session and showed a 99-cent last print by the Wednesday-morning pull.
None of that is the interesting part anymore. Four cities went fully driverless in Waymo's July 8 announcement, three of them opened to the public on September 1 while Las Vegas stayed "up next," and the market repriced Denver and Tampa the way a telegraphed launch gets repriced and San Diego like news. The interesting part is everything the board still has to decide, because the remaining half of this market has stopped being a bet on Waymo's engineering and turned into a bet on paperwork. Las Vegas is priced in the high 70s because Nevada's late-August approval started a 120-day launch clock. Sacramento sits near a coin flip because the California Public Utilities Commission approved the permit and Waymo will not say when it plans to use it. Detroit trades in the mid-20s to low 30s because the only date the company has offered is "driverless later this year," and that is not the same thing as public rides. Portland is priced by a state bill that failed, Seattle by a state bill that died in committee, Washington, D.C. by a council vote that has not happened, and London by a transport authority that has not said yes to anyone.
Here is the thesis of this page, and every section below tests it against one city: the forward half of the Waymo board is a regulatory calendar with prices on it. Read the calendar and you can read the board. The one I keep coming back to is Sacramento, because it is the city where a regulator had to say yes, did, and the price still has not made up its mind.
The Quick Answer
As of 4:44 a.m. ET on September 7, 2026, Kalshi's "Where will Waymo operate in 2026?" board prices the three cities that opened on September 1 at bids of 89 to 92 cents against asks of 95 to 97, and the four main unsettled cities at bids of 78 cents (Las Vegas), 44 cents (Sacramento), 25 cents (Detroit) and 5 cents (Portland). London is bid at 17 cents, Washington, D.C. at 6 and Seattle at 4, and the half of the board that had never traded a week ago has started to: Charlotte is bid at 45 cents on its first 700 contracts, and only five of the 21 cities remain untraded. Each city is its own yes-or-no contract, all of them can pay, and each one settles on whether paid, driverless, no-waitlist public rides exist inside that city before January 1, 2027. The full 21-city board, the regulatory clock behind each price, the fine print that keeps the launched trio below 99 cents, and what moved since September 3 are all below.

What September 1 Did To The Board
Start with what actually happened, because the contract cares about specifics. In a post on its own blog, Waymo said it would "begin welcoming our first public riders in Denver, San Diego, and Tampa" on September 1, "marking 14 cities where we're providing riders fully autonomous trips." TechCrunch reported the rides are paid and fully driverless, with Denver and San Diego getting the Zeekr-built Ojai minivan that carries Waymo's sixth-generation driving system, and it listed the 14: Phoenix, San Francisco, Los Angeles, Austin, Atlanta, Dallas, Houston, Miami, Nashville, Orlando, San Antonio, Denver, San Diego and Tampa. Electrek noted the three cities went "from waitlist to public in under two months," and Waymo said "tens of thousands in each city have already signed up."
The market's response is worth laying out city by city, because the shape of it tells you what traders believed going in. The doubt was San Diego. On the day before the launch its book was 51 cents bid against an 87-cent ask, a spread so wide it was barely a price, and its last trade had printed at 43 cents. On September 1 it traded 50 times for about 45,700 contracts, printing everywhere from 43 to 99 cents before settling into an 85-cent bid and 95-cent ask by Wednesday morning. Tampa was less contested, moving from 73 bid to 89 bid on about 24,000 contracts. Denver was the one the market already believed: it had been bid in the mid-80s since mid-August, and September 1 brought roughly 100,100 contracts through it in 36 trades, all between 90 and 99 cents. Denver now carries about 106,500 contracts of open interest, more than every other city on the board combined.
Here is the number that should stop you, though. None of the three is bid at 99, six days after the launch. Denver is 91 bid, 97 ask. San Diego is 89 bid, 95 ask. Tampa is 92 bid, 96 ask. Each has climbed three to five cents since the morning after launch, and for a service Waymo says is live, that still leaves a lot of doubt on the table, and the reason is written into the contract.
The clause that mattersa city only pays if the public can ride "without requiring special invitation codes, waitlist approval, or participation in testing programs." A launched city with a rolling invite list is live to a rider and unresolved to the contract.
Kalshi's rules for each city say the service "must be available to the general public without requiring special invitation codes, waitlist approval, or participation in testing programs," with paid rides and no safety driver at least some of the time, though a limited geofence is fine. Waymo's own launch post tells new riders to download the app, sign up, and "keep an eye on your email and notifications, we'll let you know as soon as it's your turn." Electrek described a rollout in which "customers will be admitted from waitlists over weeks." A city can have paying public riders on Tuesday and still be a rolling-invite service on paper, and a four-to-six-cent spread on a launched city is the market pricing exactly how long "your turn" takes to become "everyone's turn." That is not a knock on the launch. Consider it a reminder that this board settles on a definition, and the definition has a waitlist clause in it. Waymo's launch post says the company will "work toward opening our service to everyone," and each of the three contracts has until January 1 for that to be true.
The launched trio, in other words, is a bet on a calendar too, just a short one. The unsettled cities are the same bet with more uncertainty and better prices, and the first of them has a literal deadline.
Las Vegas: The One With A Deadline
The forward half's biggest number belongs to Las Vegas, which is not on Waymo's launched list. The contract is bid at 78 cents against an 83-cent ask, down from 82 bid on the morning of September 2, with about 3,600 contracts open and about 47 contracts traded in the last 24 hours. A price in the high 70s is the market saying "very likely, not done," and the reason it is not done is the same reason it is likely.
On August 20 the Nevada Transportation Authority approved applications from Waymo, Tesla and Aviari to operate as autonomous vehicle network companies in Clark County. Waymo's authorization covers up to 1,000 fully autonomous vehicles in its first 12 months, includes Harry Reid International Airport pending a separate sign-off from the county's aviation department, and comes with a condition that does most of the pricing work on this contract: operations must commence within 120 days of the permits being issued. Count 120 days from late August and you land in mid-December, inside the January 1 window with about two weeks to spare.
Waymo has been driving the Strip without anyone behind the wheel since July, when it began fully autonomous rides for its own employees and said it would open to the public "in the coming months." On August 13 it announced a partnership with the Las Vegas Raiders and Allegiant Stadium. Waymo's own city-status page still lists Las Vegas under "up next" rather than "serving riders," which is the whole gap between 78 cents and a dollar.
So what does a price in the high 70s actually reflect? A regulator with a deadline, a company already driving the roads empty of safety drivers, and a contract that pays if the public gets in before New Year's. What that price is exposed to is the same waitlist clause that is holding Denver at 91, plus one caveat the September 1 launches supply themselves: Las Vegas was in the same July 8 fully-driverless group as Denver, San Diego and Tampa, and it is the one that did not open with them. Eight weeks from driverless to public is the fast case, not a rule, and that gap is part of why the bid is 78 and not 95. The other part is that Waymo could open Las Vegas to invited riders in November and still be working through a signup list on December 31. In payout terms, an 83-cent contract turns $100 into about $120 if Las Vegas resolves yes, and nothing if it does not. The market has priced a launch that is close to certain and a definition that is not.
Sacramento is the opposite case. Its regulator has already said yes, and the price is nowhere near the 80s.
Sacramento: The Permit Arrived, The Date Didn't
Sacramento is bid at 44 cents against a 47-cent ask, with a last trade at 47, about 4,100 contracts open and about 570 traded in the last day, which still makes it the most active of the unsettled names by a wide margin. It was bid at 42 cents the day before the launches and 49 the morning after, so the September 1 news lifted it, and the five days since have given most of that back while the spread closed from 10 cents to 3. This is the coin flip in the title, and the reason it is a coin flip is that the two things a city needs are split down the middle here: the permission exists and the plan does not.
In mid-August the California Public Utilities Commission approved Waymo's request to extend its paid driverless service across a wide swath of Northern California, a decision Folsom Times reported covers Sacramento along with Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Santa Clara, Santa Cruz, Solano, Sonoma and Yolo counties, and San Diego in the south. CapRadio put it plainly on August 24: Waymo has the green light to hit Sacramento's streets. That is the box Las Vegas only checked on August 20, and Sacramento checked it first.
Then comes the half that is missing. Waymo's cars in Sacramento are still running with autonomous specialists inside them during testing, per Folsom Times, and when asked about a launch date the company said, "We do not have any updates on timing," adding that expansion "will be gradual and guided by our safety framework." Sacramento was announced in February, and San Diego, which Waymo named back in November 2025, rode the same CPUC approval to public service in about two weeks. That is the whole bear case: two cities cleared by the same regulator on the same day, and Waymo took the specialists out of the cars in one of them and not the other, which says the constraint is Waymo's own rollout queue rather than any government.
And the bull case is exactly the same fact read the other way. The three cities that just opened needed roughly eight weeks from "fully autonomous operations" to public riders, and Sacramento has four months left on the contract and no government left to persuade. If Waymo pulls the specialists out of the cars in September or October, the September 1 template says public rides can follow before the deadline. If it does not, there is no external clock forcing the issue, and that is the difference between this price and Las Vegas's. A 47-cent ask turns $100 into about $213 if Sacramento opens in time. The market is saying it does not know which of Waymo's two habits wins, the fast one or the quiet one, and I do not think anyone outside Waymo does either.
Detroit has the same two halves in a worse order: a driverless timeline the company keeps implying, and a permissive regulatory structure with no one agency holding a clock.
Detroit: Betting On Winter
Detroit is bid at 25 cents against a 32-cent ask, last trade 26, about 4,400 contracts open and just 6 traded in the past day. It nudged up from 27 bid to 29 on the launch news and has since slipped below where it started. Read the spread first, because a week ago it was the second-widest two-sided book on the board: 29 bid against 47, an 18-cent gap that meant the seller wanted nearly half a dollar for a contract the buyer valued at under a third. It has closed to 7 cents, and it closed from the top, the ask coming down 15 cents while the bid gave up 4. Nobody is confident here, but the side that was asking half a dollar has stopped.
The way that spread closed is the clue, and the record explains it: the public statements about Detroit are about driverless testing, never about public rides. Waymo named Detroit as its first Midwestern market in November 2025 and started on-road testing that week with trained specialists behind the wheel, pitching the launch as a proof point for winter-hardened sensors, the ones WXYZ reported come with heaters, wipers and cleaning fluid. Waymo's Jake Tretter told the station: "Over time, we will expand the number of vehicles in the fleet to hundreds of vehicles, but we start small." By late May, per Crain's Detroit Business reporting, the cars were still running with a specialist aboard, that Waymo planned to go fully driverless later this year, and that it had not said when public rides would be available. Crain's also noted the oversight vacuum: Michigan's autonomous vehicle framework is permissive enough that no single agency is fully in charge of how the cars integrate into city streets.
Put that against the two cities above and Detroit's price makes sense. Like Sacramento, there is no permit deadline on the record, so no clock. Unlike Las Vegas, nobody has handed Waymo a date to hit. What Detroit has is a company that keeps saying "this year" about driverless operations, not public rides, and a rollout template from September 1 that says public rides trail driverless operations by about two months. On the September 1 template, driverless in October gives Detroit a December public launch and a yes. Driverless in December does not, and the template itself has already been broken once, by Las Vegas. A 32-cent ask pays about $313 on $100 if Detroit opens in time, which is what roughly one chance in three costs; the 25-cent bid says one chance in four. On a 7-cent book those two numbers are close enough to call one price, and that price, discounted for the fact that every deadline slip runs into a Michigan winter, is the finding.
With those three cities in hand, the rest of the board reads quickly, so here is all of it.
The Board: All 21 Cities
Each row is a separate yes-or-no contract on whether Waymo is running paid, driverless, no-waitlist public rides inside that city before January 1, 2027. The contracts are independent, so the column does not add to anything. A bid is what someone will pay you for a yes right now; an ask is what a yes costs you. Where a row shows no last trade, nobody has ever bought or sold that city; the bid and ask on those rows are resting orders, not prices anyone has paid.

Live Kalshi order book for event KXWAYMOCITY-26DEC, pulled 4:44 a.m. ET on September 7, 2026. Volume and open interest are contract counts, not dollars. Five of the 21 rows have never traded, and each of those now carries a resting bid and ask; Chicago shows a 64-cent ask with no bid.
The row I want to narrate is Portland, because it is the clearest example on this board of how little a "last trade" can mean. At our September 2 pull, Portland's last print was 31 cents, a one-contract trade at 1 a.m. ET that morning, and it looked like a market that gave Waymo nearly one chance in three. But the bid underneath it was 9 cents, the ask was 32, and the previous 24 hours' activity was 66 contracts. On August 31 the book had been 2 bid, 12 ask. One buyer walking a thin book from 4 cents to 33 on the evening of launch day, on about 25 contracts, was not a reassessment of Oregon politics. It was a single order, and five days later the book has said so: the last print is 7 cents, the bid is 5 and the ask is 10, after about 210 contracts changed hands since that pull, most of them sellers. On a book like this, the bid and the ask are the price. The last trade is a rumor, and this one is gone.
The other thing the table shows is how closely Kalshi's list tracks Waymo's own. Waymo's city-status page lists 18 cities under "up next," from Baltimore to Tokyo, and every one of them is a row here; the three launched cities complete the 21. The one announced Waymo city the board does not carry is Munich, which the company announced on August 25 with public service targeted for late 2027, outside this contract's window. On September 2, 11 of those 18 "up next" cities had never traded a single contract, which told you the market had sorted Waymo's list into cities with a 2026 story and cities with a press release. That sorting got messier this week, which is the next section.
What Moved Since September 3
Against our September 2 pull, the launched trio kept climbing, on almost no volume. Tampa's bid went from 89 cents to 92, Denver's from 86 to 91 and San Diego's from 85 to 89, on roughly 330 contracts across all three since September 3, against the 170,000 or so that went through them on launch day. What little flow there was came from sellers hitting bids, every Denver and Tampa print among them, and the bids came back higher each time. Nobody needs to buy the launched cities; the bids are drifting toward the dollar at the pace of the invite list.
The forward four all slipped, and none of them had a headline. Las Vegas gave back its launch-week gain and more, from 82 bid to 78: the price history shows buyers lifting it to 85 and 86 cents on Saturday afternoon, September 5, then sellers walking it back down to 77 through Saturday night and Sunday morning, about 300 contracts in all, with nothing new out of Nevada in between. Sacramento traded about 1,460 contracts, the most on the board by a wide margin, and went from 49 bid to 44 while its ask fell from 59 to 47; sellers pushed it into the high 30s on Thursday afternoon, Saturday morning and Sunday evening, with one nine-contract print as low as 21 cents on Friday night, and buyers bought it back to 47 in the early hours of Monday. Detroit closed its 18-cent spread to 7, almost entirely from the ask side. Portland's early-week prints in the 30s were sold back down to 7. Waymo's own city page still lists all four under "up next," and the Nevada, California, Michigan and Oregon records are exactly where they were on September 2. Two of the single-digit cities went the other way. Washington, D.C.'s bid doubled from 3 cents to 6 on about 265 contracts, and London's rose from 7 cents to 17 on about 340, most of them a single 200-contract buy at 19 cents on the evening of September 2, with nothing new from Transport for London behind it.
The dormant half of the board woke up. Six cities that had never traded printed their first contracts: Charlotte (about 700), Boston (about 410), New York (about 315), Chicago (about 200), Pittsburgh (about 85) and New Orleans (39). Charlotte is the strange one. On the morning of September 3 a buyer took 200 contracts at 49 cents and 105 more at 93 in the same minute, sellers then hit the bids back down through 56, 55, 53 and 51, plus one 41-contract print at 27 that is still the row's last trade, and the book now sits at a 45-cent bid on a city Waymo lists under "up next" with no launch date and, as far as the public record shows, no news at all this week. The other five never-traded rows, Philadelphia, St. Louis, Minneapolis, Baltimore and Tokyo, now carry two-sided quotes between 17 and 38 cents, with five-contract bids against 200-contract asks. Those resting sizes are a snapshot of this morning's book, not a trend, but the same 200-contract size sits at the top of the book on a dozen rows, which reads like one participant quoting the whole board rather than a dozen separate opinions about a dozen cities. Treat the new mid-board prices the way this page treated Portland's 31-cent print: a bid is an order, not a verdict, until the record behind it changes.
Portland, Seattle, D.C. And London: Priced By A Vote Nobody Has Taken
The single-digit cities share one feature: the thing standing between Waymo and a paying rider is a government decision, not a vehicle.
Portland was announced as Waymo's next market on April 28, and the cars have been mapping the city with human drivers since. OPB reported that Oregon's House Bill 4085, which would have set statewide standards and explicitly allowed companies like Waymo to run fully driverless cars, did not pass in the 2026 session, and that a new bill is not expected until the legislature reconvenes in 2027. Portland's City Council public works committee spent the summer debating fleet caps, curb rules and per-mile fees, and aims to finalize rules in fall 2026, ahead of a 2027 state session. Councilor Mitch Green put the local mood on the record: "If we go down this road to permit Waymos to operate in our city, there will be a labor displacement problem. Like that's real." A contract that needs a state law that will not be reconsidered until 2027 is a contract about 2027. The 5-cent bid understands that; the 31-cent print did not, and it is gone.
Seattle has the same problem with a different bill number. Waymo's Ojai minivans have been spotted testing in Ballard and Bellevue, Fox 13 Seattle reported in August, and the station was blunt that "it is unclear when the Ojai vehicles will officially begin operating in Seattle." GeekWire has reported that Washington lawmakers still need to pass a dedicated framework before a company can pull the safety driver for paid rides, and that the bill meant to do it, SB 6243, died in committee in the 2026 session. Seattle's ask collapsed from 68 cents to 5 on September 1 on ten contracts, and that 5-cent offer turned out to be one seller. It was gone by September 3, when 79 contracts printed at 10 and 11 cents, two-thirds of them sellers hitting bids, and the book is now 4 bid, 12 ask. The 4-cent bid sitting on about 3,700 open contracts has been saying no for a while, and it did not move.
Washington, D.C. is the one where the vote might actually happen in the window. Councilmember Charles Allen's Autonomous Vehicle Deployment Authorization Amendment Act of 2026 would legalize commercial driverless service in the District; Fox 5 DC reported when it was unveiled in April that cars without a driver behind the wheel are not currently legal in D.C., which is why a year of Waymo testing there has not produced a ride. Local reporting says a final vote is possible this fall or winter, and Waymo, which has been pushing back on a proposed 200-vehicle cap, added a third D.C. facility in August while it waits, per Axios. Even a yes vote in November leaves Waymo weeks, not months, to go from legal to public. The 6-cent bid and 13-cent ask, on about 3,200 open contracts after roughly 265 traded this week, are a market that thinks the vote is live and the launch is not: a 7-cent spread on that much open interest is disagreement about a real event, not an empty room.
London is the international case, and it is a reminder that "Waymo said 2026" and "Waymo will resolve yes" are different sentences. TechCrunch reported in April that about 100 Jaguar I-PACEs had begun autonomous testing across roughly 100 square miles of the city with a safety operator behind the wheel, targeting a commercial launch in 2026 contingent on regulatory approval. By late August, TechTimes reported Waymo was still describing a "fully autonomous service by the end of this year" without committing to paid public rides in that window, and that a Transport for London response dated July 23 said the agency was still "developing its approach" to driverless consent requests, with no evidence any operator had one. London's book did something the thin rows did not on launch day: the bid rose from 3 cents to 7 while the ask fell from 25 to 19, a spread closing from both sides, which is a real repricing rather than a single print. It kept going: the bid is now 17 cents and the ask 24, after about 340 contracts this week, most of them one 200-contract buy at 19 cents on the evening of September 2. Nothing new has come out of Transport for London since the July 23 letter, so a 17-cent bid is a buyer's opinion about a launch that still requires three separate approvals nobody has been granted, and among the cities that were bid in single digits a week ago, it is the price that moved furthest from the record rather than toward it.
Tokyo, where Waymo has been testing since 2025, now sits with Philadelphia, St. Louis, Minneapolis and Baltimore as the five rows that have never traded, though each carries a resting quote. They are worth watching for one reason: this is a rebuild-in-place page, and if Waymo drops a surprise city announcement the way it did with Portland in April, the first sign will be a real trade in a row that has never printed one.
The Market Card
Kalshi lists this board as Where will Waymo operate in 2026? (event ticker KXWAYMOCITY-26DEC), filed under its science and technology markets, with Waymo's own announcements as the settlement source. Each of the 21 cities is a separate contract that resolves yes if Waymo "is operating commercial autonomous vehicle ride-hailing services available to the general public" within that city before January 1, 2027. The rules spell out what counts: the public can download the Waymo app or use a partner app such as Uber, request a ride with pickup and dropoff inside the city, and get a driverless ride for a fee, without an invite code, waitlist approval or a testing program. A limited geofence within the city is fine. Employee shuttles, closed testing, cars with a safety driver in every vehicle, a plan announced but not launched, and any service that still requires being on a waitlist all resolve no. Contracts close December 31, 2026, with settlement expected the following week.

The Bottom Line
The three cities that opened on September 1 were the easy half of this board, and they repriced like it: Denver, San Diego and Tampa are all bid between 89 and 92 cents, held short of a dollar only by a waitlist clause and the weeks it takes "your turn" to become everyone's. What is left is a regulatory calendar with prices attached. Las Vegas trades in the high 70s because Nevada gave Waymo a permit with a 120-day fuse. Sacramento trades in the mid-40s because California's utilities commission gave Waymo a permit with no fuse at all, and Waymo will not say when it lights one. Detroit trades in the mid-20s to low 30s because the only clock is the company's own phrase "later this year," and that phrase was about driverless testing, not riders. And Portland, Seattle and D.C. are bid in single digits because the clock there belongs to a legislature or a council, and two of the three legislatures have already gone home.
The callback that ties it together is the September 1 template itself: roughly eight weeks from pulling the safety driver to public riders, with Las Vegas standing as the reminder that eight weeks is the fast case and not a promise. Apply it to every remaining city and the board sorts itself. Anyone driverless by late October has a real path to a yes. Anyone still carrying a specialist on November 1 is mostly a 2027 story, whatever the last trade says. That is the test this page will run each time a city changes state, on this same URL, until the last contract settles in January.
