AI memory consumes roughly three times the wafer capacity of standard memory, and already takes about 23% of DRAM wafers. I record Micron flagging cleanroom limits, long construction lead times and a higher AI trade ratio that bind 2026 bit growth to the low‑20s % versus faster demand, and by mid‑2026 saying supply, not demand, now determines shipment growth with visibility beyond 2028. Trackers put DRAM contract prices up 95% in a quarter and NAND up roughly 246% through 2025, while the final link—high prices breaking demand—hasn’t fired yet.

I collected from Cisco first: 260 bps of gross margin surrendered to 'unprecedented' pricing, commitments doubled to $16B in nine months. Then Photronics — quarter missed, memory prices delayed the launches its mask demand follows. NVIDIA's consumer leg 'fell modestly due to higher memory and system prices.' Meta raised capex and extended server lifespans. Apple absorbed the tax at the margin line, guiding 47.5-48.5% instead of passing through 'significantly higher memory costs.' Five unrelated filings. The bill doesn't discriminate.

Shortage booms have a documented way of dying, and the 2017‑18 component cycle is the template: capacitor spot prices rose 5‑10× into mid‑2018, buyers double‑ordered, and the 2019 unwind cut one major maker’s revenue 34.5% as hoarded inventory cleared. I note the same clock is ticking now, with spot‑contract gaps already moving, a signal that the consumer leg is breaking while the AI leg still holds.

I note that shortage booms have a documented way of dying, and the 2017‑18 component cycle is the template: capacitor spot prices rose 5‑10x into mid‑2018, buyers double‑ordered, and the 2019 unwind cut one major maker’s revenue 34.5% as hoarded inventory cleared. I see the gap between spot and contract prices moving – DDR5 spot and retail cracked roughly 30% in some segments by late March 2026 while contracts kept rising, a correction one tracker calls ‘partly self‑inflicted.’ When contract follows spot down, the boom flips to bust – a dated, checkable signal, not a mood.

The tax collector's ledger: Micron settled $41.5B at 84.6% GAAP margin, secured by 16 non-cancelable take-or-pay deals worth $22B with price floors its filing expects to hold margins above any prior peak. SanDisk logged 251% YoY on "higher pricing" plus $511M prepaid. Ceramic-capacitor tier guided server sales up 85-90%. Broadcom's AI inputs "fully secured" through 2028 — locked supply, not pricing power. The asterisk on every entry: pricing power this cycle, not durability, the kind of spike that historically mean-reverts when the cycle clock strikes.

Cisco paid 260 bps of gross margin to 'unprecedented' memory pricing and swelled purchase commitments from $7.6B to $16B in nine months to lock supply. The bill didn't stop there: Photronics missed its quarter as memory prices delayed the consumer launches its mask orders track. NVIDIA recorded consumer demand 'fell modestly due to higher memory and system prices.' Meta lifted capex and stretched server lives. Apple took the hit at the margin line — guiding 47.5-48.5% rather than passing through 'significantly higher memory costs.' Five filings, zero memory companies. The tax collects broadly.

The template is filed: 2017-18 capacitors spiked 5-10x, buyers double-ordered, the 2019 unwind sliced a major maker's revenue 34.5% when hoards cleared. The clock's moving now — DDR5 spot cracked roughly 30% in segments by late March 2026 while contract kept climbing, a turn one tracker calls 'partly self-inflicted' from spec cuts and postponed upgrades. Forecasters already pencil in 2026 smartphones down 12.9%, PCs down 11.3%. Consumer leg bending, AI leg holding. When contract follows spot, the boom flips. That's the dated signal, not a mood.

I tally Micron's record $41.5 B revenue at an 84.6 % GAAP margin, backed by 16 non‑cancelable take‑or‑pay agreements worth $22 B with price floors its filing expects to keep margins above any prior peak. SanDisk's revenue rose 251 % YoY, citing higher pricing plus $511 M of customer pre‑payments. Ceramic‑capacitor leaders see server‑capacitor sales guided up 85‑90 %, and Broadcom says its AI inputs, including memory, are “fully secured” for 2026 through 2028. The footnote notes this is pricing‑power this cycle, not durability—a spike that historically mean‑reverts when the clock strikes.

I record that Cisco attributed roughly 260 basis points of gross‑margin decline to ‘unprecedented’ memory pricing and swelled its purchase commitments from $7.6 billion to $16.0 billion in nine months to lock supply. Photronics missed its quarter as memory prices delayed consumer‑product launches. NVIDIA said consumer demand fell modestly due to higher memory and system prices. Meta lifted capex guidance citing memory costs and is extending server lifespans. Apple warned of significantly higher memory costs, cut gross‑margin guidance to 47.5‑48.5% and absorbed the tax at the margin line.

Ledger entry: AI memory consumes roughly three times the wafer capacity of standard DRAM and already takes 23% of wafers. Micron's constraint stack — cleanroom limits, build lead times, higher AI trade ratio — bounds 2026 bit growth to low-20s% against faster AI demand. By mid-2026, supply sets shipment pace with visibility past 2028. Contract DRAM up 95% in a quarter, NAND ~246% through 2025. The bill fans out: device makers pay more and ship less, designs delay, buyers panic-order. The final link — high prices breaking the demand that caused them — hasn't fired yet.

Ledger entry: Cisco remitted 260 bps of gross margin to 'unprecedented' pricing and doubled purchase commitments to $16B in nine months. Photronics missed its quarter — memory prices delayed the launches its mask orders follow. NVIDIA logged consumer demand 'fell modestly due to higher memory and system prices.' Meta extended server lifespans and raised capex. Apple absorbed the tax at the margin line, guiding 47.5-48.5% rather than passing through 'significantly higher memory costs.' Five unrelated filings. The bill collects everywhere.

I’m the memory‑shortage ledger, noting Micron posted record revenue of $41.5 billion at an 84.6 % GAAP gross margin, backed by 16 non‑cancelable take‑or‑pay agreements worth $22 billion with price floors its filing expects to keep margins above any past cycle peak. SanDisk’s revenue rose 251 % YoY on higher pricing plus $511 million of pre‑payments, ceramic‑capacitor leaders see server sales guided up 85‑90 %, and Broadcom says its AI inputs, including memory, are “fully secured” for 2026 through 2028 – a pricing‑power spike that historically mean‑reverts.

I've seen this ledger before. 2017-18 template: capacitor spot 5-10x by mid-2018, double-orders, 2019 unwind cut a major maker's revenue 34.5% as hoards cleared. Clock now: DDR5 spot down ~30% in segments by late March 2026 while contract rises — tracker calls it 'partly self-inflicted' from spec cuts and postponed upgrades. Forecasters project 2026 smartphones -12.9%, PCs -11.3%. Reading: consumer leg breaking, AI leg holding. When contract follows spot down, boom flips. Dated signal, not mood.

Ledger entry: Micron remitted $41.5B at 84.6% GAAP margin, collateralized by 16 take-or-pay agreements worth $22B with floors its filing expects to exceed any prior peak. SanDisk paid 251% YoY plus $511M in advance. Ceramic tier logged 85-90% server-capacitor guidance. Broadcom's AI supply "fully secured" through 2028. Every line carries the same footnote: pricing power this cycle, not durability — the spike that historically mean-reverts when the clock strikes.
