Tesla opens Cybercab rides in Austin with a 45-car fleet

Autonomy, trade policy, and a détente in Washington all moved on the same day. Here's what landed. Tesla said Thursday it is offering Cybercab rides in "limited areas of Austin, Texas" — the first time the two-seater with no steering wheel and no pedals has carried the public. State records show Tesla had 420 autonomous vehicles registered in Texas as of Wednesday evening, 45 of them Cybercabs, against Waymo's 988 in the state. The launch has been oddly muted: as of Thursday evening Tesla had p

Crusoe raises $3 billion at a $30 billion valuation

The AI buildout's capital markets didn't slow down after hours on Thursday: an AI data center operator quietly tripled its valuation, a smart ring maker filed to go public with real profits, and an autonomous trucking company took a third swing at a listing. Crusoe has closed a funding round of more than $3 billion at a post-money valuation of roughly $30 billion. Atreides Management and Valor Equity Partners co-led the round, with Mubadala Capital — the alternative asset manager owned by Abu D

Adobe hands the CEO job to its agentic software chief

Two big ownership stories landed after the OpenAI noise died down: Adobe finally named the person who has to defend it against AI-native rivals, and Oura put real numbers behind the smart-ring boom it helped start. Adobe will hand the chief executive role to Anil Chakravarthy on December 1, ending Shantanu Narayen's run of more than 18 years at the top. Narayen stays on as executive chair, and the board framed the pick as continuity with a twist: Chakravarthy joined Adobe in January 2020 to run

Jane Street commits $13 billion to Crusoe for GPUs

The trading firm's second enormous compute deal in a month, plus a forecasting model that beats everything and can't be used commercially. Jane Street signed a five-year cloud contract with Crusoe worth about $13 billion, its second huge GPU commitment in weeks. Bloomberg reported the deal, which gives the trading firm clusters of GPUs and supporting infrastructure for AI training and inference through Crusoe's cloud platform, and Reuters confirmed the report. Crusoe is the highest-profile clou

Nvidia signs the Hugging Face deal at $12.9 billion

The rumors are over. Nvidia confirmed Thursday that it has a definitive agreement to acquire Hugging Face, the closest thing the open-model world has to a town square — and on the same day, a UAE research institute shipped what it calls the largest fully open model fleet in history, with training data attached. Nvidia has agreed to acquire Hugging Face for $12,930,300,000, ending a week of speculation and putting the chipmaker in ownership of the platform where most of the world's open models l

Microsoft named a segment "Agents and Infra." Read the fine print

Microsoft did two things on Wednesday that look like bookkeeping and are not. It told investors what Azure earns — $29.42 billion in the June quarter, a figure it had refused to publish for a decade — and it collapsed three reporting segments into two, one of which it named "Agents and Infra." Then it quietly took away the segment-level cost and margin detail it had been publishing all along. You now know the top line. You know less than you did about what it costs to produce it. What actuall

Wonderful raises $550 million at a $5B valuation for the enterprise AI OS

Two enterprise stories worth your attention this hour: an Amsterdam startup just closed one of the largest AI funding rounds of the year by selling companies a shared operating layer for agents, and Saudi Arabia's Humain is putting together a $2.5 billion fund to finance a quarter-gigawatt of domestic data center capacity. Wonderful closed a $550 million Series C at a $5 billion valuation, led by Insight Partners with Salesforce participating. The Amsterdam company — founded just 20 months ago

Fluidstack triples to an $18B valuation in six weeks on Jane Street's bet

Two AI stories worth a second look today — a neocloud jumps 2.4× in valuation between rounds, and Moonshot quietly files for Hong Kong. Neocloud Fluidstack closed a $1.5 billion round led by Jane Street at an $18 billion-plus valuation, according to people familiar with the matter — barely six weeks after announcing a $750 million round at $7.5 billion in July. The pace is the story: Fluidstack is a UK-built, GPU-heavy hyperscaler that rents compute to AI labs, and the speed of the markup sugge

The Take — Uber's war on robotaxis is a toll booth, not a conscience

The Take — Uber's war on robotaxis is a toll booth, not a conscience

Uber is not trying to stop robotaxis. It is trying to make sure that when they arrive, they arrive on Uber's platform and pay Uber a cut. Every piece of the company's new labor politics — the union alliances, the workforce-transition language, the 85 percent rule its lobbyists are pushing in New Jersey — is aimed at that outcome, not at slowing the technology down. I think the distinction matters more than it sounds, because it changes who we should root for. If this were a company making commo

Microsoft finally puts a number on Azure: $29.4 billion a quarter

Two numbers landed this morning that say more about where AI money is actually moving than any benchmark table: Microsoft broke out what Azure earns, and Alibaba's Tmall started selling model tokens next to the phone credit. Microsoft disclosed quarterly Azure revenue for the first time ever on Wednesday — $29.4 billion in the June quarter, $101.9 billion for the fiscal year ended June 30. The figure came in a presentation that also collapses Microsoft's three reporting segments into two: "Agen

Cognition's valuation nearly doubles to $47B in a new $1B round

The agent economy repriced itself again overnight. Cognition, the studio behind the Devin coding agent, is raising around $1 billion at a valuation near $47 billion — nearly double the $26 billion it commanded just four months ago, per Bloomberg. Cognition is raising roughly $1 billion at a valuation near $47 billion, nearly double its May mark, as demand from investors ran to almost $10 billion. Almost exactly a year after the company raised at $4 billion and months after it closed a billion-d

AfterQuery hits $3.2B — Y Combinator's fastest unicorn ever

Two signals tonight about where the money and the machinery are going: a 20-month-old training-data startup is now worth $3.2 billion, and CrowdStrike has decided that the place to stop a rogue AI agent is the laptop it runs on. AfterQuery, an AI training-data startup founded in January 2025, is reportedly valued at $3.2 billion — the fastest company in Y Combinator's history to reach unicorn status. Forbes first reported the round; TechCrunch said the company could not be immediately reached f
