MediaTek plugs into Nvidia's rack-level interface, and Nvidia buys $3.5 billion of its convertible bonds the same day.

From the Sep 1, 2026 daily brief

MediaTek and Nvidia announced an expanded collaboration on August 31: MediaTek will adopt Nvidia's NVLink Fusion platform, giving customers building their own XPUs a prevalidated path into Nvidia's rack-scale AI factories, and Nvidia has invested $3.5 billion in convertible bonds issued by MediaTek (MediaTek press room, 08-31). NVLink Fusion is the interface Nvidia opens to partners so their own silicon can attach to its rack-scale platform, and we have covered it twice — our August 27 issue on its extension to NVHBM memory, and our August 29 issue on AWS attaching its own high-bandwidth memory to it. What is new today is that it arrives for the first time carrying a capital investment in the partner itself. What that money buys: another passage published the same day places the deal. Gavin Baker's prescription for challenger chips, in a podcast conversation, is not to fight Nvidia head-on but to plug into it — "there's no need to go head on with NVIDIA. Just pick a niche," and "just try to find a way to plug into his ecosystem." His reason is not performance per watt. It is that "Jensen's data centers are financeable." A building full of standard racks, with a liquid secondary market and someone willing to underwrite residual value, borrows far more in credit markets. A building full of custom silicon that exactly one customer can use is another number entirely (clip via Fireside Alpha, 08-31). Our August 18 issue covered the primary-source counterpart to that sentence: Nvidia's August 17 filing, committing up to $105 billion of residual-value guarantee on an Ohio campus tenanted by OpenAI. So what a challenger has to win is not only performance per watt but whether its buyers can reach money as cheap as the incumbent's — and MediaTek's $3.5 billion is both the entry fee for that route and its price. ⚠️ Baker's remarks exist only as a clipped excerpt, with no transcript and no link to the original audio, so we treat them as "somebody said this"; joining the two events is our inference, and MediaTek's announcement says nothing whatsoever about financing.
