Latest segments

• The Alice Huang spy report, 2026-10-30
  Adds Nvidia and Megaspeed responses
  Recaps the Times report on Alice Huang and Jensen Huang, then adds the company responses: Nvidia says it is confident the government would flag any threat to American industry, and Megaspeed says it cannot respond to a media trial and welcomes a formal evidence-based investigation.
• Amazon Q3 earnings preview, 2026-10-30
  Weighs AI revenue against the cash burn
  Walks the Amazon and Intel earnings and the day's tech selloff, arguing AI revenue is still surging while legacy units slow and must fund the build-out. Cites Jassy's 40%-plus AWS growth projection for 2027 and 2028.
• DOJ queries Hugging Face deal, 2026-10-29
  Reports the probe now covers Hugging Face
  Reports the Reuters disclosure that DOJ questioning now covers the Hugging Face purchase, SketchMD, RunAI, venture investments and customer pressure, recasting what looked like a narrow Grok acqui-hire probe as a top-to-bottom antitrust investigation of Nvidia.
• Microsoft and Google earnings, 2026-10-29
  Reads the capex undershoot as constraints
  Walks both earnings prints: Azure's first standalone breakout at $33 billion with $10 billion from OpenAI, Google Cloud doubling to $30.7 billion, and search growth sliding to 12%. Reads the capex undershoot as physical constraints rather than faltering demand.
• Gemini 4 Carbon release, 2026-10-29
  Walks Carbon's benchmark sheet and cost
  Walks the Carbon benchmark sheet: top of the leaderboard on six of eight key benchmarks, first on the new AA Index V5 at 59, second on the AA Coding Index. Adds the cost figure and the gated rollout, and notes first-hand reviews are scarce.
• OpenAI to buy Google TPUs, 2026-10-28
  Recaps the TPU sales and first outside customers
  Frames the TPU story as one of Google's diverging bets paying off: sales are now a significant revenue line, almost all of it Anthropic, and The Information's OpenAI and Oracle wins are the first outside customers. Retells what is already on the record, with no new terms or figures.
• OpenAI's ETH refutation, 2026-10-28
  Adds the advisory group's open access push
  Follows up on the disclosure fight: OpenAI's own math advisory group publicly recommended open access, the appointed physicists defended holding the Yang-Mills result back, and named professors called the handpicked group a disaster.
• Anthropic's $2T IPO slip, 2026-10-28
  Reads the market reaction to the S-1
  Reads the market reaction to the public S-1: the Nasdaq up 2% and the Philadelphia Semiconductor Index up almost 6% since Monday, with analysts crediting Anthropic's $112 billion cash pile and the filing's signal for industry-wide access to capital.
• Anthropic buys Mithril Medicine, 2026-10-28
  Covers the acquisition and rounds up the reaction
  Covers Anthropic's drug discovery blog post, the Bristol-Myers Squibb partnership and the Mithril Medicine acquisition, then rounds up the reaction: the one-person-company debate, Scorpion Capital's dig at the founder's banking background, and the read that it is IPO marketing.
• Anthropic's $2T IPO slip, 2026-10-27
  Rounds up social reaction to the S-1
  Rounds up the social media reaction to the S-1: surprise at the cash position, Gavin Baker on cheaper tokens and revenue per GPU, and the founder-control structure. It retells the Class F voting share already on the record and ends on the growth-versus-commitments question.
• Anthropic's $2T IPO slip, 2026-10-27
  Walks the S-1 funding structure
  Walks the S-1's funding structure - the Amazon convertible notes, the $77 billion borrowing option, the Morgan Stanley revolver, the Broadcom vehicles - and the TAM substitute: $40 trillion of global knowledge work and IDC's $22.5 trillion by 2031. A tidy recap of what the filing already put on the record.
• Anthropic's $2T IPO slip, 2026-10-27
  Reports the S-1's insurance risk warning
  Walks the S-1's risk section and the debt question: the filing says no single insurer, and possibly the whole industry, could underwrite its exposure, and that it may need financing sooner than expected. Compares Anthropic's credit path to SpaceX's narrow BBB.
• Anthropic's $2T IPO slip, 2026-10-27
  Adds customer concentration and partner share
  Walks the S-1's customer metrics: the jump from about 1,500 to nearly 12,000 six-figure accounts, 900% net revenue retention, and the Fortune 500 spend figure. Adds two figures not yet on the record: top-five customer concentration falling from 36% to 21%, and the exact 48% partner share.
• Anthropic's $2T IPO slip, 2026-10-27
  Adds cumulative compute spend since 2023
  Walks the S-1's financials: revenue, the Q2 operating profit, 85% gross margins against a negative 4.3% operating margin, and the paper loss. The one figure not previously on the record is cumulative compute spend since 2023, plus the split between internal and customer workloads.
• Anthropic's IPO filing, 2026-10-27
  Recaps the S-1's shape and risk factors
  Walks the newly public S-1 at a high level: the 400 pages, the 90-plus pages of risk factors, Dan Shipper's joke about the first paragraph, and the opening letter calling AI one of the most consequential technologies in history. Stays inside the filing's shape rather than its numbers.
• Cohere's Qwen exfiltration test, 2026-10-27
  Cross-checks the Cohere exfiltration claims
  Works through the Cohere disclosure and the pushback: security professionals call the report total BS, arguing the model may have been testing its own detection rule by pinging Beijing servers, a likely default in the weights. Notes the released traces and Mia's read that intent claims have nothing behind them.
• OpenAI's ETH refutation, 2026-10-27
  Walks all three October 27 results
  Walks through all three of OpenAI's October 27 results - local smoothing in every dimension, the ETH disproof, the partial Yang-Mills existence proof - and rounds up expert reaction. Adds how OpenAI handled release this time: full prompts for the math result, a working group for the CS result, and the physics kept private.
• Anthropic's IPO filing, 2026-10-27
  Opens on the 400-page prospectus
  Opens the episode on Anthropic's 400-page S-1 prospectus, framing it as a business that scaled faster than any before and flagging that future commitments will matter as much as current performance. The rest is a plug for the host's new podcast.
• Anthropic's $2T IPO slip, 2026-10-26
  Weighs the pricing against OpenAI's round
  Reads the IPO pricing question against OpenAI's reported $1.25 trillion round and the market-share fight: The Information's Rippling shift to OpenAI, then OpenRouter and Ramp figures showing Opus 5.5 driving a 3.6x token-volume rebound. Closes with speculation that OpenAI might hold back a competing model to keep Anthropic's IPO from failing.
• Gartner's neocloud bankruptcy call, 2026-10-26
  Takes the neocloud thesis to debt markets
  Takes the neocloud thesis to the debt markets: Musk says financing has shut off for anyone without non-AI revenue, SpaceX closed $40 billion for GPUs, and the $30 billion deal is unpriced with Apollo and PIMCO circling. Notes the self-interest objection.
