The signal

  1. Nvidia buys $3.5B in convertible bonds tied to MediaTek, its largest direct investment outside the US What happened: Nvidia will purchase bonds convertible into MediaTek shares, with MediaTek adopting Nvidia’s NVLink Fusion interconnect to build custom accelerators and AI-vehicle silicon that plug into Nvidia’s rack-scale systems. Why it matters: hyperscalers and labs (Amazon, Google, Microsoft, OpenAI, Anthropic) are all building their own chips to cut Nvidia dependence; locking a major merchant chipmaker into NVLink Fusion is Nvidia’s way of staying the connective tissue even as it cedes some silicon share.

Since last brief

  • Anthropic/Pentagon: DoD’s GenAI.mil portal went live with ChatGPT Mil and Grok for Government joining Gemini for 3M personnel. Claude is still absent, despite Judge Lin’s Aug 27 ruling that the Pentagon’s supply-chain-risk label was unconstitutional retaliation — the DC Circuit case that keeps the label formally in effect hasn’t moved.

Other

  • Nvidia’s Rubin CPX inference chip, believed dead after vanishing from the GTC 2026 roadmap, is reportedly back with a redesign (168GB HBM4, new rack layout) and a Q1 2027 production target, per analyst Ming-Chi Kuo — unconfirmed by Nvidia itself. Benzinga (independent, analyst claim)
