Tesla’s Robotaxi service is available in San Antonio from 5 a.m. on Monday, 9 November, Tesla’s official @robotaxi account posted on X: “Robotaxi available in San Antonio starting tomorrow, 5am”. Asked whether that meant today or the next day, the account replied “Monday”. The post shows a launch geofence around central San Antonio.
By our count of Tesla’s own @robotaxi posts, San Antonio is the ninth city the account has named for Robotaxi service and the fifth in Texas, after Austin, Dallas, Houston and Fort Worth. It is the first of four cities the account listed as “coming soon” on 21 October to open, 19 days later by our arithmetic.
Business Pill · Physical AI Explained
An evergreen Business Engineer explainer on physical AI: AI systems that act in the physical world, such as robots and self-driving vehicles. It explains the general idea only and does not discuss Tesla or any company in this piece.
The key insight:Tesla’s @robotaxi account said Robotaxi is available in San Antonio from 5 a.m. on Monday, 9 November. By our count of the account’s posts, that is the ninth city it has named for service and the fifth in Texas, and the first of four cities listed as coming soon on 21 October to open, 19 days later by our arithmetic.
The @robotaxi post went up at 06:27 UTC on 9 November with a map titled “San Antonio, TX” and a shaded “Launch geofence” covering central San Antonio, roughly inside the Loop 1604 highway ring as drawn. The X account of Sawyer Merritt relayed the launch, writing that rides begin on “November 9th at 5 AM CT”.
The posts we read do not state prices, the size of the San Antonio fleet, or whether a safety monitor rides in the vehicles there. Tesla described its service in the Austin metro area as “Unsupervised Robotaxi” in a 3 June post; it has not said the same about San Antonio in the posts we read.
Cities named for available Robotaxi service in Tesla’s @robotaxi posts on X, by post date, June 2025 to 9 November 2026. The count of nine, five in Texas, is ours.
What Was Posted on X
Robotaxi available in San Antonio starting tomorrow, 5am
Tesla’s official @robotaxi account posted on 9 November that Robotaxi is available in San Antonio starting at 5am, with a map of the launch geofence. Asked whether that meant that day, the account replied “Monday”. This post is the primary source for the launch in this piece.
Nine Cities in Tesla’s Own Posts
We read every original post on the @robotaxi account, 160 of them back to June 2025. The cities it names for available service, in order, start with Austin and the Bay Area (“Available all over Austin & the Bay Area”, 5 January 2026). Then come Dallas and Houston (“Robotaxi now rolling out in Dallas & Houston”, 18 April), Miami (3 July), Tampa and Orlando (21 July), Fort Worth (“Robotaxi available in Fort Worth starting tomorrow, 6am”, 2 November) and San Antonio. That is nine, five of them in Texas, by our count.
On 21 October the account listed “Robotaxi coming soon: Las Vegas, Nevada Jacksonville, Florida Phoenix, Arizona San Antonio, Texas”. San Antonio is the first of the four to open. The Fort Worth post went up on 2 November (UTC).
Against Waymo
Semafor reported on 8 November that Waymo operates commercially in 15 US cities, as we noted in Anti-Waymo Op-Eds Scored Up to 95% AI-Written, None Labelled. The two counts are not like for like: ours lists cities Tesla’s account names for service, while Semafor’s refers to commercial operation, and the service areas and vehicles differ.
The fight over where robotaxis may operate is in the anti-Waymo op-eds piece. What is new here is a second Texas city named within a week and the first opening from Tesla’s October “coming soon” list.
The Structural Read
As we read the account’s posts, Tesla named two Texas cities for service within a week: Fort Worth in a 2 November post and San Antonio in a 9 November post.
As we read the 21 October list, San Antonio is the only one of the four coming-soon cities that is in Texas; Las Vegas, Jacksonville and Phoenix are the other three, and the account has not given dates for them in the posts we read.
As we read the posts, the city count and the service model are separate questions: Tesla described Austin-metro service as unsupervised in June, and its San Antonio posts do not say which arrangement applies there.

Three Implications
FOR RIDERS IN SAN ANTONIOTesla’s account says service is available from 5 a.m. on 9 November inside a launch geofence covering central San Antonio; fares and hours were not stated in the posts we read.
FOR THE COMING-SOON LIST Las Vegas, Jacksonville and Phoenix remain listed as coming soon in the account’s 21 October post, with no dates given there.
FOR THE WAYMO COMPARISON Semafor reported Waymo operates commercially in 15 US cities; our nine-city count of Tesla’s posts uses a different definition and is not like for like.
The framework argues: “In any product cycle, there are two curves to follow. The first is what your underlying technology can do. The second is what your users can actually do with it.”
As we read it, a city count tracks the second curve: where riders can actually hail a Robotaxi, which is a separate question from what the driving software can do. The framework predates this launch and does not discuss Tesla or any company named here.
What Is Not Established
Tesla’s posts give no fares, fleet size, hours or safety-monitor arrangement for San Antonio, and we did not find a Tesla press release. The city count is ours, built from the @robotaxi account’s posts; it does not include cities the account has not named, and it does not measure service-area size or ride volume.
This Week In The AI Supercycle
The Great Convergence of Capital, Power, and Geopolitics
This week’s issue: for two years the AI build-out was priced as a supply story, and last week as a credit story. This week it was priced as a permission story, and the answer arrived as a cost, not a ban.
Tesla’s @robotaxi account says the service is available in San Antonio from 5 a.m. on Monday, 9 November. By our count of its posts, that makes nine named cities and five in Texas, and San Antonio is the first of the four cities listed as coming soon on 21 October to open.
A note on sourcing. The launch is taken from posts by Tesla’s official @robotaxi account on X, read through the X API on 9 November 2026. The city count is our tally of that account’s posts; the 19-day span is our arithmetic. We did not contact Tesla.
