Episodes

• Week 31: The Shortage Moved to a Material You Don't Buy: Week 31: the shortage stopped being about memory. Lumentum's CEO says indium phosphide is running more than 30% below customer need and will become more acute than the memory squeeze. Corning's Optical Communications grew 32% with its AI data-center line up 65%, GlobalFoundries signed a proposed $300M CHIPS silicon-photonics LOI, and UMC's Singapore photonics cleanroom ramps late 2027. Meanwhile the general-purpose base came back — and Renesas is retiring a 50-year-old 6-inch analog and discrete line without a date. The honest counter: a 94.1% revenue forecast against 7.4% more silicon area shipped.
• Week 30: You Can Lock a Year of Supply and Still Not Know the Price: Week 30: the buy side stopped waiting and started signing — and what it signed away was optionality, not price. TSMC is reportedly planning 2027 wafer increases up to 25%; Intel and AMD reportedly locked about a year of Chinese server CPU volume without fixing price; NVIDIA and SK Group put more than $500 billion behind AI factories and memory. The honest counter is IDC's PC and smartphone unit declines.
• Week 29: The Money Showed Up. The Permission Didn't.: Week 29: TSMC committed ~$100B more to Arizona 2nm fabs and advanced packaging, funding the packaging gap — but New York's first US statewide data-center moratorium moved the binding constraint from capacity to permission. The money is arriving at every upstream layer; each dollar still has to pass a permit, a power contract, or an end-use rule.
• Week 28: The Shortage Got a Deadline — It's Years Out: Week 28: SK Hynix's CEO called 2027 the worst year of the memory shortage and expects demand to outrun supply beyond 2030 — backed by a $26.5B IPO. The suppliers are financing a multi-year shortage, and the bottleneck is spreading past memory to packaging, racks, and power.
• Week 26: The Spike Became the Baseline — The Cost Reached the Whole Board: Week 26: TSMC is reported to be hiking every advanced node and DDR2 jumped 55-60%, so the memory spike stopped being a line item and reset the whole bill of materials. The majors are financing a higher cost base — SK Hynix's $29B raise, Micron agreements, onsemi-Synaptics.
• Week 25: Your NAND Quote Is Not the Only Problem — The Channel Started Moving: Week 25: Silicon Motion says the retail SSD market has almost disappeared as NAND routes to AI data centers and OEMs buy third-party drives. The shortage moved from price into the channel — and AI demand stays funded while system makers buy around the memory wall.
• Week 24: Buyers Stopped Waiting for Memory — They Started Locking It In: Week 24: Biwin fixes its NAND price for 24 months, Nvidia and SK hynix lock a multi-year memory pact, and Xbox says 2027 storage will cost five times more. The biggest and most exposed buyers have stopped waiting for memory to get cheaper and started paying to lock it in.
• Week 23: The Market Hit $1.5T and Your Memory Quote Got Worse: Week 23 explains why record semiconductor growth and worsening memory quotes are the same story: AI infrastructure is pulling DRAM, NAND, HBM, storage, substrates, and power ahead of traditional buyers.
• Week 22: The Bottleneck Moved Below the Die: Week 22 moves below the foundry quote into substrates, bonding, power delivery, packaging routes, and AI factory architecture as the next procurement bottlenecks.
• Week 21: The Capacity You Quoted Just Got Sold: Week 21 explains how TSMC appropriations, AMD’s Taiwan ecosystem buildout, Nvidia data center revenue, and ADI demand reserve foundry, packaging, memory, and power capacity ahead of ordinary buyers.
• Week 19: The Recovery Is a Number Now. Allocation Is Next.: Week 19 follows ESIA’s Q1 chip sales print, Microchip, Infineon, onsemi, storage long-term agreements, and the capital signals that turn recovery into allocation pressure.
• Week 18: Three Million Users and the Mac Mini Sold Out: Week 18 connects OpenClaw adoption, Apple Mac mini shortages, Big Four AI capex, and earnings prints to a broader memory and capacity squeeze for procurement teams.
• Welcome to Supply Signal Radar: An evergreen introduction to Supply Signal Radar: why Semibuffer exists, how Supply Signal reads the semiconductor cycle, and what procurement teams should expect from the weekly audio brief.
• Week 17: The Other Side of the Trade Speaks: Week 17 tracks Intel’s bin-floor signal, Texas Instruments’ inventory cushion, and Lam Research demand as earnings reveal how the structural semiconductor gap is showing up across suppliers.
