Nvidia invests $3.5B in MediaTek convertible bonds

Nvidia parked $3.5 billion in MediaTek convertible bonds and widened a chip partnership that now runs from data-center racks to car dashboards. The two companies spelled that out in a joint newsroom release on Monday.

A convertible bond is debt that can turn into equity later, on terms set when it is issued. Nvidia bought $3.5 billion of that paper from MediaTek (TWSE: 2454). It did not take a $3.5 billion equity stake, sign a plain loan, or buy the company. The release gives the dollar figure and nothing else: no conversion price, no coupon, no maturity, and no word on what MediaTek will do with the cash.

The money sits on a three-part collaboration. On AI infrastructure, MediaTek will adopt Nvidia's NVLink Fusion platform, the path that lets customers build custom XPUs and drop them into NVLink-connected, rack-scale systems. That bundle includes the NVLink Fusion chiplet, NVLink-C2C, and NVHBM.

On PCs, the companies keep working on RTX Spark and DGX Spark chips, where the GB10 Grace Blackwell Superchip already pairs a Blackwell GPU and a Grace CPU over NVLink-C2C. In cars, MediaTek Dimensity Auto platforms will integrate Nvidia technology and can run alongside Nvidia DRIVE AGX. "AI is transforming every computing platform, from the world's largest AI factories to the PC and the car," Nvidia founder and CEO Jensen Huang said in the release.

The silicon story is straightforward. The financing argument is not. Reuters said the bond purchase could feed investor worry about circular financing in AI, another case of Nvidia helping fund a company that then builds around Nvidia's platform. That framing is the market's, not Nvidia's own language.

It follows a run of Nvidia checks already under a microscope, from paused AI-cloud revenue-share deals to a company that just guided to a $108 billion quarter. NVLink Fusion is how custom XPUs get pulled into Nvidia's racks whether or not the bonds ever convert. The conversion price and maturity still have to show up in a filing.
