@OpenAI is private. Its revenue correction still shook public markets. On Thursday the @FT reported that OpenAI’s annualised revenue run rate was close to $50 billion, against the $70 billion previously reported. @Oracle’s shares fell 5.5% that day. OpenAI says its business was still growing rapidly. The correction exposed how much confidence rested on a number that could not be reconciled in public. The financial connections run through contracts. @Nvidia guarantees parts of OpenAI’s infrastructure commitments. Oracle has signed long leases to supply computing. @Broadcom backs financing for chips leased to @AnthropicAI. A laboratory’s spending, a cloud’s backlog and a chipmaker’s orders can all depend on the same final customer demand. This week’s Sunday Signal follows those contracts and the borrowing behind them to explain who carries the risk if the expansion disappoints. For Britain, there is an opportunity here. AI can keep delivering useful work while investors lose money. Cheaper models could make it more economical to use the knowledge inside an engineering firm’s drawings, maintenance records and repair histories. The commercial value comes from turning that knowledge into better decisions and work customers will pay for. That is the purpose of the Stocksbridge proposal. Start with a paid pilot. Prove the available power, the customers and the full cost of doing their work. Expand when the evidence supports it. If existing capacity offers better value, use it. Plus the weekly Tech & AI Layoff Tracker, including what employers actually say about AI’s role. Build small, build under British control, and build for the bust. thesundaysignal.ai/publish/p…

The Sunday Signal podcast is live: When Cheap Labour Is No Longer Cheap Enough. Recorded off the back of a week in India with the Great North trade mission. Cheap labour can delay automation inside India; it cannot stop overseas customers automating the work they once sent there. What that means for a grocery rider in Varanasi, a graduate in Bengaluru, and an ageing Britain that needs machines to do more of the work and a share of what they earn. Then @AnthropicAI's investors discussing $1.5 trillion rather than $2 trillion, and the @Accenture memo that puts Claude usage beyond $29 a month on a project code: when a task gets cheaper, who keeps the saving? Plus the Tech & AI Layoff Tracker. thesundaysignal.ai/p/when-ch…

Fair play to @British_Airways @Starlink got to watch #swfc win 5-0 today on the Mumbai to LHR flight. @EastMidRailway take note I can stream 30,000 ft over SE Asia but not in Sheffield…

They say never meet your heroes. I disagree. Flying from Hyderabad to Mumbai with the Great North trade mission, I found myself sitting next to cricket legend Sunil Gavaskar. An absolute gentleman who spoke warmly of his great friend and fellow Yorkshireman @GeoffreyBoycott. He even recorded a special welcome message for our Northern mayors. Sometimes your heroes exceed expectations. What a privilege! @olivercoppard @DSkaith @TracyBrabin @KiMcGuinness @bevcraig @luke11campbell @SouthYorksMayor @MetroMayorSteve @YorkshireCCC @BCCI @ICC #SunilGavaskar

Exactly 8 years ago today, I was in India receiving this wonderful welcome. Today, I’m heading back. This time, it’s something rather special. I’m joining The Great North India Mission, bringing together nearly 200 business leaders, universities and civic representatives from across the North of England, alongside our Northern mayors. It’s the first time our Northern mayors have come together on a trade mission of this scale, and the first major regional response to the UK-India Free Trade Agreement. The North has a £340 billion economy, world-class manufacturing, outstanding universities and some of Britain’s most exciting technology businesses. India has extraordinary ambition, talent and investment capital. The opportunity is enormous. For me, representing Yorkshire AI Labs, the priority is attracting Indian investment into Northern businesses, particularly in AI, advanced technology and innovation. We need to turn introductions into investment, partnerships into businesses and opportunities into jobs. It’s good to see Minister @jreynoldsMP, our High Commissioner Lindy Cameron, and Northern leaders @SouthYorksMayor @olivercoppard, @WestYorkshireCA Tracy Brabin, @KiMcGuinness, @MetroMayorSteve, David Skaith, Luke Campbell and @bevcraig working alongside businesses to strengthen the relationship between India and the North. Eight years ago, I came away impressed by India’s ambition. This time, I want to come back with investment. #GNIndia26 #TheGreatNorth #India #YorkshireAILabs

Yesterday I mainly wore a top hat and morning dress around Sheffield, to puzzled onlookers. In my defence, I was in good company. On the first Tuesday of every October, the Company of Cutlers in Hallamshire install a new Master Cutler at Cutlers' Hall, then walk in procession, top hats and all, to Sheffield Cathedral for a service and back again for lunch. Parliament incorporated the Company in 1624 to train apprentices, register makers' marks and keep Sheffield blades honest. Their searchers once had the right to enter workshops and hunt out shoddy goods. Those raids have stopped. The top hats have not. Congratulations to Ian Nicholls, now the 387th Master Cutler and, for the year ahead, the voice of South Yorkshire manufacturing in London and beyond. Thanks too to Professor Keith Jackson, who completes his year in office and becomes Immediate Past Master. Four centuries on, Sheffield still dresses up for the people who make things. Quite right too. #sheffield #manufacturing #companyOfCutlers

8 firms want £20bn of sovereign compute. Britain already owns the grid nodes, the photonic chips are made in Oxford, and the state is moving to buy a steelworks on a 400 kV grid node. The plan nobody has written, free this Sunday. open.substack.com/pub/davidj…

Is AI going to take over? Turn off the servers. This week's Sunday Signal audits the extinction panic: the 10% that was one man's guess, the "rogue agents" that were one model with the door left open, and the $2 trillion listing behind the slowdown. Free every Sunday. thesundaysignal.ai/p/turn-of…

People who have nothing to do with technology have started asking me the same question: is AI going to take over? Tomorrow's Sunday Signal answers it, then audits the month that made them ask. The 10% extinction figure that turned out to be one man's personal guess. The "rogue AI" that hacked Hugging Face, reconstructed from OpenAI's own report: one model, 1,200 copies, and a door the engineers had known about since May. The slowdown essay, read for what it actually asks for, weeks before a reported $2 trillion listing. And the layoff tracker, where the only off switch anyone flipped this week was at Oracle, at six in the morning. Issue #72: Turn Off the Servers. Tomorrow, free, every source linked. thesundaysignal.ai

Now I'm not the biggest fan of Shakespearean tragedies, but... Sheffield Theatre's production of King Lear is brilliant. Bravo @cruciblesheff @tomwbird for a quite brilliant production. Ian McDiarmid's performance is a must-see, and he's 82!!

I’ve given @EastMidRailway plenty of stick. Credit where it’s due: these new trains are good. I’m heading from St Pancras to Sheffield, with a working internet connection all the way from London. By Leicester, I’d finished and published this week’s Sunday Signal and the podcast. That makes a real difference. Time I’d normally spend fighting for a connection has become time I can actually use. Reliable internet on a train isn’t a luxury. It’s productive working time. More of this, please, EMR.
