Nvidia announced on Aug. 31 that it would take $3.5 billion of MediaTek's euro-convertible bonds. It marks the first time Nvidia has directly committed funds of this size to a Taiwanese company.

MediaTek said the same day that pricing of its first unsecured overseas convertible bond issue had been completed. Total proceeds reach $3.9 billion, more than NT$120 billion, the largest convertible bond issue in Taiwan's capital market.

The two companies are widening cooperation from edge computing into AI data centres, custom AI chips, PCs and smart vehicles. MediaTek will adopt Nvidia's NVLink Fusion platform to help customers develop bespoke XPUs and build rack-scale AI installations.

Nvidia chief executive Jensen Huang said the roadmap the two are executing spans a decade rather than a year or two, covering edge AI, PC chips and data centre XPUs.

A convertible bond is debt that can be exchanged for equity under set conditions. The buyer supplies capital while retaining an option on future ownership; the issuer raises funds without immediate dilution.

The deal sits alongside a broader blurring of the line between general-purpose GPUs and custom silicon in the AI chip market. As large cloud operators design more of their own chips, firms with design capability have grown more valuable.

There are implications for Korea's semiconductor industry as well. Forms of design collaboration are diversifying beyond memory and foundry work, and a company's position in the supply chain is increasingly what separates valuations.
