    AI Bubble: a16z Says No. So Who's Left Holding It?

    Click here to watch a video of this episode. Andreessen Horowitz has published 90 slides arguing that AI is not a bubble, one month after closing a $1.1 billion fund for AI hardware. On slide 88, holographic Pokémon cards are up 110% since January 2024, against 72% for the Nasdaq. The real question is not whether there is an AI bubble, but who is holding it when the next buyer pauses. On 30 September, a16z's Growth team, led by David George, published State of Markets II. The deck makes a serious case: tech delivered about 76% of the S&P 500's earnings growth this year, and valuations fell while profits rose. The twist is in the financing. Meta's Hyperion data centre sits in a vehicle 80% owned by Blue Owl's funds, the Chicago Fed puts large US banks' committed AI-related lines at about a quarter of their core capital, and the AI bubble debate has quietly moved from shareholders to banks, insurers and pension funds. Aman Narain and Zubin Vandrevala boil the deck down to five mega trends and ten takeaways for financial services, score every argument, and walk through, day by day, what happens if the AI bubble bursts. Key takeaways:1. a16z is right about the companies and silent on who pays for them: in one quarter Alphabet and Amazon booked about $150 billion of paper gains on private AI stakes, roughly 12% of S&P 500 earnings on Goldman's estimate.2. Finance has become the balance sheet of AI: Meta's Hyperion data centre sits in a vehicle 80% owned by Blue Owl's funds, with about $27 billion of bonds behind it and Meta as the tenant.3. The Chicago Fed puts large US banks' drawn AI-related loans at about 9% of Tier 1 capital and committed lines at about 25%. The gap is what nobody sees until a bad week.4. AI efficiency is real and gets competed away. The saving goes to the customer, and part of the AI budget comes straight out of headcount.5. If the AI bubble bursts, pensions and insurers face a markdown rather than a wipe-out. The danger is that every loss arrives in the same week. Topics covered:- Why a16z's deck deserves both respect and a disclaimer: the umbrella seller's weather forecast- Five mega trends, argued both ways and scored: earnings, capex, atoms, cheap intelligence, private markets- The merry-go-round between cloud giants, AI labs and lenders- Linda in Loudoun County, and what data centres do to a household electricity bill- How Meta rents its own Hyperion data centre, and why Steve Eisman reaches for Enron- Graham's pension: one capex cycle in four wrappers- Chip-backed loans, data-centre securitisations and a CDO question from London in 2000- Fintech funding splitting in two: Stripe and Revolut, then everyone else- Agentic payments: machines paying machines before consumers do- What happens to pensions and life insurance if the AI bubble bursts, and the likelier plateau- Four dated predictions, to be checked on 6 October 2027 Chapters: (00:00) - Cold open: Pokémon cards beat the Nasdaq (00:53) - San Francisco to Vegas: Metallica, then Money20/20 (01:39) - Singapore: fintech, fatherhood and F1 (02:16) - A confession: the one thing we got wrong (02:56) - Meeker, Evans and a16z's 90 slides (03:29) - Disclaimer (03:49) - A weather forecast from a man selling umbrellas (04:37) - Five mega trends, ten takeaways, one cauldron (05:15) - Mega trend 1: profits are outrunning prices (05:55) - A snake eating its own tail: $99bn of paper gains (06:53) - Mega trend 2: $780 billion of capex, on credit (07:58) - The merry-go-round and the three witches (09:06) - Mega trend 3: "Atoms are so back" (09:48) - Linda in Loudoun County: the $14 to $37 bill (10:40) - The GPUs arrive on time.

    S2E28 — Is This the Start of a Revolut-ion? Inside the Rise of Nik Storonsky's $115bn Bank

    Click here to watch a video of this episode. Revolut is valued at $115 billion, holds more than £50 billion of customer money, and lends out about £2 billion of it. What does a bank that refuses to lend actually do with a deposit, and what happens when the man who built it is the only part that cannot be automated? In September Nik Storonsky won conditional approval from the OCC to form Revolut Bank US, sat down with the Banque de France in a black suit and a red tie, and watched two data breaches reach Revolut customers inside a fortnight. The founder who spent years being publicly rude about regulators is now dressing for them, and for the investors who will price a Revolut listing at up to $200 billion. Aman Narain and Zubin Vandrevala trace Storonsky from Dolgoprudny and the Lehman trading floor to the Revolut of today, and ask whether he has built anything that works when he is not in the room. Key takeaways:1. Revolut's scar is Lehman, not Moscow: it lends under 5p of every deposit pound, where Nubank lends roughly 58p.2. Nubank, Revolut and SoFi run the same flywheel but answer one question differently: a deposit is for credit, for float, or for software.3. Removing credit risk bought rate risk. When rates fall the float shrinks, as Wise has already shown.4. Citi, HSBC and Standard Chartered retreating as Revolut advances is one spreadsheet read from opposite ends.5. Storonsky took judgment out of lending, hiring and investing, and kept all of it in one room: his own. Topics covered:- Dolgoprudny, the 1998 default, Phystech and the Lehman floor on 15 September 2008- A sub-5% loan-to-deposit ratio, the contested 40-50% return on equity, and the ECB's 4.5% capital add-on- Nubank, Revolut and SoFi: one flywheel, three ladders- Mexico's 15% savings rate, and the rate risk inside the float- Forty direct reports, Karma scores and five risk chiefs in seven years- Revolut Pay, Spanish ATMs, a £500,000 private bank, Revolut People and AIR- John Reed's Citi, success transfer, and the incumbents' retreat from retail- Ports versus platforms, and why Durbin may tax the US charter- The case against: fines, a secret ECB freeze, two breaches and sanctions- The IPO test, and two closing wagers Chapters: (00:00) - Cold open: Nik Storonsky's suit, Washington, April 2026 (01:09) - A risk episode, and the suit is the tell (01:39) - Zuckerberg's hoodie, and a tie for the central bank (02:42) - Disclaimer (03:31) - Dolgoprudny, 1984: a company town for physicists (04:54) - Two currency collapses before he turned fourteen (05:42) - The childhood hypothesis versus the trader's arbitrage (06:19) - Phystech: raw brain power, then character, then craft (06:59) - Lehman, 25 Bank Street, 15 September 2008 (08:12) - Credit Suisse, and his one rule on complex risk (08:56) - Six pence in every pound: the bank that won't lend (09:41) - The 40-50% return on equity claim, audited (10:24) - Zero risk weights and the ECB's 4.5% add-on (11:35) - Nubank vs Revolut: same flywheel, opposite ladders (13:27) - SoFi's third ladder: renting out the crown jewels (14:02) - What is a deposit for? Credit, float or software (14:50) - Mexico's 15% savings rate is a marketing budget (16:06) - The float's weather problem: rate cuts and Wise (17:02) - Inside the building: forty direct reports (17:43) - Jensen Huang's sixty, and the span-of-control question (19:36) - Karma: compliance priced into the bonus (21:06) - Hiring as a live exam, and millionaires in Krakow (22:08) - Five chief risk officers in seven years (22:34) - A different clock speed: 80 million customers (23:46) - Revolut Pay: an ad network with a checkout attached (25:01) - He built ATMs: Barcelona, Madrid, Milan (26:14) - Branches as billboards, and a £500,000 private bank (26:38) - Revolut People: the HR department became a product (27:35) - AIR: when super-app clutter becomes a moat (29:39) - The day the assistant moves money (29:56) - QuantumLight: taking judgment out of capital (31:04) - Risk doesn't vanish, it conserves (31:15) - Canary Wharf: Reuters, HSBC and Lehman in one view (32:20) - The oldest ambition in banking: to be everywhere (32:52) - John Reed, 1977: Citi builds its own ATMs (34:22) - Success transfer: Citigold, forty years early (35:17) - Nostalgia is not a strategy: the incumbents retreat (36:45) - Forty countries live, a hundred targeted (37:41) - Same spreadsheet, read from opposite ends (38:50) - They banked ports, he banks a platform (40:08) - Durbin: the US charter that may cost interchange (40:54) - A wager: will Revolut exit a country before 100?

(01:00:47) - Has he built anything that works without him?

    $2 Trillion U-Turn: Did AI Just Grow a Conscience?

    Click here to watch a video of this episode. In seventy-two hours the AI industry asked to slow down, OpenAI shelved a trillion-dollar listing, and the President called the whole thing a hoax on speakerphone. Everyone called it the week AI flip-flopped; nobody did, and one supplier gets paid either way. On Saturday 12 September, Anthropic chief executive Dario Amodei published We Must Pace the Frontier, a call for an AI slowdown in how fast frontier models gain capability. Within hours Elon Musk replied "Dario is right" and Sam Altman told Fortune there would be no OpenAI IPO this year. By Monday, President Trump had called AI fears a hoax and phoned Jensen Huang live at the All-In Summit. The twist: the call for an AI slowdown came in the same quarter Anthropic booked $11.5 billion of revenue and positive adjusted operating profit. Aman Narain, solo this week while Zubin Vandrevala is in London, breaks down who actually wants an AI slowdown, who only says so, and who gets paid whichever way it goes. Key takeaways:1. Almost nobody changed position this week. What changed is which kind of doom each player chose to say out loud.2. Read the capex, the PAC cheques and the IPO calendar: what AI leaders say moves weekly, what they spend does not.3. The call for an AI slowdown arrived in the quarter Anthropic proved the frontier pays.4. Pacing is not stopping. In a boom Nvidia sells the training, in a slowdown it sells the testing, and inference carries on regardless.5. The doom that decides the US midterms is not extinction. It is the electricity bill of a voter who lives near a data centre. Topics covered:- Five things in fourteen days: escaped agents, a resignation, Nvidia buying Hugging Face, the essay, the speakerphone- A four-box map: AGI believers and sceptics, accelerators and restrainers, and the two people who move- Three dooms and two booms: extinction, displacement and deflation against capability and capital- Say versus pay: Sam Altman's four positions in eleven years- David Sacks's cartel charge, Jensen Huang's inspectors, and 100 gigawatts of physics- The circular trade: Nvidia's equity in its customers, and the Lucent precedent- Why an AI slowdown does not shrink Nvidia's order book- Data centres, power bills and the midterms- China: invoked everywhere, included nowhere- Four calls for 2026, including where Anthropic's IPO prices- Closing wagers: prophet or cynic? Chapters: (00:00) - Cold open: $2 trillion changes its mind (01:06) - Disclaimer (01:21) - Five things, fourteen days: agents slip the harness (01:48) - 150 million views and "Jacob is correct" (02:58) - Nvidia buys the platform that got attacked (03:15) - From Machines of Loving Grace to Pace the Frontier (04:22) - "Dario is right": Musk, Altman and a shelved IPO (04:46) - Whoever wins AI wins: the President on speakerphone (05:20) - The map: three dooms, two booms (06:29) - Who sits where, and the two who move (07:33) - Say versus pay: Altman's four positions (08:37) - $11.5 billion: pacing arrives the day it pays (09:52) - Going around the table: Sacks calls it a cartel (10:45) - Inspectors with staff badges (11:29) - 100 gigawatts: why the frontier was slowing anyway (12:01) - The circular trade: Nvidia's $50 billion loop (12:38) - We've seen this film: Lucent, Nortel, $8.1 billion (13:12) - Same machine, quieter number: the capex clock (13:44) - Two invoices from the same supplier (14:26) - The doom that votes: a retired teacher in Ohio (16:17) - China: invoked everywhere, included nowhere (18:21) - Four calls: Anthropic lists, OpenAI waits (18:58) - Damodaran's $1.2 trillion hurdle (19:34) - Concorde versus the 747 (19:57) - The midterms: her bill is the ballot paper (21:16) - Closing wagers: prophet or cynic? (23:01) - Doom is a language, capex is a fact (23:45) - Kierkegaard and the dizziness of freedom Referenced in this episode: Dario Amodei, We Must Pace the Frontier; Dario Amodei, Machines of Loving Grace; Jacob Coxon's resignation and Evan Hubinger's reply; Nvidia's $12.93bn agreement to acquire Hugging Face; Sam Altman's Fortune interview; the All-In Summit call between President Trump and Jensen Huang; Anthropic and OpenAI Q2 2026 results as reported by the FT, CNBC and WSJ; Aswath Damodaran on Anthropic's valuation; Annenberg Public Policy Center polling on data centres; Lucent and Nortel vendor financing; Søren Kierkegaard, The Concept of Anxiety.Related episodes: SpaceX, Anthropic, OpenAI: The $2tn IPO Boom; Google I/O 2026: Sundar Pichai's 25-Year AI Long Game; S2E24 on Google's AI leadership reshuffle.

    AI Shopping Wars. Why OpenAI Quit. Google Didn't and Anthropic Went Free.

    Click here to watch a video of this episode. Walmart's checkout inside ChatGPT converted at a third of the rate of its own site, and six months later OpenAI shut Instant Checkout with twelve Shopify merchants still live. On 2 September, Anthropic shipped the opposite architecture for agentic commerce and took nothing on the sale. What Anthropic learned, why Google is quietly winning, and why the agent that matters is the one lenders want. On Wednesday 2 September, Anthropic open sourced two reference agents for agentic commerce: one facing the shopper, one facing the merchant. They place no orders, touch no card credentials, and hand the cart back to the merchant's own checkout. Shopify, Visa, Mastercard and Accenture were partners on day one. The twist is that OpenAI had already tried to own that checkout, charged 4% on completed orders for the privilege, and watched merchants leave. Meanwhile Google turned the same in-chat checkout on inside Gemini via Google Pay, with Gap live, and can price it at zero for as long as it likes. Aman Narain, solo from Hong Kong this week, breaks down why the agentic commerce fight was never about whether AI can shop but about whether the AI shows up as a supplier or a landlord, and why the agentic commerce blueprint Anthropic gave away is really a distribution channel for embedded lending. Key takeaways:1. A percentage of revenue is rent: it scales with your success and cannot be engineered down, which is why merchants walked away from OpenAI's 4% fee.2. Compute is an input like electricity: it can be cached, shrunk and negotiated, which is why Anthropic priced itself as a supplier.3. Walmart's 3x conversion gap did not prove agents cannot shop. It proved the cash register was in the wrong place.4. Google runs agentic commerce checkout at 0% because it makes its money one layer up in advertising, and that is precisely its trap.5. The merchant agent is an underwriting file assembling itself in real time, which is why Shopify, Stripe and Square, all lenders, integrated on day one. Topics covered:- Walmart's ChatGPT experiment and OpenAI's retreat to discovery- The mechanics of Anthropic's commerce agents: no orders, no cards, no cut- Rent versus compute: why a 4% take rate wipes a direct-to-consumer margin- Three lessons Anthropic welded into the plumbing: price, till, guardrails- Google's Universal Commerce Protocol, Gap on Gemini, and the advertising trap- The 35% larger cart claim, and why vendor-reported ceilings are not forecasts- Shopify switching agentic storefronts on by default- The merchant agent as a real-time underwriting file: Square, Shopify Capital, and the Tuesday stockout- Three companies, three postures, and the closing wager: research lab or underwriter? Chapters:Referenced in this episode: Anthropic Claude Commerce Agents blueprint (2 September 2026); OpenAI Instant Checkout wind-down (March 2026); Walmart's Shoptalk conversion disclosure; Google Universal Commerce Protocol and Gap's Gemini checkout; Google Universal Cart at I/O 2026; Shopify Agentic Storefronts; Square Loans 2024 originations; Shopify Capital; Fast Company reporting on Gemini checkout.

    UPI at 10: The World's Biggest Payment Network Isn't a Company

    Click here to watch a video of this episode. UPI cleared 373 transactions in its first month in 2016. In July 2026 it cleared 23.66 billion in a single month, worth close to 30 lakh crore rupees. Ten years on, the most consequential payments network of the decade turns out not to be a company at all. On 25 August 2016 the Unified Payments Interface went live in Indian app stores, four months after a Mumbai pilot with 21 banks. The architecture was deliberate: a regulator, a non-profit switch, volunteer architects who insisted the centre stay dumb, and private apps free to fight each other on top. The twist is what that fight produced. Google Pay held 62% of UPI volume in 2018 and has since fallen to around 35%, beaten not by a better product but by a field army of QR stands and soundboxes. Aman Narain and Zubin Vandrevala break down how UPI went from 373 transactions to 241 billion a year, why the app that won the ground war now carries the largest regulatory overhang in consumer fintech, and who actually pays for a payment rail that charges merchants nothing. Both were inside Google Pay during the Tez years, so this is an operator's account rather than an anniversary brochure. Key takeaways:1. UPI cleared 241 billion transactions in FY26 against roughly two crore in FY17, a twelve-thousand-fold increase in ten years.2. Google built the better app and PhonePe built the better army; on open rails the army took the crown.3. NPCI's 30% per-app cap, mandated in 2020 and deferred ever since, makes Google Pay's decline and PhonePe's success the same regulatory problem seen from opposite ends.4. India chose a free rail funded by public subsidy; Brazil chose a priced rail at 22 to 23 basis points that funds its own servers.5. UPI carries 85% of India's retail digital payments and 49% of global real-time volume, on infrastructure no company owns. Topics covered:- The India Stack: Aadhaar, payments, data, and the KYC cost that fell from about twenty-three dollars to ten cents- Why abstracting real time, not inventing it, was UPI's actual innovation- Three fights nobody remembers: USSD against IP, banks against third-party apps, SMS OTPs against device binding- How the baton survived a change of government, from the UPA to the NDA- Demonetisation as fire starter rather than cause- Inside Tez: scratch cards, ultrasonic pairing, and a multinational betting on rails it did not own- PhonePe's ground war, and why the last metre in India is physical- The 30% cap, the sovereignty subtext, and the crown that eats- Seven hundred million QR codes in a country that never installed nine million card terminals- Brazil's Pix: the tidier system, and what India's messier bet bought instead Referenced in this episode: UPI pilot, Mumbai, 11 April 2016; public launch 25 August 2016; NPCI incorporated December 2008; IMPS, November 2010; iSPIRT, February 2013; demonetisation, November 2016; PhonePe founded December 2015; RBI action on Paytm Payments Bank, January 2024; NPCI's 30% per-app volume cap; zero MDR since 2020; NPCI International and the acceptance corridors; BIS Project Nexus; Brazil's Pix, November 2020; World Bank on Indian financial inclusion; the 1930 cybercrime helpline.

    The Truth About Google's Brain Drain: It's Not About People, It's About Chips

    Click here to watch a video of this episode. Alphabet lost roughly $200 billion of market value in the eleven days after 5 August, close to a full year of its own AI infrastructure budget. On 14 August, a filing showed Berkshire Hathaway holding $37.8 billion of the same stock. On 5 August, Google DeepMind announced that Demis Hassabis would step back from day to day management to become Chair of Google DeepMind and Chief Scientist of Alphabet. Koray Kavukcuoglu took over as senior vice president reporting to Sundar Pichai. The same morning, chief scientist Jeff Dean left after 27 years, taking Sanjay Ghemawat, Oriol Vinyals and Quoc Le with him to found Discovery Loop. Alphabet is a founding investor and cloud partner in the company its own researchers left to build. Aman Narain and Zubin Vandrevala break down why the Google DeepMind reshuffle was not a talent story at all. It was an argument over TPU allocation between Google DeepMind's researchers and Google Cloud's enterprise arm, and it was settled in Cloud's favour. Key takeaways:1. The reshuffle was not a talent crisis. It was a compute allocation decision, settled in Google Cloud's favour.2. Berkshire's $37.8 billion Alphabet position was built during the second quarter and only disclosed on 14 August. It is not a dip purchase.3. Sergey Brin holds no operating title at Alphabet and shaped the outcome anyway.4. Google DeepMind's independence, protected since the 2014 acquisition, ended at an all-hands on 6 August.5. The $200 billion that came off Alphabet's market value is roughly a full year of its own AI infrastructure budget.

    Stripe's Shopping Spree: OpenRouter, PayPal and the $50 Billion Tell

    Click here to watch a video of this episode. Stripe has agreed to pay more than $7 billion for OpenRouter, a company valued at $1.3 billion in May. In the same season it has bid $60.50 a share, roughly $53 billion, for PayPal. The Collison brothers own a publishing house, and they have stopped collecting books. Over the weekend Bloomberg reported that Stripe had finalised an agreement to acquire OpenRouter, an AI routing layer founded in 2023 that sits in front of more than 400 models. In May the company was valued at $1.3 billion. Stripe reportedly paid more than five times that, months later. Its own founders had described it as the Stripe of AI. The twist is what sits beside it: an unresolved $53 billion bid for PayPal, the company Stripe was founded in 2010 to correct. Aman Narain and Zubin Vandrevala break down what every Stripe acquisition since 2020 has in common, why a Stripe IPO is the most plausible explanation for $50 billion of committed bank financing, and why none of it could have happened to a listed company. Key takeaways:1. Stripe has not been buying revenue since 2020. Paystack bought emerging-market rails, TaxJar and Recko bought the revenue and tax stack, Bridge bought money movement, Privy bought wallets, and OpenRouter buys the routing layer.2. More than $7 billion for a company valued at $1.3 billion in May buys the toll booth between software and the models it transacts through, not eight million users.3. Staying private is what made the sequence possible: no shareholder vote, no proxy circus, no analyst asking about dilution on a call that never happens.4. The $50 billion of committed bank financing behind the PayPal bid, plus a $17 billion equity cheque from Stripe, Advent and Block, is the tell. Lenders ask how they get repaid, and private equity funds run on a clock.5. On this read a Stripe IPO is not the epilogue to the shopping spree. It is the financing plan, and at reported valuations it would beat Aramco's $29 billion record. Topics covered:- Auctomatic, Limerick and the $5 million sale that started it, with Patrick Collison at nineteen- A decade of write, don't buy: why the early acquisitions were footnotes- The shelf since 2020: Paystack, TaxJar, Recko, Lemon Squeezy, Bridge, Privy- What OpenRouter actually is, and why 400-plus models behind one door is a toll booth- The PayPal bid at $60.50 a share, the board's refusal, and the higher price now under negotiation- $3.7 trillion of annual processing and 439 million accounts under one roof- Why the most valuable private company in fintech has stayed private for sixteen years- The $50 billion of committed financing, and what lenders and Advent both need next Chapters:Referenced in this episode: Bloomberg on the OpenRouter agreement; OpenRouter's May valuation of $1.3 billion; the Stripe and Advent International offer of $60.50 a share for PayPal; Wall Street Journal reporting on a higher price under negotiation; Reuters on roughly $50 billion of committed bank financing and a $17 billion equity cheque from Stripe, Advent and Block; Auctomatic, Paystack, TaxJar, Recko, Lemon Squeezy, Bridge and Privy; Stripe's $159 billion February tender and secondary marks nearer $200 billion; Saudi Aramco's $29 billion IPO record.
