Nvidia Invests $3.5B in MediaTek for Custom AI Chips

Nvidia Buys Into the Company Building Everyone Else's Chips

Nvidia announced on August 31, 2026 that it has purchased $3.5 billion of convertible bonds issued by Taiwan's MediaTek. The bonds are part of a larger $3.9 billion offering, meaning Nvidia took the overwhelming majority of it. Alphabet also participated, at an undisclosed size.

The financial headline is the number. The strategic headline is what came attached to it: MediaTek is adopting NVLink Fusion, Nvidia's interconnect technology for wiring third-party silicon into Nvidia-based data-center systems.

• $3.5 billion in convertible bonds out of a $3.9 billion MediaTek offering, with Alphabet also participating
• MediaTek adopts NVLink Fusion, letting its customers design custom AI chips that plug into Nvidia rack-scale systems
• MediaTek projects roughly $2 billion in 2026 revenue from its custom data-center ASIC business
• The partnership extends existing work on RTX Spark and DGX Spark PC silicon and on Dimensity Auto automotive platforms

What Is NVLink Fusion, in Plain Terms?

NVLink is the high-bandwidth link Nvidia uses to make many GPUs behave like one very large one. NVLink Fusion opens that fabric to chips Nvidia did not make — supplying the connectors, the memory semantics and the rack-scale architecture so a partner's custom accelerator can sit inside an Nvidia-shaped system.

That is a deliberate loosening of a moat, and it is worth understanding why a company would do that.

Why Would Nvidia Fund a Competitor's Supply Chain?

Because MediaTek is not really the competitor. The hyperscalers are.

Amazon, Google and Microsoft have all been building in-house accelerators to reduce how much they spend on Nvidia GPUs, and MediaTek is one of the design houses that helps customers turn that ambition into silicon. If those custom chips are going to exist regardless, Nvidia would rather they be born inside its interconnect and rack architecture than outside it.

Jensen Huang addressed the circularity question head-on, saying: "This is not circular because obviously they do their own business and we do our own business." Investors can weigh that for themselves — Nvidia has made a series of ecosystem investments this year and the pattern has drawn scrutiny. What is not in dispute is the direction: Nvidia is trading some exclusivity for a much wider installed base of systems that speak its language.

What Should Investors Actually Watch Here?

Three things, in order of usefulness.

First, MediaTek's custom ASIC revenue. The company is guiding to roughly $2 billion for 2026 in that segment. Whether NVLink Fusion access accelerates that number in 2027 is the cleanest test of whether the partnership does what both sides say it will.

Second, the convertible structure. Convertible bonds mean Nvidia gets downside protection now and potential equity later — a notably more cautious instrument than a straight stake, and a reasonable read on how Nvidia sizes the risk.

Third, attach rates. If custom accelerators built by MediaTek customers end up racked next to Nvidia GPUs rather than instead of them, the strategy is working.

For the wider picture on where this fits, we covered Nvidia's Q2 FY27 results, where revenue doubled to $96.2 billion and the $6 billion Poolside model factory licensing deal, both of which show the same instinct — spend to make the ecosystem denser rather than defend a single product line. It is an expensive strategy, and so far the stock market has largely gone along with it.
