Cahn: Chip makers finance AI buildouts to book revenue circularly
“The chip companies are now stepping up and saying, okay, we'll absorb some of the risk. We'll put in the capital to finance this build out where the demand on the other side is not so clear because of course the chip companies also get to book this as revenue.”
Cahn: Any AI bubble unwind will hit household stock portfolios, not banks
“What I think is going to be interesting if to the extent that the bubble unwinds at some point, it's going to be an equity unwind. And what that looks like is 40% of the S&P 500 is basically a bet on AI. And so to the extent that the bet unwinds, stock prices …”
Cahn: Venture capital firms cannot 'king-make' startups with capital alone
“I don't believe in King making and that's maybe a controversial thing to say. I think one of the lessons, you know, you'd think like, oh, Sequoia should be able to King make companies and like, that's so great. And that would be, by the way, if that was true, …”
Cahn: AI startups will win by hiring 23-to-25-year-old AI generalists
“I think that the new playbook for these AI startups is actually going to be much more about hire the AI generalist, this 23, 24, 25 year old who's really native in AI, really passionate about it, and I think those are the sort of the front lines that are going…”
Cahn: Current AI Products Are Not Yet Showing Strong Value Creation
“The burden to deliver value is very, very high in business. And we're not seeing that so strongly in AI yet.”
Cahn: AGI Is Decades Away and Not Happening Anytime Soon
“It's like, we're probably gonna be fine. AI is probably gonna change our lives and make it better. It's gonna improve productivity. Maybe AGI is gonna happen when you and I are like, 90, but I don't think AGI is happening like tomorrow.”
Cahn: Generating $1B+ Gains Is the Only Definition of Success in VC
“There is a definition of success in this business. You're either a slugger or you are not. If you are generating billion dollar gains, you are a slugger. Doug Leone is a slugger. Pat Grady is a slugger. And Jurita is a slugger, right? So you either are sluggin…”
Cahn: Founders Should Offer Up to 5% Equity for Transformational Hires
“I tell founders all the time, if you find someone who's going to transform your business, give them five percent of the company. Now I say that it's an extreme statement. Maybe it's four percent, maybe it's three percent. But I think we get very married to lik…”
Cahn: ChatGPT Is Now a $3.4 Billion Revenue Business
“Definitely OpenAI. I mean, OpenAI has a brand, it has consumer distribution, it has product market fit with ChatGBT, which is a 3.4 billion dollar revenue business now. I think ChatGBT will definitely be around. Yeah, I think a bunch of the others will too for…”
Cahn: AI infrastructure investment requires $840B in end-user revenue
“If you invest one hundred fifty billion in NVIDIA chips, that's about three hundred billion of data center investments. And to pay that back, the person using the compute needs to earn a 50% gross margin. So there's about six hundred billion of revenue that ne…”
Cahn: Whether real end-user demand exists for AI compute remains unanswered
“Is there actually an end user for this compute? I don't think that's been answered.”
David Cahn: AI industry is at the start of data center construction delays
“One of the predictions I made last year, in addition to saying it was going to be the year of the data center in 20, 25, I said, Hey, we're going to have these construction delays. We're going to have issues now in building out these data centers. And the info…”
David Cahn: Physical data center construction capability will be a competitive moat
“One of my core perspectives that I've been developing over the last 18 months of writing about this is that construction itself is going to be a moat. The ability to build things is hard. And I think we underestimate that.”
Cahn: Top AI researchers command $50M to $1B compensation packages
“If you're a 25 year old recent grad from an elite university who is perceived to be an AI expert, you can get a fifty hundred million dollar pay package right now. And if you are a brand name that everyone recognizes your name, you can get a billion dollar pay…”
Cahn: Enormous AI compensation packages reflect desperation to prove investment ROI
“I think they're symbolic of this sort of desperation in the ecosystem where it's like, we need to eke out progress. We need to prove that all these investments are worth it.”
Cahn: Investors overestimate how much individual researchers drive AI progress
“That said, I think we are psychologically biased to overestimate what that percent contribution is. And it may be the case that there's these broader macro variables, which we'll talk about, I'm sure later in this discussion, there's these broader macro variab…”
Cahn: Meta's $100M AI packages stem from underperformance
“And I think that Meta, you know, these hundred million packages are coming in large part from Meta because they haven't performed as well as they thought they were going to.”
Cahn: Competitive pressures will force all AI model providers to vertically integrate
“I think that competitive pressures will push all of the model providers to spend more time on this and to have teams focused on this. So I think the answer is yes. I do think that this is a trend that is going to be durable.”
Cahn: Compute-consuming AI products will outperform compute producers long-term
“So I think if you're a producer of compute, you're fundamentally in a commodity business, just like an oil company is in a commodity business, and that is going to trade a different way, and that is going to have more cyclicality than if you're in a non-commod…”
David Cahn: AI Era Competition Will Prevent Monopoly Profits
“The difference is that these monopolies are not hiding in plain sight. We all now know that if you build an amazing tech company, it can be worth a trillion dollars. In 2000, if you told people that they can have a trillion dollar tech company, they would have…”
Cahn: Over 80% of AI venture capital goes to compute producers
“And I think probably 80% plus of the dollars in AI are still going to producers of compute. Not consumers of compute.”
Cahn: Big Tech AI spending will not stop without incentive changes
“And so I think until the incentives change, the behavior is not going to change. And so there is no coordinating mechanism.”
Cahn: Microsoft walked away from two data centers in early 2025
“Microsoft walked away from two data centers and it sent a message to the market like, hey, we're not stepping up.”
Cahn: AI infrastructure build-out is mostly equity and cash funded
“I actually think that what's interesting about this AI build out is that for the most part, and let's put Oracle aside, which maybe has some debt, but for the most part, the AI build out today has been equity funded and cash funded.”
Cahn: The AI timeline is the most overestimated factor in tech
“I think that we are, I think there's a number of things that are over being overestimated. I think the most important one is the timeline.”
Cahn: AI newcomers expect immediate AGI while pioneers project long timelines
“Like the path we're on was invented by these people who are raising the most concern or saying the timeline is longest. And it's the people who've been in AI the shortest who I think are saying like, Hey, it's going to come tomorrow.”
Cahn: Overanalyzing gross margins can impede venture capital returns
“At the end of the day, our job is to invest in companies that become really successful, not to be like super smart about analyzing them. And so I think sometimes the instinct to criticize a gross margin can get in the way of money making.”
Cahn: AI gives junior startup hires near-parity with senior peers
“Maybe 10 years ago, if you joined a startup and people didn't join startups that often, 10 years ago, maybe 10 years ago, if you joined a startup, like there's this whole experience curve, you're the junior engineer. There's a lot of people who are smarter tha…”
Cahn: Defense technology is the next AI-scale investment opportunity
“I would say, and I think this ties into our conversation so far, that AI, that defense is the next AI.”
Cahn: Defense tech is under-hyped and awaiting its ChatGPT moment
“And so, anyways, I think that the Transformer paper moment was the was the Ukraine war, and then I think the Chi-GPT moment hasn't happened yet. And so I think that defense is actually, you know, is under-hyped in some ways, or like underestimated in some ways”
Cahn: Defense Tech Adoption Cycle Is Only 1% Complete
“We're like one percent there on catching up. Like we're actually so, so early in this defense cycle because, you know, now we have a few dozen companies, maybe a hundred companies that have sort of new innovations. They're not integrated into the force structu…”
Cahn: Few concentrated defense tech winners will emerge per country
“And I guess my framework, and this is the thesis that I've been investing behind now for the last couple of years is my framework is there are going to be fewer companies that succeed in defense for this reason. Defense is consolidated for good reason. There's…”
Cahn: Anduril is clearly the US national champion in defense tech
“And in my view, Andrew is clearly the national champion in the U S and credit to that team, just really phenomenal company, phenomenal visionaries.”
Cahn: People will talk to and form relationships with AI within 10 years
“I think the idea that we're going to be sitting here in 10 years talking to our AI, having a relationship with our AI, I think that's very likely, and I think it's a little bit sci-fi right now and I think it's going to get less so in the coming years.”
Cahn: No AI Lab Will Train Frontier Models in the Same Data Center Twice
“No one's ever going to train a frontier model on the same data center twice, because by the time you've trained it, the GPUs will be outdated, and the data center will be too small.”
Cahn: AI Capital Expenditures Over Next 24 Months May Be Hard to Repay
“Believing in AI and believing that infinite capex in the next two years, those are very different concepts. You can believe in AI, but also believe that the amount of capex in the next 24 months may be difficult to pay back.”
Cahn: Big Tech AI Spending Is Speculative, Not a Guarantee of Revenue
“The wrong takeaway is, oh, Google knows something we don't know, and therefore is making this investment, and therefore hundreds of billions of dollars of AI revenue are guaranteed in the next two years. That's the extrapolation I think people were making that…”
Cahn: Big Tech's Overproduction of Compute Directly Boosts Startup Gross Margins
“These big tech companies are producers of compute. Startups are consumers of compute. So if you believe there is an overproduction of compute and that compute prices go down, startups win because they are buying those compute. Lower cost of compute directly tr…”
Cahn: Researcher Mobility Has Eliminated Differentiation Between Top AI Models
“All these researchers, they jump from one lab to the other. It's not like there's that much differentiation anymore between the actual models that these companies are launching.”
Cahn: Injecting AI for Marketing Adds Costs Without Pricing Power
“If you are simply injecting AI so that you can tell investors that you have AI and so that you can, you know, talk on your marketing page about how you have AI, then you're just injecting a new cost item with actually no benefit to the consumer. And if there's…”
Cahn: AI Features Will Not Create Pricing Power for Weak Software Businesses
“If you had pricing power before AI, you'll have pricing power after AI. If you didn't have pricing power before AI, you probably won't have pricing power after AI.”
David Cahn: Nvidia CEO Jensen Huang is the Steve Jobs of our era
“Jensen is the Steve Jobs of our era.”
Cahn: Separate Data Center and AI Model Teams Will Fail as Models Scale
“I think the vertical integration piece is gonna matter in the sense of you can't have a separate team running the data center and a separate team building the model. That is just not gonna work as these models get bigger and bigger. You need to deeply couple t…”
Cahn: Competing in Frontier AI Requires a Massive Non-AI Cash Machine
“I think the evidence of the last couple of years is in order to play in the big model game, you need a cash machine and that cash machine cannot be the AI business, right?”
Cahn: No Major AI Model Company Holds a Data or Compute Advantage
“I think it's really hard to argue today that any of the big model companies has a data advantage. Compute, it's just a commodity that you pay for. So it's hard to argue that any of them has a compute advantage.”
