    Ep. 032 - 300 Datacenter Bans, 3 Projects Delayed: Moratoriums Explained (Datacenter, Energy) | Maya Barkin, Reyk Knühtsen, Jordan Nanos

    More than 300 towns, cities, and counties have voted to pause data centers in the past 18 months. Maya Barkin (@mayabarkin) and Reyk Knühtsen (@robotknower) from the SemiAnalysis Data Center, Energy, and Industrials team join Jordan Nanos (@jordannanos) to explain what a moratorium actually is, how they mapped every one of them against the US project pipeline, and why only three projects are being delayed. Plus: the SpaceX de-annexation in Brownsville, New York vs Texas, why politicians love a moratorium, and the surprising amount of alpha in anti-data center Facebook groups. Jeremie Eliahou Ontiveros (@JeremieEO) drops in from Bangkok.

    Ep. 031 - EMERGENCY EPISODE: Are We Doomed? | Jordan Nanos, Doug O'Laughlin, Max Kan, Joey Brookhart

    Emergency episode. Doug O'Laughlin (@Fabknowledge) , Joey Brookhart (@SaasquatchC), and Max Kan (@maxkan) join Jordan (@JordanNanos) to talk through Dario's "We Must Pace the Frontier" blog and the responses from Sam Altman and David Sacks. Does pacing actually mean less compute, or a lot more? Plus the Hugging Face incident, Moonshot serving Claude, and the security behaviour that keeps them up at night. 0:00 Cold Open 2:50 Glorified Neoclouds 8:21 Pacing the Frontier 12:53 Safety Eats Compute 20:38 Hugging Face Lessons 30:52 Moonshot Serving Claude 36:37 The Coxson Resignation 38:27 Two-Year Predictions 49:19 Regulation Under Trump 57:21 Hotter or Cooler

    Ep. 030 - Long Live the Short King: Why 4-HI HBM Wins (Memory) | Myron Xie, Jordan Nanos

    NVIDIA previewed Rubin Ultra at 1TB of HBM per package. The part that ships will carry 192GB. Myron Xie and Jordan Nanos get into how the design fell that far, why the reason is supply and not performance, and why shipping less memory per chip might be the right call anyway. For the first time in recent memory, NVIDIA's next flagship will have less capacity than the one it replaces. Read More: https://newsletter.semianalysis.com/p/long-live-the-short-king-why-4-hi

    Ep. 029 - Modular Data Centers Cut Build Time to 12 Months (Datacenter, Energy) | Nico Bontigui, Jordan Nanos, Nigel Chiang, Eric Wen

    Traditional data center builds ran 18 to 24 months, sometimes past three years. Modular construction cuts that to 12. Jordan Nanos (@JordanNanos) sits down with Eric Wen, Nigel Chiang, and Nico Bontigui to map what modular actually means, from MEP heavy skids to full containerized builds. They break down why the bottleneck moved from construction time to labor, why welders and electricians are the real constraint in Abilene, and how time to power translates directly into tokens at 40 to 100 million dollars per megawatt.

    Ep. 026 - PJM's $12B Modeling Mistake Is Hitting Ratepayers Again (Datacenter, Energy) | Robert Boswall, Jordan Nanos

    PJM overpaid $12 billion across two capacity auctions, and the same modeling error is set to repeat in an upcoming emergency auction. Robert Boswall (@RobertBoswall) and Jordan Nanos (@JordanNanos) break down how the largest grid in America, 13 states and 66 million people, inflates demand while constraining supply. The result is scarcity pricing that ratepayers absorb, not the data centers driving the narrative. Of the $63 billion spent across four auctions, Boswell estimates $12 billion was avoidable, split $7 billion and $5 billion across the 2025-26 and 2026-27 auctions. This is the mechanics behind every headline blaming AI for rising power bills.
