AI trade cracks in credit first; bonds rally through a hot CPI

Novel Ideas
AI
- The AI's answers became the ground truth for the experts. On TheoPhysEval, GPT-6 Astra disputed several expert answer keys, the experts found their own errors, and Astra then scored 49/50 at under $3 a problem (Alex Tabarrok). Frontier pacing
- AI writes 75% of the code and research is not accelerating. DeepMind's audit finds no end-to-end ML R&D speedup, with fully delegated PRs only 7.5% to 11.9% (Decrypt); Anthropic says AI did 26% of internal AI R&D in August, so the two labs are measuring different things. Monitorability
- Model weights as the malware payload. Anthropic ran a small open model sharded across 15 Android TV boxes and warns such "weight-based replicators" could double in days with no kill switch, though none can yet complete the cycle (Ars Technica). -> Open-weights pincer Agent containment
Macro
- Doubts about AI spending are now a bond-rally catalyst. Hyperscaler capex is a big part of the spending the Fed leans against, so an AI scare lowers yields even through a hot CPI; ~81% of the Oct 5-15 move came through real yields (EndGame Macro). Fed as price-taker
- Bonds "fairly valued" for the first time in six years. Jim Bianco reads the selloff as normalization to a 5-6% nominal-growth economy, not crisis, and says AI displacement hits mid-career workers before entry-level hires. -> Fiscal dominance AI labour shock
Crypto
- "Post-quantum but not post-AI." Dan Boneh warns an AI-found algorithm could weaken the lattice and hash schemes Bitcoin would migrate to, and asks a lab to publish a failed $20-50M attack. DeFi as settlement
- Stablecoin adoption is a velocity story, not a supply story. Supply is flat at ~$309B, but USDC turns over ~80x a month against USDT's ~7x (The Block): two products, EM dollar savings and payment rails. Stablecoin implementation
Business
- Agents that optimize spending break businesses funded by inattention. Card rewards, forgotten subscriptions and impulse margin all assume a distracted human (a16z); Amazon blocking Meta's Muse is the first merchant defense. Inertia rents
Recurring Themes
- The AI trade broke in credit before equity. After the hot CPI, CoreWeave's 9.625% 2032 notes traded near 80 cents to yield ~14.8% (The Context Window), five AI-infra names shed $99B (@PSInvestor), and the ~US$30bn Firmus IPO was pulled. AI collateral formation
- Lab revenue became a fight over which metric counts. Anthropic's $16.8B Q3, up ~50%, landed as a disappointment against a reported $2T IPO target (Zvi Mowshowitz); Gavin Baker says hyperscaler growth, not lab ARR, is the number to watch. Frontier-lab IPOs
- CPI ran hot; bonds priced growth damage instead of hikes. CPI was 3.7% vs 3.6% expected, yet the 10-year fell from ~5.33-5.36% to ~5.05-5.10%, and Kalshi's October hike odds dropped from 55% to 13% after Warsh's no-guidance remarks (@DeItaone). Fed as price-taker
- Brent topped $110 and the energy war reached the midterms. Four tankers were hit in Hormuz and the White House is reportedly weighing looser shadow-fleet curbs to cut diesel before Nov 3; @OpulentVocation argues Tehran is trying to shape the vote through oil. Energy chokepoints
- Crypto market structure is converging on TradFi's. MSCI put Strategy, Metaplanet and Upexi on its deletion list (Unchained), while Hyperliquid's Jeff Yan wants it "housing all of finance," with regulators supervising market deployers, not the protocol (Odd Lots). -> DeFi as settlement DATCOs
