The AI Semiconductor Boom and What Could End It with Stacy Rasgon | The Real Eisman Playbook Ep 63
The Real Eisman Playbook
· · Hosts: Steve Eisman · Guests: Stacy Rasgon
Summary
Stacy Rasgon argues that semiconductors have become the market’s center of gravity because AI infrastructure is now pulling almost every chip category higher. He says the rally has broadened from Nvidia and Broadcom into memory, semicap equipment, optical, power, and CPUs, and that the sector’s big year-to-date gain has mostly been driven by earnings growth rather than multiple expansion. In his view, the key question is not whether stocks are expensive, but whether AI-driven earnings can keep compounding at this pace.
On Nvidia, Rasgon says the company is still growing extremely fast and has improved disclosure around customer concentration, showing data center revenue split roughly 50/50 between hyperscalers and everyone else. He also says Nvidia’s new CPU story matters because agentic AI should increase CPU content per workload, even if the simple attach-rate model is imperfect. He pushes back on Michael Burry’s depreciation argument, saying older GPUs remain economically useful and rental prices are rising, not falling.
Rasgon is constructive on AMD because its server CPU share has risen sharply and its GPU deals with OpenAI and Meta could help it build an ecosystem, even if the warrants in those deals are expensive. He is also more positive on Intel than he used to be because of better narrative momentum, balance-sheet cleanup, packaging demand, and government support. Broadcom, Qualcomm, ASML, Lam Research, and KLA all remain leveraged to the same AI buildout, with Broadcom’s AI networking and custom-chip guide especially large relative to the company’s historical scale.
Key takeaways
- Rasgon says the semiconductor rally has spread from compute to memory, semicap, optical, power, and CPUs because AI keeps creating new bottlenecks.
- He says Nvidia’s data center revenue is about 50/50 hyperscalers versus non-hyperscalers, reducing some customer-concentration fear.
- Rasgon argues Burry’s depreciation bear case is weak because older Nvidia GPUs are still rentable and economically viable.
- He says AMD’s server CPU share has climbed from about 0.1% in 2015 to the low-to-mid 40s today, and its GPU deals are scaling the ecosystem.
- He says Intel’s narrative has improved on better execution, packaging demand, and political support, even though its products still lag competitively.
- Rasgon says the main derailment risk is not valuation but a collapse in AI return on capital that would force capex cuts across the ecosystem.
Notable quotes
“The center of the universe right now is semiconductor and semiconductor equipment companies because that is where the entire AI infrastructure is being built out”
“AI has gotten so big, it is now dragging everything along with it”
“the revenue growth was 85% and two quarters ago was 65%. It's actually accelerating”
How the episode opens
Hi, this is Steve Eisman. You know, in the great financial crisis, people sometimes ask me, why did I foresee what was going to happen? And the answer in some ways is that the center of the univer universe back then was the entire financial sector and that was my area of expertise.
So, I knew what was going on. The financial sector has not been the center of the universe for a very very long time. The center of the universe right now is semiconductor and semiconductor equipment companies because that is where the entire AI infrastructure is being built out.
And so today we're going to talk to a recurring guest, Stacy Rasgen of Bernstein, who covers semiconductors and semiconductor equipment companies. And we're going to discuss what's going on, why it's going on, and what could possibly derail it. And afterwards, I'll be back with some closing thoughts.
Hey, this is Steve Eisman and welcome to another episode of The Real Eyesman Playbook. And today we're going to discuss a group that I would say is the center of the universe right now, which is semiconductors and semiconductor equipment companies. We're going to talk about it with a recurring guest now, Stacy Rasgen of Bernstein, who we spoke to
Maybe seven months ago. — Seven Seven months ago. Stacey, welcome. — Good to be here. — So, Stacey, you are the center of the universe. How does that feel? — Like, it's semis are always interesting. There's always something going on. Um, — Maybe. So, but you've never been the center of the universe.
It is nice to be popular. Like, I'll I'll I'll I'll leave it at that. I always joke, — You know, I I do I do well at at Bernstein.
