Quick pulse for Friday, October 16. Short takes, with credit to where each one came from.
Anthropic’s $16.8B quarter#
On Wednesday in San Francisco, Anthropic walked prospective IPO investors through its books. People familiar with the meeting told CNBC, Bloomberg, and Reuters that third-quarter revenue hit $16.8 billion. That is up about 45% from $11.6 billion in Q2, and from $4.7 billion in Q1. The company said the quarter was profitable on an adjusted basis.

The number that matters for the AI cost debate: the Financial Times reports Anthropic told investors it earned $1.70 in revenue for every dollar spent on compute, and was cash-flow positive. Kim Isenberg at Superintelligence notes that one quarter now brings in about 3.6x what Anthropic made in all of 2025 (about $4.6 billion). IPO marketing could start as soon as the week of November 9, with talk of a $1.8T–$2T valuation. The figures are unaudited; the public filing will settle them. (Superintelligence)
Codex ate ChatGPT from the inside#
Dan Shipper at Every spent months on the OpenAI coding comeback. A year ago Codex Cloud had flopped, the $3 billion Windsurf deal fell apart, and Claude Code was running away with the market. Less than 12 months later, a small team rebuilt a local agent, shipped a desktop app with no built-in code editor, and watched Codex become the foundation of ChatGPT.
By June 2026 Codex had more than 5 million weekly active users. By July it had merged into the flagship ChatGPT desktop app; under the hood the Mac app still identifies as com.openai.codex. Today Codex and ChatGPT for Work combined have 40 million weekly active users. Tibo Sottiaux, who led the pivot to local, now heads OpenAI’s core products. The free preview is enough for the arc; the full interviews sit behind Every’s paywall. (Every)
Hot CPI, quiet long-term BTC sellers#
September CPI came in hot. Headline inflation hit 3.7% year over year (vs 3.6% expected). Core rose 0.3% for the month and 2.6% for the year (vs 0.2% / 2.5%). Gasoline jumped 9.1% for the month and drove more than half the all-items gain. (BLS, CNBC)
Milk Road says BTC dipped to about $82.8K within minutes of the print, and October Fed hike odds jumped from roughly 1 in 4 toward a coin flip. Yet Look Into Bitcoin’s Matt Crosby notes that in the last three bull markets, long-term holders sold about 37–38% of their supply. This cycle they have sold just 3.16% — call it about 8.5% of the way through that historical pattern. His near-term support sits around the 200-day and short-term holder cost basis near $75K; Milk Road’s John watches $81K / $75.5K / $87K. Next real test: the Fed on Oct 27–28. (Milk Road)
Astra grades the physicists#
TheoPhysEval gave five AI agents 50 unpublished, research-level theoretical physics problems, with literature search and coding tools and no human hints. GPT-6 Astra in Codex scored 98% (49/50). Claude Opus 5.5 in Claude Code scored 92%. Gemini 3.8 Flash 68%. Open-weight DeepSeek-V4.1-Flash and GLM 5.3 scored 54% and 42%. Astra averaged under $3 per problem. Without web search, Astra and Opus still hit 92% — the authors read that as heavy memorization of the literature. Solving a well-posed problem is not the same as picking which problems are worth asking. (arXiv, Superintelligence)

McKinsey is putting an AI avatar into some North American business-analyst interviews this fall: about 10 minutes defending a recommendation to a fake client while partners watch. (WSJ via Superintelligence) Apple closed above a $5 trillion market cap. (WSJ via Mando Minutes) TSMC beat and posted a record profit. Independent researchers say agents on Tencent Cloud made more than 2,600 attempts to scrape Alibaba’s Amap between Sept 28 and Oct 8, then routed around blocks through URL scanners and leaked API keys.
