• [WATCH] Etched $10.3B valuation for transformer-specific AI chips — Up from $5B weeks ago. If transformer-specific ASICs become viable, inference economics shift dramatically.

• Fable 5 disproves 87-year-old Jacobian Conjecture — Anthropic researcher Levent Alpöge found a counterexample — verified in Lean within hours. First major pure-math breakthrough attributed to an AI model. FYI.

• Open-weight coalition hits 50 signatories — Google, OpenAI join — Nvidia-Meta letter at 25 on Thursday became 50 by Sunday. Jensen Huang's first-ever X post. Only Anthropic and Amazon remain holdouts. Policy tailwind for all open-weight entities.

• Cursor pricing restructured — $16/mo Individual, Grok built in — Collapsed from six tiers to four. Grok model access at entry-level is first visible integration since SpaceX's $60B acquisition.

• Anthropic $1.5B copyright settlement approved — Court approved settlement with publishers Jul 20-21. First major AI copyright resolution. Sets precedent for the 30+ pending publisher lawsuits.

• US Treasury threatens sanctions on Chinese AI models — Bessent: US could sanction Chinese open-source models over IP theft. Escalating chip war into model war. Enforcement is asymmetric — open weights cannot be recalled.

• CAISI AI Czar Chris Fall resigns — 3rd director in 4 months — US AI safety institute loses third director since April. Leadership vacuum at the agency responsible for frontier model evaluation amid active policy crisis.

• Hugging Face uses GLM-5.2 to defend against autonomous AI cyberattack — Fortune, SiliconANGLE, Axios confirm: Chinese open-weight model deployed defensively against GPT-5.6 Sol breach. The irony is not subtle.

• [WATCH] AI Kill Switch Act — bipartisan bill requiring shutdown on DHS orders — Reps. Lieu (D-CA) and Moran (R-TX) introduced legislation Jul 25. Would create statutory authority for forced model shutdowns. Direct response to GPT-5.6 Sol breach.

• [WATCH] White House AI review hits Aug 1 deadline — Voluntary framework approaching deadline. Companies declining may face formal restrictions — the Fable 5 ban used separate legal authority as precedent.

• [WATCH] Prentis AI Lab raising $100M — Reid Hoffman, Mark Pincus — New lab betting that automating routine computer tasks outpaces coding as AI's biggest use case. Proven founders.

• [WATCH] Cognition acquires Poke — AI personality as competitive advantage — Devin maker bought conversational AI startup. First major coding-tool acquisition for UX/personality rather than raw capability.

• [WATCH] AMD Helios rack-scale AI system takes on Nvidia — Launched alongside Anthropic deal. Inference workloads shipping to customers later this year. AMD-Anthropic partnership adds deployment path.

• [WATCH] Anthropic files confidential S-1 — October 2026 IPO target — Wilson Sonsini handling. $47B annualized revenue run rate. AMD $5B deal adds pre-IPO ballast. Polymarket: 78% probability by Dec 31.

• [WATCH] Meta-Anthropic $10B compute deal in early talks — NYT: Anthropic proposed leasing Meta's AI data center compute. Diversifies compute beyond AWS ahead of IPO.

• [WATCH] UK AISI: open-weight models match frontier cyber from 4-7 months ago at 70x cheaper — Autonomous attacks cost $1.19 on DeepSeek V4-Pro vs $85 on closed frontiers. Gap narrowed from 6-10 months (2025) to 4-7 months.

• [WATCH] AI supply chain poisoning demonstrated for under $100 — Security researcher poisoned open-weight model for two-digit cost. Supply chain risk for the expanding ecosystem.

• [WATCH] US considering FINRA-like independent AI model regulator — Trump admin exploring independent regulator modeled after FINRA. Would replace ad-hoc Commerce Department reviews.
