Nvidia’s $3.5 billion investment highlights MediaTek as key player in AI chipmaking

Nvidia just wrote a $3.5 billion check to a company most people associate with the chips inside their budget smartphones. That company, Taiwan-based MediaTek, is now officially positioned as one of the most important players in the AI silicon race.

The investment, made through convertible bonds, represents Nvidia’s largest direct financial commitment outside the US. It’s part of a broader $3.9 billion overseas convertible bond offering from MediaTek, which also attracted participation from Alphabet.

What the deal actually involves

The partnership goes well beyond a passive financial stake. Nvidia and MediaTek are collaborating across three major domains: AI infrastructure, local and edge AI computing, and automotive platforms for AI-driven vehicles.

At the technical core sits Nvidia’s NVLink Fusion platform, which enables MediaTek to design custom AI accelerators, known as XPUs, that plug directly into Nvidia’s broader data center ecosystem.

This isn’t a cold introduction between the two companies. They previously worked together on the RTX Spark PC chip earlier in 2026, so the relationship already had some mileage on it before the billions started flowing.

Nvidia CEO Jensen Huang described the arrangement as a long-term collaboration focused on transforming AI solutions. MediaTek CEO Rick Tsai framed it as a natural pairing of Nvidia’s accelerated computing prowess with MediaTek’s deep expertise in custom silicon design.

Why MediaTek, and why now

MediaTek is targeting $2 billion in revenue from its custom AI chip segment this year, with ambitions to capture up to 15% of what it estimates will be an $80 billion addressable market by 2027.

The market responded enthusiastically. MediaTek’s shares climbed roughly 10% after the announcement, reflecting investor confidence that the partnership could accelerate the company’s AI ambitions considerably.
