Software Outpaces Hardware: Compute Shortage Limits Progress
Not enough compute is the correct take IMO. Which has quite a lot more implications if you think about it and play that out to its logical conclusion. Software still burdened by hardware’s inability to keep up. Maybe software is 2-3 years ahead of hardware?
AI Will Force a Massive, Lengthy Rearchitecture of Everything
All infra, all software, all services, will have to be rearchitected for AI. This is a long cycle.

TSMC's Customer Base to Quadruple High‑Revenue Clients by 2027
Doing some customer modeling on TSMC and this stat stands out: In 2023, TSMC had one customer (Apple) above $10 billion in annual revenue. By 2027E, it is projected to have four, including Apple, all above $20 billion.
Semiconductor Market Poised to Reach $2 T by 2030
As insane as it sounds (and again driven by ASP) it may hit $2T by 2030.
Anthropic's AI Layer Poised for $26B Revenue
We articulated this abstraction layer Anthropic is going after and how this turns into $$ in our full report on Anthropic and their revenue potential. The financial model we built end of February had them at $26B in 26...
Transistor and Memory Costs Are Rising Astronomically
When I say the cost to make transistors ($ per billion) has gone up.. I mean its gone UP.... Memory is even more insane, cost per gb is 🤯
Anthropic Positions Claude as Universal Productivity OS
Anthropic is on a full-fledged pursuit of usurping the productivity value from all other applications/software and taking it for themselves in Claude as the productivity OS.

Whole video pod of @T_h_e_Circuit and the points I made earlier in the week on memory, we discuss in the chapter timelines you can skip to.
Apple Boosts TSMC SoIC Capacity for AI Servers
Morgan Stanly on Apple custom ASIC for cloud/hybrid compute (chip code-named Balta): "Apple is materially ramping SoIC capacity at TSMC, pointing to a major push in Apple silicon for AI servers. TSMC (covered by Charlie Chan) is expanding its SoIC (System...
Mythos May Not Be Exclusively Trainium
We suspected this, which was why I hadn't yet commented on the sentiment that Mythos is a blackwell trained model. May not be 100% trained exclusively on any GPU/XPU in actuality.
Liquid Cooling Unlocks AI-Scale Compute Capacity

Rising Memory Costs Threaten AI ROI and Market Confidence
While we talk about memory prices 📈, and while that is true (great for memory names), I am worried about what this does to capex costs and in return on AI $$. If the cost to serve AI goes...
AWS Poised for Its Most Consequential Growth Phase
Seems a good time to resurface this report on the back of the Amazon shareholder letter. The AWS Acceleration Thesis: Why Amazon's Cloud Business May Be Entering Its Most Consequential Growth Phase https://t.co/nNOw2zxMk9
Intel Missed Chance by Denying Gelsinger's Foundry Investment
Can you imagine if Intel's board let @PGelsinger invest in the foundry capacity he asked them for? I agree, it seemed crazy at the time, but hindsight is 20/20.
Points 5 and 6 Define Cycle Durability, Not
I liked the $AMZN shareholder letter. I take point 4 with a grain of salt (trn is largely AWS as a customer and Anthropic). Points 5 and 6 are most important for the "durability" of the cycle debate. https://t.co/X7zQDnJ6YM
TSMC and Top Memory Makers Set Prices, Customers Agree
TSMC, and the three memory names right now, are the primary beneficiaries of a name your price market dynamic. Meaning they can literally name their price and customers will pay it.

2026 Market Forecast Jumps $200B, Extending ROIC Horizons
It is wild that about two months ago, consensus memory in dollars for 2026 was ~$600B and now people are saying north of $800B... Very challenging to square this with ROIC timelines now, as they will have to lengthen, and...
From $1T in 70 Years to $2T in Five
What no one saw coming about this, since most $$ estimates were on volume not ASP, is just that - this is simply costs going up. It took >70 years to hit $1T and it will go from...
TSMC Poised to Dominate Silicon Photonics Like AI Packaging
I'm glad TSMC COUPE is getting more attention of those in the weeds in optics. Our view: "TSMC is increasingly positioned to occupy the same role in silicon photonics that it came to occupy in advanced AI packaging." https://t.co/WMdxP2tF3R
Transformers: Powertrain Driving Grid Upgrade Surge
Why we who track the AI buildout should care about transformers. They are the “powertrain” of the grid upgrade cycle, with demand being driven by three forces at once: aging grid infrastructure, the shift toward renewables, and a sharp increase...
Memory Dominance Determines AI Compute Winners for Years
If the winners and losers in AI compute come down to who gets the most memory in the most ridiculous memory-constrained market we have ever seen.... For the next 3-4 years.... Predicting those winners is pretty easy.
Premium Pricing Ensures Big Spenders Dominate AI Landscape
One wonders if premium models/token pricing will always exist. If so, then those companies who spend the most will have distinct advantages.

Terfab Ranks Among Top Three WFE Spenders for 1GW Compute
Putting Terfab into perspective. Based on stated goals: 1GW of compute requires about 50kwpm of logic, 140kwpm of DRAM, ~30kwpm of NAND, and ~35 kwpm of CoWoS (advanced packaging). That translates to about $30bn of WFE per 1GW produced...
Anthropic Poised to Outpace Salesforce in Revenue
Seems probable that Anthropic passes Salesforce in revenue this year. I know not technically SaaS, more like intelligence as a service, but the fastest scaling enterprise software company in history is telling.
New Results Closely Match My Anthropic Model
They are tracking very closely to the model I built on Anthropic in this note. https://t.co/cspnwjWdqN

This was what I predicted. I've heard the same as well via multiple supply chain channels.
MediaTek Pushes 400G Copper Limits; Optical Next
Good discussion here on copper/optical with @mediatek. They are pushing the limits with NPC (near package copper) and CPC (co-packaged copper) at 400G per lane, with distinct efficiencies in those solutions. But past that, most likely optical NPO/CPO.

MediaTek's Flexible IP Strategy Positions It for Customer‑Owned Tooling
Being flexible, customer friendly, and willing to work with as little or as much customer owned IP the customer wants is an approach @mediatek does seem well positioned for. If you believe customer owned tooling becomes a thing. They seem competitive....

Mediatek's Custom XPU Gains Edge via TSMC Ties

Nvidia‑Marvell Tie‑up Could Lock Supply Chain via Custom XPU Racks
Per the $NVDA + $MRVL investment... I do wonder if this also opens the door to $NVDA selling CPU racks to custom XPUs made by $MRVL for hyperscale customers. Obvsiously, it does help them lock up more parts of the...
Yearly Blood Panels Enable Adaptive, Sustainable Health Tracking
This is all true. But, the blood panel (and doing that yearly) and tracking to my health metrics, and a possible nutrition data set, both things that need to adapt as you age could be a sustainable value proposition.
