Nvidia and MediaTek have announced an expanded partnership across three areas — AI infrastructure, on-device AI compute and software-defined vehicles — alongside an investment of $3.5bn in convertible bonds issued by MediaTek. Both companies' releases use that wording. Much of the coverage does not.
Bond, not equity
A convertible bond is debt carrying a right to convert into shares later. "Nvidia buys stake in MediaTek" describes something that has not happened: there is no share position today, only an option on one, and the conversion terms are what would determine its eventual size. The distinction matters for anyone modelling either balance sheet.
What NVLink Fusion actually opens
The technical core is MediaTek adopting NVLink Fusion, with an NVLink Fusion chiplet, NVLink-C2C and NVHBM. That lets MediaTek's ASIC customers connect custom accelerators into Nvidia rack-scale systems. Read carefully, this is Nvidia paying to have the main alternative to its own GPUs — customer-designed silicon — born inside its interconnect rather than outside it. It is not Nvidia outsourcing GPU design to MediaTek, which is the other misreading in circulation.
The figures that are not in the releases
Widely repeated details — a total issue of roughly $3.9bn, a zero coupon, 2027 maturity, Nvidia taking about 90% of it, Alphabet participating in the same placement — appear nowhere in either press release. They come from filings and secondary reporting. Two consequences: $3.5bn is not the size of the issue, and any statement about the coupon or Alphabet's share should carry an attribution rather than being presented as company disclosure.
The part that is not new
The joint PC silicon — Nvidia RTX and DGX Spark-class machines pairing an Nvidia GPU with a MediaTek SoC — continues work the two have already been doing, not a product introduced by this announcement. Treating it as new inflates the scope of the deal. What is genuinely new is a supplier financing its customer at this scale: the same practice Nvidia already draws investor criticism for, now applied to Taiwan's largest fabless chip designer.
