X is dominated by the memory supercycle, optical supply deficits, and AI credit structures, with a live disagreement on whether AI capex is earnings-driven or a financing bubble.
Themes on this desk
Memory supercycle
Goldman sees DRAM/NAND deficits worsening into 2029-2030, Bernstein models $1.3T of memory operating profit by CY28, and Morgan Stanley says Nvidia can absorb a 91.7% HBM cost increase at a 72% margin floor.
AI credit and off-balance-sheet
Hyperscaler off-balance-sheet commitments hit $3.6T, up $500B in a month, Broadcom's AI XPV platform is raising up to $60B for Anthropic chips, and Oracle's 2035 IG bond trades near 95.
Optical supply deficit
Lumentum's CEO said the company will undership demand by 70%, Coherent's InP expansion is sold out, and Barclays raised optical port estimates to 100M in CY26 and 200M in CY27.

Market Radar →Goldman sees NAND/DRAM shortage worsening through 2027 and undersupplied into 2029-2030
pequityresearch relays a Goldman Sachs report projecting DRAM and NAND supply deficits of 5.9% and 4.6% in 2027, unusually tight manufacturing capacity and surging enterprise model usage prolonging severe tightness through 2028, structural pricing power for memory producers like Kioxia, and global token consumption expanding 24-fold to 120 quadrillion tokens monthly by 2030; Kioxia is already negotiating long-term agreements to lock in 50% of 2028 output, with slower consumer AI adoption the key downside risk. Tickers tagged: MU, DISK, DRAM, EWY.
Goldman Sachs: NAND and DRAM shortage to become worse in 2027 and likely to remain undersupplied in 2029-2030.
A multi-year memory supply deficit implies sustained pricing power and margin expansion for memory producers, a structural bull case for MU and Korean memory exposure (EWY) that extends well beyond the current cycle.
Watch DRAM/NAND contract pricing trends and whether Kioxia's 2028 supply lock-ins are confirmed; a demand air-pocket in consumer AI workflows would invalidate the deficit thesis.
Source →Lumentum CEO says optical supply will undershoot demand by 70%
Lumentum CEO Michael Hurlston said that next year, with the advent of CPO and NPO in 2027, the company estimates it will be undershipping demand by 70%, supplying only 30% of what it is being asked to supply, and that balance is a long way off, perhaps 2029/2030.
undershipping demand by 70%. We can only supply 30% of what we are being asked to supply."
A supplier-guided 70% shortfall implies optical component pricing power and revenue upside well beyond current demand expectations, and constrains how fast AI datacenter interconnect capacity can scale.
Watch Whether Lumentum's reported shipments and guidance track the 30%-of-demand figure, and whether CPO/NPO adoption timelines slip or accelerate.
Source →Burggraben: Oracle's $300bn Stargate bet risks a Lehman moment as its 2035 bond trades at 95
Alexander Stahel (BurggrabenH) argues Oracle has 'bet the farm' on AI data centers: roughly $300bn in commitments supported by a legacy business earning about $20bn, with the gap debt-financed, and Oracle's $18bn 2035 investment-grade bond issued in September now trading around 95 — well below par and outside where IG should trade. He notes the Stargate deal lets OpenAI recommit or walk away after roughly five years, about a decade before many Oracle leases expire, so if OpenAI's revenue growth merely slows it may neither need the compute nor be able to pay for it, leaving Oracle with extraordinarily expensive, illiquid assets. He calls it a textbook 2000 setup and says Larry 'applied for his own little Lehman moment.'
Meanwhile, Oracle’s $18bn 2035 investment grade bond, issued in September, now trades around 95.
A specific, falsifiable credit-market signal (an IG bond trading at 95) attached to the largest AI data-center commitment is a concrete early-warning indicator for the entire AI-infrastructure financing complex, not just Oracle.
Watch Whether Oracle's 2035 bond recovers toward par or deteriorates further, and whether OpenAI's revenue growth rate decelerates before the ~5-year recommit window.
Source →Broadcom platform raising up to $60B to fund Anthropic chip purchases
Beth Kindig reports that Broadcom's $AVGO AI XPV platform is said to be raising up to $60 billion in financing to help fund chip purchases for Anthropic, split into a $42 billion Class A senior-secured tranche and an $18 billion Class-B junior tranche.
Broadcom’s $AVGO AI XPV platform is said to be raising up to $60 billion in financing to help fund chip
A $60B structured financing tied to a single AI customer is a large-scale read on how Broadcom is monetizing custom AI silicon and on the credit appetite for AI infrastructure buildout; tranche structure signals where risk is being placed.
Watch Confirm the raise size and tranche structure via Broadcom, Anthropic or deal documents; failure to close or a materially smaller raise would invalidate the read.
Source →Hyperscaler off-balance-sheet commitments hit $3.6T, up $500B in one month
Zero Hedge reports hyperscaler off-balance-sheet commitments reached $3.6 trillion as of Sept 30, an increase of $500 billion in a single month, mostly tied to Nvidia, and expects the figure to triple after 10-Qs are filed.
That's an increase of $500 billion in ONE MONTH (mostly NVDA) Expect this to 3x after 10Qs hit.
Rapidly growing off-balance-sheet AI commitments concentrate counterparty and financing risk in the AI supply chain, with NVDA-linked obligations the largest driver; disclosure in upcoming 10-Qs could reprice AI infrastructure credit and equity risk.
Watch 10-Q filings confirming the $3.6T figure and whether the expected 3x increase materializes; any hyperscaler disclosure of lease/commitment terms tied to NVDA purchases.
