Coatue founder Philippe Laffont says in a video clip posted on X on 8 November 2026 by the account Fireside Tapes: “If you think that now the new BFI is OpenAI and Anthropic, then go figure out what hangs off BFI, what hangs over Anthropic and OpenAI”.
Laffont explains the term in the clip: “you only need a few ideas and we call them BFI”, with B for big and I for idea. Laffont says that “recently, the BFI was NVIDIA”.
Business Pill · Concentration Explained
A short Business Engineer explainer on concentration, when much of a market depends on a few companies. It teaches the general idea only and does not discuss Coatue or Laffont.
The key insight: Coatue founder Philippe Laffont says in a clip posted on X on 8 November 2026 that the new BFI, the big idea a technology wave hangs on, is OpenAI and Anthropic, a role Laffont says Nvidia recently held. Laffont tells investors to work out what hangs off the two labs, as Nvidia’s need for DRAM and flash memory once showed.
Laffont describes how the Nvidia idea worked as a map: “once you figured out NVIDIA, you could figure out the supply chain. Then you figured out that NVIDIA was going to need DRAM memory, then flash memory”.
Laffont compares a big idea to “a grove of aspen trees”, where the stocks are the trees and “there’s this one root that connects all these trees together”. Laffont says that “in each wave, you only need like one or two or three BFIs over 10 years”.
Laffont then lists earlier waves: “Back in the age of the PC, it was Wintel”; “In the age of the internet, it was Google and Facebook and Amazon”; and in the cloud, “it was Azure, which belongs to Microsoft. It was AWS that belongs to Amazon”. By our count, the clip names three waves before the one Laffont now places on OpenAI and Anthropic: the PC, the internet and the cloud.
On Coatue’s own record, Laffont says: “I missed the cloud wave. And for two or three years, we did really poorly”. Laffont adds that the lesson was that it is “never too late to change waves”.

What Was Posted on X
Philippe Laffont explains how Coatue hunts for the one big idea behind each technology wave
“So we have this concept in the investment world that you don’t need a lot of ideas. And in fact, you only need a few ideas and we call them BFI. And B stands for big, I stands for idea and F stands for, well, you can figure out what the F stands for, right? So you got these big, big ideas, BFIs. And in each wave, you only need like one or two or three BFIs over 10 years.”
“And the BFI, it’s like almost like the grove. And then that’s the BFI, the theme, the BFI is like a grove of aspen trees. And then the stocks are like trees, but all those, I forgot if it’s the aspen or no, that they’re all connected to this one root. And there’s this one root that connects all these trees together.”
“And I always felt so, if you think about it, recently, the BFI was NVIDIA. And once you figured out NVIDIA, you could figure out the supply chain. Then you figured out that NVIDIA was going to need DRAM memory, then flash memory, and then blah, blah, blah. And that was the idea, right? If you think that now the new BFI is OpenAI and Anthropic, then go figure out what hangs off BFI, what hangs over Anthropic and OpenAI.”
“Back in the age of the PC, it was Wintel. It was Microsoft and Windows and Dell, right? In the age of the internet, it was Google and Facebook and Amazon, right? In the age of cloud, it turns out that it was Azure, which belongs to Microsoft. It was AWS that belongs to Amazon. So interesting, some companies have a foot on one wave and then find a way to surf the other wave. And then some companies, they f**k up. And there’s usually cultural reasons. Like you could say maybe IBM, they were at the pinnacle with the mainframe and the PC. But somehow they were not able to transition to the age of the internet, to the age of cloud and things like that. And now it’s not the same company it used to be, right?”
“So I also think like it’s important. That’s why I try sometimes to pivot and stuff. But it’s like you’re surfing these waves and you’ve got to sometimes say, this is a good wave and I can surf it for 10 years. But sometimes there’s this one junction where you guys say, I got to get off this wave and get on that wave. And sometimes I’ve managed to do that. And then one time I totally missed the wave and I missed the cloud wave. And for two or three years, we did really poorly. And in retrospect, what I’ve learned from this is never too late to change waves and every day is a new day.”
The Fireside Tapes account posted this clip of Coatue founder Philippe Laffont on 8 November 2026, with a transcript in the post. The quotations in this piece are taken from that transcript.
What Hangs Off OpenAI and Anthropic
Laffont does not list the companies in the clip. Our earlier coverage shows parts of the chain. On the memory link Laffont names for Nvidia, Micron’s shares were up 142% this year, as reported on 8 November 2026 in Micron Is Up 142% This Year; Four Hyperscalers Average 1.4%.
As we read the clip, Laffont is describing a research method rather than naming trades: start from the one company a wave depends on, then work outward to its suppliers.
As we read the Nvidia example, the method put memory makers on the map because Nvidia was going to need DRAM and flash, in Laffont’s words.
As we read the comparison, Laffont moves the root of the map from a chip maker to two model labs, which places their chips, power and financing at the next ring out.

“If you think that now the new BFI is OpenAI and Anthropic, then go figure out what hangs off BFI, what hangs over Anthropic and OpenAI.”
Three Implications
FOR INVESTORS Laffont says each wave needs only one, two or three BFIs over 10 years, and that the stocks connect to one root.
FOR SUPPLIERS TO THE LABS Laffont’s framing points attention at what hangs off OpenAI and Anthropic, as memory once hung off Nvidia.
FOR FUND MANAGERS Laffont says Coatue missed the cloud wave and did poorly for two or three years, and that it is never too late to change waves.
The analysis says: “It is a layered industrial stack — and at any given moment, the binding constraint sits at a different layer than it did six months ago.”
As we read it, Laffont’s BFI method walks the same stack outward from one root. The analysis predates the clip and does not discuss Coatue.
What Is Not Established
The clip does not say when or where Laffont spoke, and we could not confirm the original interview. Laffont does not name any stock, position or Coatue holding tied to OpenAI or Anthropic in the clip. The post is not a Coatue filing or a fund letter.
This Week In The AI Supercycle
The Great Convergence of Capital, Power, and Geopolitics
This week’s issue: for two years the AI build-out was priced as a supply story, and last week as a credit story. This week it was priced as a permission story, and the answer arrived as a cost, not a ban.
In a clip posted on 8 November 2026, Laffont calls OpenAI and Anthropic the new BFI, the role Laffont says Nvidia held, and tells investors to work out what hangs off the two labs, as Nvidia’s need for DRAM and flash once showed. By our count it is the fourth wave the clip names, after the PC, the internet and the cloud.
A note on sourcing. Quotations are Philippe Laffont’s words as transcribed in the Fireside Tapes post on X of 8 November 2026, read on 9 November 2026. We could not confirm the original interview and did not contact Coatue. The wave count and the chain mapping are ours.
