Van Aert won stage 15 out of a five-man move. The green jersey has stopped being a sprinter’s prize.

Wout van Aert took Córdoba from a selection rather than a bunch kick — his second stage win of this Vuelta — and now leads the points classification by 108. Two of the top three in green ride for the same team. Enric Mas carries a 2:06 lead into the final week.

China’s third-most-valuable AI lab is the first one going public.

Moonshot AI has filed confidentially in Hong Kong for a listing that would raise about $3 billion at a $50 billion valuation. DeepSeek is marked at roughly $74 billion. Z.AI at about $66 billion. Neither has filed. The lab with the least private capital is the one reaching for the public market first.

The SEC reopened a rulebook it hasn’t touched in 40 years. The question inside it: is a wallet an address?

On 1 September the Commission proposed the first substantive rewrite of its transfer-agent rules in about four decades. It legalises nothing. It asks, on the record, how the official register of who owns what is supposed to coexist with a distributed ledger — and gives the industry 60 days to answer.

Tesla certified the Cybercab itself. NHTSA opened a probe within hours.

The two-seaters have no steering wheel, no pedals and no fitted mirrors. Tesla told regulators they comply with every applicable federal safety standard. The investigation covers roughly 1,000 vehicles and turns entirely on the word “applicable.”

The 10-year hit 4.82%. The tell is what traders are paying to hedge the next leg.

Investors have spent millions in premium on Treasury options that only pay off if yields climb further — one position targets the 30-year at 5.7% by end-November. Spot is at its highest since November 2023. The conviction is showing up in the options market, not the cash market.

An AI wrote 13 million lines of maths in eleven days. A compiler checked every one of them.

Anthropic says Claude produced the first end-to-end machine-checked proof of Fermat’s Last Theorem in Lean 4 — roughly 30,300 theorems, about six billion output tokens, largely unsupervised. Mathematicians had budgeted years. The speed is not the point.

Google’s new weather model forecasts wind at 100 metres. That number tells you who the customer is.

WeatherNext 3 initialises every hour on a 5km grid instead of every six hours on a 25km one, and reads satellite data directly rather than waiting for a cleaned analysis. The consumer wrapper is Search and Maps. The product is a grid-balancing input.

Credit spreads look calm. About $1 trillion of bonds disagree with their own ratings.

The amount of debt trading at spreads unusually wide for its rating has more than doubled this year — roughly $580bn in the US and close to $400bn in Europe. Meanwhile the Boston Fed finds PIK loans have gone from about 6% of BDC books to roughly 10%. Index-level calm is doing a lot of hiding.

Google started retiring Assistant yesterday. The detail that matters is that you can’t switch back.

The phase-out began 4 September and rolls across Android phones, tablets, Wear OS, headphones and phone-projected Android Auto over several weeks. Until your device flips you can toggle between Assistant and Gemini. Once it flips, the toggle is gone.

ChatGPT ads went self-serve in 52 countries. That is the part that matters.

A $1 billion annualised run rate in under 200 days is the headline. Opening Ads Manager to anyone with a card is the decision — managed sales is a pilot, self-serve is a business.

Nvidia is putting $2 billion into a company whose job is buying Nvidia chips.

Nscale is raising about $3.5 billion before a New York listing — $2bn strategic, $1.5bn of convertibles led by Third Point. The convertible cap, not the headline, tells you where this prices.

Ripple just made tokenisation a one-vendor decision. That is the whole story.

Ripple Custody is now embedded inside SettleMint’s lifecycle platform — custody, issuance, compliance, settlement and servicing in a single procurement. Asia Pacific first. The bottleneck was never the technology.

SoundHound paid $43 million for LivePerson. The deal was actually $250 million.

The equity cheque was smaller than most seed rounds. Retiring the debt took 36.9 million shares — and that, not the purchase price, is the transaction.

Hyperscalers have sold $219bn of bonds this year. Buyers used to line up five deep. Now it’s two.

AMD built a deskside box that runs trillion-parameter models with the network cable unplugged.

The Threadripper Halo Station pairs 96 Zen 5 cores with liquid-cooled Instinct accelerators and up to 576GB of HBM3E. The target isn’t Nvidia’s chips — it’s Nvidia’s DGX Station.

Diesel just set an all-time high. The shortage is refineries, not barrels.

$5.85 a gallon nationally, past the June 2022 record of $5.81 and up nearly 60% year on year. Crude retreated this week. Those two facts belong in the same sentence, and that is the whole story.

An earnings beat built on tariff refunds, and a 9% comp decline underneath it.

Lululemon posted $2.92 adjusted EPS against a $1.82 consensus — with 86 cents of it from tariff refunds and interest. Revenue fell 4%, comps fell 9%, and full-year EPS guidance came down by roughly $1.45. The stock did the honest thing.

A trading firm bought $13 billion of compute. The landlord's valuation tripled.

Crusoe closed a $3 billion Series F at roughly $30 billion post-money, ten months after a $10 billion mark. The re-rate followed a five-year, ~$13 billion cloud contract with Jane Street. Who signed it matters more than how big it is.

Thirty minutes on a bike at night erased the memory cost of a four-hour night.

88 adults, 4.5 hours in bed, 80 face-name pairs to remember. The group that cycled easy before sleep recalled them like people who slept 8.5. The caveats matter as much as the result.

Microsoft just priced transcription at ten cents an hour. That is the new floor.

The crypto industry’s year comes down to seven Democratic votes on 15 September.

Vale spent three years building an IPO. A political objection ended it without a vote.

Vale Base Metals — copper, nickel and cobalt across five countries — was carved out in 2023 to be listed. The listing is now shelved indefinitely, and the reason is not the market.

Payrolls came in three times hotter than forecast. The two-year noticed first.

162,000 jobs in August against a 53,000 consensus, unemployment steady at 4.1%, and June and July revised up a combined 55,000. September hike odds went from a coin flip to roughly 60%.

OpenAI declared the “AGI era.” The same model scores 62.7% on a neutral harness.

GPT-6 Astra posted 99.9% on ARC-AGI-3 using OpenAI’s own test rig. Run it through the provider-neutral one and it drops 37 points. Both numbers are real. Only one of them is yours.

Broadcom’s AI revenue grew 221%. The number that moved the stock was 73%.

Record quarter, ninth straight beat, AI semiconductor revenue of $16.7bn and a guide to $21.7bn next quarter. Shares fell anyway, because consolidated gross margin is guided to 73% against 78% a year ago — and Broadcom told everyone exactly why.

The federal government just told a judge that training AI on copyrighted text is fair use

The Justice Department filed a statement of interest in the consolidated OpenAI copyright litigation, urging Judge Sidney Stein to find for fair use and warning that a contrary ruling would weaken US competitiveness and national security. It is the first time Washington has taken a formal side in any of these cases.

Uber cut 3,300 jobs. The number that actually matters is seven.

The headline is a 10% reduction, Uber’s largest since the pandemic. The structural number is buried underneath it: a 20% cut to the population sitting seven or more layers below the CEO, and a near-halving of teams with one or two direct reports.

The GLP-1 muscle-loss panic keeps failing to replicate. The trials find 80–85% of the loss is fat.

A 36-study analysis in the International Journal of Obesity, a Cell Reports Medicine paper spanning mice and humans, and a debate at the ADA’s 2026 Scientific Sessions all land in the same place: no disproportionate loss of muscle. What that does not mean is that you can skip the lifting.
