Palo Alto, CA
The last time @GavinSBaker and I sat down to record a podcast, it was almost exactly a year ago and we started with the immediate question: is AI a bubble? Gavin's answer focused on utilization and returns (and perhaps unsurprisingly, his answer was: No). Unlike the dark fiber of 2000, there were, and still are, no idle GPUs. The largest buyers of compute were funding the buildout from some of the strongest balance sheets in the world, and their AI investment was already producing real returns. I sat down with Gavin again last week, and to chart just exactly where we are in the cycle. He has spent the summer asking operators for one quantitative measure in their business that is getting worse and has yet to find one. At the same time, public AI stocks have gone through meaningful drawdowns. Still, if you look at the way people are using AI today, there’s a good chance that demand diffusion has barely begun. AI revenue rests on fewer than 10m heavy users, against roughly 1.5b knowledge workers. At the most AI-native startups, token spend is approaching or exceeding 10% of human compensation, which suggests that there’s a long way to go before even the earliest adopters fully integrate agentic capabilities. Within Atreides, Gavin said token consumption rose 100x from March through August, and even further once the team started using products like GrokBot. As Gavin put it, once people begin approving automations, token consumption starts to feel “sort of endless.” This dynamic would be reason enough alone to believe that we’re massively undersupplied at the moment. But there are other reasons on the supply side too, namely that there are a near-unbounded number of potential winners in the space: - Frontier labs can keep winning because on the highest-value tasks, marginal improvements in intelligence are worth far more than marginal differences in price. - Open models illustrate that most work doesn’t require frontier performance, creating a much larger market for intelligence that is cheaper and customizable. - Nvidia, hyperscalers, neoclouds, and inference providers can simultaneously win because every additional token still requires physical compute, even if models become more efficient. - Enterprises can win as proprietary data, workflows, and institutional knowledge become more valuable. - Application companies can win by capturing services budgets and owning the customer relationship. This doesn’t suggest everyone will be successful, but it does mean the market itself is positive-sum and we will look back on zero-sum thinking as far too limiting. Better models create better products, better products create more users, more users create more token demand, and more demand supports continued investment in models and infrastructure. Check out the whole conversation below: @a16z
Gavin Baker and a16z's David George on the state of the AI boom: The future doesn't have to be winner-take-all. Labs, open-source, applications, and the clouds can all capture value. Demand for intelligence is still dramatically underestimated. Today's power users number in the millions and will grow to hundreds of millions. Gavin and David argue a compute shortage is a more real risk than an AI bubble, and building through it is an opportunity to reindustrialize America. In this episode, they get into why compute investments pay back so fast, what the data center backlash gets wrong, the case for putting compute in orbit, why enterprises will run several models at once, and how Nvidia ended up at the center of the entire supply chain. 00:00 Intro 01:06 The bear case Gavin couldn't find 05:50 Why a lab would cut its own revenue 75% 08:05 What LPs get wrong about a crash 10:50 Microsoft slowed its capex and regrets it 14:33 The engineers spending 100x the median 17:35 Why 23-year-olds use AI better than Gavin 21:45 How much copper 500M AI users need 23:00 Stop promising to cure cancer 26:00 America's richest county is full of data centers 30:48 Who gets priced out of compute 33:05 The age of Elon and Jensen 34:25 Orbital data centers 44:40 Asteroid mining 48:12 Why Microsoft doesn't need a frontier model 54:02 Who becomes the abstraction layer 55:40 Everyone wanted a deity, Cursor wanted a product 1:00:25 Never take shots at Jensen 1:07:40 What happens when the chip doesn't work 1:12:10 What chip deals reveal about customer demand YouTube: piped.video/watch?v=FGC4ofTc… @GavinSBaker @DavidGeorge83

Kevin Mandia says "There's no way to make the next year pretty." He thinks the first time a model revealed itself capable of finding thousands of vulnerabilities, is when everyone finally accepted the game has changed and AI on offense is coming. One of our most sophisticated portcos recently told us they put a significant fraction of their engineers' projects on hold and enlisted them to stress-test their own walls. Kevin's new company @ArmadinSecurity is scaling up to offer this offense-as-defense to everyone, and ultimately build out the autonomous security he believes every company will need in the AI-enabled future.
.@ArmadinSecurity is a new company that uses AI agents to attack your network before criminals do, finding real exploitable zero-days and eventually patching them autonomously. Their agents map every service, route, and system from the outside, then re-attack whenever something changes. Since January that's uncovered 90+ zero-days at Fortune 500 companies. Kevin Mandia spent 30 years responding to some of the worst breaches in the world and built Mandiant, now a core part of Google Cloud's security arm. He had no plans to start another company until AI arrived and changed everything: in his words, "everything I did is dead." He joins a16z's David George to talk about why he came back and what Armadin is building. In this conversation, they cover what AI attacks look like today, why nation states hack like a sniper and AI hacks like a drone swarm, and why the only defense fast enough to keep up is one with no humans in the loop. 1:05 "Everything I did is dead" 3:10 AI on offense, AI on defense 4:20 What an AI attack looks like today 7:20 Sniper rounds vs drone swarms 10:25 Map everything, attack what changes 14:35 The problem with pen tests 16:40 90+ zero-days at Fortune 500s 18:35 A bad patch beats an intrusion 20:55 Why humans are too slow for the SOC 24:30 Why the next year in cyber won't be pretty 26:30 How Mythos changed the threat 28:15 Caging the attacker Armadin built 30:05 Open and closed models tied on offense 34:40 AI is finding zero-days on its own 35:45 Mandiant in 2004 vs Armadin in 2026 41:20 Why Armadin retrains sales every week YouTube: piped.video/cJsHel27Z6M @ArmadinSecurity @DavidGeorge83

When people ask whether "this" or "that" will be successful in AI, the answer is very often both. OpenAI and Anthropic together represent the fastest, largest success in the history of business. They + SpaceXAI + Cursor add more revenue per month than any hyperscaler other than Amazon. Up until now, headlines like these have been driven effectively off coding applications alone. We are very early. Thank you @jaltma for having me on!
Loved the conversation on Uncapped with @DavidGeorge83, head of growth investing at a16z. He's an incredible investor and can go deep on a huge range of topics. We talked all about investing at this point in the AI cycle and we covered a lot of ground -- frontier vs. open source, what could make it all keep running vs. slow down, application vs. infra, robotics and autonomy, narrative and vibes, and lots more.

We're excited to co-lead @ArmadinSecurity's Series B. After this summer’s cyber incidents at frontier AI labs, CISOs face growing pressure to secure their companies across applications, cloud, identity, and internal networks. Armadin’s AI autonomous security platform turns offense into something defenders control, from the first Hyperattack. Built on decades of frontline adversary tradecraft, its agentic attacker swarm reasons, plans, and adapts like a real adversary. The platform learns from every attack and environment, allowing security teams to focus on fixing real problems. We believe there’s no better team to take this on than Kevin Mandia, Travis Lanham, Evan Peña, and David Slater. Kevin founded Mandiant, the firm that defined modern incident response. Kevin and the team have spent their careers staying a step ahead of attackers, and now they’re building the platform to help every security team do the same. @a16z @steph_zhang

a16z's David George, Sarah Wang, Alex Immerman, and Santiago Rodriguez on the State of Markets, from AI and infrastructure to the next investment cycles: 1. Tech is the everything cycle. High-tech equipment, software, and R&D are now about 55% of US capital spending, and the AI buildout just passed the railroads as a share of GDP. The five largest hyperscalers will spend about $780B on capex this year, heading past $1T in 2027, and demand still outstrips supply at every point in the chain. 2. It's an earnings story. Stocks are up about 20% while multiples are down about 20%, and the S&P trades under 20x earnings. The market is up 90% since ChatGPT, on 15% earnings growth. 3. AI adoption is broad and shallow. 69% of the S&P 500 has a live AI deployment, 30% report a quantified result, and just 2% have AI doing a job they'd notice if it stopped. The power users are pulling away: the top 1% of AI spenders spend eight times the top 10%. 4. The private markets are enormous. Six private companies, Anthropic, OpenAI, Databricks, Stripe, Waymo, and Revolut, add up to about $2.4T by last round, more than every IPO of the past decade combined. "The founder is the asset class. The IPO is another financing event." Plus: why a data center can lower your electricity bill, what Amazon saying no to Muse and Instacart saying yes tells you about marketplaces, and the seven areas the team is most excited about next. 0:59 Charts from State of Markets II 2:59 Tech is the everything cycle 4:56 Is it a bubble? 6:31 Hyperscaler CapEx: $1T next year 12:12 CapEx is someone else's order book 14:36 Data centers can lower your bills 17:06 OpenAI and Anthropic vs. some of the best software companies ever 18:22 Enterprise AI: 69% adopted, 2% measured 20:32 The top 1% spend 8x the top 10% on AI 24:36 Spending on AI for growth or for savings? 28:46 Only 2% of households pay for AI 31:36 Amazon blocks Muse, Instacart welcomes 36:16 Software traded growth for profit 42:56 6 startups vs. a decade of IPOs 45:46 Why employees are turning down liquidity 48:44 Seven areas they're excited about YouTube: piped.video/lr3hNhA0IfQ @DavidGeorge83 @aleximm @santiago__rdz @sarahdingwang
Introducing our State of Markets pt 2, along with a companion podcast where we unpack the data and discuss what comes next. Tech is the everything cycle. Supply: putting the buildout in context, just passed railroads as % of GDP. The wisdom of Elon is real: the factory (or the datacenter!) is the product. Demand: diffusion is so, so early. Median AI vendor spending in the top 1% of companies is 8x that of the top 10%. Only about 30% of S&P 500 companies report a quantified AI impact, which means there’s a substantial opportunity in connecting models to a company's data and workflows. Diffusion into companies is one of the main themes of the next 5 years. We’re entering the agent work period. Only a few million users today, but applicable to billions of internet users with massive surplus created. META/GOOG monetize US users at $200+ per year today. Agent opportunity is much higher. Mega-trends the next 5 years: Consumer agents, Robotics, Autonomy, AI x bio, Personal health, Diffusion into enterprise, New era of American Dynamism. Much more in our SoM report here - a16z.news/p/state-of-markets… @a16z @sarahdingwang @aleximm @santiago__rdz

Big and public used to be the same milestone. Tech IPOs at the 75th percentile enter around $3.5 billion. The ten companies here cleared it by 12-500x in private rounds. Great piece from @jkhamehl on the trillions accruing in private markets and the venture fund allocations that are still sized for the old world.

I had a great time talking with @GrantLaFontaine, who co-founded @Whatnot with @loganhead13 in 2019. What began in collectibles is now the largest live-commerce platform in North America and Europe. Whatnot reported more than $8B in 2025 GMV and says H1 2026 exceeded that total. @a16z partnered with Whatnot at the Series A. In this chat we reached all the way back to the company’s origin story (beginning with Grant selling Pokemon cards as a kid) and the larger market opportunities that lie ahead. Some takeaways: -Traditional e-commerce owes much of its efficiency to obscuring the merchant. On Whatnot, the seller has a face, a brand, and customers who return for them. Per Grant, it can be an advantage to lack experience in an established category: instead of copying what exists, you focus on the experience users want. When Whatnot was getting started, lots of teams were trying to emulate the live shopping marketplaces growing popular in China. Instead of doing this, Grant and Logan just tried to make the best place to sell collectibles. -Whatnot feels more like entering a store or mall than querying a product catalog. The buyer may know the kind of thing she wants, but the exact purchase emerges from browsing and entertainment. Live formats make expertise valuable. A seafood distributor can show what came off the dock, explain why it is in season, answer questions, and reach buyers nationwide. -Today, people spend ~95 minutes a day on Whatnot, and on a given day more than 80% of them don't buy anything. "It's because it's fun. If you simplify Whatnot down, the buyer value prop is a fun experience to shop, and there's not a whole lot of fun experiences shopping online." -When it comes to using AI, the company wants to empower their sellers. Whatnot uses LLMs to infer listing metadata and provide business insights while preserving the seller relationship that brings customers back. A fun conversation about marketplaces creating new demand, new sellers, and entirely new businesses.
In third grade, Grant LaFontaine sold a Pokemon card online. The buyer mailed a money order; Grant cashed it at the post office and then shipped the card to the customer. Today he's co-founder and CEO of @Whatnot, where the largest businesses do over $100 million a year at up to 40% margins. Grant joins a16z's David George to discuss how that first transaction became a platform that did $8 billion in sales last year, why live commerce is a third of all commerce in China yet still emerging in the US, and how Whatnot operates reliably at scale, and more. 00:00 Intro 01:05 The Pokemon card and the money order 06:25 Half a Bitcoin for a domain 09:20 Why not knowing the market was an advantage 11:05 Customers don't care about your market 12:45 Most people don't buy anything 17:15 Why the eBay comparison misses 20:05 95 minutes a day on a shopping app 25:00 Sellers doing $100M with 40% margins 26:35 Fresh fish from the San Diego dock 32:25 Running a police force for two New York Cities 37:00 Why Whatnot won't do AI avatars 40:15 Cars on Whatnot @GrantLaFontaine @DavidGeorge83

Congratulations to @OpenRouter and @stripe! This is a massive win-win. Here is @gaybrick talking about the movement between tokens and dollars. Also, Late Stage Venture is about Late Stage Founders 🤝 "Deft Helmsmanship" @a16z
OpenRouter is joining Stripe: stripe.com/newsroom/news/str…. As anyone who uses it knows, @OpenRouter is a truly delightful developer tool. It is by far the best way to use new models and manage multiple inference providers. OpenRouter is also playing an increasingly important role: in the future, every business will have to manage both revenue flows and token flows. OpenRouter is the world's leading token marketplace, helping businesses effectively allocate the new currency of intelligence capital. We think that there's a lot to build together.

Stripe’s strategy is to “win all the startups and then win them again.” I had a great time talking with @gaybrick. Will has held a broad seat at @stripe for more than a decade, joining as CFO in 2015, and today leading Technology and Business. This makes him the right person to explain how Stripe went from a simple payments API to a platform with ~25-30 banner products and 288 launches at its most recent Sessions event. Here’s what their strategy looks like: -Companies like DoorDash and Instacart started on Stripe when they were tiny and pulled the company upmarket as they expanded. -The fastest startups act as canaries for new product opportunities. Cursor surfaced a burgeoning problem of AI free-trial and token abuse; so Stripe built a token detection pipeline with the team in a weekend, and the resulting network now helps companies on Stripe’s platform block thousands of fraudulent trials daily. -Stripe keeps expanding the number of needs it serves inside each company, from Billing, Radar, and Tax to Managed Payments, Treasury, and stablecoin infrastructure. There is a large and timely lesson from Stripe which I strongly agree with: using AI solely to reduce cost is essentially going short your own company. Instead, companies should be using AI (and the tailwinds it creates) to ship more, serve users better, and create their next product line. And as Stripe continues to invest in agentic commerce, the company can move from processing a transaction to orchestrating the entire economic loop around it. The line between tokens and dollars is already blurring, and Stripe’s next mandate is to make moving between them as seamless and safe as moving between dollars and euros. A fun conversation about what it takes to build the next Stripe inside Stripe. @a16z
Stripe's Will Gaybrick: "Build everything" Against an industry that sees agents as a way to cut costs, Stripe is using them to build more: agents wrote 30% of code in a week, global tax filing shipped in 1/3 the time the US version took, and after AI made sellers 20% more productive, Stripe hired even more sellers. President of Technology & Business @gaybrick sits down with a16z's David George to cover why there's no one left for Stripe to copy, why checkout pages will disappear, how agents plus stablecoins make micropayments real, and why tokens are becoming a currency worth protecting like dollars. 00:00 Intro 01:00 From payments to 30 products 02:30 1 in 6 free trials abused 05:50 Win the startups, then win them again 09:40 Borrowing from Google, Apple, and Ford 14:30 Minions: 7K one-shot PRs a week 18:45 Building everything vs. cutting costs 26:00 Why timelines keep compressing 29:50 What replaces the checkout page 34:20 The case against $9.99 subscriptions 37:20 Stablecoins solve a political problem 41:35 Tempo, a payments-only blockchain 43:10 Tokens are money now 49:00 How Stripe scales taste piped.video/watch?v=P5iICDVn… @gaybrick @DavidGeorge83
