Delphi Digital The Worst Is Behind Us

• Kevin Kevin lays out the AI CapEx hurdle: roughly $4T through 2029 at a 12% return implies about $500B in free cash flow, or $1T of revenue at 50% gross margins. Another speaker argues there are plausible ways to reach the numbers: Anthropic grew from $5B in Q1 to $16B in Q3, while Nvidia is growing …
• Delphi Digital The near-term AI risk is reflexive demand, not simply debt. New labs trying to compete with Anthropic and OpenAI have raised $40B since 2024, and much of that money may go toward training and model …

BG2 Jensen Huang | Does AI Revenue Justify Capex, '27 AI Bottlenecks, Singularity, Open vs Closed & more

• Jensen Huang Jensen Huang’s core compute call is that AI demand compounds twice: reasoning consumes vastly more inference, and useful intelligence gets hired for vastly more work. Agents preserve “strategic optionality,” explore alternatives, reflect, prune and use tools; memory systems and software harnesses turn …
• Huang expects falling intelligence costs to expand ambition rather than reduce spending or work. Gerstner cited roughly 10,000 agents and an estimated $4 million of compute behind the cited Navier–Stokes advance, while estimating that a …
• The capex case does not require OpenAI and Anthropic to reach trillion-dollar revenue because Huang sees AI infrastructure demand distributed across three large pools. Roughly one-third is conventional processing and simulation growing about 30–40%; perhaps a quarter of compute, representing not quite …

Nicholas Thompson Why Ray Dalio is Worried About an AI Bubble

• Ray Dalio Dalio’s central warning is that transformative AI can still be a terrible investment at the wrong price. Previous breakthroughs—from household electricity to radio, cars, and airplanes—attracted capital because their potential was real, yet …
• Nicholas Thompson The bubble mechanism begins when paper wealth grows much faster than available cash. A company can raise $50 at a $1 billion valuation, instantly creating nominal wealth, but “wealth is not money”: spending requires owners to …
• Ray Dalio Dalio’s bubble indicator puts current conditions in the same order of magnitude as 2000 and 1929. He characterizes 2008 as a smaller, more debt-intensive housing bubble; today’s danger is unusually concentrated across GDP, wealth, …
• Nicholas Thompson A productivity miracle only solves the debt problem if it becomes taxable income quickly enough. Thompson’s bull case is a 10-fold productivity era powered by “geniuses in the data center”; Dalio concedes that sufficient income growth …

New Money 'Big Short' Investor Explains How the AI Bubble Will Burst

• Steve Eisman Steve Eisman sees AI’s immediate danger as concentration, not lack of demand. Nvidia grew revenue roughly 110%, yet 70% of its accounts receivable came from five customers; meanwhile, OpenAI and Anthropic reportedly …
• OpenAI looks like the weaker link because its costs are outrunning already-rapid revenue growth. Eisman cited roughly $6.5 billion of quarterly revenue against about $12 billion of costs, with revenue rising $1 billion while costs rose …
• The capital loop can hold only while the model companies keep growing and their strategic backers keep funding them. Eisman had assumed venture capital supplied most of the money, but said Amazon, Google, Microsoft, Nvidia and SoftBank are the major …
• Hyperscalers retain scale moats, but AI capex has transformed their cash-flow profile and exposed them to fragile customers. Eisman cited approximately $700 billion of hyperscaler AI spending this year, Oracle’s heavy dependence on OpenAI commitments, and Google …
